Zusammenfassung:A method for producing a plastic container by internal pressure forming including arranging a hose-shaped preform between the molding dies of a mold, formed having a mold cavity; closing the mold and forming or preforming a container from the preform by internal pressure, wherein a circumferential section of the preform is pressed through a mold gap into a chamber surrounding the mold cavity and is pressed in the chamber against claw pairs having stationary inner retaining claws and movable outer tear-away claws; and laterally moving the outer tear-away claws, causing the circumferential section between the outer tear-away claws and the inner retaining claws to be torn open and the container to be split into two container halves. Also disclosed is a mold suitable for performing the method.
