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.
Claims12
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 a blowing station of the at least one blowing station has a stretching rod for stretching a preform of the preforms 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, wherein the at least one radiation source is arranged outside of a blow mold and is disposed so as to be positionally fixed in relation to the blowing station such that the at least one radiation source emits radiation onto a side of the blowing nozzle that faces the preform and/or onto a mouth area of the preform.
