ABSTRACT:
Dispensing apparatus for dispensing bleach or detergent into a toilet tank or the like on a controlled basis. The dispensing apparatus comprises a dispenser immersed in the tank water, the dispenser being subdivided into two approximately equal volume chambers, one for containing the bleach and the other for the combination of a dye with a detergent. The internal structure is such that a metered dose of a liquid solution formed from a block or cake of detergent or bleach is automatically dispensed each time the flushing of the toilet tank takes place. An intake means, including an aperture or opening, is provided at one end of each of the chambers for receiving a predetermined quantity of liquid from the tank; also there are provided barrier means or similar means internally of the chamber for retaining said quantity and keeping it isolated from the bleaching or detergent block until a flushed cycle is initiated; a flotation means in the form of a compartment within the chamber containing trapped air and located at the other end of the dispenser; exit means, in the form of an opening at that other end; and means for enabling movement of the dispenser as the level of said liquid rises and falls such that the force produced by the flotation means at the one end causes the intake means to take in a predetermined quantity of liquid, and dispensing takes place through the exit openings, in accordance with gravity, as the barrier means is overcome.
