| titleOfInvention | Method of Bonding Metallic Lap Seams and Metallic Structures produced thereby |
| abstract | 1,189,846. Jointing. GENERAL MILLS Inc. 25 May, 1967 [25 May, 1966], No. 24338/67. Headings B3J and B3V. A metallic container has at least one lap seam bonded by a thermoplastic resin composition comprising a polyamide of a polymeric fat acid of dimer content above 90 wt. per cent and a diprimary diamine which polyamide has a melting or softening point below the melting point of the metal. The polyamide may be a copolyamide including another dicarboxylic acid and numerous suitable acids and amines are specified and specific examples of the preparation of 8 suitable polyamides are given; they may have molecular weights above 10,000 e.g. 15,000 to 25,000. The metal may be steel, aluminium, tinplate, copper or bronze and may be enamelled or coated. An inert coating may be applied to the container after the seams are bonded. The polyamide adhesive may be applied to one edge of a metal blank as a strip about “ inch wide and 0À003 inch thick and the other edge overlapped to form a generally annular structure. The polyamide may be applied by an extrusion or hot melt technique, as a solution or as a sheet, film, powder or granules. The metal may be preheated. To effect the bond the annular structure may be flash heated then quickly cooled to below the melting point of the polyamide. |
