Patent number: 5446940Abstract: A toothbrush whose tufts comprise three distinct groups of rows, with each row oriented transversely to the longitudinal axis of the head. The tufts of the first group are the shortest. The endmost tufts on each row of the second kind tilt laterally outwardly by about 12 degrees. The tufts of the third group are nearest the end of the head farthest from the handle and diverge from each other. In one embodiment, each tuft of the third kind tilts laterally at an angle of about 30 degrees and forwardly at about 14 degrees. In a first embodiment, each row of the first group comprises a single, wide tuft. In a second embodiment, each row of the first group has a plurality of laterally spaced round tufts. In a third embodiment, each row of the first group comprises a plurality of laterally spaced quadrangular tufts. All of the tufts may also be considered as defining four functional groups of tufts, with each of these four groups performing a specific function during brushing.Type: GrantFiled: June 8, 1994Date of Patent: September 5, 1995Assignee: Colgate-Palmolive CompanyInventors: John P.
