APPARATUS FOR BLOW MOLDING HOLLOW PLASTIC BODIES

摘要

An electrically heated sterilization chamber for a hollow blow molding needle is embodied in a half-mold 1A and exits directly into the mold cavity . A threeway distributor core enables the selective connection of the sterilization chamber to the mold cavity or to a circuit comprising a vacuum source and a source of sterile water vapor coupled in parallel. The needle is initially sterilized by the hot water vapor, and thereafter maintained in a sterile state by the electrical heating and its confinement within the half-mold.
