ABSTRACT:
The present invention is directed to a self-leveling fluid container or dispenser.
The invention can be specifically illustrated as it applies to an automatic self-leveling zero burette. A hole is drilled in a wall of the burette approximately on top of the zero graduation line. A piece of plastic tubing with a saddle base serves as a sleeve. The saddle base of the sleeve is connected to the hole in the burette. A length of plastic tubing has a first end thereof connected to the other end of the sleeve. A second end of the length of plastic tubing is inserted through a tight fitting hole in the cap of a squeeze bottle and is extended to near the bottom of the bottle. The squeeze bottle serves as fluid reservoir for fluid to be fed to the burette. When the squeeze bottle containing the fluid to be fed to the burette is depressed the fluid travels up the length of tubing and into the burette. By simply releasing the pressure on the squeeze bottle, all fluid in the burette above the zero line is sucked back into the reservoir bottle.
