Description
FIELD OF THE INVENTION
[0001] The present invention relates to a container provided with a
pump for discharging bubbles which is capable of bubbling up liquid
(for instance, liquid for cleansing foam, liquid for shaving cream
and the like) received in a container body to make the liquid flow
in a foamy state.
BACKGROUND OF THE INVENTION
[0002] For instance, the container disclosed in International
Publication No. WO92/08657 can be exemplified as a container with a
pump for discharging bubbles. The container is provided with a
container body for receiving liquid having a bubbling property such
as a liquid detergent and a pump for discharging bubbles provided
on a neck portion of the container body, and they are constructed
so that, by depressing a pump head of the pump for discharging
bubbles, the liquid is pumped up from the container body and the
air is sucked from the outside of the carrier. body to mix the
liquid and the air. And then, the vapor-liquid mixture is bubbled
via a net (bubbling member) provided within the pump and the
bubbles are discharged from a nozzle of the pump head.
[0003] The pump for discharging bubbles has had various problems as
follows.
[0004] (a) It sometimes happens that the sucked outside air
intrudes into the container body to bubble the liquid, and the
liquid surface within the container body is filled with the
bubbles, when the bubbles are discharged.
[0005] (b) It is difficult to discharge the bubbles in a straight
line form relatively for a long range.
[0006] (c) A coil spring for energizing the pump head upwards all
the time is received in a region where it is in contact with the
liquid, and the contact of the coil spring with the liquid may be
not desirable depending on the kind of the liquid received in the
container body,
[0007] (d) It is not possible to change a discharging form of the
bubbles.
[0008] (e) There is the possibility that only the air passes
through the net (bubbling member) before the liquid passes through
the net at the first stage of discharging bubbles, and the bubbles
will be discharged unseemly in that case, because the liquid which
has remained within the net at the last discharging is formed into
larger bubbles by flow of only the air and the large bubbles are
discharged from the nozzle of the pump head.
[0009] (f) It sometimes happens that the balance of the volumes of
the liquid and air to be mixed is lost and the liquid volume
becomes smaller than the air volume, and accordingly the bubbling
will be incomplete at the first stage of discharging bubbles.
[0010] Although the container disclosed Japanese Patent Application
No. 6-136411(1994) exists as a container with a pump for
discharging bubbles improved in the point of (f), it also leaves
room for improvements as follows.
[0011] (g) It is difficult to change the size of bubbles (diameter
of the bubbles).
[0012] (h) A measure for preventing a undesired leakage of liquid
which is likely to occur when the container is overturned and so on
is not complete.
[0013] (e) It sometimes happens that the bubbles adhered to the net
(bubbling member) gets dry to clog the net when it is not used, and
the bubbles will be formed badly hereafter.
[0014] An object of the present invention is to provide a container
with a pump for discharging bubbles in which the liquid is not
bubbled before it is bubbled in a bubbling member so that the
container body will not be filled with bubbles; a container with a
pump for discharging bubbles which is capable of discharging the
bubbles in a straight line form relatively for a long range; a
container with a pump for discharging bubbles in which a coil
spring for energizing a pump head upwards all the time is provided
in a position isolated from the liquid; a container with a pump for
discharging bubbles which is capable of changing a discharging form
of bubbles; a container with a pump for discharging bubble which is
capable of discharging bubbles stably in a state that the size of
bubbles is fixed from the first stage of discharging bubbles; a
container with a pump for discharging bubbles which is capable of
changing the diameter of bubbles easily; a container with a pump
for discharging bubbles which is capable of preventing an
undesirable leakage of liquid and a container with a pump for
discharging bubbles in which the net (bubbling member) in not
clogged up due to drying.

[0256] The first piston 50 is formed in a hollow cylinder shape in
which the upper and lower ends are opened, the lower part of the
first piston 50 functions as a seal portion 51 which slides on the
internal surface of the small-diameter cylinder portion 24
fluid-tightly, and the upper part opening margin of the first
piston 50 functions as a valve seat 52.
[0257] The upper-part valve body 35 of the liquid suction valve 30
is projected upward from the upper-part opening of the first piston
50 and can be brought into contact with and detached from the valve
seat 52 of the first piston 50, and opens and closes the upper-part
opening of the first piston 50.
[0258] As shown in FIG. 1, normally, the small-diameter portion 34
of the liquid suction valve 30 is inserted into the first piston 50
in a state that there is enough space between the small-diameter
portion 34 and the internal surface of the first piston 50. As
shown in FIG. 2, when the stem 40 is descended by depressing the
pump head 100, the large-diameter portion 33 of the liquid suction
valve 30 can be intruded into the first piston 50 in a state that
there is a little space between the internal surface of the first
piston 50 and the large-diameter portion 33, and a liquid passage
is secured by the vertical groove 33a.
[0259] The coil spring 39 is provided between the upper end of the
vertical rib 26 in the cylinder member 20 and the first piston 50
and energizes the first piston 50 upward. On the other hand, the
engagement pin 32 of the liquid suction valve 30 can hold the lower
end of the coil spring engagedly from the downward, and accordingly
controls the upper limit of the liquid suction valve 30 when it is
moved upward.
[0260] The stem 40 is formed in a cylinder shape in which the upper
and lower ends are opened, and is received within the
large-diameter cylinder portion 22 and the small-diameter cylinder
portion 24 in a state that it can be moved upward and downward. The
upper part of the first piston 50 is inserted into the lower part
of the stem 40 fixedly so that the seal portion 51 is projected
from the lower part of the stem 40.
[0261] An annular valve seat 41 which is projected in a cross
section of an L-like shape is formed in the inside upper part of
the stem 40. In the inside of the stem 40, the upper side of the
valve seat 41 functions as a vapor-liquid mixing chamber 46, and
the spherical liquid discharge valve 70 which can be brought into
contact with and separated from the valve seat 41 is received
therein in a state that it can be moved.
[0262] In the inside of the stem 40, a plurality of vertical ribs
42 which are extended in the vertical direction are provided on the
portion from a position upper than the region to which the first
piston 30 is fixed, up to the lower part of the-valve seat 41, in a
state that they are dispersed with respect to the circumferential
direction. As shown in FIG. 2, when the stem 40 is descended by
depressing the pump head 100, the upper part valve body 35 and the
small diameter portion 34 of the liquid suction valve 30 can be
intruded into the inside of the vertical rib 42, and the space
between the vertical ribs 42 and the vertical groove 34a in the
small-diameter portion 34 of the liquid suction valve 30 functions
as a liquid passage at the time.
[0263] The pump head 100 connected to the upper part of the stem 40
is provided with an outside cylinder member 110 and an inside
cylinder member 120. The inside cylinder member 120 is formed in a
hollow cylinder shape in which the upper and lower ends are opened
and is provided with a small-diameter portion (bubble flow portion)
121, a medium-diameter portion 122 and a large-diameter portion 123
from top to bottom, and a skirt cylinder portion 124 whose diameter
is larger than the large-diameter portion 123 is linked to the
lower end of the large-diameter portion 123. Besides, in the inside
of the skirt cylinder portion 124, a cylinder-shaped valve body 125
is formed projectingly on the downward extension of the
large-diameter portion 123.
[0264] In the small-diameter portion 121 of the inside cylinder
member 120, two discharging holes 121a and 121b which are different
in diameters are opened in a position where they are separated one
another at 180 degrees with respect to the circumferential
direction.
[0265] The upper part of the stem 40 is fitted into the inside of
the large-diameter portion 123 of the inside cylinder member 120 to
be fixed. Besides, the internal surface of the large-diameter
portion 123 is provided with a plurality of vertical grooves 123a
which are extended in the vertical direction in a state that they
are dispersed with respect to the circumferential direction. The
upper end of the vertical groove 123a is extended to the position a
little upper than the upper end of the stem 40, and the vertical
groove 123a functions as a air passage.
[0266] The bubbling unit 130 is received and fixed on the inside of
the medium-diameter portion 122 of the inside cylinder member 120.
The bubbling unit 130 comprises a casing 131 of a hollow cylinder
shape in which the upper and lower ends are opened and two bubbling
elements 132 provided on the casing 131. The upper portion of the
casing 131 functions as a large-diameter portion 131a and the lower
portion of the casing 131 functions as a small-diameter portion
131b. The large-diameter portion 131a is inserted into and fixed on
the inside of the medium-diameter portion 122 of the inside
cylinder portion 120 and the small diameter portion 131b is
inserted into the inside of the stem 40 in a state that there is a
space in the diametral direction. Besides, there is a space between
the bottom portion of the large-diameter portion 131a and the upper
end of the stem 40, and the spaces function as an air passage.
[0267] The bubbling element 132 is composed of a net (bubbling
member) 133 provided on one end opening of a cylinder body in which
the upper and lower ends are opened. In the bubbling element 132
arranged on the lower portion of the casing 131, the net 133 is
provided on the lower end opening of the cylinder body. Besides, in
the bubbling element 132 arranged on the upper side of the casing
131, and the net 133 is arranged on the upper end opening of the
cylinder body 132a.
[0268] On the lower-part internal surface of the small-diameter
portion 131b of the casing 131, a plurality of vertical grooves
which are extended upward from the lower end thereof are formed so
that the passages for liquid and air can be secured even when the
liquid discharge valve 70 comes into contact with the lower end of
the small-diameter portion 131b.
[0269] The outside cylinder member 110 of the pump head has a
peripheral wall portion 111 of a topped cylinder shape, and a
projection portion 112 which is projected to the side is provided
on the upper part side of the peripheral wall portion 111. The
inside of the peripheral wall portion 111 is formed as a stepped
hole in which the lower portion has a large diameter and the upper
portion has a small diameter. On the other hand, the projecting
portion 112 is formed in a cylinder shape in which an end is opened
as an approximately rectangular nozzle 113, and the nozzle 113 is
linked to the upper end of the stepped hole in the inside of the
outside cylinder member 110. Further, the shape of the nozzle 113
is not limited to the rectangle, and a circular nozzle, elliptical
nozzle and the like can be substituted for the rectangular
nozzle.
[0270] A cylinder portion 115 is extended downward from the inside
of a top board portion 114 of the outside cylinder member 110, and
only one opening 115a is opened in the cylinder portion 115.
[0271] In the outside cylinder member 110, the cylinder portion 115
is fitted fluid-tightly into the small-diameter portion 121 of the
inside cylinder member 120 in a state that it can be rotated, the
medium-diameter portion 122 of the inside cylinder member 120 is
fitted fluid-tightly into the small-diameter part of the stepped
hole of the outside cylinder member 110 in a state that it can be
rotated, and the large-diameter portion 123 of the inside cylinder
member 120 is inserted into the large-diameter part of the stepped
hole in a state that there is a space between them, and accordingly
the outside cylinder member is fitted outwardly to the inside
cylinder member 120 so that it can be rotated.
[0272] FIG. 5 is a cross section diagram of the cylinder portion
115 of the outside cylinder member 110 and the small-diameter
portion 121 of the inside cylinder member 120, and FIG. 6 is a
cross section diagram of the large-diameter portion of the stepped
hole of the outside cylinder member 110 and the large-diameter
portion 123 of the inside cylinder member 120.
[0273] As shown in FIG. 6, on the internal surface of the
large-diameter portion of the stepped hole of the outside cylinder
member 110, sets of a stopper projection 116 which is extended in
the vertical direction and a passable projection 117 are each
formed in positions which are separated one another at 180 degrees
with respect to the circumferential direction. On the other hand,
on the external surface of the large-diameter portion 123 of the
inside cylinder member 120, projections 123b which are extended in
the vertical direction are each formed in positions which are
separated one another at 180 degrees with respect to the
circumferential direction. When the outside cylinder member 110 is
rotated relatively to the inside cylinder member 117, although the
projection 123b of the inside cylinder member 120 can pass over the
passable projection 117 with a predetermined resistance, it can not
pass over the stopper projection 116, and accordingly the rotation
of the outside cylinder member 110 is limited by the stopper
projection 116.
[0274] As shown in FIG. 6, when the projection 123b is positioned
between the stopper projection 116 and the passable projection 117,
the opening 115a of the cylinder portion 115 in the outside
cylinder member 110 and the discharging hole 121a of a small
diameter in the inside cylinder member 120 are made to communicate
with one another, and the discharging hole 121b of large diameter
is closed by the peripheral surface of the cylinder portion 115.
Besides, when the outside cylinder member 110 is rotated against
the inside cylinder member 120 and the projection 123b is made to
pass over the passable projection 117 to be held onto the other
stopper projection 117 separated at 180 degrees, the opening 115a
of the cylinder portion 115 and the discharging hole 121b of large
diameter in the inside cylinder member 120 are made to communicate
with one another and the discharging hole 121a of a small diameter
is closed by the peripheral surface of the cylinder portion
115.
[0275] The skirt cylinder portion 124 of the inside cylinder member
120 is projected to the portion lower than the peripheral wall
portion 111 of the outside cylinder member 110, and the skirt
cylinder portion 124 and the peripheral wall portion 111 are
inserted into the central cylinder portion 151 of the attaching
trunk 150 so that they can be moved upward and downward. A large
number of vertical ribs 151a which are extended in the vertical
direction are formed on the internal surface of the central
cylinder portion 151, and a large number of engagement projections
124a which are each inserted between the vertical ribs 151a are
formed on the lower end of the external surface of the skirt
cylinder portion 124 in a state that they are projected to the
outside. As shown in FIG. 7, the lower end of the vertical rib 151a
tapers off as it proceeds downward and the upper end of the
engagement projection 124a tapers off as it proceeds upward so that
the vertical rib 151a and the engagement projection 124a are guided
by the respective taper surface, when the pump head 100 is ascended
from the lower part.
[0276] In the periphery of the stem 40, an annular flange portion
43 which is projected to the outside is formed near the middle in
the vertical direction and an annular rising wall 44 is provided
projectingly, upwardly on the upper surface of the flange portion
43. The internal surface of the rising wall 44 is formed on the
taper surface whose diameter is enlarged as it proceeds upward.
[0277] In the stem 40, the second piston 60 is fitted outwardly to
the space between the flange portion 43 and the pump head 100 in a
state that it can be moved upward and downward a little. The second
piston 60 is formed in a hollow cylinder shape in which the upper
and lower ends are opened, the utmost external portion is formed to
the seal cylinder portion 61 which slides on the internal surface
of the large diameter cylinder portion 22 of the cylinder member 20
air-tightly, the utmost internal portion is formed to the basic
cylinder portion 62 which is fitted outwardly to the stem 40 and
the seal cylinder portion 61 and the basic cylinder portion 62 are
connected with one another by the stepped cylinder portion 63 in
which the cross section is bent in a step form.
[0278] The upper part of the basic cylinder portion 62 is contacted
air-tightly with the internal surface of the cylinder-shaped valve
body 125 with pressure in a state that it can be slid. The air hole
64 is provided on the part in which the basic cylinder portion 62
is connected to the stepped cylinder portion 63 in a state that
they are dispersed with respect to the circumferential direction,
and the air hole 64 is opened and closed by the relative upward and
downward movement between the pump head 100 and the second piston
60. Namely, the air hole 64 is closed when the pump head 100 moves
upward and downward relatively to the second piston 60 so that the
cylinder-shaped valve body 125 of the pump head comes into contact
with the part where the basic cylinder portion 62 is connected to
the stepped cylinder portion 63, and the air hole 64 is opened when
the cylinder-shaped valve body 125 is separated from the
above-mentioned connection part.
[0279] The lower end of the basic cylinder portion 62 is brought
into contact with and separated from the internal surface of the
rising wall 44 of the stem 40 by the relative upward and downward
movement between the stem 40 and the second piston 60. In the
external surface of the stem 40, a plurality of vertical grooves 45
which are extended in the vertical direction are provided in a
region to which the basic cylinder portion 62 is fitted outwardly
in a state that they are dispersed with respect to the
circumferential direction. The vertical groove 45 is made to
communicate with the inside of the large diameter cylinder portion
22 when the lower end of the basic cylinder portion 62 is separated
from the rising wall of the stem 40, and the vertical groove 45 is
shut off from the inside of the large-diameter cylinder portion 22
when the lower end of the basic cylinder portion 62 is comes into
contact with the rising wall 44.
[0280] A second air suction valve 90 is fixed on the lower part of
the basic cylinder portion 62. The second air suction valve 90 is
provided with an annular diaphragm 91 of upward taper which is
extended outside in the diametral direction from the lower end
thereof. The diaphragm 91 has an elasticity, and operates so that
the peripheral end portion of the diaphragm 91 is brought into
contact with the lower surface of the stepped cylinder portion 63
of the second piston 60 with pressure to be sealed under normal
conditions, and the peripheral edge of the diaphragm 91 is pulled
downward by negative pressure within the large-diameter cylinder
portion 22 to be separated from the stepped cylinder portion
63.
[0281] In the attaching trunk 150, a cylinder-shaped rib 152 is
provided on the outside of the central cylinder portion 151, and
the first air suction valve 80 which seals the space between the
attaching trunk 150 and the internal surface of the large-diameter
cylinder portion 22 is fixed on the lower end of the
cylinder-shaped rib 152. A seal cylinder portion 81 of the first
air suction valve 80 in contact with the large-diameter cylinder
portion 22 is formed in a taper cylinder shape to be extended in
the diagonal upper direction, and has an elasticity. Besides, the
upper end portion of the seal cylinder portion 81 operates so that
it is pulled inside in the diametral direction by negative pressure
within the container body 1 to be separated from the internal
surface of the large-diameter cylinder portion 22.
[0282] Further, a clear cover 202 is detachably provided on the
attaching trunk 150.
[0283] Then, the operation of the container with a pump for
discharging bubbles of the embodiment 1 will be described.
[0284] FIG. 1 and FIG. 3 indicate a state that the pump head is not
yet depressed, namely, a state that the pump head is positioned at
the upper limit. In this state, the liquid suction valve 30 is
pushed up through the first piston 50 by the coil spring 39, the
lower-part valve body 31 is separated from the valve seat 24a of
the cylinder member 20, and the inside of the small-diameter
cylinder portion 24 is made to communicate with the inside of the
container body 1 through the suction pipe 201. The upper-part valve
body 35 of the liquid suction valve 30 is in contact with the valve
seat of the first piston 50 to close the upper-part opening of the
first piston 50. The lower end of the basic cylinder portion 62 of
the second piston 60 is in contact with the rising wall 44 of the
stem 40, the first air suction valve 80 is in contact with the
stepped cylinder portion 63 of the second piston 60 and the
large-diameter cylinder portion 22 of the cylinder member 20 with
pressure, and the lower end of the cylinder-shaped valve body 125
of the pump head 100 is separated from the stepped cylinder portion
63 of the second piston 60 to open the air hole 64.
[0285] As the pump head 100 is depressed from the above-mentioned
state, the stem 40 and the first piston 50 are descended together
with the pump head 100. As a result, as shown in FIG. 4, the
upper-part valve body 35 of the liquid suction valve 30 is
separated from the valve seat 52 of the first piston 50 to open the
upper-part opening of the fist piston 50. At almost the same time,
the inside of the small-diameter cylinder portion 24 is pressurized
by descending the first piston 50, the liquid suction valve 30 is
descended by liquid pressure within the small-diameter cylinder
portion 24, and the lower-part valve body 31 comes into contact
with the valve seat 24a to close the lower part opening of the
small diameter cylinder portion 24. On the other hand, the second
piston 60 is standing by frictional force between the seal cylinder
portion 61 and the large-diameter cylinder portion 22 right after
the depressing of the pump head has started. As a result of
descending of the stem 40 in the state, the lower end of the basic
cylinder portion 62 of the second piston 60 is separated from the
rising projection 44 of the stem 40, and the lower end of the
cylinder-shaped valve body 125 of the pump head 100 comes into
contact with the stepped cylinder portion 63 of the second piston
60 to close the air hole 64.
[0286] The second piston 60 is also descended together with the
pump head 100, the stem 40 and the first piston 50 after the lower
end of the cylinder-shaped valve body 125 of the pump head 100
comes into contact with the stepped cylinder portion 63 of the
second piston 60.
[0287] As the pump head 100 is descended after that, the liquid
within the small-diameter cylinder portion 24 pressurized by the
first piston 30 passes through the upper end opening of the first
piston 30 and the vertical grooves 33a and 34a of the liquid
suction valve 30 and passes through the space between the vertical
ribs 42 of the stem 40 to be pushed into the upper-part of the
upper part valve body 35. Further, the liquid pushes up the liquid
discharge valve 70 with hydraulic pressure to flow into the
vapor-liquid mixing chamber 46 (See FIG. 2). On the other hand, the
air received within the large diameter cylinder portion 22 passes
through the space between the flange portion 43 and rising
projection 44 of the stem 40 and the lower end of the basic
cylinder portion 62 of the second piston 60, passes through the
vertical groove 45 of the stem 40, passes through the vertical
groove 123a of the inside cylinder member 120 of the pump head 100,
and passes through the passage between the casing 131 of the
bubbling unit 130 and the stem 40 to flow into the vapor-liquid
mixing chamber 46.
[0288] Then, the liquid and the air are joined and mixed in the
vapor-liquid mixing chamber 46 to be delivered into the bubbling
unit 130. After that, the liquid is bubbled when it passes through
the upper and lower two nets 133 of the bubbling unit 130 to be
pushed into the cylinder portion 115 of the pump head 100 in a
foamy state. The bubble passes through the opening 115a of the
cylinder portion 115 and the small-diameter discharging hole 121a
of the small-diameter cylinder member 120 to be discharged from the
nozzle 113 of the pump head 100. FIG. 8 indicates a discharging
state of the bubbles at the moment, and the bubbles are discharged
strongly in a state that they are converged finely.
[0289] When the outside cylinder member 110 is rotated at 180
degrees against the inside cylinder member 120, the opening 115a of
the cylinder portion 115 in the outside cylinder member 110 is made
to communicate with the large-diameter discharging hole 121b of the
inside cylinder member 120 before depressing the pump head 100, and
the pump head 100 is depressed in the state, the thick bubbles are
discharged from the nozzle 113, as shown in FIG. 9. The strength of
the bubbles discharged at this case is weaker than that of the
bubbles discharged through the small-diameter discharging hole
121a.
[0290] Namely, in the container with a pump for discharging
bubbles, it is possible to select one of the large and small
discharging holes 121a and 121b to let the bubbles pass through the
discharging hole so as to change the discharging form of the
bubbles, if relative position in the circumferential direction of
the outside cylinder member 110 and the inside cylinder member 12
of the pump head 100 is selected according to circumstances.
[0291] If the finger is off from the pump head 100 after the
depressing of the pump head 100, the hydraulic pressure within the
small-diameter cylinder portion 24 and the air pressure within the
large-diameter cylinder portion 22 falls, the liquid discharge
valve 70 is brought into contact with the valve seat 41, and the
first piston 50, stem 40 and the pump head 100 are pushed up by the
elasticity of the coil spring 39.
[0292] Hereupon, the second piston 60 is standing by frictional
force between the seal cylinder portion 61 and the large-diameter
cylinder portion 22 right after the pushing up of the pump head has
begun. As a result of ascending of the stem 40 in the state, the
internal surface of the rising projection 44 of the stem 40 is
brought into contact with the lower end of the basic cylinder
portion 62 of the second piston 60 with pressure to close the space
between the inside of the large-diameter cylinder portion 22 and
the vertical groove 45 of the stem 40. At the same time, the lower
end of the cylinder-shaped valve body 125 of the pump head 100 is
separated from the stepped cylinder portion 63 of the second piston
60 to open the air hole 64.
[0293] The first piston 50, the stem 40, the second piston 60 and
the pump head 100 are ascended together, after the internal surface
of the rising projection 44 comes into contact with the lower end
of the basic cylinder portion 62.
[0294] The inside of the small-diameter cylinder potion 24 is
pressurized negatively when the first piston 50 is ascended, and
accordingly the liquid suction valve 30 is pulled up and the
lower-part valve body 31 is separated from the valve seat 24a to
make the inside of the small diameter cylinder portion 24
communicate with the inside of the container body 1. As a result,
the liquid within the container body 1 is sucked up into the
small-diameter cylinder portion 24, as the first piston 50 is
ascended.
[0295] The inside of the container body 1 is pressurized negatively
when the liquid is pumped up into the small-diameter cylinder
portion 24, and accordingly the seal cylinder portion 81 of the
first air suction valve 80 is drawn to the direction away from the
internal surface of the large diameter cylinder portion 22, and a
gap is generated between the seal cylinder portion 81 and the large
diameter cylinder portion 22.
[0296] Besides, the inside of the large-diameter cylinder portion
22 is pressurized negatively as the second piston 60 is ascended,
and accordingly the diaphragm 91 of the second air suction valve 90
is drawn downward and separated from the stepped cylinder portion
63 of the second piston 60 to generate a gap.
[0297] As a result of operating of the first air suction valve 80
and the second air suction valve 90 in the above-mentioned way, the
outside air is sucked into the attaching trunk 150 through the
space between the central cylinder portion 151 of the attaching
trunk 150 and the pump head 100. Then, part of the air passes
through the air hole 64 of the second piston 60 to get into the
large-diameter cylinder portion 22, and the other air passes
through the flange portion 21 of the cylinder member 20 to get into
the container body 1. By these actions, the pressures within the
large-diameter cylinder portion 22 and the container body 1 are
equal to the air pressure, the first piston 50 and the second
piston 60 are ascended smoothly and the liquid is pumped up into
the small-diameter cylinder portion 24 smoothly.
[0298] The container with a pump for discharging bubbles is in a
initial state shown in FIG. 1 and FIG. 3, when the pump head 100
returns to the upper limit.
[0299] [The Embodiment 2]
[0300] The container with a pump for discharging bubbles of the
embodiment 2 will be described in accordance with FIG. 10 and FIG.
11.
[0301] The basic constructions of the container with a pump for
discharging bubbles of the embodiment 2 is the same as those of the
embodiment 1, and the difference lies in a part of the construction
of the pump head 100.
[0302] In the pump head 100 in the embodiment 2, the outside
cylinder member 110 can be held in a position where the opening
115a of the outside cylinder member 110 is closed without being
connected to any one of the discharging holes 121a and 121b of the
inside cylinder member 120.
[0303] The construction will be described. FIG. 10 and FIG. 11 are
cross section diagrams corresponding to FIG. 5 and FIG. 6 of the
embodiment 1. As shown in FIG. 11, in the internal surface of the
peripheral wall portion 111 of the outside cylinder member 110, a
pair of passable projections 118a and 118b in addition to the
stopper projection 116 and passable projection 117 are provided in
a position separated at 180 degrees in the circumferential
direction one another.
[0304] When the projection 123b of the inside cylinder member 120
is positioned in a space between the passable projection 118a and
the passable projection 118b, the opening 115a of the cylinder
portion 115 of the outside cylinder-member 110 is closed by the
internal surface of the small-diameter portion 121 of the inside
cylinder member 120 without being made to communicate with any one
of the discharging holes 121a and 121b of the inside cylinder
member 120, and the discharging holes 121a and 121b are closed by
the external surface of the cylinder portion 115 at the same time,
as shown in FIG. 10.
[0305] If the opening 15a is closed in the above-mentioned way, the
inside of the inside cylinder member 120 can be prevented from
getting dry. Although it sometimes happens that part of the bubbles
are solidified in a state that it is adhered to the net 133, the
meshes of the net 133 are clogged and the formation of the bubbles
is insufficient or unstable when the pump is operated after that,
if the inside cylinder member 120 gets dry, in the embodiment 2, it
is possible to prevent the bubbles within the pump head 100 from
getting dry, and accordingly a clogging of the net 133 as a
bubbling member can be prevented and the bubbles can be formed well
and stably.
[0306] Further, if the outside cylinder member 110 is rotated

[0307] [The Embodiment 3]
[0308] The container with a pump for discharging bubbles of the
embodiment 3 will be described in accordance with FIG. 12 to FIG.
15.
[0309] FIG. 12 is a longitudinal section diagram of the container
with a pump for discharging bubbles of the embodiment 3. The
difference between the embodiment 3 and the embodiment 1 lies in
the pump head 100, and other constructions of the embodiment 3 are
the same as those of the embodiment 1. Only the difference will be
described below, and the descriptions concerning the constructions
which are the same as those of the container with a pump for
discharging bubbles of the embodiment 1 will be omitted by giving
the identical numbers to the same conditional parts.
[0310] Unlike the embodiment 1, the pump head in the embodiment 3
is not made up of two parts of the outside cylinder member and
inside cylinder member, and the parts corresponding to the members
are made up of one part in a body.
[0311] Namely, the pump head 100 has a structure in which the
outside cylinder portion 101, the inside cylinder portion 102 and
the top board portion 103 are formed in a body. The nozzle 104 is
opened in the one side upper part of the outside cylinder portion
101 and the upper part of the stem 40 is inserted into and fixed on
the lower part of the inside cylinder portion 102 and the bubbling
unit 130 is received and fixed on the upper part of the inside
cylinder portion 102. Besides, the bubbling unit 130 is linked to
the nozzle 104 through the bubbling passage 105 provided within the
pump head 100.
[0312] Besides, in the internal surface of the inside cylinder
portion 102, the vertical groove 102a corresponding to the vertical
groove 123a in the embodiment 1 is formed on the region to which
the stem 40 is fitted inwardly, and the lower end portion 102b of
the inside cylinder portion 102 has the same function as the
cylinder-shaped valve body 125 in the embodiment 1 and opens and
shuts the air hole 64 of the second piston 60.
[0313] In the embodiment 3, a nozzle attachment 300 is provided on
the nozzle 104. As shown in FIG. 13 to FIG. 15, the nozzle
attachment 300 is provided with a cylinder body portion 301 of a
rectangle cross section whose inside functions as a bubble passage
and a closing body 303 provided on the point of the cylinder body
portion 301 through a hinge portion 302 in a state that it can be
swung in the vertical direction. A discharging nozzle 304 of taper
cylinder shape is projected forward from the front-side center of
the closing body 303, and a fitting cylinder portion 305 of a
rectangle cross section which can be fitted to the cylinder body
portion 301 is projected from the back face of the closing body
303. The nozzle attachment 300 is fixed on the pump head 100 by
fitting the base of the cylinder body portion 301 into the bubble
passage 105 through the nozzle 104.
[0314] The opening area of the end opening of the discharging
nozzle 304 is sufficiently smaller than that of the cylinder body
portion 301.
[0315] In the embodiment 3, has shown in FIG. 14, the bubbles are
discharged strongly in a state that they are converged finely, if
the pump head 100 is depressed for pumping up in a state that the
closing body 303 is swung downward and the fitting cylinder portion
305 of the closing body 303 is fitted into the end of the cylinder
body portion 301.
[0316] On the other hand, as shown in FIG. 15, the thick bubbles
will be discharged from the end opening of the cylinder body
portion 301, if the pump head 100 is depressed for pumping up in a
state that the closing body 303 is swung upward and the end opening
of the cylinder body portion 301 is being exposed.
[0317] Namely, in case of the embodiment 3, it is possible to
change the discharging form of the bubbles by selecting the state
of the used closing body 300 in which it is swung downward or
upward.
[0318] Further, the cross section shape of the cylinder body
portion 301 is not limited to the rectangle and may be determined
by the shape of the nozzle 104.

[0335] The stem 40 is formed in a cylinder shape in which the upper
and lower ends are opened, and is received within the
large-diameter cylinder portion 22 and the small-diameter cylinder
portion 24 in a state that it can be moved upward and downward. The
upper part of the first piston 50 is inserted into the lower part
of the stem 40 fixedly, and the seal portion 51 is projected from
the lower part of the stem 40.
[0336] The annular valve seat 41 which is projected in a cross
section of a L-like shape is formed on the inside upper part of the
stem 40. In the inside of stem 40, the upper side of the valve seat
41 functions as a vapor-liquid mixing chamber 46, and the spherical
liquid discharge valve 70 which can be brought into contact with
and separated from the valve seat 41 is received within therein in
a state that it can be moved.
[0337] In the inside of the stem 40, a plurality of vertical ribs
42 which are extended in the vertical direction are provided on the
region from the region upper than the region to which the first
piston 30 is fixed up to the lower part of the valve seat 41, in a
state that they are dispersed with respect to the circumferential

depressing the pump head 100, the upper-part valve body 35 and the
small-diameter portion 34 of the liquid suction valve 30 can be
intruded into the inside of the vertical rib 42, and the space
between the vertical ribs 42 and the vertical groove 34a in the
small-diameter portion 34 of the liquid suction valve 30 functions
as a liquid passage.
[0338] The pump head 100 connected to the upper part of the stem 40
is provided with an outside cylinder member 110 and an inside
cylinder member 120. The inside cylinder member 120 is formed in a
hollow cylinder shape in which the upper and lower ends are opened,
and is provided with a small-diameter portion (bubble flow

the inside of the medium diameter portion 122 of the inside
cylinder member 120 and the small-diameter portion 131b is inserted
into the inside of the stem 40 in a state that there is a space in
the diametral direction. Besides, there is a space between the
bottom of the large-diameter portion 131a and the upper end of the
stem 40, and the spaces function as an air passage.
[0342] The bubbling element 132 is composed of a net (bubbling
member) 133 provided on one end opening of the cylinder body in
which the upper and lower ends are opened. In the bubbling element
132 arranged on the lower portion of the casing 131, the net 133 is
provided on the lower end opening of the cylinder body, and in the
bubbling element 132 arranged on the upper portion of the casing
131, the net 133 is provided on the upper end opening of the
cylinder body 132a.
[0343] On the lower part internal surface of the small-diameter
portion 131b of the casing 131, a plurality of vertical grooves
which are extended upward from the lower end thereof are formed so
that the passage for liquid and air can be secured even when the
liquid discharge valve 70 comes into contact with the lower end of
the small diameter portion 131b.
[0344] The outside cylinder member 110 of the pump head 100 has a
peripheral wall portion 111 of a topped cylinder shape, and the
projecting portion 112 which is projected to the side is provided
on one side upper part of the peripheral wall portion 111. The
inside of the peripheral wall portion 111 functions as a stepped
hole in which the lower portion has a large diameter and the upper
portion has a small diameter. On the other hand, the projecting
portion 112 is formed in a cylinder shape in which the end is
opened as an approximately rectangular nozzle 113, and the nozzle
113 is linked to the upper end of the stepped hole in the inside of
the outside cylinder member 110. Further, the shape of the nozzle
113 is not limited to the rectangle, and the circle nozzle,
elliptical nozzle and the like can be substituted for the
rectangular nozzle 113.
[0345] The cylinder portion (closing body) 115 is extended from the
internal surface of the top board portion 114 of the outside
cylinder member 110, and only one opening 15a is opened in the
cylinder portion 115.
[0346] In the outside cylinder member 110, the cylinder portion 115
is fitted into the small-diameter portion 121 of the inside
cylinder member 120 fluid-tightly in a state that it can be
rotated, the medium-diameter portion 122 of the inside cylinder
member 120 is fitted into the small-diameter part of the stepped
hole of the outside cylinder member 110 fluid-tightly in a state
that it can be rotated, the large-diameter portion 123 of the
inside cylinder member 120 is inserted into the large-diameter part
of the stepped hole in a state that there is a space between them,
and accordingly the outside cylinder member is fitted outwardly to
the inside cylinder member 120 so that it can be rotated.
[0347] FIG. 20 is a cross section diagram of the cylinder portion
115 of the outside cylinder member 110 and the small-diameter
portion 121 of the inside cylinder member 120, and FIG. 21 is a
cross section diagram of the large-diameter portion of the stepped
hole of the outside cylinder member 110 and the large-diameter
portion 123 of the inside cylinder member 120.
[0348] As shown in FIG. 21, in the internal surface of the
large-diameter portion of the stepped hole of the outside cylinder
member 110, sets of stopper projection 116 and passable projection
117 which are extended in the vertical direction are formed in
positions which are separated at 180 degrees one another in the
circumferential direction. On the other hand, on the external
surface of the large-diameter portion 123 of the inside cylinder
member 120, the projections 123b which are extended in the vertical
direction are each formed on the positions which are separated at
180 degrees one another in the circumferential direction.
[0349] When the outside cylinder member 110 is rotated relatively
to the inside cylinder member 120, although the projection 123b can
pass over the passable projection 117 with a predetermined
resistance, it can not pass over the stopper projection 116, and
accordingly the rotation of the outside cylinder member 110 is
limited by the stopper projection 116.
[0350] As shown in FIG. 21, when the projection 123b is positioned
between the stopper projection 116 and the passable projection 117,
the peripheral surface of the cylinder portion 115 closes the
discharging hole 121b and the peripheral surface of the
small-diameter portion 121 closes the opening 115a of the cylinder
portion 115. Then, the opening 115a of the cylinder portion 115 is
made to communicate with the discharging hole 121b, and the nozzle
113 is positioned in front of the discharging nozzle 121b in a
state that the outside cylinder member 110 is rotated against the
inside cylinder member 120, and the projection 123b is made to pass
over the passable projection 117 to be stopped on the other stopper
projection 117 which is separated at 180 degrees.
[0351] The skirt cylinder portion 124 of the inside cylinder member
120 is projected to the position lower than the peripheral wall
portion 111 of the outside cylinder member 110, and the skirt
cylinder portion 124 and the peripheral wall portion 111 are
inserted into the central cylinder portion 151 of the attaching
trunk 150 so that they can be moved upward and downward. A large
number of vertical ribs 151a which are extended in the vertical
direction are formed on the internal surface of the central
cylinder portion 151, and a large number of engagement projections
124a which are each inserted between the vertical ribs 151a are
formed on the lower end of the external surface of the skirt
cylinder portion 124 in a state that they are projected to the
outside. As shown in FIG. 22, the lower end of the vertical rib
151a tapers off as it proceeds downward, and the upper end of the
engagement projection 124a tapers off as it proceeds upward so that
the vertical rib 151a and the engagement projection 124a will be
guided by the respective taper surface, when the pump head 100 is
ascended from the lower position.
[0352] In the periphery of the stem 40, the annular flange portion
43 which is projected to the outside is formed near the middle in
the vertical direction, and an annular rising wall 44 is provided
projectingly, upwardly on the upper surface of the flange portion
43. The internal surface of the rising wall 44 is formed on the
taper surface whose diameter is enlarged as it proceeds upward.
[0353] In the stem 40, the second piston 60 is fitted outwardly to
the space between the flange portion 43 and the pump head 100 in a
state that it can be moved upward and downward a little. The second
piston 60 is formed in a hollow cylinder shape in which the upper
and lower ends are opened, the utmost external portion is formed to
the seal cylinder portion 61 which slides on the internal surface
of the large-diameter cylinder portion 22 of the cylinder member 20
air-tightly, and the utmost internal portion is formed to the basic
cylinder portion 62 which is fitted to the stem 40 outwardly so
that the seal cylinder portion 61 and the basic cylinder portion 62
are connected with one another by the stepped cylinder portion 63
whose cross section is bent in a step form.
[0354] The upper part of the basic cylinder portion 62 is brought
into contact with the internal surface of the cylinder-shaped valve
body 125 of the pump head 100 air-tightly with pressure in a state
that it can be slid. The air holes 64 are provided on the part
where the basic cylinder portion 62 is connected to the stepped
cylinder portion 63 in a state that they are dispersed with respect
to the circumferential direction, and the air holes 64 are opened
and closed by relative upward and downward movement between the
pump head 100 and the second piston 60. Namely, the air hole 64 is
closed when the pump head 100 moved upward and downward relatively
to the second piston 60 so that the cylinder-shaped valve body 125
of the pump head 100 comes into contact with the part where the
basic cylinder portion 62 is connected to the stepped cylinder
portion 63, and the air hole 64 is opened when the cylinder-shaped
valve body 125 is separated from the above-mentioned connection
part.
[0355] The lower end of the basic cylinder portion 62 is brought
into contact with and separated from the internal surface of the
rising wall 44 of the stem 40 by the relative upward and downward
movement between the stem 40 and the second piston 60. In the
external surface of the stem 40, a plurality of vertical grooves 45
which are extended in the vertical direction are provided on the
region to which the basic cylinder portion 62 is fitted outwardly
in a state that they are dispersed with respect to the
circumferential direction. The vertical groove 45 is made to
communicate with the inside of the large-diameter cylinder portion
22 when the lower end of the basic cylinder portion 62 is separated
from the rising wall 44 of the stem 40, and the vertical groove 45
is shut off from the inside of the large-diameter cylinder portion
22 when the lower end of the basic cylinder portion 62 is brought
into contact with the rising wall 44.
[0356] The second air suction valve 90 is fixed on the lower part
of the basic cylinder portion 62. The second air suction valve 90
is provided with an annular diaphragm 91 of upward taper which is
extended to the outside in the diametral direction from the lower
end thereof. The diaphragm 91 has an elasticity and operates so
that-the peripheral end portion of the diaphragm 91 comes into
contact with the lower surface of the stepped cylinder portion 63
of the second piston 60 to be sealed under normal conditions, and
the peripheral end of the diaphragm 91 is pulled downward by
negative pressurization within the large diameter cylinder portion
22 to be separated from the stepped cylinder portion 63.
[0357] In the attaching trunk 150, the cylinder-shaped rib 152 is
provided on the outside of the central cylinder portion 151, and
the first air suction valve 80 for sealing the space between the
attaching trunk 150 and the internal surface of the large-diameter
cylinder portion 22, is fixed on the lower end of the
cylinder-shaped rib 152. A seal cylinder portion 81 of the first
suction valve 80 in contact with the large-diameter cylinder
portion 22 is formed in a taper cylinder shape to be extended in
the diagonal upper direction and has an elasticity, and the upper
end portion of the seal cylinder portion 81 operates so that it is
pulled inside in the diametral direction by negative pressurization
within the container body 1, to be separated from the internal
surface of the large-diameter cylinder portion 22.
[0358] Further, the clear cover 202 is detachably provided on the
attaching trunk 150.
[0359] Then, the operation of the container with a pump for
discharging bubbles of the embodiment 4 will be described.
[0360] FIG. 16 and FIG. 18 indicate a state that the pump head is
not yet depressed, namely, a state that the pump head 100 is
positioned at the upper limit. Besides, FIG. 16 indicates a state
that the discharging hole 121b of the inside cylinder member 120 in
the pump head 100 is closed.
[0361] When the bubbles are discharged, first of all, the cover 202
is removed and the outside cylinder member 110 is rotated against
the inside cylinder member 120 so as to make the discharging hole
121b of the inside cylinder member 120 communicate with the opening
115a of the outside cylinder member 110.
[0362] In a state that the pump head 100 is not yet depressed, the
liquid suction valve 30 is pushed up by the coil spring 39 through
the first piston 50, the lower-part valve body 31 is separated from
the valve seat 24a of the cylinder-member 20, and the inside of the
small-diameter cylinder portion 24 is made to communicate with the
inside of the container body 1 through the suction pipe 201. The
upper-part valve body 35 of the liquid suction valve 30 is in
contact with the valve seat 52 of the first piston 50 to close the
upper part opening of the first piston 50. The lower end of the
basic cylinder portion 62 of the second piston 60 is in contact.
with the rising wall 44 of the stem 40, the first air suction valve
80 is in contact with the stepped cylinder portion 63 of the second
piston 60 and the large-diameter cylinder portion 22 of the
cylinder member 20 with pressure, and the lower end of the
cylinder-shaped valve body 125 of the pump head 100 is separated
from the stepped cylinder portion 63 of the second piston 60 to
open the air hole 64.
[0363] As the pump head 100 is depressed from that state, the stem
40 and the first piston 50 are descended together with the pump
head 100. As a result, as shown in FIG. 19, the upper-part valve
body 35 of the liquid suction valve 30 is separated from the valve
seat 52 of the first piston 50 to open the upper-part opening of
the first piston 50. At almost the same time, the inside of the
small-diameter cylinder portion 24 is pressurized by descending of
the first piston 50, the liquid suction valve 30 is descended by
the hydraulic pressure within the small-diameter cylinder portion
24 and the lower-part valve body 31 comes into contact with the
valve seat 24a to close the lower-part opening of the small
diameter cylinder portion 24. On the other hand, the second piston
60 is standing by the frictional force between the seal cylinder
portion 61 and the large-diameter cylinder portion 22 right after
the depressing of the pump head has been started. As a result of
descending of the stem 40 in the state, the lower end of the basic
cylinder portion 62 of the second piston 60 is separated from the
rising projection 44 of the stem 40, and the lower end of the
cylinder-shaped valve body 125 of the pump head 100 comes into
contact with the stepped cylinder portion 63 of the second piston
60 to close the air hole 64.
[0364] The second piston 60 is also descended together with the
pump head 100, the stem 40 and the first piston 50, after the lower
end of the cylinder-shaped valve body 125 of the pump head 100
comes into contact with the stepped cylinder portion 63 of the
second piston 60.
[0365] As the pump head 100 is descended after that, the liquid
within the small-diameter cylinder portion 24 pressurized by the
first piston 30 passes through the upper-end opening of the first
piston 30 and the vertical grooves 33a and 34a of the liquid
suction valve 30, and passes through the space between the vertical
ribs 42 of the stem 40 to be pushed into the upper-part of the
upper part valve body 35. Further the liquid pushes up the liquid
discharge valve 70 with the hydraulic pressure to flow into the
vapor-liquid mixing chamber 46 (See FIG. 17). On the other hand,
the air received within the large-diameter cylinder portion 22
passes through the space between the flange portion 43 and the
rising projection 44 of the stem 40 and the lower end of the basic
cylinder portion 62 in the second piston 60, passes through the
vertical groove 45 of the stem 40 and passes through the vertical
groove 123a of the inside cylinder member 120 in the pump head 100.
Further, the air passes through the passage between the casing 131
of the bubbling unit 130 and the stem 40 to flow into the
vapor-liquid mixing chamber 46.
[0366] Then, the liquid and the air are joined and mixed within the
vapor-liquid mixing chamber 46 to be delivered into the bubbling
unit 130. After that, the liquid is bubbled when it passes through
two upper and lower nets 133 of the bubbling unit 130 to be pushed
into the cylinder portion 115 of the pump head 100 in a foamy
state. The bubbles pass through the opening 115a of the cylinder
portion 115 and the discharging hole 121b of the small-diameter
portion 121 to be discharged from the nozzle 113 of the pump head
100. FIG. 23 indicates a discharging state of the bubbles at the
time.
[0367] If the finger is off from the pump head 100 after the
depressing of the pump head 100, the hydraulic pressure within the
small-diameter cylinder portion 24 and the air pressure within the
large-diameter cylinder portion 22 fall, the liquid discharge valve
comes into contact with the valve seat 41, and the first piston 50,
the stem 40 and the pump head 100 are pushed up by the elasticity
of the coil spring 39.
[0368] Hereupon, the second piston 60 is standing by the frictional
force between the seal cylinder portion 61 and large-diameter
cylinder portion 22 right after the pushing up of the stem 40 has
begun. As a result of ascending of the stem 40 in the state, the
internal surface of the rising projection 44 of the stem 40 comes
in contact with the lower end of the basic cylinder portion 62 of
the second piston 60 with pressure to close the space between the
inside of the bid diameter cylinder portion 22 and the vertical
groove 45 of the stem 40. At the same time, the lower end of the
cylinder-shaped valve body 125 of the pump head 100 is separated
from the stepped cylinder portion 63 of the second piston 60 to
open the air hole 64.
[0369] The first piston 50, the stem 40, the second piston 69 and
the pump head 100 are ascended together after the internal surface
of the rising projection 44 comes into contact with the lower end
of the basic cylinder portion 62.
[0370] The inside of the small-diameter cylinder portion 24 is
pressurized negatively when the first piston 50 is ascended, and
accordingly the liquid suction valve 30 is pulled up and the lower
part valve body 31 is separated from the valve seat 24a so as to
make the inside of the small diameter cylinder portion 24
communicate with the inside of the container body 1. As a result,
the liquid within the container body 1 is sucked up into the small
diameter cylinder portion 24 as the first piston 50 is
ascended.
[0371] The inside of the container body 1 is pressurized negatively
when the liquid is pumped up into small-diameter cylinder, and
accordingly the seal cylinder portion 81 of the first air suction
valve 80 is drawn to the direction away from the internal surface
of the large-diameter cylinder portion 22, and the gap is generated
between the seal cylinder portion 81 and the large-diameter
cylinder portion 22.
[0372] Besides, the inside of the large-diameter cylinder portion
22 is also pressurized negatively as the second piston 60 is
ascended, and accordingly the diaphragm 91 of the second air
suction valve 90 is drawn downward and separated from the stepped
cylinder portion 63 of the second piston 60 so as to generate the
gap.
[0373] As a result of operating of the first air suction valve 80
and the second air suction valve 90 in the above-mentioned way, the
outside air is sucked into the attaching trunk 150 from the space
between the central cylinder portion 151 of the attaching trunk 150
and the pump head 100. Then, part of the air passes through the air
hole 64 of the second piston 60 to get into the large-diameter
cylinder portion 22, and the other air passes through the air hole
27 of the flange portion 21 in the cylinder member 20 to get into
the container body 1. Accordingly, the pressures within the
large-diameter cylinder portion 22 and the container body 1 are
equal to the air pressure, the first piston 50 and the second
piston 60 are ascended smoothly, and the liquid is pumped up into
the small diameter cylinder portion 24 smoothly.
[0374] When the container is in a state that it is not used after
returning the pump head 100 to the upper limit position, the
outside cylinder member 110 of the pump head 100 is rotated against
the inside cylinder member 120, the discharging hole 121b of the
inside cylinder member 120 is closed by the cylinder portion 115 of
the outside cylinder member 110, and the opening 115a of the
cylinder portion 115 is closed by the small-diameter portion 121 of
the inside cylinder member 120. At that time, the projection 123b
of the outside cylinder member 110 passes over the passable
projection 117 of the inside cylinder member 120 to come into
contact with the stopper projection 116.
[0375] As mentioned hereinbefore, if the opening 115a and the
discharging-hole 121b are closed, the inside of the pump for
discharging bubbles 10 can be prevented from getting dry, and the
bubbles which are not discharged and are remaining within the pump
for discharging bubbles 10 do not get dry to be solidified.
Accordingly, the bubbles adhered to the net 133 of the bubbling
unit 130 do not get dry to be solidified, and the net 133 is not be
clogged. As a result, the bubbles can be formed securely and stably
even when the bubbles are discharged for the next time.
[0376] [Embodiment 5]
[0377] The container with a pump for discharging bubbles of the
embodiment 5 will be described in accordance with FIG. 24 and FIG.
27.
[0378] FIG. 24 is a longitudinal section diagram of the container
with a pump for discharging bubbles of the embodiment 5. The
difference between the embodiment 5 and the embodiment 4 lies in
the pump head 100, and other constructions are the same as those of
the embodiment 4. Only the difference will be described below and
the descriptions concerning the constructions which are the same as
those of the container with a pump for discharging bubbles of the
embodiment 4 will be omitted by giving the identical numbers to the
same conditional parts.
[0379] Unlike the embodiment 4, the pump head 100 in the embodiment
5 is not made up of two parts of the outside cylinder member and
the inside cylinder member, and the parts corresponding to the
members are made up of one part in a body.
[0380] Namely, the pump head 100 has a structure in which the
outside cylinder portion 101, the inside cylinder portion 102 and
the top board portion 103 are formed in a body. The nozzle 104 is
opened in the one side upper part of the-outside cylinder portion
101 and the upper part of the stem 40 is inserted into and fixed on
the lower part of the inside cylinder portion 102 and the bubbling
unit 130 is received and fixed on the upper part of the inside
cylinder portion 102. Besides, the bubbling unit 130 is connected
to the nozzle 104 through the bubbling passage 105 provided within
the pump head 100.
[0381] Besides, in the internal surface of the inside cylinder
portion 102, the vertical groove 102a corresponding to the vertical
groove 123a of the embodiment 4 is formed on the region to which
the stem 40 is fitted inwardly, and the lower end portion 102b of
the inside cylinder portion 102 has the same function as the
cylinder-shaped valve body 125 in the embodiment 4 and opens and
closes the air hole 64 of the second piston 60.
[0382] In the embodiment 5, a closing device 400 is provided on the
nozzle 104. As shown in FIG. 25 to FIG. 27, the closing device 400
is provided with a cylinder body portion 401 of a rectangle cross
section whose inside functions as a bubble passage and a closing
body 403 which is provided on the end of the cylinder body portion
401 through a hinge portion 402 in a state that it can be swung in
the vertical direction. An fitting cylinder portion 405 of a
rectangle section which can be fitted into the cylinder body
portion 401 is projected from the back face of the closing body
403. The closing unit 400 is fixed on the pump head 100 by fitting
the base of the cylinder body portion 401 into the bubbling passage
105 from the nozzle 104.
[0383] In the embodiment 5, as shown in FIG. 26, it is possible to
close the nozzle 104 and seal up the inside of the pump for
discharging bubbles 10 by swinging the closing body 403 downward
and fitting the fitting cylinder portion 405 of the closing body
403 into the end of the cylinder body portion 401. Accordingly,
also in case of the embodiment 5, the bubbles within the pump for
discharging bubbles 10 do not get dry to be solidified even when
they are not used, it is possible to prevent the net 133 from being
clogged, and the bubbles can be formed securely and stably.
[0384] Further, as shown in FIG. 27, when the bubbles are
discharged, the pump head 100 is depressed for pumping up in a
state that the closing body 403 of the closing device 400 is swung
upward so as to expose the end opening of the cylinder body portion
401. Then, the bubbles are discharged from the end opening of the
cylinder body portion 401.
[0385] Further, the cross section shape of the cylinder body
portion 401 is not limited to the rectangle, and it may be
determined by the shape of the nozzle 104.
[0386] [Embodiment 6]
[0387] The container with a pump for discharging bubbles of the
embodiment 6 will be described in accordance with FIG. 28 to FIG.
34.
[0388] The difference between the embodiment 6 and the embodiment 5
lies in the closing device 400, and other constructions are the
same as those of the embodiment 5. FIG. 28 is a longitudinal
section diagram indicating a part in which the pump head 100 is
connected to the closing device 400, and FIG. 29 is a front view
diagram of the closing device 400.
[0389] The closing device 400 of the embodiment 6 is formed in a
capped shape which covers the nozzle 104 of the pump head 100. The
closing device 400 is made up of a material having an elasticity
such as elastomer, and as shown in FIG. 29, a slit 411 is provided
on a front wall portion 410 thereof in a cross shape. The slit 411
is closed under normal conditions, and when the pump head 100 is
pushed down to discharge the bubbles into the bubble passage 105
and raise the pressure within the bubble passage 105, each part of
the front wall portion 410 divided by the slit 411 is deformed
elastically to be projected to the front. Then, the front wall
portion 410 is opened and the bubbles are discharged from the
opening.
[0390] When the depressing of the pump head 100 is stopped and the
pressure within the bubbling passage 105 is reduced, the front wall
portion 401 of the closing device 400 returns by its own elasticity
to close the front wall portion 410. As a result, also in case of
the embodiment 6, the bubbles within the pump for discharging
bubbles 10 do not get dry to be solidified and it is possible to
prevent the net 133 from clogging even when they are not used, and
the bubbles can be formed securely and stably.
[0391] FIG. 30 to FIG. 34 are the modified examples of the
embodiment 6. Namely, the shape of the front wall portion 410 of
the closing device 400 is determined according to the shape of the
nozzle 104, and as shown in FIG. 30, the shape of the front wall
portion 410 can be made into a circle, when the shape of the nozzle
104 is a circle.
[0392] Besides, the shape of the slit 411 is not limited to the
cross, the slit of a straight line shape can be substituted for the
slit 411 as shown in FIG. 31, the Y-shaped slit can be substituted
for the slit 411 as shown in FIG. 32, and eight pieces of slits can
be formed in a radial shape as shown in FIG. 33.
[0393] Further, in the form shown in FIG. 34, the closing device
400 is provided on the nozzle 104 in a state it is inserted into
the nozzle 104, the closing device 400 provided on the nozzle 400
is covered with the cover 420 having an opening 421, and the cover
420 is fitted to the pump head 100 to engage the engagement
projection 106 of the pump head 100 with the engagement concave
portion 422 of the cover 420 so that the closing device 400 is not
disconnected from the pump head 100.

connected to the stem 40 and the first piston 50 to be operated and
opens and closes the connection cylinder 25, is arranged on the
lower portion of the first piston 50.
[0403] Each of the constructions will be described in detail below.
The liquid suction valve 30, a coil spring 39 and the first piston
50 are received within the small-diameter cylinder portion 24 of
the cylinder member 20. The lower end of the liquid suction valve
30 is formed into the lower-part valve body 31 which can be brought
into contact with and separated from the valve seat 24a of a taper

[0405] In the liquid suction valve 30, the portion upper than the
engagement pins 32 is as a large-diameter portion 33, and the
small-diameter portion 34 is linked to the upper part of the
large-diameter portion 33. The vertical grooves 33a and 34a which
are extended in the vertical direction are formed on the external
surface of the large-diameter portion 33 and the peripheral surface
of the small-diameter portion 34 respectively. The upper end of the
liquid suction valve 30 linked to the small-diameter portion 34
functions as an upper part valve body of a taper cylinder shape
whose diameter gets larger as it proceeds upward.
[0406] The first piston 50 is formed in a hollow cylinder shape in
which the upper and lower ends are opened, the lower part of the
first piston 50 functions as a seal portion 51 which slides on the
internal surface of the small-diameter cylinder portion 24
fluid-tightly, and the upper part opening margin of the first

[0407] The upper part valve body 35 of the liquid suction valve 30
is projected upward from the upper-part opening of the first piston
50 and can be brought into contact with and separated from the
valve seat 52 of the first piston 50 to-open and close the upper
part opening of the first piston 50.
[0408] As shown in FIG. 35, normally, in the inside of the first
piston 50, the small-diameter portion 34 of the liquid suction
valve 30 is inserted into the space between the internal surface of
the first piston 50 and the small-diameter portion 34 in a state
that there is the enough space between them. As shown in FIG. 36,
when the stem 40 is descended by depressing the pump head 100, the
large-diameter portion 33 of the liquid suction valve 30 can be
inserted into the space between the internal surface of the first
piston 50 and the large-diameter portion 33 in a state that there
is the enough space between them, and the liquid passage is secured

cylinder member 20, and energizes the first piston 50 upward. On
the other hand, the engagement pin 32 of the liquid suction valve
30 can hold the lower end of the coil spring 39 engagedly from the
downward, and accordingly the engagement pin 32 controls the upper
limit of the liquid suction valve 30 when it is moved upward.
[0410] The stem 40 is formed in a cylinder shape in which the upper
and lower ends are opened, and is received within the
large-diameter cylinder portion 22 and the small-diameter cylinder
portion 24 in a state that it can be moved upward and downward. The
upper part of the first piston 50 is inserted into and fixed on the
lower part of the stem 40, and the seal portion 51 is projected
from the lower part of the stem 40.
[0411] The valve seat 41 of an annular shape which is projected in
a cross section of an L-like shape is formed on the inside upper
part of the stem 40. In the inside of the stem 40, the upper side
of the valve seat functions as a vapor-liquid mixing chamber 46,
and the inside of the valve seat functions as a liquid entrance to
the vapor-liquid mixing chamber. The spherical liquid discharge
valve 70 which can be brought into contact with and separated from
the valve seat 41 is received within the vapor-liquid mixing
chamber in a state that it can be moved. The liquid discharge valve
70 functions as a check valve, and comes into contact with the
valve seat 41 to prevent the liquid and air from returning to the
part lower than the valve seat 41.
[0412] In the inside of the stem 40, a plurality of vertical ribs
42 which are extended in the vertical direction are provided on the
portion from a region on which the first piston 30 is fixed, to the
lower part of the valve seat 41 in a state that they are dispersed
with respect to the circumferential direction. As shown in FIG. 36,
the upper-part valve body 35 and small-diameter portion 34 of the
liquid suction valve 30 can be inserted into the inside of the
vertical rib 42, when the pump head is depressed to make the stem
40 descend. At the time, the space between the vertical ribs 42 and
the vertical groove 34a in the small-diameter portion 34 of the
liquid suction valve 30 function as a liquid passage.
[0413] The pump head 100 linked to the upper part of the stem 40 is
formed in a topped cylinder shape in which the outside cylinder
portion 101, the inside cylinder portion 102 and the top board
portion 103 are formed in a body. The nozzle 104 is opened to the
upper-part one side of the outside cylinder portion 101, and the
nozzle 104 is linked to the inside cylinder portion 102 through the

131b, the large-diameter portion 131a is inserted into and fixed on
the inside of the inside cylinder portion 102, and the
small-diameter portion 131b is inserted into the stem 40 in a state
that there is the gap in the diametral direction. Besides, there is
the gap between the bottom of the large-diameter portion 131a and
the upper end of the stem 40, and the gaps function as an air
passage.
[0416] The bubbling element 132 is formed in a state that the net
(bubbling member) 133 is provided on one end opening of the
cylinder body in which the upper part and lower part are opened. In
the bubbling element 132 arranged on the lower end of the casing
131, the net 133 is provided on the lower end opening of the
cylinder body. In the bubbling element 132 arranged on the upper
side of the casing 131, the net 133 is provided on the upper end
opening of the cylinder body 132a.
[0417] A plurality of vertical grooves which are extended upward
from the lower end surface are formed on the lower-part internal
surface of the small diameter portion 131b of the casing 131 so
that the passage for liquid and air can be secured even when the
liquid discharge valve 70 comes into contact with the lower end of
the small diameter portion 131b.
[0418] The small-diameter portion 131b has a function as a
limitation member for controlling the upward movement region of the
liquid discharge valve 70, and as shown in FIG. 39, the distance
between the valve seat 41 and the small-diameter portion 131b is
set up so that the movement length S in which the liquid discharge
valve 70 is moved upward in the vertical direction to come into
contact with the lower end of the small-diameter portion 131b will
be from 0.1 mm and to 1.0 mm.
[0419] In the periphery of the stem, the annular flange portion 43
which is projected to the outside is formed near the center in the
vertical direction, and the annular rising wall 44 is provided
upwardly and projectingly on the upper surface of the flange
portion 43. The internal surface of the rising wall 44 is formed on
the taper surface whose diameter gets wider as it proceeds
upward.
[0420] In the stem 40, the second piston 60 is fitted outwardly to
the space between the flange portion 43 and the pump head 100 in a
state that it can be moved upward and downward a little. The second
piston 60 is formed in a hollow cylinder shape in which the upper
and lower ends are opened, the utmost outside portion is formed on
the seal cylinder portion 61 which slides on the internal surface
of the large-diameter cylinder portion 22 of the cylinder member 20
air-tightly, the utmost inside portion is formed on the basic
cylinder portion 62 to which the stem 40 is fitted outwardly, and
the seal cylinder portion 61 and the basic cylinder portion 62 are
connected with one another by the stepped cylinder portion 63 whose
cross section is bent in a step shape.
[0421] The upper part of the basic cylinder portion 62 is in
contact with the internal surface of the cylinder-shaped valve body
102b of the pump head 100 with pressure air-tightly in a state that
it can be slid. The air holes 64 are provided in the portion where
the basic cylinder portion 62 is connected to the stepped cylinder
portion 63 in a state they are dispersed with respect to the
circumferential direction, and the air holes are opened and closed
by relative upward and downward movement between the pump head 100
and the second piston 60. Namely, the air holes 64 are closed when
the pump head 100 is moved upward and downward relatively to the
second piston 60 and the cylinder-shaped valve body 102b of the
pump head 100 comes into contact with the portion where the basic
cylinder portion 62 is connected to the stepped cylinder portion
63, and the air holes 64 are opened when the cylinder-shaped valve
body 102b is separated from the above-mentioned connection
portion.
[0422] The lower end of the basic cylinder portion 62 is brought
into contact with and separated from the rising wall 44 of the stem
40 by relative upward and downward movement between the stem 40 and
the second piston 60. In the external surface of the stem 40, a
plurality of vertical grooves 45 which are extended in the vertical
direction are provided in the region to which the basic cylinder
portion 62 is fitted outwardly in a state that they are dispersed
with respect to the circumferential direction. The vertical groove
45 is linked to the inside of the large-diameter cylinder portion
22 when the lower end of the basic cylinder portion 62 is separated
from the rising wall 44 of the stem 40, and the vertical groove 45
is shut off from the inside of the large-diameter cylinder portion
22 when the lower end of the basic cylinder portion 62 comes into
contact with the rising wall 44.
[0423] The second air suction valve 90 is fixed on the lower part
of the basic cylinder portion 62. The second air suction valve 90
is provided with an annular diaphragm 91 of upward taper which is
extended in the diametral direction outside from the lower end. The
diaphragm 91 has an elasticity, and the outside marginal portion of
the diaphragm 91 is normally brought into contact with the lower
surface of the stepped cylinder portion 63 with pressure to be
sealed, and it is operated so that the outside margin of the
diaphragm 91 is pulled downward by the negative pressure within the
large-diameter cylinder portion 22 to be separated from the stepped
cylinder portion 63.
[0424] In the attaching trunk 150, the cylinder-shaped rib 152 is
provided on the outside of the central cylinder portion 151, and
the first air suction valve 80 which seals the space between the
attaching trunk 150 and the internal surface of the large-diameter
cylinder portion 22, is fixed on the lower end of the
cylinder-shaped rib 152. The seal cylinder portion 81 of the first
air suction valve 80 attached to the large-diameter cylinder
portion 22 is formed in a taper cylinder shape to be extended in
the diagonal upper direction and has an elasticity. Besides, it is
operated so that the upper end part of the seal cylinder portion 81
is pulled to the diametrical direction inside by the negative
pressure within the container body 1 to be separated from the
internal surface of the large-diameter cylinder portion 22.
[0425] Further, a clear cover 202 is detachably provided on the
attaching trunk 150.
[0426] Then, the operation of the container with a pump for
discharging bubbles in the embodiment 7 will be described.
[0427] FIG. 35 and FIG. 37 indicate a state that the pump head 100
is not yet depressed, namely, a state that the pump head is
positioned at the upper limit. First of all, the cover 202 is
removed when the bubbles are discharged.
[0428] In the state that the pump head is not yet depressed, the
liquid suction valve 30 is pushed up by the coil spring 39 through
the first piston 50, the lower-part valve body 31 is separated from
the valve seat 24a of the cylinder member 20, and the inside of the
small diameter cylinder portion 24 is made to communicate with the
inside of the container body 1 through the suction pipe 201. The
upper-part valve body 35 of the liquid suction valve 30 is in
contact with the valve seat 52 of the first piston 50 to close the
upper-part opening of the first piston 50. The lower end of the
basic cylinder portion 62 of the second piston 60 is attached to
the rising wall 44 of the stem 40, the first air suction valve 80
is in contact with the stepped cylinder portion 63 of the second
piston 60 and the large-diameter cylinder portion 22 of the
cylinder member 20 with pressure, and the lower end of the
cylinder-shaped valve body 102b of the pump head 100 is separated
from the stepped cylinder portion 63 of the second piston 60 to
open the air hole 64.
[0429] If the pump head 100 is depressed in the above-mentioned
state, the stem 40 and the first piston 50 will be descended
together with the pump head 100. As a result, as shown in FIG. 38,
the upper part valve body 35 of the liquid suction valve 30 is
separated from the valve seat 52 of the first piston 50 to open the
upper-part opening of the first piston 50. At almost the same time,
the inside of the small-diameter cylinder portion 24 is pressurized
by descending of the first piston 50, the liquid suction valve 30
is descended by the hydraulic pressure within the small-diameter
cylinder portion 24, and the lower-part valve body 31 comes into
contact with the valve seat 24a to close the lower-part opening of
the small diameter cylinder portion 24. On the other hand, the
second piston 60 is standing by the frictional force between the
seal cylinder portion 61 and the large-diameter cylinder portion 22
right after the depressing of the pump head 100 has been started.
As a result of descending the stem 40 in the state, the lower end
of the basic cylinder portion 62 of the second piston 60 is
separated from the rising projection 44 of the stem 40, and the
lower end of the cylinder-shaped valve body 102b of the pump head
100 comes into contact with the stepped cylinder portion 63 of the
second piston 60 to close the air hole 64.
[0430] The second piston 60 is descended together with the pump
head 100, the stem 40 and the first piston 50, after the lower end
of the cylinder-shaped valve body 102b of the pump head 100 comes
into contact with the stepped cylinder portion 63 of the second
piston 60.
[0431] If the pump head 100 is descended after that, the liquid
within the small-diameter portion 24 pressurized by the first
piston 30 passes through the upper-part opening of first piston 30
and the vertical grooves 33a and 34a of the liquid suction valve 30
and passes through the space between the vertical ribs 42 of the
stem 40 to be pushed out to the upper-part of the upper part valve
body 35, and pushes up the liquid discharge valve 70 with the
hydraulic pressure from the valve seat 41 to flow into the
vapor-liquid mixing chamber 46 (See FIG. 36). On the other hand,
the air received within the large-diameter cylinder portion 22
passes through the space between the flange portion 43 and rising
projection 44 of the stem 40 and the lower end of the basic
cylinder portion 62 in the second piston 60, passes through the
vertical groove 45 of the stem 40, passes through the vertical
groove 152a of the inside cylinder portion 102 in the pump head
100, and passes through the passage between the casing 131 of the
bubbling unit 130 and the stem 40 to flow into the vapor-liquid
mixing chamber 46.
[0432] Then, the liquid and air are joined and mixed in the
vapor-liquid mixing chamber to be delivered into the bubbling unit
130. After that, the liquid is bubbled when it passes through the
upper and lower two nets 133 of the bubbling unit 130 and the
bubbled liquid is pushed into the bubble passage 105 of the pump
head 100 to be discharged from the nozzle 104 of the pump head 100.
FIG. 40 indicates a discharging state of the bubbles at this
time.
[0433] When the finger is off from the pump head 100 after the
depressing of the pump head 100 has been completed, the hydraulic
pressure within the small-diameter cylinder portion 24 and the air
pressure within the large-diameter cylinder portion 22 fall, the
liquid discharge valve 70 comes into contact with to the valve seat
41, and the first piston 50, the stem 40 and the pump head 100 is
pushed upward by the elasticity of the coil spring 39.
[0434] Hereupon, the second piston 60 is standing by the frictional
force between the seal cylinder portion 61 and the large-diameter
cylinder portion 22 right after the pushing up of the stem 40 has
begun. As a result of ascending the stem 40 in the state, the
internal surface of the rising projection 44 of the stem 40 comes
into contact with the lower end of the basic cylinder portion 62 of
the second piston 60 with pressure, and the space between the
inside of the large-diameter cylinder portion 22 and the vertical
groove 45 of the stem 40 is shut off. At the same time, the lower
end of the cylinder-shaped valve body 102b of the pump head 100 is
separated from the stepped cylinder portion 63 of the second piston
60 to open the air hole 64.
[0435] The first piston 50, the stem 40, the second piston 60 and
the pump head 100 are ascended together after the internal surface
of the rising projection 44 comes into contact with the lower end
of the basic cylinder portion 62.
[0436] The inside of the small diameter cylinder portion 24 is
pressurized negatively when the first piston 50 is ascended, and
accordingly the liquid suction valve 30 is pulled up, the
lower-part valve body 31 is separated from the valve seat 24a, and
the inside of the small-diameter cylinder portion 24 is made to
communicate with the inside of the container body 1. As a result,
the liquid within the container body 1 is sucked up into the
small-diameter cylinder portion 24 as the first piston 50 is
ascended.
[0437] The inside of the container body 1 is pressurized negatively
when the liquid is pumped up into the small-diameter cylinder
portion 24, and accordingly the seal cylinder portion 81 of the
first air suction valve 80 is drawn in the direction away from the
internal surface of the large-diameter cylinder portion 22.
[0438] Besides, the inside of the large-diameter cylinder portion
22 is also pressurized negatively as the second piston 60 is
ascended, and accordingly the diaphragm 91 of the second air
suction valve 90 is drawn downward to be separated from the stepped
cylinder portion 63 of the second piston 60, and the gap is
generated.
[0439] As a result of operating of the first air suction valve 80
and the second air suction valve 90 in the above-mentioned way, the
outside air is sucked into the attaching trunk 150 from the space
between the central cylinder portion 151 of the attaching trunk 150
and the pump head 100. Then, part of the air passes through the air
hole 64 of the second piston 60 to get into the large-diameter
cylinder portion 22, and the other air passes through the air hole
27 of the flange portion 21 in the cylinder member 20 to get into
the container body 1. Accordingly, the pressures within the
large-diameter portion 22 and the container body 1 are equal to the
air pressure, the first piston 50 and the second piston 60 are
ascended smoothly, and the liquid is pumped up into the
small-diameter cylinder portion 24 smoothly.
[0440] As mentioned hereinbefore, when the finger is off from the
pump head 100 after the depressing of the pump head 100 has been
completed, the hydraulic pressure within the small-diameter
cylinder portion 24 falls, and the liquid discharge valve 70
separated upward from the valve seat 41 is descended to be brought
into contact with the valve seat 41 so as to close the liquid
entrance of the vapor-liquid mixing chamber 46.
[0441] It takes a little time to bring the liquid discharge valve
70 into contact with the valve seat 41 so as to close the liquid
entrance, and the liquid and air within the vapor-liquid mixing
chamber 46 flow into the stem 40 positioned in a portion lower than
the valve seat 41 in the meantime. The air which has flown into the
stem 40 at this moment may have a bad effect upon the pump for
discharging bubbles 10 such as deteriorating the pump efficiency
for the liquid and generating large bubbles at the beginning of
discharging bubbles, when the bubbles are discharged for the next
time.
[0442] However, in this pump for discharging bubbles 10, since the
maximum movement range of the liquid discharge valve 70 from the
state that it is in contact with the valve seat 41 to the state
that it is moved to the vertical upper direction is limited within
the range of from 0.1 mm to 1.0 mm by the small-diameter portion
131b of the bubbling unit 130, the time required for bringing the
liquid discharge valve 70 separated from the valve-seat into
contact with the valve seat 41 is reduced extremely, and the liquid
entrance of the vapor-liquid mixing chamber 46 can be closed in a
moment. Accordingly, the air that flows backward into the stem 40
from the vapor-liquid mixing chamber 46 can be removed almost
completely.
[0443] As a result, the pump efficiency for the liquid is improved,
and as shown in FIG. 40, the small bubbles are generated from the
beginning of discharging without generating the large bubbles.
[0444] Further, it has been confirmed that the particularly
preferred result can be obtained and the effect is remarkable, if
the vertical movement range from the state that the liquid
discharge valve 70 is in contact with the valve seat 41 to the
state that the liquid discharge valve 70 comes into contact with
the small diameter portion 131b of the bubbling unit 130 is within
the range of 0.2 mm-0.3 mm.
[0445] [Embodiment 8]
[0446] The container with a pump for discharging bubbles of the
embodiment 8 will be described in accordance with FIG. 41 to FIG.
48.
[0447] The container with a pump for discharging bubbles is
provided with a container body 1 in which a neck portion 2 is
provided on an upper end, a pump for discharging bubbles provided
on the neck portion 2 and an attaching trunk 150 for fixing the
pump for discharging bubbles 10 on the neck portion 2.
[0448] The pump for discharging bubbles 10 comprises a cylinder
member 20, a liquid suction valve 30, a stem 40, a first piston 50,
a second piston 60, a liquid discharge valve 70, a first air
suction valve 80, a second air suction valve 90, a pump head 100
and a bubbling unit 130.
[0449] The attaching trunk 150 comprises a peripheral wall 153
screwed on the neck portion 2 of the container body 2, a top wall
154 linked to the upper end of the peripheral wall 153 and a rising
cylinder portion 156 of a double cylinder shape which is extended
upward from the center of the top wall 154 in a state that it is
stood up. A window hole into which the pump head 100 is inserted is
opened in the center of the rising cylinder portion 156, and the
rising cylinder portion 156 guides the pump head 100 so that it can
be moved upward and downward.
[0450] The cylinder member 20 comprises a large-diameter cylinder
for air 22 which is fixed on the neck portion 2 by the attaching
trunk 150 and is inserted into the container body 2 and a small
diameter cylinder portion 24 which is extended downward in a
concentric arrangement from the lower part of the large-diameter
cylinder portion 22.
[0451] A flange portion 21 which is projected to the outside is
provided on the upper end of the large-diameter cylinder portion
22, and a fitting cylinder portion 28 is stood up from the marginal
portion of the flange portion 21. The cylinder member 20 is fixed
on the neck portion 2 by the attaching trunk 150 in a state that
the fitting cylinder portion 28 is fitted to the space between the
peripheral wall 153 of the attaching trunk 150 and an engaging
cylinder 155 and the packing 200 is made to lie in the space
between the flange portion 21 and the upper surface of the neck
portion 2.
[0452] The upper end of a suction pipe 201 is inserted into and
fixed on a connection cylinder 25 which is provided extendedly on
the lower end portion of the small diameter cylinder portion 24.
The suction pipe 201 is formed curvedly, and the lower end opening
of the suction pipe 201 is positioned in the lower-end corner
portion of the container body 2.
[0453] In the embodiment 8, the suction pipe 201 is formed in a
cylinder shape. On the other hand, as shown in
[0454] FIG. 44, in the connection cylinder 25, the upper-half
internal surface of the connection cylinder 25 is formed in a cross
section square shape, the suction pipe 201 which has been fixed on
the connection cylinder 25 once is not rotated against the
connection cylinder 25 when the pump for discharging bubbles 10 is
provided on the container body 1 and so on, and as shown in FIG.
45, the lower part of the connection cylinder 25 is formed in a
cross section of circle so that the suction pipe 201 can be easily
provided on the connection cylinder 25 even if the upper internal
surface of the connection cylinder 25 is formed in a square
shape.
[0455] In the embodiment 8, a rotation-preventing mechanism is
provided on the region where the attaching trunk 150 is fitted to
the cylinder member 20. The rotation-preventing mechanism is made
up of a large number of vertical ribs 28a provided on the periphery
of the fitting cylinder portion 28 of the cylinder member 20 and a
large number of vertical ribs 153a provided on the internal surface
upper end portion of the peripheral wall 153 of the attaching trunk
150. The mutual rotation of the attaching trunk 150 and the
cylinder member 20 can be prevented by making the vertical ribs 28a
and the vertical ribs 153a engage with one another.
[0456] If the rotation-preventing mechanism is provided in the
above-mentioned way, the mispositioning of the attaching trunk 150
and the cylinder member 20 by the tightening torque can be
prevented when the attaching trunk 150 is tightened into the neck
portion 2 of the container body 1.
[0457] A plate-shaped projection 22a for indicating a position of
an air hole 27 mentioned later is provided projectingly on the
predetermined position in the lower surface of the large-diameter
cylinder portion 22 so that the attaching trunk 150 can be provided
on the proper position of the cylinder member 20 mechanically.
[0458] The stem 40 and the pump head 100 are provided on the
cylinder member 20 in a state they can be moved upward and downward
freely and they are energized upward. The second piston 60 fitted
into the large-diameter cylinder portion 22 and the first piston 50
fitted into the small-diameter cylinder portion 24 are provided on
the stem 40.
[0459] In the container of the present invention, the internal
bubble-discharging mechanism is operated so as to discharge the
bubbles from the nozzle 107 of the pump head 100 by moving the pump
head upward and downward.
[0460] The circular first piston 50 fitted to the upper part of the
small-diameter cylinder portion 24 is provided on the lower end of
the stem 40 in a state that the lower part of the first piston 50
is projected from the lower end of the stem 40. The stem 40 is
energized upward by the coil spring 39 lying in the space between
the first piston 50 and the lower end portion of the small-diameter
cylinder portion 24 all the time, and accordingly the pump head 100
is also energized upward all the time. Besides, the liquid
discharge valve 70 is provided on the upper part of the inside of
the stem 40.
[0461] The liquid suction valve 30 is received within the
small-diameter cylinder portion 24. The upper end portion of the
liquid suction valve 30 functions as an upper-part valve body 35
which is formed in an upward skirt shape, and the upper part valve
body 35 comes into contact with the valve seat 52 provided on the
upper-end internal surface of the first piston 50 to shut off
between the upper part and lower part of the stem 40 normally, and
the upper part valve body 35 is separated from the valve seat 52 to
make the upper-part and the lower part communicate with one another
by depressing the pump head 100. Accordingly, the inconveniences
such as leakage of the liquid from the nozzle 107 can be prevented
to the utmost, even if the liquid discharge valve 70 is
mispositioned when the container is upset by mistake.
[0462] The engagement pin 32 provided projectingly from the lower
part periphery of the liquid suction valve 30 is engaged to the
space among the plurality of vertical ribs 26 provided on the
lower-end internal surface of the small-diameter cylinder portion
24 in a state that it can be moved upward and downward, and the
lower end surface of the coil spring 39 is in contact with and held
engagedly on the upper surface of each vertical rib 26.
[0463] The lower end of the liquid suction valve 30 is formed on
the lower-part valve body 31 so that the lower-part valve body 31
can be brought into contact with and separated from the bottom face
portion of the small-diameter cylinder portion 24. Namely, if the
pump head 100 is depressed, the upper-part valve body 35 is fitted
to the internal surface of the descending stem 40 to push down the
liquid suction valve 30, and the lower-part valve body 31 comes
into contact with the bottom face portion of the small-diameter
cylinder portion 24 to shut off between the inside of the suction
pipe 201 and the inside of the small-diameter cylinder portion
24.
[0464] The pump head 100 has a casing of a cylinder shape in which
the upper end of the outside cylinder portion 101 is closed by the
top board portion 103 and the lower end of the outside cylinder
portion 101 is opened, and the projecting portion 112 of a cylinder
shape is extended horizontally from the upper end of the inside
cylinder portion 102 provided on the center of the casing in a
body. The front end of the projecting portion 112 is projected to
the position outer than the outside cylinder portion 101 to
function as a nozzle 107.
[0465] The upper end portion of the stem 40 is fitted to and fixed
on the lower part of the inside cylinder portion 102 so that the
stem 40 and the pump head 100 are moved upward and downward
together. The inside of the inside cylinder portion 102 functions
as a bubble passage 105 which is extended to the discharging hole
at the end of the nozzle 107 from the inside of the stem 40.
[0466] The container is provided with a directional control
mechanism for directing the lower part opening of the suction pipe
201 and the nozzle 107 of the pump head 100 to the same direction
all the time when the pump head 100 is moved upward and
downward.
[0467] The directional control mechanism in the embodiment 8
comprises a concave groove 157 in the vertical direction provided
on the internal surface of the rising cylinder portion 156 of the
attaching trunk 150 and a vertical projection 110a provided on the
front face predetermined position of the outside cylinder portion
101 of the pump head 100, and the vertical projection 110a is
engaged to the concave groove 157 in a state that it can be moved
upward and downward.
[0468] Accordingly, the pump head 100 can be moved upward and
downward while directing the discharging hole at the point of the
nozzle 107 and the lower opening of the suction pipe 201 to the
same direction all the time. The directional control mechanism
comprising the concave groove 157 and the vertical projection 101a
as mentioned above can be easily structured and can be easily
manufactured.
[0469] The above-mentioned directional control mechanism is not
limited to the directional control mechanism in the embodiment 8,
and for instance, a directional control mechanism in which the
window hole of the central part of the rising cylinder portion 156
of the attaching trunk 150 is formed into a non-circle window hole
and the peripheral lower part of the pump head 100 is formed like
the non-circle window hole, can be substituted for the directional
control mechanism in the embodiment 8. If the directional control
mechanism is structured in the above-mentioned way, the appearance
of the container is improved because the extra projection and
concave groove are not exposed to the pump head 100, and the
individualization of the container can be planned due to the
non-circle pump head 100.
[0470] To put it concretely, a directional control mechanism in
which the window hole of the attaching trunk 150 is formed in a
square shape and the lower part of the outside cylinder portion 101
of the pump head 100 is formed into a square outside cylinder
portion 101A like the above-mentioned square window hole as shown
in FIG. 47 can be substituted for the directional control mechanism
in the embodiment 8, or the directional control mechanism in which
the window hole of the attaching trunk 150 is formed into an
elliptical window hole and the lower part of the outside cylinder
portion 101 is formed into an elliptical outside cylinder portion
101B like the above-mentioned elliptical window hole as shown in
FIG. 48 can be substituted for the directional control mechanism in
the embodiment 8.
[0471] A bubbling unit 130 is provided within the bubble passage
105 in the portion upper than the liquid discharge valve 70. The
bubbling unit 130 is provided with a net woven with polyester fiber
and the like and it is constructed so that the vapor-liquid mixed
solution is bubbled to be formed into the bubbles when the
vapor-liquid mixed solution passes through the net. In the
embodiment 8, the bubbling portion 130 in which two cylinder bodies
whose upper and lower ends are provided with the net are arranged
vertically, is fitted to the inside cylinder portion 102 of the
pump head 10 fixedly.
[0472] A unit for regulating bubbles 139 having a net is provided
within the projecting portion 112 in the downstream position of the
bubbling unit 130. The unit for regulating bubbles 139 functions to
equalize almost the bubbles which have been bubbled once by the
upstream bubbling unit 130.
[0473] An air passage 102c for supplying the stem 40 with the air
within an air pressurizing chamber A mentioned later is provided on
the periphery of the stem 40. One end of the air passage 102c is
opened to the internal surface of the stem 40 in the space between
the liquid discharge valve 70 and the bubbling unit 130, and the
other end of the air passage 102c is opened to the concave portion
102d formed in an annular shape on the lower part periphery of the
inside cylinder portion 102.
[0474] The second piston 60 is formed separating from the stem 40.
Besides, in the second piston 60, the seal cylinder portion 61
fitted to the internal surface of the large-diameter cylinder
portion 22 is provided on the peripheral portion, and the basic
cylinder portion 62 fitted to the outside of the stem 40 is
provided on the inside portion.
[0475] The upper end of the basic cylinder portion 62 is fitted
air-tightly to the outside surface of the concave portion 102d in a
state that it can be moved upward and downward, and the lower end
of the basic cylinder portion 62 can be brought into contact
air-tightly with the upper surface of the flange portion 43
provided on the stem 40. The air pressurizing chamber A is
constructed by the second piston 60 and the large-diameter cylinder
portion 22.
[0476] At the utmost ascending position of the stem 40 and the pump
head 100 pushed up by the coil spring 39, the lower end of the
basic cylinder portion 62 is brought into contact air-tightly with
the upper surface of the flange portion 43 to shut off between the
inside of the large-diameter cylinder portion 22 and the inside of
the air passage 102c.
[0477] A plurality of air holes 64 are provided on the inside
marginal portion of the second piston 60 in a state that they are
dispersed with respect to the circumferential direction, and an
annular valve cylinder 65 is provided on the outside of the air
hole 64 in a state that it is stood up. The valve body 65 can be
brought into contact air-tightly with the lower-end peripheral
portion of the inside cylinder portion 102.
[0478] The second air suction valve 90 is fitted to the basic
cylinder portion 62 positioned in a portion lower than the air hole
64, and the diaphragm 91 of doughnut board shape provided on the
second air suction valve 90 is constructed so that it can close the
air hole 64 air-tightly. Namely, the dual seal structure is formed
by the valve cylinder 65 and the diaphragm 91.
[0479] If the pump head 100 is depressed in the above-mentioned
state, the second piston 60 is ascended relatively to the stem 40
to make the inside of the air pressurizing chamber A and the inside
of the stem 40 communicate with one another through the air passage
102c. On the other hand, when the pump head 100 is ascended, the
lower end of the basic cylinder portion 62 is brought into contact
air-tightly with the upper surface of the flange portion 43 to
close the air passage 102c and open the second air suction valve 90
so that the outside air is introduced into the large-diameter
cylinder portion 22.
[0480] The large-diameter cylinder portion 22 is provided with an
air hole 27 for introducing the outside air into the container body
1. The air hole 27 is arranged in a position opposite to the
opening direction of the nozzle 107 of the pump head 100. In the
embodiment 8, the air hole 27 is opened in the flange 13 of the
rear of the large-diameter cylinder portion 22.
[0481] The first air suction valve 80 for opening and closing the
air hole 27 is provided on the attaching trunk 150. The first air
suction valve 80 comprises an annular basic portion and two seal
cylinder portions 81 and 82 which are extended in the vertical
direction from the annular basic portion. The annular basic portion
is fitted and fixed on the periphery of the cylinder-shaped rib 152
which is extended downward from the lower surface of the top wall
154 of the attaching trunk 150.
[0482] The seal cylinder portion 81 is extended in a skirt shape in
the diagonal upper direction from the peripheral lower portion of
the annular basic portion, and the outside marginal portion of the
seal cylinder portion 81 is brought into contact air-tightly with
the inside upper end portion of the large-diameter cylinder portion
22.
[0483] The seal cylinder portion 82 is extended in a skirt shape in
the diagonal lower direction from the internal surface lower part
of the annular basic portion, and the outside marginal portion of
the seal cylinder portion 82 is brought into contact air-tightly
with the outside surface of the vertical wall part of the second
piston 60. A dual seal structure is formed by the seal cylinder
portions 81 and 82.
[0484] Further, it is preferable that each of the members is formed
from synthetic resin, elastomer and the like.
[0485] Then, the operation of the embodiment 8 will be
described.
[0486] When the pump head 100 is depressed, the lower part valve
body 31 is closed to pressurize the inside of the small diameter
cylinder portion 24, and the liquid within the small-diameter
cylinder portion 24 pushes up the liquid discharge valve 70 to be
introduced into the bubble passage 105. At the same time, the air
pressurizing chamber A is pressurized and the second piston 60 is
ascended relatively to the stem 40 to open the seal of the lower
end of the basic cylinder portion 62, the pressurized air within
the air pressurizing chamber A passes through the air passage 102c
to be introduced into the bubble passage 105, and the vapor-liquid
mixed solution which has been mixed hereupon passes through the
bubbling unit 130 to be bubbled, then passes through the unit for
regulating bubbles 139 to be discharged from the end of the nozzle
107 in a foamy state.
[0487] Then, when the pump head 100 is released from the
depressing, the stem 40 and the pump head 100 are ascended by the
action of the coil spring 39 and the inside of the small-diameter
cylinder portion 24 is pressurized negatively, and accordingly the
liquid discharge valve 70 is closed, the suction valve 55 is
opened, and the liquid within the container body 2 is sucked into
the small diameter cylinder portion 24. On the other hand, the
second piston 60 is descended relatively to the stem 40 to seal the
lower end of the basic cylinder portion 62 and close the air
passage 102c, and the outside air is introduced into the air
pressurizing chamber A which has been pressurized negatively
through the second air suction valve 90.
[0488] At the same time, the first air suction valve 80 is opened
and the outside air is introduced into the container body 1 from
the air hole 27, since the inside of the container body 1 is
pressurized negatively due to the fact that the liquid within the
container body 1 is sucked into the small diameter cylinder portion
24.
[0489] The air exists all the time in the air hole 27 portion and
the portion is never submerged in the liquid, because the opening
of the nozzle 107 and the opening of the suction pipe 201 are in
the same direction all the time, and the air hole 27 is in a
position opposite to the opening direction of the nozzle 107, when
the bubbles are discharged.
[0490] Accordingly, the introduced outside air never gets to the
liquid surface through the inside of the liquid. As a result, the
inconvenience that the upper part of the liquid surface is filled
with the bubbles and so on will never occur.
[0491] The liquid within the container body 1 can be discharged
entirely, because the lower end opening of the suction pipe 201 is
directed to the same direction as the opening direction of the
nozzle 107 and is positioned in the lower end portion within the
container body 1.
[0492] [The Embodiment 9]

[0504] Besides, the second piston 60 fitted into the large-diameter
cylinder portion 22 and the first piston 50 fitted into the
small-diameter cylinder portion 24 are provided on the stem 40. The
second piston 60 is provided in a state that it can be moved upward
and downward only a little stroke relative to the stem 40.
[0505] The first piston 50 is provided on the stem 40 in a state
that the cylinder portion 53 is fitted to the lower end inside of
the stem 40, and the seal portion 51 is projected from the lower
end of the stem 40. The stem 40 is energized upward all the time by
the coil spring 39 which is kept in the space between the first

small diameter cylinder portion 24, and accordingly the pump head
100 is also energized upward all the time.
[0506] The liquid discharge valve 70 is provided on the upper part
within the stem 40, the annular flange portion 43 which is
projected to the outside is provided on the middle part of the stem
40, and the annular rising wall 44 is stood up from the periphery
of the flange portion 43.
[0507] In the pump head 100, the fitting cylinder 108 is extended
downward from the peripheral portion of the top board portion 103,
the nozzle 107 in which the basic end is opened on the upper end
internal surface of the fitting cylinder 108 is extended in the
horizontal direction, and the end portion of the nozzle 107 is
projected to the outside. In the embodiment 9, although the fitting
cylinder 108 is formed into a dual cylinder, a single cylinder may
be substituted for the fitting cylinder 108.
[0508] The lower part of the fitting cylinder 108 is inserted into
the central cylinder portion 151 of the attaching trunk 150 in a
state that it can be slid. The lower part inside of the fitting
cylinder 108 is formed on the large inside diameter portion, and
the upper end portion of the stem 40 is fitted to the lower half of
the upper cylinder part. A plurality of vertical grooves 108a are
provided on the internal surface of the part to which the stem 40
is fitted, and the upper end of the vertical groove 108a is
arranged in a position higher than the upper end surface of the
stem 40.
[0509] An opening cylinder 107a is fitted to the end of the nozzle
107, and a net 107b for regulating bubbles is provided extendedly
on the internal end of the opening cylinder 107a.
[0510] The casing 131 which has been inserted into the upper end
portion of the stem 40 and the lower part of which is made to a
small-diameter portion 131b is fitted to the upper part inside of
the above-mentioned fitting cylinder 108. In the casing 131, the
length of the part to which the bubbling element 132 is fitted is
set up in the length to which a plurality of bubbling elements 132
can be fitted in a state that they are piled upward and
downward.
[0511] In the small-diameter portion 131b inserted into the upper
end portion of the stem 40, an inward flange is provided on the
lower end, and a blocking piece 131c is extended downward from the
inward flange. The blocking piece 131c prevents the liquid
discharge valve 70 from closing the hole 134 of the inward flange,
when the liquid discharge valve 70 is pushed up by the liquid
flowing into the casing 131 from the inside of the stem 40.
[0512] The space between the inward flange and the liquid discharge
valve 70 functions as a vapor-liquid mixing chamber 46, and the
liquid which has passed through the liquid discharge valve 70 and
the high-pressure air which has passed through the vertical groove
108a and the space between the upper part internal surface of the
stem 40 and the outer surface of the small-diameter portion 131b to
be flown out are mixed in the vapor-liquid mixing chamber 46.
[0513] Further, the casing 131 is not always required, and the
bubbling element 132 can be fitted to the upper part inside of the
fitting cylinder 108 directly.
[0514] The bubbling element 132 is structured such that the net 133
is provided extendedly on the upper surface of the short cylinder
135. The outside diameter of the short cylinder 135 has the size in
which the short cylinder 135 can be fitted fixedly into the
internal surface of the casing 131. In the container shown in FIG.
49 to FIG. 51, the bubbling element arranged on the lower side is
provided in a state it is inverted, and the bubbling element 132
arranged on the upper side is provided in a state that it is
erected.
[0515] Besides, in one shown in FIG. 52, only one inverted bubbling
element 132 is fitted into the lower part of the casing 131. In one
shown in FIG. 53, only one erected bubbling element 132 is fitted
into the upper part of the casing 131.
[0516] The second piston 60 comprises a basic cylinder portion 62
fitted to the upper part external surface of the stem 40 in a state
that it can be slid, a seal cylinder portion 61 fitted to the
internal surface of the large-diameter cylinder portion 22 in a
state that it can be slid and a stepped cylinder portion 63 which
connects the basic cylinder portion 62 to the seal cylinder portion
61. The stepped cylinder portion 63 is formed in a step shape in
which the basic cylinder portion 62 side is high and the seal
cylinder portion 61 side is low.
[0517] In the stepped cylinder portion 63, a plurality of air holes
64 are provided in the portion adjacent to the basic cylinder
portion 62. The upper portion of the basic cylinder portion 62
functions as a thin-wall elastic portion which is enlarged to a
little upper outside, and the end of the basic cylinder portion 62
is brought into contact air-tightly with the lower part internal
surface with pressure.
[0518] A plurality of projections 66 are provided on the internal
surface of the vertical cylinder part in the stepped cylinder
portion 63. In the stepped cylinder portion 63, an engaging
cylinder 67 is provided from the upper horizontal board shape
portion in a state that it is stood up so as to open a little gap
in the space between the engaging cylinder 67 and the basic
cylinder portion 62, and the air hole 64 is provided on the
horizontal board shape portion positioned in the gap.
[0519] The second piston 20 is provided on the stem 40 in a state
that it can be moved upward and downward only a little stroke in
which the position where the lower end of the basic cylinder
portion 62 is fitted to the internal surface in the rising wall 44
of the flange portion 43 of the stem 40 as shown in FIG. 49 is the
lower limit, and the position where the lower end of the inside
cylinder portion 108b of the fitting cylinder 108 is fitted
air-tightly to the space between the basic cylinder portion 62 of
the second piston 60 and the engaging cylinder 67 to seal the air
hole 64 like FIG. 50 is the upper limit.
[0520] A plurality of vertical grooves 45 are provided on the
external surface of the stem 40 within the portion in which the
basic cylinder portion 62 of the second piston 60 is slid in the
range that it is moved upward and downward only a little stroke,
and the communication between the lower end of the vertical groove
45 and the inside of the large diameter cylinder portion 22 is shut
off by bringing the lower end of the basic cylinder portion 62 into
contact with the flange portion 43, when the second piston 60 is
descended to the lower limit for the stem 40.
[0521] The second air suction valve 90 is fitted to the lower half
external surface of the basic cylinder portion 62 of the second
piston 60. The second air suction valve 90 comprises a short
cylinder 92 fitted to the lower half external surface of the basic
cylinder portion 62 and a thin-wall diaphragm 91 having an
elasticity which is projected annularly to the diagonal upper
outside from the lower end of the short cylinder 92.
[0522] The end portion of the diaphragm 91 is formed in a thick
wall portion, and the upper surface of the thick wall portion is in
contact with the lower surface of the middle horizontal board shape
portion in the stepped cylinder portion 63 of the piston 60 with
pressure.
[0523] In the second air suction valve 90 structured in the
above-mentioned way, the elastic deformation of the diaphragm 91
can be easily made, and the second air suction valve 90 can be
opened and closed securely, because the thick wall portion is
provided on the end portion of the diaphragm 91.
[0524] As shown in FIG. 50, the second air suction valve 90 is
descended in a state that it is closed to pressurize the inside of
the large-diameter cylinder portion 22 when the stem 40 is
descended. If the second air suction valve 90 is provided in the
position opposite to FIG. 50 (namely, in a state that it is
inverted) due to any mistakes, it is impossible to pressurize the
inside of the large-diameter cylinder portion 22 and the
pressurization is irresponsive, and accordingly the trouble which
has occurred in the second air suction valve 90 can be discovered
without delay, because the diaphragm 91 is in contact with the
projecting portion 63 in the stepped cylinder portion 63 of the
second piston 60 so that the valve can not be closed by the second
air suction valve 90.
[0525] The first air suction valve 80 is provided on the
cylinder-shaped rib 152 of the attaching trunk 150. The first air
suction valve 80 comprises a cylinder portion 83 fitted to the
external surface of the cylinder-shaped rib 152 of the attaching
trunk 150, a seal cylinder portion 81 which is extended in a
reverse-skirt shape to the diagonal upper outside and has an
elasticity and a seal cylinder portion 82 which is extended
downward from the lower part internal surface of the cylinder
portion 83.
[0526] A little gap is formed in the space between the cylinder
portion 83 and the peripheral wall internal surface of the
large-diameter cylinder portion 22. The end portion of the seal
cylinder portion is in contact with the upper internal surface of
the peripheral wall of the large-diameter cylinder portion 22 with
pressure. As shown in FIG. 49, in the seal cylinder portion 82, the
internal surface of the seal cylinder portion 82 is brought into
contact water-tightly with the external surface of the vertical
cylinder portion in the stepped cylinder portion 63 of the second
piston 60 with pressure when the stem 40 is at the upper limit.
[0527] There is not any possibilities that the first air suction
valve 80 falls off from the cylinder-shaped rib 152 by the
high-pressure air, even if the air within the container body
high-pressurized by temperature rise and the like passes through
the air hole 27 of the flange portion 21 of the cylinder member 20
to get into the upper part of the large-diameter cylinder portion
22, because the first air suction valve 80 is structured in the
above-mentioned way.
[0528] The liquid suction valve 30 is received within the
small-diameter cylinder portion 24 to insert the upper part of the
liquid suction valve 30 into the lower part of the stem 40.
[0529] A plurality of engagement pins 32 are projected in a portion
of a little upper from the lower end of the liquid suction valve
30, and the engagement pins 32 are fitted to the space among the
vertical ribs 26 provided vertically on the lower part internal
surface of the small-diameter cylinder portion 24 in a state that
they can be moved upward and downward. The lower end of the liquid
suction valve 30 functions as a lower-part valve body 31, and the
lower part valve body 31 closes the liquid suction hole of the
small diameter cylinder portion 24, when the liquid suction valve
30 is descended.
[0530] The upper end of the liquid suction valve 30 functions as an
upper-part valve body 35, and the upper part valve body 35 is held
by the internal surface of the projections provided vertically on
the internal surface of the stem 40 and can be slid to the internal
surface of the projections. Accordingly, when the stem 40 is
descended, the stem 40 and the liquid suction valve 30 are
descended together in the beginning. After the lower-part valve
body 31 of the liquid suction valve 30 comes into contact with the
lower end of the small diameter cylinder portion 24 to close the
liquid suction valve hole, the liquid suction valve 30 is stopped
and the stem 40 continues to be descended.
[0531] On the other hand, when the stem 40 is ascended, although
the liquid suction valve 30 is ascended with the stem 40 in the
beginning, the liquid suction valve 30 is stopped by contact of the
engagement pin 32 with the lower surface of the coil spring 39 and
the stem 40 continues to be ascended.
[0532] In the container structured in the above-mentioned way, the
bubble whose diameter is suitable for the use can be bubbled easily
by changing the number of the bubbling elements 132 to be provided
and the direction of the bubbling element 132 and so on, because
the net 133 is provided extendedly on the upper end of the short
cylinder 135 to form the bubbling element 132, the cylinder hole
portion (casing 131) for fitting the bubbling element 132 is formed
long in the vertical direction, and the cylinder hole portion is
set up in the length into which a plurality of bubbling elements
132 can be fitted in a line so as to fit a single or a plurality of
bubbling elements 132 to the cylinder hole part.
[0533] According to an experiment, the bubbling of the fine and
equalized bubbles could be obtained, when one bubbling element 132
in which a net 133 was provided extendedly on the upper end of the
short cylinder 135 was fitted to the upper part, and one similar
bubbling element 132 was fitted to the lower part-in a state that
it was inverted within the casing 131, respectively as shown in
FIG. 49 to FIG. 51. The bubbles of medium diameter could be
bubbled, when only one bubbling element 132 in which the net 133
was provided on the lower end of the short cylinder 83 was fitted
to the lower part of the casing 131 as shown in FIG. 52, and the
bubbles of large-diameter could be bubbled when only one bubbling
element 132 in which the net was provided extendedly on the upper
end of the short cylinder 83 was fitted to the upper part of the
casing 131 as shown in FIG. 53.
[0534] Besides, the diameter of the bubbles could be changed
gradually within the range of the diameter of the bubbles in the
case shown in FIG. 52 to the diameter of the bubbles in the case
shown in FIG. 53, when the fitting position of the bubbling element
132 of FIG. 52 was moved upward in order and the fitting position
of the bubbling element 132 of FIG. 53 was moved downward in
order.
[0535] The diameter of the bubbles which were discharged could be
further shortened a little and could be equalized, when the mouth
cylinder 107a was fitted into the end of the nozzle 107 and the net
107b was provided extendedly on the mouth cylinder 107a.

[0554] In the casing 131, the length of the part to which the
bubbling element 132 is fitted is set up in the length to which a
plurality of bubbling elements can be fitted in a state that they
are piled upward and downward. In the small-diameter portion 131b
inserted into the upper end portion of the stem 40, an inward
flange is provided on the lower end and a blocking piece 131c is
extended downward from the inward flange.
[0555] The blocking piece 131c prevents the liquid discharge valve
70 from closing a hole 134 of the inward flange, when the liquid
discharge valve 70 is pushed up by the liquid flowing into the
casing 131 from the inside of the stem 40.
[0556] The space between the inward flange and the liquid discharge
valve 70 functions as a vapor-liquid mixing chamber 46. In the
vapor-liquid mixing chamber 46, the liquid which has passed through
the liquid discharge valve 70 is mixed with the high pressure air
which has passed through the vertical groove 108a and the space
between the upper part internal surface of the stem 40 and the
external surface of the small diameter portion 131b.
[0557] Further, the casing 131 is not always required, and the
bubbling element 132 can be fitted to upper part inside of the
fitting cylinder 108 directly.
[0558] The bubbling element 132 is structured such that the net 133
is provided extendedly on the upper end of the short cylinder 135.
The outside diameter of the short cylinder 135 is made to the size
which can be inserted fixedly into the internal surface of the
casing 131. In the container shown in FIG. 54 and FIG. 55, the
bubbling element 132 arranged on the lower side is provided in a
state that it is inverted and the bubbling element 132 arranged on
the upper side is provided in a state that it is erected.
[0559] Further, although the illustration is omitted, the container
can be structured such that only one inverted bubbling element 132
is fitted into the lower part of the casing 131, or the container
can be structured such that only one erected bubbling element 132
is fitted into the upper part of the casing 131.
[0560] As mentioned hereinbefore, the container is structured such
that a single or a plurality of bubbling elements 132 can be fitted
to the casing 131 which is a bubbling member fitting portion.
[0561] The second piston 60 comprises a basic cylinder portion 62
fitted to the upper-part external surface of the stem 40 in a state
that it can be slid, a seal cylinder portion 61 fitted to the
internal surface of the large-diameter cylinder portion 22 in a
state that it can be slid and a stepped cylinder portion 63 which
connects the basic cylinder portion 62 to the seal cylinder portion
61. The stepped cylinder portion 63 is formed in a step shape in
which the basic cylinder portion 62 side is high and the seal
cylinder portion 61 side is low.
[0562] In the stepped cylinder portion 63, a plurality of air holes
64 are provided on the part adjacent to the basic cylinder portion
62. The upper end of the basic cylinder portion 62 functions as a
thin-wall elastic portion which is enlarged to a little upper
outside, and the end of the basic cylinder portion 62 is brought
into contact air-tightly with the lower part internal surface of
the fitting cylinder 108 with pressure.
[0563] In the stepped cylinder portion 63, a plurality of
projections 66 are provided on the internal surface of the vertical
cylinder part. In the stepped cylinder portion 63, the engaging
cylinder 67 is provided from the upper horizontal board shape
portion in a state that it is stood up and a little gap is opened
in a space between the basic cylinder portion 62 and the engaging
cylinder 67, and the air hole 64 is provided on the horizontal
board shape portion positioned on the above-mentioned gap.
[0564] The second piston 60 is provided on the stem 40 in a state
that it can be moved upward and downward only a little stroke in
which the position where the lower end of the basic cylinder
portion 62 is fitted to the internal surface of the rising wall 44
of the flange portion 43 in the stem 40 as shown in FIG. 54 is a
lower limit, and the position where the lower end of the fitting
cylinder 108 is fitted air-tightly to the space between the basic
cylinder portion 62 of the second piston 60 and the engaging
cylinder 67 to close the air hole 64 closely is an upper limit.
[0565] A plurality of vertical grooves 45 are provided on the
external surface of the stem 40 of the part in which the basic
cylinder portion 62 of the second piston 60 can be slid, within the
range in which it can be moved upward and downward only a little
stroke, and when the second piston 60 is descended to the lower
limit for the stem 40, the communication between the lower end of
the vertical groove 45 and the inside of the large diameter
cylinder portion 22 is shut off by bringing the lower end of the
basic cylinder portion 62 into contact with the flange portion
43.
[0566] The second air suction valve 90 is fitted to the lower half
external surface of the basic cylinder portion 62 of the second
piston 60. The second air suction valve 90 is provided with a short
cylinder fitted to the lower half external surface of the basic
cylinder portion 62 and a thin-wall diaphragm 91 having an
elasticity which is projected annularly to the diagonal upper
outside from the lower end of the short cylinder 92. The end
portion of the diaphragm 91 is formed in a thick-wall portion, and
the upper surface of the thick-wall portion is in contact with the
lower surface of the middle horizontal board shape portion in the
stepped cylinder portion 63 of the second piston 60 with
pressure.
[0567] In the second air suction valve 90 structured in the
above-mentioned way, the elastic deformation of the diaphragm 91
can be easily made, and the second air suction valve 90 can be
opened and closed securely, because the thick-wall portion is
provided on the end portion of the diaphragm 91.
[0568] As shown in FIG. 55, the second air suction valve 90 is
descended in a state that it is closed to pressurize the inside of
the large-diameter cylinder portion 22 when the stem 40 is
descended. If the second air suction valve 90 is provided in the
position opposite to FIG. 55 (namely, in a state that it is
inverted) due to any mistakes, it is impossible to pressurize the
inside of the large-diameter cylinder portion 22 and the
pressurization is irresponsive, and accordingly the trouble which
has occurred in the second air suction valve 90 can be discovered
without delay, because the diaphragm 91 is in contact with the
projecting portion 66 in the stepped cylinder portion 63 of the
second piston 60 so that the valve can not be closed by the second
air suction valve 90.
[0569] The first air suction valve 80 is provided on the
cylinder-shaped rib 152 of the attaching trunk 150. The first air
suction valve 80 comprises a cylinder portion 83 fitted to the
external surface of the cylinder-shaped rib 152 of the attaching
trunk 150, a seal cylinder portion 81 which is extended in a skirt
shape to the diagonal upper outside from the lower part external
surface of the cylinder portion 83 and has an elasticity and a seal
cylinder portion 82 which is extended downward from the lower part
internal surface of the cylinder portion 83.
[0570] A little gap is formed in the space between the cylinder
portion 83 and the peripheral wall internal surface of the
large-diameter cylinder portion 22. The end portion of the seal
cylinder portion 81 is in contact with the upper part internal
surface of the peripheral wall of the large-diameter cylinder
portion 22 with pressure. As shown in FIG. 54, in the seal cylinder
portion 82, the internal surface of the seal cylinder portion 82 is
brought into contact water-tightly with the external surface of the
vertical cylinder portion in the stepped cylinder portion 63 of the
second piston 60 when the stem 40 is at the upper limit.
[0571] There is not any possibilities that the first air suction
valve 80 falls off from the cylinder-shaped rib 152 by the
high-pressure air, even if the air within the container body
high-pressurized by temperature rise and the like passes through
the air hole 27 of the flange portion 21 of the cylinder member 20
to get into the upper part of the large-diameter cylinder portion
22, because the first air suction valve 80 is structured in the
above-mentioned way.
[0572] The liquid suction valve 30 is received within the
small-diameter cylinder portion 24 and the upper part of the liquid
suction valve 30 is inserted into the lower part of the stem
40.
[0573] A plurality of engagement pins 32 are projected to the
portion a little upper from the lower end of the liquid suction
valve 30, and the engagement pins 32 are fitted to the space among
the vertical ribs 26 provided vertically on the lower part internal
surface of the small diameter cylinder portion 24 in a state that
they can be moved upward and downward.
[0574] The lower end of the liquid suction valve 30 functions as a
lower-part valve body 31, and the lower part valve body 31 closes
the liquid suction hole of the small-diameter cylinder portion 24,
when the liquid suction valve 30 is descended.
[0575] The upper end of the liquid suction valve 30 functions as an
upper-part valve body 35 in a state that it is formed in an upward
skirt shape, and the upper-part valve body 35 is held by the
internal surface of the vertical rib 42 provided vertically on the
internal surface of the stem 40 and can be slid on the internal
surface of the vertical rib 42.
[0576] Accordingly, when the stem 40 is descended, the stem 40 and
the liquid suction valve 30 are descended together in the
beginning. After the lower part valve body 31 of the liquid suction
valve 30 comes into contact with the lower end of the
small-diameter cylinder portion 24 to close the liquid suction
valve hole, the liquid suction valve 30 is stopped and the stem 40
continues to be descended.
[0577] On the other hand, when the stem 40 is ascended, although
the liquid suction valve 30 is ascended with the stem 40 in the
beginning, the liquid suction valve 30 is stopped and the stem 40
continues to be ascended after the engagement pin 32 comes into
contact with the lower surface of the coil spring 39.
[0578] Further, the plurality of vertical ribs 42 are provided in a
state that they are dispersed with respect to the circumferential
direction, a right-upward position of the cylinder portion 53 of
the first piston 50 is a starting point and the position in which a
predetermined space is opened downward from the liquid suction
valve 70 is an end point.
[0579] In the state of FIG. 54 in which the pump head 100 is in the
uppermost position, the upper-part valve body 35 is separated from
each of the vertical ribs 42 and is brought into contact
fluid-tightly with the valve seat 52 provided on the upper end
internal surface of the cylinder portion 53 of the first piston 50
to shut off between the upper and lower parts of the stem 40 in the
part. On the other hand, as shown in FIG. 55, in a state that the
pump head 100 is depressed to be held engagedly on the attaching
trunk 150, the upper part valve body 35 of the liquid suction valve
30 gets to the portion upper than the region in which the vertical
ribs 42 are formed within the stem 40 so as to shut off between the
upper and lower parts of the stem 40 fluid-tightly in the part.
[0580] In the container structured in the above-mentioned way, the
bubble whose diameter is suitable for the use can be bubbled easily
by changing the number of the bubbling elements 132 to be provided
and the direction of the bubbling element 132 and so on, because
the net 133 is provided extendedly on the upper end of the short
cylinder 135 to form the bubbling element 132, the fitting portion
(casing 131) for fitting the bubbling element 132 is formed long in
the vertical direction, and the fitting portion is set up in the
length into which a plurality of bubbling elements 132 can be
fitted in a line so as to fit a single or a plurality of bubbling
elements 132 to the cylinder hole portion.
[0581] According to an experiment, the bubbling of the fine and
equalized bubbles could be obtained, when one bubbling element 132
in which a net 133 was provided extendedly on the upper end of the
short cylinder 135 was fitted to the upper part, and one similar
bubbling element 132 was fitted to the lower part in a state that
it was inverted within the casing 131 respectively, as shown in
FIG. 54 and FIG. 55.
[0582] Besides, although it is not illustrated, the bubbles of
medium diameter could be bubbled, when only one bubbling element
132 in which the net 133 was provided on the lower end of the short
cylinder 135 was fitted to the lower part of the casing 131.
[0583] Further, the bubbles of large diameter could be bubbled when
only one bubbling element 132 in which the net 133 was provided
extendedly on the upper end of the short cylinder 135 was fitted to
the upper part of the casing 131.
[0584] Besides, the diameter of the bubbles could be changed
gradually, when the fitting position of only one fitted bubbling
element 132 was moved in order.
[0585] [Modified Example of the Embodiment 10]
[0586] Then, the modified example of the embodiment 10 will be
described in accordance with FIG. 56.
[0587] In the modified example, the pump head 100 is structured
such that a thread cylinder 18a is extended downward from the
flange-outside margin which is provided projectingly from the
peripheral upper part of the fitting cylinder 108, a fitting
cylinder 108e is provided upward from the flange outside margin in
a state that it is stood up and a top board 108f is fitted to the
upper end portion of the fitting cylinder 108e.
[0588] Besides, in the stem 40, a vertically hanging wall 55 is
provided downward from the upper end portion of the vertical rib 42
in a state that a predetermined width is opened so that the upper
part valve body 35 is fitted fluid-tightly to the space between the
internal surface of the vertical rib 42 and the vertically hanging
wall 55 to shut off between the upper and lower parts of the stem
40 fluid-tightly in this portion, when the pump head 100 is
depressed to be stopped engagedly on the attaching trunk 150. The
other structures are the same as the cases shown in FIG. 54 and
FIG. 55.

[0615] The stepped cylinder portion 63 is formed in a step shape in
which the side of the basic cylinder portion 62 is high and the
side of the seal cylinder portion 61 is low.
[0616] A plurality of air holes 64 are provided on the part
adjacent to the basic cylinder portion 62. The upper end of the
basic cylinder portion 62 functions as a thin-wall elastic portion
which is enlarged to a little upper outside, and the end of the
basic cylinder portion 62 is brought into contact air-tightly with
the lower part internal surface of the inside cylinder portion 102
with pressure.
[0617] A plurality of projections 66 are provided on the internal
surface of the vertical cylinder part in the stepped cylinder
portion 63. In the stepped cylinder portion 63, the stood-up
engaging cylinder 67 is provided from the upper horizontal
plate-shape portion in a state that a little gap is opened in the
space between the basic cylinder portion 62 and the engaging
cylinder 67, and the air hole 64 is provided on the horizontal
plate-shape portion positioned in the above-mentioned gap.
[0618] The second piston 60 is provided on the stem 40 in a state
that it can be moved upward and downward a little stroke in which
the position where the lower end of the basic cylinder portion 62
is fitted to the internal surface in the rising wall 44 of the
flange portion 43 of the stem 40 as shown in FIG. 57 is a lower
limit, and the position where the lower end of the inside cylinder
portion 102 which constitutes the outside wall of the concave
portion 102d is fitted air-tightly to the space between the basic
cylinder portion 62 of the second piston 60 and the engaging
cylinder 67 to close the air hole 64 is an upper limit.
[0619] In the range in which the second piston 60 is moved upward
and downward a little stroke, a plurality of vertical grooves 45
are provided on the external surface of the stem 40 of the part in
which the basic cylinder portion 62 of the second piston 60 is
slid, and-the communication between the lower end of the vertical
groove 45 and the inside of the large-diameter cylinder portion 22
is shut off by bringing the lower end of the basic cylinder portion
62 into contact with the flange portion 43, when the second piston
60 is descended to the lower limit for the stem 40.
[0620] The second air suction valve 90 is fitted to the lower half
external surface of the basic cylinder portion 62 of the
above-mentioned second piston 60. The second air suction valve 90
is provided with a short cylinder 92 fitted to the lower half
external surface of the basic cylinder portion 62 and a thin-wall
diaphragm 91 having elasticity which is projected annularly to the

The end portion of the diaphragm 91 is formed to the thick-wall
portion, and the upper surface of the thick-wall portion of the
diaphragm 91 is in contact with the lower surface of the middle
horizontal plate shape portion in the stepped cylinder portion 63
of the second piston 60 with pressure.
[0621] In the second air suction valve 90 structured in the
above-mentioned way, the elastic deformation of the diaphragm can
be made easily, and the second air suction valve 90 can be opened
and closed securely, because the thick-wall portion is provided on
the end portion of the diaphragm 91.
[0622] The second air suction valve 90 is descended in a state that
it is closed to pressurize the inside of the large-diameter
cylinder portion 22 when the stem 40 is descended. If the second
air suction valve 90 is provided in the position opposite to the
drawing (namely, in a state that it is inverted) due to any
mistakes, it is impossible to pressurize the inside of the large
diameter cylinder portion 22 and the pressurization is
irresponsive, and accordingly the trouble which has occurred in the
second air suction valve 90 can be discovered without delay,
because the diaphragm 91 is in contact with the projecting portion
63 in the stepped cylinder portion 66 of the second piston 60 so
that the valve can not be closed by the second air suction valve
90.
[0623] The first air suction valve 80 is provided on the
cylinder-shaped rib 152 of the attaching trunk 150. The first air
suction valve 80 comprises a cylinder portion 83 fitted to the

portion 83.
[0624] A little gap is formed in the space between the cylinder
portion 83 and the internal surface of the peripheral wall of the
large-diameter cylinder portion 22. The end portion of the seal
cylinder portion 81 is in contact with the upper part internal
surface of the peripheral wall of the large-diameter cylinder
portion 22 with pressures As shown in FIG. 57, in the seal cylinder
portion 82, the internal surface of the seal cylinder portion 82 is
brought into contact water-tightly with the external surface of the
vertical cylinder portion in the stepped cylinder portion 63 of the
second piston 60 when the stem 40 is at the upper limit.
[0625] The liquid suction valve 30 is received within the small
diameter cylinder portion 24 so as to insert the upper part of the
liquid suction valve 30 into the lower part of the stem 40.
[0626] The lower end of the liquid suction valve 30 functions as a
lower part valve body 31, and the lower part valve body 31 closes a
liquid suction valve hole of the small diameter cylinder portion
24, when the liquid suction valve 30 is descended. In the liquid
suction valve 30, a plurality of engagement pins 32 are projected
in the portion a little upper than the lower part valve body 31,
and the engagement pins 32 are fitted to the space among the
vertical ribs 26 provided vertically on the lower part internal
surface of the small-diameter cylinder portion 24 in a state that
they can be moved upward and downward.
[0627] The upper end portion of the liquid suction valve 30
functions as an upper-part valve body 35 and is formed such that
the diameter is widened in an upward skirt shape. The upper-part
valve body 35 is held by the internal surface of the vertical ribs
42 provided vertically on the internal surface of the stem 40 and
can be slid to the internal surface of the vertical ribs 42.
[0628] Accordingly, when the stem 40 is descended, the stem 40 and
the liquid suction valve 30 are descended together in the beginning
and the lower part valve body 31 of the liquid suction valve 30
comes into contact with the lower end of the small diameter
cylinder portion 24 to close the liquid suction valve hole. After
that, the liquid suction valve 30 is stopped and the stem 40
continues to be descended.
[0629] On the other hand, when the stem 40 is ascended, the liquid
suction valve 30 is also ascended with the stem 40 in the beginning
and the engagement pin 32 comes into contact with the lower end of
the coil spring 39. After that, the liquid suction valve 30 is
stopped and the stem 40 continues to be ascended.
[0630] Further, the plurality of vertical ribs 42 are provided in a
state that they are dispersed with respect to the circumferential
direction and that the just-upper position of the cylinder portion
53 of the first piston 50 is a starting point and the lower
position of the liquid discharge valve 70 is an end point. In the
state of FIG. 57 that the pump head is in the uppermost position,
the upper-part valve body 35 is separated from each of the vertical
ribs 42 to be in contact with the valve seat 52 provided on the
upper end inside of the cylinder portion 53 of the first piston 50
so as to shut off between the upper and lower parts of the stem 40
fluid-tightly in the part.
[0631] A mouthpiece 500 for injection is provided on the end of the
nozzle 107 of the pump head 100.
[0632] As shown in FIG. 58, the mouthpiece 500 comprises a fitting
cylinder 503 fitted to and fixed on the end inside of the nozzle
107, an annular flange portion 504 which is projected to the
outside from the end external surface of the fitting cylinder 503
to be in contact with the front end surface of the nozzle 107, a
conical cylinder shaped wall 501 which is extended to the front
from the end of the fitting cylinder 503, and a nozzle 502 is
opened in the point portion of the conical cylinder shaped wall
501.
[0633] In the container with a pump for discharging bubbles, the
seal of the lower end of the basic cylinder portion 62 of the
second piston 60 is opened by depressing the pump head 100, and the
pressurized air within the large-diameter cylinder portion 22
passes through the air passage 102c to be introduced into the
vapor-liquid mixing chamber 46.
[0634] At the same time, the liquid suction valve 30 is descended,
the lower end opening of the small-diameter cylinder portion 24 is
closed by the lower-part valve body 31 and the liquid within the
small diameter cylinder portion 24 pushes up the liquid discharge
valve 70 to be introduced into the vapor-liquid mixing chamber 46
so that the liquid and the air are mixed in the vapor-liquid mixing
chamber 46.
[0635] Then, the liquid is bubbled when the mixture of the air and
liquid passes through the net 133 of the bubbling element 132, and
the bubbled liquid is accelerated by the mouthpiece provided on the
end of the nozzle 107 to be discharged in a linear shape from the
nozzle 502.
[0636] In the pump for discharging bubbles 10, the bubble whose
diameter is suitable for the use can be bubbled easily by changing
the number of the bubbling elements 132 to be provided and the
direction of the bubbling element 132 and so on, because the net
133 is provided extendedly on the upper end of the short cylinder
135 to form the bubbling element 132, the cylinder hole portion
(casing 131) for fitting the bubbling element 132 is formed long in
the vertical direction, and the cylinder hole portion is set up in
the length into which a plurality of bubbling elements 132 can be
fitted in a line so as to fit a single or a plurality of bubbling
elements 132 to the cylinder hole portion.
[0637] According to an experiment, like the embodiment 11 shown in
FIG. 57, the bubbling of the fine and equalized bubbles could be
obtained, when one bubbling element 132 in which a net 133 was
provided extendedly on the upper end of the short cylinder 135 was
fitted to the upper part, and one similar bubbling element 132 was
fitted to the lower part in a state that it was inverted within the
casing 131. Although the illustration is omitted, the bubbles of
medium diameter could be bubbled, when only one bubbling element
132 in which the net 133 was provided on the lower end of the short
cylinder 83 was fitted to the lower part of the casing 131.
Further, the bubbles of large-diameter could be bubbled when only
one bubbling element 132 in which the net 133 was provided
extendedly on the upper end of the short cylinder 83 was fitted to
the upper part of the casing 131.
[0638] Besides, the diameter of the bubbles could be changed
gradually, when the fitting position of only one fitted bubbling
element 132 was moved in order.
[0639] In the pump for discharging bubbles 10, the discharged
bubbles can be accelerated in the conical cylinder shaped wall 501
to be discharged off at a relatively long distance in a linear
shape, because the mouthpiece 500 for injection is provided on the
end of the nozzle 107. Accordingly, the diversified use for the
container with a pump for discharging bubbles of late years is
matched up, and the demand can be met sufficiently.
[0640] Besides, the structure of the mouthpiece is very simple, so
the productive efficiency of the mouthpiece is excellent and it can
be manufactured at a low price. Further, the mouthpiece can be
provided and fixed on the conventional pump for discharging bubbles
10 of this kind.
[0641] The following experiment was performed in reference to the
opening diameter L of the nozzle 502.
[0642] The discharging state of the bubbles was measured by using
the container with a pump for discharging bubbles of the
above-mentioned structure and changing the opening diameter L of
the nozzle 502. In the measurement, the discharging state when the
bubbles were discharged upon the target body separated at 15 cm
from the nozzle 502 was observed visually and the pressure sense at
the moment was examined. The result is shown in the following Table
1. Further, the pressure sense of the pump head 100 is referred to
as "head pressure" in Table 1.

Further, the codes .largecircle., .DELTA. and X in the item of
"discharging state" indicate the following criteria. .largecircle.
Discharged in a linear shape smoothly. .DELTA. Discharged liquid

.largecircle., .DELTA. and X in the item of "head pressure"
indicate the following criteria. .largecircle. Can be pressured
lightly. .DELTA. Pressured a little heavily. X Pressured rather
heavily.
[0643] Accordingly, it is preferable that the opening diameter of
the nozzle 502 is less than 2.0 mm, because the bubbles can be
injected linearly at the distance of at least 15 cm when the
opening diameter of the nozzle 502 is less than 2.0 mm. On the
other hand, it is preferable that the opening of the nozzle 502 is
within the range of 1.0 mm-2.0 mm, because the pump head 100 is
pressured heavily when the opening is too small.
[0644] [Embodiment 12]
[0645] The container with a pump for discharging bubbles of the
embodiment 12 will be described in accordance with FIG. 59 and FIG.

[0652] A rising cylinder portion 156 is provided from the central
part of the top wall 154 in a state that it is stood up. The
central portion of the rising cylinder portion is opened, and a
central cylinder portion 151 in which an outside air suction groove
which is extended to the vertical direction is provided on the

the rising cylinder portion 156.
[0653] A cylinder-shaped rib 152 is extended downward from the back
of the top wall 154, a short cylinder is extended downward from the
peripheral portion of the top wall 154, and the short cylinder is
inserted into the annular groove 21a of the large-diameter cylinder

provided on the stem 40 in a state that it is projected from the
lower end of the stem 40. The seal portion 51 is capable of sliding
on the internal surface of the small diameter cylinder portion 24
fluid-tightly. The second piston 60 is provided on the stem 40 in a
state that it can be moved upward and downward only a little
stroke.
[0656] A flange portion 43 in which an annular groove is provided
on the inside portion is provided on the central portion of the
stem 40 in a state that it is projected to the outside, and a
metallic coil spring 39a for energizing the stem 40 and the pump
head 100 upward is made to lie in the space between the annular
groove of the flange portion 43 and the concave groove 23a of the
large-diameter cylinder 22.
[0657] A cylinder-shaped valve seat which is stood up through the
inward flange is provided on the upper part internal surface of the
stem 40, and a spherical liquid discharge valve 70 which can be
brought into contact with and separated from the cylinder-shaped
valve seat is received in the upper part inside of the stem 40. The
liquid discharge valve 70 is made up of the materials other than
metals such as synthetic resin and ceramics.
[0658] In the pump head 100, an outside cylinder portion 101 and an
inside cylinder portion 102 are extended downward in the inside and
outside dual cylinder shape from the peripheral portion of the top
board portion 103, a nozzle 107 in which the basic end is opened to
the upper end internal surface of the inside cylinder portion 102
is extended horizontally, and the end of the nozzle 107 is made to
pass through the outside cylinder portion 101 to be projected to
the outside.
[0659] The lower part of the pump head 100 is inserted into the
central cylinder portion 151 of the attaching trunk 150 in a state
that it can be slid. The lower part of the inside cylinder portion
102 is formed to the large-inside-diameter portion, and the upper
part of the stem 40 is fitted to the inside lower half of the
large-inside-diameter portion.
[0660] In the internal surface of the large-inside-diameter
portion, a plurality of vertical grooves 102a are formed on the
part to which the stem 40 is fitted. The upper end of the vertical
groove 102a is positioned in a portion upper than the upper end
surface of the stem 40. Further, although the pump head 100 is
dual-cylinder-structured in the embodiment 12, a single cylinder
structured pump head 100 can be substituted for it.
[0661] The second piston 60 comprises a basic cylinder portion 62
fitted to the upper part external surface of the stem 40 in a state
that it can be slid, a seal cylinder portion 61 fitted to the
internal surface of the large-diameter cylinder portion 22 in a
state that it can be slid, and a stepped cylinder portion 63 for
connecting the basic cylinder portion 62 to the seal cylinder
portion 61. The stepped cylinder portion 63 is formed in a step
shape in which the side of the basic cylinder 62 is high and the
side of the seal cylinder portion 61 is low. The upper end portion
of the basic cylinder portion 62 functions as a thin-wall elastic
portion and is brought into contact air-tightly with the lower part
internal surface of the inside cylinder portion 102 with
pressure.
[0662] A stood-up engaging cylinder 67 is provided from the upper
horizontal plate shape portion in the stepped cylinder portion 63
in a state that a little gap is opened in the space between the
basic cylinder portion 62 and the engaging cylinder 67, and a
plurality of air holes 64 are provided on the horizontal plate
shape portion positioned in the gap.
[0663] The second piston 60 is provided on the stem 40 in a state
that it can be moved upward and downward only a little stroke in
which the position where the lower end of the basic cylinder
portion 62 is fitted to the annular groove of the upper surface of
the flange portion 43 of the stem 40 as shown in FIG. 59 is a lower
limit, and the position where the lower end of the inside cylinder
portion 102 is fitted air-tightly to the space between the basic
cylinder portion 62 of the second piston 60 and the engaging
cylinder 67 to close the air hole 64 like FIG. 60 is an upper
limit.
[0664] In the range in which the second piston 60 can be moved
upward and downward only a little stroke, a plurality of vertical
grooves 45 are provided on the external surface of the stem 40 of
the part in which the basic cylinder portion 62 of the second
piston 60 is slid, and as shown in FIG. 59, when the second piston
60 is descended to the lower limit for the stem, the communication
between the lower end of the vertical groove 45 and the inside of
the large diameter cylinder portion 22 is shut off by bringing the
lower end of the basic cylinder portion 62 in contact with the
flange portion 43 air-tightly.
[0665] The bubbling unit 130 has a casing 131 in which the upper
part is fitted to the inside upper part of the inside cylinder
portion 102 and the lower-part is formed to a small-diameter
portion and is fitted to the upper part inside of the stem, and the
short cylinders 135 and 135 in which a net 133 is provided
extendedly on the upper end are fitted to the inside of the casing
131 in a state that they are in piles upward and downward.
[0666] A groove 131d is provided on the external surface of the
small diameter portion of the casing 131, and an air passage 160
for making the inside of the large-diameter cylinder portion 22 of
the lower part of the second piston 60 and a vapor-liquid mixing
chamber 46 mentioned later communicate with one another is made up
of the groove 131d, vertical groove 102a and a vertical groove
45.
[0667] The small-diameter portion of the casing 131 inserted into
the upper end portion of the stem 40 has an inward flange on the
lower end and a blocking piece 131c is extended downward from the
inward flange. The blocking piece 131c prevents the liquid
discharge valve 70 from closing the hole of the inward flange, when
the liquid discharge valve 70 is pushed up by the liquid flowing
into the casing 131 from the inside of the stem 40.
[0668] The space between the inward flange and the liquid discharge
valve 70 functions as a vapor-liquid mixing chamber 46, and the
liquid which has passed through the liquid discharge valve 70 and
the high-pressure air which has passed through the air passage to
be flown thereto are mixed in the vapor-liquid mixing chamber
46.
[0669] Further, the casing 131 is not always required and the
bubbling element 132 can be fitted to the upper part inside of the
inside cylinder portion 102 directly.
[0670] The second air suction valve 90 is fitted to the lower half
external surface of the basic cylinder portion 62 of the second
piston 60. The second air suction valve 90 is provided with a short
cylinder 92 fitted to the lower half external surface of the basic
cylinder portion 62 and a thin-wall diaphragm 91 having an
elasticity which is projected in an annular shape to the diagonal
upper outside from the lower end of the short cylinder 92. The end
portion of the diaphragm 91 is in contact with the lower surface of
the middle horizontal plate shape portion in the stepped cylinder
portion 63 of the second piston 60 with pressure.
[0671] The first air suction valve 80 is provided on the
cylinder-shaped rib 152 of the attaching trunk 150. The first air
suction valve 80 comprises a cylinder portion 83 fitted to the
external surface of the cylinder-shaped rib 152 of the attaching
trunk 150 and a seal cylinder portion 81 which is extended in a
reverse-skirt shape to the diagonal upper outside from the lower
part external surface of the cylinder portion 83 and has an
elasticity. The end portion of the seal cylinder portion 81 is in
contact with the upper part internal surface of the peripheral wall
of the large-diameter cylinder portion 22 with pressure.
[0672] When the inside of the container body 1 is pressurized
negatively by decreasing the liquid, the elastic deformation of the
seal cylinder portion 81 of the first air suction valve 80 to the
inside occurs so that the seal cylinder portion 81 approaches the
cylinder portion 83. As a result, the outside air flown into the
attaching trunk 150 from the space between the central cylinder
portion 151 of the attaching trunk 150 and the pump head 100 passes
through the space between the upper end surface of the
large-diameter cylinder portion 22 and the lower surface of the top
wall 154 of the attaching trunk 150, and through the annular groove
21a and the air hole 27 to flow into the container body 1 so as to
dissolve the negative pressure state.
[0673] The liquid suction valve 30 is received within the
small-diameter cylinder portion 24. The liquid suction valve 30 is
suspended in a state that the upper part of the liquid suction
valve 30 is inserted into the stem 40, and a plurality of
engagement pins 32 which are projected from the lower part external
surface are positioned in a portion lower than the engaging
cylinder 29 fixed on the lower part inside of the small diameter
cylinder portion 24 so that they can be held engagedly on the lower
end of the suspending cylinder 29.
[0674] The lower end of the liquid suction valve 30 functions as a
lower part valve body 31, and the lower-part valve body 31 is in
contact with the valve seat 24a provided on the bottom of the
small-diameter cylinder portion 24 to close the suction hole 24b
when the liquid suction valve 30 is descended.
[0675] The upper end portion of the liquid suction valve 30
functions as an upper-part valve body 35, and the upper-part valve
body 35 is held by the upper part internal surface of the cylinder
portion 53 and can be slid to the internal surface of the stem
40.
[0676] Accordingly, when the stem 40 is descended, the stem 40 and
the liquid suction valve 30 are descended together in the beginning
and the lower part valve body 31 closes the suction hole 24b of the
small diameter cylinder portion 24. After that, the liquid suction
valve 30 is stopped and the stem 40 continues to be descended.
[0677] On the other hand, when the stem 40 is ascended, the liquid
suction valve 30 is also ascended with the stem 40 in the beginning
and the engagement pin 32 comes into contact with the lower end of
the engaging cylinder 29 to be engaged. After that, the liquid
suction valve 30 is stopped and the stem continues to be
ascended.
[0678] A cover 202 is fitted to the peripheral surface of the
rising cylinder portion 156 of the attaching trunk 150 in a state
that it can be removed.
[0679] Further, each of the members to which the materials are not
restricted is formed by synthetic resin materials according to
circumstances.
[0680] In the container with a pump for discharging bubbles, the
large and small gaps are formed on the space between the valve seat
24a of the small diameter cylinder portion 24 and the lower part
valve body 31 of the liquid suction valve 30 and the space between
the upper surface of the internal surface of the stepped cylinder
portion 63 of the second piston 60 and the lower end surface of the
outside cylinder portion 101 of the pump head 100 respectively in
the state shown in FIG. 59.
[0681] Hereupon, the size of the gap in the space between the upper
surface of the internal surface of the stepped cylinder portion 63
and the lower end surface of the outside cylinder portion 101 is
smaller than the gap in the space between the valve seat 24a and
the lower part valve body 31. The liquid flows into the
vapor-liquid mixing chamber 46 after the pressurized air flows into
the vapor-liquid mixing chamber 46 in the beginning, because the
size of the gaps is set up in the above-mentioned large and small
relation.
[0682] To be more specific, when the pump head is depressed in the
state shown in FIG. 59, the pump head 100 and the stem 40 and the
liquid suction valve 30 are descended against the second piston 60
and the cylinder member 20, and the lower end of the basic cylinder
portion 62 of the second piston 60 is separated from the upper
surface of the flange portion 43 of the stem 40 to open the air
passage 160 extending to the vapor-liquid mixing chamber 46 from
the large diameter cylinder portion 22.
[0683] Then, the lower end of the outside cylinder portion 101
comes into contact with the upper surface of the stepped cylinder
portion 63 of the second piston 60, and the second piston 60 is
descended with the stem 40 to the cylinder member 20, and
accordingly the air within the large-diameter cylinder portion 22
is pressurized, the high pressure air passes through the air
passage 160 and starts flowing into the vapor-liquid mixing chamber
46.
[0684] After that, the lower part valve body 31 of the liquid
suction valve 30 comes into contact with the valve seat 24a of the
small-diameter cylinder portion 24 to close the suction hole 24b.
Then, the stem 40 in which the first piston 50 is provided on the
lower end is descended to the liquid suction valve 30, and
accordingly the liquid within the small-diameter cylinder portion
24 and the stem 40 is pressurized to open the liquid discharge
valve 70 and the liquid starts flowing into the vapor-liquid mixing
chamber.
[0685] Accordingly, the liquid flows into the vapor-liquid mixing
chamber 46 after the pressurized air flows into the vapor-liquid
mixing chamber 46 in the beginning.
[0686] As a result, the mixing ratio of the air volume and liquid
volume can be kept proper even in the early stage of depressing the
pump head 100, and the bubbling is never incomplete due to the lack
of the air volume for the liquid volume as in the prior art.
[0687] After that, the liquid which has been mixed with the air in
the vapor-liquid mixing chamber 46 is bubbled when it passes
through the net 133 of the bubbling unit 130 to be discharged in a
foamy state from the nozzle 107.
[0688] Besides, the coil spring 39a never touches the liquid to
become rusted, because the coil spring 39a which energizes the stem
40 upward is received within the large-diameter cylinder portion 22
which functions as a cylinder for air. Accordingly, the received
liquid is never discolored nor degenerated by the rust adhered to
the external surface of the coil spring as in the prior art.
[0689] [Embodiment 13]
[0690] The container with a pump for discharging bubbles of the
embodiment 13 will be described in accordance with FIG. 61 and FIG.
62.
[0691] The container with a pump for discharging bubbles comprises

the container body 1, and the upper part of the cylinder member 20
functions as a large-diameter cylinder portion 22 and the lower
half which is hung down through a bottom plate portion 23 from the

[0697] In the first air suction valve 80, an elastic plate which is
opened to upper outside is projected from the lower end of a
fitting cylinder to the central cylinder portion 151, the elastic
plate upper end external surface is in contact with the upper end
cylinder part internal surface of the cylinder member 20 with
pressure and when the inside of the container body 1 is pressurized
negatively due to the decrease in the liquid, the elastic plate

[0698] The stem 40 is projected from the small diameter cylinder
portion 24 in a state that it is energized upward by the coil
spring 39 whose lower end is mounted on the plurality of vertical
ribs 26 and is received within the small diameter cylinder portion
24. The first piston 50 is fitted to the lower end of the stem 40,
and the internal surface of the fitting cylinder 108 hung down from

[0699] The liquid discharge valve 70 is provided on the upper part
internal surface of the stem 40, and a bubbling element 132 in
which both upper and lower ends of a short cylinder 135 are closed
with a net 133 is fitted to the upper part internal surface of the
fitting cylinder 108 of the upper part of the liquid discharge
valve 70.
[0700] A fitting plate 71 is formed such that it is attached
fittingly to the upper end part internal surface of the stem 40 so
that an elastic piece 72 will brings a valve body 73 into contact
with a valve seat 41 with pressure by the valve seat 41 of taper
shape of lower part small diameter provided on the upper part
internal surface of the stem 40 and the liquid discharge valve 70
in which the valve body 73 of lower part small diameter is provided
on the lower end of the plurality of elastic pieces 72 hung down
from the lower surface of the fitting plate 71 provided with a
hole. A plurality of vertical ribs 42 are provided vertically on
the internal surface of the stem 40 in the lower part of the valve
seat 41.
[0701] The fitting cylinder 108 hung down from the pump head 100 is
formed in a dual cylinder shape so as to prevent the fitting
cylinder 108 from becoming wall-thicken. The lower end portion of
the fitting cylinder 108 to which the upper part of the stem 40 is
fitted functions as a large inside diameter portion 108. Besides, a
vertical groove 108a is provided on the internal surface of the
fitted cylinder 108 in the space between the upper end of the large
inside diameter portion 108g and the fitting part of the short
cylinder 135, and the external surface of the short cylinder 135 is
provided with the vertical groove 135 which makes a vapor-liquid
mixing chamber 46 formed on the space between the fitting plate 71
of valve member 41 and the short cylinder 135 and the vertical
groove 108a communicate with one another so that both upper ends of
vertical grooves 108a and 135a are connected with one another to
function as a part of an air-passage 160 mentioned later.
[0702] A flange portion 43 which projects a cylinder portion to the
diagonal upper outside from the outside end of a plate portion
which is projected to the outside is provided on the middle portion
external surface of the stem 40 so that the flange portion 43 can
be engaged to the second piston 60 fitted into the large-diameter
cylinder portion 22.
[0703] The second piston 60 is formed such that a stepped cylinder
portion 63 which is projected from a basic cylinder portion 62
fitted to the external surface of the stem 40 in the upper part of
the flange portion 43 is connected to the seal cylinder portion 61
fitted to the large diameter cylinder portion 22, and a passage is
provided on the space between the external surface of the stem 40
to which the basic cylinder portion 62 is fitted and the basic
cylinder portion 62 by installing a groove 62a on the internal
surface vertically and so on, and the upper end of the basic
cylinder portion 62 is enlarged to the upper outside to fit the
upper end periphery to the internal wall surface of the
large-inside-diameter portion 108g air-tightly.
[0704] An air hole 64 is provided on the stepped cylinder portion
63, and an elastic cylinder is fitted air-tightly to the external
surface of the basic cylinder portion 62 in the lower part of the
stepped cylinder portion 63 to close the air hole 64 an elastic
thin plate 93 which is projected to the outside from the elastic
cylinder, and the second air suction valve 90 to the inside of the
large-diameter cylinder portion 22 is formed by the air hole 64 and
the elastic thin plate 93.
[0705] However, the second air suction valve 90 may be needless, if
the above-mentioned air hole 64 is provided so as to close the
lower end surface of the fitting cylinder 108 when the pump head
100 is depressed.
[0706] The second piston 60 can be moved upward and downward only a
little stroke to the stem 40, and when the stem-40 is descended to
the second piston 60 by depressing the pump head 100, the flange
portion 43 is separated from the lower end of the basic cylinder
portion 62 to open the air passage 160 which is formed by the
groove 62a, vertical groove 108a and the like are formed so as to
make the inside of the large-diameter cylinder portion 22 and the
vapor-liquid mixing chamber 46 communicate with one another. The
lower end surface of the fitting cylinder 108 comes into contact
with the upper surface of the stepped cylinder portion 63 to push
down the second piston 60.
[0707] After the stem 40 is descended, when the pump head 100 is
released, the flange 43 comes into contact with the lower end
surface of the basic cylinder portion 62 to close the air passage,
and the second piston 60 and the stem 40 are pushed up together so
that the outside air passes through the space between the central
cylinder portion 151 and the fitting cylinder 108 and the air hole
64 to get into the large diameter cylinder portion 22.
[0708] A liquid suction valve 30 whose lower end functions as a
lower-part valve body 31 is projected from the inside of the bottom
of the small cylinder portion 24 in a state that the upper part is
fitted into the stem 40 so as to be moved upward and downward a
little stroke freely by the frictional engagement with the stem
40.
[0709] In the liquid suction valve 30, a plurality of engagement
pins 32 are projected radially from the lower part external
surface, and as shown in FIG. 62, the engagement pins 32 are fitted
to the vertical ribs 26 in the bottom of the small-diameter
cylinder portion 24 in a state that they can be moved upward and
downward so that the upper limit of the liquid suction valve 30 is
determined by enlarging the liquid suction valve 30 to the lower
end of the coil spring 39 mounted on the upper end of the vertical
rib 26, and the lower limit is determined by bringing the lower
part valve body 31 into contact with the valve seat 24a to close
the valve when the stem 40 is descended.
[0710] A vertical groove 33a is provided on the liquid suction
valve 30 and an upper-part valve body 35 which is extended to the
diagonal upper outside is provided on the upper end portion of the
liquid suction valve 30 so as to engage the upper end external
surface of the upper-part valve body 35 to the internal surface of
the stem 40 by frictional force.
[0711] Further, although the cylinder portion 53 stood up from the
seal portion 51 is fitted into the lower part of the stem 40 in the
embodiment 13, the stem 40 and the first piston 50 may be formed in
a body.
[0712] In the state shown in FIG. 61, the large and small gaps are
formed on the space between the valve seat 24a formed on the bottom
internal surface of the small diameter cylinder portion 24 and the
lower part valve body 31 of the lower end of the liquid suction
valve 30 which is stood up from the inside of the bottom and whose
upper part is fitted into the stem 40, and the space between the
stepped cylinder portion 63 of the second piston 60 fitted into the
large-diameter cylinder portion 22 and the lower end of the fitting
cylinder 108 hung down from the pump head 100 respectively.
[0713] If the pump head 100 is depressed in the state, the pump
head 100, the stem 40 and the liquid suction valve 20 are descended
to the second piston 60 and the cylinder member 20, and the second
piston 60 is also descended to the cylinder member 20 by contacting
the lower end of the fitting cylinder 108 with the stepped cylinder
63, and then the lower part valve body 31 is descended to the valve
seat 24a to close the valve.
[0714] The air passage 160 is opened by descending the pump head
100 and the like and the air within the large-diameter cylinder
portion 22 is pressurized by descending the second piston 60 to get
into the vapor-liquid mixing chamber 46. After that, the liquid
within the small diameter cylinder portion-24 and the stem 40 are
pressurized to open the liquid discharge valve 70, the liquid gets
into the mixed air to be mixed with the air and the liquid passes
through the bubbling element 132 to be discharged in a foamy state
from the nozzle 107, when the valve which is formed by the valve
seat 24a and the lower part valve body 31 is closed and the first
piston 50 and the stem 40 are descended to the liquid suction valve
30.
[0715] If the pump head 100 is released after being depressed, the
liquid suction valve 30 and the stem 40 are ascended to the
cylinder member 20 and the second piston 60, the flange portion 43
of the stem 40 comes into contact with the lower end surface of the
basic cylinder portion 62 to push up the second piston 60, and the
liquid suction valve 30 is stopped to the cylinder member 20 and
the stem 40 is moved to the upper limit by bringing the engagement
pin 32 which is projected radially from the lower part external
surface of the liquid suction valve 30 into contact with the lower
end surface of the coil spring 39.
[0716] The mixing ratio of the air volume and liquid volume can be
kept proper even in the beginning of depressing the pump head 100,
and the bubbling is never incomplete due to the lack of the air
volume for the liquid volume as in the prior art, because, first of
all, when the pump head is depressed, the valve seat 24a of the
small diameter cylinder portion 24 is closed by the lower part
valve body 31 of the liquid suction valve 30 after the air passage
160 for making the large diameter cylinder portion 22 communicate
with the vapor-liquid mixing chamber 46 is opened and the
pressurized air starts flowing into the vapor-liquid mixing chamber
46, and accordingly the inside of the small diameter cylinder
portion 24 between the liquid suction valve 30 and the liquid
discharge valve 70 and the inside of the stem 40 are pressurized to
open the liquid discharge valve 70 and the liquid gets into the
vapor-liquid mixing chamber 46 after the pressurized air starts
flowing into the vapor-liquid mixing chamber 46 in the
above-mentioned way. This is due to the fact that the gap between
the stepped cylinder portion 63 of the second piston 60 and the
fitting cylinder 108 hung down from the pump head 100 is smaller
than the gap between the valve seat 24a of the small-diameter
cylinder portion 24 and the lower part valve body 31 of the liquid
suction valve 30.
[0717] The air within the large-diameter cylinder portion 22 does
not leak through the air hole 64, and accordingly the air within
the large-diameter cylinder portion 22 can be delivered securely to
the vapor-liquid mixing chamber 46 through the air passage 160 when
the pump head 100 is depressed, because the elastic cylinder of the
first air suction valve 80 is fitted air-tightly to part of the
external surface of the basic cylinder portion 62 in the lower part
of the stepped cylinder portion 63 of the second piston 60, and the
air hole 64 provided on the stepped cylinder portion 63 is closed
by the elastic thin plate 93 which is projected to the outside from
the elastic cylinder to function as the second air suction valve 90
to the inside of the large-diameter cylinder portion 22.
[0718] The inside of the stem 40 in the lower part of the liquid
discharge valve 70, the inside of the small diameter cylinder
portion 24 and the like are filled with the liquid all the time,
because the liquid discharge valve 70 is closed elastically by
energization, and accordingly the liquid within the stem 40 and the
like flow into the vapor-liquid mixing chamber 46 simultaneously
with the release of the liquid discharge valve 70 by the depressing
of the pump head 100. As a result, the bubbles in which the air and
liquid are mixed at the proper ratio can be discharged
simultaneously with the depressing of the pump head 100.

the engagement cylinder 155 hung down from the top wall 154 so that
the whole pump for discharging bubbles 10 is formed in a state that
it can be removed in a body by removing the attaching trunk 150
from the neck portion 2 of the container body 1.
[0722] The upper end portion of the large diameter cylinder portion
22 is projected a little to the upper part of the flange portion
21. Accordingly, the fitting cylinder of the first air suction
valve 80 is extended to the lower part of the central cylinder
portion 151, the elastic plate is projected to the upper outside
through the flange from the lower end of the fitting cylinder, and
the upper end of the elastic plate is in contact with the upper end
portion of the internal surface of the large-diameter cylinder
portion 22 with pressure.
[0723] The upper end of the cylinder portion 53 stood up from the
seal portion 51 of the firs piston 50 to be fitted into the lower
part of the stem 40 is curved to the upper inside, and the upper
end surface of the cylinder portion 53 is brought into contact
water-tightly with the middle portion external surface of the upper
part valve body 35 with pressure in a state that the elastic
deformation can occur. The upper-part valve body 35 is provided
such that the middle portion within the stem 40 is closed when the
stem is ascended so that there is no trouble even if the liquid
discharge valve 70 is opened when the container falls down and so
on.
[0724] The liquid discharge valve 70 is formed in a ball valve, and
the casing 131 is fitted to the space between the bubbling element
132 in the upper part of the liquid discharge valve 70 and the
liquid discharge valve 70. The upper part of the casing 131
functions as a large diameter portion 131a, the lower half of the
bubbling element 132 and fitted into the large-diameter portion
131a, the lower part of the casing 131 is formed to a
small-diameter portion 131 and fitted into the upper end portion of
the stem 40 and a plurality of blocking pieces 131a are hung down
from the lower end surface of the small diameter portion 131b so
that the liquid discharge valve 70 does not close the lower end
opening of the casing 131 by the pushing up of the liquid passing
through the discharge valve hole.
[0725] The air passage 160 is formed by the vertical groove 108a of
the internal surface of the fitting cylinder 108 to which the upper
part of the stem 40 is fitted, a horizontal groove 131e provided on
the lower end surface of the large diameter portion 131a and a
groove 131f provided vertically on the external surface of the
