Abstract
A method and a device for producing blow-molded containers, which are sterile at least in some areas, in a blow-molding machine. A preform made of a thermoplastic material is first heated, then stretched by a stretching rod in a blowing station, and then supplied with a pressurized fluid via a blow nozzle, wherein a sterilization device is arranged in the blowing station. The sterilization device has at least one radiation source which emits a sterilizing radiation onto the stretching rod and/or onto the blow nozzle.

A method for manufacturing blow-molded containers which are sterile at least in some areas in a blow-molding machine, the method comprising the steps of:
- initially heating a preform made of a thermoplastic material;
- stretching the preform with a stretching rod in a blowing station and, by way of a blowing nozzle, impinging the preform with a pressurized fluid;
- and emitting a sterilizing radiation onto the stretching rod and/or onto the blowing nozzle from at least one radiation source of a sterilization installation disposed in the blowing station.
A device for manufacturing blow-molded containers which are sterile in at least some areas, that device comprising:
- a heating section for temperature controlling preforms of a thermoplastic material;
- at least one blowing station for blow-molding the preforms to form containers, wherein the blowing station has a stretching rod for stretching the preform and a blowing nozzle for impinging the preform with a pressurized fluid;
- and a sterilization installation disposed in the blowing station, wherein the sterilization installation has at least one radiation source that emits a sterilizing radiation onto the stretching rod and/or onto the blowing nozzle.
