11 . The can lid according to claim 3 ,

wherein the actuating element has at least one fastening section, in which the connection with the closure element is formed, and a handle section connected thereto configured for gripping for repositioning between the open position and the closed position; and

wherein the fastening section and the handle section are connected by a film hinge, wherein the handle section is configured to be pivoted about a hinge axis relative to the fastening section for repositioning between a stowed position and an actuating position.

12 . The can lid according to claim 11 , wherein a hinge axis of the film hinge extends transversely to a longitudinal axis of the guide slot.

13 . The can lid according to claim 11 ,

wherein the handle section has a starting position;

wherein the actuating element is configured such that the handle section can no longer be permanently repositioned back into the starting position after it is initially repositioned from the starting position;

and/or

wherein the actuating element is configured such that it plastically deforms, in particular permanently and/or permanently visually recognizable, when the handle section is initially repositioned from the starting position.

14 . The can lid according to claim 1 ,

wherein the actuating element has a locking section by which the actuating element is locked in the closed position on the lid panel prior to an initial repositioning from the closed position to the open position.

15 . The can lid according to claim 1 , wherein the closure element and the actuating element are made of a metallic material.

16 . The can lid according to claim 6 , wherein the protrusion is a protrusion of the actuating element that protrudes in the direction of the lower side of the lid panel, and wherein the protrusion extends at least partially through a guide slot, which is defined in the lid panel, in at least one of the open position and the closed position.

17 . The can lid according to claim 9 , wherein the seal is at least partially received in a groove which is formed on an upper side of the closure element.

18 . The can lid according to claim 9 , wherein the seal is fixed to the closure element by an outer edge of the closure element, the outer edge being bent into the seal and/or over a section of the seal.

19 . The can lid according to claim 11 , wherein the handle section is pivotable between the stowed position, in which the handle section is disposed substantially parallel to the lid panel and/or to the fastening section, and the actuating position, in which the handle section is grippable for repositioning between the open position and the closed position.

20 . The can lid according to claim 1 , wherein a sealing effect of the closure element with the lower side of the lid panel is overcome along at least at a section of the closure element which is deflected at the protrusion.

21 . The can lid according to claim 1 , wherein the at least one protrusion is configured as a circumferential bead.

22 . The can lid according to claim 1 , wherein the at least one protrusion is configured to deflect at least sections of the closure element downwards.

23 . The can lid according to claim 1 , wherein the closure element or the lid panel is configured to elastically deform upon deflection at the protrusion to form the air channel.

24 . The can lid according to claim 1 , wherein the closure element is configured to tilt downward upon deflection at the protrusion to form the air channel.

25 . The can lid according to claim 1 , wherein an end region of the closure element or the protrusion on the lid panel is configured as a ramp for lifting a section of the closure element off the lid panel upon deflection at the protrusion.

26 . A can, comprising at least one can lid according to claim 1 .

27 . The can according to claim 26 , wherein an outer circumferential edge of the lid panel is crimped to a lateral wall of the can.
