  • Patent number: 8574486
    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).

  • Patent number: 8550805
    Abstract: A process and a device for the manufacture of a hollow body, particularly of a heat-resistant hollow body, which is molded out of a heated preform of thermoplastic plastic in a contoured blow mold through the introduction of a first medium into the preform, which medium is stored in a first medium storage unit and is under a pressure (p1) (preblowing phase), and the more or less simultaneous stretching of the hollow body through a stretching rod and the introduction of a second medium in the hollow body, which medium is stored in a second medium storage unit and the pressure of which (p2) is higher than the pressure of the first medium (p1) (final blowing phase), and which is cooled by a third medium, which is medium stored in a third medium storage unit (rinsing phase), whereby the preblowing medium is under a pressure of approximately 2-20 bar, the final blowing medium is under a pressure of approximately 15-45 bar, and the cooling medium is under a pressure of approximately 30-45 bar.

    Abstract: A device and method are disclosed for the production of hollow bodies, especially plastic bottles, wherein a section of a plastic flexible hose is placed in a cavity of a blow mold by an extruder head according to a predefined clocked pulse. The plastic flexible hose is inflated inside the blow mold by a blow mandrel by overpressure according to the blow mold cavity. The manufactured inflated hollow body is subsequently removed from the mold. The plastic hose can be continually held on opposite sides of the blow mold arrangement during the entire extrusion and blow cycle.

    Abstract: A system for forming a container from a preform, wherein the preform has a finish and a support ring. The system includes a mold having a mold cavity defining an internal surface and adapted to accept the preform, a pressure system having an inlet and an outlet outputting fluid, a blow nozzle receiving the fluid from the pressure system and introducing the fluid at a pressure into the preform thereby expanding the preform toward the internal surface of the mold cavity and creating a resultant container. The system further includes a first seal engagement selectively engageable between the blow nozzle and the finish of the preform and a second seal engagement selectively engageable between the blow nozzle and an adjacent feature.
