Abstract
A combination drinking cup and lid for liquid. A cup has a continuous, substantially cylindrical wall and a substantially circular opening at a longitudinal end of the cylindrical wall. A removable lid for closure of the opening has an edge mating with the circular opening of the cup. A spout is located near the circumferential edge of the lid and a weight is located near the circumferential edge radially opposed from the spout. When the cylindrical wall rests on a surface, the force of gravity will radially rotate the cup and the lid so that the weight will rotate towards the surface and the spout will rotate away from the surface.
