Abstract
Abstract A safety closure for a container having an outwardly extending annular lip, said closure comprising a cap having an inwardly extending fixed lug which engages the underside of the lip and an opposite hinged lug which normally engages the underside of the lip but which can be pulled outwardly to disengage the lug permitting removal of the cap. The under surfaces of the two lugs may be tapered so that the cap can merely be pushed in place over the lip.
