2112815 9404428 PCTABS00030 A linerless plastic closure (10) is configured for side-sealing engagement with an associated container (C). The closure includes a circular top wall portion (12), and an annular skirt portion (14) depending from the top wall portion, and including an internal thread formation (16). A two-component side-seal arrangement is provided which includes a relatively rigid support annulus (32), and a relatively flexible sealing lip (30). The sealing lip (30) is movable into a position for sealingly engaging a generally outwardly facing surface of an associated container (C), with the relatively rigid support annulus (32) desirably acting to enhance the sealing effect of the sealing lip (30). Notably, the relatively rigid sealing annulus (32) further desirably acts to provide a self-centering action for the closure (10) during application to a container.
