The valve assembly (16) includes a drinking valve (50), a venting valve (60), or both. When in use, the valve assembly (16) engages with the lid (14) to prevent leaks or spills and to permit the flow of air into the cup. When not in use, the valve assembly (16) disengages from the lid (14) and the valve (50, 60) is open to facilitate proper cleaning of the valve assembly. |
