Description

  The present invention relates to a method for forming an artificial nail for decorating a user's own nail.

  Conventionally, it has been practiced to enjoy the fashionability of fingertips by applying desired decorations such as art and 3D (three-dimensional) to the nails mainly by women, and usually decorating the nails by a professional called a manicurist There are many cases. Thus, when a manicurist or the like applies decoration directly to a user's own nail, the artificial nail is generally applied by directly applying a liquid resin obtained by dissolving acrylic powder in a solution onto the user's own nail. A method of forming on the surface of the user's own nails, or by applying a gel-like photocurable resin directly on the user's own nails to form and then curing by irradiation with ultraviolet rays For example, a method of forming artificial nails on the surface is used.

  However, the above-described method requires a great amount of time exceeding several hours in some cases, and the cost for decoration is high. In addition, the decoration by these methods is expensive because the decoration is maintained only for a few weeks and must be regularly provided. Further, the monomer as a solvent has a problem of hygiene such that the odor is stiff and there is a risk of causing allergies to the nails and surrounding skin.

  On the other hand, instead of directly applying a solution or gel-like photocurable resin to the user's own nail to form an artificial nail on the surface of the user's own nail, a pre-shaped artificial nail (nail chip) Conventionally, a method for forming an artificial nail that adheres to the surface of the user's own nail is known (Patent Documents 1 and 2 below).

  In this Patent Document 1, a mold that transmits ultraviolet light or the like is manufactured, a photocurable resin is cast into the mold, and cured by irradiation with ultraviolet light or the like to manufacture an artificial nail. The nail is adhered to the user's own nail.

  Also, in Patent Document 2, the periphery of a fingertip portion including the user's own nails is molded with an impression material to form a mold, and a room temperature curable resin or the like is poured into the mold and the user's fingertip The replica is manufactured and an artificial nail is formed on the surface of the replica nail, and then the artificial nail is separated from the replica and attached to the user's own nail.

  However, in the conventional artificial nail formation method described above, when a pre-shaped artificial nail is used, since the shape is fixed, it corresponds to a shape (particularly a curved shape) that is different for each user. A wide variety of artificial nails of various shapes must be prepared. For this reason, it is necessary to prepare an enormous amount of artificial nails, which is difficult in both production and sales.

  In addition, when an artificial nail is formed using a replica of a user's finger part, an artificial nail that matches the shape of the user's own nail can be formed, but a formwork for producing a replica of the finger part is formed. The work to do was troublesome.

  The present invention has been made in view of the above-described problems, and provides an artificial nail forming method capable of easily and reliably forming an artificial nail according to the curved shape of each user's own nail. With the goal.

  The method for forming an artificial nail according to the present invention is a method for decorating a user's own nail, and in order to achieve the above-mentioned purpose, a predetermined liquid mixture is cured by curing a liquid mixture of a synthetic resin and a monomer.

According to this, an artificial nail having a predetermined shape is formed by curing a liquid mixture of a synthetic resin and a monomer, and the artificial nail is heated and softened at a predetermined temperature. The artificial nail is deformed along the curved shape of the user's own nail by bringing it into close contact with the surface of the user's nail, reshaped by cooling and hardening the artificial nail, and the artificial nail is adhered to the user's own nail. Since the artificial nail is once molded and then reshaped to match the shape of the user's own nail, the artificial nail corresponding to the curved shape of each user's own nail can be easily and reliably formed. Can do.

  The synthetic resin is preferably a fine powder acrylic resin. According to this, since the artificial nail is softened by heat that can be generated by daily necessities such as a dryer, the user can easily deform the artificial nail.

  Moreover, the formation method of the artificial nail using the thin plate-shaped printing auxiliary member in which the some insertion hole for fitting the said artificial nail was formed in the surface may be sufficient. According to this, since the preparation in the decoration of the artificial nail can be completed by performing the decoration printing, the subsequent decoration of the artificial nail can be simplified.

  An artificial nail according to another aspect of the present invention is an artificial nail used in the method for forming an artificial nail according to claim 2 or claim 3, and cures a liquid mixture of fine powder acrylic resin and monomer. It is characterized by being formed into a predetermined shape. According to this, since the artificial nail is softened by heat that can be generated by daily necessities such as a dryer, the user can easily deform the artificial nail.

  According to the present invention, an artificial nail having a predetermined shape is formed by curing a liquid mixture of a synthetic resin and a monomer, and the artificial nail is heated and softened at a predetermined temperature. The artificial nail is deformed along the curved shape of the user's own nail by bringing it into close contact with the surface of the user's own nail, and the artificial nail is reshaped by cooling and hardening, and the artificial nail is bonded to the user's own nail. As a result, the artificial nail is molded once and then reshaped so as to match the shape of the user's own nail. Therefore, the artificial nail according to the curved shape of each user's own nail is easily and reliably formed. be able to.

  For this reason, since the user can decorate his / her own nails, it is not necessary for the manicurist to decorate his / her nails. Therefore, it is possible to greatly reduce the time required for the nails to decorate their nails and to save the time required for going to and from the nail salon. In addition, it is possible to reduce the cost of decorating the self-nails at a nail salon or the like. Moreover, since a solution or gel-like photocurable resin is not applied directly, it is safe in terms of hygiene.
