  • the present invention relates to an artificial nail having an enhanced adhesive and shape-keeping property, in particular the artificial nail to adhere closely on a surface of a real nail and to maintain such condition for a long time.
  • the artificial nail has an advantage to enhance aesthetic appearance of a hand, but may have a problem that a bad effect of a chemical substance may be made on a skin around the nail because the artificial nail is made of a polymer and is attached with some chemical adhesive. And also, various bacteria or germs may be generated if a gap is made between the artificial nail and a real nail and moisture soaks into the gap. Therefore, it is necessary for an artificial nail capable of overcoming such problem to be made.
  • Korean patent registration no. 10-1919951 discloses a flexible artificial nail.
  • PCT publication no. WO 2009/119963 discloses an artificial nail with a plurality of section.
  • the known inventions have an advantage that the adhesive property between the real nail and the artificial nail may be improved by making a shape of the artificial nail corresponding to that of the real nail. But a partial separated area between the real nail and the artificial nail may be generated in an adhered condition because of the non-uniformity along a longitudinal direction or a width direction of the nail. Therefore, it is necessary for an artificial nail capable of solving such problem to be made.
  • the present invention has a purpose to solve the above-mentioned problem as below.
  • One purpose of the present invention is to provide with an artificial nail having an enhanced adhesive and shape-keeping property between a real nail and the artificial nail by forming an adhesive pattern on at least one part of an adhesive surface of the artificial nail.
  • Another purpose of the present invention is to provide with the artificial nail with an improved aesthetic property by maintaining an adhesive property of the artificial nail to a real nail and a curved shape of the artificial nail in a course of a human activity.
  • an artificial nail comprises an exposed part exposed to an outside and an adhesive surface adhered on a real nail, and is characterized in that an adhesion pattern is formed on at least one portion of the adhesive surface and the least one portion has different heights along a longitudinal direction or a width direction in regard to a base surface.
  • the adhesive surface becomes a curved surface along the width direction.
  • the artificial nail has a bending property based on a center line of the longitudinal direction.
  • a guiding part is formed an inner side of the adhesion pattern.
  • At least one portion of the artificial nail is made of at least one material selected from a group consisting of an acrylonitrile butadiene styrene, a polyurethane, an acryl, a polypropylene and a polyethylene.
  • a section of the adhesion pattern along a horizontal direction become a plurality of polygons, a plurality of ellipses or a plurality of circles.
  • the adhesion pattern has a protruded shape, and the height of the adhesion pattern becomes decreasing gradually along the longitudinal direction or the width direction.
  • FIG. 1 shows an embodiment of an artificial nail having an enhanced adhesive and shape-keeping Property according to the present invention.
