It passes through a series of liquid passages 30 and is poured out from the spout pipe 13 to the outside.

When you release your hand from the pump operation plate 9, the air pump 8 is expanded by the extension spring 49, the pump operation plate 9 returns to its original position, and the pressing force of the push rod 53 is released from the valve body 36, causing the valve body push-up spring 39 to be released. The valve portion 38 closes the communication port 23 by being pushed up.

In addition, in this pump injection type liquid container, the upper packing 25 and the body packing 26 attached to the stopper 21 function as airtight and watertight, respectively, so that the pressurized air from the air pump 8 leaks or is forced out to the outside. The liquid in the liquid container does not leak to the outside from the middle of the series of liquid passages 30.

Also, when the air pump 8 is at rest, the valve body 36 is closed to the communication port 2.
3 is always closed, even if the liquid container is accidentally overturned, the liquid W in the liquid container will not leak out from the spout pipe 13 through the series of liquid passages 30, and the liquid passage 3
Since outside air does not flow into the liquid container 6 through 0, it is possible to prevent the heat retention ability from decreasing.

Further, as in the illustrated embodiment, if a valve body 36 for opening and closing the water passage 22 in the plug is installed and the valve body 36 is opened and closed in conjunction with pump operation, the water passage inside the plug can be opened and closed. 22 can be opened and closed simultaneously with pump operation, thereby
To prevent the liquid in the liquid container from leaking to the outside through the liquid passage 30 when the liquid container falls over, and to prevent a drop in heat retention ability for the liquid in the liquid container by eliminating heat radiation from the liquid passage 30. be able to.

Next, to explain the effect of the present invention, the pump injection type liquid container of the present invention has a liquid dispensing pipe 12 in the lower mouth member 7, so that the stopper unit 2 can be connected to the stopper body 21. Since it is possible to form a vertically long configuration with the liquid pumping pipe 10 extending downward, the liquid pouring pipe does not get in the way when the plug unit 2 is inserted into or removed from the plug insertion hole 11, unlike in the conventional case. This has the effect of simplifying its handling without causing any damage.

In addition, the pump injection type liquid container of the present invention has a liquid injection pipe 12.
is exposed to the outside through the space formed between the outer case 5 and the lower mouth member T, so the space, which was rarely used in the past, can be used for installing the liquid spouting pipe 12. In addition to being able to effectively use the space, the liquid spouting pipe 12 is not exposed on the upper surface side of the lower mouth member 7, so even if the liquid spouting pipe 12 is provided in the lower mouth member 7, the liquid There is also the effect that the liquid pouring pipe 12 does not get in the way when hot water is supplied into the container 6 or when residual liquid is discharged.
