Abstract
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 The blow mold is formed with a constriction through which the mandrel is withdrawn and by forming a gap between the mandrel and the constriction, which gap is approximately equivalent to the thickness of the container, unwanted residue is automatically stripped from the mandrel as it is withdrawn.
