Abstract:
An improved easily openable end for a metal container, and aL method of manufacturing the end are disclosed. The metal container is manufactured from a can body and two can ends, one of which is easily openable. The easily openable can end is manufactured from a metal substrate having a score line on its external surface that permits easy removal of at least a portion of the can end from the can body. The score line of the easily openable can end is coated with a iradiat ion- curable coating composition that impa~ts corrosion resistance along the score line of the easily openable can end.
