Abstract: A lid consisting of fibrous material, in particular of fibrous material containing cellulose fibers, for at least partly covering an opening of a container is provided. The lid comprises a domed portion which is configured to at least partly cover the container opening and an attachment portion which externally surrounds the domed portion at least in portions. The lid attachment portion is configured to attach the lid to a counter attachment portion in the region of the opening of the container, preferably on an opening edge delimiting the container opening of the container. The lid can be formed at least in portions, preferably completely, from a uniform material with respect to its constituents, and the lid can have material characteristics which differ in different regions within a portion of a uniform material composition.

Abstract: The present invention relates to a lid (10) consisting of fibrous material, in particular of fibrous material containing cellulose fibres, for at least partly covering an opening (30) of a container (28), comprising a domed portion (12) which is configured to at least partly cover the container opening (30), and comprising an attachment portion (14) which externally surrounds the domed portion (12) at least in portions, preferably completely, and is configured to attach the lid (10) to a counter attachment portion (26) in the region of the opening (30) of the container (28), preferably on an opening edge delimiting the container opening (30), of the container (28), the lid (10) being formed at least in portions, preferably completely, from a uniform material with respect to its constituents, the lid (10) having material characteristics which differ in different regions within a portion (12, 14, 20, 24, 32, 38, 40) of a uniform material composition.
