The invention relates to a method of producing a tinned food container wherein the container body 1 consists of a flat material, especially aluminium strip or tinplate strip which is deep-drawn and which, at least in the region of its planar end flange, is provided with a coating 2, especially a sealing coating, and wherein a cover 4 is provided with a further coating, especially a further sealing coating, and consisting of a foil material, especially aluminium foil, is sealed on to the edge flange under the influence of pressure and/or heat. To make the production method more economical, it proposed that for producing a container body with an intermediate sealing layer 3 additionally inserted during the sealing-on operation, first the blank for the container body 1 and intermediate sealing layer 3 is punched in one piece out of the flat material, with the intermediate sealing layer 3 subsequently being separated from the container body 1 in the region of the edge flange, and that then, after the deep-drawn container body has been expanded towards its edge flange and/or after the dimensions of the intermediate layer have been reduced, the intermediate sealing layer 3 is placed on to the edge flange. |
