Definitions

  • the present invention relates to a brush head for a toothbrush where the brush head has a plurality of bristles and where a first set of the bristles projects straight upright from the brush head body, and where a second set of the bristles forms an angle with the head body.
  • the toothbrush head mentioned above is characterised in that some of the bristles in the second set are arranged on the brush head as at least two concentric rings, thereby forming a third set of bristles.
  • the third bristle set is positioned at approximately the halfway point in the longitudinal direction of the brush head. At least some of the bristles in the first set, i.e., the vertically projecting set, are advantageously located in front of the third set, and some are also located behind the said third set. "In front of should be understood to mean the area at the free end of the brush head, whilst “behind” should be understood to mean the area of the brush head lying closest to the neck and handle of the toothbrush.
  • the bristles in the second set that are arranged in front of and behind the third set are positioned so that they slope away from the third set.
  • the bristles in the two bristle rings of the third set of bristles may be advantageous to allow the bristles in the two bristle rings of the third set of bristles to slope in the same direction along their respective rings.
  • the bristles in the outer ring preferably have a greater angle of inclination than the bristles in the inside ring. It would also be advantageous to allow there to be at least one straight upright projecting tuft of bristles in the centre of the third set.
  • Fig 1 shows the toothbrush head seen looking directly towards the head face that supports the bristles
  • Fig 2 shows the brush head seen from one side
  • Fig 3 is a perspective view of a brush head equipped with bristles
  • the brush head is indicated by the reference numeral 1
  • the brush head consists of a relatively rigid material 2 of, e g , plastic, and a plurality of bristles 3 projecting from respective holes 4 in the rigid part 2 of the brush head
  • a first set of bristles, indicated by the reference numeral 5 projects vertically from the head body 2, whilst a second set of bristles, indicated by the reference numeral 6, forms an angle with the head body 2
  • Some of the bristles in the second set are arranged on the head body 2 as at least two concentric rings 6' and 6"
  • the third set of bristles 6, 6' is arranged at approximately the halfway point in the longitudinal direction of the brush head It will also be seen from Fig 1 in particular, but also from Fig 3, that at least some of the straight upright projecting bristles 5 are located in front of the third set 6', 6" and some behind this set It will also be seen from Figs 1 and 3 in particular that the bristles in the second set that are arranged in front of
  • the present invention provides a brush head on a toothbrush which during clinical tests has been found to have improved brushing properties compared with known toothbrushes of the type mentioned in the introduction
  • the major advantage of the present invention over the known solutions is that a greater number of the bristles than usual will form a V-shape, irrespective of the brushing direction
