Abstract: In a liquid delivery device for a toilet, a container (3) for the liquid has an outlet (15) which extends into a cup (35). The cup (35) is open to the atmosphere and liquid flows into the cup (35) until the mouth (25) of the outlet is covered by liquid in the cup. The cup wall has a weir (45) and liquid in the cup (35) overflows the weir (45). A collar (61) around the outside of the cup (35) forms a capillary with the cup wall to control the flow of liquid and feed it to capillary channels on a delivery plate (9) below the level of the weir.

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 for releasing a treatment composition into the bowl of a toilet, and a fragrance into the surrounding room, comprises a solid block of a treatment composition in a housing. A block of gel material impregnated with the fragrance fills an opening in a front wall of the housing and is exposed to the housing interior.

Abstract: A dispenser (1) for releasing a liquid treatment composition (33) into a toilet bowl and a fragrance into the surrounding room comprises a container (3) holding a non-perfumed liquid treatment composition (33) for treating flush water in the toilet bowl and a fragrance releasing gel block (39) for continuously fragrancing the surrounding air.

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 cistem 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 cistem 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 cleansing block for treating water comprises from 40% to 80% by weight of a halogen release agent, from 20 to 55% by weight of a surfactant component, and from 1 to 10% by weight of a hydrophobe.
