<p>A convex base plate made of flexible plastic or rubber, with wire or plastic bristles fits into the edge of a frame on the front of the main part (1) of the brush. The frame consists of at least two injection moulded parts fitted together with the base plate in between. The two parts can be fitted together via serrations. When placed together, the two injection moulded parts rest against two stop pieces. Running down the back of the brush is a narrow surface (5) extending to the handle (2) which is of roughly rectangular cross-section, and tapers towards its free end. Between the main brush part (1) and the handle (2) are ridged (4) cavities for gripping.</p> |
