Method for producing a brush, and brush

Abstract

A method of producing a brush as well as a brush ( 1 ), in particular a toothbrush, which has at least one bristle bundle ( 3 ) which includes at least one bristle filament having a curved and/or kinked profile.

1 . A method for producing a brush ( 1 ), comprising:
 proceeding from a non-deformed initial shape, permanently forming at least one bristle bundle ( 3 ) of the brush ( 1 ) such that at least one bristle filament of the bristle bundle ( 3 ) upon deformation has at least one of a curved or kinked profile.   
     
     
         2 . The method as claimed  claim 1 , further comprising:
 fastening the at least one bristle bundle ( 3 ) to a bristle carrier ( 4 ) of the brush ( 1 ), with the at least one bristle filament of the bristle bundle ( 3 ) having the permanently deformed at least one of the curved or kinked profile.   
     
     
         3 . The method as claimed in  claim 1 , wherein the at least one bristle bundle ( 3 ), proceeding from the non-deformed initial shape, is permanently formed such that the bristle bundle ( 3 ) at a free bundle end thereof has a cross section which is not rotationally symmetrical. 
     
     
         4 . The method as claimed in  claim 1 , wherein the at least one bristle bundle includes at least two of the bristle bundles ( 3 ), and the method further comprises unifying the at least two bristle bundles in a common bundle portion 
     
     
         5 . The method as claimed in  claim 1 , further comprising dividing the at least one bristle bundle ( 3 ) at a free bundle end thereof into at least two mutually separate bundle end portions. 
     
     
         6 . The method as claimed in  claim 1 , wherein the at least one bristle filament comprises bristle filaments, and the method further comprises displacing the bristle filaments of the at least one bristle bundle ( 3 ) for generating a clearance ( 7 ) in the bristle bundle ( 3 ). 
     
     
         7 . The method as claimed in  claim 1 , further comprising forming the at least one bristle bundle ( 3 ) such that said bristle bundle ( 3 ) has at least two bundle cross sections which in terms of an longitudinal axis of said bristle bundle ( 3 ) are axially spaced apart from one another and differ from one another in terms of at least one of a shape or size. 
     
     
         8 . The method as claimed in  claim 1 , further comprising imparting the at least one bristle bundle ( 3 ) with at least one of a helical shape, a conical shape, a frustoconical shape, a chalice-shape, or a spread-out shape. 
     
     
         9 . The method as claimed in  claim 1 , further comprising forming at least two of the bristle bundles ( 3 ) with a conjointly twisted shape. 
     
     
         10 . The method as claimed in  claim 1 , further comprising forming the at least one bristle bundle ( 3 ) at least one of (a) under the influence of heat or (b) with a shape-imparting tool. 
     
     
         11 . The method as claimed in  claim 1 , further comprising forming at least one said bristle bundle ( 3 ) for supporting another of the bristle bundles ( 3 ) such that said bristle bundle ( 3 ) bears on the other bristle bundle ( 3 ), or forming two of said bristle bundles ( 3 ) for supporting a third one of the bristle bundles ( 3 ), such that the two bristle bundles bear on the third bristle bundle ( 3 ). 
     
     
         12 . The method as claimed in  claim 1 , further comprising imparting at least one of the bristle bundles ( 3 ) with a cross section having at least one of an angular or polygonal internal geometry or an angular or polygonal external geometry. 
     
     
         13 . The method as claimed in  claim 1 , further comprising imparting at least one of the bristle bundles ( 3 ) with a cross section having at least one of a round or circular internal geometry or having a round or circular external geometry. 
     
     
         14 . A brush ( 1 ), comprising at least one of:
 (a) at least one bristle bundle ( 3 ) having at least one bristle filament having at least one of a curved or kinked profile, or   (b) at least one bristle bundle ( 3 ) which at a free bundle end thereof has a cross section which is not rotationally symmetrical.   
     
     
         15 . The brush ( 1 ) as claimed in  claim 14 , wherein the at least one bristle bundle ( 3 ) includes two of the bristle bundles that are unified in a common bundle portion, or the at least one bristle bundle ( 3 ) at a free bundle end thereof is divided into at least two mutually separate bundle end portions. 
     
     
         16 . The brush ( 1 ) as claimed in  claim 14 , wherein the at least one bristle filament includes bristle filaments, and the at least one bristle bundle ( 3 ) includes a clearance ( 7 ) generated by the bristle filaments of the bristle bundle ( 3 ) being at least one of displaced and permanently deformed. 
     
     
         17 . The brush ( 1 ) as claimed in  claim 14 , wherein at least one of (a) the at least one bristle bundle ( 3 ) in terms of the longitudinal axis thereof has two bundle cross sections which are axially spaced apart from one another and which differ from one another in terms of at least one of a shape or size, or (b) the at least one bristle bundle ( 3 ) has a helical shape, a conical shape, a frustoconical shape, a chalice-shape, or a spread-out shape. 
     
     
         18 . The brush ( 1 ) as claimed in  claim 14 , wherein the at least one bristle bundle includes at least two of the bristle bundles, and the at least two bristle bundles ( 3 ) are conjointly twisted. 
     
     
         19 . The brush ( 1 ) as claimed in  claim 14 , wherein the at least one bristle bundle ( 3 ) comprises at least one of (a) crimped bristle filaments, (b) undulated bristle filaments, (c) crimped and undulated bristle filaments, (d) bristle filaments of different material thickness, (e) bristle filaments from different materials, (f) bristle filaments with added grain, bristle filaments with an added antibacterial substance, or (g) bristle filaments with added grain and an added antibacterial substance. 
     
     
         20 . The brush ( 1 ) as claimed in  claim 14 , wherein the at least one bristle bundle ( 3 ) includes the free bundle end, and the free bundle end has a convex or concave end contour. 
     
     
         21 . The brush ( 1 ) as claimed in  claim 14 , wherein the at least one bristle bundle ( 3 ) includes a plurality of bristle bundles, and one of the bristle bundles bears on another of the bristle bundles ( 3 ) as a support, or two of the bristle bundles ( 3 ) bear on a third of the bristle bundles ( 3 ) as a support. 
     
     
         22 . The brush ( 1 ) as claimed in  claim 14 , wherein the at least one bristle bundle ( 3 ) has a cross section having at least one of an angular or polygonal internal geometry or at least one of an angular or polygonal external geometry. 
     
     
         23 . The brush ( 1 ) as claimed in  claim 14 , wherein the at least one bristle bundle ( 3 ) has a cross section having at least one of a round or circular internal geometry or a round or circular external geometry.
