An improved lid for covering containers, such as tumblers or the like, has a mouthpiece with at least a portion of the mouthpiece shaped to fit within the lips of a person drinking from the container. The mouthpiece has a valve at its base, operated by the drinker's lips, by the application of pressure on opposite sides of resilient walled containers, or by pressure on a portion of the lid. The mouthpiece, with valve on the lid, prevents spilling of the liquid, if the container is accidentally dropped, precludes spilling of the liquid during the time the drinker is engaged in drinking the liquid from the container, even when the drinking is done under adverse conditions, and provides facilitated means for adding condiments to a hot beverage for consumption by a user. Features are further provided for more effectively securing the valve to preclude inadvertent spilling from "wave action" of the liquid within the container. Means are further provided to enable the user to sense the temperature of the liquid immediately before liquid is released from the container, as well as to permit facilitated stacking of the lids while providing an alternative number of valving locations.
