Abstract

A drinking-fluid dispenser includes an uprightly oriented bottle having an open end and a close end. Mounted inside the bottle adjacent the open end is a valve connected to a float by an actuating arm. There is also a pressure-vent unit insertably disposed near the open end of the bottle for maintaining atmospheric pressure above the fluid inside the bottle. During normal use, fluid extracted out of the bottle is replendished by an external fluid source which is in fluid communication with the bottle through the valve. The valve in turn is controlled by the float which buoyantly floats on the fluid, closes and opens the valve, respectively, when the fluid rises and falls inside the bottle.
