Abstract

The eyelash lengthening platform for an eyelash perm has a cross-sectional shape that resembles an airplane wing cross-section. The front portion is rounded to provide some curl to the eyelashes. The middle portion and back portion have a slight curvature to their top surface. The middle portion and back portion provide extra surface support for long eyelashes and keep the tips of the eyelash straight, for the appearance of longer length.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . An eyelash lengthening platform for eyelashes comprising: 
 a) a front portion having a circumference;    b) a middle portion adjacent to the front portion; and    c) a back portion radially projecting from the middle portion,    wherein the front portion, the middle portion and the back portion forming a top surface having a convex shape and forming a bottom surface having a concave shape.    
     
     
         2 . The eyelash lengthening platform of  claim 1 , wherein the front portion having a height ‘h 2 ’, wherein the middle portion having a height ‘h 1 ’, wherein the back portion having a height ‘h 3 ’, and wherein ‘h 1 ’ is greater than ‘h 2 ’, and ‘h 1 ’ is greater than ‘h 3 ’.  
     
     
         3 . The eyelash lengthening platform of  claim 2 , wherein ‘h 2 ’ is greater than ‘h 3 ’ 
     
     
         4 . The eyelash lengthening platform of  claim 3 , further having a back tip, wherein the top surface and the bottom surface intersect at the back tip thereby forming an angle “theta”, wherein the angle “theta” is between about 5 degrees and about 45 degrees.  
     
     
         5 . The eyelash lengthening platform of  claim 4 , wherein the angle “theta” is between about 10 degrees and about 15 degrees.  
     
     
         6 . The eyelash lengthening platform of  claim 5 , wherein the bottom surface having a front edge, wherein the front edge forming a substantially half-moon arc shape.  
     
     
         7 . The eyelash lengthening platform of  claim 6 , wherein the circumference forming a substantially arc shape.  
     
     
         8 . The eyelash lengthening platform of  claim 7 , further comprising a first extension having a first end and a second extension having a second end, wherein the first end and the front edge form an angle ‘Alpha-1’, and wherein the second end and the front edge form an angle ‘Alpha-2’, and whereby the first extension and the second extension provide additional surface area for supporting the eyelashes.  
     
     
         9 . The eyelash lengthening platform of  claim 6 , wherein the angle ‘Alpha-1’ is between about 100 degrees and about 120 degrees.  
     
     
         10 . The eyelash lengthening platform of  claim 4 , wherein the front edge having a center, wherein the front edge having a height ‘H 4 ’ at the center, and having a height ‘H 5 ’ about adjacent to the first end, and having a height ‘H 6 ’ about adjacent to the second end, and wherein ‘H 4 ’ is greater than ‘H 5 ’, and ‘H 4 ’ is greater than ‘H 6 ’.  
     
     
         11 . The eyelash lengthening platform of  claim 7 , wherein the convex shape of the upper surface is reduced, such that the upper surface is substantially linear.  
     
     
         12 . The eyelash lengthening platform of  claim 11 , wherein the platform having a maximum depth ‘D 1 ’, wherein ‘D 1 ’ is greater than two times ‘h 1 ’.  
     
     
         13 . An eyelash lengthening platform for eyelashes comprising: 
 d) a front portion having a circumference;    e) a middle portion adjacent to the front portion; and    f) a back portion radially projecting from the middle portion,    wherein the front portion, the middle portion and the back portion forming a top surface having a convex shape and forming a bottom surface having a concave shape; wherein the circumference varies in amount of curvature, whereby the root of the eyelashes bend around the circumference, whereby the body and tip of the eyelashes lie substantially perpendicular to the top surface, such that the bending of the root uplifts the eyelashes, and such that the body and tip are maximized in straight length.    
     
     
         14 . The eyelash lengthening platform of  claim 13 , wherein the front portion having a height ‘h 2 ’, wherein the middle portion having a height ‘h 1 ’, wherein the back portion having a height ‘h 3 ’, and wherein ‘h 1 ’ is greater than ‘h 2 ’, and ‘h 1 ’ is greater than ‘h 3 ’.  
     
     
         15 . The eyelash lengthening platform of  claim 14 , wherein ‘h 2 ’ is greater than ‘h 3 ’.  
     
     
         16 . The eyelash lengthening platform of  claim 15 , further having a back tip, wherein the top surface and the bottom surface intersect at the back tip thereby forming an angle “theta”, wherein the angle “theta” is between about 5 degrees and about 45 degrees.  
     
     
         17 . The eyelash lengthening platform of  claim 16 , wherein the angle “theta” is between about 10 degrees and about 15 degrees.  
     
     
         18 . The eyelash lengthening platform of  claim 17 , wherein the bottom surface having a front edge, wherein the front edge forming a substantially half-moon arc shape.  
     
     
         19 . The eyelash lengthening platform of  claim 18 , wherein the circumference forming a substantially arc shape.
