Description
TECHNICAL FIELD
[0001] This invention relates to a liquid mixing container capable
of mixing two or more kinds of liquids together when in use.
BACKGROUND ART
[0002] Some dental adhesives are contained in a container for use
repetitively a plurality of times while other dental adhesives are
contained in a container for use for only one time of treatment.
The former container for use repetitively a plurality of times
contains the adhesive in an amount enough for the treatment of a
number of times; i.e., at the time of use, a lid member is opened,
and the adhesive is taken out by only a required amount for the
treatment. The latter container contains the adhesive in an amount
for only one time of treatment; i.e., the container in a closed
state is opened, and is discarded after the use irrespective of the
amount of the adhesive that is remaining.
[0003] Dental materials of the type of mixing two liquids have
often been used; i.e., two liquid that are separately contained are
mixed together just before the use, and are used. The two-liquid
mixing container has been frequently used since it obviates the
need of injecting the two liquids while measuring them or the need
of separately providing the mixing container.
[0004] For example, a patent document 1 discloses a two-liquid
mixing container wherein a sheet-like separating member is provided
for separating a liquid chamber on the front end side of an
injector-shaped cylinder from a liquid chamber of the rear end
side, different liquids are contained in the liquid chambers, and a
piston is pushed into the cylinder to mix the two liquids together
breaking the separating member.
[0005] Further, a patent document 2 discloses a two-liquid mixing
container wherein a slide member is provided to slide in the
container, two liquid chambers are arranged on the slide member in
the direction of diameter of the container, and upper ports of the
liquid chambers are sealed with sheet-like separating members. The
container is provided with unsealing members facing the two upper
openings to pierce the separating members simultaneously, and the
slide member is moved toward the unsealing members to unseal the
liquid chambers by the unsealing members thereby to mix the
treating solutions in the two liquid chambers together.

OUTLINE OF THE INVENTION
Problems that the Invention is to Solve
[0008] So far, as disclosed in the patent documents 1 and 2, any
portion of the two-liquid mixing container is pushed so that the
liquids are mixed together. According to the patent document 1, in
particular, in case the container is fallen by mistake, the piston
is pushed due to a shock and the liquids may be mixed together. It
may, further, happen that the piston is accidentally pushed in
against the will. According to the two-liquid mixing container of
the patent document 2 in which the slide member is contained in the
container body, the slide member can be prevented from being pushed
in by erroneous operation, but a jig is necessary for pushing in
the slide member at the time of mixing the two liquids
together.
[0009] According to the two-liquid mixing containers of the patent
documents 1 and 2, further, the liquids are separately packed by
using a thin sheet, and at the time of use, the sheets are pierced
through to mix the liquids together. If the sheets are pierced
through, however, the fragments of sheets may be mixed into the
mixed liquid becoming a cause of contaminants.
[0010] The present invention was accomplished under the above
circumstances, and provides a liquid mixing container which
prevents two liquids (or three or more liquids) from being mixed
together by erroneous operation and does not permit sheet-like
contaminants from mixing into the mixed liquid.
Means for Solving the Problems
[0011] To achieve the above object, the present invention provides
a liquid mixing container comprising:
[0012] a container body having a plurality of liquid chambers
provided with liquid injection openings, and a mixing chamber for
communicating with each of the liquid chambers through the liquid
injection openings; and
[0013] a liquid chamber opening/closing member fitted in the mixing
chamber of the container body is capable of switching the liquid
chambers and the mixing chamber into a communicated state or a
closed state;
[0014] wherein the liquid chamber opening/closing member is
provided with sealing members which, at an advanced position of
having entered into the liquid injection openings, work to close
the injection openings to separately close the liquid chambers and,
at a backward position, work to open the injection openings
permitting the liquid chambers to be communicated with the mixing
chamber.
[0015] The sealing members of the liquid chamber opening/closing
member of the liquid mixing container are desirably convex portions
capable of being inserted in the liquid injection openings.
[0016] The liquid chamber opening/closing member of the liquid
mixing container at the backward position can be turned in the
circumferential direction with respect to the container body.
[0017] The container body of the liquid mixing container may have a
liquid take-out opening formed With the liquid chamber on the side
opposite to the position where the liquid injection opening is
provided, and may be provided with a lid member for closing the
liquid take-out opening.
[0018] The liquid mixing container may be such that the liquid
chamber opening/closing member is provided with shaft-like first
support portions for supporting the container body, the lid member
is provided with shaft-like second support portions for supporting
the container body and, after the lid member is detached from the
container body, the first support portions and the second support
portions are assembled together in a cross shape to support the
container body in an erected attitude with the liquid take-out
opening of the container body facing upward.
Effects of the Invention
[0019] The mixing container of the present invention is capable of
storing liquids having different components by separately packing
them in the each liquid chambers. Upon pulling the liquid chamber
opening/closing member, the liquids that had been separately packed
are mixed together in the mixing chamber in the container
exhibiting the following effects in addition to the basic effects
of the two-liquid mixing container.
[0020] The container body is provided with liquid injection
openings for feeding the to-be-mixed liquids to the liquid
chambers, and the liquid opening/closing member is provided with
the sealing members which are fitted in the mixing chamber on the
other end side of the container body. The sealing members, at the
advanced position of having entered in the liquid injection
openings, work to close the injection openings to separately close
the liquid chambers and, at a backward position, work to open the
injection openings permitting the liquid chambers to be
communicated with each other. Upon pulling the liquid chamber
opening/closing member instead of pushing it in, the liquid
chambers are permitted to be communicated with the mixing chamber.
Therefore, the liquids are prevented from being erroneously mixed
together that could result from receiving shocks or strong
gripping.
[0021] The sealing members of the liquid chamber opening/closing
member are convex portions that can be inserted in the liquid
injection openings and, at the reversed position, can be turned in
the circumferential direction with respect to the container body.
Therefore, upon turning the liquid chamber opening/closing member
after having been pulled, valve bodies (closing portions) of the
liquid chamber opening/closing member play the role of a stirrer
enabling the mixed liquid to be stirred and mixed together.
[0022] Because of its structure, the liquids have not been
separately packed by using a thin sheet. At the time of use,
therefore, the liquids are mixed together without piercing through
the sheet, and it does not happen that the fragments of sheet are
mixed into the container.

MODE FOR CARRYING OUT THE INVENTION
[0030] The container according to an embodiment of the invention
will now be described with reference to the drawings.
[0031] FIG. 1 is a disassembled view of a two-liquid mixing
container that contains adhesives for dental treatment, FIG. 2 is a
sectional view of when the liquid chambers of the two-liquid mixing
container are closed, and FIG. 3 is a sectional view of when the
liquid chambers are communicated with the mixing chamber.
[0032] The two-liquid mixing container 1 is a container of the
so-called type that is discarded after the use of one time, and
comprises a plastic container body 2, a lid member 3 provided at an
upper portion of the container body 2, and a liquid chamber
opening/closing member 4 disposed at a lower portion of the
container body 2.
[0033] A circular cylindrical portion 5 is provided at the lower
portion of the container body 2. The cylindrical portion 5 includes
a mixing chamber 20 therein, has its lower end opened, and has a
liquid chamber-forming portion 6 at an upper portion thereof. The
interior of the liquid chamber-forming portion 6, in this
embodiment, includes two liquid chambers, i.e., a first liquid
chamber 7 and a second liquid chamber 8. The liquid chambers 7 and
8 have a circular shape in transverse cross section, and extend in
the up-and-down direction of the container body 2. The liquid
chambers 7 and 8 are forming liquid injection openings 7a and 8a
(see FIG. 4) on the lower end side facing the mixing chamber 20
(upper end side of the liquid chambers in FIG. 4). The one or first
liquid chamber 7 is longer than the other or second liquid chamber
in the up-and-down direction of the container body 2, reaching the
upper lid member 3, and its liquid take-out opening 7b is closed by
the lid member 3 (see FIGS. 6 and 7). The upper portion of the
second liquid chamber 8 is separated by the ceiling wall of the
liquid chamber-forming portion 6.
[0034] An annular protuberance 12 is formed on the outer
circumference at the lower portion of the container body 2 so as to
protrude toward the outer circumferential side of the container
body 2.
[0035] The lid member 3 is formed integrally with the container
body 2, and includes a lid body 10 and a wing portion 14. The lid
body 10, as described above, closes the interior of the first
liquid chamber 7. The wing portion 14 is so formed as to protrude
toward the right and left outer sides of the lid body 10. The wing
portion 14 is coupled to the lid body 10 (at one end), and is
provided with support legs 15 coupled to the other end (outer most
end) of the wing portion 14. The wing portion 14 is a plate member
of a square shape, and the upper and lower ends of the support legs
15 are protruding toward both the upper and lower sides beyond the
upper portion and the lower portion of the wing portion 14. The
portion coupling the container body 2 to the lid member 3 is
forming a brittle portion 13 by, for example, decreasing the
thickness to be smaller than other portions or forming a notch.
Upon turning the lid member 3, the brittle portion 13 permits the
lid member 3 to be easily separated away from the container body
2.
[0036] The liquid chamber opening/closing member 4 can be fitted to
the container body 2 from the openings at the lower end of the
mixing chamber 20, and is provided with a base portion 17 of a
cylindrical shape. The base portion 17 is provided with sealing
members 18 and 19 that protrude upward from the upper surface
thereof. The sealing members 18 and 19 are forming sealing members
18a and 19a at their intermediate portions in the up-and-down
direction. The sealing members 18a and 19a may be formed in a
manner that the circumferential surfaces of the sealing members 18
and 19 are annularly protruded outwards integrally therewith, or
may be formed by fitting separate members such as O-rings to the
circumferential surfaces thereof, or may not be formed if the
liquids have large viscosities.
[0037] The base portion 17 has an outer diameter nearly equal to
the caliber of the mixing chamber 20 of the container body 2 so as
to maintain such a relationship that the outer circumferential
surface of the base portion 17 is in close contact with the inner
circumferential surface of the mixing chamber 20. When the
adhesives having small viscosities are to be contained, the base
portion may provide sealing relying on such means as annular
sealing members 18a, 19a or the O-rings in the same manner as the
sealing members 18 and 19.
[0038] The liquid chamber opening/closing member 4 is so formed and
fitted as can be slid on the circumferential wall surface of the
mixing chamber 20 in both the up-and-down direction and the
circumferential direction. The sealing members 18 and 19, too, are
formed in a size that fits to the liquid injection openings 7a and
8a of the liquid chambers 7 and 8 in close contact thereto so as to
maintain air-tightness of the liquid chambers 7 and 8.
[0039] The liquid opening/closing member 4 can slide between an
advanced position where it is positioned deeply inside the mixing
chamber 20 relative to the container body 2 (see FIG. 2) and a
reversed position where it is shallowly fitted in the mixing
chamber 20 (see FIG. 3). When the liquid chamber opening/closing
member 4 is at the advanced position as shown in FIG. 2, the
sealing members 18 and 19 are fitted into the liquid injection
openings 7a and 8a to close the liquid chambers 7 and 8 and to
air-tightly separate the liquid chambers 7 and 8. At its reversed
position as shown in FIG. 3, the liquid chamber opening/closing
member 4 opens the liquid chambers 7 and 8. At the reversed
position, an open space is formed in the upper part of the mixing
chamber 20 that had been closed by the base portion 17, and the
liquid chambers 7 and 8 are allowed to communicate with each other
through the open space in the mixing chamber 20.
[0040] Wing portions 22 are formed at the lower portion of the base
portion 17 of the liquid chamber opening/closing member 4 facing
each other in the direction of diameter of the base portion 17 and
protruding outward. The wing portions 22 are coupled at the ends on
one side to the base portion 17, and have support legs 23 coupled
to the other ends (distal ends) of the wing portions 22. The wing
portions 22 are plate-like members of a square shape, and the upper
and lower ends of the support legs 23 protrude upward and downward
beyond the upper portion and the lower portion of the wing portions
22.
[0041] A pair of rod-shaped engaging portions (hook members) 24 are
formed extending upward on the upper surfaces of the wing portions
22 at the intermediate portions thereof in the direction in which
they extend. Pawls 24a (see FIGS. 1 and 4) are formed at the distal
ends of the engaging portions 24 protruding inward in the direction
of diameter. Inclined surfaces 24b facing inward and downward (see
FIG. 4) are formed at the ends of the pawls 24a. When the liquid
chamber opening/closing member 4 is at its reversed position, the
pawls 24 hook to the annular protuberance 12 of the container body
2 to restrict the reversed position of the liquid chamber
opening/closing member 4. The advanced position of the liquid
chamber opening/closing member 4 may be restricted by the
engagement of the liquid injection openings 7a, 8a and the sealing
members 18, 19, or by the upper end surface of the base portion 17
and by the lower end wall surface of the liquid chambers 7 and
8.
[0042] A slit 26 is formed between the right and left wing portions
22, 22. The slit 26 has a width equal to the thickness of the wing
portion 14. A positional relationship between the wing portion 14
and the wing portions 22 is such that the wing portion 14 and the
wing portions 22 are arranged in the same direction, i.e., arranged
on the same plane in a state where the liquid injection openings 7a
and 8a are closed by the sealing members 18 and 19.
[0043] The two-liquid mixing container 1 is such that the container
body 2, at first, has not been combined with the liquid chamber
opening/closing member 4 but the lid member 3 is coupled to the
container body 2 integrally together. To introduce the adhesives
into the container body 2, the container body 2 is turned upside
down as shown in FIG. 4. By using an injection jig 28a, an adhesive
A is introduced into the first liquid chamber 7 through the liquid
injection opening 7a of the first liquid chamber 7. Next, by using
an injection jig 28b, an adhesive B is introduced into the second
liquid chamber 8 through the liquid injection opening 8a of the
second liquid chamber 8 so will not to be mixed into the first
liquid chamber 7. Here, it will be effective if the adhesives A and
B that are used have such properties as to commence the chemical
reaction right after they are mixed together to undergo
solidification.
[0044] After the adhesives A and B are injected by predetermined
amounts, the mixing chamber 20 of the container body 2 is combined
with the liquid chamber opening/closing member 4. At this moment,
the annular protuberance 12 of the container body 2 interferes with
the pawls 24a. However, the pawls 24a are forming inclined surfaces
24b at their upper portions and do not become an obstacle. To place
the liquid injection openings 7a, 8a and the sealing members 18, 19
in position, the wing portion 14 of the lid member 3 and the wing
portions 22 of the liquid chamber opening/closing member 4 are set
to be in the same direction (rotational angle); i.e., the sealing
members 18, 19 are inserted in the liquid injection openings 7a,
8a, and the liquid chambers 7 and 8 are closed as shown in FIG. 2.
Thus, the adhesives A and B are separately injected into the liquid
chambers 7 and 8, and are not solidified.
[0045] A dentist who is going to treat teeth by using the adhesive
contained in the container may now grip the container body 2 by his
one hand and may pull the liquid chamber opening/closing member 4
downward of the container body 2 by his other hand. Therefore, the
state shown in FIG. 2 is shifted to the state shown in FIG. 3. The
pawls 24a of the engaging portions 24 hook to the annular
protuberance 12, and the liquid chamber opening/closing member 4
does not escape from the container body 2. This liberates the
sealing state of the sealing members 18, 19 and the liquid
injection openings 7a, 8a and, besides, an open space is formed in
the mixing chamber 20 on the upper surface of the liquid chamber
opening/closing member 4 permitting the first liquid chamber 7 and
the second liquid chamber 8 to be communicated with each other.
[0046] Here, the liquid chambers 7 and 8 are communicated with the
mixing chamber 20 not by pushing the liquid chamber opening/closing
member 4 but by pulling it. Therefore, the liquids are prevented
from being mixed together by erroneous operation that could be
caused by shocks given to the two-liquid mixing container 1 or by
strongly gripping it in the course of handing the two-liquid mixing
container 1 up to mixing the adhesives together.
[0047] Because of its structure, further, the liquid chambers 7 and
8 are communicated through without piercing a thin sheet, and no
fragment of sheet contaminates into the container.
[0048] Thus, the adhesive A in the first liquid chamber 7 and the
adhesive B in the second liquid chamber 8 are mixed together. Since
the sealing members 18 and 19 have now been disengaged from the
liquid injection openings 7a and 8a, it is allowed to turn the
liquid chamber opening/closing member 4 relative to the container
body 2 in the circumferential direction (around the axis thereof).
The sealing members 18 and 19 provided on the upper surface of the
liquid chamber opening/closing member 4 serve as stirrer members
for favorably mixing the two kinds of adhesives together.
[0049] Referring to FIG. 5, to unseal the liquid chambers of the
two-liquid mixing container 1, the lid member 3 is faced upward. By
gripping the container body 2 or the wing portions 22 by one hand
and gripping the wing portion 14 of the lid member 3 by the other
hand, the container body 2 and the wing portion 14 are turned in
the directions opposite to each other to cut the brittle portion
13. Upon cutting the brittle portion 13, an adhesive take-out
opening 7b is formed in the container body 2. Here, the wing
portion 14 has a long distance L between the support legs 15 and 15
at both ends thereof to produce a large moment of force and,
therefore, the brittle portion 13 can be cut with a small
force.
[0050] After the lid member 3 is separated away from the container
body 2, the wing portion 14 is so turned that its direction is
shifted in the circumferential direction by 90 degrees relative to
the wing portions 22 of the container body 2. Thereafter, the lid
member 3 is brought to just under the liquid chamber
opening/closing member 4 and is inserted in the slit 26 formed in
the lower portion of the liquid chamber opening/closing member 4.
Namely, the two-liquid mixing container 1 is coupled in the shape
of a rocket, and the lower portion of the two-liquid mixing
container 1 is formed in a cross shape by the wing portions 22 and
the wing portion 14 (FIG. 7).
[0051] The two-liquid mixing container 1 will be placed at a
suitable position in a state where the liquid take-out opening 7b
of the container body 2 is facing upward; i.e., the container 1
maintains a stably erected attitude. In combining the container
body 2 with the lid member 3, the slit 26 serves as a target
position enabling the wing portions 14 and 22 to be easily put
together in a cross shape.
[0052] The dentist takes out the adhesive by inserting an end of a
rod 30 in the take-out opening 7b of the container body that is
placed maintaining stability. The container is prevented from
inclining or falling over while the adhesive is being taken
out.
[0053] Thus, the dentist lets the container body 2 erected on a
suitable place, and is allowed to apply the adhesive onto the
patient's teeth using both hands. After the treatment, the
two-liquid mixing container 1 is discarded. Here, since the
container body 2 and the lid member 3 have been coupled integrally
together, they do not separate away after discarded. Usually, the
lid member 3 becomes rubbish (unnecessary article) at a moment when
the lid member 3 is separated away from the container body 2.
According to the invention, however, the lid member 3 can be
effectively utilized before it turns into rubbish.
[0054] When the wing portions 22 and the wing portion 14 are
assembled together in the cross shape, the two-liquid mixing
container 1 becomes bulky in both the longitudinal and transverse
directions. In a state where the two-liquid mixing container 1 has
not been used (FIG. 2), however, the wing portion 14 and the wing
portions 22 are nearly in a planar positional relationship. In the
state where the wing portions 14 and 22 are laid down, the
cylindrical portion 5 of the liquid chamber opening/closing member
4 assumes the greatest thickness as compared to the thicknesses of
the wing portions 14 and 22. When some of many two-liquid mixing
containers 1 that are not in use are to be packaged in a box, the
thickness of the whole package of the containers 1 can be
decreased. By overlapping the two-liquid mixing containers 1 in,
for example, a laid-down attitude, an increased number of
two-liquid mixing containers 1 can be contained in a decreased
packaging volume.
[0055] Though an embodiment of the present invention was described
above, it should be noted that the invention can be, further,
modified or varied in a variety of ways without departing from the
technical spirit and scope of the invention, as a matter of
course.
[0056] For example, though the above embodiment has dealt with a
dental container for containing dental adhesives, the container is
not limited to the dental use only but can be applied to any other
containers that require stably erected attitude.
[0057] In the above embodiment, further, the container body 2 and
the lid member 3 are coupled together through the brittle portion
13 that is so formed as can be broken down. The lid member 3,
however, may be of the threaded type or the insertion (fit)
type.
[0058] The engaging portions 24 formed in a pair on the upper
surfaces of the wing portions 22 at intermediate portions thereof
in a direction in which they extend, may, further, be formed in a
number of three or more in the circumferential direction of the
cylindrical portion 5 of the container body 2 maintaining a
predetermined distance to more firmly restrict the reversed
position of the liquid chamber opening/closing member 4, or may,
further, be formed in a manner of surrounding the cylindrical
portion 5.
[0059] Though the liquid chambers 7 and 8 in this embodiment were
provided in a number of two, they may be provided in a number of
three or more to realize a container for using the adhesive by
mixing three of more liquids together.
[0060] In the above embodiment, further, the brittle portion 13 was
formed on the first liquid chamber 7 and was broken to form the
liquid take-out opening 7b. Instead of forming the liquid take-out
opening 7b, however, the liquid chamber opening/closing member 4
may be removed from the container body 2, and the mixed liquid may
be taken out from the side of the mixing chamber 20 (liquid
injection openings 7a, 8a). In this case, in the invention, the
liquid take-out opening becomes the same as the liquid injection
openings. In this case, further, the engaging portions 24 may be
omitted.
