FIELD: manufacture of cans by cold sheet forming. SUBSTANCE: body of can is made by deep drawing of flat material such as aluminium strip that may have in zone of its terminal bead layer for sealing cover of film material, for example of aluminium foil, provided with additional sealing layer. Cover is sealed at applying pressure to it and/or heating it. At sealing process additional sealing gasket is introduced. Gasket blank is formed together with body blank. When deeply drawn body of can is expanded and/or sealing gasket size is reduced, said gasket is applied onto flange of can. Can body blank may be separated from sealing gasket blank before or after deep drawing of blank. EFFECT: enhanced efficiency of process due to lowered consumption of material. 9 cl, 3 dwg
