Remain gas exclusion structure for gas vessel

摘要

PURPOSE: A structure of eliminating remained gas in a gas container is provided to easily eliminate remained gas and to prevent accident by not generating spark. CONSTITUTION: To waste a gas container(10), a handle(13a) of a lever(13) is lifted. The lever operates a leverage of an extended unit(13b) centering upon a rivet(14). Thus, the rivet is replaced. Herein, inner head of the rivet is formed in a small sphere shape for being easily removed from a main wall(11). Thus, a discharge aperture is formed at the place for the rivet. Remained gas in the gas container is discharged through the discharge aperture.
