ABSTRACT:
A controllable dispenser which dispenses an aqueous solution of a soluble substance. The dispenser has an inlet to accept a supply of water and an outlet to discharge the solution. The dispenser includes a container having a chamber, where the soluble substance is placed, and a passage surrounding the chamber. The chamber is longitudinally in line with the inlet and outlet. The water entering the device is able to flow through both the chamber and the passage. The fluid flowing through the passage functions as a carrier of the solution to the outlet. The chamber is defined at both ends by an orifice. Various chambers may be used, each having a different diameter and different size orifices, one allowing a greater rate of flow than another, thereby increasing the level of concentration or the rate of solubility. The device is preferably constructed of a transparent material which enables the user to observe the amount of soluble substance remaining in the chamber. The apparatus may be used with soluble substances such as fertilizers or pesticides in various forms including granules, pellets, and plugs.
