PURPOSE: A gas container for safety is provided to be safely used after exhausted by mounting an attachment plate on a surface for easily drilling a hole. CONSTITUTION: A cutting piece(21) is lifted by an outward bent portion(22) through a space(25) of an attachment plate(20) and a drilling pin(23) is bent inward by an inward bent portion(24). In this state, the pin is pushed in a moment to drill a hole on the surface of a gas container(10). Therefore, residual gas inside the gas container is safely discharged outside and is prevented an explosion.
