ABSTRACT:
An improved composite closure is described which includes a cover portion and a molded plastic ring portion. The plastic ring portion is molded by a new method with top tool core removal which permits formation of inwardly directed tabs or fishhooks on the tamper evident ring. The molded ring also permits the cover to be inserted from the top of the ring rather than upwardly over the ring threads, which is an easier and faster method of assembling a composite closure.
