Description

The present invention relates to a nail or artificial nail decoration method and a nail or artificial nail decoration tool used in this decoration method.

Conventionally, so-called nail art has been performed in which nail cosmetics such as nail polish are applied to the nail to decorate the nail.
Such nail art has recently been applied to sculptures (acrylic nails) that extend raw nails by applying acrylic resin to raw nails and nail foam attached to the tips of raw nails, and synthetic resin materials. It is also made on artificial nails such as nails.
In addition to planar patterns such as nail polish, three-dimensional art is performed to decorate the surface of nails or artificial nails by attaching a three-dimensional object or the like formed of rhinestones, beads, synthetic resin materials, or the like.

When adhering the rhinestones etc. to the surface of the nail or artificial nail as described above, apply an adhesive etc. on the back surface to adhere, or place the rhinestone etc. at the desired position on the surface of the nail or artificial nail It is necessary to fix the top coat by applying it on the surface, which is a troublesome work and requires a high level of technology to be mounted at a desired position.
In addition, since such a rhinestone has a flat back surface, when adhered to the surface of a nail or an artificial nail, the rhinestone protrudes greatly from the surface, and clothes or the like are easily caught on the rhinestone. Also, there was a problem that it was easy to peel off.
Furthermore, the rhinestones as described above have a flat back surface and a mirror surface layer attached to the bottom, which increases the brightness by reflection of the mirror surface layer. The mirror surface layer peeled off and could not be reused. Moreover, there was a problem that the brightness was inferior to jewelry cut into a polyhedron.

In the following Patent Document 1, a nail cosmetic containing a jewel is proposed in order to solve the above-described problems.
This nail cosmetic is composed of a transparent solvent containing a film forming agent containing a jewel, and the film forming agent is hardened on the nail by applying the transparent solvent to the nail surface with a brush or the like. It is explained that it can be fixed.
In this case, the jewel can be fixed on the nail relatively easily, but the jewel contained in the transparent solvent is a fine one that can be obtained with a brush or the like (0.0033 carat or more, 0.00. However, it is difficult to place and fix such a fine gemstone at a desired position with a brush or the like.

Moreover, in the following patent document 2, the manufacturing method of the artificial nail provided with the jewel is proposed.
In this artificial nail manufacturing method, a thickness adjustment layer is provided on the surface of the artificial nail substrate, an attachment recess for fitting diamond is formed in the thickness adjustment layer, and the translucency is obtained in a state solidified in the attachment recess. The adhesive is injected, and before the adhesive is solidified, the diamond is put into the attachment recess and bonded and fixed. Moreover, the said attachment recessed part is formed in the column shape made into the same magnitude | size from the upper surface of this thickness adjustment layer to a base material.

  However, in the method for manufacturing a false nail having a jewel described in Patent Document 2, the shape of the attachment recess into which the jewel is inserted by being injected with an adhesive is a cylindrical shape. When putting the jewel, the jewel may be inclined and the surface of the jewel may not be arranged parallel to the nail surface. In particular, when a jewel whose lower part has a substantially inverted conical shape is put into the attachment recess having a cylindrical shape as described above, it becomes unstable and the risk of tilting as described above increases. When the jewel is fixed in a tilted state as described above, there is a problem that the shine inherent in the jewel is lost and the appearance is deteriorated. Further, when the jewel is fixed by tilting in this way, the lower part of the jewel may be exposed on the nail surface side, and it may be caught on clothes or the like and may be easily peeled off.

By aligning with the circle center of the film and cutting using the circle as a guide, a mortar-shaped recess having the same shape and shape as the lower part of the gemstone of the predetermined size is formed, and an adhesive is formed in the recess. after coating, fitting the bottom of jewelry said predetermined size the recess Characterized in that it write adhesive.

In the nail or artificial nail decoration method of the present invention, the artificial nail may include a resin layer formed by curing a nail cosmetic mainly composed of a synthetic resin material .
Moreover, in the decoration method of the nail or the artificial nail of the present invention, the adhesive is an ultraviolet curable adhesive, and after the ultraviolet curable adhesive is applied to the recess, the lower part of the jewel is applied to the recess. The ultraviolet curable adhesive may be cured by fitting and irradiating ultraviolet rays with an ultraviolet irradiation device.

Further, in the decoration method of the nail or artificial nail of the present invention, the jewel of the predetermined size is composed of a plurality of jewels having substantially the same shape and different sizes, and the positioning film is adapted to the plurality of jewels, It is good also as what consists of several sheets formed, respectively . Alternatively, in the nail or artificial nail decoration method of the present invention, the predetermined size jewel is composed of a plurality of jewels having substantially the same shape and different sizes, and the positioning film is adapted to the plurality of jewels, a plurality of said circles and the circle of circle center may be assumed that consists of a piece drawn.

In order to achieve the above object, a nail or artificial nail decoration tool according to the present invention is a nail or artificial nail decoration tool used in any of the nail or artificial nail decoration methods, and has the predetermined size. A circle having the same diameter as the outer peripheral diameter of the upper peripheral edge of the lower part of the jewel and a circle center of the circle are drawn, and the nail or artificial nail sticking film to be stuck to the nail or artificial nail, and the predetermined A nail or an artificial nail rotary cutting tool having a substantially inverted conical cutting portion that is substantially the same shape as the lower part of the jewel of the size and at least larger than the lower part of the jewel of the predetermined size. It is characterized by that.

Further, in the nail or artificial nail decoration method of the present invention, a cutting portion in which a positioning line is formed on the outer periphery of the cutting portion in accordance with the depth of the lower portion of the gemstone of the predetermined size, the positioning line and the The recess may be formed by cutting with reference to the circle of the positioning film.
In order to achieve the above object, a nail or artificial nail decoration tool according to the present invention is a nail or artificial nail decoration tool used in the above-described nail or artificial nail decoration method, and is a lower part of the jewel of the predetermined size.

On the outer periphery, a positioning line is formed at a position corresponding to the depth of the lower part of the jewel of the predetermined size.

Alternatively, in the nail or artificial nail decoration method of the present invention, cutting is performed in a state in which a regulating member that is formed according to the depth of the lower part of the jewel of the predetermined size and is detachable is attached to the cutting portion. Thus, the depth of the concave portion may be regulated by the regulating member to form the concave portion.
In order to achieve the above object, a nail or artificial nail decoration tool according to the present invention is a nail or artificial nail decoration tool used in the above-described nail or artificial nail decoration method, and is a lower part of the jewel of the predetermined size. A circle having substantially the same diameter as the outer peripheral diameter of the upper peripheral edge of the lip, and a circle center of the circle, and a nail or artificial nail sticking film to be stuck to the nail or artificial nail, and a jewel of the predetermined size A nail or a rotary cutting tool for artificial nail having a substantially inverted conical cutting part that is substantially the same shape as the lower part of the jewel and at least larger than the lower part of the jewel of the predetermined size. Is formed in accordance with the depth of the lower portion of the predetermined-sized jewel, and a regulating member for regulating the depth of the concave portion is detachably attached.

According to the decoration method of the nail or artificial nail according to the present invention, an adhesive is applied to a mortar-shaped recess formed in accordance with the shape of the lower part of a jewel whose lower part has a substantially inverted conical shape, Since the lower part of the jewel is fitted and bonded to the recess, the jewel can be fixed to the nail or the artificial nail with certainty and good appearance.
That is, since the concave portion for fitting the jewel is formed in accordance with the shape of the lower portion of the jewel, when the jewel is fitted into the concave portion, the jewel is not tilted and securely fitted. It looks nice and can be attached to the nail or artificial nail. That is, the lower part of the jewel is not exposed to the nail surface side, and therefore, it is not easily caught on clothes or peeled off. Further, since the jewel is not tilted and fitted, the shine inherent in the jewel is not impaired.
Furthermore, since the recess for fitting the jewel is formed according to the shape of the lower part of the jewel, an unnecessary gap or the like does not occur between the lower part of the jewel and the formed recess.

  In the decoration method of the nail or artificial nail according to the present invention, if the object to be formed of the recess is a resin layer formed by applying a nail cosmetic mainly composed of a synthetic resin material to the nail or artificial nail, By adjusting the thickness of the resin layer according to the size of the jewel and forming the recess, it is possible to fit the lower part of the relatively large jewel into the recess.

  In the nail or artificial nail decoration method according to the present invention, if the rotary cutting tool has a cutting portion having a substantially inverted conical shape substantially the same shape as the lower part of the jewel, A concave portion matching the shape of the lower portion can be easily formed. That is, if the cutting part is pressed perpendicularly to the surface of the nail or the artificial nail and the depth is adjusted and the cutting is performed, the concave part matching the shape of the lower part of the gemstone is surely and easily obtained. Can be formed.

In the nail or artificial nail decoration method according to the present invention, before the recess is formed by the rotary cutting tool, the nail or the artificial nail is substantially the same diameter as the outer peripheral diameter of the upper peripheral edge of the lower part of the jewel. If the positioning film on which the circle and the center of the circle are drawn are attached and the rotary cutting tool is aligned with the positioning film to form the recess, the positioning film Therefore, it is possible to reliably and easily form a recess that matches the shape of the lower part of the gemstone. That is, the concave portion can be easily formed by aligning the tip of the rotary cutting tool with the center of the positioning film and cutting the inside of the circle while adjusting the depth.
In addition, for example, by attaching a plurality of the above positioning films to a desired position on the surface of a nail or an artificial nail which is a narrow art space, it is possible to easily position a position where a gem is to be attached and a finished state Can be predicted.
In particular, when jewelry of different sizes are attached to nails or artificial nails, it is difficult to predict the final state and form a recess at a desired position, for example, closer to or away from each other than the desired position. There is a possibility that a plurality of recesses may be formed at the position, but by preparing the positioning film according to gems of different sizes and sticking to a desired position, the finished state can be predicted, A concave portion matched to the shape of the lower part of the jewel can be formed reliably and easily.

In the nail or artificial nail decoration method according to the present invention, the adhesive is an ultraviolet curable adhesive, and after applying the ultraviolet curable adhesive to the recess, the lower part of the jewel is fitted into the recess, When the ultraviolet curable adhesive is cured by irradiating ultraviolet rays with an ultraviolet irradiating device, for example, there is no off-flavor such as a quick-drying adhesive containing a volatile substance, and natural drying. It can be cured relatively quickly and reliably compared to an adhesive or the like that is cured by the above.
Moreover, since it does not harden | cure until it irradiates with an ultraviolet-ray, when the lower part of a jewel is engage | inserted in a recessed part, final alignment can be performed and this jewel can be attached to a nail | claw or an artificial nail reliably and attractively.

Moreover, according to the said nail | claw or artificial nail sticking film with which the said nail | claw or artificial nail decoration tool which concerns on this invention is equipped, the circle | round | yen made into the substantially same diameter as the outer peripheral diameter of the upper end peripheral part of the lower part of the said jewel, and this circle | round | yen When the mortar-shaped concave portion matching the shape of the lower part of the jewel is formed on the nail or the artificial nail with the rotary cutting tool, the nail or the artificial nail sticking film is attached to the nail or the artificial nail. By sticking to an artificial nail, the sticking film serves as a standard, and a concave portion matching the shape of the lower part of the jewel can be reliably and easily formed. Moreover, by sticking the nail or the artificial nail sticking film to the nail or the artificial nail, it is possible to easily position the position where the jewel is to be attached and to predict the finished state.

Further, according to the nail or artificial nail rotary cutting tool provided in the nail or artificial nail decoration device according to the present invention, the cutting part is formed in a substantially inverted conical shape substantially the same shape as the lower part of the jewel. Therefore, when the concave portion is formed in the nail or the artificial nail for attaching the gemstone to the nail or the artificial nail, the concave portion matching the shape of the lower portion of the gemstone can be easily formed. That is, if the cutting part is pressed perpendicularly to the surface of the nail or the artificial nail and the depth is adjusted and the cutting is performed, the concave part matching the shape of the lower part of the gemstone is surely and easily obtained. Can be formed.

In the nail or artificial nail rotary cutting tool provided in the nail or artificial nail decoration tool according to the present invention, an outer periphery of the cutting portion is formed at a lower portion of each of the plurality of jewels having substantially the same shape and different sizes. If a positioning line is formed at a position that matches the depth, a tool that can easily form a recess that matches the size of the gemstone can be obtained. That is, since the concave portion can be formed with the positioning line as a guide, the tool can be reduced from making the concave portion too deep or too large.

In the nail or artificial nail rotary cutting tool provided in the nail or artificial nail decoration tool according to the present invention, the depth of the concave portion is regulated in the cutting portion according to the depth of the lower part of the jewel. If the restricting member is provided, it is possible to effectively prevent the concave portion from being formed too deeply or excessively, and the concave portion adapted to the shape of the lower part of the jewel can be more reliably and securely formed. Can be easily formed. Moreover, since it can prevent forming a recessed part too deeply, it becomes an excellent tool also in terms of safety.

Further, if the claw or artificial nail rotary cutting tool provided in the nail or artificial nail decoration device according to the present invention is detachably attached to the head part of the rotary handpiece, the shape of the lower part of the jewel is the same as above. Therefore, the handpiece can be surely and easily formed with the concave portion matched to the above.

FIGS. 11A to 11D are schematic front views showing an example of a rotary handpiece device used in the decoration method.

  The artificial nail 1 decorated using the nail or artificial nail decoration method according to the present embodiment forms a resin layer 10 on the self-nail N of the finger F, and is a rotary type attached to the rotary handpiece device 8. By using the cutting tool 3 (see FIG. 9B and FIG. 10), the concave portion 4 is formed in the resin layer 10, and the lower portion 21 of the jewel 2 (see FIG. 9A) is fitted into the concave portion 4, and the adhesive 5 Glued and attached. Moreover, in this embodiment, before forming the recessed part 4 so that it may mention later, the positioning film 6 (refer FIG.3 and FIG.11) is stuck. The adhesive 5 is an ultraviolet curable adhesive and is cured by the ultraviolet irradiation device 7 (see FIG. 5B).

First, the above-described members and devices used in the decoration method will be described with reference to the drawings.
The resin layer 10 includes a colorless and transparent acrylic layer 11 mainly composed of an acrylic resin material formed on the nail N, a pattern layer 12 formed on the acrylic layer 11, and the pattern layer 12 And a transparent layer 13 formed thereon.
The acrylic layer 11 is a so-called sculpture (also referred to as acrylic nail) in which acrylic liquid, which is a nail cosmetic, and acrylic powder are mixed and cured. The acrylic layer 11 is formed so as to extend the nail so as to extend from the tip of the nail N.
The acrylic liquid is made of, for example, methyl methacrylate and a catalyst agent, and the acrylic powder is made of, for example, polymethyl methacrylate and a polymerization initiator. When the catalyst agent and the polymerization initiator are mixed, heat is generated, and the catalyst agent is gelled and cured.
In addition, as long as it has translucency when cured, it is not limited to the colorless and transparent acrylic layer 11, but a color powder in which a colorant or the like is added to the acrylic powder, and a milky white or pink acrylic layer 11 may be used. Good.
Further, when the acrylic layer 11 is formed, the acrylic layer is applied by a thickness check member having a stick-like scale or the like in an uncured (semi-cured) state after applying the mixture (mixture). Eleventh thickness may be checked. Thereby, it can be set as the thickness according to the magnitude | size of the jewelry to attach, and safety can be improved.

The pattern layer 12 is formed of a gel-like (gel-like) UV curable nail cosmetic (so-called soft gel) containing a urethane resin material as a main material and containing a photoinitiator, a colorant, and the like.
The transparent layer 13 is formed of a gel-like (gel-like) ultraviolet curable nail cosmetic (so-called hard gel) containing an acrylic resin material as a main material and containing a photoinitiator or the like.
The pattern layer 12 is relatively soft, and the transparent layer 13 is relatively hard.
The acrylic layer 11 and the pattern layer 12 are so-called soak-off types that can be removed with a removal solvent (remover) such as acetone, and the transparent layer 13 is a so-called soak-off-free type that can be removed by scraping with a file (file) or the like. It is said that. The transparent layer 13 may be a soak-off type.

Further, the resin layer 10 is not limited to the above example, and any resin material can be used as long as it can be formed with a predetermined thickness so as to extend from the surface of the nail N and the tip of the nail. You may make it form.
Further, the thickness of the resin layer 10 may be adjusted according to the size of the diamond 2 described later. When the relatively small diamond 2 is attached, the color soft gel or the clear is used instead of the acrylic layer 11. The resin layer may be formed by repeatedly applying hard gel or the like. The thickness of the resin layer 10 is preferably about 5.00 mm or less because it looks bad if it is too thick.
Moreover, in each figure, although the thickness of the said resin layer 10 is shown with the substantially same thickness toward the back end side from the front-end | tip of the said resin layer 10, for example, a center part is thick and a front-end | tip part is thin. You may make it do. That is, the thickness of the resin layer 10 may not be uniform in the plane area direction.
Further, instead of the pattern layer 12, a pattern may be formed by a paint such as nail polish (nail enamel, nail color), or a top coat may be formed on the pattern layer 12 instead of the clear hard gel. You may make it apply | coat to.
Further, the resin layer 10 may be constituted only by the acrylic layer 11.

The jewel 2 is a diamond 2 in the present embodiment. As shown in FIG. 9A, the diamond 2 is formed by being cut into a polyhedron, and includes an upper crown portion 20, a lower pavilion portion 21, and a boundary between the crown portion 20 and the pavilion portion 21. And a girdle portion 22 forming the same.
The crown portion 20 has a substantially truncated cone shape and has a table surface 20a having a flat upper surface.
The pavilion portion 21 has a substantially inverted conical shape that is tapered toward the curette 21a at the lower end. In addition, since the shape of the pavilion part 21 is cut into a polyhedron, it is actually a substantially inverted polygonal cone shape or a shape close thereto, but such a shape is also included in a substantially inverted cone shape. In other words, the pavilion portion 21 having a substantially inverted conical shape includes a shape in which the outer shape of a rotating body rotated about a perpendicular line passing through the curette 21a at the lower end portion becomes a substantially inverted conical shape.
The girdle part 22 constitutes the upper peripheral edge of the pavilion part 21 and forms the outer peripheral edge of the diamond 2, and the outer peripheral diameter Gd of the girdle part 22 corresponds to the diameter of the diamond 2. Since the girdle part 22 is generally relatively thin, the depth Pd of the pavilion part 21 described later includes the thickness of the girdle part 22 in this embodiment.

In the illustrated example, a so-called standard round brilliant cut diamond 2 is shown, and the pavilion angle θ1 of the diamond 2 is about 40 °. Therefore, the angle (Curet angle) θ2 in the front view of the lower end portion of the pavilion portion 21 is about 100 °.
The size of the diamond 2 used in the nail or artificial nail decoration method according to this embodiment is preferably 0.005 carats or more and 1.00 carats or less. In terms of the outer peripheral diameter (diameter of diamond 2) Gd of the girdle part 22, it is preferable to set it to about 1.00 mm or more and about 6.50 mm or less. If it is smaller than this, it is difficult to attach to the artificial nail 1 and the splendor due to the attachment of the gemstone is inconspicuous. If it is larger than the above, it is necessary to form the resin layer 10 thick, and on the artificial nail 1 which is a narrow art space, the balance is poor and the appearance is poor.
In a standard round brilliant cut, when the outer peripheral diameter Gd of the girdle part 22 is in the above range, the depth Pd of the pavilion part 21 is about 0.43 mm to about 2.80 mm.

The gemstone to be attached to the artificial nail 1 is not limited to the diamond 2, but other light-transmitting natural stones such as aquamarine, amethyst, emerald, sapphire, topaz, ruby, and artificial stones such as cubic zirconia, In addition, artificial stones such as synthetic stones and imitation stones may be used.
Moreover, as long as it is cut into a polyhedron and the lower part has a substantially inverted conical shape, it is not limited to the round brilliant cut and may be cut in any way. For example, the upper part (crown part) may have a heart shape, a square shape, or another shape in plan view.
Furthermore, the pavilion angle and the culet angle are angles in the case of a standard round brilliant cut, and may be other angles.

As shown in FIG. 9B, the rotary cutting tool 3 includes a shaft portion 30 attached to a head portion 81 of a rotary handpiece 80 to be described later, and a cutting formed on the tip portion of the shaft portion 30. A portion 31, a columnar portion 32 continuously provided on the shaft portion side of the cutting portion 31, and a truncated cone portion 33 continuously provided on the shaft portion side of the columnar portion 32.
The cutting portion 31 has a substantially inverted conical shape that is substantially the same shape as the pavilion portion 21 of the diamond 2. That is, the angle in the front view of the lower end portion of the cutting portion 31 is the same as the angle θ2 in the front view of the lower end portion of the pavilion portion 21.
Thus, when the recessed part 4 is formed in the artificial nail 1 as will be described later, the pavilion of the diamond 2 is formed by making the cutting part 31 into a substantially inverted conical shape substantially the same shape as the pavilion part 21 of the diamond 2. This is a tool that can easily form the concave portion 4 in accordance with the shape of the portion 21. That is, if the cutting portion 31 is pressed perpendicularly to the surface of the artificial nail 1 and the cutting is performed while adjusting the depth, the concave portion 4 matched to the shape of the pavilion portion 21 of the diamond 2 is surely obtained. And can be formed easily.

The height Ch of the cutting portion 31 can be appropriately set according to the size of the diamond 2 to be attached. For example, when a diamond 2 of 1.00 carat or less is desired to be attached, the height Ch is about 3.00 mm. It should be the height of.
Further, the cutting part 31 may be anything as long as it can form the recess 4 as will be described later on the resin layer 10. For example, the cutting part 31 may have a drill blade shape or abrasive grains as a binder. Any of a grindstone system hardened with a diamond, a diamond grindstone system in which industrial diamond abrasive grains are electrodeposited and fixed on a shaft (shaft), a high speed cutter system, etc. may be used. This cutting part 31 is good also as what does not generate | occur | produce a heat | fever easily at the time of cutting so that there may be no heat influence to the own nail | Nail, when forming the recessed part 4 in the artificial nail | claw 1.
Further, in the substantially inverted conical shape of the cutting portion 31, the outer shape of the rotating body obtained by rotating the cutting portion 31 about the shaft portion 30 as the rotation axis is substantially inverted conical, similar to the shape of the pavilion portion 21 of the diamond 2. Including those that become.
Furthermore, the cutting portion 31 may be a substantially inverted conical shape that is substantially the same shape as the pavilion portion 21 of the diamond 2, and the other shapes are not limited to those shown in the drawings.

The rotary cutting tool 3 is mounted on a rotary handpiece device 8 as shown in FIG.
The rotary handpiece device 8 includes a rotary handpiece 80 and a device main body 85 connected to the rotary handpiece 80 by a cord 84.
The rotary handpiece 80 is a so-called micromotor-type handpiece, and includes a gripping portion 82 having a built-in micromotor 83 serving as a driving source and a front side of the gripping portion 82, and a driving body. The drive body is provided with a chuck portion 81a for detachably mounting the rotary cutting tool 3 thereon. The driving body may be anything as long as it is connected to a driving source, and may include a rotating shaft and a bearing portion that supports the rotating shaft.

As shown in FIGS. 3 and 11, the positioning film 6 is a film made of a thin resin, paper, fiber, etc., and the back surface thereof is coated with an adhesive, and a mount (not shown) or the like. And is attached to a desired position on the surface of the artificial nail 1.
As shown in FIGS. 11A to 11C, the positioning film 6 includes circles 62, 60, and 63 that are substantially the same diameter as the outer peripheral diameter Gd of the girdle portion 22 of the diamond 2, and the circles of these circles. Hearts 62a, 60a, 63a are depicted.
Thus, the positioning film 6 is drawn with the circles 62, 60, 63 having the same diameter as the outer diameter Gd of the girdle portion 22 of the diamond 2 and the centers 62a, 60a, 63a of these circles. Therefore, as will be described later, when the mortar-shaped concave portion 4 that matches the shape of the pavilion portion 21 of the diamond 2 is formed on the artificial nail 1 by the rotary cutting tool 3, the positioning film 6 serves as a guideline. The concave portion 4 matched to the shape of the pavilion portion 21 can be reliably and easily formed. Further, by sticking the positioning film 6 to the artificial nail 1, it is possible to easily position the position where the diamond 2 is to be attached and to predict the finished state.

FIG. 11A shows a positioning film 6C on which a circle 62 having a diameter substantially equal to the outer peripheral diameter Gd1 of the girdle portion 22 of the relatively small diamond 2C is shown. In FIG. FIG. 11C shows a positioning film 6A on which a circle 60 having a diameter substantially the same as the outer peripheral diameter Gd2 of the girdle portion 22 of the diamond 2A is shown. FIG. 11C shows the outer periphery of the girdle portion 22 of the relatively large diamond 2E. A positioning film 6E on which a circle 63 having a diameter substantially the same as the diameter Gd3 is depicted. That is, a plurality of positioning films 6 are formed in accordance with the sizes of the diamonds 2C, 2A, and 2E having different sizes. In this way, by preparing a plurality of positioning films 6 formed in accordance with the size of the diamond 2, the recesses 4 for attaching a plurality of diamonds 2 having different sizes can be easily formed, and depending on the taste. By sticking to the desired position, the finished state can be predicted.
Further, FIG. 11D shows a positioning film 6D formed in a nail shape in advance. The positioning film 6D includes a plurality of circles 60, 61, 62 having different sizes and the centers of these circles. 60a, 61a, 62a are drawn. Thus, handling property is good by setting it as the single nail-shaped positioning film 6D.

In addition, the shape of the positioning film 6 is not limited to the illustrated example, and may be any shape. Moreover, it is good also as a film by which the several circle | round | yen and the circle center were drawn on the film of 1 sheet, without forming into a nail | claw shape like FIG.
In addition, the circle drawn on the positioning film 6 takes into account the thickness of the adhesive layer rather than the diameter Gd of the girdle portion 22 of the diamond 2 into which the recess 4 is formed and the adhesive 5 is applied as will be described later. Then, the diameter may be made slightly larger.

Next, the decoration method of the nail | claw or artificial nail | claw which concerns on this embodiment is demonstrated based on FIGS.
First, as shown in FIG. 2A, the acrylic layer 11 is formed on the self nail N of the finger F.
As described above, the acrylic layer 11 is formed by appropriately extending from the upper surface of the own nail N and the tip of the own nail N.
When the acrylic layer 11 is formed, the surface of the nail N is filed with a file or the like and applied with a primer agent or the like in order to reliably fix the acrylic layer 11. It may be. Alternatively, the acrylic layer 11 may be formed after applying the above-described soft gel or hard gel without applying the filing and primer agent. Moreover, in order to extend and form from the front-end | tip of the nail | claw N, you may make it form by attaching a nail form etc. to a front-end | tip part.

Next, as shown in FIG. 2B, the pattern layer 12 is formed on the upper surface of the acrylic layer 11.
Since the pattern layer 12 is a color soft gel that is cured by ultraviolet rays as described above, it is cured by the ultraviolet irradiation device 7 (see FIG. 5B) after application. In addition, you may make it wipe off the uncured part of the surface with ethanol etc.
Next, as shown in FIG. 2C, a transparent layer 13 is formed on the upper surface of the pattern layer 12.
Since the transparent layer 13 is also an ultraviolet curable clear hard gel like the pattern layer 12, after application, the transparent layer 13 is cured with an ultraviolet irradiation device 7 and the uncured portion of the surface is wiped off with ethanol or the like. Good.
Thereby, the resin layer 10 is formed.
As described above, by forming the hard transparent layer 13 on the soft pattern layer 12, as will be described later, the surface side peripheral portion of the recess 4 can be sharply formed when the recess 4 is formed.
Further, as described above, by forming the pattern layer 12 before forming the recess 4, the pattern layer is formed after the recess 4 is formed or after the diamond 2 is attached to the recess 4. Compared with workability.

Next, as shown in FIG. 3A, a positioning film 6 corresponding to the size of the diamond 2 to be attached is attached to a desired position on the upper surface of the artificial nail 1. In FIG. 3A, an example in which positioning films 6A, 6B, and 6C on which three types of circles 60, 61, and 62 having different sizes and the circle centers 60a, 61a, and 62a of these circles are drawn are attached. Is shown.
Next, as shown in FIG. 3B, the tip of the cutting part 31 of the rotary cutting tool 3 is aligned with the center 60a of the positioning film 6A and cut. At this time, cutting is performed until the circumferential surface of the cutting portion 31 reaches the circle 60 drawn on the positioning film 6A. Similarly, the portion where the other positioning films 6B and 6C are attached is cut.

By cutting with the rotary cutting tool 3 as described above, the recess 4 is formed in the resin layer 10 as shown in FIGS. The recess 4 has a mortar shape substantially the same shape as the pavilion portion 21 of the diamond 2. That is, the depth from the surface side peripheral portion of the concave portion 4 to the bottom portion of the concave portion 4 is substantially the same as the depth Pd of the pavilion portion 21 of the diamond 2, and the diameter of the upper peripheral edge of the concave portion 4 is the diamond 2. The girdle portion 22 has a mortar shape substantially the same diameter as the outer peripheral diameter Gd.
In the present embodiment, the concave portion 4A formed in accordance with the shape of the pavilion portion 21 of the relatively large diamond 2A (see FIG. 1), and the pavilion portion 21 of the diamond 2B (see FIG. 1) having a medium size. An example is shown in which a recess 4B formed to match the shape of and a recess 4C formed to match the shape of the pavilion portion 21 of a relatively small-diameter diamond 2C (see FIG. 1) is shown.
Note that blank portions of the positioning films 6A, 6B, and 6C may be wiped off with ethanol or the like after the recesses 4 are formed.

As shown in FIG. 5A, the ultraviolet curable adhesive 5 is applied to the recess 4 formed as described above, and the pavilion portion 21 of the diamond 2 is fitted. In this state, the pavilion portion 21 of the diamond 2 is buried in the recess 4 and the crown portion 20 is exposed on the surface side of the artificial nail 1.
Next, as shown in FIG. 5B, ultraviolet rays are irradiated by the ultraviolet irradiation device 7 to cure the ultraviolet curable adhesive 5, and the diamond 2 is completely fixed to the concave portion 4 of the artificial nail 1. Since the diamond 2 is translucent, the ultraviolet rays irradiated from the ultraviolet irradiation device 7 are transmitted, and the ultraviolet curable adhesive 5 can be reliably cured.

Through the above steps, a plurality of diamonds 2A, 2B, 2C are attached to the artificial nail 1 as shown in FIG.
Note that after curing, the uncured ultraviolet curable adhesive 5 remaining on the surface side may be wiped off with ethanol or the like.
Further, after the diamond 2 is fixed as described above, a top coat, a clear coat or the like may be applied to the entire upper surface of the artificial nail 1. Thereby, the diamond 2 can be more strongly fixed.
Further, when the artificial nail 1 decorated as described above and the diamond 2 attached to the artificial nail 1 are removed, the transparent layer 13 is removed by scraping with a file or the like, and the artificial nail is removed by using a solvent such as acetone. The artificial nail 1 and the diamond 2 may be removed by immersing and softening the nail 1. As described above, according to the nail or artificial nail decoration method according to this embodiment, the diamond 2 can be easily removed from the artificial nail 1 and can be reused.

As mentioned above, according to the decoration method of the nail | claw or artificial nail | claw which concerns on this embodiment, the lower pavilion part 21 is formed in the shape of the mortar shape formed according to the shape of the pavilion part 21 of the diamond 2 made into the substantially inverted cone shape. Since the UV curable adhesive 5 is applied to the concave portion 4 and the pavilion portion 21 of the diamond 2 is fitted and bonded to the concave portion 4, the diamond 2 can be fixed to the artificial nail 1 with certainty and good appearance. it can.
That is, since the concave portion 4 for fitting the diamond 2 is formed in accordance with the shape of the pavilion portion 21 of the diamond 2, when the diamond 2 is fitted into the concave portion 4, the diamond 2 is inclined and fitted. It is possible to attach the diamond 2 to the artificial nail 1 without fail. Therefore, the pavilion portion 21 of the diamond 2 is not exposed on the surface side and is not caught on clothes or the like, and is not easily peeled off. Moreover, since the table surface 20a of the diamond 2 is attached so as to be substantially parallel to the surface near the portion to which the artificial nail 1 is attached, the brightness inherent to the diamond 2 can be maximized.
Further, since the recess 4 for fitting the diamond 2 is formed in accordance with the shape of the pavilion portion 21 of the diamond 2, an unnecessary gap between the pavilion portion 21 of the diamond 2 and the formed recess 4 or the like Will not occur.

Furthermore, in this embodiment, since the recessed part 4 is formed in the resin layer 10 formed by applying cosmetics for nails mainly made of a synthetic resin material to the own nail N, the thickness of the resin layer 10 Can be adjusted according to the size of the diamond 2 (depth of the pavilion portion 21 and the adhesive layer), and the recess 4 can be formed to fit the pavilion 21 of the relatively large diamond 2 into the recess 4. It becomes.
Moreover, in this embodiment, since the said recessed part 4 is formed with the rotary cutting tool 3 which has the substantially inverted conical cutting part 31 made into the substantially same shape as the pavilion part 21 of the diamond 2, The recessed part 4 matched with the shape of the pavilion part 21 of the diamond 2 can be easily formed. That is, the concave portion 4 matched to the shape of the pavilion portion 21 of the diamond 2 can be obtained by pressing the cutting portion 31 perpendicularly to the surface of the artificial nail 1 and cutting while adjusting the depth. It can be reliably and easily formed.

  Furthermore, in the present embodiment, before forming the concave portion 4, the circle 60, which is substantially the same diameter as the outer peripheral diameter Gd of the girdle portion 22 of the diamond 2 having a different size, is formed at a desired position on the surface of the artificial nail 1. 61, 62 and positioning films 6A, 6B, 6C on which the circle centers 60a, 61a, 62a are drawn are attached, and the rotary cutting tool 3 is aligned with the positioning film 6 to form the recess 4. Therefore, the positioning film 6 serves as a guide, and the concave portion 4 that matches the shape of the pavilion portion 21 of the diamond 2 can be more reliably and easily formed. That is, it is easy by aligning the tip of the rotary cutting tool 3 with the circular centers 60a, 61a, 62a of the positioning film 6 and cutting the inside of the circles 60, 61, 62 while adjusting the depth. A mortar-shaped recess 4 having substantially the same shape as the pavilion 21 can be formed.

Also, by positioning a plurality of positioning films 6A, 6B, 6C as described above at a desired position on the surface of the artificial nail 1 that is a narrow art space, it is easy to position the position where the diamond 2 is to be attached. And can predict the finished state.
In particular, when the diamonds 2A, 2B, and 2C having different sizes are attached to the artificial nail 1 as in this embodiment, it is difficult to predict the completed state and form the recess 4 at a desired position. For example, there is a possibility that a plurality of recesses may be formed at positions closer to or away from each other than a desired position. However, a plurality of positioning films 6 may be formed as described above according to diamonds 2 having different sizes. By preparing and sticking to a desired position, the finished state can be predicted, and the recess 4 matched to the shape of the pavilion part 21 of the diamond 2 can be reliably and easily formed.
Further, in order to form a positioning mark, the mounting mark or the like on which a hole having a diameter substantially equal to the girdle diameter of the diamond 2 is applied to the surface of the artificial nail 1 and traced with a pencil or the like. However, it is a complicated operation. According to this embodiment, it is easy to position the position where the diamond 2 is to be attached by simply sticking the seal-like (sticker-like) positioning films 6A, 6B, 6C as described above, and workability is improved. .

Moreover, in this embodiment, since the adhesive is the ultraviolet curable adhesive 5, for example, there is no off-flavor such as a quick-drying adhesive containing a volatile substance, and the adhesive is cured by natural drying. It can be cured relatively quickly and reliably compared to an adhesive or the like.
Moreover, since it does not harden | cure until it irradiates with an ultraviolet-ray, when the pavilion part 21 of the diamond 2 is engage | inserted in the recessed part 4, final alignment can be performed and the diamond 2 can be attached to the artificial nail 1 reliably and attractively. it can.

In the present embodiment, after the positioning film 6 is adhered, the example in which the concave portion 4 is formed by the rotary cutting tool 3 in which the cutting portion 31 has substantially the same shape as the pavilion portion 21 of the diamond 2 is shown. Not only this but the angle (theta) 2 of the lower end part in the front view of a cutting part may be formed with the rotary cutting tool made into an acute angle rather than the said cutting part 31. FIG. Even with such a cutting tool, the tip portion is aligned with the center of the positioning film 6 and the depth is adjusted while cutting along the drawn circle to easily form the mortar-shaped recess 4. it can.
Moreover, you may make it form the recessed part 4 while adjusting the cutting depth with the said rotary cutting tool 3, without sticking the positioning film 6. FIG. Or you may make it form the mortar-shaped recessed part 4 with the above-mentioned cutting tool made into another shape, without sticking the positioning film 6. FIG. In such a case, the concave portion 4 may be formed gradually, and the diamond 2 to be attached may be fitted and formed while confirming the shape.
Furthermore, in this embodiment, the example in which the diamond 2 is attached to the artificial nail 1 of the finger F and decorated is shown. However, the resin layer 10 is formed on the toe nail, the recess 4 is formed, and the diamond 2 is attached. It is also possible.

Next, another example of the nail or artificial nail decoration method according to this embodiment will be described with reference to FIGS.
In addition, about the structure and process similar to an above-described example, the same code | symbol is attached | subjected and description is abbreviate | omitted or demonstrated easily.
In the example shown in FIG. 6A, the shape of the recess 4D is different from the above example. That is, in this modification, the recess 4D is formed to be slightly larger than the pavilion portion 21 of the diamond 2 to be attached, and the recess 4D is formed so that a part of the crown portion 20 is buried in the recess 4D.

In the example shown in FIG. 6B, the recess 4E is formed to be slightly larger than the recess 4D so that the table surface 20a of the crown portion 20 and the surface of the artificial nail 1 are substantially flush. The recess 4E is formed.
As described above, each of the recesses 4D and 4E is formed in a mortar shape in accordance with the shape of the pavilion portion 21 of the diamond 2, but by forming it slightly larger, an ultraviolet curable adhesive is formed on the peripheral surface of the crown portion 20. 5 is formed, and the diamond 2 is firmly and securely fixed.

Further, in the example shown in FIG. 7A, the recess 4F is formed in the extending portion of the artificial nail 1A, and the recess 4F is formed so as to penetrate the resin layer 10A of the artificial nail 1A. ing. That is, in a state where the diamond 2 is fitted and attached to the recess 4F, the lower end portion of the pavilion portion 21 of the diamond 2 is configured to protrude from the back surface of the artificial nail 1A.
Even in such a configuration, the concave portion 4F formed in the resin layer 10A has a mortar shape that matches the shape of the pavilion portion 21 of the diamond 2, so that the diamond 2 can be attached with certainty and good appearance. Further, since the recess 4F is formed by penetrating the acrylic layer 11A of the resin layer 10A, the acrylic layer 11A and the resin layer 10A can be formed thin.

Further, in the example shown in FIG. 7B, an example is shown in which the resin layer 10 as described above is not formed on the own nail N, and the recess 4 </ b> G is formed directly on the own nail N. In this case, the recess 4G may be formed so as to penetrate the extended portion of the nail N, that is, the nail plate portion not in contact with the nail bed.
In this example, similarly to FIG. 7A, the lower end portion of the pavilion portion 21 of the diamond 2 protrudes from the back surface of the nail N when the diamond 2 is fitted and attached to the recess 4G.
As described above, if the self-nail N is a relatively small diamond 2D, it can be attached by the nail or artificial nail decoration method according to this embodiment.
In any of the above-described examples, at least the pavilion portion 21 of the diamond 2 may be formed with a recess so as not to protrude to the surface side of the nail N or the artificial nail 1, 1A.

Next, another example of the artificial nail decorated using the nail or artificial nail decoration method according to the present embodiment will be described with reference to FIG.
In addition, about the structure and process similar to an above-described example, the same code | symbol is attached | subjected and description is abbreviate | omitted or demonstrated easily.
The artificial nail 1B of this example is configured by forming a resin layer 10 similar to the above on the upper surface of a nail tip (fake nail) T.
This nail chip T is formed of a synthetic resin material or the like in accordance with the nail shape, and is attached to the nail with a nail adhesive (glue) or the like so as to be detachably attached.
In the nail or artificial nail decoration method according to the present embodiment, the diamond layer 2 can be attached by forming the resin layer 10 on the nail tip T as described above, forming the recess 4.
Instead of forming the resin layer 10 on the nail chip T, the nail chip T may be grasped as an artificial nail, and a concave portion may be directly formed on the nail chip T to attach diamond. In such a case, the concave portion 4 may be formed in the nail tip T formed relatively thick, and the diamond 2 may be attached.

Next, another example of the rotary cutting tool used in the nail or artificial nail decoration method according to the present embodiment will be described with reference to FIGS.
12 (a) and 12 (b) show other examples of the rotary cutting tool used in the nail or artificial nail decoration method according to the present embodiment, (a) is a schematic front view, and (b). Is a schematic bottom view, and FIGS. 13 (a) and 13 (b) each show still another example of a rotary cutting tool used in the nail or artificial nail decoration method according to the present embodiment. Schematic front view, (b) is a schematic enlarged partially broken view taken along line YY in (a), and FIGS. 14 (a) and (b) are schematic diagrams showing other examples of the same rotary cutting tool. It is a front view.
In addition, about the structure similar to the above-mentioned rotary cutting tool 3, the same code | symbol is attached | subjected and description is abbreviate | omitted or simplified.

In the example shown in FIG. 12, the rotary cutting tool 3 </ b> A is different from the rotary cutting tool 3 in the configuration of the cutting part 31 </ b> A.
The cutting portion 31A has a plurality of positioning lines 34 (34a, 34b, 34c, 34d) formed on the outer periphery thereof.
These positioning lines 34 are formed at positions corresponding to the depths Pd1, Pd2, and Pd3 of the pavilion portions 21 of the diamonds 2C, 2A, and 2E having substantially the same shape and different sizes.
In the present embodiment, the positioning line 34 is formed at a position that takes into account the thickness Ta of the adhesive layer formed by the ultraviolet curable adhesive 5 applied to the recess 4 described above.

  The positioning lines 34 as described above are formed so as to be separated from each other so that the positioning lines 34 can be visually recognized. For example, the pavilion portion 21 of the diamond 2 having various sizes by a plurality of rotary cutting tools 3A. The positioning line 34 may be configured according to the depth Pd. That is, for example, one rotary cutting tool 3A has a positioning line in accordance with the depth Pd of the pavilion portion 21 of each diamond 2 having a size of 0.01 carat, 0.1 carat and 1.0 carat. 34, and the other rotary cutting tool 3A is positioned in accordance with the depth Pd of the pavilion portion 21 of each diamond 2 having a size of 0.005 carat, 0.05 carat and 0.5 carat. A plurality of rotary cutting tools 3A, such as forming the line 34, may be adapted to accommodate diamonds 2 having different sizes.

Thus, according to the rotary cutting tool 3A in which the positioning line 34 is formed at the position corresponding to the depth Pd1, Pd2, Pd3 of the pavilion portion 21 of each diamond 2C, 2A, 2E, each diamond 2 having a different size is provided. It becomes a tool which can easily form the recess 4 in accordance with the size of the. That is, since the concave portion 4 can be formed using the positioning line 34 as a guide, it is possible to reduce the depth of the concave portion 4 from being too deep or too large.
Further, by using the rotary cutting tool 3A in which the positioning line 34 is formed in this way, when the recess 4 is formed, the surface of the artificial nail 1 and the positioning line 34 are easily adjusted while being adjusted in parallel. Can cut. That is, it becomes a tool that can easily form the recess 4 vertically below the surface of the artificial nail 1.

In this example, the positioning line 34 is formed in the cutting portion 31A in consideration of the thickness Ta of the adhesive layer. However, the thickness of the adhesive layer is usually relatively thin. The positioning line 34 may be formed ignoring Ta.
Further, in this example, the positioning line 34 is exemplified by forming a circle having substantially the same shape as the outer peripheral diameter of the girdle portion 22 of each diamond 2 on the peripheral surface of the cutting portion 31A. However, the present invention is not limited thereto, and a point or the like is drawn at a position corresponding to the depth Pd of the pavilion portion 21 on the peripheral surface of the cutting portion 31A, and the positioning line 34 is formed by the rotation of the cutting portion 31A. Also good.

In the example shown in FIGS. 13 and 14, an example is shown in which a cutting member 31A of the rotary cutting tool 3A is further provided with a regulating member.
The regulating member 35 is for regulating the depth of the concave portion 4 when the concave portion 4 is formed, and is formed according to the depth Pd of the pavilion portion 21 of the diamond 2.
Specifically, as shown in FIG. 13 (b), the restricting member 35 is formed in a hollow, substantially cylindrical shape, and a flange portion is formed on the upper portion of the hollow inner surface 35c so as to protrude inward. 35d is provided around, and a tapered portion 35b having a tapered surface matching the shape of the cutting portion 31A is formed below the hollow inner surface 35c. When the restricting member 35 is attached to the rotary cutting tool 3A, the flange portion 35d and the tapered portion 35b are respectively provided on the peripheral surface of the cutting portion 31A and the peripheral surface of the truncated cone portion 33 of the rotary cutting tool 3A. It is abutted and regulated.

Further, the lower surface 35a of the restricting member 35 is attached to the rotary cutting tool 3A to match the depth Pd3 (see FIG. 12A) of the pavilion portion 21 of the diamond 2E from the tip portion of the cutting portion 31A. It is configured to have a height. In other words, from the lower surface 35a of the restricting member 35, a part of the cutting part 31A that is approximately the same size and size as the pavilion part 21 of the diamond 2E is exposed so as to protrude downward. .
The lower surface 35a serves as a restriction surface, and when the recess 4 is formed by the cutting portion 31A, the depth of the recess 4 is restricted.

Further, in the present example, the restriction member 35 is formed of an elastic member such as rubber, and can be detachably attached with elastic deformation by being fitted from the tip of the cutting portion 31A of the rotary cutting tool 3A. It is said that. Thus, by forming the restricting member 35 with an elastic member, the surface of the artificial nail 1 may be scratched even when it is cut until the lower surface 35a of the restricting member 35 contacts the surface of the artificial nail 1. You can prevent things.
14A, the regulating member 36 is configured such that the lower surface 36a has a height corresponding to the depth Pd2 (see FIG. 12A) of the pavilion portion 21 of the diamond 2A from the tip portion of the cutting portion 31A. Is attached to the rotary cutting tool 3A.
Moreover, in FIG.14 (b), the control member 37 comprised so that the lower surface 37a might become the height matched with the depth Pd1 (refer FIG.12 (a)) of the pavilion part 21 of the diamond 2C from the front-end | tip part of the cutting part 31A. Is attached to the rotary cutting tool 3A.

Thus, when forming the recessed part 4 as mentioned above by setting it as the rotary cutting tool 3A which provided the regulating members 35, 36, and 37 formed according to the depth Pd of the pavilion part 21 of the diamond 2, as described above. In addition, it is possible to effectively prevent the concave portion 4 from being formed too deep or too large, and the concave portion 4 that matches the shape of the pavilion portion 21 of the diamond 2 can be formed more reliably and easily. Moreover, since it can prevent forming the recessed part 4 too deeply, it becomes an excellent tool also in terms of safety. In other words, if cutting is performed until the lower surfaces 35a, 36a, 37a of the regulating members 35, 36, 37 are in contact with the surface of the artificial nail 1, the shape of the pavilion portions 21 of the diamonds 2E, 2A, 2C. It is possible to easily, reliably and safely form the concave portion 4 adapted to the above.
Further, as in this example, a plurality of restricting members 35, 36, and 37 are prepared according to diamonds 2 of different sizes, and are attached to the rotary cutting tool 3A so as to be detachable, so that one rotation. With the type cutting tool 3A, it is possible to easily form the recesses 4 of various sizes according to the diamonds 2 of different sizes. Further, even when the rotary cutting tool 3A cannot be used due to wear or the like, the regulating members 35, 36, and 37 can be used repeatedly.

The shapes of the regulating members 35, 36, and 37 are not limited to those shown in the drawings, and may be formed in accordance with the shape of the rotary cutting tool 3A.
Further, the regulating member may be formed of a soft synthetic resin material that can be elastically deformed instead of rubber or the like.
Further, the restriction member may be attached to the rotary cutting tool 3 in which the positioning line 34 is not formed.
Furthermore, in this example, the restricting member made detachable with respect to the rotary cutting tool 3A is illustrated, but it may be made non-detachable or formed integrally with the cutting part. . In such a case, each of the plurality of rotary cutting tools may be provided with a regulating member at a position corresponding to the depth Pd of the pavilion portion 21 of the diamond 2 having a different size.

  Further, the restriction member is not limited to the restriction member whose bottom surface is in contact with the surface of the artificial nail 1 and restricts the depth of the recess 4 as described above. A compression spring or the like configured to stop at a position corresponding to the depth Pd of the two pavilion portions 21 is attached to the chuck portion 81a of the rotary hand piece 80 or attached to the rotary cutting tool 3A. You may do it. In such a case, the artificial nail 1 may be cut by the cutting portion of the rotary cutting tool until the compression spring is compressed and stopped.
