Abstract: A liquid dispensing device for use in the flush cistern of a water closet comprises a reservoir (13) for the liquid formulation which is fed from an inverted container (5) maintaining a constant liquid level (47) in the reservoir (13) at the mouth (37) of the container. A displacement body in the form of a piston (9), which may be magnetic, moves in a bore (56) to dispense liquid through opening (25). The piston (9) is moved by a float (11) which moves up and down as the level of water L in the cistern rises and falls on flushing. The float is coupled to the piston (9) magnetically. In another embodiment a direct mechanical coupling is used. Liquid seeps past piston (9) when in the lowered position, and is raised to overflow outlet (25) when the cistern fills. In another embodiment, liquid is dispensed on a downward stroke of the piston. The fit of piston (9) in the bore allows liquid to seep slowly past the piston to replenish the bore.

Abstract: A dispenser is provided for dispensing cleaning chemicals such as toilet bowl cleaners. It has a dosing chamber containing therein a floating shuttle that seals a lower opening in the dosing chamber and floats up there from as an aliquot of chemical is prepared for release during the next cycle. There is also a float controlled external valve head at a lower end of the dispenser for alternately opening and closing a lower opening in the dosing chamber. The level of water in the toilet tank controls the movement of the valve head, and dispensing of the cleaner chemical controls movement of the floating shuttle. A grommet provides a valve seat for both the floating shuttle and valve head.

Abstract: The present invention is to provide a dispensing device comprising a dispenser having an upper channel and a bottom opening for storing liquid cleaner; a connecting cup extended downward from the dispenser including at least one aperture on a bottom thereof; and a float in the connecting cup opposite the bottom opening. While the dispenser is mounted in a toilet tank, the float is adapted to either engage with or move away from the bottom opening as the water level in the toilet tank rises or falls. As such, the dispenser is adapted to automatically dispense liquid cleaner to the toilet tank or stop dispensing liquid cleaner to the toilet tank as the float falls or rises.

Abstract: A toilet tank cleanser dispenser has a receiving holster suitable to receive an inverted container of cleaning composition and suitable to dose liquid from the container. The adapter has an internal dosing shuttle for metering an aliquot of cleanser through an opening at the bottom of the adapter defining a valve seat. A float can move up and down with respect to the liquid level in the tank to drive an outlet valve against an outlet of the adapter. The valve head can have a balloon-like structure driven by the float. For example, a low density thin wall polyethylene valve head can be supported by a trapped air pocket to reduce leakage, permit some flexibility, and avoid permanent deformation.

Abstract: The apparatus consists of a mechanism for supplying water to the toilet and flushing water into lavatory, a vessel with solid cleaning detergent in a saturated solution, a portioning mechanism and a water supplying mechanism. The portioning mechanism supplies equal portion saturated or strong detergent solution into tank with every flush. The water supplying mechanism adds water into the vessel and keeps high level of the detergent solution in the vessel. Because the vessel consists several solid detergent tablets and it is full of saturated detergent solution, and because the portion of the detergent solution pouring into the toilet tank is a small fraction of the volume of the solution in the vessel, and an equal portion water has been supplied after each, the solution of the detergent is always saturated. Because the portion of the detergent solution dispensed is always equal the concentration of the detergent in the water of tank is always equal until the last tablet is dissolved.
