Abstract
A cap for venting a tank containing a fluid which expands in response to heat applied externally to the tank and which cap includes an outer annular nut, an inner circular central disc, and an intermediate annular ring of polymer-based material which softens in response to the externally applied heat to permit the inner circular central disc to be blown out of the outer annular nut thereby venting the tank and preventing the tank from exploding.
