1. A container lid, comprising: a lid surface with a top side and a bottom side,a circumferential edge, andan area for an outlet opening, wherein the outlet opening includes at least one fully or partially circumferential tear profile; anda lifting tab for at least partially opening the area, thus forming the outlet opening, wherein the lifting tab is attached, via a rivet, to the top side of the lid surface outside the area for the outlet opening, wherein the rivet is an integral part of the lid surface on the top side of said lid surface, andwherein the lifting tab has a first end section and an opposite second end section that is provided in an opening position,wherein the first end section, in the opening position of the lifting tab, can be brought into at least a partial overlap with, or is at least partially overlapping, a portion of the area for the outlet opening, andwherein the second end section is provided at a first spacing from the top side of the lid surface beyond the rivet relative to the first end section, which first spacing is not sufficient for the lifting tab to apply a force to the area via the first end section to initiate the formation of the outlet opening,wherein the lid surface further comprises at least one first locking element, separate from the rivet, protruding from the top side of the lid surface or projecting from the top side of the lid surface inward into the lid surface,wherein the lifting tab further comprises at least one second locking element, separate from the rivet, that interacts with the at least one first locking element such that pivoting of the lifting tab about the rivet can be or is prevented even if the second end section is moved into a second spacing from the lid surface that is greater than the first spacing,wherein the at least one first locking element and the at least one second locking element extend from the rivet in a direction towards the second end section of the lifting tab when the second end section is in the opening position,wherein the at least one first locking element extends in a direction towards the edge in a radial direction,wherein the rivet is configured to engage the at least one first locking element in such a way that pivoting around the rivet can be or is prevented,wherein said at least one first locking element and said at least one second locking element concurrently engage one another,wherein the lifting tab further includes a holding tongue adjacent to the first end section of the lifting tab, wherein the holding tongue holds the lifting tab to the lid surface using the rivet, andwherein the at least one second locking element is provided in the holding tongue,wherein interaction of the at least one first locking element and the at least one second locking element is such that the at least one first and the at least one second locking elements are matched in shape to engage one another to prevent pivoting of the lifting tab about the rivet, andwherein the rivet extends towards the circumferential edge of the container lid in a longitudinal dimension, and engages the at least one first locking element while at the same time the at least one first locking element and the at least one second locking element engage one another. 2. The container lid according to claim 1, wherein the interaction of the at least one first locking element and the at least one second locking element is such that the first and the second locking elements are further matched in size to engage one another to prevent pivoting of the lifting tab about the rivet. 3. The container lid according to claim 1, wherein the at least one second locking element includes one or more indentations towards the lid surface that engage a matching first locking element shaped as one or more indentations towards the bottom side of the lid surface. 4. The container lid according to claim 1, wherein the lifting tab comprises at least two, three, or four second locking elements and/or the lid surface comprises at least two, three, or four first locking elements, wherein the at least two, three, or four first and second locking elements match with respect to their position, their shape, and/or size. 5. The container lid according to claim 1, wherein the at least one first locking element and/or the at least one second locking element is provided in a region of the rivet and the second end section of the lifting tab. 6. The container lid according to claim 1, wherein the container lid is configured for a beverage can. 7. The container lid according to claim 1, wherein two or three first locking elements extend radially from the rivet towards the circumferential edge in a longitudinal dimension. 8. The container lid according to claim 1, wherein the rivet engages the at least one first locking element and the at least one second locking element so that pivoting of the rivet can be or is prevented. 9. The container lid according to claim 1, wherein the rivet extends towards the circumferential edge of the container lid in a longitudinal dimension, and further engages the at least one second locking element while at the same time the at least one first locking element and the at least one second locking element engage one another. 10. The container lid according to claim 9, wherein at least one further first locking element engages at least one further second locking element without engagement of the rivet with said further first and second locking elements. 11. The container lid according to claim 1, wherein the rivet, the at least one first locking element, and the at least one second locking element have been obtained by compression molding a blank of the rivet, which is an integral part of the lid surface, with a section of the lid surface forming the at least one first locking element and a section of the lifting tab forming the at least one second locking element—while in mutual engagement. 12. A container comprising a container body and a container lid according to claim 1 joined with the container body in a fluid-tight manner. 13. A method for producing a container lid according to claim 1, comprising: providing the lid surface having a top side, a bottom side and a circumferential edge, with the area for an outlet opening, wherein the outlet opening includes at least one fully or partially circumferential tear profile, and with a rivet blank on the top side of the lid surface as an integral part of the lid surface;providing the lifting tab with an aperture for the rivet blank;inserting the lid surface in a first compression molding die;placing the lifting tab at or onto the lid surface such that the rivet blank extends through the aperture; andcompression molding of the lid surface, including the rivet blank and the lifting tab, thus forming the rivet containing a rivet head whose dimension substantially parallel to the lid surface is greater than the aperture of the lifting tab, said compression molding also forming the at least one first locking element, separate from the rivet, protruding from the top side of the lid surface or projecting from the top side of the lid surface inward into the lid surface, and at the least one second locking element, separate from the rivet, provided in the lifting tab or the holding tongue of the lifting tab, such that the rivet, the at least one first locking element, and the at least one second locking element engage one another, thereby making pivoting of the lifting tab about the rivet difficult or preventing such pivoting. 14. The method according to claim 13, wherein the rivet head is at least partially brought into engagement with the at least one first locking element and the at least one second locking element in the process of forming the first or second locking element, respectively, in the compression molding process. 15. The method according to claim 14, wherein at least one further first locking element is brought into engagement with at least one further second locking element in the compression molding process. 16. The container lid according to claim 1, wherein the at least one second locking element interacts with the at least one first locking element when the lifting tab is in the opening position. 17. The container lid according to claim 1, wherein the second locking element and the first locking element extend in a direction away from the area for the outlet opening and from the rivet. 18.
