ABSTRACT:
Frangible areas of different configuration are formed between cap and skirt portions of different embodiments of molded plastic closures. Such frangible areas formed from within the closure by throughcuts, undercuts, and grooves are facilitated by also forming the skirt to extend from and diverge out from the cap to facilitate ejection of the closure from its mold; and by forming one or more surfaces on the skirt to also facilitate ejection of the closure from its mold.
