Abstract: Disclosed are a method and a device for blow molding containers (2). A parison (1) is stretched by means of a stretching rod (11) within a blow mold (4) and molded into the container by applying blow pressure following thermal conditioning. The pressurized gas is introduced into the container (2) via at least two different flow paths (55, 56). Advantageously, one of the flow paths (56) ends near the orifice area (21) while a second flow path (55) ends near a container bottom (51). At least some of the pressurized gas is introduced into the container (2) through the stretching rod (11).

Abstract: Disclosed are a method and a device for blow forming containers (2). A parison (1) is stretched by means of a stretching rod (11) within a blow mold and molded into the container (2) by applying blow pressure following thermal conditioning. Pressurized gas is introduced into the container (2) through the stretching rod (11). The pressurized gas is laterally introduced from a pressure chamber into an interior space of the stretching rod (11). The stretching rod comprises at least one passage opening (53) between a tip (51) facing the blow mold and an end (52) of the stretching rod, which faces away from the blow mold. Said passage opening (53) extends into the interior space of the rod so as to deliver the pressurized gas.

Abstract: The invention relates to a method and to a device which is used to blow-form containers (2). A preform (1) is stretched inside a blow form (4) by a horizontal bar (11) after thermal conditioning and is shaped in the container by means of blow pressure effects. At least one part of the pressurised gas is guided towards the base area of the container (2). One particular advantage of said invention is that the flow path ends in the vicinity of the base area. At least one part of the pressurised gas (2) is guided into the container by the horizontal bar (11).

Abstract: The method serves for tempering preforms made of a thermoplastic material. The preforms are provided for blow deformation into containers. The preform is provided with a temperature profile along the periphery. The temperature profile is produced in that striplike regions extending in the direction of the longitudinal axis of the preform are heated differentially. Stepwise tempering is carried out for successively timed thermal conditioning of various regions of the preform.
