DISPENSING CLOSURE, PACKAGE AND METHOD OF MANUFACTURE

摘要

A closure includes a shell (28 or 92) of relatively rigid plastic material having a deck (38) and a peripheral skirt (46), at least one recessed shoulder (60 or 62) in the deck adjacent to the skirt, and a plurality of angularly spaced external channels (64) extending along the skirt from the recess. An external feature (74 or 76 and 80 or 94) of flexible resilient second plastic material different from the first plastic material is integrally molded onto the shell within the recessed shoulder and the channels. By way of example only, the shell may be of polypropylene material and the external feature may be of thermoplastic elastomer material. Lock elements, such as openings (66) in the deck recessed shoulder and/or pegs (68) in the skirt channels, cooperate with the external feature molded onto the shell to retain the external feature on the shell.
