<p>A tamper-indicating plastic closure (10) includes a plastic closure cap (12) having a top wall portion (14), and a depending cylindrical skirt portion (16), and an annular pilfer band (24) depending from the skirt portion (16). The pilfer band (24) includes a plurality of circumferentially spaced flexible tabs (32), and an annular interference bead (34), with the arrangement configured to provide two modes of tamper-indicating interfraction with an associated container. In order to facilitate high-speed application of the closure (10) to a container, each of the flexible tabs (32) includes a relatively thick central portion (38), operative during the second mode of tamper-indication, and an adjacent base portion of relatively reduced thickness for enhanced flexibility. <IMAGE></p> |
