ABSTRACT:
An infant cup includes a cup body12, a cover16, a flexible mouthpiece24and a valve element26. The valve element26includes a sealing face70which closes an orifice44in the mouthpiece in a relaxed position. The valve element includes an angled face cooperating with an internal angled face of the mouthpiece such that when pressure is applied the valve element moves downwardly, opening the mouthpiece orifice44. The valve element is resiliently biased upwards such that when relaxed it springs back to close the mouthpiece orifice44once again, and is biased upwards in the closed position.
