A sealing device (2, 2', 2") to be arranged between an opening in a drinking container (1', 1") and a drinking straw (20), and a method of making the sealing device (2, 2', 2"). The sealing device (2, 2', 2") comprises a region of the drinking container (1', 1"), or a part connected to the drinking
A sealing device (2, 2', 2") to be arranged between an opening in a drinking container (1', 1") and a drinking straw (20), and a method of making the sealing device (2, 2', 2"). The sealing device (2, 2', 2") comprises a region of the drinking container (1', 1"), or a part connected to the drinking container (1', 1"), made from a material (14) subjected to a plastic deformation in a portion spanning said opening in the drinking container (1', 1"). The deformation has the form of a bulge (2a) of thinned material (4). The bulge (2a) is folded upon itself to form a ring-shaped fold (12) on the inside of the drinking container (1', 1"). The fold (12) encircles the plastically deformed and thinned wall material (4) of bulge (2a), said bulge material (4) forming an inner seal ring (19) around the drinking straw (20) when the bulge material (4) is perforated.

The invention claimed is: 1. A sealing device for a drinking container or for a part configured for connection to a drinking container, said sealing device comprising: a plastically deformable material comprising a portion that is plastically deformed so as to form a bulge of thinned wall material
The invention claimed is: 1. A sealing device for a drinking container or for a part configured for connection to a drinking container, said sealing device comprising: a plastically deformable material comprising a portion that is plastically deformed so as to form a bulge of thinned wall material that spans said portion of the plastically deformable material, said sealing device defining an opening for a drinking straw when the drinking straw is inserted through the bulge of thinned wall material; wherein the bulge of thinned wall material is folded upon itself to form a ring-shaped fold on the inside of the drinking container or the part configured for connection to the drinking container; wherein the fold encircles the plastically deformed and thinned wall material of the bulge, said bulge of thinned wall material forming an inner seal ring around the drinking straw when the bulge of thinned wall material is perforated by the drinking straw; wherein an outer seal ring of the fold is reinforced by attaching all or parts of the inner surfaces of the fold to each other. 2. The sealing device according to claim 1, wherein the outer seal ring encompasses the drinking straw when the drinking straw is inserted through the device. 3. The sealing device of claim 1, wherein the inner seal ring is more flexible than the outer seal ring. 4. The sealing device of claim 1, wherein the inner and outer seal rings together increase resistance to withdrawal of the drinking straw. 5. The sealing device of claim 4, wherein during withdrawal of the drinking straw from the sealing device, the inner seal ring folds together with the outer seal ring to increase resistance to withdrawing of the drinking straw. 6. The sealing device of claim 1, wherein the device comprises part of a drinking bag. 7. The sealing device of claim 1, wherein the device comprises part of a drinking carton. 8. The sealing device of claim 1, wherein the device comprises a removable seal for attachment to a drinking opening on the drinking container. 9. The sealing device according to claim 1, wherein the material of the sealing device is made from two or more material layers having different properties.
