20140314984 | METHOD FOR PRODUCING A PLASTIC BOTTLE, AND PREFORM AND BLOWING MOLD SUITED THEREFOR - Method for producing a plastic bottle, and preform and blowing mold suited therefore are disclosed. An exemplary process can produce a plastic bottle, for example, a PET bottle. Such a bottle can be produced from a preform which has a body which is closed on one side, which is connected to a neck section with a pour opening, in which the preform which has been produced in a plastic injection process or an extrusion process is placed in the mold cavity of a blow mold and inflated using the blow nozzle by overpressure according to the mold cavity. Sealing can take place between the blow nozzle and the preform within the preform. | 10-23-2014 |
20140069943 | METHOD FOR CALIBRATION OF A POUR OPENING OF A PLASTIC CONTAINER PRODUCED IN AN EXTRUSION-BLOW-MOLDING METHOD - A method is disclosed for providing dimensional accuracy of a pour opening in or on a plastic container produced by extrusion-blow-molding. The method can include inserting a section of a plastic hose, extruded in one or more layers through an extrusion nozzle, into a mold cavity of a blow mold tool; and inflating the plastic hose by a calibrating blow pin according to a shape of the mold cavity, whereby at least one pour opening of the plastic container is determined with respect to its inside diameter and its inside contour to form a completed inflated plastic container, and wherein the calibrating blow pin is axially inserted into the plastic hose section after a head plate of the blow mold tool has been closed. | 03-13-2014 |
