Patent number: 6806244Abstract: Composition for use in a water tank in the kitchen or sanitary sector, characterized by a basic composition essentially evolving its function following addition to a first water filling of the water tank, in the form of a tablet and at least one particle, with at least one core, which comprises at least one substance evolving its function essentially following an at least partial emptying of the first water filling from the water tank and the inflow of fresh water and a covering substantially completely surrounding the core or cores comprising at least one compound, whose solubility increases with decreasing concentration of a specific ion in the surrounding medium, the at least one particle being so arranged in or on the tablet that the surface of the particle or particles is at most only partly in direct contact with the surface of the basic composition surrounding the same and the concentration of the specific ion in the local environment of the particle or particles is sufficiently high up to a substantiaType: GrantFiled: April 18, 2001Date of Patent: October 19, 2004Assignee: Reckitt Benckiser N.V.Inventors: Guido Waschenbach, Ralf Wiedemann, Enric Carbonell, Edgar Endlein, Karl-Ludwig Gibis

Patent number: 6730647Abstract: A composition is provided for use in a dishwashing machine and in the form of a tablet. The composition is characterized by having at least two small parts, which are placed in or on the tablet, and in which at least one functional substance is concentrated in each case thus enabling the respective small part to be released by dissolution at a determined point in time during the dishwashing cycle. The small parts are produced by using at least two different methods.Type: GrantFiled: June 28, 2002Date of Patent: May 4, 2004Assignee: Rackitt Benckiser N.V.Inventors: Guido Wäschenbach, Harald Magg, Richard Neergaard, Enric Carbonell, Ralf Wiedemann

Patent number: 6730646Abstract: The invention relates to a composition for use in a dishwasher which is provided in the form of a tablet. The inventive composition is characterized by a base composition which essentially carries out its function during the main cleaning cycle of the dishwasher, and is also characterized by at least one particle. Said particle has at least one core that comprises at least one substance which essentially carries out its function during the rinse cycle of the dishwasher. The particle also has a coating which, for the most part, completely surrounds the core(s). Said coating comprises at least one compound whose solubility increases with a declining concentration of a specific ion in the surrounding medium. The at least one particle is arranged in or on the tablet in such a way that the surface of the particle(s) is, at most, partially in direct contact with the surface of the base composition surrounding this/these particles.Type: GrantFiled: April 4, 2001Date of Patent: May 4, 2004Assignee: Reckitt Benckiser N.V.Inventors: Guido Waschenbach, Ralf Wiedemann, Enric Carbonell, Ludwig Hertling, Natascha Wolf

Patent number: 6727213Abstract: A composition for use in a dishwasher is characterized by a base composition in the form of a tablet which becomes active substantially during the main wash cycle of the dishwasher. At least one separate zone in or on the tablet is provided with a substance that becomes active substantially during the rinse cycle of the dishwasher and with at least one substance that prevents lime scale build-up in the dishwasher and/or on the washed articles. The composition further includes agents that guarantee that at least the substance that becomes active substantially during the rinse cycle of the dishwasher is at least mainly released at the beginning of the rinse cycle at the earliest.Type: GrantFiled: June 28, 2002Date of Patent: April 27, 2004Assignee: Reckitt Benckiser N.V.Inventors: Guido Wäschenbach, Harald Magg, Richard Neergaard, Enric Carbonell, Ralf Wiedemann

Patent number: 6660704Abstract: Composition for use in a washing machine, characterized by a basic composition evolving its function essentially in the main washing cycle of the washing machine and in the form of a tablet, and at least one particle with at least one core comprising at least one substance evolving its function essentially in the rinsing cycles, and a covering substantially completely surrounding the core or cores comprising at least one compound, whose solubility increases with decreasing concentration of a specific ion in the surrounding medium, the at least one particle being placed in or on the tablet in such a way that the surface of the particle or particles is at the most in partial direct contact with the surface of the basic composition surrounding the same and the concentration of the specific ion in the local environment of the particle or particles is sufficiently high up to a substantially complete dissolving of the tablet in order to prevent a substantial dissolving of the covering or a substantial detachment ofType: GrantFiled: October 27, 2000Date of Patent: December 9, 2003Assignee: Reckitt Benckiser N.V.Inventors: Guido Waschenbach, Ralf Wiedemann, Enric Carbonell, Antonio Cordellina, Manuela Bosco, Giorgio Franzolin, Joan Clotet, Dora Zamuner, Paul W.
