Abstract
An electrically heated sterilization chamber 9 for a hollow blow molding needle 15 is embodied in a half-mold 1A and exits directly into the mold cavity 3, 4. A three-way distributor core 11 enables the selective connection of the sterilization chamber to the mold cavity or to a circuit 21 comprising a vacuum source 35 and a source of sterile water vapor 37 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.
