  • Patent number: 6543426
    Abstract: A multilayered fuel tank (10) for a motor vehicle is disclosed having a fuel tank body (32) for holding liquid and vapor fuel comprising a bottom wall (46), side walls (45) and a top wall and a plurality of fuel tank components (35) located on the top wall and seams (37) located on the side walls. A tank cover (36) is connected to the fuel tank body to define a vapor collection chamber (34). The tank cover encapsulates the top wall and the fuel tank components and seams thereby trapping any fuel vapors that may escape from the tank body, the fuel tank components and the seams. Also disclosed is a method of making the multilayered fuel tank and a method of preventing fuel vapors from escaping from a fuel tank to the environment.

  • Patent number: 6183683
    Abstract: A method and apparatus is provided to transport parisons from the extrusion die to a second location. The parison is extruded and a collar means is provided to contact the parison near its upper end and create a holding geometry whereby the parison is retained by the collar means without pinching the parison. The parison is then transported vertically or horizontally to the mold unit without closing or pinching the parison. The holding geometry is created by slightly deforming the parison wall near the collar means. The parison is therefore transported to the second location, for example a mold unit, instead of moving the mold unit, to the parison.
