Abstract

An apparatus for shaping plastics material pre-forms to form plastics material containers may include a conveying device which conveys the containers along a pre-set conveying path, a stressing device which acts upon the containers with a flowable medium in order to expand them, a reservoir for storing the flowable medium, and a supply device which delivers the flowable medium from the reservoir to the container. A valve device controls the supply of the flowable medium into the containers, in order to expand the containers. The apparatus includes a first feed line in order to supply a flowable sterilization medium to the supply line between the reservoir and the container to be treated or in a removal line for the flowable medium, which removes the flowable medium from the containers.
