Abstract
A compression molding machine, for compression molding a closure shell having a base wall with an opening and in accordance with one aspect of the disclosure, includes a male mold section and a female mold section having associated surfaces that oppose each other to form a cavity for compression molding the base wall of the closure shell. An annular bead on one of these surfaces cooperates with the opposing other surface to compression mold a disk connected to the base wall by a thin frangible web. The disk and the shell are stripped separately from the mold so that the shell emerges from the machine with the opening formed in the shell base wall by removal of the disk within the machine.
