  • Handheld toothbrush
    Patent number: 7146675
    Abstract: A handheld toothbrush with a brush head having a forward free end and a rearward portion. Provided at the forward free end of the brush head is at least one bristle tuft of a first set. Adjoining the first set in rearward direction is a second set of tufts comprised of several bristle tufts arranged serially on a ring and extending in the circumferential direction of the ring at an angle of inclination relative to the surface of the brush head. A third set of tufts adjoins the second set of bristle tufts in the direction towards the rearward portion.
