Description

The present invention relates to nail decoration of how to apply the decoration to the nail.

Conventionally, there are mainly the following three methods for decorating nails in a nail salon.
First, what is called a gel nail is a large market share. Gel nail is a photopolymerization (photopolymer) in which a fluid synthetic resin (viscous liquid) is applied to the nails and cured by irradiating with ultraviolet rays (UV (Ultraviolet) -A) or visible rays (Vis (Visible)). The reaction is used as a nail material. Specifically, the practitioner applies a water tank-like urethane material to the customer's nails and irradiates with light to cure. Urethane is in a water tank shape and is characterized by being placed on any nail (easy to adhere).
The decoration is done manually by the practitioner on a colored gel that has been cured on the customer's nails.

Second, there is an artificial nail technique using a plastic acrylic material. The procedure for this technique is as follows.
First, stick a transparent plastic nail with a bond. Then cut to your preferred length. Next, primer is applied, acrylic powder is applied to the monomer, solidified, applied onto the nail, shaped to create an artificial nail, and finished with art to finish an average of 2 to finish 10 fingers. It takes time. In about 2 weeks, water enters from the gap between the nail and the artificial nail of acrylic (because acrylic has poor adhesion to the nail), and mold is formed on the nail.

Third, there is a manicure technique. The practitioner manually applies the manicure to the customer's nails, and the decoration is also performed manually using a brush.
Another manicure technique is the manicure film type. For example, a base color top three-layer manicure film is attached to the nail.
In addition, there is a rubber (rubber) material as a film type. A rubber material may peel from the nail | claw stuck in 1-2 days by the difference in material with a base gel, or weakness to water.
There are the following as prior art documents of known inventions related to the present application.

Japanese Patent No. 4197731 US7,861,730B2

By the way, the first gel nail technique uses a water tank-like urethane material, and therefore has a drawback of long treatment time. For example, it takes about an hour for the practitioner to perform on the ten fingernails of the customer.
In addition, a water tank-like urethane material often sticks unintentionally to a practitioner's hand. Furthermore, if the lid of the urethane material container is not securely closed, the urethane material may inhale and leak or swell from the container. Therefore, there is a problem that it is not preferable in terms of hygiene in handling at the nail salon.
In addition, the decoration with the gel nail takes time because it is performed manually by the practitioner, and there is a large difference in skill between the beginner and the skilled person, which may cause a difference in the quality of the nail art. In addition, since the practitioner performs the work manually, there is a drawback that the width of the nail art is narrow.

The technique of the artificial nail using the second acrylic material has a drawback that the nail cannot evaporate. The transpiration exercise is a function of the nail to release moisture to the outside, and it feels that the nail cannot breathe.
There is a drawback that the joint between the nail and the artificial nail has only one week. Furthermore, there is a drawback that the urethane paint for decoration is poorly applied to the cured urethane color gel. Further, when the uncured gel is wiped off with an acetone-based solution at the end of the treatment, the nail art may disappear if the solution enters from the gap.
In addition, since the practitioner performs the decoration manually, it takes time, as in the first gel nail technique, and the difference in skill between beginners and experts may be large, resulting in differences in the quality of nail art. . In addition, there is a drawback that the width of nail art is narrow.

The third manicure technique has the disadvantage that the manicure (including nitrocellulose and the like) cannot evaporate the nails. In addition, since the decoration on the nails is performed manually, it takes time, as in the first gel nail technique, and the difference in skill between the beginner and the skilled person is large, which may cause a difference in the appearance of the decoration. In addition, there is a drawback that the width of nail art is narrow.
In addition, the film-type manicure has the disadvantage that it only sticks to the nails for about two weeks and may peel off after about two weeks.
Further, as a film type, the rubber (rubber) material has a problem that the nail cannot evaporate and the sticking property to the nail is low.

In view of the above circumstances, can in a short time easily treatment of nail art, and an object thereof is to provide a quality high nail decoration how.

  In order to achieve the above object, a nail decoration method according to the first aspect of the present invention is a nail decoration method for decorating nails, wherein a base gel application process in which a base gel containing urethane resin is applied on the nails, A base gel curing process in which the base gel on the nail is cured, and a nail sheet member including a urethane resin having a solid shape with flexibility and a thicker central part than the peripheral part are attached to the base gel. Sheet sticking process, sheet member curing process in which the nail sheet member is cured, top gel application process in which a top gel containing urethane resin is applied on the nail sheet member, and top gel on the nail sheet member A top gel curing process in which is cured.

  The nail decoration method according to the second aspect of the present invention protrudes from the nail of the adhered nail sheet member between the sheet sticking process and the sheet member curing process of the nail decoration method of the first aspect of the present invention. It includes a cutting process in which points are cut.

  The nail decoration method according to the third aspect of the present invention is a nail decoration method for decorating nails, wherein a base gel application process in which a base gel containing urethane resin is applied on the nails, and the base gel on the nails is cured The base gel is cured, and the base gel on the nail on the outer side of the nail from between the cuticle of the nail and the fingertip is solid and flexible, and the center is thicker than the periphery. A first sheet sticking process in which a first nail sheet member containing a urethane resin is attached, a sheet member hardening process in which the first nail sheet member is cured, and on the base gel and the first nail sheet member A second sheet sticking process in which a second nail sheet member including a urethane resin having a flexible solid shape and a thicker central part than the peripheral part is attached to the second nail Comprising a top gel coating process top gel is painted containing a urethane resin on over preparative member, and a top gel curing process where the top gel is cured.

  The nail decoration method according to the fourth aspect of the present invention is the first nail sheet member adhered between the first sheet attachment process and the sheet member curing process of the nail decoration method of the third aspect of the present invention. The first nail sheet member and the second nail sheet member include the first cutting process in which a portion protruding from the nail is cut, and the second nail sheet member and the second nail sheet member are interposed between the second sheet attaching process and the top gel application process.

<< Embodiment 1 >>
FIG. 1A is a top view of the nail 3 applied with a single nail decoration sheet 1 in the nail decoration method of the first embodiment, and FIG. It is a side view containing the AA line partial cross section of a).
The nail decoration sheet 1 used for the nail decoration (art) of the first embodiment is a so-called artificial nail nail art article of a sheet type for applying decoration on a nail.

  In the nail art (nail decoration method) according to the first embodiment, a base gel 4 containing urethane is applied onto a nail 3 of a finger 2 and cured. And the nail decoration sheet 1 is stuck on the hardened base gel 4, and the top gel 5 of a urethane resin is apply | coated on the stuck nail decoration sheet 1, and is hardened. That is, the solid (solid-state) nail decoration sheet 1 is sandwiched between the base gel 4 on the nail 3 and the top gel 5 arranged at the outermost part.

The nail decoration sheet 1 is fixed on the base gel 4 with an uncured gel of the base gel 4. The uncured gel refers to ultraviolet rays (UV (Ultraviolet) -A) due to oxygen (O ₂ ) in the air between the light such as ultraviolet rays and visible rays and the gel nails when the gel nails are cured. A gel that is blocked from light such as visible light (Visible) and does not harden.
Note that an adhesive layer may be provided on the surface of the nail decoration sheet 1, and the nail decoration sheet 1 may be adhered (attached) to the base gel 4 with the adhesive layer.

The nail decoration sheet 1 is made of a urethane resin containing a photocurable urethane acrylate oligomer such as UV or LED (Light Emitting Diode). By applying a material containing urethane acrylate oligomer as a component to the nail decoration sheet 1, even if it is attached (attached) on the nail 3, the nail transpiration is not hindered. Further, both the base gel 4 and the top gel 5 are made of a material including a urethane resin that does not limit the transpiration motion of the nail 3. For example, as the base gel 4 and the top gel 5, commercially available calgel (trade name: manufactured by MOGA / BROOK) or ace gel (trade name: manufactured by Nail Partner Co., Ltd.) can be used.
Therefore, the person to be treated does not feel stuffy in the nail 3 after the treatment (nail art).
In addition, the nail decoration sheet | seat 1 may contain components other than the urethane resin containing a urethane acrylate oligomer, as long as it does not prevent the transpiration | evaporation movement of a nail | claw.

2 (a) is a plan view of the nail decoration sheet 1 used in the nail decoration method of Embodiment 1, FIG. 2 (b) is a view in the direction of arrow B in FIG. 2 (a), and FIG. 2 (c). These are C direction arrow directional views of Fig.2 (a).
The nail decoration sheet 1 is formed into a flexible solid (solid) sheet (flakes) so as to be placed along the fingernails or toenails of various people.
The nail decoration sheet 1 is formed into a solid (solid) shape having a shape in which a middle portion (center portion) having a thick central portion and a thin peripheral portion is raised, and is high at the center portion of the nail, so-called, A high point of the nail (the highest point where the nail looks beautiful) is formed to make it look beautiful after art. The nail decoration sheet 1 can be used not only for the nail of a hand but also for a nail of a foot.

As shown in FIG. 1, the nail decoration sheet 1 is positioned at the boundary between the cuticle 2a of the finger 2 and the nail 3, and has almost the same length as the toe 3s (refer to the cc two-dot chain line in FIG. 7). It has a length dimension s1 that can be cut at a length. The width dimension s2 of the nail decoration sheet 1 shown in FIGS. 2 (a) and 2 (c) is set in consideration of hand nails, toenails, gender, physique differences, and the like. For example, the dimension may be set to change at intervals of 0.1 to 0.3 mm, and may be set to suit various claws 3. On the other hand, the thickness dimension of the nail decoration sheet 1 shown in FIG. 2 (b) and FIG. 2 (c) is, for example, the thickness dimension s3 of the thickest portion in the center is about 0.5 mm to 1.5 mm. It becomes thinner as it goes to the peripheral part, and the thickness dimension s4 at the thinnest part of the peripheral part is about 0.1 mm to 0.3 mm.
These dimensions are examples, and are appropriately selected depending on the size of the nail, the sex of the person to be treated, the physique, and the like, and are not limited.

The nail decoration sheet 1 includes a clear one, a color one, a one designed by printing, and the like, and is provided with at least one of these. For example, there are a translucent design with color, a transparent design, a non-transparent design, and so on.
The colored opaque or colored transparent nail decoration sheet 1 can be colored (color) by adjusting and adding a pigment of pigment to the material before molding.

  The design of the nail decoration sheet 1 is printed on the urethane resin base constituting the nail decoration sheet 1 by printing such as ink jet or silk printing, and a urethane resin protective layer is formed thereon by potting or the like. Etc. This method is an example, and other methods may be used for design, and techniques other than printing may be employed.

Next, the procedure of the nail art treatment method using the nail decoration sheet 1 will be described with reference to FIG. FIG. 3 is a diagram showing a procedure of a nail art treatment method using the nail decoration sheet 1.
The nail art using the nail decoration sheet 1 will be described as an operation performed by the practitioner on the customer's nails 3 in a nail salon, for example.
First, oil and moisture on the nail 3 of the customer's finger 2 shown in FIG. 4 are removed by a cleanser or the like (S101 in FIG. 3). FIG. 4 is a perspective view showing the nail 3 of the finger 2 where the nail art of the first embodiment is performed.

Subsequently, as shown in FIG. 5, the base gel 4 containing liquid (water tank-like) urethane is applied to the nail surface 3h and the toe 3s (S102). FIG. 5 is a perspective view showing a state in which the base gel 4 is applied to the nail surface 3 h and the toe 3 s of the finger 2.
Subsequently, the base gel 4 applied to the nail surface 3h and the toe 3s is irradiated with light with a UV (ultraviolet) light (not shown) or the like to cure the applied base gel 4 (S103).
Subsequently, the uncured gel of the base gel 4 adhering to the nail surface 3h and the toe 3s is gently wiped with a sponge or the like (S104).

Then, as shown in FIG. 6, the nail decoration sheet 1 is placed on the nail 3 from the boundary between the cuticle 2 a and the nail 3, and is an uncured gel of the base gel 4 and / or an adhesive layer formed on the nail decoration sheet 1. Then, it is attached (attached) to the nail surface 3h (S105). FIG. 6 is a perspective view showing a state in which the nail decoration sheet 1 is stuck on the base gel 4 on the nail surface 3 h of the finger 2.
In S105, when the nail decoration sheet 1 is stuck on the nail 3 when the nail decoration sheet 1 is stuck, for example, when the nail 3 has a curve and the nail decoration sheet 1 is difficult to stick, the urethane resin is soft with heat. Therefore, it is preferable that the nail decoration sheet 1 is warmed with the heat of a dryer or heat of a heat light and softened before being attached (attached).
Subsequently, as shown in FIG. 7, a part or the whole of the nail decoration sheet 1 protruding from the nail surface 3h with the scissors 7 is cut (cut) (S106). FIG. 7 is a diagram illustrating a state in which a portion of the nail decoration sheet 1 protruding from the nail surface 3h is cut (cut).

Then, the finger 2 is put in an illumination area such as UV (ultraviolet) light (not shown), and the nail decoration sheet 1 and the base gel 4 on the nail 3 are irradiated with light and cured (S107).
Then, as shown in FIG. 8, the top gel 5 containing liquid (water tank-like) urethane is applied to the nail decoration sheet 1 and the toe 3s on the nail surface 3h (S108). FIG. 8 is a view showing a state in which the top gel 5 is applied to the nail decoration sheet 1 and the toe 3s on the nail surface 3h.

Then, the top gel 5 applied on the nail decoration sheet 1 on the nail 3 and on the toe 3s is irradiated with light with a UV (ultraviolet) light (not shown) or the like to be cured (S109).
Finally, the uncured gel of the top gel 5 on the nail decoration sheet 1 and the toe 3s is wiped off with a cleanser or the like which is an acetone-based liquid (S110).
Through the above process, nail art using one nail decoration sheet 1 shown in FIG. 1 is completed.

  In addition, although the case where the nail decoration sheet 1 was cut by the length substantially the same as the length of the nail | claw 3 was illustrated in S106, you may cut by the desired length different from the length of the nail | claw 3. Alternatively, the nail decoration sheet 1 may be substantially the same as the length of the nail 3, or the shape of the nail decoration sheet 1 may be adjusted, and the cut (cut) process in S106 may be omitted.

According to the nail decoration method of the first embodiment, the nail art treatment is simple and easy, and the conventional one-hour method takes about half the time of about 30 minutes. Therefore, the work efficiency of the nail salon can be improved and it can contribute to an increase in profit.
Furthermore, since a high point is formed in the nail decoration sheet 1 at the center, the shape after the art (treatment) is excellent in aesthetics, and it is possible to form a beautiful nail shape.

Further, since at least one of clear (transparent), color, or design is applied to the nail decoration sheet 1, the necessity for the practitioner to perform decoration manually is eliminated. For this reason, there is no difference in performance between the practitioner who is a senior or a beginner, and nail art with high leveled quality is possible.
As described above, since the nail decoration sheet 1 is previously decorated with pigments of pigment, printing, etc., various designs are possible, many arts can be provided, and the range of arts is expanded.

  In addition, if the material of the nail decoration sheet 1 includes a urethane acrylate oligomer urethane resin that does not inhibit transpiration, the transpiration of the nail 3 is not inhibited, so that the nail 3 does not feel breathless. Therefore, nail art can be performed which is good for health and does not harm health even if used for a long time.

Moreover, the nail art, which has conventionally been only for a short period of two weeks from one day, uses the base gel 4, the top gel 5, and the nail decoration sheet 1 containing urethane resin, so that the nail decoration sheet 1 can be applied to the nails 3. Adhesion is high and long-term maintenance (long-lasting for about 4 weeks) is possible.
Therefore, treatment at a nail salon or the like is easy and can be done in a short time, and high quality nail decoration (art) can be realized.

Subsequently, as shown in FIG. 16, the first nail decorative sheet 21A on the nail 3 is cut (cut) to an appropriate length with scissors 27 (the ee line two-dot chain line in FIG. 16) (S206). . FIG. 16 is a diagram illustrating a state in which the first nail decoration sheet 21A on the nail 3 is cut (cut).
Then, the finger 2 is put into a UV (ultraviolet) light (not shown) or the like, and the base gel 24 and the first nail decoration sheet 21A on the nail 3 are irradiated with light and cured (S207).

  Subsequently, as shown in FIG. 17, the second nail decoration sheet 21B is placed on the base gel 24 on the nail 3 from the boundary between the cuticle 2a and the nail 3, and on the first nail decoration sheet 21A. It is stuck (attached) by the adhesive layer formed on the lower surface of the 24 uncured gel or / and the second nail decoration sheet 21B (S208). FIG. 17 is a diagram illustrating a state in which the second nail decoration sheet 21B is attached (mounted) on the base gel 24 on the nail 3 and the first nail decoration sheet 21A.

  In S208, when the second nail decoration sheet 21B is stuck on the nail 3, when the second nail decoration sheet 21B is difficult to stick, for example, when the nail 3 has a curve and the second nail decoration sheet 21B is difficult to stick, Since the urethane resin becomes soft with heat, the second nail decoration sheet 21B is preferably warmed with the heat of a dryer or heat of the heat and softened before being attached (attached).

Then, as shown in FIG. 18, the scissors 27 are used to cut (cut) a part or the whole of the portion protruding from the side of the nail 3 (the gg two-dot chain line in FIG. 18) and the first and second The nail decoration sheets 21A and 21B are cut (cut) into a desired length (f-f two-dot chain line in FIG. 18) (S209). FIG. 18 is a diagram illustrating a state in which the side of the nail 3 and the first and second nail decoration sheets 21A and 21B are cut (cut).
Subsequently, as shown in FIG. 19, the top gel 25 containing liquid (water tank-like) urethane is applied to the second nail decoration sheet 21B and the toe 3s on the nail 3 (S210). FIG. 19 is a view showing a state in which the top gel 25 is applied to the second nail decoration sheet 21B on the nail 3 and the toe 3s.

Then, the top gel 25 on the second nail decoration sheet 21B attached (attached) to the nail 3 is irradiated with light such as UV (ultraviolet) light (not shown) and cured (S211).
Finally, the uncured gel of the top gel 25 remaining on the second nail decoration sheet 21B and the toe 3s is wiped off with a cleanser or the like which is an acetone-based liquid (S212).

According to the nail decoration method of the second embodiment, the first and second nail decoration sheets 21A and 21B are stacked on the nail 3 and cut (cut) to obtain a desired length. That is, since the superimposed first and second nail decoration sheets 21A and 21B can be cut (cut) with a desired length, the length of the nail art nail can be freely adjusted.
In addition, when the length is extended with one artificial nail, the first and second nail decoration sheets 21A and 21B are overlaid on the nail 3, but the desired length is too soft. Even so, it can be hard.

Conventionally, the artificial nail could not be shaped, but the first and second nail decoration sheets 21A and 21B have high points, respectively, so that the desired length of the nail is beautiful after the art. It can be shaped and has a beautiful appearance.
In addition, the nail art procedure is simple and easy, and the conventional one-hour procedure takes about half the time of about 30 minutes. Therefore, the work efficiency of the nail salon can be improved and it can contribute to an increase in profit.
In addition, since the first and second nail decoration sheets 21A and 21B are preliminarily provided with at least one of clear (transparent), color, or design, the necessity for the operator to perform decoration manually is eliminated. For this reason, there is no difference in performance between the practitioner who is a senior or a beginner, and nail art with high leveled quality is possible.

As described above, the first and second nail decorative sheets 21A and 21B are preliminarily decorated with pigments of pigments, printing, etc., so various free designs are possible, many art can be provided, and the width of the art Spread.
In addition, if the urethane resin of urethane acrylate oligomer is included in the material of the first and second nail decoration sheets 21A and 21B, the transpiration movement of the nail 3 is not inhibited, so that the nail 3 does not feel stuffy.

In addition, the nail art, which has conventionally been only for a short period of two weeks from one day, uses the base gel 24, the top gel 25, and the first and second nail decorative sheets 21A and 21B containing urethane resin, so that the first -The second nail decoration sheet 21A, 21B has high adhesion to the nail 3 and can be maintained for a long period (about 4 weeks). High nail art (nail decoration) can be realized.

In addition, although the said embodiment demonstrated and demonstrated the nail decoration sheet | seat which does not prevent the transpiration | movement of a nail | claw, what prevents the transpiration | transfer movement of a nail | claw with a urethane resin is also possible. For example, there is one in which a urethane resin is cast and processed on a seal. In this case, pores may be provided in the seal so as not to disturb the transpiration of the nail.
Or it is also possible to set it as the nail decoration sheet | seat using the material which does not prevent the transpiration | evaporation movement of nails other than urethane resin, or the material which prevents.
However, if a urethane resin is applied to the nail decoration sheet, the adhesive strength and durability to the nail 3 are strong, and it is difficult to peel off from the nail for a long time. In addition, if a urethane resin such as urethane acrylate oligomer that does not interfere with the transpiration of the nail is used, the nail 3 does not feel breathless. Therefore, it is most desirable to use a urethane resin that does not interfere with the transpiration movement.

In the above embodiment, the case where a base gel and a top gel containing a urethane resin are used as an example. However, as long as the compatibility with the nail decoration sheet is good and the adhesion to the nail of the nail decoration sheet is high. Base gel and top gel that do not contain urethane resin may be applied.
Moreover, in the said embodiment, the case where the nail decoration sheet | seat was shape | molded with the urethane resin which does not inhibit the transpiration | evaporation property of a nail | claw was illustrated, and the case where a base gel and a top gel apply what does not inhibit the transpiration | evaporation property of a nail | claw was illustrated. However, it is needless to say that when a nail decoration sheet that impairs the transpiration of the nail is applied, a base gel or top gel that obstructs the transpiration of the nail may be applied.

In addition, in the said embodiment, although the case where a nail decoration sheet was light-cured and stuck on a nail was illustrated, the nail decoration sheet is softened with heat and light-cured and pasted. It is also possible to apply other methods of curing and sticking (attaching), such as curing and sticking, pasting after hardening the nail decoration sheet, etc., the method of hardening and sticking (attaching) the nail decoration sheet is It is not limited.
In the above embodiment, the case where one or two nail decoration sheets are used between the base gel and the top gel is exemplified. However, three or more nail decoration sheets are used between the base gel and the top gel. It is good to do. In this case, at least one of the three or more nail decorative sheets is formed into a shape with a different thickness so that a high point is formed on the nail after the treatment, so that the nail after the art looks beautiful ( (Enhancing the beauty of nails after art).

However, as described above, when two nail decorative sheets are used, two sheets are desirable because sufficient hardness is obtained, work is easy, and a short time is required. In addition, it is preferable that the two nail decoration sheets are made of a solid material having flexibility and the center part is thicker than the peripheral part because the nail after art looks beautiful.
In the embodiment, the case where the nail decoration sheet is cut in the illustrated treatment is illustrated, but the nail decoration sheet is set to a predetermined size in advance, the nail decoration sheet suitable for the person to be treated is selected, and the nail is selected.
