Abstract
A tamper-indicating plastic closure includes an annular pilfer band which is partially detachably connected to a skirt portion of the closure, whereby the pilfer band remains connected to the closure after closure removal from an associated container. The pilfer band includes at least one fracturable region which fractures during closure removal, whereby the pilfer band splits and separates into a plurality of segments. Each segment is preferably dimensioned to facilitate its removal from an associated container by automatic washing equipment in the event that one of the segments is inserted into the container by a consumer.
