Process for manufacturing a shaped metal can comprising, on one hand, a bottom (1) and a peripheral wall (2) having a succession of regions of different diameters and, on the other hand, a lid crimped or seamed on the peripheral wall (2). The process comprises producing from a metal blank a cylindrical preliminary can comprising a bottom and a peripheral wall of diameter equal to a given diameter D of a region (2A) of the peripheral wall 2 of the can, effecting a necking operation on a part of the peripheral wall of the preliminary can situated above the region (2A) of the given diameter D of the peripheral wall (2) of the formed can to bring it to a diameter D1 less than the given diameter D, and effecting at least one expanding operation on a part of the peripheral wall situated above the region (2A) of the given diameter D.
