Toothbrush

Abstract

A toothbrush having a toothbrush head with a top side at which cleaning elements for cleaning teeth are arranged. The cleaning elements form various zones of care or arrangements to meet specific cleaning and manufacturing requirements.

1 . 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 cross-section, 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 areas of compound tufts have 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. 
     
     
         2 . The toothbrush according to  claim 1 , 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. 
     
     
         3 . The toothbrush according to  claim 1 , 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. 
     
     
         4 . The toothbrush according to  claim 1 , wherein the first cleaning elements are of different lengths and the second cleaning elements are of the same lengths. 
     
     
         5 . The toothbrush according to  claim 1 , 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. 
     
     
         6 . The toothbrush according to  claim 1 , wherein the second cleaning elements have second bristle tufts with a circular tuft cross-section and/or elastomer cleaning elements. 
     
     
         7 . The toothbrush according to  claim 1 , 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. 
     
     
         8 . 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. 
     
     
         9 . 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. 
     
     
         10 . The toothbrush according to  claim 9 , 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. 
     
     
         11 . The toothbrush according to  claim 9 , 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. 
     
     
         12 . The toothbrush according to  claim 9 , 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. 
     
     
         13 . The toothbrush according to  claim 9 , wherein the elastomer cleaning elements are designed to be pin-shaped, in particular cylindrical, or that they taper conically towards the free ends. 
     
     
         14 . The toothbrush according to  claim 9 , wherein free ends of the elastomer cleaning elements are provided that are arranged to be adjacent to the bristle cleaning elements, and that the bristle cleaning elements project farther from the top side than the free ends of the elastomer cleaning elements, resulting in both cleaning elements together creating a trough-like cross-sectional area for receiving toothpaste. 
     
     
         15 . A toothbrush, in particular according to  claim 9 , having a toothbrush head with cleaning elements for cleaning teeth, which are grouped in various care zones in each case, having at least one pre-cleaning zone with longer cleaning elements relative to the cleaning elements in the cleaning zone, wherein the pre-cleaning zone is arranged at the free end of the toothbrush head, and having a polishing zone or massaging zone consisting of elastomer cleaning elements and a toothpaste receiving zone designed in a trough-like shape formed by cleaning elements. 
     
     
         16 . The toothbrush according to  claim 15 , wherein the free ends of the first, longer, cleaning elements and the second, shorter, 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 second cleaning elements. 
     
     
         17 . The toothbrush according to  claim 15 , wherein a further care zone is provided having interdental cleaning elements, which are designed to be longer than the cleaning elements immediately adjacent in the longitudinal direction of the toothbrush. 
     
     
         18 . The toothbrush according to  claim 17 , wherein the interdental cleaning elements are formed from bristle tufts that are arranged in a row transverse to the longitudinal center axis of the toothbrush. 
     
     
         19 . The toothbrush according to any one of  claim 15 , wherein the elastomer cleaning elements are designed to be shorter than bristle cleaning elements immediately adjacent thereto. 
     
     
         20 . The toothbrush according to any one of  claim 15 , wherein the cleaning elements are designed in such a way that the topography of the free ends of all cleaning elements, with the exception of the interdental cleaning elements, has two approximately concave depressions in the direction of the longitudinal center axis of the toothbrush from the free end of the head to the end of the head at the handle. 
     
     
         21 . The toothbrush according to  claim 20 , wherein the longer interdental cleaning elements protrude from each concave depression.
