Description

  The present invention relates to a method for manufacturing an artificial nail base that can be easily attached to and detached from the nail and hardly peeled off, and a method for manufacturing an artificial nail using the base for an artificial nail.

  In recent years, artificial nails have been used mainly by young women as one of the nail arts for enjoying fingertips. The artificial nail used for this purpose consists of a thin small plastic piece that is curved to follow the shape of the surface of the human nail, and is molded into a beautiful shape, with a clean color, pattern, and pattern on the surface. Etc. are given.

  In general, artificial nails are made as non-decorated products according to size and are commercially available, and the user selects and purchases artificial nails that match the size of their nails. The pattern and pattern on the surface of the artificial nail are drawn on the surface of an undecorated artificial nail that is on the market by yourself using a fine brush and paint or by a nail salon.

Decorated artificial nails are used by sticking and fixing to the surface of human nails using an adhesive or double-sided tape. The artificial nail is generally attached when going out, and removed when doing housework. The artificial nail can be removed from the nail by soaking your hands in hot water.

  By the way, the above-mentioned conventional commercially available artificial nails are made so as to fit the curve of a human nail to some extent, but the artificial nail does not completely match the curvature of the surface of the human nail used. However, there was a problem that it did not stick to the human nails and could be removed from the human nails just by touching the artificial nail for a while.

  For this reason, the artificial nail may be adhered to the human nail with a strong adhesive so that the artificial nail cannot be removed from the human nail even if it hits something. However, if you do this, it will not be removed for a long time, and during that time water enters the gap between the nail and the nail by water work such as housework, where mold grows and the nail is green or It may turn black and cause a symptom called green nail, which is a sanitary problem.

  In order to solve the above-mentioned problem that the artificial nail does not adhere to the human nail, clay-like synthetic resin (acrylic liquid and powder) is placed on the inner surface of the artificial nail, and the inner surface of the artificial nail has the shape of the surface of the nail. Although the method of matching may be taken, when synthetic resin is piled up on the inner surface of an artificial nail, another problem that a fingertip will become heavy with the weight of synthetic resin will arise.

  The problem to be solved by the present invention is that when a commercially available artificial nail is adhered to a human nail with an adhesive, the artificial nail cannot be firmly adhered to the nail, When hit, it is easy to remove from the nail.

  In the present invention, the shape of the outer surface of the nail of the person using the artificial nail and the shape of the inner surface of the artificial nail are matched so that the artificial nail can be peeled off and firmly adhered to the nail using an adhesive. The most important feature.

  As a method for matching the shape of the inner surface of the artificial nail with the shape of the outer surface of the nail of the person using the artificial nail, specifically, an artificial nail base is individually manufactured and used.

  That is, the artificial nail base includes an impression taking process for obtaining an impression of a part including a fingernail of a human fingertip, and a fingertip model of a part including a nail of a human fingertip from the impression taken in the impression taking process A fingertip model forming process for forming a fingertip, a vacuum forming process for vacuum forming a plastic plate using a part including a nail of the fingertip model formed in the fingertip model forming process as a mold, and a plastic plate molded in the vacuum forming process The nail corresponding part is cut out to obtain a base for an artificial nail.

  Here, the fingertip model forming step includes a nail extension portion forming step of extending a nail extension portion extending smoothly from the portion corresponding to the tip portion of the fingertip of the human fingertip toward the tip direction. You may have.

  The artificial nail base thus produced may be used as an artificial nail with a color and / or pattern on the surface, or a pre-made decorated artificial nail may be laminated and bonded onto the artificial nail base. Alternatively, a ready-made blank nail may be laminated and bonded onto the artificial nail base, and a color and / or pattern may be applied to the surface of the artificial nail. The extension nails were laminated and bonded, and the surface of the base for the artificial nail where the extension nails were not stacked and bonded was solidified to the thickness of the extension nails, and the surface of the extension nails and the synthetic resin were solidified A color and / or pattern may be applied to the surface of the part.

  Since the shape of the inner surface of the artificial nail produced according to the present invention is completely identical to the shape of the surface of the nail of the person using the artificial nail (curved, bumpy, etc.), the nail of the person using the artificial nail When the artificial nail is completely in close contact with the surface and adhered with an adhesive, it is difficult to form a gap between the artificial nail and the artificial nail. Therefore, there is an advantage that mold does not grow between the nail and the artificial nail, that is, the nail does not cause skin diseases such as green nail.

  In addition, the artificial nail produced according to the present invention uses the artificial nail when bonded with an adhesive because the shape of the inner surface completely matches the shape of the outer surface of the nail of the person using the artificial nail. There is an advantage that the artificial nail adheres firmly to the surface of the person's nail and therefore cannot be easily removed from the person's nail to the extent that the artificial nail hits something.

  In addition, since the artificial nail made according to the present invention is already compatible with the user's nail, it is not necessary to adjust the shape of the inner surface of the artificial nail to the shape of the user's nail. You only need to do the design. The manicurist has the advantage of being able to do most of the work in the absence of the person.

  Moreover, since the artificial nail produced according to the present invention is produced by vacuum molding, a large number of them can be produced at the same time. Therefore, there is an advantage that productivity is very good.

  The purpose of ensuring that the artificial nail is not easily removed from a person's nail to the extent that the artificial nail hits something is to improve hygiene when using the artificial nail. Realized without causing any worsening situation.

  FIG. 1 is an explanatory view showing the steps of the first embodiment of the present invention. As shown in the figure, the first embodiment of the present invention includes an impression taking process for taking an impression of a part including a fingernail of a human fingertip, and a human fingertip from the impression taken in the impression taking process. A fingertip model forming process for forming a fingertip model of a part including a fingernail, a vacuum forming process for vacuum-molding a plastic plate using a part including a nail of the fingertip model formed in the fingertip model forming process as a mold, and the vacuum A cut-out step of cutting out a portion corresponding to the nail of the plastic plate molded in the molding step to obtain a base for an artificial nail.

  Here, the impression of the fingernail is obtained by pressing the fingernail against the silicon impression material. Inject the gypsum solution into the impression mold, wait for the gypsum liquid to harden and become hardened gypsum, remove the cured gypsum from the impression mold, and use it as a fingernail model. It is preferable to trim the fingernail model on the opposite side of the fingernail with a polishing device so that the fingernail model is as thin as possible as a whole so that the plastic plate does not wrinkle near the nail part in vacuum molding. As the plastic plate, PET resin, acrylic resin, ABS resin, or the like can be used. The thickness of the plastic plate is preferably about 0.3 mm to 1.0 mm.

  FIG. 2 is an explanatory view showing the steps of the second embodiment of the present invention. The basic configuration is the same as in the first embodiment. The fingertip model forming step includes a nail extension portion forming step of extending a nail extension portion extending smoothly from the portion corresponding to the tip portion of a fingertip of a human fingertip toward the tip direction. The point is different. The nail extension is manually formed using a resin or silicon impression material. Here, the plastic plate used for the vacuum molding is preferably a slightly thicker one having a thickness of about 0.5 mm to 1.5 mm because the tip of the artificial nail needs to have a certain degree of strength.

  Next, how to use the artificial nail base manufactured as described above will be described with reference to FIG.

  First, the surface of the artificial nail base produced as described above may be decorated with a color and / or pattern and used as an artificial nail (fake nail 1 in FIG. 3).

  Alternatively, a ready-made decorated artificial nail may be laminated and bonded with an adhesive on the artificial nail base produced as described above and used as an artificial nail (fake nail 2 in FIG. 3). Good.

  In addition, on the artificial nail base prepared as described above, a ready-made non-pattern artificial nail is laminated and bonded with an adhesive, and the surface of this artificial nail is decorated with colors and / or patterns. This may be an artificial nail (fake nail 3 in FIG. 3).

  In addition, a ready-made extension nail is laminated and bonded to the tip of the artificial nail base manufactured as described above with an adhesive, and a synthetic resin (on the surface of the artificial nail base where the extension nail is not laminated or bonded Acrylic resin or UV curable resin) is applied to the thickness of the extended nail to eliminate the level difference, and the surface of the extended nail surface and the portion where the synthetic resin is applied is decorated with a color and / or pattern. It may be used as an artificial nail (an artificial nail 4 in FIG. 3).

  The artificial nail produced as described above is used by being adhered to a human nail by using a double-sided tape or an adhesive.

  Since the shape of the inner surface of this artificial nail completely matches the shape of the outer surface of the nail of the person using the artificial nail, the artificial nail is in close contact with the surface of the person's nail using the artificial nail, It is difficult to form a gap between the nail of the person using the artificial nail, and water does not enter between the nail and the artificial nail even when doing housework. Mold does not breed.

  In addition, since the shape of the inner surface of this artificial nail matches the shape of the outer surface of the nail of the person using the artificial nail, the artificial nail adheres firmly to the surface of the person's nail using the artificial nail. Therefore, it cannot be easily removed from a person's nail to the extent that the artificial nail hits something.

  In addition, since the shape of the inner surface of the artificial nail completely matches the shape of the outer surface of the nail of the person using the artificial nail, it can be firmly adhered to the nail using an adhesive or double-sided tape. . And since an adhesive or a double-sided tape can be used as an adhesion | attachment means, when it wants to remove an artificial nail, an artificial nail can be forcibly peeled from a nail.
