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.
