Abstract:

A spill-proof lid for use with a container for liquids includes a liquid chamber that has an outlet opening above and inlet opening below the plane of the lid. The chamber is constructed so that, as it extends from inlet to outlet, it travels from the outlet opening closely to the side of the cup to the bottom where it then crosses the bottom, up the other side and back to the inlet opening. 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 the preferred embodiment of the lid, the liquid chamber is substantially a single-loop helix.
