METHOD FOR PRODUCING CONTAINERS FILLED WITH A LIQUID FILLING MATERIAL FROM BLANKS MADE OF A THERMOPLASTIC MATERIAL AND NOZZLE FOR USE IN SUCH A METHOD

摘要

A method for producing containers filled with a liquid filling material from blanks made of a thermoplastic material and to a nozzle for use in the method. In the method, each blank is at least thermally conditioned and is then shaped to form the container in a mold during a shaping phase, by axial and radial stretching, as a result of liquid filling material being introduced under pressure into the blank through a nozzle. The axial stretching is initiated by the pulsed injection of filling material into the blank.
