Abstract
Method and apparatus for cleansing and disinfecting a toilet tank and toilet bowl by treating the water discharged 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 comprises 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 dispensing orifice in dynamic fluid communication with liquid in the toilet tank, and a vented standpipe. The respective chambers have volumes selected to provide a controlled dispensing action, and the arrangement of chambers is such that the concentration of the aqueous disinfectant solution discharged remains substantially constant upon repetitive flushing, and/or during extended quiescent periods. The dispenser can be provided with means responsive to toilet tank and toilet water contaminants that tend to interfere with the disinfectant dispensed.
