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. Gatzemeyer

Patent number: 6848141Abstract: An electric toothbrush brush section and method of use thereof is disclosed, the brush section having a generally disk shaped bristle carrier from which extend one or more bristle bearing fingers of varying length and width, which fingers provide increased contact area between bristles and oral gingival tissue for enhanced massaging thereof.Type: GrantFiled: June 8, 2001Date of Patent: February 1, 2005Assignee: Colgate-Palmolive CompanyInventors: Eyal Eliav, Kyoungeun Ahn, John J. Gatzemeyer

Patent number: 6643886Abstract: The present invention relates to an enhanced cleaning toothbrush bristle pattern, wherein two rows of taller bristle tufts transversely divide the toothbrush head into three sections, the bristle tufts within each section having a trim pattern which in profile is convex in relation to the toothbrush face; wherein the two rows of taller bristle tufts penetrate between teeth, while the curved trim profile of each section provides for good conformity to the curved tooth surfaces and for an improved sweeping action.Type: GrantFiled: February 20, 2001Date of Patent: November 11, 2003Assignee: Colgate Palmolive CompanyInventors: Robert Moskovich, Kenneth Waguespack, Eyal Eliav, Eric Chan, Kyoungeun Ahn

Publication number: 20030140435Abstract: A toothbrush head containing a first tuft block mounted for oscillating about a centrally located axis and an elongated second tuft block mounted for rotational movement about an axis eccentric to its center point. One of the tuft blocks has a recess for receiving an extension of the other tuft block to create a drive connection between the two tuft blocks, such that when one of the tuft blocks is driven by a drive structure the rotational movement of that tuft block causes the other tuft block to oscillate.Type: ApplicationFiled: April 9, 2002Publication date: July 31, 2003Inventors: Eyal Eliav, Kyoungeun Ahn, John J. Gatzemeyer, Eduardo Jimenez
