File, particularly nail file

Abstract

The file, the body of which is provided on at least part of its surface with a roughness varying from 10 to 100 μm, is made of flat, pressed or hardened glass. The file can have a variety of geometrical shapes and cross sections.

       15 . The nail file of  claim 13 , wherein the glass is transparent.  
   
   
       16 . The nail file of  claim 11 , wherein at least one of the ends tapers to a point.  
   
   
       17 . The nail file of  claim 16 , wherein the end opposite the tapered end is rounded.  
   
   
       18 . The nail file of  claim 11 , wherein at least a portion of each of the first and second sides includes an abrading surface.  
   
   
       19 . A nail file device comprising: 
 a body having a first surface, a second surface opposite the first surface, first and second opposite ends, and first and second opposite edges;    at least a majority of the first surface is roughened, the roughened portion of the first surface extends from the first end toward the second end and extends from the first edge to the second edge, and the roughened portion of the first surface is defined by random peaks and valleys;    the body, the first and second surfaces, the first and second ends, the first and second edges, and the roughened portion of the first surface are integrally formed of a single material, and the material is non-corrosive and moisture impervious.    
   
   
       20 . The nail file of  claim 19 , wherein the roughened portion has a roughness between about 10 μm to about 100 μm.  
   
   
       21 . The nail file of  claim 19 , wherein the material is glass.  
   
   
       22 . The nail file of  claim 21 , wherein the glass is hardened.  
   
   
       23 . The nail file of  claim 21 , wherein the glass is transparent.  
   
   
       24 . The nail file of  claim 19 , wherein at least one of the ends tapers to a point.  
   
   
       25 . The nail file of  claim 24 , wherein the end opposite the tapered end is rounded.  
   
   
       26 . The nail file of  claim 19 , wherein at least a majority of each of the first and second sides are roughened.  
   
   
       27 . A nail file comprising: 
 a body having a first surface, a second since opposite the first surface, first and second opposite ends, and first and second opposite edges;    at least a majority of the first surface is roughened, the roughened portion of the first surface extends from the first end toward the second end and extends from the first edge to the second edge, and the roughened portion of the first surface is defined by random peaks and valleys;    the body, the first and second surfaces, the first and second ends, the first and second edges, and the roughened portion of te first surface are formed of glass.    
   
   
       28 . The nail file of  claim 27 , wherein the roughened portion has a roughness between about 10 μm to about 100 μm.
