CA 1144492

ABSTRACT In a metal container having at least one seam by which two overlapping metal edges are joined together, at least one Or the edges (58) has a resilient polymeric layer (56) bonded firmly to the metal, so that when that edge (58) is seamed to a second edge (60) the polymeric layer deforms without destroying the bond, and becomes bonded to the second edge, so creating a seal against leakage. A layer of latex no greater than 0.10 mm thick may optionally be included. Seams to which the invention is applicable include swaged seams, interlocked double seams or longitudinal side seams. In the latter case the polymeric layer may provide the bond to secure a single lap seam.
