Disk-Style Mascara Brush with Spacers Between Disks

Abstract

This disclosure relates to disk-style mascara brushes having thin plastic sheets and/or molded plastic used as spacers inserted between the bristle-containing disks. The spacers precisely control and adjust the axial distance between each bristle-containing disk and bristles so that the mascara brush is configured for optimal mascara deposit and eyelash separation.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
         1 . A method of making an applicator brush, comprising:
 obtaining molded bristle-containing disks;   obtaining spacers; and   assembling the molded bristle-containing disks in an axially aligned manner while inserting one or more spacers between an adjacent two of the bristle-containing disks.   
     
     
         2 . The method of  claim 1 , further comprising placing two or more of the spacers between the adjacent two of the bristle-containing disks. 
     
     
         3 . The method of  claim 1 , further comprising:
 prior to assembling the bristle-containing disks, determining a distance to be achieved between bristles of the adjacent two bristle-containing disks;   selecting two or more spacers, wherein a total thickness of the two or more spacers is about equal to the distance; and   inserting the two or more spacers to create the distance between the bristles of the adjacent two bristle-containing disks.   
     
     
         2 . The method of claim  3 , wherein two or more of the spacers have similar thicknesses. 
     
     
         3 . The method of claim  3 , wherein two or more of the spacers have different thicknesses. 
     
     
         6 . The method of  claim 1 , further comprising:
 prior to assembling the bristle-containing disks, determining a distance to be achieved between bristles of the adjacent two bristle-containing disks;   selecting a spacer having a thickness about equal to the distance; and   inserting the spacer to create the distance between the bristles of the adjacent two bristle-containing disks.   
     
     
         7 . The method of  claim 1 , further comprising:
 assembling a first brush with the bristle-containing disks, wherein the first brush has a first distance between bristles;   assembling a second brush with the bristle-containing disks, wherein the second brush has bristle-containing disks having a thickness similar to the bristle-containing disks of the first brush, wherein the second brush has a second distance between bristles different than the first distance.   
     
     
         4 . The method of claim  7 , wherein the second brush includes spacers between adjacent bristle-containing disks, and the first brush does not include spacers. 
     
     
         9 . The method of  claim 7 , wherein the first brush and the second brush include a different number or different thickness of spacers between the bristle-containing disks that result in different distances between bristles using the bristle-containing disks of similar thickness. 
     
     
         10 . An applicator brush, comprising:
 bristle-containing disks arranged axially to form a brush; and   at least one spacer is between an adjacent two of the bristle-containing disks.   
     
     
         11 . The applicator brush of  claim 10 , wherein the bristle-containing disks are molded from an elastomer. 
     
     
         12 . The applicator brush of  claim 10 , further comprising a plurality of spacers, a spacer is located between every adjacent two of the bristle-containing disks. 
     
     
         13 . The applicator brush of  claim 10 , further comprising more than one spacer between any adjacent two of the bristle-containing disks. 
     
     
         14 . The applicator brush of  claim 10 , wherein each of bristle-containing disks and each of the spacers is an individual component. 
     
     
         15 . The applicator brush of  claim 10 , wherein a thickness of the spacers is from 0.05 mm to 0.2 mm.
