Abstract
A cover is mounted in a leakproof manner over the open mouth of a drinking container. An opening is formed through the cover in the area of the circumference of the cover. A closure member is slidably mounted on the cover for movement over the opening whereby the container is rendered spill-proof and for movement to a position free from the opening whereby a user may pour and drink liquid in the container through the opening in the cup.
