Description

[Detailed description of the invention] (Industrial application field) The present invention is a liquid injection pump that enables liquid in an inner container to be poured out to the outside through a series of liquid injection passages using pressurized air from a pump device. The present invention relates to a type liquid container.

(Prior Art) In conventional pump-type liquid containers of this type, the pump device is built into the lid, which increases the height of the lid as a whole.
There was a problem that the height of the entire liquid container became high.

In addition, in this type of general pump injection type liquid container, a series of liquid dispensing passages for guiding the liquid in the inner container to the outside are inserted into the inner container into a stopper that opens and closes the liquid supply port. It is constructed by integrally attaching a downward liquid pumping pipe and a horizontal liquid pouring pipe provided outside the inner container. However, when the liquid pumping pipe and the liquid pouring pipe are integrally attached to the stopper, a long series of liquid pouring passages must be removed from the liquid supply port when refilling the liquid. The handling of the liquid pouring passage has become troublesome.

In addition, some known pump injection type liquid containers have a structure in which a vertical liquid pumping pipe 111 and a horizontal liquid dispensing pipe 112 are connected, for example, as shown in FIG. - A device is known in which the pump device 112 is divided so as to be separable and is integrally formed on the bottom plate 109a of the pump device 109 provided on the side of the lid 102. In this known device, the liquid pouring tube 112 can be separated from the liquid pumping tube 111 at the same time as the lid 102 is opened and closed, which simplifies the operation when replenishing liquid. Since it is built in 102,
As the height of the entire lid increases, the liquid pouring pipe 112 must be integrally formed on the bottom side of the pump bottom plate 109a (because the bellows 109b of the pump device 109 is located on the top side of the pump bottom plate 109a, the liquid pouring pipe 112 must be formed integrally with the bottom side of the pump bottom plate 109a). (The pipe 112 cannot be provided on the upper surface side of the pump bottom plate 109a), therefore, the lid body 1
There was a problem that the overall height of 02 (the overall height of the liquid container) became high.

(Purpose of the invention) In view of the above-mentioned problems with conventional pump-filling liquid containers, the present invention has been developed to reduce the height of the entire liquid container by keeping the height of the lid low. We propose a pump-filling type liquid container in which the pumping pipe and the liquid spouting pipe are separated, making it easier to handle the liquid spouting pipe when replenishing liquid, and making effective use of the space inside the lid. The purpose is to

(Means for achieving the object) A lid body is provided on the upper part of a liquid container main body formed by housing an inner container in an outer case, and the liquid in the inner container is further pumped into the inner container by pressurized air from a pump device. In a pump injection type liquid container capable of pouring out to the outside through a series of liquid pouring passages having a liquid pumping tube to be inserted and a liquid pouring tube provided outside the inner container, the pump device is configured to The liquid pumping tube and the liquid pouring tube are separated so that they can be connected and separated from each other, and the liquid pouring tube is connected to the liquid pouring tube. It is characterized in that it is attached to the lid while being built into the lid.

(Function) The pump injection type liquid container of the present invention has the pump device installed in the space between the outer case and the inner container at the shoulder of the liquid container body, so it is not necessary to provide the pump device on the lid side. The height of the lid body can be kept low, and the liquid pumping pipe and the liquid spouting pipe are separated from each other, and the liquid spouting pipe is installed inside the lid body. At the same time as opening and closing the lid, the liquid spouting pipe can be removed or the liquid spouting pipe can be connected to the liquid pumping pipe.

The exterior body 3 has an outer shell 4 and a dish-shaped annular shoulder member 5 placed and fixed on the upper part of the outer shell 4.

The inner container 6 is a vacuum-insulated double bottle made of glass. The upper opening 6a of the inner container 6 is narrowed into a narrow neck shape, and an annular space 7 with a fairly large volume is formed between the upper surface of the shoulder portion 6b of the inner container 6 and the lower surface of the shoulder member 5. has been done. This annular space 7 is normally a space that is hardly used.

The pump device 9 includes an annular cover body 24 that covers the inner and outer edges of an annular membrane material 23 formed of a flexible material such as rubber or soft synthetic resin and having a U-shape in cross section. and an annular support frame 25 with a U-shaped cross section, which are airtightly sandwiched.
An airtight chamber 2 is provided between the annular membrane material 23 and the cover body 24.
2 is formed. And this pump device 9 is
It is fixed to the lower surface of the shoulder member 5 with screws 26, 26 while being accommodated in the space 7 formed between the upper surface of the shoulder portion 6b of the inner container 6 and the lower surface of the shoulder member 5. By installing the pump device 9 in the relatively unused space 7 in this manner, the space 7 can be effectively utilized.

This pump device 9 is adapted to be pressed and operated from below by a lever-type pump operating member 41. This pump operating member 41 has bifurcated pump pressing parts 43, 43 on the inner side, and has an operating part 42 that can be operated from the outside on the outer side, with a shaft 44 connecting the intermediate part.

It is becoming more and more occluded. Note that when the valve 37 moves upward during pump operation to open the annular packing inner passage 33a and simultaneously close the through hole 36, the series of air blowing passages 31 are communicated, and the stress generated in the airtight chamber 22 is removed. Pressurized air is blown into the inner container 6 through the air blowing passage 31.

A series of liquid pouring passages 10 for guiding the liquid in the inner container 6 to the outside includes a vertical liquid pumping tube 11 inserted into the inner container 6, and an intra-stopper liquid passage 14 provided inside the stopper 8. , a sideways liquid spouting pipe 12 and a spouting auxiliary pipe 13.

The liquid pumping tube 11 is fixed to a portion near the outer periphery of an annular frame 51 having a relatively large opening 52 (actually serving as a liquid supply port in this embodiment) into which liquid can be supplied. This annular frame body 5 with a liquid pumping pipe
1 can be detachably attached to the liquid supply port 21 of the shoulder member 5 by means such as helicoid coupling, and the annular frame 51 with a liquid pumping pipe is designated by the reference numeral 51' (FIG. 4). As shown, the liquid pumping tube 11 can be removed from the liquid supply port 21 and cleaned individually if necessary. In addition, when the annular frame 51 is attached, the liquid pumping pipe attachment portion is located on the front side.

An annular packing 15 is provided at the lower end of the liquid passageway 14 in the stopper, which contacts the upper end edge of the liquid pumping pipe 11 when the lid is closed, and makes the liquid drawing pipe 11 and the liquid passageway 14 in the stopper watertight when the lid is closed. It is designed to communicate with

In the pump injection type liquid container of this embodiment, when the operating part 42 of the pump operating member 41 is pushed down in the closed state, the pump device 9 is operated and the pressurized air is passed through a series of air blowing passages 31 to the contents. vessel 6
The pressurized air blows into the inner container 6.
The liquid inside passes through a series of liquid pouring passages 10 and is poured out from the lower end discharge port 13a of the auxiliary pouring pipe 13.
Furthermore, when replenishing liquid into the inner container 6, the opening 52, which essentially serves as a liquid supply port, can be opened by simply opening the lid 2, and the liquid can be refilled from the opening 52.

(Effects of the invention) The pump injection type liquid container of the invention has the following effects.

(1) Since the pump device 9 is installed in the space 7 between the exterior body 3 and the inner container 6 on the shoulder of the liquid container body 1, the space 7, which is not used much, can be effectively utilized. can.

(2) With the configuration (1) above, there is no need to provide the pump device 9 inside the lid 2, so the height of the entire lid 2 can be reduced, thereby making the entire liquid container compact.

(3) Separate the liquid pumping pipe 11 and liquid pouring pipe 12,
Moreover, since the liquid spouting pipe 12 is attached to the lid 2, the liquid spouting pipe 12 can be handled together with the lid 2, making the operation at the time of liquid replenishment easy.

(4) Since the liquid pouring pipe 12 is installed inside the lid 2, when the pump device 9 is installed on the shoulder of the liquid container body 1, it can be installed inside the lid 2, which is not often used. Fill the empty space with liquid dispensing pipe 1
