    摘要: A plastic tamper evident cap (10) includes a skirt (14) having threads (16) for engaging threads on a neck of a container for closing and opening the container, and an annular frangible band (20) connected to and depending from the skirt (14), wherein the band (20) includes an outer wall (22) frangible connected to the skirt (14) by a line of weakness comprising fracturable bridges (18), and an inner wall (24) joined to the bottom of the outer wall by a curvilinear connecting portion (21) and extending therefrom inwardly and upwardly in a generally inverted ''J'', ''U'', ''V'', ''triangulated curl'' or ''trapezoidal'' cross-sectional shape, wherein the inner wall (24) includes a free end (30) comprising a rim (26) adapted to engage the interfering means on a container. The rim (26) of the inner wall also can include a sharply curvilinear configuration which provides a compressible and resilient interfering surface that nests tightly against the underside portion of a projecting bead or shoulder on the container neck to thereby provide significant interference upon initial removal of the cap (10).
