Patent number: 8032964Abstract: A brush section for use with an electric toothbrush includes a relatively large brush head portion having a generally rectangular shape, although oblong, elliptical and other such shapes having a length to width aspect ration greater than 1 may be employed. The brush head portion is secured to a shaft portion of the brush section that may be configured to couple to a handle section. The handle section may include an electric drive including drive shaft, and the drive shaft may couple to the brush head via a coupling member positioned within the shaft portion. The electric drive may impart a rotary, oscillating rotary-oscillating or other suitable drive motion to the drive shaft that is, in turn, imparted upon the brush head by virtue of the coupling member.Type: GrantFiled: January 31, 2008Date of Patent: October 11, 2011Assignee: The Gillette CompanyInventors: Mark Edward Farrell, Christopher Charles Blain, Phillip Maurice Braun

Patent number: 8020238Abstract: A powered toothbrush refill head combines a typical round oscillating or primary tuft block which oscillates in a rotational manner with a secondary tuft block. The secondary tuft block may be oscillated in a rotational manner or may oscillate linearly back and forth in the same direction as the handle of the toothbrush. The secondary tuft block could be in the form of a pair of side by side plates mounted on the head adjacent to the round oscillating block. The invention could also be practice where the secondary tuft block is in the form of a plurality of sets of rows of bristles mounted for back and forth movement in a direction perpendicular to the handle.Type: GrantFiled: August 19, 2008Date of Patent: September 20, 2011Assignee: Colgate-Palmolive CompanyInventors: Eyal Eliav, Kyoungeun Ahn, John J.

Patent number: 8011057Abstract: There are provided a device and a method for cleaning teeth. The device comprises a brush, a shaft connected to the brush, a neck surrounding the shaft along a substantial portion of the length of the shaft, and a controller coupled to the shaft at the end of the shaft opposite the brush, the controller being mounted at the base of the neck so as to be movable between a first position that extends the brush away from the neck, and a second position that retracts the brush towards the neck. The method comprises inserting, between adjacent teeth, a device having a brush, a controller and a handle, the controller for effecting movement of the brush in a direction generally perpendicular to the handle, and keeping the handle generally stationary while moving the controller up and down to move the brush along front-to-back and back-to-front paths between the adjacent teeth. Moving the controller may occur via pressure from a user's finger, or via force from a motor in the device.Type: GrantFiled: July 26, 2007Date of Patent: September 6, 2011Inventor: Richard Nejat

Patent number: 7962988Abstract: A powered toothbrush includes a handle having a neck. A head is mounted to the neck and has a first surface and an opposed second surface. At least one fixed tuft block is mounted to the head in a fixed orientation and has a plurality of tooth cleaning elements extending outwardly away from the first surface. A movable tuft block is flexibly connected to each fixed tuft block and has a plurality of tooth cleaning elements extending outwardly away from the first surface. A drive assembly is operably connected to the movable tuft block to move the movable tuft block with respect to each fixed tuft block.Type: GrantFiled: June 30, 2010Date of Patent: June 21, 2011Assignee: Colgate-Palmolive CompanyInventor: Alan Sorrentino

Patent number: 7954193Abstract: An oral hygiene device having two toothbrushes connected or connectable to the end of a handle, the one or more toothbrushes providing a desirable fit about the teeth and/or gums and/or providing a desirable brushing action. An oral hygiene device hereof may provide for mechanically providing the brushing movements of the professionally recommended manual tooth-brushing method known as the “Bass” or “Modified Bass” technique to thus reduce or eliminate the element of human error associated with the brushing of a user's teeth and gums.Type: GrantFiled: December 14, 2010Date of Patent: June 7, 2011Assignee: CRA Labs, Inc.Inventors: Kenneth Hegemann, Rob Hegemann, Jay Hegemann, Tiana L. K. Buschmann

Patent number: 7954192Abstract: The head of a toothbrush includes a first tuft block having bristles and a second tuft block having bristles. The first and second tuft blocks are mounted for counter-rotational or counter-rotational oscillating movement in a direction parallel to the outer surface of the head. The toothbrush head also includes a third section having bristles extending outwardly from the head to provide an extended field of bristles to support an elongated ribbon of toothpaste and for enhanced cleaning.Type: GrantFiled: May 27, 2009Date of Patent: June 7, 2011Assignee: Colgate-Palmolive CompanyInventors: John J. Gatzemeyer, Thomas Mintel

Publication number: 20110083289Abstract: A domestic appliance includes a head divided into a first rotatable member and a second rotatable member, and a drive mechanism for rotating the head about a first axis while simultaneously rotating the first rotatable member about a second axis and the second rotatable member about a third axis. Each of the second axis and the third axis is angled to and preferably intersects the first axis. When viewed in a direction extending along the second axis towards the first axis, the drive mechanism rotates the first rotatable member about the second axis in a first angular direction and the second rotatable member about the third axis in a second angular direction opposite to the first angular direction.Type: ApplicationFiled: October 8, 2009Publication date: April 14, 2011Applicant: Dyson Technology LimitedInventors: Emma Jane Heatley-Adams, Paul Anthony Denney, Peter David Gammack, James Dyson, Jeremy William Crouch

Patent number: 7900309Abstract: The head of a powered toothbrush includes a first tuft block mounted for rotational oscillation about an axis generally perpendicular to the outer surface of the head, and a second tuft block having fixed bristles or bristles independently movable by being mounted on an elastomeric base. The second tuft block oscillates perpendicular to a longitudinal axis of the head and in an in and out direction perpendicular to the outer surface of the head. A third stationary block may also be mounted on the head of the powered toothbrush. The bristles on the first, second, and third tuft blocks may be of various lengths, colors and stiffness, and may be mounted perpendicularly to or at an angle to the outer surface of the head.Type: GrantFiled: August 26, 2008Date of Patent: March 8, 2011Assignee: Colgate-Palmolive CompanyInventors: John J.
