Abstract
A drop dispensing device includes a liquid ejection system, such as a timed pump mechanism, and a multi-channeled nozzle cooperative with the ejection system, for directing ejected liquid out of a container and into a chamber external to the container wherein the nozzle further includes drip tabs for forming and directing drops. The chamber is divided into a plurality of cavities and is formed by a plurality of interconnected walls. The chamber is adapted to receive the nozzle and includes a raised drainage orifice for each cavity such that the drainage orifice is operatively coupled to a guide tube for simultaneously guiding draining drops from the chamber to a plurality of selected surfaces.
