Beschreibung
Zusammenfassung:	A grip cap for a container has a thermoplastic shell in an inverted cup shape with a top wall and a skirt bounded by a lower rim. An elastomeric layer is integrally molded to the cap shell along the outer surface of the top wall and the skirt as well as along the underside of the lower rim. This layer defines multiple spaced apart and raised vertical ribs joined by a pad at the top wall and a gasket extending along the lower rim. The ribs and the pad provide a cushion and the gasket can seal against a shoulder of the container when tightened. Also disclosed is a two-shot method of molding such a grip cap, including integral resilient material at the outer surfaces and the underside of the cap shell rim.
