A container cover comprises a central dome, a peripheral rim portion surrounding the central dome, wherein the central dome extends upwardly from the peripheral rim portion, a skirt extending downwardly from an outer edge of t he peripheral rim portion, and a plurality of grippers. Each gripper comprises a flange extending downwardly from a lower surface of the peripheral rim portion and at least two gripping fingers extending downwardly from the flange. The skirt and the grippers form a space for receiving an edge protrusion, for example a curled edge, of a container body. Each of the at least two fingers has a protrusion extendin g toward the skirt and the fingers are adapted to provide a gripping force to an edge protrusion of a container received in the space. The plurality of grippers are spaced from one another around the peripheral rim portion. The container cover may be combin ed with a container body having an edge protrusion at its opening.
