ABSTRACT:
A passive dispensing device for use in dosing a toilet bowl with water treatment material including a housing forming a chamber which is adapted to hold water treatment material. A reservoir is provided within the housing for holding water containing the water treatment material. A water flow path is provided between the chamber and the reservoir. A water flow passageway is provided extending upwardly away from the reservoir. The passageway has its lower end in communication with the reservoir at or adjacent its bottom wall, and its open upper end in flow communication with the toilet tank interior. The upper end of the passage way is located below the upper edge of the housing (and below the level of the water within the cistern when full). As a result, water, during the filling of the toilet tank will flow into the reservoir upwardly along the water flow path and into the chamber, via the passageway. When the cistern is flushed, a portion only of the water within the passive dispensing device (and containing said water treatment material) is discharged into the toilet tank via the passageway.
