The process further comprises the step of forming at least one bulge (22) on one of the extension (21) of the lid (2) and the sidewall (11) of the mouth (13) after fitting the lid (2) in the mouth (13) of the can (1), wherein while the lid (2) is removed from the can (1), the convex surface of the at least one bulge (22) is engaged with the other of the extension (21) of the lid (2) and the sidewall (11) of the mouth (13) in such a way that the extension (21) and/or the sidewall (11) is destroyed.
