ABSTRACT:
A lid is provided for removably mounting on the rim of a drinking cup. The lid includes a center section which overlies an area defined by the cup rim, and a peripheral section which delimits the center section and snugly fits over the cup rim. The center section is provided with a drinking portion through which a predetermined amount of the cup contents will flow. Associated with the drinking portion is a flow control means which is biased to normally assume a flow-stopping position. The control means assumes an open flow position upon a predetermined manual pressing force being applied thereto during drinking from the cup.
