Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a pump-filling type liquid container, and more specifically to a pump-filling type liquid container in which an air pump is installed at the bottom of the liquid container body. be.

(Technical background of the invention) In a pump liquid container of the type in which an air pump is provided on the liquid container main body side and pressurized air from the air pump is guided to the upper part of the liquid container through an air supply pipe, When guiding the air pipe to the liquid container side, a part of the air pipe becomes easily exposed to the outside.
There was a problem in that if the air pipe was exposed to the outside, it would look bad.

In addition, among the known pump liquid containers of this type in which an air pump is provided at the lower part of the liquid container body, there are, for example, those disclosed in Japanese Utility Model Application Publication No. 57-27228 or No. 50-9875. There is something to be shown. By the way, in the above-mentioned Utility Model Application Publication No. 57-27228,
The tip of the air supply pipe led upward from the air pump is communicated with the inside of the liquid supply port near the bottom of the lip of the liquid supply port (sealed by the stopper). Although the connection structure of the air pipe can be simplified by connecting only the side to the liquid supply port, if too much liquid is poured into the liquid container during liquid supply (the liquid is not supplied until it reaches the upper edge of the liquid supply port) When this occurs, there is a problem that some of the supplied liquid may flow into the air pump through the air supply pipe. In addition, in the one disclosed in Japanese Utility Model Application Publication No. 50-9875, the upper end of the air pipe is guided upward through the shoulder member of the liquid container body, and is further connected to the upper end of the air passage inside the stopper. The upper end opening is positioned above the upper end edge of the liquid supply port, but in the case of this Japanese Utility Model Application No. 50-9875, the air supply pipe is connected to the upper surface of the liquid container main body and the lower surface of the lid above it. When the lid is opened, the exposed part of the air pipe is visible from the outside, resulting in a poor appearance, and there is a risk that other items may get caught on the exposed part of the air pipe, causing damage to the air pipe. There is a problem.

(Purpose of the invention) In view of the above-mentioned problems with conventional pump-filled liquid containers of the same type, the present invention was designed to guide pressurized air from an air pump provided on the liquid container body side to the liquid container side through an air supply pipe. To prevent the air pipe from being exposed to the outside in a pump-type liquid container with a swinging type, so that the appearance does not deteriorate, and to protect the air pipe.
Moreover, it is an object of the present invention to provide a pump-filling type liquid container that prevents the excess liquid from flowing into the air supply pipe even when too much liquid is filled during liquid supply.

(Structure of the invention) The present invention uses a hinge device to pivotally attach a lid body with an upper and lower double wall structure having an upper plate and a lower plate to the upper part of a liquid container main body which houses a liquid container in an outer case. Pressurized air from an air pump installed at the bottom of the liquid container body is blown into the liquid container through an air blowing passage, and the pressurized air causes the liquid in the liquid container to be discharged to the outside through a series of liquid pouring passages. In the pump-type liquid container capable of dispensing liquid to the liquid container, an air supply pipe constituting a part of the air blowing passage is guided upward from the air pump side through between the outer case and the outer surface of the liquid container. Furthermore, from the hinge device side, through between the upper plate and the lower plate of the lid body, further from the lower plate of the lid body, it is connected so as to be freely connected and detached to an air passage in the plug provided in the plug that closes the liquid supply port of the liquid container main body. It is characterized by what it did.

(Function) According to the present invention, the air supply pipe is passed between the outer case and the outer surface of the liquid container, and is connected to the air passage inside the stopper from the hinge device side through between the upper plate and the lower plate of the lid. Even when the lid is open, the air pipe is not exposed to the outside, and the opening on the tip side of the air pipe is located above the upper edge of the liquid supply port.

The lower end opening of this connecting pipe 76 is connected to the upper opening 25a of the in-plug air passage 25 of the plug 21 so as to be freely accessible and detachable.

In this way, the air supply pipe 46 is passed through the space between the outer case 4 and the outer surface of the liquid container 5, and the hinge device 5
If it is installed by passing between the upper plate 2a and lower plate 2b of the lid body 2 from the 0 part, the upper end opening side of the air supply pipe 46 (lower end opening of the connecting pipe 76) will be closer to the upper end edge of the liquid supply port 7. It is now located at the top of the air pipe 4, so even if too much liquid is added during liquid supply, the liquid will be
Since the air pipe 46 is entirely housed within the liquid container body 1 and the lid 2, the air pipe 46 is not exposed to the outside even when the lid is open. This improves the appearance, and also eliminates the problem of other articles accidentally coming into contact with the air pipe 46 and damaging the air pipe 46. Note that the liquid container receiving member 1
2 and the upper flange 32 of the pump case 13 are formed with holes 34 and 35 that overlap each other, respectively, and the air supply pipe 46 is inserted through the holes 34 and 35 in the vertical direction.

A base end 18a of a pump operating lever 18 for pressing the air pump 8 is pivotally attached to the inner surface of the body 31 of the pump case 13 by a pin 17. The tip 18b side of the pump operating lever 18, which serves as the operating section, protrudes to the outside through a window hole 36 vertically formed in the pump case body 31.
By pressing 18b downward, the air pump 8 can be contracted as shown by the chain line 8'. An elongated hole 61 is formed in the middle portion of the pump operating lever 18, and a shaft 63 of a roller 62 is fitted into the elongated hole 61. The upper surface 41a of the suction valve 41 is an arcuate surface for receiving the roller 62.

2 is integrally formed with a tongue-shaped suction valve 41 that opens and closes the pump suction port 40. By attaching the single member 72 in which the pump suction port 40 and the pump discharge port 42 are respectively formed to the air pump 8 in this way, it is possible to install the single member 72 in which the pump suction port 40 and the pump discharge port 42 are formed separately, instead of forming the pump suction port 40 and the pump discharge port 42 separately as in the conventional case. In comparison, only one hole needs to be formed on the air pump side (for example, the pump upper plate 37), and the pump suction port 40
Also, a member for forming the pump discharge port 42 can be shared.

In the air pump 8 in the pump-filling liquid container of the fourth embodiment, a hook valve type that moves up and down with respect to the pump suction port 40 is provided at the pump suction port 40 formed approximately in the center of the pump top plate 37.

In the case of the fourth embodiment as well, the configuration for forming the pump suction port 40 and the pump discharge port 42 in the air pump 8 can be simplified as in the third embodiment.

The fifth embodiment shown in FIG. 5 and the sixth embodiment shown in FIG.
Each of the pump injection type liquid containers of the embodiment shows a modification in which the tip (upper side) of the air supply pipe 46 is connected to the upper part of the liquid container 5.

In the pump liquid container of the fifth embodiment shown in FIG. 5, the air supply pipe 46 is divided into two parts: a lower air supply pipe 77 provided on the liquid container main body 1 side and an upper air supply pipe 78 provided on the lid body 2 side. The lower air pipe 7
The tips 77b of 7 are airtightly communicated with each other when the lid is closed. That is, at a position near the hinge device formation of the lower opening member 6, there is a connecting pipe 79 penetrating vertically.
A connecting pipe 80 is provided at a position corresponding to the lower opening member side connecting pipe 79 on the lid lower plate 2b when the lid is closed, and the connecting pipe 80 communicates with the lower opening member side connecting pipe 79 in an airtight manner. There is. The lower air supply pipe 77 has its tip (upper end) 77b connected to the lower mouth member side connecting pipe 79.
The upper air supply pipe 78 is connected to the lower part of the lid body 2 and between the lower plates 2a and 2b.
a is connected to the upper part of the connecting pipe 80 provided on the lower plate 2b, and its tip 78b is connected to the in-stop air passage 2.
It is connected to a connecting pipe 76 that can communicate with the upper opening 25a of No. 5. Therefore, the upper and lower air supply pipes 78 and 77 are in airtight communication with each other when the lid body 2 is closed, and the distal end side of the air supply pipe 46 (the connecting pipe 7
6) is airtightly communicated with the in-stop air passage 25 to form a series of air blowing passages 9. By dividing the air supply pipe 46 into upper and lower halves in this way, even if the lid body 2 is configured to be detachable from the liquid container body 1 with a pump liquid container, the air supply pipe 46 can be separated from the lid body 2 side. It can be installed via In the embodiment shown in FIG. 5, a tongue-shaped water stop valve 81 for opening and closing a passage within the connecting pipe 78 is formed on the connecting pipe 78 on the side of the lower mouth member. This water stop valve 81 is closed when the pump is stopped, so that even if the liquid container 5 is accidentally overturned and the liquid in the liquid container 5 flows through the in-stop air passage 25 and the upper air supply pipe 78, The liquid is blocked by a water stop valve 81 to prevent it from flowing any further to the air pump 8 side. Note that this water stop valve 81 is opened by pressurized air forced through the lower air supply pipe 77 when the pump is operated.

The pump injection type liquid container of the sixth embodiment shown in FIG. 6 is a modification of the one shown in FIG. A lower opening edge 82a of a communicating hole 82 that closes when the lid is opened and is provided in the lid lower plate 2b when the lid is closed, in the tube 78.
A valve 83 is provided which is pressed open by the pressure. This valve 83 has the function of preventing water, dust, etc. from entering the air pump side from the connecting pipe 78 on the lower mouth member side when the lid is opened.

In each of the embodiments shown in FIGS. 2 to 6, the omitted parts are constructed in the same way as the pump injection type liquid container shown in FIG. 1, and the parts shown in FIGS.
In the drawings, the description of the pump-type liquid container shown in FIG. 1 will be referred to for parts designated by the same reference numerals as in FIG. 1 and whose explanations are omitted.

(Effects of the invention) The present invention provides a pump injection type liquid container in which pressurized air is guided from the air pump 8 installed at the lower part of the liquid container main body 1 to the liquid container 5 side through the air supply pipe 46. The air supply pipe 46 is passed between the outer case 4 and the outer surface of the liquid container 5, and is connected to the hinge device 5.
Since the air passage 25 is connected from the lower plate 2b of the lid 2 to the air passage 25 in the plug through the upper plate 2a and lower plate 2b of the lid 2 from the 0 side, the opening of the tip of the air pipe 46 is above the liquid supply port 7. It is located above the edge of the end opening, so that even if liquid is accidentally poured until it reaches the edge of the upper end of the liquid supply port 7 during liquid supply, the liquid will not flow into the air supply pipe 46 side. In addition to being effective, even when the air pipe 46 is installed with the lid side bypassed, the air pipe 46 is not exposed to the outside even when the lid is opened, resulting in a good appearance. This has the effect of preventing the problem of other objects coming into contact with the air pipe 46 and damaging the air pipe 46.
