  • Valves for pressurized containers
    Patent number: 5794660
    Abstract: A non-refillable valve for a pressurized container which includes a unidirectional stepped valve housing within which a freestanding blocking element is housed. The blocking element is preferably a reversible, symmetrical check that integrally includes stop means for preventing the return of said blocking element to an initial location after it has been moved to a final location that activates the one way characteristic feature of a non-refillable valve (where activation is designed to take place after initially charging of the container). Further aspects of the invention relate to blocking elements (checks) per se which are suitable for use in non-refillable valves.
