Abstract
A tamper-evident closure assembly ( ) for a valve outlet ( ) of a pressurized gas cylinder, or the like includes a cap ( ) and a tamper-evident ring ( ). The assembly is threadably attached to the outlet prior to shipment and removed by a customer prior to dispensing fluid through the outlet. The ring includes tabs ( ) which snap fit into slots ( ) in the cap and cause the ring to rotate with the cap. Fins ( ) on the ring engage a surface of the valve outlet during cap removal. When sufficient force is applied in the cap removal direction, part of the ring is severed, such as the tabs or the fins. This provide evidence that the cap has been removed.
