The invention is directed to a lid for a container, in particular to a lid for a drink container such as a paper cup. The lid is detachably mountable onto the edge of an opening of the container. The lid comprises a lower lid part with an inner outlet opening, and an upper lid part with an outer outlet opening. In an assembled position, the upper lid part is mounted rotatable relative to the lower lid part between at least two positions, such that the outlet openings are mutually aligned in one position and are without any overlap in the other position. The lower lid part has a circumferential mounting flange for overlapping the opening edge of the container, and the upper lid part has a circumferential mounting flange for overlapping the mounting flange of the lower lid part.
