ABSTRACT:
A spill-proof lid for use with a container for liquids includes a liquid chamber that has an outlet opening above and an inlet opening below the plane of the lid. The chamber is constructed so that, as it extends from inlet to outlet, it traverses the lid from edge to axially opposing edge and back again. The periphery of the lid is constructed to sealingly engage the upper edge of the container. Preferably, the outlet end of the liquid chamber has a mouthpiece formed thereon for ease of drinking. In one embodiment of the lid, the liquid chamber is substantially a single-loop helix.
