  • Patent number: 4267771
    Abstract: A can printing machine of the type having a rotating assembly of mandrels contacting a rotating printing blanket for transferring decoration from the blanket to cans on the mandrels is provided with mandrel assemblies which are axially alignable with the printing blanket to permit axially uniform decoration of the cans. Each mandrel assembly comprises a rigid central member; a cylindrical sleeve mounted on the central member for receiving thereon a can to be printed; first mounting means pivotably mounting the sleeve to the central member at an axial midline of the can; and second mounting means accommodating pivoting and positioning the sleeve in a rest position to permit loading and unloading of the cans. Since the sleeve rotates relative to the central member to transfer circumferential decoration from the printing blanket to the can, the first and second mounting means permit rotation of the sleeve and rotatable pivoting.

  • Patent number: 4260419
    Abstract: A composition whereby aluminum scrap, including consumer scrap, is recycled into aluminum sheet and aluminum containers. Aluminum scrap is melted in a heated furnace to form a melt composition. The melt is adjusted to form the present composition, consisting essentially of silicon, 0.1-1.0%; iron 0.1-0.9%; manganese 0.4-1.0%; magnesium 1.3-2.5%; copper 0.05-0.4%; and titanium, 0-0.2%, the balance being essentially aluminum. Aluminum scrap comprising consumer scrap, plant scrap, and can making scrap is heated to form the melt composition, which requires a minimum amount of adjustment to arrive at the present alloy composition. The composition is suitable for fabrication into sheet having strength and formability properties making it suitable for container manufacture. Container manufacture according to the process and composition of the present invention comprises drawn-and-ironed can body manufacture and easy-opening end manufacture.

  • Patent number: 4254173
    Abstract: A secondary container packaging material for use in six pack can wraps, six pack bottle carriers, twelve pack carriers, etc., comprising a composite of a paper material laminated to a plastic film. The plastic film provides tear resistance to the composite, so that paper material may be used which has a tear resistance less than that of other secondary packaging paper materials. The reduced tear resistance allows the use of paper having a lower caliper, basis weight, and, therefore, cost than conventional secondary container packaging material. Natural kraft paper and recycled paper of 12-16 point caliper are preferred for use with the present composite. The plastic film may be 0.25-2 mils thick and is preferably formed of polyethylene terpthalate, polyethylene, polyvinylchloride, polypropylene, or cellophane. The preferred films are transparent and permit reverse printing on their inner surface to provide abrasion resistant decoration visible through the film.
