摘要： In a machine for the manufacture, filling and closure of plastic containers, undesired residue of the filling material is removed from a filling mandrel which extends into the container to be manufactured by provision of a constriction in the blow molding equipment within which the container is formed. The filling mandrel comprises an enlarged end upon which undesired residue tends to accumulate. The blow mold is formed with a constriction through which the mandrel is withdrawn and by forming a gap between the mandrel and the constriction, which gap is approximately equivalent to the thickness of the container, unwanted residue is automatically stripped from the mandrel as it is withdrawn.

摘要： Successive increments of a thermoplastic tube are extruded in vertical direction from an orifice, and a first partible mold is closed about the increment immediately downstream of the orifice whereupon the increment is expanded to the shape of a first semi-finished container, while simultaneously completing the expansion of the neck region of an already filled second semi-finished container accommodated in a second partible mold downstream of the first mold and communicating with the interior of the first container, is completed. The containers are then sealed and separated from one another and the first container in the first mold is filled. The second container is discharged from the second mold and the relative positions of the molds are reversed in preparation for repetition of the preceding steps.

摘要： In a molding process wherein a pair of mold halves pivoted on respective axes flanking a mold-closing plane are closed together scissor-fashion on an extrusion issuing continuously down in the vertical mold-closing plane, each of the mold halves is displaced during closing of the mold halves away from its respective pivot axis. Such displacement away from the axis is effected by means of a cam arrangement during the last stages of closing in order to insure that the mold cavities remain perfectly aligned with the extrusions being closed in them.
