ABSTRACT:
An anti-spill drinking cup lid flexes inwardly, without the use of a vent hole, responsive to drinking suction applied by the cup user. The flexing is by means of a central raised portion of the lid, separated by a flex line from radiating ribs which separate slightly to enlarge the cup lid diameter when liquid is withdrawn through a raised drinking spout provided with apertures sized to prevent passage of liquid. The apertures are located in a valley in the spout end to prevent splash leakage.
