PROBLEM TO BE SOLVED: To achieve simplification of process, reduction of installation area of equipment, equipment cost, and operation and maintenance cost by a method wherein both of the molding and the sterilizing of a plastic container are performed simultaneously without using a cleaning liquid to sterilize the molded plastic container. SOLUTION: A preformed material 4 having a test tube-like shape is set in a blow molding die 15, and the preformed material 4 is stretched by means of a stretching rod 5, following which an ozone gas 24 is blown into the stretched preformed material 4 to inflate it. Thus, a plastic container having an external shape made after the internal surface of the die 15 is molded and at the same time, the internal surface of the plastic container is sterilized. |
