Disclosed is a lid for a container which is designed to allow drinking of the contents while the lid is in place and to prevent spillage of the contents. The lid includes a generally circular body member and a sealing edge located along the periphery of the body member. A raised platform is integrally formed on the body member and is bounded by the periphery of the body member and an upstanding wall portion generally defined by a chord of the body member. A flipper valve is located on the platform and is generally radially aligned and hinged near the wall portion. The valve includes an integrally formed protrusion which provides a place for application of downward pressure to open the valve. The valve is such that lip pressure is sufficient to cause the valve to open. The platform provides a flat area extending to the edge of the container which allows the lip to make a complete seal over the portion of the lid which it contacts. A plurality of stacking lugs whose upper surfaces are equal in elevation to the top of the protrusion on the valve with respect to the body member, can be located on the body member in order to define, along with the top of the protrusion, a stacking plane for the lid.
