<p>A replaceable valve member for a sippy cup assembly is disclosed. The valve member is a flexible, resilient member for releasable mounting in the lid of the sippy cup. It includes a normally closed, but openable slit located within the sippy cup's spout when the valve member is in its operative position. The valve member includes another normally closed, but openable slit located at a vent in the sippy cup's lid when the valve member is in the operative position. The two slits open when suction is applied to the spout to enable liquid to be withdrawn through the spout. A recess is provided in a portion of the periphery of the valve member to preclude the trapping of residual liquid in the sippy cup. The valve member also includes an opening for releasably mounting it on a handle of the sippy cup in a storage position.</p> |
