Abstract

A container closer (10) particularly for use on screw top containers such as carbonated beverage containers, the container closure (10) having a generally cylindrical continuous tamper evident band (11) joined by a plurality of frangible bridges (13) to the free edge of a skirt (16) of the closure (10). The band (11) has a segmented internal rib (18) which engages an external retaining flange of the container when the closure (10) is applied to the container so that on removal of the closure (10) the tamper evident band (11) remains on the container or is visually clearly damaged by removal of the closure (10) from the container. The band (11) is provided with longitudinal reinforcement by projections (25 and 28) or other areas of thickening (26) to provide the band (11) with longitudinal stiffness while still permitting it to expand over the retaining flange on the container. The rib (18) has a first annular side (21), the first annular side (21) having a compound surface comprising a radially outer frusto-conical portion (23) which assists in the molding of the rib (18) and a radially inner substantially planar portion (24) which increases the difficulty of removing the closure (10) intact from the container without rupturing the bridges joining the tamper evident band (11) from the remainder of the closure (10).
