Abstract
Abstract A lid for a drinking cup or other container wherein the lid has a restricted opening through which the contents of the container may be drunk while leaving the lid in position to prevent spillage or sloshing out of the container. The opening is covered by a flap which may be integral with the lid and separated therefrom by break lines or tear lines. The flap extends up to the edge of the cup and where a flange is provided, extending even over the flange. The flap when folded back on the hinged line opposite the rim of the lid to reveal the opening, is automatically caught against the outer surface of the lid away from the opening so that it will not interfere with drinking from the cup and so that any reason for tearing off the flap and discarding it separately from the cup is removed.
