Patent number: 8574486Abstract: 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).Type: GrantFiled: August 30, 2004Date of Patent: November 5, 2013Assignee: KHS Corpoplast GmbHInventors: Wolf Jaksztat, Michael Linke, Rolf Baumgarte, Michael Litzenberg, Klaus Vogel, Günther Godau

Patent number: 8535037Abstract: A blow molding machine for producing plastic bottles, particularly PET bottles, including a plurality of blow molding stations, which have assigned thereto valve blocks with control valves and blowing nozzles for introducing or discharging blowing air; and a cleaning-in-place (CIP) system for cleaning the blow molding machine. Since the valve blocks are configured such that they can be included in the CIP process, the system components, such as the blowing nozzle, which are particularly important for the production of PET bottles in terms of hygiene, can be cleaned and sterilized without disassembly.Type: GrantFiled: May 27, 2010Date of Patent: September 17, 2013Assignee: Krones AGInventor: Klaus Voth

Patent number: 8496467Abstract: 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.Type: GrantFiled: September 3, 2010Date of Patent: July 30, 2013Assignee: Soplar SAInventors: Markus Dueringer, Martin Hammerle
