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.
Claims8
A cap for venting a tank containing a fluid which can expand to the point of exploding the tank upon sufficient external heat being applied to the tank, comprising:
- an outer metal member for being connected to the tank;
- an inner metal member;
- and
- an intermediate member intermediate and for interconnecting the outer metal member and the inner metal member, said intermediate member made of a yieldable polymer-based material and for yielding in response to external heat applied to the tank to permit said inner metal member to be blown out of said outer metal member to vent the tank to the atmosphere prior to the tank exploding.
