Abstract
A lid for closing a container is provided. The lid may be deep-drawn from a plastics material film or produced in an injection-molding method. The lid includes a substantially downwardly directed edge flange for engaging over a thickening that encircles the container's upper edge. The edge flange can be formed to be inclined outwardly at least slightly and is provided with a plurality of inwardly directed projections capable of engaging under the thickening of the container. The lid also comprises a plurality of depressions. The depressions have a depth that is greater towards an interior lid area than towards the edge flange. The depressions have width that is greater towards the interior lid area than towards the edge flange.
