METHOD AND APPARATUS FOR CLEANSING AND DISINFECTING TOILET TANKS AND BOWLS ABSTRACT Method and apparatus for cleansing and disinfecting a toilet tank and toilet bowl by treating the water dis- charged from the toilet tank each time the toilet is flushed. A passive dosing dispenser that automatically dispenses a disinfectant with each flush is provided in the tank to carry out the cleansing and disinfecting method. The dispenser com- prises a series of chambers in fluid communication including a reservoir containing the source of disinfectant, a vented volume control chamber, a delivery tube provided with a dis- pensing orifice in dynamic fluid communication with liquid in the toilet tank, and a vented standpipe. The respective cham- bers have volumes selected to provide a controlled dispensing action, and the arrangement of chambers is such that the con- centration of the aqueous disinfectant solution discharged re- mains substantially constant upon repetitive flushing, and/or during extended quiescent periods. The dispenser can be pro- vided with means responsive to toilet tank and toilet water con- taminants that tend to interfere with the disinfectant dis- pensed.
