ABSTRACT:
A drinking vessel comprises a hollow cup having an upper rim defining a mouth opening. A lid removably mounted on the cup extends across the mouth opening to prevent spilling of liquid from the cup. The lid includes a base so mounted on the cup and having a flange extending inwardly from the cup's rim partly across the mouth opening and defining a port aligned with an inner part of the mouth opening. The lid further includes a valve element in register with the port, a seal on the valve element underlying the flange, and an actuator adjoining the valve element and disposed laterally outwardly thereof, such that when the actuator is depressed by downward force of the user's thumb, the valve element pivots downwardly, separating the seal from the flange. A spring normally biases the valve element upwardly with the seal against the flange.
