<p>A tamper-indicating plastic closure (10) is disclosed, with the closure configured for interfering coaction with an associated container. The closure includes a plastic cap (12) having a top wall portion (14) and an internally threaded annular skirt portion (16), with an annular pilfer band (20) depending therefrom. The pilfer band (20) includes a plurality of circumferentially spaced flexible tabs (28) for interfering engagement with an annular locking ring portion (L) of the associated container. The pilfer band (20) further includes an annular interference bead (30) positioned beneath the flexible tabs (28). By this arrangement, two modes L(Figs, 4 and 5, respectively), of interfering engagement with the associated container locking ring (L) are provided. In an alternate embodiment, the pilfer band includes an angularly skewed interference lip and centering ribs.</p> |
