ORIGIN-PROOF CLOSURE FOR GAS BOTTLE VALVES

摘要

In some fields of application, the need exists to equip gas bottles with an origin-proof closure so that interference with the contents of the bottle can be detected. This purpose is served by a strap which surrounds the valve body at the level of the gas-bottle valve connector nozzle (3). The strap possesses a cap-shaped projection (8) which encompasses the gas-bottle valve connector nozzle (3) and a closure for undetachably connecting the closure ends to each other. The origin-proof closure is preferably designed as an integral plastic moulding.
