Publication number: 20150257520Abstract: A head for an oral care implement has a mounting surface and at least one tuft mounted thereon. The tuft has a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis. The tuft comprises a plurality of substantially cylindrical filaments. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. The cross-sectional area of an individual filament has a substantially non-circular shape. The plurality of filaments is arranged such that the cross-sectional area of the tuft has a scaled-up shape of the individual filament's cross-sectional area.Type: ApplicationFiled: March 11, 2015Publication date: September 17, 2015Inventors: Ulrich STOERKEL, Simone BERTRAND, Martis HUEBNER, Andreas BIRK, Franziska SCHMID, Alexander HILSCHER, Heidrun SCHMELCHER, Jochen GANNINGER, Jochen KAWERAU, Uwe JUNGNICKEL, Benedikt HElL, Christian MANDL, Eva KAISER, Kathi BALLMAIER, Christine HIELSCHER, Britta STOCKINGER

Publication number: 20150130259Abstract: A process for creating multiple tufts for a tufted article comprises directing the initial filament bundle into a first channel, causing the bundle to move through the first channel while splitting the bundle into a plurality of tufts according to a predetermined pattern, and directing the plurality of tufts into the plurality of second channels such that each of the plurality of tufts has its own second channel. An apparatus comprises a first plate having a first channel for receiving a filament bundle, a splitting element for separating the bundle into the plurality of individual tufts, a second plate having a plurality of second channels for receiving the plurality of tufts, and a driving means for moving the filaments in the channels.Type: ApplicationFiled: November 8, 2013Publication date: May 14, 2015Applicant: The Procter & Gamble CompanyInventor: Andreas BIRK

Patent number: 8915552Abstract: A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements, such as bristle tufts may be fused by heat and may be placed in a mold cavity to be over-molded.Type: GrantFiled: April 29, 2014Date of Patent: December 23, 2014Assignee: Braun GmbHInventors: Andreas Birk, Lars Foerster, Ulrich Pfeifer, Klaus Amsel, Guenther Alschweig

Publication number: 20140352091Abstract: A toothbrush comprises a head, a neck portion and a handle, wherein the neck portion and the handle portion are connected to one another via a coupling element. The connection is constructed as an inseparable connection, i.e., after being combined once, the neck portion and the handle cannot be separated without the brush being destroyed by such separation. A method for producing such a toothbrush may comprise the following steps: providing a head, a neck portion, a handle, and a coupling element, and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed.Type: ApplicationFiled: May 8, 2014Publication date: December 4, 2014Applicant: Braun GmbHInventors: Andreas BRESSELSCHMIDT, Andreas BIRK, Holger SCHULZ, Wolfgang STEGMANN, Jochen GANNINGER, Michael JÖST, Karl HERZOG, Andreas REUSCHENBACH

Publication number: 20140352093Abstract: A method for producing a toothbrush comprises providing a head, a neck portion, and a handle; providing a coupling element; and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed. The individual parts of the toothbrush to be formed can be produced in parallel or successively, wherein some of the parts can be produced by injection molding. A toothbrush formed by the method comprises a head, a neck portion, and a handle; these elements can be produced as building blocks separately and may be connected to one another via a coupling element to form an inseparable connection.Type: ApplicationFiled: May 29, 2014Publication date: December 4, 2014Applicant: The Gillette CompanyInventors: Andreas BRESSELSCHMIDT, Andreas BIRK, Holger SCHULZ, Wolfgang STEGMANN, Jochen GANNINGER, Michael Jõst, Karl HERZOG, Andreas REUSCHENBACH

Patent number: 8845034Abstract: A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements may be placed successively or simultaneously in different mold cavities and may be over-molded using different plastic materials from which injection-molding sections of the bristle carrier are formed in the process. In doing so, a first cleaning element is over-molded in a first mold cavity using a first plastic material, while a second cleaning element is over-molded in a second mold cavity using a second plastic material.Type: GrantFiled: June 14, 2012Date of Patent: September 30, 2014Assignee: The Braun GmbHInventors: Andreas Birk, Lars Foerster, Ulrich Pfeifer, Klaus Amsel, Guenther Alschweig

Patent number: 8739351Abstract: A toothbrush having a handle, a head with oral care elements and a neck connecting the head with the handle is described. The toothbrush has a base structure of the handle, and the neck and the head are formed by a hard plastic component. Said basic structure of the handle is covered, at least in part, by a first soft plastic component. Said head including a second soft plastic component and said neck including a through-opening, wherein at least one section of a boundary wall of the opening is provided with an elastic muscle.Type: GrantFiled: September 15, 2011Date of Patent: June 3, 2014Assignee: Braun GmbHInventors: Bjoern Kling, Andreas Birk
