Liquid dispensing apparatus and method

摘要

An apparatus (10) and method are disclosed for dispensing a first liquid (26) into a second reservoir liquid (30). The apparatus comprises a container (12) adapted to hold the dispensable liquid, a dispensing nozzle (14) and a sensing tube (18). The dispensing nozzle is positioned on the container below the dispensable liquid level (28) within the container. The sensing tube has first (20) and second (22) open ends, the first open end positioned above the dispensable liquid level within the container and the second open end positioned outside the container and below the dispensing nozzle. The second open end of the sensing tube is immersible in the reservoir liquid, whereby the cyclic fall and rise of the reservoir liquid results in the controlled discharge of the dispensable liquid from the container through the dispensing nozzle. The method comprises the steps of providing a container as described above, locating the container above the reservoir liquid, and causing the reservoir liquid to rise and fall to discharge the dispensable liquid from the dispensing nozzle.
