。Further, the cylindrical valve stem 16, which is slidably fitted into the gas supply member 15, functions as a gas hole cover portion 16a whose upper edge of the cylindrical portion closes the horizontal gas hole 15b. The upper end of the cylindrical portion is in close contact with the sealing member 23 on the inner surface of the cap 11, which is urged downward by the spring 19, so that the high-pressure gas G in the tank 8 is supplied when the illustrated nozzle is inactive. It is prevented from escaping to the outside through the center hole 15a of the member 15 and the vent tube 20.

そして、このバルブステム１６の下端は漏斗状に下方に

形成された弁座２７に対し密着させ、タンク８の液体り
が液通路２６内へ流出するのを遮断している。The lower end of the valve stem 16 is formed as a valve body 16b that expands downward in a funnel shape, and an annular seal member 24 provided on the lower surface of the valve body 16b is connected to the upper end of the inner circumferential cylindrical portion 25 of the annular throat portion 11. The valve seat 27 surrounds the liquid passage 26 and is brought into close contact with a raised valve seat 27 to prevent the liquid in the tank 8 from flowing into the liquid passage 26.

謂ガス詰め作動を行わせることができる。Therefore, the valve stem 16 is in the non-operating position shown in the figure, where it is pushed down by the gas supply member 15 urged downward by the spring 19 and closes the gas hole 15b and blocks the lower liquid passage 26. Since the valve stem 16 is simultaneously under the pressure of the high-pressure gas G and liquid, if the gas supply member 15 is raised against the spring 19 by an external force, the valve stem 16 will move against the valve seat 2.
1 to prevent the liquid from flowing out,
In addition, the gas supply member 15 can perform a so-called gas filling operation in which the gas hole 15b rises above the gas hole cover 16a and the high-pressure gas G is led out through the gas hole 15b, the center hole 15a, and the vent tube 20. .

行わせることができる。Therefore, in the illustrated non-operating position where the pressure of the high-pressure gas G is applied and during the above-mentioned gas filling operation, the valve stem 16 maintains its seated position relative to the valve seat 2T, but acts on the lower surface of the valve body 16b. When the pressure approaches the same pressure as the high-pressure gas G, the valve stem 16 automatically rises and opens to introduce the liquid in the tank 8 into the liquid passage 26, thereby performing a so-called liquid filling operation.

行なうことができる。As described above, the device of the present invention is capable of handling the container receiving member 32, the gas supply member 15, and the valve stem 1 as the container E moves up and down.
Since gas filling, liquid filling, and the snifting action are automatically performed using the relative vertical movement of the valve 6, it is possible to perform the snifting action without using a complicated snift valve mechanism as in the past. Further, gas filling can be performed without providing a special valve mechanism such as a gas filling valve mechanism.
