Abstract: front page image
(EN)In a metal container having at least one seam by which two overlapping metal edges are joined together, at least one of 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.
(FR)Dans un conteneur metallique ayant au moins une couture par laquelle deux bords metalliques chevauchants sont assembles, au moins l'un des bords (58) possede une couche polymere elastique (56) liee fermement au metal, de telle sorte que lorsque ce bord (58) est cousu sur un second bord (60), la couche polymere se deforme sans detruire la liaison, et se lie au second bord, creant ainsi un joint hermetique. Une couche de latex d'une epaisseur n'excedant pas 0,10 mm peut eventuellement etre incorporee. Des coutures auxquelles s'applique l'invention sont les coutures embouties, les doubles coutures interverrouillees ou les coutures longitudinales laterales. Dans le dernier cas, la couche polymere peut assurer la liaison pour fixer une couture a chevauchement simple.
