Dual hemisphere cosmetic brush

Abstract

A brush for applying mascara or the like, having at least two separate bristle arrays, each bristle array forming a distinct portion of the resulting brush and/or providing for a different function, such as mascara application or combing.

1 . A cosmetic applicator brush including:
 (a) an elongated core having a first end and second end;   (b) a first array of bristles attached to a first portion of the elongated core, the bristles having free tips defining a first notional envelope;   (c) a second array of bristles attached to a second portion of the elongated core, the bristles having free tips defining a second notional envelope; and   (d) a connection section along a third portion of the elongated core between the first array and the second array.   
   
   
       2 . The cosmetic applicator brush of  claim 1 , wherein each of the first notional envelope and the second notional envelope have a respective flat side. 
   
   
       3 . The cosmetic applicator brush of  claim 2 , wherein the connection section further comprises a bend such that the flat side of the first notional envelope cooperates with the flat side of the second notional envelope. 
   
   
       4 . The cosmetic applicator brush of  claim 1 , wherein the bristles of the first array differ from the bristles of the second array with respect to one or more physical properties affecting the application of a cosmetic material. 
   
   
       5 . The cosmetic applicator brush of  claim 1 , wherein at least a portion of the first notional envelope and at least a portion of the second notional envelope each taper toward the connection section. 
   
   
       6 . The cosmetic applicator brush of  claim 1 , wherein the first end and the second end are secured together. 
   
   
       7 . The cosmetic applicator brush of  claim 1 , wherein the first notional envelope differs from of the second notional envelope. 
   
   
       8 . The cosmetic applicator brush of  claim 1 , wherein the first notional envelope is flipped with respect to the second notional envelope. 
   
   
       9 . The cosmetic applicator brush of  claim 1 , wherein at least one of the notional envelopes is adapted for combing eyelashes. 
   
   
       10 . A method of making a cosmetic applicator brush, comprising:
 (a) attaching a first array of bristles to an elongated core between a first end of the elongated core and a connection section of the elongated core;   (b) attaching a second array of bristles to the elongated core between a second end of the elongated core and the connecting section of the elongated core;   (c) trimming the bristles of first array such that the free tips of the bristles of the first array define a first notional envelope; and   (d) trimming the bristles of the second array such that the free tips of the second array define a second notional envelope   
   
   
       11 . The method of  claim 10  further comprising the step of:
 forming a bend in the connection section such that the first array and the second array cooperate to form the cosmetic applicator brush.   
   
   
       12 . The method of  claim 10  wherein at least one of the first trimming step and the second trimming step further comprise the step of:
 forming a generally flat side proximate the elongated core.   
   
   
       13 . The method of  claim 10  further comprising the step of:
 securing the first end and the second end.
