  • Patent number: 8927477
    Abstract: A sanitary agent for treatment of a sanitary appliance includes a solid or semi-solid active body, designed to adhere to a wall of the sanitary appliance and including a treatment compound having at least an active element for treatment of the sanitary appliance. The body has an external surface thereof covered by a water-soluble film. In this way, the sanitary agent can be manipulated by hand for application thereof to a moist ceramic wall of a sanitary appliance to be treated, without the user's hands entering into contact with the components of the sanitary agent itself. Furthermore, any undesired loss of the components of the sanitary agent is avoided; these can be due to deformation of the sanitary agents before use thereof, displacements thereof and/or any dripping. A method for applying the sanitary agent for deterging, disinfecting and/or perfuming the sanitary appliance is also provided.

  • Patent number: 8032953
    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.

  • Patent number: 8015628
    Abstract: Disclosed is a dispenser for dispensing a composition in response to level changes in a liquid in a tank. The dispenser includes a container for holding the composition, a discharge conduit in fluid communication with the container, an air inlet in fluid communication with the container, and a level sensing member mounted to the dispenser such that a lower end of the level sensing member contacts the liquid in the tank and senses its level. In use, a rise of the liquid in the tank between a lower liquid level and a higher liquid level causes the level sensing member to alter air pressure in a headspace of the container above the composition and thereby cause a controlled discharge of the composition from the discharge conduit; and a fall of the liquid in the tank between the higher liquid level and the lower liquid level causes the level sensing member to alter pressure in the headspace and thereby causing air to be vented into the headspace from the air inlet.

  • Patent number: 7007312
    Abstract: Provided is a hydraulic time release system for regulating the flow of liquid therethrough. The time release system comprises a timer body having a timer inlet for providing liquid at a timer inlet flow rate and a timer outlet for discharging liquid at a timer outlet flow rate. The timer body is divided into a first reservoir, a second reservoir, a third reservoir and a float reservoir. The first reservoir includes a catch pan mounted on an open drain tube that is positioned below the timer inlet. The first, second and third reservoirs are in at least partial fluid communication with the float reservoir. A timer float assembly is moveable between open and closed positions in response to variations in the float reservoir liquid level. The closed position is such that the flow of liquid into the drain tube is blocked causing the timer body to fill with liquid whereupon the timer outlet flow rate is substantially equivalent to the timer inlet flow rate.

  • Publication number: 20040128750
    Abstract: An automatic liquid dispenser dispenses precisely measured amounts of cleaner/deodorizer into a toilets tank through a closed system is further disclosed. The invention consists of a housing that connects between the water supply line and the water supply inlet of a toilets tank and a refillable liquid storage container. The housing is installed in the flow path of the water supply used to fill a toilets tank for flushing. During the filling of the toilets tank the flow of water is directed over an orifice causing a siphon to be created. This siphon compresses a spring loaded ball check allowing liquid cleaner/deodorizer to flow into the water supply filling the toilets tank When the tank is full it contains a predetermined and precisely mixed amount of water and cleaner/deodorizer.

  • Patent number: 6748610
    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.
