Abstract

Disclosed are a method and an apparatus (2) for blow-molding receptacles (2). In said method and device, parisons (1) made of a thermoplastic material are heated in the area of a heating section and are then transferred to a blowing device (3). The parisons are molded into the receptacles under the effect of a blowing pressure inside blow molds (4) in the area of the blowing device. A sealing element (49) which is guided towards a supporting ring (52) of the parison is disposed in the area of the blowing device. The sealing element is first prestressed in a mechanical fashion relative to the supporting ring after entering in contact with the supporting ring and is then further stressed in a pneumatic fashion, thus creating a receiving space (47) which encloses the mouth section (21) of the parison and has essentially the same pressure as the interior of the parison in order to prevent the mouth section from being deformed.
