Document Type and Number:
WIPO Patent Application WO/2014/202224
Kind Code:
A8
Abstract:
The invention relates to a method for producing containers filled with a liquid filling material (8) from blanks (1) made of a thermoplastic material and to a nozzle (10) for use in such a method. The problem addressed by the invention is that of presenting a method for monitored or controlled shaping of a blank (1) to form a container, wherein contamination of the exterior of the container or of the filling machine caused by filling material splashed by the stretch rod is prevented. To solve the problem, a method for producing containers filled with a liquid filling material from blanks (1) made of a thermoplastic material is provided, wherein each blank (1) is at least thermally conditioned and is then shaped to form the container in a mould during a shaping phase, by means of axial and radial stretching, as a result of liquid filling material (8) being introduced under pressure into the blank (1) through a nozzle (10). The method is characterized in that the axial stretching is initiated by the pulsed injection of filling material (8) into the blank (1).
