Abstract
A cover for a cooking vessel with a strengthened edge comprises a central portion having a downwardly depending skirt with an upper portion substantially the same outer diameter as the cooking vessel, a diametrically inwardly offset lower portion having a doubled wall thickness and a substantially horizontal offset portion formed between the upper and lower portions of the skirt. A method of forming a strengthened edge on a cover for a cooking vessel includes flattening an inwardly rolled bead formed on a cut edge of a downwardly depending skirt of a cover blank, the flattening process forming a diametrically inward offset in the lower portion of the downwardly depending skirt and mechanically sealing the cut edge of the skirt to the lower portion of the skirt.
