Abstract: A blow molded hollow plastic article having openings at both ends. One of those openings is a main opening and a secondary opening defined by an angled passageway is provided adjacent the main opening. The article is blow molded in a single operation by a method which includes the step of laterally stretching a tubular parison from which the article is to be molded so as to receive a primary mandrel for forming said opening and a secondary mandrel for forming the passageway. Air is introduced into the parison through the secondary mandrel to form the inner end portion of the passageway while the parison is expanded to conform to the shape of the mold.

Abstract: The disclosure relates to a method and apparatus for blow moulding hollow plastic articles each having at an end thereof, a main opening and a secondary opening defined by an angled passageway. The method includes the step of laterally stretching a tubular parison from which the article is to be moulded so as to receive a primary mandrel for forming said opening and a secondary mandrel for forming the passageway. Air is introduced into the parison through the secondary mandrel to form the inner end portion of the passageway while the parison is expanded to conform to the shape of the mould.

Abstract: The disclosure relates to a method and apparatus for moulding hollow plastic articles each having a relatively wide neck portion. The method includes the step of mechanically expanding an end portion of a tubular parison from which the article is to be moulded, and introducing into the expanded end portion of the parison a mandrel which cooperates with the mould to form the neck of the article. Subsequently, the parison is expanded by internal air pressure to form the remainder of the article. Movable mould inserts for relieving pressure around the neck of the article are also disclosed.
