  • Patent number: 4195053
    Abstract: A method and apparatus are disclosed for blow molding a container with an angular neck from a parison of thermoplastic material at a single station at which extrusion of the parison, compression molding of the neck of the container and blowing of the parison occurs. In the method, the mold sections, which have a cavity that defines the container with the angular neck, are pivotally mounted so that the parison can be positioned between the open mold sections in the desired location, and after the mold sections are closed on the parison, the mold sections are pivoted so that the angular neck is aligned to receive a blow pin for performing the compression molding and blowing operations.
