Abstract

In a mascara brush comprising a multiplicity of bristles fixed between two helically twisted wire segments, with bristles or tufts of bristles with varying radial lengths extending from the wire core formed by the helically twisted wires, provision is made for the tips of tie shorter bristles to be located essentially on a nearly rotation-symmetrical, especially cylindrical, inner envelope.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A mascara brush comprising a multiplicity of bristles fixed between two helically twisted wire segments, with bristles or tufts of bristles with varying radial lengths extending from the wire core formed by the helically twisted wires, wherein the tips of the shorter bristles ( 14 ) are essentially located on a nearly rotation-symmetrical, especially cylinder-shaped, inner envelope ( 18 ).  
     
     
         2 . A mascara brush according to    claim 1   , wherein the tips of the longer bristles ( 13 ) are located on a rotation-symmetrical, especially cylinder-shaped, outer envelope ( 17 ).  
     
     
         3 . A mascara brush according to    claim 2   , wherein the outer envelope ( 17 ) of the longer bristles conically narrows towards the tip.  
     
     
         4 . A mascara brush according to    claim 3   , wherein the outer bristles ( 13 ) are trimmed in such a way that the envelope ( 17 ) of the Ned sections conically narrows towards The envelope ( 18 ) of the shorter bristles ( 14 ).  
     
     
         5 . A mascara brush according to    claim 1   , wherein the shorter and longer bristles ( 14 ,  13 ) extend away from the wire core ( 12 ), flaring outward in a tuft-like manner, with the outer tuft boundaries ( 20 ) of the shorter bristles ( 14 ) extending at approximately mid-height to the outer tuft boundaries ( 20 ) of the bristle tufts ( 15 ) of the longer bristles ( 13 ).  
     
     
         6 . A mascara brush according to    claim 2   , wherein the diameter (D 1 ) of the inner envelope ( 18 ) is 1 to 8 mm and the diameter (D 2 ) of the outer envelope ( 17 ) is 3 to 15 mm.  
     
     
         7 . A mascara brush according to    claim 1   , wherein the diameter (D 3 ) of the wire-core ( 12 ) in the bristle-covered area is 1.0 to 6.0 mm, preferably approximately 1.3 mm.  
     
     
         8 . A mascara brush according to    claim 1   , wherein the diameter (D 3 ) of the wire core in the region outside the bristle-covered area is 0.75 to 4.0 mm, preferably approximately 1.0 mm.  
     
     
         9 . A mascara brush according to    claim 2   , wherein the bristles ( 13 ) on the outer envelope ( 17 ) are essentially evenly distributed and that 20 to 60 filament tips are located perpendicular to the wire core ( 12 ) of 2 mm height on an imagined cylinder slice of the height H of the outer envelope ( 17 ).  
     
     
         10 . A mascara brush according to    claim 1   , wherein the longer bristles ( 13 ) are partly trimmed in such a way that the trimmed bristle tips are recessed disc-like or helical relative to the outer envelope ( 17 ).  
     
     
         11 . A mascara brush according to    claim 1   , wherein the tips of the longer bristles ( 13 ) are split.  
     
     
         12 . A mascara brush according to    claim 1   , wherein the tips of the longer bristles ( 13 ) are polished.  
     
     
         13 . A mascara brush according to    claim 1   , wherein the shorter bristles ( 14 ) have a maximum filament cross section of 0.03 to 0.15 mm and the longer bristles have a maximum filament cross section of 0.075 to 0.3 mm.  
     
     
         14 . A mascara brush according to    claim 1   , wherein longer and shorter bristles ( 14 ,  13 ) are disposed in one and the same winding of the wire core ( 12 ).  
     
     
         15 . A mascara unit with a mascara brush according to    claim 1   , comprising 
 a container ( 1 ) for accepting liquid mascara having an opening ( 3 ) into which a wiper means ( 4 ) for the mascara brush ( 6 ) is inserted, the mascara brush ( 6 ) being fixed in a closure cap for the container ( 1 ), wherein the free inside diameter (D 3 ) of the wiper means ( 4 ) is slightly smaller than the diameter (D 1 ) of the inner envelope ( 18 ) of the shorter bristles ( 14 ).
