Definitions
- the present invention relates to brush heads for toothbrushes in which a part of the tufts is inclined and a part of the tufts is vertical.
- Toothbrushes with a mixed stocking perpendicular to the bristle carrier upstanding tufts on the one hand and inclined, cross-shaped x-shaped tufts on the other hand, all bristles are cylindrical, are known from EP-A-O 885 573.
- the Applicant of the present application sells three toothbrushes of this type in Europe under the names Elmex Inter X, Elmex Inter X sensitive and Elmex Inter X junior. These toothbrushes are distinguished from a brush with exclusively vertical or exclusively x-shaped crossed tufts by a good cleaning performance both in the tooth surfaces and in the interdental spaces.
- toothbrushes with so-called “pointed” bristles are also known, with only pointed bristles being present in vertical tufts. Sharpened bristles are more flexible than conventional bristles and therefore allow a gentler cleaning of the tooth surfaces with less risk of injury.
- a brush head for a toothbrush which has a handle part, a head part and a bristle surface with bristle tufts inserted therein, wherein at least one of these tufts is perpendicular to the bristle surface and at least one of these tufts is inclined, characterized in that the inclined bristle tufts consist of cylindrical bristles and that at least a part of the vertically protruding tufts consist of sharpened bristles.
- Figure 1 shows how some of the sizes used in the context of the present invention are to be understood in relation to the inclined and pointed bristle tufts.
- FIG. 2 shows a preferred embodiment of the brush head according to the invention.
- FIG. 3 shows a preferred embodiment of the arrangement of the bushing holes on the bristle carrier, which is particularly suitable for the brush head according to FIG. _ O _
- FIG. 4 shows the measured values of the mesial / distal cleaning performance achieved with brush heads according to the invention.
- the brush heads according to the invention comprise, in addition to at least one vertically protruding tuft of sharpened bristles, one or more inclined tufts.
- inclined in the context of the present application means that an inclined tuft is inclined at an acute angle to an imaginary line perpendicular to the bristle face, this imaginary line passing through the center of the hole in the bristle carrier associated with said tuft.
- This acute angle may be about 1 to about 45 °, preferably about 1 ° to about 10 °, more preferably about 7 to about 9 °, and most preferably about 8 °.
- An inclined tuft can thus be inclined in the said acute angle about forward, backward or to one side.
- those tufts that are at the edge of the bristle carrier are projecting from the bristle carrier projecting at said acute angle outwards, allowing a better cleaning of the gums.
- skewed means that the tuft in question is skewed forward or backward, more preferably that all skewed tufts are skewed either forwardly or rearwardly.
- tilted means in the present ⁇ application that a forward slanted tuft seen in the longitudinal direction of the bristle carrier at the acute angle of the handle part is inclined away.
