A cup shaped cover and valve assembly is provided for a drinking receptacle to close off the open top of the receptacle to prevent spilling or splashing of either hot or cold beverages in the receptacle. The cover includes a plate surrounded by a rim, the plate being slightly tilted in the rim so that its top surface slopes between diametrically opposite points on the rim. An elongated opening is provided in the plate adjacent to its lowest level portion and a valve head in turn positioned beneath the plate to close the opening. The valve head is biased against the opening by resilient integral supporting arms secured to the bottom of the plate. The assembly is completed by an actuating member passing into one side of the rim diametrically opposite the beverage opening in the plate, this actuating member passing beneath the plate and terminating in a camming surface such that inward movement of the member cams the valve head away from the bottom of the plate to open the opening and permit drinking of the beverage. Releasing of the member permits the resilient supporting arms for the valve head to close off the opening.
