  • Methods for transferring holographic images into metal surfaces
    Patent number: 7094502
    Abstract: A method for impressing holographic images or holograms in the surface of metal objects such as aluminum cans, sheet metal or metal foil. The surfaces of metal shims and print rolls bearing holograms are hardened as by coating them with thin amorphous diamond coatings or diamond like coatings so the holograms can be embossed into many thousands of metal objects with clarity and consistency.
    Type: Grant
    Filed: December 27, 1999
    Date of Patent: August 22, 2006
    Assignee: Alcon Inc.
    Inventors: Mark W. Schaefer, Thomas L. Levendusky, Simon Sheu, Robert B. Larsen, Neville C. Whittle
  • Apparatus for coating metal strip
    Patent number: 6758903
    Abstract: A method and apparatus for extrusion coating both sides of a metal strip. A metal strip, such as aluminum alloy strip, is moved through a pre-conditioner, two extrusion dies, a post-heater and a cooling system. Both sides of the strip are coated with thin coatings of thermoplastic polymers. The coated metal strip is useful for containers, such as cans and can ends, as well as for automobiles, appliances, aerospace, construction and electrical devices.

  • Transfer of holographic images into metal sporting and fitness products
    Publication number: 20040003638
    Abstract: A method for impressing holographic images or holograms in the surface of sporting and fitness products such as ball bats and bicycle frames. The surfaces of metal shims and print rolls bearing holograms are hardened as by coating them with thin amorphous diamond coatings or diamond like coatings so the holograms can be embossed into many thousands of metal objects with clarity and consistency.

  • Method for inhibiting delamination of a polymeric coating from a container body
    Publication number: 20030198537
    Abstract: A method to inhibit separation of an extruded thermoplastic polymer coating from a metallic alloy container body due to body forming operations. The container body and the extruded thermoplastic polymer coating are inductively heated causing the polymer to flow into the microsurface irregularities on the body interior surface which adheres the polymer to the body.

  • Method for reducing the occurrence of polymer strands on container ends
    Publication number: 20030198751
    Abstract: A method to inhibit the formation of polymer strands on the edge of end panels and on the edge of spouts in container ends coated with thermoplastic polymers. The ends are heated sufficiently to induce crystallite formation in the thermoplastic polymer coating. Heating renders the coating less ductile, more brittle, less elastic and less prone to feathering and angel hair formation upon opening of container tabs.
