Nail file

Abstract

A nail file that can prevent clogging without frequently performing an operation of removing filings from file teeth and can effectively enhance grindability is usable to quickly files nails. The nail file includes a plate-shaped base material, and a plurality of through-holes. The plurality of through-holes are formed on the base material, have opening portions as file teeth at both ends, and a shape of at least each of the opening portions at one end is a polygon. The opening portions at both the ends of the through-holes, the shape of each of the opening portions at the one end may be preferably a polygon, and the shape of each of the opening portions at the other end may be preferably a circle.

1 . A nail file comprising:
 a plate-shaped base material; and   a plurality of through-holes that are formed on the base material, and have opening portions as file teeth at both ends, of the opening portions at both the ends, a shape of each of the opening portions that are open to one surface of the base material is a polygon, a shape of each of the opening portions that are open to another surface of the base material is a circle, and an area of each of the opening portions that are open to the one surface is made larger than an area of each of the opening portions that are open to the other surface.   
     
     
         2 . The nail file according to  claim 1 , wherein the base material has a polishing region in which the opening portions are formed, on a front surface, the polygon as the shape of each of the opening portions is one type selected from a triangle, a quadrangle, and a hexagon, and the opening portions the shape of each of which is one type of a triangle, a quadrangle, and a hexagon are arranged to planarly fill the polishing region. 
     
     
         3 . The nail file according to  claim 2 , wherein the polygon as the shape of each of the opening portions is a regular hexagon, and the opening portions the shape of each of which is a regular hexagon are arranged in a honeycomb shape in the polishing region. 
     
     
         4 . The nail file according to  claim 3 , wherein the base material has a total of four polishing regions, two on the one surface and two on the other surface, first opening portions of a regular hexagon are formed in a first polishing region on the one surface, second opening portions of a circle are formed in a second polishing region on the other surface, third opening portions of a regular hexagon having a smaller size than the first opening portions are formed in a third polishing region on the one surface, and fourth opening portions of a circle having a smaller size than the second opening portions are formed in a fourth polishing region on the other surface. 
     
     
         5 . The nail file according to  claim 1 , wherein the base material is formed from 18-8 stainless steel. 
     
     
         6 . The nail file according to  2 , wherein the base material is formed from 18-8 stainless steel. 
     
     
         7 . The nail file according to  claim 3 , wherein the base material is formed from 18-8 stainless steel. 
     
     
         8 . The nail file according to  claim 4 , wherein the base material is formed from 18-8 stainless steel.
