ABSTRACT:
A locking gas cap for a threaded filler neck having a sealing lip extending peripherally about its axis, the cap comprising a closure member threaded to engage and close the filler neck, a gasket on the closure member for engaging and sealing against the lip, an outer shell providing a hand grip secured to the closure member for rotation thereon, a key-operated lock and at least one locking member movable by the lock connected to the shell for rotation therewith. A race is disposed for rotation in the shell, and a driving connection is provided between the race and the closure member which is torque limited in the direction which advances the closure member on the filler neck and positive in the opposite direction, the locking member being movable into and out of engagement with the race selectively to provide a driving connection between the shell and the race. The preferred embodiment includes a frictional driving connection between the race and the shell in the direction which advances the closure member on the filler neck even when the locking member is out of engagement with the race.
