INNER STOPPER FOR AIR POT

PROBLEM TO BE SOLVED: To make an internal part washable by making an inner stopper for an air pot separable and to prevent the temperature of a content liquid from being lowered by supplying the content liquid into an inner container without removing the inner stopper. SOLUTION: A cylindrical main body 1 of the inner stopper and an inner stopper lid 2 equipped with an introduction port 5 for pressurized air and an injection pipe 8 for the content liquid can be freely attached and detached. By attaching/detaching the main body 1 of the inner stopper and the inner stopper lid, a liquid injection passage cylinder 11 capable of attaching/detaching a connecting pipe 9 with the liquid injection pipe 8 formed on the inner stopper lid 2 and a safety valve cover 4 for holding a safety valve 6 and a hat-like valve holder 3 forming an air passage partitioned from the liquid injection passage cylinder are held. By separating the main body 1 of the inner stopper and the inner stopper lid, the valve holder 3 can be taken out and washed. Further, by forming the introduction port 5 for the pressurized air and the air passage to be communicated to the introduction port 5 and the inside of the inner container in a size capable of supplying the content liquid, the content liquid can be supplied into the inner vessel without removing the inner stopper.
