The lower end of the linking member 21 passes through the bottom plate 23 of the lid 2 and comes into contact with the upper surface of the valve body 18 when the lid is closed. Further, the upper end of the linking member 21 is in contact with the lower surface of the operating portion 10a of the operating member 10. That is, the valve body 18 and the operating member 10 are linked via the linking member 21 so as to be interlockable.

In addition, in FIGS. 1 to 3, reference numeral 24 is a suction valve of the air pump 9, 25 is a gasket interposed at the connection between the communication pipe 15 and the spouting pipe 16, and 26 is a pipe that covers the spouting pipe 16. It's a cover.

Next, the operation of the siphon type air pot of the first embodiment will be explained.

When the air pot is not in use, the valve part 1 of the valve body 18
8a is always seated on the valve seat 19 and closes the pouring passage 17. Therefore, even when falling, the internal liquid W
There is no risk of leakage.

When the air pump 9 is pressed and driven by pressing the operating portion 10a of the operating member 10, the pressurized air from the air pump 9 is fed into the liquid container 3, and at the same time, the pressurized air is transferred to the valve body via the linking member 21. 18 is moved under pressure to open the pouring passage 17 (see FIG. 3). Therefore, the liquid W in the liquid container 3 is continuously poured out to the outside through the pouring passage 17 due to the siphon effect.

When the pressing force of the operating member 10 to the operating portion 10a is released after obtaining the desired pouring amount, the operating member 10 returns to the state shown in FIG. The pressing force on the body 18 is released, and the valve body 18 enters the closed state. Therefore, the pouring passage 17 is closed and pouring is stopped. After that, the liquid pumping pipe 14, the circular plug liquid passage 8 and the communication pipe 1
The liquid W in 5 flows back into the liquid container 3, and will not be poured out unless the air pump 9 is driven again.

FIG. 4 shows a second embodiment of the present invention, in which an air supply port 2 is provided at the tip of the upper wall of the communication tube
7 and the air supply port 27 is connected to the valve stem portion 1 of the valve seat 18.
