Toothbrush has ring and flat surface on handle so it rests in stable position with bristles away from supporting surface

摘要

The toothbrush, made from a hard but lightweight plastic, consists of a head (6) with bristles (9) and a handle (17). Between the head and handle it has a circular collar (16), perpendicular or inclined relative to the lengthwise axis of the brush, and the handle has at least one flat surface (18), so that when the brush is laid on a horizontal support the bristles are raised above the surface of the support.
