Abstract: A lid configured for use with a fluid container includes a body member and a valve. The body member includes a central body that extends to an outer periphery configured to couple to a rim of a fluid container. The body member defines an aperture therethrough and has top and bottom surfaces. The valve has a first portion directly secured to the bottom surface and a second portion that extends from the first portion. The second portion includes a protuberance and is movable relative to the first portion between free and depressed states in response to deflection of at least a portion of the central body relative to the outer periphery. The protuberance is configured for sealed engagement with the aperture while the second portion is in the free state and is spaced from the aperture while the second portion is in the depressed state.
