This false nail is used by adhering and fixing it to the surface of a human nail with double-sided tape or adhesive, and has a curved shape as a whole so that it can follow the surface of a human nail. Has been formed.

る。However, since the surface shape of a human nail varies from person to person, it is difficult to fit one artificial nail to every person's nail. Therefore, it is necessary to prepare a plurality of false nails, which increases the manufacturing cost. On the other hand, when using a false nail that does not fit a human nail, the false nail is easily peeled off. Further, since the artificial nail is formed in a curved shape, if a large force is applied to the artificial nail, the artificial nail is likely to be damaged or the like, and the storage thereof should be done with caution.

容易である。Therefore, the applicants have proposed a false nail made of a shape memory polymer (Japanese Patent Application No. 11-3427).
92). Since this false nail is made of a shape memory polymer, it can be deformed to a temperature higher than a predetermined transition temperature, deformed into a predetermined shape in that state, and then heated to a temperature not higher than the above transition temperature. The predetermined shape can be retained. Further, when the temperature is returned to a temperature higher than the transition temperature again, it becomes deformable and can be deformed into the same shape as the predetermined shape or a different shape.
Therefore, the artificial nail can be deformed to a temperature higher than the transition temperature, deformed to fit the surface shape of the human nail, and then kept at the transition temperature or lower to maintain the deformed shape. it can. After use, the artificial nail may be removed from the human nail, deformed into a flat plate shape at a temperature higher than the above transition temperature, and then stored in the flat plate shape at a temperature below the above transition temperature. In this case, since the artificial nail has a flat plate shape, even if a large amount of force is applied to the artificial nail, the artificial nail is less likely to be damaged and is easy to store.

That is, even if the liquid material is injected into the artificial nail forming space (not shown) formed in the mold, the artificial nail 10 (see FIG. 12) having a planar shape (substantially rectangular shape) as shown in FIG. 1 is produced. When the temperature is higher than the above transition temperature, the shape becomes a plane shape (substantially heart shape) as shown in FIG. 13, which is completely different from the surface shape of the human nail. It should be noted that the arrow 11 in FIG. 12 indicates at which position the liquid material gate position in the artificial nail forming space formed in the mold is with respect to the manufactured artificial nail 10.

行う。The artificial nail 4 is attached to a human nail (not shown) as follows. That is, first, when the predetermined artificial nail 4 is larger than a human nail or when the shape of the artificial nail 4 is adjusted, it is ground with a file or the like while being attached to the artificial nail holder. Then, the artificial nail 4 is put in hot water (not shown) at 60 to 65 ° C. to make it deformable. At this time, the artificial nail 4 holds the surface shape of a human nail. Further, the area shrinks by about 2%. Next,
The false nail 4 is taken out of the hot water and separated from the thin plate-like connecting portion 3. Next, after the separated artificial nail 4 is pressed against the surface of a human nail and bent so as to conform to the surface shape, the artificial nail 4 is dried at room temperature in that state.
During this drying, the artificial nails 4 move above the glass transition temperature (about 6
When the temperature is 0 ° C. or lower, the shape of the human nail is maintained according to the surface shape of the nail. Then, after the drying, the artificial nail 4 is attached to the surface of a human nail with a double-sided tape.

（すなわち、人の爪の表面形状が保持されている）。Further, the artificial nail holder of the present invention has a central holding plate, a plurality of connecting portions radially extending from the outer peripheral portion of the central holding plate to the outside, and detachably fixed to each of the connecting portions. The artificial nail can be detached from each of the above-mentioned connecting portions and used at the time of use. Further, in the artificial nail holder of the present invention, a plurality of artificial nails can be fixed to one central holding plate constituting the same, which facilitates storage and transportation of the artificial nails. Further, since the artificial nail holder of the present invention has at least the artificial nail made of the mixed material of the polyurethane-based shape memory polymer and polypropylene, even when the artificial nail is manufactured by an injection molding method or the like, a predetermined transition occurs. The shape of the artificial nail does not change significantly (that is, the surface shape of the human nail is retained) when the temperature is set higher than the temperature to allow deformation.
