Abstract
A novel structure of pressure container is disclosed, wherein a safety valve is provided within an air injection valve of said pressure container, whereby even when the ambient atmosphere of said accumulator has been heated up to a high temperature because of a fire and the like, bursting of said pressure container may be prevented. A valve seat is formed inside of a valve casing and a fusible valve member is brought in contact with said valve seat, so that when the ambient temperature of said pressure container has been raised said fusible valve member may fuse to permit the gas pressure in the pressure container to be discharged to the exterior of the container. Said fusible valve member is filled within a hollow space of a cylindrical valve stem and said valve stem is provided with a passageway or passageways communicating with the interior and exterior thereof, so that when the fusible valve has been fused, the gas within the gas pressure container may blow away the fusible member in a fused state through said passageway or passageways to the exterior of the container.
