Abstract

Brush for cleaning teeth, comprising a support handle and a bristle-carrying head joined via a flexible hinge, the axis of which is arranged in a plane essentially parallel to the plane of the head and is oriented perpendicularly with respect to the longitudinal axis of the brush. This hinge consists of an assembly of two flexible, thin, side bridge-pieces formed as one piece with the handle and the head and constituting the main element for joining and connecting together the latter, and of a mass of elastomeric filling material injected into the space between said bridge-pieces. The handle, the head and the bridge-pieces are made of a relatively rigid material (for example polypropylene) having a chemical affinity with the softer material (for example a polyolefin-based elastomer) constituting the filling mass. The hardness of this mass determines the rigidity of the hinge, depending on the intended use of the brush (soft, medium or hard; for adults or for children). <IMAGE>
