To provide a method for forming uneven pattern on a side wall of a metal by which the number of metallic dies of an inner die is considerably reduced, and rugged pattern can be formed on the side wall the metal can commonly using the inner die and changing only an outer die if the diameter of the can is the same when forming the rugged pattern on the side wall of the barrel portion of the metal can, and to provide a metallic die for the method.
In the method for forming the rugged pattern on the side wall of the barrel portion of the metal can by disposing the inner die 1 with the rugged pattern cut in the outer surface thereof within a bottomed cylindrical metal can body 4 formed by drawing or ironing a metal plate, and pressing an elastic outer die 22 against the inner die from the outer side across the metal can body, the inner die of the height enabling the pattern to be formed on the metal can of the largest height among the metal cans to be worked is used, and the outer die having a pressing part only in a desired area is used.
