Process for fabricating a can have a crimped metal cap, starting from a can body (16) of which one end has been previously shaped into an edge to be crimped (11), and from a cap (17) which has also been previously shaped to form a cup (27) extended at the periphery by an outer hem (12); the edge to be crimped (11) of the can body (16) has a cross-section, in a longitudinal plane, passing by the longitudinal axis of the can body (16), configured like an upside down V having an external wing forming a re-entrant edge (21) and delimiting an acute angle (18) with the other internal wing (19) which extends substantially in the prolongation of the wall of the can body (16); the hem (12) of the cap (17) has a section in the longitudinal plane which matches externally said upside down V by being comprised of an internal wing (29) which corresponds to the longitudinal wall of the cup (27) of the cap (17) and an external wing forming a re-entrant contour edge (22) which extends along a curved edge (28) whose concavity faces the axis of the cap (17).
