Abstract
A toilet cleaning dispenser system adapted for placement in a toilet tank includes a hanger, a dispenser housing and a cartridge device removably coupled to the dispenser housing. The cartridge device, which includes a cleanser tablet enclosed within a cartridge housing, is inserted into a cavity of the dispenser housing and turned in one direction to lock the device and, alternatively, in an opposite direction to unlock the device. The cartridge housing may be formed to turn as one unit, or be formed as a basket and a rotatable cap that can be turned with respect to the basket. The dispenser housing includes an inlet water trap and an outlet water trap, each comprising a pair of concentric, nested tubes that retain liquid after flushing so as to prevent fumes from exiting the dispenser housing into the toilet tank.
