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 defined by a pair of vertically spaced, vertical scores. In order to substantially prevent any propagation of the upper one of the vertical scores, another score is formed in intersecting relation thereto. Consistent manufacture and reliable performance are further promoted by the formation of a stabilizing score in operative association with the fracturable portion of the pilfer band.
