Patent number: 11425987Abstract: A brush head for an electrically driven toothbrush is provided herein. The brush head includes a holding part connected to a carrier part, at least one bristle bundle formed by bristle filaments, and a resiliently soft cleaning element. The carrier part includes passage bores, through which the bristle bundle and resiliently soft cleaning element project, and each is fixed to the carrier part by way of a thickened portion formed by a filament material or a resiliently elastic material, respectively. A method of producing a brush head is also provided, including preparing the carrier part as a separate component with passage bores, fixing the bristle bundle and the resiliently clastic cleaning element to the carrier part with a thickened portion provided on the bristle bundle and the resiliently elastic cleaning element, respectively, and connecting the carrier part to the holding part.Type: GrantFiled: September 20, 2017Date of Patent: August 30, 2022Inventors: Erwin Buchholz, Berthold Meyer, Eric Schmidt

Patent number: 7086116Abstract: A dental cleaning implement such as a toothbrush, having longitudinally disposed first and second parts flexibly joined together. Between the first and second parts is a rotatable member such that when the implement bends the first parts adjacent to the member bear upon the member. The rotatable member has circumferentially disposed relatively softer and harder regions, so that as the member is rotated the parts can be caused to bear compressibly upon selected softer or harder regions.Type: GrantFiled: November 30, 2000Date of Patent: August 8, 2006Assignee: GlaxoSmithKline Consumer Healthcare GmbH & Co. KGInventors: Gerd Broecker, Matthias Georgi, Berthold Meyer, Wolf-Dieter Müller

Patent number: 6990706Abstract: A toothbrush having a head which carries a dental cleaning tool, and a grip handle, the head and handle being disposed along a longitudinal head-handle axis, the toothbrush having a resiliently flexible structure which can resiliently bend under the action of toothbrushing pressure and having adjustment means comprising a longitudinally moveable stiffening member which can be moved longitudinally into greater or lesser engagement with the resiliently flexible structure.Type: GrantFiled: November 30, 2000Date of Patent: January 31, 2006Assignees: GlaxoSmithKline Consumer Healthcare GmbH & Co KG, M&C Schiffer GmbHInventors: Gerd Broecker, Matthias Georgi, Berthold Meyer, Wolf-Dieter Müller

Patent number: 6919038Abstract: The present invention relates to a method of producing thick-walled brushes, in particular toothbrushes, with a grip piece and a brush head supporting bristle filaments. In order to increase the productivity, the method mentioned at the start is further developed by the present invention in that a core produced in a first injection molding cycle is coated with a plastic component in at least one subsequent injection molding cycle so as to form a multi-layered grip piece.Type: GrantFiled: January 17, 2003Date of Patent: July 19, 2005Assignee: M + C Schiffer GmbHInventors: Berthold Meyer, Andreas Walgenbach, Armin Seifert

Patent number: 6695414Abstract: The present invention relates to a method of manufacturing a brush head comprising a brush head body carrying bristle bundles, in particular for tooth brushes, by way of injection molding, in which a first plastic component is injected into a first mold cavity for forming a bristle carrier, and ends of bristle filaments projecting into the first mold cavity are encompassed by the first plastic component. In order to guarantee a complete filling of the mold and a favorable reproduction of the mold cavity geometry, but to avoid at the same time a penetration of plastic mass into ducts in which the bristle filaments are held, it is suggested by the present invention that the bristle carrier manufactured during the first step is relocated into another mold cavity, which is larger than the bristle carrier, and which is filled with a hard component.Type: GrantFiled: December 21, 2000Date of Patent: February 24, 2004Assignee: M + C Schiffer GmbHInventors: Berthold Meyer, Gerd Broecker

Patent number: 5454626Abstract: A method for configuring the use ends of the bristles of at least one bristle bundle in the fabrication of bristle products, including cutting the bristle bundle to a predetermined dimension and inserting it into the channel in a carrier, and bringing the use ends into a contact with a surface of a configuration plate having a configuration corresponding to the configuration of the use ends of the bristles of the bristle bundle, under gas pressure acting on bristle ends which are opposite to use ends.Type: GrantFiled: May 25, 1994Date of Patent: October 3, 1995Assignee: M + C Schiffer GmbHInventors: Carl Schiffer, Berthold Meyer

Patent number: 5054154Abstract: A toothbrush formed of a handle, a neck and a bristle head. In order to allow the bristle head to move out of the way in the event of excessive brushing pressure being applied during toothbrushing, an elastic segment is provided between the handle and the bristle head. Injury to the gums, damage to the teeth and possibly to the tooth-holding means can be averted by the elastic flexure of the bristle head. The elastic segment is formed by one or more clearances, slots or slits at least partially filled with elastic polymeric/copolymeric plastic material.Type: GrantFiled: October 17, 1989Date of Patent: October 8, 1991Assignee: M & C Schiffer GmbHInventors: Carl Schiffer, Berthold Meyer
