Abstract
A can end 50 is attached to a flange 16 of a can body 1 by means of a double seam. The radius r.sub.2 of the seaming panel 55 of the can end is related to the radius r.sub.1 of the body flange radius 17 by the formula EQU r.sub.2 =r.sub.1 +t where t is the thickness of the body flange. The benefit arising is that a longer body hook in the seam is achieved so that the overlap of body hook and can end is reliably increased so that reduced axial pressure may be used during formation of the double seam.
