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