Benefits of technology

[0008]A primary object of the present invention is to present a toothbrush shaft that enables polishing of the teeth of the user in an efficient but light way.
[0009]A further object of the present invention is that the polishing function is limited to the teeth of the user, i.e. irritation of the gums is avoided.

Problems solved by technology

In connection with polishing means made out of rubber it is a general disadvantage that the polishing effect of such polishing means is not too good.
In connection with polishing of the teeth by rubber material it is common that one pushes too hard and with bristle straws located beside the rubber profile the pressure on the gums will be too hard.
This will eventually result in contracted gum and shooting / icing pain in the neck of the teeth.
However, there is a risk that the surrounding, longer, more spaced bristle hurts the gums if the polishing is effective.

Embodiment Construction

[0015]The toothbrush shown in FIG. 1 comprises a shaft 1 and a brush head 3, said shaft 1 and brush head 3 being integral. The brush head 3 comprises bristle straws, preferably in the shape of a number of bristle bundles 5 that in a known way are fastened to the brush head 3.

[0016]On the side of the brush head 3 that faces away from the bristle bundles 5 the brush head 3 is equipped with a polishing means 7 that comprises a cup shaped portion 9 and a fastening portion 10, by which the cup shaped portion 9 detachably may be fastened to the brush head 3. A waist 8 connects the cup shaped portion 9 with the fastening portion 10. The cup shaped portion 97 the waist 8 and the fastening portion 10 are manufactured from a flexible material, e.g. plastic. As is evident from FIG. 1 the fastening portion 10 is equipped with barbs 11 that are intended to cooperate with a cavity 12 of the brush head 3. The cavity 12 has a hole 13 that has a smaller across dimension than the cavity 12. This enab...
