Mascara brush, a manufacturing method and a mascara reservoir for same

Abstract

A mascara brush comprises a plurality of bristles. These are held by a bristle carrier comprising at least two curved core sections extending from a common handle section. In a method for manufacturing said mascara brush, the two cores are bent jointly between a bending plunger and a counter-plunger of a bending tool. Said mascara brush can be used with a mascara reservoir having a circular mascara wiping aperture. The result is a mascara brush allowing a good predetermination of the amount of mascara to be applied. Further, an improved combing result and a curl effect can be achieved.

What is claimed is:  
     
         1 . A mascara brush comprising a plurality of bristles held between two intertwisted wire sections forming a core, with said core comprising a curved core section, wherein at least two curved cores ( 2 ,  3 ) extending from a common handle section ( 5 ) are provided.  
     
     
         2 . A mascara brush according to  claim 1 , wherein said cores ( 2 ,  3 ) have essentially the same bending radius.  
     
     
         3 . A mascara brush according to  claim 1 , wherein transition sections ( 6 ,  7 ) of said cores ( 2 ,  3 ) adjacent to said handle section ( 5 ) have different transition angles relative to said handle section ( 5 ).  
     
     
         4 . A mascara brush according to  claim 1 , wherein said handle section ( 5 ) is formed of bristle-free intertwisted wire sections being extensions of said cores ( 2 ,  3 ).  
     
     
         5 . A mascara brush according to  claim 1 , wherein said bristle-free sections of said cores ( 2 ,  3 ) in the handle section ( 5 ) are positioned in parallel and are connected with each other.  
     
     
         6 . A mascara brush according to  claim 1 , wherein tangents (T 2 , T 3 ) of said cores ( 2 ,  3 ) intersecting in a starting point (E) form an angle β which is larger than 0°.  
     
     
         7 . A mascara brush according to  claim 1 , wherein a bristle contour ( 8 ,  9 ) of said cores ( 2 ,  3 ) has one of the following shapes: 
 cylindrical,    barrel-shaped,    shape of truncated cone tapering on one or both sides,    shape of truncated cone,    centrally waisted    centrally waisted with a truncated cone tapering on both sides.    
     
     
         8 . A mascara brush according to  claim 1 , wherein a bristle contour ( 8 , 9 ) of said cores ( 2 ,  3 ) has one of the following cross-sectional shapes: 
 round,    elliptical,    triangular, especially with rounded corners,    rectangular, especially square-shaped, especially with rounded corners.    
     
     
         9 . A mascara brush according to  claim 1 , wherein said bristles ( 4 ) are made of plastic fibres or natural fibres.  
     
     
         10 . A mascara brush according to  claim 1 , wherein said handle section ( 5 ) is attached in a stem section centrally or off-centre.  
     
     
         11 . A mascara brush according to  claim 1 , wherein the stem section has a diameter ranging from 1.8 mm to 5.0 mm.  
     
     
         12 . A mascara brush according to  claim 1 , wherein instead of said curved cores ( 2 ,  3 ) at least one of said two cores is formed as a straight core.  
     
     
         13 . A method for manufacturing a mascara brush comprising a plurality of bristles held between two intertwisted wire sections forming a core, with said core comprising a curved core section, including the steps of: 
 manufacturing a raw brush having at least two straight cores extending from a common handle section ( 5 );    inserting said cores into a bending tool having a convex bending plunger ( 12 ) and a concave counter-plunger ( 13 ) being essentially complementary thereto;    bending said cores, wherein said bending plunger ( 12 ) and said counter-plunger ( 13 ) are moved towards each other and then away from each other;    taking said cores ( 2 ,  3 ) out of said bending tool.    
     
     
         14 . The use of a mascara reservoir ( 14 ) comprising a circular mascara wiping aperture ( 17 ), through which said mascara brush ( 1 ) is insertable into said mascara reservoir ( 14 ), for a mascara brush ( 1 ) according to any of claims  1  through  7 .
