Patent number: 8291523Abstract: 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.Type: GrantFiled: March 13, 2007Date of Patent: October 23, 2012Assignee: Jeyes Group LimitedInventor: Peter Virica

Patent number: 8015628Abstract: 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.Type: GrantFiled: January 15, 2009Date of Patent: September 13, 2011Assignee: S.C. Johnson & Son, Inc.Inventors: Daniel N. Campau, Michael C. Fryan, Steven A. Zach, Douglas A. Soller

Patent number: 6948193Abstract: An improved lavatory cleanser dispensing device that is height-adjustable and capable of quantitatively dispensing cleanser is composed of a fixing member and a shell. The fixing member includes a hanging portion at a top side thereof to be hung on a toilet water tank and a plurality of locating portions formed at a bottom section thereof and in top-down arrangement. The shell includes at least one chamber inside, a plurality of inlets and outlets running therethrough to enable the chamber to communicate with outside, and at lease one positioning portion detachably mounted on the locating portions of the fixing members.Type: GrantFiled: January 2, 2004Date of Patent: September 27, 2005Inventor: Johnson J. Y. Hsu

Patent number: 6748610Abstract: 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.Type: GrantFiled: October 25, 2002Date of Patent: June 15, 2004Assignee: S.C. Johnson & Son, Inc.Inventors: Steven A. Zach, Kevin Harrity

Publication number: 20030041369Abstract: A dispenser for dispensing metered amount of liquid into a toilet cistern, comprising a basin adapted to receive a metered amount of dispensable liquid received from a container via a discharge spout. An airlock prevents further discharge of liquid above a predetermined amount in the basin when the discharge spout is covered by the dispensable liquid. A siphon inlet is in liquid communication with the metered amount in the basin, and the siphon outlet is in liquid communications with the cistern water at quiescent times. Upon flush, the siphon siphons out the dispensable liquid in the basin, breaking the airlock, and allowing a new metered amount of dispensable liquid to flow to he basin, ready for next flush.Type: ApplicationFiled: October 22, 2002Publication date: March 6, 2003Inventor: Levanon Benayahoo
