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.
Claims8
A fluid dispenser for dispensing drinking fluid comprising:
- a bottle having an open end and a close end;
- a fluid valve disposed adjacent said open end and spaced from said close end, said fluid valve includes a float member connected thereto via an actuating arm;
- and
- a pressure-vent member removably disposed adjacent said open end and spaced from said close end, said presure-vent member having a cavity formed therethrough, said cavity being configured to receive filtering material,
- wherein during operation, said bottle maintains a predetermined fluid level therein, said bottle being made of a material whereby fluid in said bottle is visible through said bottle, said valve, float member and pressure-vent member being disposed above said fluid level, such that when fluid in said bottle reaches said fluid level, said float member buoyantly rises with said fluid thereby moving said actuating arm in one direction allowing said actuating arm to shut off said valve, and such that when fluid in said bottle falls below said fluid level, said float member buoyantly falls with said fluid thereby moving said actuating arm in another direction allowing said actuating arm to open said valve.
