A closure element comprising at least one base part, a tab, and a cover;

• wherein the base part comprises a frame part having a window;
• wherein the tab is pivotably connected to the frame part by a first axis of rotation;
• wherein the cover in a starting position of the closure assembly closes the window and is connected to the frame part pivotably by a second axis of rotation or by a hinge;
• and

• wherein the closure comprises at least one base part, a tab, and a cover;
• wherein the base part comprises a frame part having a window, arranged at the opening edge;
• wherein the tab is pivotably connected to the frame part by a first axis of rotation;
• wherein the cover is connected to the frame part pivotably by a second axis of rotation within a hinge;
• wherein the tab is connected permanently to the cover by a guiding device;
• wherein the method, starting from a starting position in which the window is closed by the cover, comprises:
• pivoting the tab about the first axis of rotation,
• wherein pivoting the tab about the first axis of rotation pivots the cover about the second axis of rotation around the hinge until the cover reaches an open position to open the window
• wherein, while the window is open, liquid can flow from a first side of the lid to a second side of the lid through the window;
• and
• pivoting the tab and the cover back in order to close the window once again.
