摘要

A method for molding and sterilizing a container made of a plastic material, comprising the steps of: opening a mold (4) made of a metal material, inserting a parison (3) into the mold (4), closing the mold (4) Inserting the stretching rod (23) into the parison (3), blowing gas into the parison (3) to stretch it into a container, fastening the stretching rod (23) inside the molded container, evacuating the blowing fluid , Applying a voltage difference between the stretching rod (23) and the closed mold (4) so as to change the atmospheric pressure fluid remaining inside the molded container to plasma.
