Abstract
Abstract This disclosure is directed to a latch mechanism carried by a peripheral skirt of a container closure, the latch mechanism including a pair of spaced supporting straps of flexible material joined together by a bridging member, a latching hook disposed between the supporting straps and being carried by the bridging member, and the latching hook having a latching nose projecting toward the peripheral skirt whereby in the latched condition of the latch mechanism the latching nose is adapted for latching engagement against a container latching surface and is held thereat by the flexible nature of the and/or straps ad/or a resilient gasket (compressed). Preferably the latch mechanism also includes an upright projection carried by the bridging member outboard of the latching nose and between the supportng straps against which pressure is applied to pivot the latching hook through the bridging member incident to latching and unlatching operations.
