Abstract
A molding tool is described for manufacturing a lid made of a fiber-containing material, a lid, and a molded part made of a fiber-containing material, wherein the design of the lid and of the molded part provides protection against leakage of liquids, etc., in a simple manner.
Claims14
A molding tool for manufacturing a lid made of a fiber-containing material, having at least one mold cavity bounded by at least two tool parts movable relative to one another, wherein the at least one mold cavity in a closed state forms at least one cavity for a lid to be manufactured, wherein at least one of the tool parts has at least one groove on a molding surface of the at least one mold cavity, wherein the at least one groove extends at least partially over the molding surface of the tool part in the molding direction of the at least two tool parts.
A lid made of a fiber-containing material, having an edge that has a locking portion for locking onto a container wall, and a side portion that is connected to the edge at a first region via a transition surface, wherein the side portion is connected to a closing lid surface at a second region,
- wherein the edge and the side portion have a different orientation with respect to the lid surface or the transition surface, wherein the lid includes at least one sealing lip running on an inner side of the lid in a region of the transition surface, wherein the at least one sealing lid is aligned concentrically to an axis running orthogonally through the lid surface and provides an additional holder with respect to the locking portion, wherein the at least one sealing lip and the locking portion are arranged opposite one another so as to come into contact with a container wall in a region of a container edge on opposite sides of the container wall.
A molded part made of a fiber-containing material, having an edge that has a locking portion for locking on a container edge of a container, and a lid surface, wherein the edge has a locking portion in a transition to the lid surface and the locking portion has an undercut, wherein the edge has a different orientation compared to the lid surface,
- wherein the molded part includes at least one sealing lip running on an inner side of the molded part in a region of the lid surface, which is aligned concentrically with an axis running orthogonally through the lid surface and provides an additional holder relative to the locking portion, wherein the at least one sealing lip and the locking portion are arranged in such a way as to come into contact with a container edge at least on substantially opposite sides.
