Description

  • The The invention relates to a toothbrush head consisting of three on a bristle insert surface of the toothbrush head fixed bristle tuft groups, wherein the arranged at the free end of the toothbrush head bristle tufts group tufts composed circularly around a central bristle tuft at it the second bristle tufts group, the x-shaped design is, connects and the third bristle tufts group adjoining the bristle tufts are bevelled and a bunch of bristle tufts form the second bristle tufts group out in the air drops.
  • The Company WYBERT GmbH introduces a toothbrush, which consists of three on a bristle insert surface of the toothbrush head fixed bristle tufts groups consists, wherein arranged at the free end of the toothbrush head bristle tufts group from bristle tufts consists, which are attached circularly around a central bristle tufts. The upstanding end of this bristle tufts group is to a on the bristle insert surface subsequent second bristle tufts group sloping downwards. This second bristle tufts group is X-shaped educated. Below is on the bristle insert surface the third bristle tufts group arranged to the x-shaped Tufts Group sloping downwards is.
  • The DE 197 05 104 A1 shows a toothbrush head with two groups of bristle tufts on a bristle tuft insert surface. In this case, protruding from a circular bristle tufts group at the free end of the toothbrush head, the central bristle tufts. In the second bristle tuft group adjoining it, the tufts attached to the side of the toothbrush head edge project beyond the other tufts of the bristle tufts.
  • From the DE 44 09 395 C1 For example, a toothbrush head having tufts of bristles protruding at right angles is known, wherein a first group of bristle tufts arranged at the free end of the toothbrush head has a rounded bristle tuft group of tufts of bristles. The bristle tufts of the second group are arranged in transverse rows, which extend at right angles to the longitudinal axis of the toothbrush head. The height of these bristle tufts alternately changes between two different height levels.
  • The DE 34 33 763 C1 shows a toothbrush head with extending in the longitudinal direction of the brush head, juxtaposed inner and outer rows of bristles, wherein the bristle length of the outer rows of bristles is greater than that of the inner rows of bristles. The bristle tips of the outer bristle rows are rounded and those of the inner bristle rows are mushroom-shaped.
  • From the large number of different toothbrush heads another group is known which has tufts of different hardness. An example of this is the DE 35 24 586 A1 , Here, the toothbrush head consists mainly of bristle tufts of the same hardness, wherein a bristle row is arranged with respect to the remaining rows of bristles harder bristle tufts in the transverse direction to the longitudinal axis of the toothbrush head.
  • The DE 299 16 640 U1 relates to a brush, in particular a toothbrush, with a handle handle and a bristle filament bearing bristle carrier which is movably mounted on the handle handle and arranged in the axial extension of the same. In this case, the bristle carrier is connected to the front end of a bristle bundle bearing bust head exclusively with the interposition of a soft elastic component.
  • From the EP 0 885 573 A1 goes out a brush head for a toothbrush, which has a bristle carrier, in which bristles summarized to bristle tufts are anchored. The bristle tufts are arranged side by side in a plurality of transverse rows aligned at right angles to the longitudinal direction of the toothbrush. In the longitudinal direction of the toothbrush, at least one group of transverse rows formed from bristle tufts substantially perpendicular to the bristle carrier and at least one pair of transverse rows formed from bristle tufts inclined longitudinally relative to the bristle carrier are arranged one behind the other. The longitudinally inclined bristle tufts of one of these transverse rows are inclined backwards such that the bristle tufts of these two transverse rows intersect each other and form an X-shape in pairs.
  • The toothbrush development is subject to a permanent Progress aimed at optimal tooth cleaning. there should occlusal surface, Tooth flanks and interdental areas thoroughly and simply cleaned become. However, there is the problem that the brush tuft insert surface a rigid surface which is followed by a hard toothbrush head edge. Consequently there is a risk of injury to the gums and the palate the dental care.
  • The object of the invention is a toothbrush head, consisting of three on a bristle insert surface of the toothbrush head fixed bristle tufts groups, wherein the arranged at the free end of the toothbrush head bristle tufts group consists of bristle tufts, the are circularly mounted around a central bristle tufts, it is the second bristle tufts group, which is formed in an X-shape, and adjoining the third bristle tufts group adjoining the bristle tufts are tapered and thereby form a bristle tufts group, which drops to the second bristle tufts group in height To develop, with which the risk of injury of the gums and the palate are reduced.
  • According to the invention Task solved by that the central bristle tufts protrudes upward, that between the first bristle tufts group and the second bristle tufts group concentrically to the first group of bristle tufts a bunch of bristle tufts is arranged, from one toothbrush edge to the other toothbrush edge enough that around the circular bristle tufts group and each other on the back side of the toothbrush head around a circular core depending on a bead-shaped elastic limit with her bottom in the toothbrush head is firmly embedded, and adhere to the bulbous elastic limit of the core tangentially opposite in the direction of the two edge sides of the toothbrush head depending on a bead-shaped rubber-elastic Strip connects, in the area of the second group of bristle tufts on the toothbrush edge pulled up. It is advantageous if the bead-shaped rubber-elastic Limiting the circular tuft group a top edge at the free end of the toothbrush head forms. It is useful if the bulbous rubber-elastic boundaries and strips of a deformable polymer material consist. The bristle tufts groups can from bristle tufts different bristle diameter exist, but it can also the bristle tufts even have different bristle diameters. This toothbrush head has the particular advantage that the circular bristle tufts group at the free end of the toothbrush head by the around the circular bristle tufts group and each other on the back side of the toothbrush head around a circular core attached bead-shaped rubber elastic boundaries a certain elasticity has. Furthermore, the rubber elastic limit on the free act End of the toothbrush head, the rubber-elastic boundary around the core and the two tangential Gentle from the circular core running elastic strips on the palate.
  • The The invention will be explained in more detail with reference to schematic drawings. It demonstrate:
  • 1 a top view of the toothbrush head,
  • 2 a side view of a toothbrush head and
  • 3 a top view of the toothbrush head back.
  • The illustrated toothbrush head 1 goes in the area of the connection area 2 into the stem of a manual toothbrush. How out 2 to recognize are on a bristle insert surface 3 of the toothbrush head 1 three bristle tufts groups 4 . 5 and 6 arranged. The bristle tufts group 4 is at the free end of the toothbrush head 1 attached, being around a central protruding bristle tufts 7 tufts 8th are arranged. To this circularly arranged bristle tufts group 4 is a bead-shaped elastic limit 9 attached in the bristle insert area 3 is firmly embedded with the bottom. This limit 9 covers the bristle insert surface 3 at the free end of the toothbrush head 1 circular from. Concentric to this limit 9 closes on the handle side a number of bristle tufts 10 from one toothbrush head side to the other toothbrush head side on the bristle insert surface 3 runs. The bristle tufts 10 and the bristle tufts 8th are the same height and perpendicular to the toothbrush head 1 arranged. At this bristle tufts 10 the bristle tufts group closes 5 on, their bristle tufts 11 X-shaped from the bristle insert surface 3 are directed upwards and the bristle tufts 8th and 10 overtop. The bristle tufts 11 the bristle tufts group 5 For example, are inclined from the vertical by 8 degrees x-shaped to each other. Next to this group of bristle tufts 5 is the handle side, the third bristle tufts group 6 of the toothbrush head 1 arranged. The bristle tufts 12 the bristle tufts group 6 are beveled at the top, with the bristle tufts group 6 to the bristle tufts group 5 going down in height. On the back side 13 of the toothbrush head 1 is mutually from the circular bristle tufts group 4 around a circular core 14 a bead-shaped elastic limit 15 attached, with the bottom firmly in the back 13 of the toothbrush head 1 is embedded. To the bulge-shaped rubber-elastic, circular trained boundary 15 closes tangentially opposite in the direction of the two edge sides of the toothbrush head 1 each a bead-shaped rubber elastic strip 16 in the area of the second group of bristle tufts 5 at the toothbrush edge 17 pulled up and partially covered. The particular advantage is that the two bulbous rubber-elastic, circular shaped boundaries 9 and 15 in the area of the circular bristle tufts group 4 in the toothbrush head 1 form an elastic zone. This causes the cleaning process, a wobbling, oscillating proper motion of the circular bristle tufts group 4 he is witnessed. The on the back of the toothbrush head 1 attached bead-shaped elastic strips and the limit 15 as well as the limit 9 at the free end of the bristle insert surface 3 act in the oral area as rubber-elastic damper. The bristle tufts groups 4 . 5 or 6 can consist of bristle tufts of different bristle diameters, but it can also be the bristle tufts 8th . 10 . 11 or 12 even have different bristle diameters. For optical design, any group of bristle tufts 4 . 5 or 6 or the row of bristle tufts 10 or the central bristle tufts 7 be different color.
