[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air pump injecting device, in which pressurized air from an air pump housed in a lid is blown into a liquid container and the liquid pressure in the liquid container is discharged from the outside by the air pressure. The present invention relates to an improved liquid container.

[0002]

2. Description of the Related Art FIG. 4 shows one of conventional examples of this type of air pump injection type liquid container. In this conventional air pump injection type liquid container, the air pump 5 housed in the lid 4 is pushed down by a pump push plate 6 to blow pressurized air into the liquid container 1 to make a series of liquids in the liquid container 1. The liquid is poured out through the liquid pouring passage 7. In the case of this conventional example, the pump push plate 6 is housed in a cylindrical hole (guide chamber) 20 formed at substantially the center of the lid body 4 for guiding the pump push plate 6, and the pump push plate 6 is the same. Peripheral wall of the guide room 20
It is guided by the (guide wall) 21 and moved vertically.

Further, in the conventional air pump injection type liquid container as illustrated in FIG. 4, when the liquid injection operation is not performed,
In order not to push down the pump push plate 6,
It is customary to provide the stopper ring 9 on the outside of the guide wall 21. The stopper ring 9 is rotated in the left-right direction by a knob 9a so that the tab 9 is formed at the lower end of the stopper ring 9.
The fact that b is engaged with or disengaged from the lower end 6b of the pump push plate 6 is used to restrict or allow the push-down operation of the pump push plate 6.

By the way, as the diameter of the air pump 5 increases, a large amount of pressurized air can be blown into the liquid container 1 with a shorter stroke, but on the other hand, a large operating force is required to drive the liquid container 1 by pushing it down. Is required. on the other hand,
The air pump 5
The smaller the diameter of, the larger the required pump stroke will be.

[0005]

By the way, if the pump stroke S is simply increased, the height h of the lid 4 may be increased and the longitudinally long air pump 5 may be accommodated. If S is made too large, when the pump push plate 6 is pushed down this time, the pump push plate 6 lowers below the lower end 21a of the guide wall 21 and the inside of the lid 4 is exposed. on the other hand,
To avoid this problem, if the length of the guide wall 21 is increased, the lower end 6b of the pump push plate 6 is also engaged with the claw 9b of the stopper ring 9 located immediately below the lower end 21a of the guide wall 21. There is no choice but to lower it to the position of 9b, and accordingly, there is a room for pushing down the pump push plate 6, that is, a pump stroke becomes small.

According to the present invention, when the diameter of the air pump 5 is reduced (long stroke) in order to reduce the pump operating force of the air pump 5, the above-mentioned "exposure of the inside of the lid body" is performed.
The purpose of the present invention is to achieve a long stroke of the air pump without causing the above problem, and further, while the pressing action of the air pump 5 by the stopper ring 9 can be restricted.

In summary, it can be said that the following problems (a) to (c) are set in the present invention.

(A) The price of reducing the diameter of the air pump 5 is to increase the pump stroke (to achieve this, the lower end 6a of the pump push plate 6 or the pump top plate 34 is positioned as high as possible, and the pump push plate 6 Or pump top plate 34
Leave as much room for downfall as possible).

(B) In order to prevent the inside of the lid 4 from being seen from the outside even if the pump stroke (stroke of pushing down the pump pushing plate 6) becomes large, some kind of shielding wall member extending downward is provided.

(C) A lid inner shielding wall member extending downward is provided, and even if the lower end 6a of the pump push plate 6 (or the pump top plate 34) becomes higher, it is located outside the guide wall 21. The stopper ring 9 prevents the air pump from being pushed down (from below, the pump push plate 6 or the pump top plate 3
4 function to support 4).

[0011]

The present invention has been made for the purpose of achieving the above-mentioned object, and as shown in FIGS. 1 to 3, an air pump 5 housed in a lid 4 is provided. Is vertically guided in the guide chamber 20 formed in the lid body 4, and when pressurized air is blown into the liquid container 1 from the air pump 5, the liquid in the liquid container 1 is continuously discharged. A guide wall 2 forming the guide chamber 20 while allowing it to be poured out through the passage 7.
1 which is fitted in 1 and is rotated by a predetermined angle in the left-right direction, engages with or disengages from the pump push plate 6 to regulate the downward movement of the pump push plate 6 or allow the downward movement. A parring 9 is provided, and the stopper ring 9 exposes the inside of the lid 4 from a gap between the guide wall 21 and the pump push plate 6 formed at the lowermost operation position of the pump push plate 6. It is characterized in that a shielding wall member 60 for shielding the above is formed.

[0012]

In the air pump injection type liquid container of the present invention, the stopper ring 9 normally prevents the air pump from being pressed. Therefore, when the liquid is to be discharged, the stopper ring is first used. The air pump 5 can be pressed by rotating 9 by a predetermined angle. Then, when the pump push plate 6 is pushed down in this state, the air pump 5 is compressed and pressurized air is blown into the liquid container 1, and the liquid in the liquid container 1 is discharged to the outside through a series of liquid discharge passages 7. To do.

In the present invention, since the outer diameter of the air pump 5 is smaller than the inner diameter of the guide wall 21, the pump operating force by the pump push plate 6 may be relatively small, but the pump stroke is correspondingly large. . If the pump stroke of the air pump 5 becomes large, the lower end of the pump push plate 6 and the guide wall 21 (or an appropriate vertical groove formed in the guide wall 21 if necessary) should be provided in the latter half of the pump stroke. Although there is a concern that the inside of the lid body 4 can be seen from between the and, the shield wall member 60 formed on the stopper ring 9 prevents such a problem in the present invention.

[0014]

Therefore, according to the present invention, since the inside of the lid 4 is not exposed even if the pump stroke is increased, the required pump stroke is set to reduce the diameter of the air pump, that is, the pump. A reduction in operating force can be achieved.

[0015]

1 and 2 show an air pump injection type liquid container according to a first embodiment of the present invention. In FIG. 1, reference numeral 1 is a liquid container formed of a vacuum double bottle, 2 is an exterior body, 3 is a shoulder member, and 4 is a lid. An air pump 5 is housed in the lid body 4. A circular guide chamber 20 for accommodating and guiding the pump push plate 6 for operating the air pump is formed in a substantially central portion of the lid body 4. A peripheral wall (guide wall) 21 of the guide chamber 20 pushes the pump. The vertical movement of the plate 6 is guided. That is, four vertical ribs 43, 43 are formed on the outer peripheral surface of the pump push plate 6 at intervals of 90 °.
.. and vertical grooves 23, 23 formed in the guide wall 21.
The pump push plate 6 can be smoothly moved up and down by sliding in the up and down direction. The pump push plate 6 has an upper end surface 43a of each vertical rib 43.
Is abutted against the upper end surface 23a of each vertical groove 23 so that the upward movement is restricted.

A bellows type air pump 5 is provided in the lid 4, and the body diameter of the air pump 5 is smaller than that of the pump push plate 6. An intake port 35 is formed in a central portion of a top plate 34 of the air pump 5, and the intake port 35 is opened and closed by an intake valve 36 with a hook leg 36a. The upper end of a compression coil spring 37 is abutted against the suction valve 36 from below, and the pump spring 37 passes through the hook leg 36 a of the suction valve 36 and the pump top plate 34.
Is biased upward.

By the way, in the air pump 5 used for the air-pump injection type liquid container as shown in FIG. 1, since the vapor from the liquid container 1 always flows in, the pump top plate 34 is lifted by the vapor pressure as it is. As a result, the suction port 35 is naturally closed, and the liquid in the liquid container 1 is naturally poured out, which causes a problem. Therefore, in the conventional example shown in FIG.
The pump top plate 34 is pressed by the lower end 21a of the guide wall 21 to prevent the pump top plate 34 from rising naturally.

However, in the air pump injection type liquid container of the embodiment shown in FIG. 1, the entire pump top plate 34 is the guide wall 2.
Since it is located inside 1, the pump top plate 34 cannot be prevented from rising by the method as in the conventional example shown in FIG. Therefore, in the embodiment shown in FIG. 1, the intermediate float body 8 as described below is used.

The intermediate float body 8 has a cylindrical body portion 45 that surrounds the outside of the bellows 32 of the air pump 5.
Has a flange 46 at its lower end. On the other hand, the body portion 45 has vertical grooves 49, 49 formed therein.
Claw pieces 39, 39 projecting laterally from the pump top plate 34 are engaged therein. Then, in the most expanded state of the air pump 5, the flange 46 of the intermediate float body 8 engages with the lower end 21a of the guide wall 21, and the claw 39 of the pump top plate 34 is locked at the upper end of the vertical groove 49 to pump the pump. The top plate 34 can be prevented from moving upward. A stopper ring 9 is provided on the outer periphery of the guide wall 21. The stopper ring 9 is supported in the lid 4 from below by three to six stopper ring receivers 29, and is rotated by a knob 56, whereby the inner surface of the inner peripheral wall 57 of the stopper ring 9 is rotated. The receiving pieces 58, 58 integrally formed at the middle position are the vertical ribs 43, 43 of the pump push plate 6.
Can be located below (the air pump 5 cannot be operated) or can be removed from below the vertical ribs 43, 43 of the pump push plate 6 (the air pump 5 can be operated). In this case, the receiving pieces 58, 58 of the stopper ring 9 have the vertical ribs 43, 43 of the pump push plate 6 located at a high position in the guide wall 21.
Since it is located at the same height as the notch 24,
Is provided so as to project from the notch 24 inward of the guide wall 21. By the way, since the notch 24 is in the middle of the pressing stroke of the pump push plate 6, the notch 2 should normally be in the middle of the pressing operation of the pump push plate 6.
The inside of the lid 4 comes to be exposed from 4,
In this embodiment, the present invention is applied to the stopper ring 9
The inner peripheral wall 57 is elongated downward to form a shielding wall member 60 that covers the cutout 24.

When using the air pump liquid injection type liquid container of the first embodiment shown in FIG. 1 to discharge the liquid in the liquid container 1, first, the stopper ring 9 is rotated to push down the pump push plate 6. The state is made possible (the receiving piece 58 of the stopper ring 9 located in the notch 24 of the guide wall 21 is laterally displaced from the position directly below the vertical rib 43 of the pump push plate 6). Next, when the pump push plate 6 is pushed down, pressurized air is blown into the liquid container 1 and the liquid in the liquid container 1 is discharged to the outside through a series of liquid discharge passages 7. At this time, the intermediate float body 8 also descends together with the pump push plate 6, but after the flange 46 of the intermediate float body 8 has bottomed on the pump bottom plate 31, only the pump push plate 6 descends.

In the expansion stroke of the air pump 5, the pump spring 37 lifts the pump top plate 34 and the pump push plate 6 via the suction valve 36 to expand the air pump 5. When the pump push plate 6 rises to a certain height, the tab 3 of the pump top plate 34
9 hooks the intermediate float body 8 and lifts it upward. When the intermediate float body 8 rises and its flange 46 abuts against the lower end 21a of the guide wall 21, the intermediate float body 8 and the pump top plate 34 hooked by the intermediate float body 8 stop rising, and the intake port 35 is maintained open. It

FIG. 3 is a development view of the main members of an air pump injection type liquid container according to the second embodiment of the present invention. In this embodiment, the shield wall member 60 of the inner peripheral wall 57 of the stopper ring 9 has the same diameter as the guide wall 21, and the guide wall 21 and the shield wall member 60 form a vertically continuous cylindrical wall body. I am trying. That is, in this embodiment, the guide wall 21 is made shorter than that of the first embodiment of FIG. 1 so that the shield wall member 60 of the stopper ring 9 is located immediately below the guide wall 21, and the guide wall 21 Vertical groove 23 for guiding the pump push plate vertical rib formed on the side
A vertical groove 63 for guiding the pump pressing plate rib 43 is also formed on the stopper wall 9 side of the stopper ring 9 so as to be continuous with the above. That is, in this embodiment, the vertical ribs 43, 43 of the pump push plate 6 are vertically guided over the vertical groove 23 of the guide wall 21 and the vertical groove 63 of the shielding wall member 60 of the stopper ring 9.

A boundary between the inner peripheral wall 57 on the upper side of the stopper ring 9 and the shielding wall member 60 on the lower side is a shelf 59, and when the stopper ring 9 is rotated, the shelf 59 is pushed by the pump pushing plate. 6 may be located directly below the vertical ribs 43 of the pump 6 (the pump pressing plate 6 cannot be pushed down), or the vertical groove 63 of the stopper ring 9 may be located directly below the vertical ribs 43 of the pump pressing plate 6 (the pump pressing plate 6). 6 can be pushed down).

In the case of this embodiment, the guide wall 21 and the shield wall member 60 of the stopper ring 9 form a vertically continuous cylindrical wall body, and moreover, like the notch 24 in the first embodiment of FIG. Since there is no such thing, the inside of the lid body 4 is not exposed in the middle of the pushing stroke of the pump push plate 6.

The intermediate float body 8 is also used in this second embodiment, but its operation is similar to that of the first embodiment, and therefore its explanation is omitted.
