  • Process for making a multilayered parison of thermoplastic material
    Patent number: 4590028
    Abstract: A method is disclosed for making a three layered parison for blow molding a biaxially oriented hollow article of thermoplastic material. One end portion of an extruded tubular body is heated to welding temperature and closed to a bottom by a forming step. The central layer of the multilayered body is removed from part of the end portion before the forming step takes place to insure that the central barrier layer of the body allows for an intimate welding together of the inner and outer layer. A similar operation is used in making the finish portion of a container at the opposite end of the tubular body.

  • Apparatus for making a parison for blowmolding of a hollow article
    Patent number: 4566871
    Abstract: The heated end of a parison is brought into a finish mold form to shape a finish profile suitable for setting up a closure. The parison is axially stretched by a stretch pin to pull out the heated plastic material adjacent the profile to a thinner cross section. This allows to obtain a considerable saving of weight of the plastic material.
