Abstract

1358334 Drawn metal containers ALUMINUM CO OF AMERICA 25 Sept 1972 [19 Oct 1971] 44252/72 Heading B3A [Also in Division B5] A hollow metal cup-like article 24, Fig. 2, e.g. a drawn metal container, a pie pan, a cap for an aerosol container closure, comprises a unitary seamless metal body having a base portion 40, Fig. 3, and a peripheral wall 42, the metal body comprising an epoxy, polyester or polyurethane adhesive layer securing to the interior surface thereof a continuous layer of a barrier material of thickness of about 1 to 4 mils comprising polypropylene, copolymers of polypropylene and ethylene or ionomers of polyolefin. A metal sheet (2), Fig. 1 (not shown), e.g. of aluminium, aluminium base alloys or steel, is supplied with an adhesive layer (4) to secure a barrier layer (6) to the metal. Catalysts may be employed with particular adhesives if necessary. The layer (6) may be formed as a film or coating and is preferably of polypropylene-ethylene copolymer with 2-10% ethylene constituent. The barrier material is subjected to electrostatic discharge treatment to improve adhesion to the metal sheet. A metal blank 10 is then severed from the formed composite sheet and is interposed between die 22 and punch 26 with the barrier layer facing towards the punch. The blank may be drawn in two stages. The blank is partially restrained between die 12 and blank holder 16, and then the drawn article is produced. A stripper ring 20 facilitates removal of the article 24 from the punch. A stressrelieving heat treatment, e.g. using induction heating, may be used to provide improved barrier material properties. The article is therefore heated in the temperature range 275-375‹ F. for 0À2 seconds to 4 minutes to eliminate undesirable microvoid structures. The article may then be ironed, trimmed and decorated according to its final use and may include a circular, rectangular or oval plan configuration.
