TOOTHBRUSH AND BRISTLE AND BRUSH HEAD FOR A TOOTHBRUSH |
摘要 |
The invention is directed to a bristle for a toothbrush, said bristle being comprised of a plastic monofilament, with the preferably cloverleaf-shaped bristle body having several longitudinal ribs arranged in star shape and projecting laterally from a core section of the bristle body. The invention is also directed to a brush head for an electric toothbrush having at least one bristle tuft with at least one such bristle as well as to an electric toothbrush having such a brush head. According to the invention, the bristle of the type initially referred to is configured to be self-fanning in such a manner that the cleaning forces acting on the bristles during normal brushing cause the bristle to split open at its free end. As a result, the need to use complex splitting methods and corresponding splitting machines in the manufacture of the toothbrush can be obviated. |
