Patent number: 10471169Abstract: A dispensing screen for dispensing, by evaporation, volatile materials applied thereto, is provided. The screen comprises a sheet of material and diverting means formed in the plane of the sheet. The diverting means form a minimum path length along the length of the sheet between at least a portion of a first edge and an opposing second edge of the sheet, which minimum path length is longer than the distance between the first and second edges along the surface of the sheet. A dispensing apparatus is also provided, which in embodiments includes the dispensing screen of the invention, and in embodiments includes a sink for capturing un-evaporated volatile material.Type: GrantFiled: September 12, 2011Date of Patent: November 12, 2019Assignee: I&I DEVELOPMENTS LTD.Inventor: Brian Parry Slade

Publication number: 20080307571Abstract: A dispensing means for delivering a dose of a first liquid into a second liquid is provided, the dispensing means comprising an enclosure (2, 3, 4) for accommodating the first liquid (12, 13), and dispersion means (15, 16), the dispersion means being adapted to receive a dose of the first liquid from the enclosure, and to deliver a dose of the first liquid into the second liquid when subjected to a flow of the second liquid. The dispersion means comprises a structure (15, 16) along which the first liquid is transportable and, in use, substantially all of the surface area of the dispersion means is exposed to the atmosphere. A surface of the dispersion means is curved such that the flow of the liquid when incident upon the surface is drawn over at least a portion of the surface.Type: ApplicationFiled: July 29, 2005Publication date: December 18, 2008Inventors: Brian Parry Slade, Robert George Kinsley

Publication number: 20040217132Abstract: A liquid delivery device is particularly suited for dosing a toilet bowl with cleaning agents. Liquid from a reservoir flows through an inner sleeve of a connector into a cup until the liquid level reaches the mouth of the inner sleeve. Web is perforated so that the space in cup is open to atmosphere. Liquid is drawn from the cup by a capillary formed between the wall of cup and the connector and delivered to a porous pad. Flushwater runs over pad and supporting plate to disperse the liquid into a toilet bowl.Type: ApplicationFiled: May 24, 2004Publication date: November 4, 2004Inventor: Brian Parry Slade
