Abstract

A tamper-indicating plastic closure includes a pilfer band at least partially detachably connected to a skirt portion of the closure by a frangible connection. The frangible connection comprises a plurality of circumferentially spaced frangible bridges, which fracture attendant to removal of the closure from an associated container to provide visually discernable evidence of opening. In order to facilitate high-speed application of the closure to a container, one or more regions of the frangible connection are preferentially strengthened by the provision of relatively strengthened frangible bridges. At least one of the strengthened bridges is generally diametrically opposed to the leading portion of the internal thread formation of the closure.
