Abstract

A member is provided for being mounted on the neck of a container. The member has a skirt with at least a first annular section extending axially below an annular bead on the container. A plurality of circumferentially spaced arms are flexibly connected to, and extend from, the skirt first annular section at a first bend line to accommodate radially inward pivoting of each arm to an orientation generally alongside the skirt first annular section. A plurality of circumferentially spaced tabs are each flexibly connected to, and extend radially inwardly of, one of the arms at a second bend line to accommodate radially inward pivoting of each tab toward the container when sufficient relative axial displacement is effected between the closure and the container. A novel method is provided for arranging unique mold parts for molding the mounting member and for moving the mold parts to release the molded mounting member in an assembly-ready orientation for application to the container.
