Abstract

PROBLEM TO BE SOLVED: To enable pressurized gas to be injected by an injector and also to enable contents in a container to be removed by fitting and pressing a flow-out member with an O-ring instead of the injector to an upper end slope of a valve lever. SOLUTION: At the time of removal, a flow-out member with an O-ring is fitted to an upper end slope of a valve lever instead of an injector and is pressed against elastic force of a coil spring and lowered, whereby a stem rubber 7 opens a lateral hole 8 and a slit 16 similarly to the time of injection. Pressurized gas in a container 1 rises from a lateral hole 15 of a valve housing 3 through a slit 16, flows through a through hole 21 to a longitudinal flow path 14, while it passes through a slit between a large diameter lower end 10 of the valve lever and an internal face of a stem rubber receiving seat ring 18, rises in a longitudinal hole 11 through the lateral hole 8, and combines with a flow which has flowed through the through hole 21 into the longitudinal flow path 14 for flowing out.
