摘要: An improved molded closure cap is described which has a softer sealing portion and relatively hard engaging portion. The using two differing plastics where the container of seal-forming plastic remaining or shell harder plastic. novel molding apparatus method employ plunger die movement to facilitate successive soft portions without changing die.
