ABSTRACT:
The invention relates to a float controlled dispenser capable of segregating active ingredients and dye and selectively releasing a predetermined amount of each into the tank of a toilet. The dispenser comprises a float operated dispenser having the fluid disinfectant in the main body of the dispenser and the dye in a separate portion of the dispenser. A mixing chamber communicating with the tank water is provided beneath the float so that, on the upstroke, water rising in the chamber serves to dissolve the dye and raise the float. A solution of dye and water is retained in the mixing chamber. During the flush cycle, as the float is lowered on the downstroke due to a decreasing water level in the tank, a measured amount of disinfectant is released from the body of the dispenser into a metering chamber on the float. As the float rises with the water level and seals the dispenser orifice, this measured amount is transferred to the surrounding tank. The dye mixture retained in the chamber is dispensed on the downstroke, at which time the decreasing water level in the toilet tank draws the mixture from the chamber into the tank.
