A cover for containers made of stiffened deformable material, for example from cardboard, has an annular rim and a plate having a depending flange. The rim has an upper portion, an intermediate portion and a lower portion. The depending flange is positioned adjacent to the intermediate portion. The lower portion is folded around the lower edge of the depending flange and pressed thereto. A three-layer structure of the downwardly extended lower rim insertable into the container provides a highly rigid cover.
