  • Patent number: 8020238
    Abstract: 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.

  • Patent number: 6848141
    Abstract: 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.

  • Patent number: 6643886
    Abstract: 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.

  • Publication number: 20030140435
    Abstract: 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.

  • Patent number: 6367112
    Abstract: The present invention relates to a toothbrush having a handle formed of interlocking opposed S-curved sections, the first being relatively rigid and the second relatively resiliently flexible, the opposed S-curved sections forming a generally elongated FIG. 8, having a transverse aperture within each segment of the FIG. 8, such that during brushing the user can manipulate the relatively rigid and resiliently flexible section to position the bristle bearing face of the toothbrush to conform to the arcuate configuration of the dentiture.
