Abstract: The invention relates to a can lid consisting of a lid ring and a lid membrane having an end face, wherein the lid ring has an annular flange configured as a flattened roll on its inner periphery and surrounding an opening, the end face of said annular flange being directed radially outward and the lid membrane being connected with the annular flange so as to be flat for sealing the opening. A can lid designed according to the present invention should result in fewer injuries during normal handling and should be more resistant to corrosion as a result of the folding under of the peripheral area of the lid membrane.
