Abstract

A method for the production of blow-molded containers that are sterile at least in certain regions, and a blow-molding machine configured to carry out the method. In accordance with the method, blowing stations are arranged on a rotating blowing wheel. A preform of a thermoplastic material is first heated and then stretched in a blowing station by a stretching rod and subjected to a pressurized blowing fluid via a blowing nozzle. A sterilizing fluid is supplied to the preform in the blowing station to perform a sterilization. The sterilizing fluid is fed into the preform from an outlet and is carried away again via an inlet and in between follows a flow path. The sterilizing fluid is made to pass through or pass by the stretching rod on its flow path, and the sterilizing fluid is supplied while the blow-molding machine continues to operate.
