A spill-proof covered drinking container has an annular protruding drinking spout that provides a relatively large number of separate drinking ports around the spout circumference. An annular suction-responsive valve means is located within the drinking spout for controlling outflow of liquid through the drinking ports, such that liquid flow is confined to the port, or ports, in physical contact with the user's mouth. The user can drink from any point around the spout circumference.
