  • Toothbrush provided with an articulated arm bearing a protective cap
    Patent number: 7310848
    Abstract: A toothbrush having a head placed at a front longitudinal end of a handle made overall as a single piece. The head has flexible brushing elements on its upper surface. The toothbrush is equipped with an arm articulated at one end, and provided at the opposite free end with a protective cover for the brushing elements. The general thickness of the arm gradually increases from its articulation end to the cover so as to form a profile projecting from a longitudinal surface of the rear portion of the handle, by virtue of which the gripping surface of the handle is increased. The articulation of the arm on the handle is designed to allow it to describe at least two different rotations about two substantially orthogonal geometric axes.
