    • 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.
    • 组合饮水杯和液体盖。 杯子具有连续的,基本上圆柱形的壁和在圆柱形壁的纵向端部处的基本上圆形的开口。 用于封闭开口的可拆卸盖具有与杯的圆形开口配合的边缘。 喷嘴位于盖的圆周边缘附近,并且重物位于与喷口径向相对的周向边缘附近。 当圆柱形壁搁置在表面上时,重力将径向旋转杯子和盖子,使得重物将朝向表面旋转,并且喷口将旋转远离表面。
