A cover assembly for a thermos, or other bottle, which includes a dispensing spout which is movable between a closed and an open position. The dispensing spout has an opening extending through it which becomes aligned with an opening in the cover when the spout is turned to its open position. The spout also includes a vent which becomes aligned with a vent in the cover when the spout is in its open position. The opening and vent in the cover are both closed and sealed by the spout when the spout is turned down to its closed position. The spout is held in its open and closed positions by a snap-acting leaf spring element which causes the spout to be snapped to its open or closed position when the spout is turned manually in one direction or the other. The dispensing spout may be used either to pour the contents out of the bottle, or to receive a drinking straw into the interior of the bottle.
