Callus-removing skin-file and method of manufacturing the same
View Patent ↗The present invention relates to a callus-removing skin-file capable of removing fingernails, toenails, calluses and the like and a method of manufacturing the same. The callus removing file 21 , comprises a base plate 24 made of glass, an abrasive layer 23 formed on the base plate by sanding; and a coating layer 22 coated on the upper surface of the abrasive layer 23 with a mixture of epoxy resin, a hardening agent and emery. The method of manufacturing the callus-removing skin-file includes the steps of: preparing a base plate 24 made from glass material; making a mixture by mixing 20 to 25 percent by weight epoxy resin, a 40 to 55 percent by weight hardening agent and 15 to 20 percent by weight emery; forming an abrasive layer 23 by sanding a surface of the base plate 24 ; coating the mixture on the upper surface of the sanded base plate; and hardening the base plate 24 coated with the mixture.
1. A callus-removing skin-file, comprising:
a base plate made of glass;
an abrasive layer formed on the base plate by sanding; and
a coating layer coated on the upper surface of the abrasive layer with a mixture of epoxy resin, a hardening agent and emery.
2. The callus-removing skin-file of claim 1 , wherein the amount of epoxy resin is 20 to 25 percent by weight, the amount of the hardening agent is 40 to 55 percent by weight and the amount of the emery is 15 to 20 percent by weight.
3. The callus-removing skin-file of claim 1 , further comprising a protective layer formed on the back surface of the base plate which prevents the spread of pieces of glass upon the breakage of the base plate.
4. The callus-removing skin-file of claim 1 , further comprising a brush formed on the back surface of the base plate which brushes up calluses.
5. The callus-removing skin-file of claim 1 , further comprising a handle portion formed on at least one part of the base plate to which various kinds of advertisements are attachable.
6. The callus-removing skin-file of claim 1 , further comprising a groove formed on at least one part of the base plate to which a mirror is attachable.
7. A method of manufacturing a callus-removing skin-file comprising the steps of:
preparing a base plate made from glass material;
making a mixture by mixing 20 to 25 percent by weight epoxy resin, a 40 to 55 percent by weight hardening agent and 15 to 20 percent by weight emery;
forming an abrasive layer by sanding a surface of the base plate;
coating the mixture on the upper surface of the sanded base plate; and
hardening the base plate coated with the mixture.
8. The method of claim 7 , wherein the glass material is one of selected from plate glass, press glass, flat glass, colored glass and specific glass such as water glass, ripple glass, etc.
