  • Inertial spin welding of thermoplastic and thermoplastic coated container parts
    Patent number: 4584037
    Abstract: A thermoplastic container bottom is inertially spin welded into the interior of a cylindrical container body of paperboard internally lined with a layer of thermoplastic material. A body supporting mandrel has an expansible body engaging portion which is inserted into the body and subsequently expanded to define a cylindrical surface of a diameter exactly equal to that of the specified internal diameter of the body. A seating member at the end of the body supporting mandrel establishes the depth to which the container bottom is inserted into the body and is provided with a low-friction projecting resilient member which contacts the rotating bottom.

  • Bi-axially oriented, thin-walled, synthetic plastic container/article
    Patent number: 4572851
    Abstract: A method of, and apparatus for, forming thin-walled synthetic plastic containers and like articles wherein areas are stretched out of the plane of heated thermoplastic material a portion of the axial length of the containers or articles to be formed to form top and bottom preforms, each with an open and a closed end; each preform, while still in the webs, is further axially and radially stretched, at a temperature conducive to orientation of the molecular and crystalline structure of the material, to a greater length still less than the axial length of the container or article to be formed; the preforms are severed from the webs to provide open ended top and bottom sections; and the open ends of pairs of top and bottom preforms are assembled and welded together to form the containers or articles.

  • Apparatus for extruding thermoplastic compositions
    Patent number: 4560334
    Abstract: Disclosed is an apparatus for extruding thermoplastic compositions comprising an extruder, a die, and a cooling device positioned between the extruder and the die for cooling the heat plastified resinous composition exiting from the extruder to a uniform temperature desired for extrusion through the extrusion die. The cooling device includes at least one enclosed flow path for conveying the resinous composition from the inlet of the cooling device to the outlet of the cooling device, structure for circulating a cooling medium about the entire circumference of each of the resin flow paths, and flow control orifices at the inlet and the outlet of the cooling means across the entire cross-section of each of the resin flow paths.

  • Process for making a thin walled container from a plastic resin
    Patent number: 4552717
    Abstract: The process for making thin wall containers from plastic resins described herein includes the step of heating the resin, placing the resin between a product mold and a preform mold, and closing the molds thereon. It also includes the steps of applying a differential pressure across the resin to force the resin into the preform mold and applying pressure on a movable piston in the preform mold that forces the resin relatively into the product mold. As pressure is applied internally of the product being formed, the container is shaped in the desired configuration and during such formation, is biaxially oriented to improve the strength characteristics of the container.
