Can lid, can and method for manufacturing a can lid

A method for manufacturing a can lid for a can, comprising the following steps:

• providing a lid panel configured to delimit an upper side of the can, the lid panel having at least one pouring opening, through which a substance present in the can be poured out;
• providing an actuating element and a closure element;
• disposing the closure element on a lower side of the lid panel, the lower side facing an interior of the can when the can lid is attached thereto;
• disposing the actuating element on an upper side of the lid panel, the upper side facing away from an interior of the can when the can lid is attached thereto;
• fastening the closure element and the actuating element to one another by a connection;
• wherein:
• the closure element is movable by the actuating element between a closed position, in which the closure element closes the pouring opening in a liquid-tight or gas-tight manner, and an open position, in which the pouring opening is at least partially uncovered;
• at least one protrusion is defined in the lid panel, the at least one protrusion facing the closure element;
• and
• an air channel is formed between the closure element and the lid panel by a deflection of at least a section of the closure element at the protrusion, when the closure element is being moved towards or is in the open position.
