A fluid container cover includes a cap having an outer and an inner surface. The inner surface is capable of being coupled to the fluid container. A spout includes a drinking portion, an actuation portion and a curved, distal end. The spout is capable of being actuated from a first closed position to a second open position by an external force. A flexible tube is coupled inside of the spout, and has a first end and a second end. An air venting component has a nub and a plurality of air vent holes. When the spout is in the first closed position, the flexible tube is deformed preventing flow through the spout. When the spout is actuated from the first closed position to the second open position, the curved, distal end of the spout deflects the nub allowing passage of air with the fluid container.
