Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a pump-filled liquid container such as an air pot, and particularly relates to an improvement in the mounting position of an air pump.

[Conventional technology]

In air pots, air pumps have conventionally been used to pressurize the inside of the inner container. This pump is normally incorporated into the lid of the air pot, but it may also be incorporated into the shoulder of the pot in order to reduce the height of the entire pot (see, for example, Japanese Utility Model Publication No. 45638/1983).

When incorporated into the shoulder body of the pot, the air pump has a C-shape that surrounds the outer periphery of the rear half of the plug body, the operation part of the air pump is provided at the rear of the plug body, and the inlet for the liquid in the inner container is Provided in front of the stopper.

[The problem that the idea attempts to solve]

The type that incorporates the air pump into the shoulder body of the pot has the advantage that the total height of the pot can be lower than the type that incorporates the air pump into the lid. However, when the air pump is operated to discharge the liquid from the inner container, the liquid spout and the operation part of the air pump are too far apart in the front-rear direction, so it cannot be said that the usability is good.
Furthermore, since the air pump in this case is of a C-shape that surrounds the rear half of the plug, the shoulder of the pot becomes large and there is a problem in that the compactness of the pot as a whole is impaired.

Therefore, the object of this invention is to solve these problems and provide an air pot that is excellent in terms of usability.

[Means to solve the problem]

In order to solve the above-mentioned problem, this invention blows pressurized air into the inner container 4 of the liquid container main body A from the air pump 1, and the inner container 4 is filled with the pressurized air.
In a pump-filling type liquid container capable of pouring out the liquid inside to the outside through a liquid pouring passage 22 that communicates the inside and outside of the inner container 4, the liquid container main body A
The spout 2 is provided directly below the air pump 1 or in the vicinity of the air pump 1.

[Function] When the air pump 1 is operated, the air pressure inside the inner container 4 increases, and the liquid flows through the liquid pouring passage 22.
It is poured out from the spout 2 below the air pump 1.

〔Example〕

The air pot of the embodiment shown in the attached drawings has a bellows type air pump 1 attached to the upper front surface of the pot as a whole, as shown in FIGS. 1 and 2, and a spout 2 provided directly below it. By pushing the push plate 3 placed over the air pump 1 downward, the inside of the inner container 4 is pressurized and liquid is poured out from the spout 2.

The liquid container main body A houses an inner container 4 made of a vacuum-insulated double bottle in an exterior body consisting of an outer shell 8, a shoulder member 7 attached to the upper part of the outer shell 8, and a bottom member 9 attached to the lower part of the outer shell 8. This is what I did. The tip 5 on the bottom surface of the inner container 4 is of a so-called side tip type, and consideration is given to reducing the height of the pot in this aspect as well.

A shoulder member 7 placed on the upper opening 15 of the inner container 4 via a packing 6 has its lower end engaged with the upper edge of the outer shell 8, and a bottom member 9 screwed onto the lower edge of the outer shell 8.
A tightening body 10 is screwed into the central part of the inner container 4, and the bottom surface of the inner container 4 is tightened by this tightening body 10.
and the liquid container main body A are integrated.

The shoulder member 7 includes an outer peripheral wall 11 formed to have approximately the same diameter as the outer body 8, an upper surface portion 13 formed on approximately the same surface as the plug 12, and an inner peripheral wall 1 into which the head of the plug 12 fits.
4 and a cylindrical liquid supply port 16 that rests on the upper opening 15 of the inner container 4, and a pump cover 43 to be described later.
are combined and integrated.

The liquid supply port 16 is connected to the gasket 12' of the stopper 12.

As shown in FIG. 3, the above-mentioned shoulder member 7 has a recess 17 formed in its front portion with an open outer circumferential wall 11 and an upper surface 13. This recess 17
are both side walls 18, inner wall 19, top wall 20 and bottom wall 2.
1, and the inner wall 19 is formed at a position recessed inwardly from the inner circumferential wall 14 of the shoulder member 7. Therefore, a portion of the plug body 12 is also recessed in accordance with the recessed shape of the inner wall 19. Furthermore, an air hole 23, a pouring hole 24, and an air vent hole 25 are formed in the inner wall 19. A liquid pumping pipe 26 is connected to the inner end of the pouring hole 24 .

The inner peripheral wall 14 of the shoulder member 7 is attached to the outer peripheral edge of the upper wall 20.
A circumferential wall 27 continuous with the arc of the open end is formed in an arc shape, and is adapted to receive the outer circumference of the upper end of the plug body 12.

The bottom wall 21 has three claw plates 2 of the pump lower plate 28.
Insertion holes 29', 30' for inserting 9, 30, 31,
31', one of which is provided with a fixing part 36, and the pump lower plate 28 is fixed to the fixing part 36 with screws 37 (see FIG. 2). Above each insertion hole 29', 30', 31', there is a safety valve device 3.
Eight support ribs 32, 33, and 34 are formed. Further, a pair of opposing claws 39 protruding forward from the outer body 8 is formed at the front end of the bottom wall 21, and a pump cover bottom plate 44 is formed on the lower surface of the pump lower plate 28.
is attached with screws 51 (see Figure 2).
A spout 2 is provided on the pump cover bottom plate 44.

A safety valve device 38 is installed inside the recess 17 described above. The safety valve device 38 prevents hot water from leaking when the pot falls over, and also prevents a child or the like from directly putting their mouth on the spout 2 and inhaling the hot water.

The safety valve device 38 includes the air hole 23 of the shoulder member 7,
It is connected to the spout hole 24 and the air vent hole 25, and further connected to the air hole 41 of the pump lower plate 28 by an air tube 40, and the spout tube 42
is connected to the spout 2 of the pump cover bottom plate 44.

The liquid pumping pipe 26, the passage within the safety valve device 38 connected to the pouring hole 24, and the safety valve device 38
The spout tube 42 connected to the spout tube 42 and the spout 2 connected to the spout tube 42 constitute the liquid spout passage 22 as a whole.

After assembling the pump lower plate 28, pump cover bottom plate 44, and safety valve device 38 as described above, the pump cover 43 is attached to the front surface of these, and the shoulder member 7 is assembled.
The recess 17 is covered.

As shown in FIG.
It has a curved cover surface 47 that is surrounded by a curved side 46 along the curved surface and covers the entire range from the upper surface portion 13 of the shoulder member 7 along the outer peripheral wall 11,
The cylindrical portion 4 protrudes forward on the curved cover surface 47.
A space 49 is formed inside the space 8, and a guide rib 50 is provided on the inner peripheral surface of the space 49.

The above-mentioned pump cover 43 is engaged with the peripheral wall 27 at its arcuate side 45, and is engaged with the pump cover bottom plate 44 at the lower end of the cylindrical portion 48.

The air pump 1 has a space 4 in the cylindrical portion 48 described above.
9 is inserted. The lower end of the air pump 1 is welded and fixed on the pump lower plate 28, and the push plate 3 of the air pump 1 slides on the guide rib 50.

The pump cover 43 also has an end portion of an air tube 40 connected to the air hole 41 of the pump lower plate 28 and a spout tube 42 connected to the spout 2 between the pump lower plate 28 and the pump cover bottom plate 44. Also cover each end.

The air pot of the embodiment has the above configuration, and as shown in FIG. 2, the center line l of the air pump 1 is located somewhat forward of the outer body 8, and the amount of forward protrusion of the air pump 1 is as follows. When a downward pressing force is applied on this median line, the pot is set within a range in which the pot does not fall over due to a shift in the center of gravity. That is, the air pump 1 is not mounted so that its entirety protrudes forward from the outer body 8, but is mounted by being partially inserted into the recess 17 provided in the shoulder member 7, and the amount of protrusion is reduced accordingly. It's summery. In addition, in order to increase safety, the bottom member 9 may be provided with supporting legs 52 that protrude forward.

Although the spout 2 does not necessarily need to be on the center line 1, it is disposed near the center line 1 in front of the outer body 8, that is, directly below or near the air pump 1.

Now, if you push down the push plate 3 of the air pump 1, the pressurized air will flow from the air pump 1 to the air tube 4.
0→safety valve device 38→air hole 23→inner container 4, and pressurizes the inside of inner container 4 (see path a in FIG. 4). Furthermore, when the internal pressure of the inner container 4 increases, the liquid in the inner container 4 flows in the order of liquid pumping tube 26 → spout hole 24 → safety valve device 38 → spout tube 42 → spout 2 (i.e., liquid pumping tube 42 → spout 2). Exit passage 22
(see path b in Figure 4).

Note that the airtightness test at the factory before shipping is performed by sucking internal air from the spout 2 with the air vent hole 25 closed.

[Effect of idea]

As described above, in this invention, the spout 2 of the liquid container main body A is provided directly below or near the air pump 1, so that the operating portion of the air pump 1 and the spout 2 are close to each other. Therefore, the hand operating the air pump 1 and the hand supporting the tea utensil or the like below the spout 2 are brought closer to each other, making it easier to pour liquid.

In addition, if the air pump 1 is provided in the front part of the shoulder member 7 as in the embodiment, the height of the pot can be lowered. In addition, the air pump 1 is connected to the shoulder member 7.
By storing it in the space 49 of the pump cover 43 that covers the recess 17 of the pump, the whole can be made compact. Further, by providing the liquid pouring passage 22 separately from the stopper 12, the liquid supply port 16 can be opened simply by removing the stopper 12, which has the effect of facilitating liquid replenishment and draining operations.
