FIELD: items of personal and house use. ^ SUBSTANCE: tooth-brush contains a handle, head and at least one stock connected with it. The stock contains the top and bottom surfaces and a set of apertures located therebetween. Locks of bristle fibres go through the apertures, and the bottom ends of fibres are fused to form bristle coating covering at least partially the bottom surface. The bottom surface of the stock is located on distance from the head, and there is a cavity between the stock and the surface. The stock is made from firm and soft plastic materials and capable of partial elastic deformation against the head so that to take the form differing from the plane when using it. There are three variants of the tooth-brush; in the first one the stock is connected to the head on separate sites, in the second one the head has lateral dredging for access to a cavity under the stock and in the third one, the head has, at least, two stocks. A method for manufacturing a tooth-brush is also described. ^ EFFECT: high quality and effectiveness of teeth cleaning. ^ 29 cl, 40 dwg |
