A lid for use with a fluid container includes a body member and a valve. The body member defines an aperture and includes a central portion that extends to an outer periphery configured to couple to a rim of a fluid container. In one embodiment, the body member and the valve and connected by an interconnecting portion which are formed as an integral single piece structure. The valve has a first portion directly secured to the bottom surface of the body member and a second free end portion that extends from the first portion. The second free end portion includes a protuberance and is movable relative to the first portion between a free state in which the protuberance seals the aperture and a depressed state obtained in response to downward deflection of the central portion of the body member relative to the outer periphery in which the aperture is unsealed.
