Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to the lid of the vacuum
bottles for closing the opening part on the top of the liquid
containers and more specifically it relates to the lid which does
not have to be removed every time the liquid is poured.
[0003] 2. Prior Art
[0004] The lid is used to close the part for pouring the liquid,
which is the opening part of the liquid container and in most of
the cases, it is so constructed as to be attached to the liquid
container by screw-encasing.
[0005] However, the screw-encasing involves rotating the whole part
of the lid every time the liquid is poured, wherein the lid is
rotated to be removed and attached, thus making the pouring action
troublesome. This is how the structure as disclosed in the patent
publication No. Hei9-299254 is thought out. In other words, in the
center of the lid there is formed a pouring inlet piercing through
from the top to the bottom. According to this construction, the
liquid can be poured by simply opening up the upper lid attached on
the upper part of the lid, which upper lid can be opened and closed
and thus, the pouring action can be convenient as the lid does not
have to be taken off. It is noted that according to the
above-mentioned invention, there is no structure for actively
closing the pouring outlet for pouring the liquid. So long as it is
used normally, there might be no need to be provided with the means
for closing the pouring outlet, but in case the liquid container
should fall down, the liquid might be spilt out after passing
through the pouring outlet.
SUMMARY OF THE INVENTION
[0006] The main purpose of the present invention is to prevent the
liquid from spilling out while it is easy to pour the liquid into
the vacuum bottle and to get rid of any inconvenience.
[0007] This is also to provide a lid of the liquid container with a
pouring outlet for pouring the liquid into the liquid container to
which it is to be attached, while the pouring inlet is piercing
through vertically and in the below side of the whole part of the
said lid there is formed a pouring outlet for pouring the liquid by
inclining the liquid container, together with the closing material
for closing the said pouring outlet in a manner allowing it to be
opened and closed, wherein there is provided a resilient means to
push toward the closing direction in respect of the said closing
material and to provide a lid of the liquid container provided with
the operating material for opening the said pouring outlet, while
shifting the position of the closing material against the resilient
force of the said resilient means.
[0008] When the liquid is poured into the liquid container provided
with the above said lid, the pouring inlet is used while the lid is
on. When pouring the liquid inside, there is no need to take off
the lid, and thus it takes only an easy and simple task to pour the
liquid inside. When the liquid is thus poured, the liquid inside
will not spill over through the pouring outlet even if the liquid
container is inclined. This is because the pouring outlet is
actively closed by the closing material provided with the resilient
force of the resilient means and even when the liquid container
falls down, it is possible to prevent the liquid from spilling over
from the pouring outlet.
[0009] When the liquid is poured out, the closing material may be
shifted in respect of its position by operating the operating
material to open the pouring outlet. The operating material may be
composed of an appropriate means like a pushing button and
levers.
[0010] Furthermore, on the top of the said pouring outlet there may
be formed a concave part in the form of a funnel so that the liquid
can be poured easily without spilling over.
[0011] Additionally, on the top of the pouring outlet there may be
provided a lid capable of opening and closing by a simple action
other than a screw-encasing and when the pouring outlet is closed
by the said lid, the liquid may be prevented from spilling out of
the pouring outlet when the liquid container falls down, without
having trashes get into the liquid container or changing the
temperature of the liquid. For instance, on the top of the lid
there is attached a lid part for opening and closing and a
retaining part for keeping closed the said lid for opening and
closing, wherein below the above said lid part for opening and
closing there may be formed a closing protrusion for closing the
upper part of the pouring outlet.
[0012] Furthermore, the said operating material may have the
encasing part on one end and on the other end there may be formed a
lever for pushing down, provided with the pushing down device. The
lever-principle may be applied and it takes only light force and
easy operation.
[0013] In this case, the pushing part may be placed on the upper
side of the handle formed onto the liquid container. By using the
fingers holding the handle and the thumb, the pushing-down lever
can be lowered, thus easily pouring the liquid with one hand
only.

be bolted by the bolt 15 from inside on the outer surface of the
body material 8. On the other hand, in front of the shoulder
material 11 there is formed a pouring part 16 in the shape of a
beak.
[0025] In mounting the vacuum bottle 4, the body material 8 and the
shoulder material 11 are formed together as described above and
they will contain the inner container 6 from under through the seal
material 17 in the form of a ring and the said bottom material 9
may be attached to the below part of the body material 8 while the
adjuster material 10 is attached to the bottom material 9, thus
maintaining firmly the inner container 6.
[0026] The lid 1 is a flat round form encased in the said opening
part 7 at the below part, which has an exposed part (upper part)
bigger than the below part so that the above shoulder material 11
is along with the said lid. The lid 1 is formed with the upper
material 18 and the below material 19 formed under the said upper
material 18 and the pushing-down lever 20 encased inside the said
upper material 18 and the closing material 21, which can be lowered
by the said pushing-down lever 20, together with the pouring inlet
2 and the pouring outlet 3 as described above. In other words, on
the upper side of the upper material 18 exposed above the shoulder
material 11 there is formed a concave part 22 in the form of a
funnel and there is formed the part 23 of the pouring outlet 23 in
the shape of a tube, vertically formed from the center bottom of
the concave part 22 to provide the said pouring outlet 2. To attach
the lid to the opening part 7, the male screw 24 formed on the
outer surface of the below material 19 is to be screwed against the
female screw 25 formed on the shoulder material 11.
[0027] In the above rear region of the said upper material 18,
there is formed a supporting device 26 for supporting the opening
and closing lid material 27 for opening and closing the said
concave part 22 and in the above forward region of the said upper
material 18 there is provided a retaining nail 28 for retaining the
forward end part of the said opening and closing lid material 27 so
that it can be retained and released, thus providing keeping the
closed condition. Above the opening and closing lid material 27
there is extended a half-circle plate from back to forward,
providing a grip 29 for operation. Also, below the opening and
closing lid material 27 there is provided a closing protrusion 30
in the shape of a half-globe made of appropriate materials like
silicone rubber so that the upper end of the said pouring inlet 2
can be closed when the said closing protrusion 30 is closed,
wherein the pouring inlet 2 extending from the bottom of the
concave part 22 can be sealed off.
[0028] In the forward part inside the upper material 18 there are
formed two ribs 31 separated in a determined distance and between
these ribs 31 there is maintained an encased axis 32 formed on one
end of the said pushing-down lever 20 is designed to open the
pouring outlet 3 by pushing down the said closing material 21 and
the other end is extended backward protruding outside the upper
material 18, wherein above the handle 14 of the shoulder part 11
there is protruded a pushing-down part 33. On the other hand, in
the intermediate part along the said pouring inlet part 23 there is
a hole perforated and in its inside edge there is a pushing-down
edge 34.
[0029] The above pouring outlet 3 is formed on the said below
material 19. In the pouring inlet 2 in the center part of the below
part 19 there is formed a supporting material for maintaining the
closing material 21 and on the outer location of the said
supporting material there is formed a double-wall structure formed
of the outer wall 35 placed outside and the inner wall 36 which is
low and positioned far inside of the outer wall 35. From the bottom
of the said double-wall part there are extended the outer wall 35
and the inner wall 36 upwardly in the form of a reversed L letter,
wherein below the lid 1 (regarding the below material 19) there is
a pouring outlet 37 on the front position on the said part.
[0030] The above closing material 21 is provided with the
cylinder-shaped part 38 suitably thick for being encased in the
pouring inlet part 23 of the upper material 18 wherein they can
almost scrape, together with the disk part 39 in the shape of a
donut below the said cylinder-shaped part 38, extending outwardly.
The outer region of the said disk part 39 is in touch with the
outer wall 35 of the said double-wall from under so that the below
part of the pouring outlet 3 can be closed.
[0031] On the upper part of the closing material 21 there is
provided the pushed-down part 40 to be pushed down by the pushing
down edge 34 of the said pushing-down lever 20 and just below it
there is formed a blade-guard-like step 41.
[0032] This step 41 is provided with the ring device 42 in the
shape of a washer, putting spring force to push the closing
material 21 upwardly toward the closing direction by means of the
compressing coil spring 44 provided between the ring-shaped step 43
formed on the inner part of the inner wall 36 of the below material
19 and the above said step 42. The numbers 45 and 46 in the figure
indicate the seal material.
[0033] In order to pour the liquid into the vacuum bottle as
constructed above, it is necessary only to open the opening and
closing lid 27 maintained by the retaining nail 28 as shown in the
FIG. 4. When the opening and closing lid 27 is opened, the pouring
inlet 2 will be opened, wherein the liquid may be poured through
the said pouring inlet 2. Above the pouring inlet 2 there is formed
a concave part 22 in the shape of a bowl so that it is possible to
pour the liquid without having to spilling over as when using a
funnel. When opening and closing the opening and closing lid 27,
the opening and closing lid 27 has only to be brought up or lowered
for an easy operation so that the lid does not have to be rotated
to be removed every time the liquid is poured, thus providing for
an easy and rapid pouring.
[0034] When pouring out the liquid, the pushing-down part 33 of the
pushing-down lever 20 may be lowered by the thumb of the hand
holding the handle 11 as shown in the FIG. 1 with the virtual line
and also shown in the FIG. 5 so that the pouring outlet 3 will be
opened and inclined. It only provides an easy and simple or rapid
pouring action.
[0035] Furthermore, when the opening and closing lid 27 is closed
upon pouring the liquid, the closing protrusion 30 in the form of a
half-globe is closing the upper end of the pouring inlet 2.
Therefore, thermal effects can be improved and trashes can be
prevented from getting in.
[0036] As for the pouring inlet 2, its below end is closed by the
closing material 21, sealing off the inside part from outside and
even when the vacuum bottle 4 should fall down, the liquid inside
can be prevented from spilling over.
[0037] The vacuum bottle 4 corresponds the liquid container of the
present invention, wherein the compressing coil spring 44
corresponds to the resilient means, the opening and closing lid 27
corresponding to the opening and closing lid, the retaining nail 28
corresponding to the retaining part and the encased axis 32
corresponding to the encased part. However, the present invention
is not to be construed as being limited to the above
construction.
[0038] For instance, the opening and closing lid 27 may be formed
on the upper material 18 through the hinge. On the other hand, the
operating material may be formed with the pushing button like the
one using the cams besides the pushing-down lever 20.
[0039] Furthermore, the lid of the present invention may be adopted
for the liquid container like a pot not having a thermal
function.
