PURPOSE:To prevent the formation of a noxious reaction product, by flowing gas to a gas introducing pipe and a gas discharge pipe in a short-circuited state when a reactive liquid is hermetically sealed in a container to exhaust the liquid vapor remaining in the arranged pipe of the gas discharge pipe side. CONSTITUTION:The titled container is constituted of a container main body 21, a valve body 25 provided with a gas introducing port 31 and a gas exhaust port 32 and a container sealing part 24 equipped with rising movable valves 26, 27. In addition, each movable valve is separated into two upper and lower valves 26, 27 while piercing orifices 33, 33' are provided to the two valves 26, 27. Further, two valves 26, 27 are connected by bellows 37 and the gap 34 formed by this mechanism forms an introduced gas passage along with the piercing orifices 33, 33'. For example, when the discharge of the liquid in the main body 21 is stopped, a rod 28 is pushed down and the valve 27 is brought into close contact with the body 25 while the corners of the opposed recessed and protruded parts of the valves 26, 27 are closely contacted. By this mechanism, a short circuit course from the gas introducing port 31 to the exhaust port 32 is formed. |
