A beverage can lid comprises an outer peripheral groove adjacent the outer rim and an inner concentric groove separated therefrom by a dividing rim which is at a predetermined height relative to the outer rim. A center platform is connected to the dividing rim by walls which slope downwardly from said rim. The central pull tab area is approximately the same height as the height of the inner groove and is connected to the inner dividing rim at one end with an upwardly curving surface. The outer groove which may be shallow and permits entry of a crimping tool to mount the lid on a can is also easily cleaned to provide a sanitary can lid. The inner groove may be blocked in the pouring spout area to facilitate cleaning.
