Container lid and valve

A lid configured for use with a fluid container, the lid comprising:

• a body member formed of a deformable plastic material, the body member including a central body that extends to an outer periphery, the outer periphery configured to couple to a rim of a fluid container, the body member defining an aperture therethrough adjacent the outer periphery, the central body having a top surface and a bottom surface and, the central body being deformable and downwardly deflectable upon the application of manual pressure to the top surface;
• and
• a valve having a first portion directly secured to the bottom surface of the body member and a second portion extending from the first portion, the second portion including a protuberance and being movable relative to the first portion between a free state and a depressed state in response to downward deflection of at least a portion of the central body of the body member relative to the outer periphery of the body member, the protuberance configured so as to extend into and occlude the aperture to provide for substantially sealed engagement of the aperture of the body member while the second portion is in the free state and the protuberance being spaced from the aperture of the body member so that the aperture is unsealed permitting fluid flow therethrough while the second portion is in the depressed state.
