Abstract
A device for molding plastic blanks to give plastic containers with a blow mold may include a cavity within which a plastic blank may be molded to give a plastic container. The blow mold has a base part to form a base section of the container. The base part defines the cavity. The device may include a filling device for introducing a gaseous medium into the plastic blank via the mouth thereof, in order to expand the plastic blank within the blow mold, with a rod-like body, which may be moved relative to the blow mold in order to draw the plastic blank during the molding process. The base part has a forming section defining the cavity, for forming the base section of the container which matches the shape of the base section of the container, and the forming section has a projection running in the direction of the cavity in a central region.
