A drinking receptacle cover comprising a slant cover plate having a top surface and a bottom surface and covering a heat insulating cup at the open top; a rim surrounding the cover plate; a valve assembly having a valve element for opening and closing a spout formed at a lowest level portion of the cover plate adjacent to the rim; a push rod for operating the valve assembly; and a return spring for urging the push rod in the anti-actuating direction. The push rod is disposed to penetrate an insertion opening formed in the rim to be retractable along the bottom surface of the cover plate. An actuating lever which is engaged with the outer end of the push rod to advance it into the inside of the rim is pivotally located on the outer side of the rim. The actuating lever has an actuating section extending along the outer side of the receptacle. The valve assembly has an engaging arm to be engaged with the push rod and a closing arm having the valve element at the free end. The valve assembly is pivotally supported, by brackets protruding from the bottom surface of the cover plate, at the trunnions protruding from the lateral sides of the engaging arm.
