Toothbrush

Abstract

A toothbrush having a toothbrush head with a top side at which cleaning elements for cleaning teeth are arranged. The cleaning elements and the head can facilitate the removal of foam, plaque and undesired particles.

A toothbrush having a toothbrush head with a top side at which elements are arranged for cleaning teeth, with a bottom side that is arranged opposite to the top side and that connects the top side with the bottom side with lateral surfaces, wherein at least one lateral surface has a curvature, and wherein the toothbrush head has an elastomer component and a hard plastic component, wherein the surface of the lateral surface having the curvature is partly covered with the elastomer and partly with the hard component. 
     
     
         2 . The toothbrush according to  claim 1 , wherein lateral surfaces are arranged along the longitudinal side of the toothbrush head, which are convexly curved to the outside or provided with an outward bulge and are provide with a hard plastic component. 
     
     
         3 . The toothpaste according to  claim 1 , wherein the region of the lateral surfaces that is adjacent to the convex curvature, is provided with elastomer on both sides. 
     
     
         4 . The toothbrush according to any one of the preceding claims, wherein each lateral surface is designed to alternate hard plastic, elastomer, hard plastic, elastomer, and hard plastic. 
     
     
         5 . The toothbrush according to  claim 1 , wherein the lateral surfaces are provided partly with elastomer and partly with a hard plastic component over the entire height extending from the bottom side to the top side. 
     
     
         6 . The toothbrush according to  claim 1 , wherein the lateral surface has a cut-out near the surface relative to the hard plastic component, which is filled with the elastomer. 
     
     
         7 . The toothbrush according to  claim 1 , wherein an elastomer tongue scraper on the bottom side develops into a region with elastomer at the lateral surface and further into elongated massaging fingers made of the same elastomer. 
     
     
         8 . A toothbrush having a handle and a toothbrush head at whose top side first, second, and third cleaning elements are provided for cleaning teeth, wherein the first cleaning elements have first bristle tufts, which, as single tufts, each have a long and a short side and thus an approximately rectangular or oval base in crosssection, or, as compound tufts separated from one another, are arranged with their center points along a straight line each of a first bristle tuft each in such a way that enveloping area of compound tufts has first bristle tufts that have an approximately rectangular or oval base in cross-section, wherein a longitudinal center axis of the toothbrush proceeds from a free handle end to a free head end and a transverse axis is arranged perpendicular to the longitudinal center axis, wherein several first bristle tufts are arranged on the top side in such a way that their combined circumferential surface forms an approximately triangular, square, rhombic, or pentagonal base. 
     
     
         9 . The toothbrush according to  claim 8 , wherein the combined circumferential surface of the first bristle tufts forms a square or rhombic base, wherein two corners of the square or rhombus of the first cleaning elements are arranged along a longitudinal center axis of the toothbrush and the two additional corners of the square or rhombus of the first cleaning elements are arranged on an axis transverse to the longitudinal center axis. 
     
     
         10 . The toothbrush according to  claim 8 , wherein the first cleaning elements surround the second cleaning elements, and the first cleaning elements are designed to be longer than the second cleaning elements, resulting in a trough-like toothpaste receiving zone formed by the free ends of the second cleaning elements and the surrounding end areas of the first cleaning elements. 
     
     
         11 . The toothbrush according to  claim 8 , wherein the first cleaning elements are of different lengths and the second cleaning elements are of the same lengths. 
     
     
         12 . The toothbrush according to  claim 8 , wherein the compound bristle tufts of the first bristle tufts and the bristle tufts of the second and third cleaning elements each have circular cross sections, wherein immediately adjacent bristle tufts are arranged with the shortest lateral distance to one another; in the direction of the longitudinal center axis with a distant smaller than 0 mm and in the direction of the transverse axis with a distance of from 0 to 0.5 mm. 
     
     
         13 . The toothbrush according to  claim 8 , wherein the second cleaning elements have second bristle tufts with a circular tuft cross-section and/or elastomer cleaning elements. 
     
     
         14 . The toothbrush according to  claim 8 , wherein the first bristle tufts are designed to be longer than the second bristle tufts and/or that the first bristle tufts enclose the second bristle tufts or the elastomer cleaning elements. 
     
     
         15 . A toothbrush having a handle and a toothbrush head, at whose surface first, second, and third cleaning elements are provided for cleaning teeth, wherein the first cleaning elements surround the second cleaning elements, wherein the second cleaning elements are designed to be shorter than the first cleaning elements, wherein the free ends of the first cleaning elements and the second cleaning elements form a trough-like toothpaste receiving zone, and wherein the first cleaning elements form an approximately triangular, square, rhombic, or pentagonal enveloping area of the base enclosed therewith. 
     
     
         16 . A toothbrush having a toothbrush head with a top side having cleaning elements made of an elastomer for cleaning teeth, wherein a platform is arranged on the top side of the toothbrush head, that the elastomer cleaning elements are attached to the platform, and that the elastomer cleaning elements and the platform are made of the same elastomer. 
     
     
         17 . The toothbrush according to  claim 16 , wherein the platform has a square, rectangular, oval, or circular base and that an axis of symmetry of the platform base is arranged within the longitudinal center plane of the toothbrush. 
     
     
         18 . The toothbrush according to  claim 16 , wherein the platform extends away vertically from the top side between 10% to 90% of the total longitudinal extension of the platform having elastomer cleaning elements. 
     
     
         19 . The toothbrush according to  claim 16 , wherein the top side of the platform at which the elastomer cleaning elements are arranged is designed to be flat and parallel to the top side of the toothbrush head or designed to be spherically arched. 
     
     
         20 . The toothbrush according to  claim 16 , wherein the elastomer cleaning elements are designed to be pin-shaped, in particular cylindrical, or that they taper conically towards the free ends.
