Patent ID: 7192548

Claim:
A method for the manufacture of a tube having a distribution spout surmounting a neck that radially tapers to a flexible tubular skirt, comprising a molding phase and a mold removal phase, the molding phase, including forming the tube by injecting a molten thermoplastic injection material through a central injection channel into a molding cavity having a mold joint at least partially delimited by a core and an impression, the spout being molded in a part of the molding cavity adjacent to an injection passage; and the mold removal phase, following the molding phase after solidification of the injection material, comprising a holding operation including temporarily holding the tube by the spout by means of slides placed beforehand in a mutually closed position before the molding operation, and wherein the holding operation continues during the opening operation; a mold release operation including partially extracting the core from the tube; an opening operation including opening the molding cavity, and an ejection operation including ejecting the tube from the molding cavity and interrupting the holding operation by separating the slides from each other, and blowing air between the separated slides and an external surface of the spout, the opening operation being consecutive to the mold release operation and including opening the molding cavity at the mold joint between the neck and the skirt of the tube, further comprising an accompanying operation concomitant with at least one of the operations of mold release and of opening, and which includes blowing air between the core and the tube to detach the tube from the core.
