METHOD AND DEVICE FOR BLOW-MOLDING CONTAINERS

摘要

The method and the device are used for blow-molding containers (2). To this end, following thermal conditioning inside a blow-molding tool (4), a preform (1) is shaped into the container (2) under the action of blowing pressure. The necessary blow-molding gas is introduced into an interior space of the preform (1) through a connecting element (42). The connecting element (42) is pressurized in the direction of a preform longitudinal axis (45) by a contact pressure device (51) in order to seal it relative to the preform (1). Pressure forces acting on the connecting element (42) are absorbed by a mechanical retainer (52) of the contact pressure device (51). The connecting element (42) is detachably fixed by the retainer (52).
