Abstract
This relates to closure assemblies for containers which are subject to tampering. This particularly relates to closure assemblies of the type which include a lever type actuator wherein the lever must be lifted to apply leverage to a closure plug portion to facilitate opening of the closure assembly. Such levers are customarily retained in place by rivets which include frangible portions. This particularly relates to the configuration of such rivets and the details of the lever wherein, once the lever has been pried from its original position and disengaged from the rivet, the lever or an end portion only thereof tilts upwardly due to the non-returnability of the rivet through its original opening thereby to present a visual indication of tampering which can be readily ascertained.
