Abstract (en)
A tamper-evident, container closure cap (10), features a resiliently-deformable, inward retention lip (18), for co-operative interaction with an upstanding retention rim (32) upon a container neck (31); the lip being integrally moulded with a circumferential cap wall and reverse-fold, in-turned or inverted to create a resilient inward lip; a frangible inter-connection between lip and cap body utilises weakening, through localised reduction in wall thickness, leaving residual tabs (21). Cap removal requires severance of a lower depending, peripheral tamper strip (15), carrying the resilient inward retention lip, from the upper body (12) of the cap. <IMAGE>
