A self-sealing closure for a drinking vessel with a receptacle, said closure comprising (a) a lid having a depressed area and at least one orifice within the depressed area; (b) a shutter matching said orifice; (c) means for resiliently holding the shutter against said orifice; and (d) means rotating within a plane perpendicular to the central axis of said receptacle and lid for pushing the shutter away from said orifice in a direction substantially orthogonal to the plane of said orifice, wherein: (e) said shutter is normally in a closed position in which the passage of fluid through it is prevented; (f) said shutter can be moved from its closed position to an open position by the application of an external force, which need not exceed about 2.8 ounces, applied along the perimeter of the shutter within a plane perpendicular to the central axis of the shutter; and (g) when said external force ceases to be applied to the shutter, the shutter spontaneously returns to its closed position.
