<p>A metal container, such as a paint can, has its ring (10), cap (14) and end (16) each made from a circular blank of the same material and having the same diameter. Preferably, all the blanks have the same thickness. The blanks are then individually shaped. This results in a slim ring-lid combination which reduces the internal pressure in the container when the cap is fitted. <IMAGE></p> |
