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.

Disclosed is a method for forming blanks made from plastic material into containers, the method including steps of blowing into the blanks in such a way as to form them into containers, then internally degassing the formed containers. In the method, the steps are carried out according to a first cycle at a first rate. Then, during a second subsequent cycle of steps carried out at a second rate slower than the first rate, a time delay is added with respect to the first cycle, during or after degassing, such that the second cycle lasts longer than the first.
