The opening 4 has an opening rim 10 and an opening plane 11 formed by the opening rim 10. The lid element 1 is or can be connected to the body 27 of a beverage container 2. The lid element 1 is inseparably (only destructively) connected to the beverage container 2 via a folded rim 6. The inside 9 of the lid element 1 forms the side of the lid element 1 facing the content of the beverage container 2, wherein the outside 8 of the lid element 1 forms the side of the lid element 1 facing away from the content and towards an environment 23. The opening 4 of the lid element 1 is the only outlet opening for the content of the beverage container 2.

[0062] FIG. 2 shows a lid element 1 in a perspective view. FIG. 3 shows the lid element 1 from FIG. 2 in cross-section in a perspective view. FIG. 4 shows the lid element 1 from FIG. 3 in a side view. FIG. 5 shows a first extract of the view in FIG. 4. FIG. 6 shows a second extract of the view in FIG. 4. FIGS. 2 to 6 are described jointly below. Reference is made to the statements relating to FIG. 1.

[0063] The lid element 1 has a lid panel 3 with an opening 4, a folded rim 6 running around the lid panel 3 in a circumferential direction 5 for connection to the beverage container 2, and a damping bead 7 extending circumferentially between the folded rim 6 and the lid panel 3. The lid element 1 has an outside 8 and an inside 9, and the opening 4 has an opening rim 10 and an opening plane 11 formed by the opening rim 10. The lid element 1 has a connecting region 12 which directly adjoins the opening rim 10 and runs around the opening rim 10 in the circumferential direction 5, and extends at least partly at a slope angle 13, wherein the slope angle 13 can be determined in a cross-section 14, running perpendicularly to an opening plane 11 and perpendicularly to the opening rim 10, between the opening plane 11 and a tangent 15 lying against the outside 8 or inside 9 in the connecting region 12. The slope angle 13 is more than zero angular degrees.

[0064] The lid element 1 is inseparably (only destructively) connected to the beverage container 2, or is connected therewith via the folded rim 6 for correct use of the beverage container 2.

[0065] The connecting region 12 extends from the flat lid panel 3 surrounding the connecting region 12, and up the opening rim 10 towards the inside 9 of the lid element 1.

[0066] The slope angle directly at the opening rim 10 amounts to around 10 angular degrees, and in the first portion 17 is at most 60 angular degrees.

[0067] The connecting region 12 is designed symmetrically in the circumferential direction 5, i.e. the course of the connecting region 12 is the same in all cross-sections 14. Thus in the first portion 17, the slope angle 13 present at a position 19 in the radial direction 16 is constant in the circumferential direction 5.

[0068] A first portion 17 of the connecting region 12 adjoining the opening rim 10 in the radial direction 16 extends in the cross-section 14 at the slope angle 13, wherein the first portion 17 has an extent 25 in the radial direction 16 of around one millimeter.

[0069] The first portion 17 extends in the radial direction 16 up to a second portion 18 which, in the cross-section 14, runs parallel to the opening plane 11. The second portion 18 is part of the lid panel 3.

[0070] In the cross-section 14 and in the first portion 17, the slope angle 13 varies but is more than zero angular degrees at every position 19. The first portion 17 has a curving course in the cross-section 14.

[0071] The transition between the first portion 17 and the second portion 18 is configured as a curve.

[0072] A cut edge 28 runs on the opening rim 10 in an axial direction, i.e. in a direction running transversely to the radial direction 16. This cut edge 28 is formed by a punching tool which advances in the axial direction to form the cutting edge 28. After punching, the resulting cut edge 28 is bent further so that the cut edge 28 runs sloping from the axial direction towards the radial direction 16 at a cut edge angle 31 of 20 angular degrees relative to the axial direction (only illustrated in FIG. 5).

[0073] The cut edge 28, arranged at an angle to the axial direction, allows the edges of the cut edge 28, i.e. the transition between the outside 8 and the cut edge 28 (first edge 29) and the transition between the inside 9 and the cut edge 28 (second edge 30), to be pressed into the sealing material 26 so that the sealing material 26 also extends beyond the first edge 29 towards the outside 8.

[0074] FIG. 7 shows a closure assembly 20 in a cross-sectional perspective view. Reference is made to the statements relating to FIGS. 1 to 6.

[0075] The closure assembly 20 comprises the described lid element 1 and a closure element 21 arranged on the lid element 1 for closing the opening 4. The closure element 21 with the opening rim 10 forms a sealing face 22, via which the beverage container 2 can be sealed gas-tightly against an environment 23.

[0076] The opening rim 10 extends into a sealing material 26, wherein the sealing material 26 is arranged on the inside 9 and also on the outside 8 of the lid element 1. The opening rim 10 with the sealing material 26 forms the sealing face 22.

[0077] The closure element 21 has a stop face 24 which lies permanently against the inside 9 and surrounds the opening 4 in the circumferential direction 5, wherein the sealing face 22 is arranged on the stop face 24.

[0078] The closure element 21 is attached non-releasably via the sealing material 26 to the opening rim 10 or the connecting region 12 of the lid element 1. The closure element 21 allows a repeatable gas-tight closure of the opening 4.
