ABSTRACT:
Apparatus for venting a pressurized gas container is disclosed. The container bottom moves outward as a result of over-pressure caused by excessive temperature. The bottom pushes against a member of the housing, thereby forcing the nozzle head to hit and become fixed against a second member of the housing. Continued movement of the container body toward the nozzle head effectively depresses the nozzle head, thus releasing gas from the container. In a preferred embodiment, a safety plug in a passageway in the nozzle head is melted to provide a channel for the vented gas.
