PURPOSE: An elastomeric valve for spill-proof feeding devices is provided to minimize the trampoline effect such as leakage and/or spillage phenomenon of liquid generated when any vessels are shaken, dropped or abruptly inverted. CONSTITUTION: A feeding device(10), which is especially adapted for use by infants, toddlers and the like, includes a drinking cup(12), a lid(14), and a flow control valve(16). The drinking cup includes a body(18) and an over-molding(28) which partially covers the body to function as a bumper and to provide gripping surfaces for a user. The lid has a spoutless design which allows a user to simulate drinking from a conventional open-mouthed cup and which also maximizes liquid evacuation from the drinking cup. The flow control valve has a polygonally-shaped body with a plurality of corners, and a liquid-dispensing nipple which is located in one of the corners so that the flow control valve can be positioned adjacent to a peripheral edge of the lid, thereby promoting the complete evacuation of liquid from the drinking cup. The size, shape and rigidity of the valve body inhibits it from being inserted into the throat of a user or other individual.
