Toothbrush which is self-rotating through the action of the movement imparted to the handle during brushing

摘要

The rotational movement favourably required is obtained because the handle 1 and the support of the bristles forming the brush 2 are joined with the aid of a shaft 3. According to other embodiments, this rotational movement may result from the interpenetration of the bristle support 2 and of the handle 1 via internal and external complementary circular perimeters of the said elements. <IMAGE>
