Abstract
A tamper-indicating plastic closure construction is disclosed which includes an annular pilfer band which depends from an annular skirt portion of the closure. The pilfer band is partially detachably connected to the skirt portion by frangible ribs, and remains connected to the skirt portion attendant to removal of the closure from a container. To facilitate such removal, the pilfer band includes a fracturable portion. Consistent and reliable performance are promoted by the formation of a stabilizing score in operative association with the fracturable portion of the pilfer band. A method of forming the closure is also disclosed, including the provision of movable scoring blades for effecting scoring of the closure to facilitate high-speed manufacture.
