Abstract
A drinking-fluid dispenser includes a bottle disposed on a dispenser base. Mounted inside the bottle is a valve proximally connected to a float by an actuating arm. The valve is positioned above the fluid inside the bottle and is connected to a continuous-flow fluid source. During normal use, the float which buoyantly floats on fluid, closes and opens the valve, respectively, when the fluid rises and falls inside the bottle. There is also a pressure-vent unit having an orifice and is disposed through the bottle above the bottle fluid to maintain atmospheric pressure inside the bottle.
