A plastic closure for a container.

摘要

A novel plastic closure (10) is disclosed having a self-engaging locking pilfer band arrangement for engagement with a locking ring (26) on the neck (24) of the container (12) to which the closure (10) is applied. The pilfer band (34) includes a plurality of circumferentially spaced, inwardly extending relatively thin flexible wings or fingers (42) which move to an out-of-the-way position during application of the closure (10) to the container (12). When the closure (10) is in place on the container (12), the wings (42) are disposed such that they engage the surface of the locking ring (26) on the container neck (24) when the closure (10) is moved for removal from the container (12). During removal, each wing (42) engages the locking ring (26) so that resistance to removal of the closure (10) is created in the pilfer band (34), whereby areas of reduced strength fracture clearly indicating partial or complete removal of the closure (10) from the container (12).
