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.

A fluid pressure container provided with an injection valve and valve seat for communicating the exterior of said container with the interior of it, characterized by the provision of relief of internal pressure upon ambient temperature rise including: a. a hollow valve stem slidably disposed within said injection valve and having at least one passageway extended therethrough, said passageway providing the only path for escape of fluid from within the container to the exterior of the container, and b. a fusible valve member filling said hollow valve stem and having a portion of the fusible member in contact with the valve seat of said injection valve providing the sole valve closing function by such contact with the valve seat to retain pressurized fluid in the container, said fusible valve member closing said passageway in said valve stem by said filling the hollow thereof, the injection valve having a fluid passage beyond said seat to the exterior of said container for flow of said fusible valve member under conditions of elevated ambient temperature to open both the passage through the hollow valve stem and said injection valve by removal of the fusible material to the exterior of the container.
