FIG. 1 is a flowchart of a method for manufacturing artificial nails 100 according to the present embodiment.

2 to 4 are photographs schematically showing the manufacturing process of the artificial nail 100 of the present embodiment.

A method for manufacturing the artificial nail 100 according to the present embodiment will be described with reference to FIGS. 1 to 4.

The method of manufacturing the artificial nail 100 of the present embodiment is a method of manufacturing the artificial nail ₁₀₀ to be attached to the customer's nail N1.

First, the customer packs the first dental silicone impression material 10 in the protective device (S10 in FIG. 1, FIG. 2 (a), FIG. 2 (b) and FIG. 2 (c)).

The first dental silicone impression material 10 is a silicone impression material used, for example, when taking a tooth mold or recording the engagement of upper and lower teeth. The first dental silicone impression material 10 is, for example, a two-component (two-paste) addition-curing type dental silicone impression material. FIG. 2A illustrates the first paste 12 and the second paste 14 used in the production of the first dental silicone impression material 10. _In addition, FIG. 2A also shows the customer's hand H1.

For example, the first dental silicone impression material 10 is manufactured by kneading the first paste 12 and the second paste 14 as shown in FIG. 2B. The first dental silicone impression material 10 is not limited to the above.

The protective tool 20 is a thin dish-shaped base on which the _first dental silicone impression material 10 before curing is placed and pressed against the customer's nail N1 described later. The size of the protective device 20 is, for example, _about the same size as the customer's nail N1. Here, there are considerable individual differences in the size of the nails. The size of the nail is not always proportional to the size of the hand. Even people with large hands may have relatively small nails. Therefore, the size of the protective tool 20 is appropriately selected according to the size of the customer's nail _N1 . For example, a nail tip having a size of 10 or 12 which is common in the world can be used as a protective device 20. However, what can be applied as the protective device 20 is not limited to such nail tips.

Next, the customer presses the _first dental silicone impression material 10 packed in the protective tool 20 against the customer's nail N1 via the protective tool 20. Then, the claw mold 30 of the customer's claw N1 is manufactured (S14 in FIG. ₁ , FIG. 2 (d), FIG. 3 (a) and FIG. 3 (b)).

FIG. 2D is a diagram in which the customer presses the _first dental silicone impression material ₁₀ packed in the protective device 20 against the customer's nail N1 of the customer's finger (right thumb) F1. be. At this time, the customer is pressing the protective device ₂₀ using the customer's finger (left thumb) F2. The protective device 20 is packed with the first dental silicone impression material 10. Then, the first dental silicone impression material ₁₀ is pressed against the customer's nail N1 via the protective device 20. In other words, the customer is pressing the first dental silicone impression material against the customer's nail N ₁ with the customer's finger (left thumb) F ₂ in direct contact with the first dental silicone impression material 10. is not. The customer indirectly presses the _first dental silicone impression material 10 against the customer's nail N1 by using the protective device 20.

FIG. 3A is a diagram in which the first dental silicone impression material 10 is pressed against the customer's finger (right thumb) F1 to cure the _first dental silicone impression material 10. At this time, the customer preferably presses the first dental silicone impression material 10 so that the first dental silicone impression material 10 protrudes from the protective tool 20. Further, it is preferable that the customer's nail N ₁ is completely covered with the first dental silicone impression material 10. FIG. 3B shows a nail mold 30 manufactured by curing the first dental silicone impression material 10.

Next, the nail technician fills the nail mold 30 with the second dental silicone impression material 40 to manufacture the customer's finger model 50 having the nail portion 52 (S18 in FIG. 1, FIG. 3 (c)). And FIG. 3 (d)).

For example, the claw mold 30 manufactured by the customer is transported by means of transportation and delivered to the nail technician. Then, the nail technician manufactures the finger model 50 using the claw mold 30. The nail technician is an example of a second person.

The second dental silicone impression material 40 is a silicone impression material used, for example, when taking a tooth mold or recording the engagement of upper and lower teeth. The second dental silicone impression material 40 is, for example, a two-component (two-pasty) addition-curing type dental silicone impression material. FIG. 3 (c) illustrates the third paste 42 and the fourth paste 44 used in the production of the second dental silicone impression material 40. Note that _FIG . 3C also shows the manicurist's hand H2.

For example, the second dental silicone impression material 40 is manufactured by kneading the third paste 42 and the fourth paste 44 by a nail technician as shown in FIG. 3 (c). Then, the nail technician packs the second dental silicone impression material 40 in the nail mold 30 as shown in FIG. 3 (d). In this way, the nail technician manufactures the customer's finger model 50 with the claw portion 52. The claw portion 52 and the finger model 50 are shown in FIG. 4 (a).

The hardness of the second dental silicone impression material 40 is preferably higher than the hardness of the first dental silicone impression material 10.

The second dental silicone impression material 40 is not limited to the above.

Next, the nail technician applies the first gel 60 on the claw portion 52 of the finger model 50 (S24 in FIG. 1 and FIG. 4A). After this, the nail technician cures the first gel 60. The first gel 60 and the second gel 62, which will be described later, are gels that become the nail 100 after curing. The first gel 60 and the second gel 62 are, for example, UV (Ultraviolet) curable gels. The first gel 60 and the second gel 62 are applied by, for example, a brush B, but the method of application is not limited thereto.

The claw portion 52 of the finger model 50 shown in FIG. 4A is lengthened by providing a portion 54 having a long claw at the tip of the claw portion 52. The nail lengthened portion 54 is preferably manufactured by a nail technician, for example, by adding a second dental silicone impression material to the nail portion 52 prior to application of the first gel 60. However, the nail technician may lengthen the nail portion 52 by adding something other than the second dental silicone impression material to the nail portion 52.

Next, the nail technician applies the second gel 62, which has a higher self-leveling property than the first gel 60, on the first gel 60 (S26 in FIG. 1, FIG. 4 (b)). After this, the nail technician cures the second gel 62. Of course, acrylic (acrylic) may be used instead of the first gel 60 and the second gel 62.

Next, the nail technician peels off the artificial nail 100 obtained by curing the first gel 60 and the second gel 62 from the finger model 50 (S30 in FIG. 1). Then, the nail technician appropriately decorates the artificial nail 100. FIG. 5A is a photograph showing an example of the artificial nail 100 obtained by the method for manufacturing the artificial nail 100 according to the present embodiment. The artificial nail 100 is fixed to the customer's finger F using double-sided tape as shown in FIG. 5 (b). Here, in the case of the artificial nail 100 created by using the finger model 50 having no extended portion 54, the double-sided tape having a film thickness of 0.13 mm or more and less than 0.35 (an example of the first double-sided tape). ) Is preferred. Further, in the case of the artificial nail 100 created by using the finger model 50 having the portion 54 in which the nail is lengthened, a double-sided tape having a film thickness of 0.35 mm or more and 0.55 mm or less (an example of the second double-sided tape) is used. It is preferable to use and fix it.

Next, the action and effect of the artificial nail manufacturing method of the present embodiment will be described.

Compared to having your nails decorated at a nail salon, using artificial nails has the advantage that you can easily remove them on a daily basis. In particular, for customers who are in a hygiene-conscious profession, such as medical professionals, even if they directly decorate their nails, they will be dropped during work. However, in the case of artificial nails, you can enjoy the decoration of the nails more easily.

In addition, if an infectious disease including a new coronavirus infection is prevalent, there is a risk of being infected with the infectious disease when the customer goes to a nail salon. However, in the case of artificial nails, you can enjoy the decoration of the nails at home, so you can reduce the risk of getting an infectious disease.

On the other hand, there are at least three reasons why artificial nails are difficult to use. The first is that artificial nails usually have 12 sizes that are common in the world, but such 12 size artificial nails often do not fit your nails. Claw shapes include at least circular claws, beetle claws, biting claws, trapezoidal claws, sled claws and deep claws. The shape of the nail is different for each of the 10 fingers that a person has. Therefore, the shape of the nail is very diverse. It is extremely difficult to cover such a variety of nail shapes with the above-mentioned 12 size artificial nails. Specifically, for example, there was a problem that the artificial nails protruded from the customer's nails, the customer's nails protruded from the artificial nails, and the curvature of the artificial nails did not match the curvature of the customer's nails. ..

The second reason is that artificial nails made in 12 sizes, which are common throughout the world, have a small number of designs and often do not suit the tastes of customers.

The third reason is that artificial nails made in 12 sizes, which are common throughout the world, are often made of plastic and may not fit your nails sufficiently.

Therefore, in the method for manufacturing a nail nail of the present embodiment, the customer protects the first dental silicone impression material packed in the protective tool and the customer protects the first dental silicone impression material packed in the protective tool. The process of manufacturing the nail mold of the customer's nail by pressing it against the customer's nail through the tool, and the nail technician has a second dental silicone impression material that is harder than the first dental silicone impression material in the nail mold. The process of manufacturing the customer's finger model with the nail part by packing, the process of the nail technician applying the first gel on the nail part, and the process of the nail technician applying the first gel on the first gel. It comprises a step of applying a second gel having a higher self-leveling property, and a step of a nail technician peeling off the nails obtained by curing the first gel and the second gel from the finger model.

According to the above manufacturing method, the customer manufactures the nail mold of the customer's nail. Then, the nail technician manufactures artificial nails using such a nail mold. Since the nail mold is so small, the customer can easily send the nail mold to the nail technician. Therefore, the risk of the customer getting an infectious disease is reduced. On the other hand, the nail technician can make full use of the nail technician's technique to decorate the artificial nails according to the customer's taste.

More specifically, the customer packs the first dental silicone impression material 10 in the protective device 20. Then, the customer presses the first dental silicone impression material 10 packed in the protective tool 20 against the customer's nail N ₁ via the protective tool 20 to manufacture the nail mold 30 of the customer's nail N ₁ . ..

Dental silicone impression materials are excellent in producing nail molds that accurately reproduce the shape of the nail. In particular, the nail has fine concave portions and convex portions, but it is particularly excellent in that the fine concave portions can be accurately reproduced. Unlike the convex portion, the impression material is required to invade the fine concave portion, but the dental silicone impression material easily invades the concave portion.

_The size of the protective device 20 is appropriately selected according to the size of the customer's nail N1.

As an example, it is preferable that the customer presses the first dental silicone impression material 10 against the customer's nail N ₁ so that the first dental silicone impression material 10 protrudes from the protective device 20. The reason is a simple criterion such as "If the first dental silicone impression material 10 protrudes from the protective device 20, the nail N ₁ is sufficiently covered with the first dental silicone impression material 10." Because it can be applied.

In particular, in the method for manufacturing artificial nails according to the present embodiment, the nail technician who is accustomed to the work does not create the nail mold 30, but the customer who is not accustomed to the work creates the nail mold 30. Therefore, it is important to use a protective device 20 of an appropriate size.

When the first dental silicone impression material 10 is pressed through the protective tool 20, the customer's hand does not directly touch the first dental silicone impression material 10, so that the pressing force may be too strong or too weak. Less.

Then, the nail technician fills the nail mold 30 with the second dental silicone impression material 40. As a result, the finger model 50 having the claw portion 52 is manufactured. Here, the reason why the hardness of the second dental silicone impression material 40 is higher than the hardness of the first dental silicone impression material 10 is that when the finger model 50 is scraped in a subsequent step, the higher the hardness, the more the shape of the finger model 50. This is because it does not easily collapse and the finger model 50 can be easily processed. Since the nail technician is in charge of the manufacturing process from here, it is possible to manufacture the artificial nail 100 with higher quality.

Next, the nail technician applies the first gel 60 on the nail portion 52. Next, the nail technician applies the second gel 62, which has a higher self-leveling property than the first gel 60, on the first gel 60. As the first gel 60, for example, a gel having low fluidity and having little surface tension is used. Therefore, even if the first gel 60 is applied to the end of the nail portion 52, the gel does not shrink, and the artificial nail ₁₀₀ having a size that fits well to the end of the customer's nail N1 can be manufactured. On the other hand, for example, when the first gel 60 is applied using the brush B, the trace of the brush remains as it is. Therefore, it is preferable to apply the first gel 60 so as to have a three-layer structure of "abdominal nail", "intermediate nail on the intermediate nail" and "back nail on the intermediate nail" similar to human nails. .. Here, the "abdominal nail" is formed by applying the first gel 60 to the nail portion 52 in the vertical direction. The "intermediate nail" is formed by applying the first gel 60 laterally to the nail portion 52. The "back claw" is formed by applying the first gel 60 to the claw portion 52 in the vertical direction. After applying the first gel 60 as described above, the surface of the artificial nail is smoothed by using the second gel having higher self-leveling property. Unlike acrylic artificial nails, for example, artificial nails manufactured using gel in this way are deformed according to the movement and bending of human fingers, so there is little discomfort when wearing them, and you can spend your time comfortably. Therefore, it is possible to manufacture artificial nails that fit well to human nails. Generally, a soft gel is first applied to the claw portion 52 of the finger model 50, and then a hard gel is applied onto the soft gel. The reason for applying the soft gel first is that it adheres to the nails, is difficult to lift from the nails, and is difficult to peel off. However, when the soft gel applied to the end portion of the nail portion 52 is applied, the soft gel shrinks and the end portion of the manufactured artificial nail does not fit sufficiently.

When the customer fixes the artificial nail 100, it is preferable to use a first double-sided tape having a film thickness of 0.13 mm or more and 0.35 mm or less. Further, when the customer fixes the artificial nail 100, it is also preferable to fix the artificial nail 100 using a second double-sided tape having a film thickness of more than 0.35 mm and 0.55 mm or less. When the first double-sided tape having a film thickness of 0.13 mm or more and 0.35 mm or less is used, since the film thickness is relatively thin, it is possible to obtain a feeling that the artificial nail 100 fits the nail better. Further, when fixing with a second double-sided tape having a thickness of more than 0.35 mm and 0.55 mm or less, the artificial nail 100 can be fixed more firmly, for example, when the artificial nail 100 is washed with water. Even so, the artificial nail 100 is less likely to fall. If the film thickness of the double-sided tape is thinner than 0.13 mm, it becomes difficult to fix the artificial nail 100 with sufficient adhesive force, so that the artificial nail 100 is easily dropped from the hand. On the other hand, when the film thickness of the double-sided tape is thicker than 0.55 mm, it becomes difficult to obtain a feeling that the artificial nail 100 sufficiently fits the nail.

According to the method for manufacturing artificial nails according to the present embodiment, it is possible to provide a method for manufacturing artificial nails that can remotely manufacture artificial nails that fit well with human nails.

(Example)
Hereinafter, the examples will be described in more detail in comparison with the comparative examples.

(Example 1)
first. The customer mixed a commercially available 2-paste dental silicone impression material as the first dental silicone impression material 10 in 30 seconds, and then packed it in the protective tool 20. The protective device 20 is, for example, a plastic nail tip, but is not limited thereto.

Next, the customer presses the above _- mentioned dental silicone impression material packed in the protective tool 20 against the customer's nail N1 so that the dental silicone impression material protrudes from the protective tool 20 via the protective tool 20. The customer's nail mold 30 was manufactured.

Next, the nail technician packs another commercially available two-paste dental silicone impression material as the second dental silicone impression material in the nail mold 30, and the customer's finger model having the nail portion 52. 50 was manufactured.

Next, the nail technician applied the first gel 60 on the nail portion 52. Next, the nail technician cured the first gel 60 with, for example, UV light, and then applied the second gel 62 on the first gel 60. The nail technician then cured the second gel 62, for example with UV light.

Next, the nail technician peeled off the artificial nails obtained by curing the first gel 60 and the second gel 62 from the finger model 50.

Next, the customer fixed the artificial nail to the customer's nail N1 using a double _- sided tape having a film thickness of 0.13 mm. Such artificial nails fit the customer's nail _N1 very well. In addition, even after the customer washed his hands with water 50 times, the artificial nails did not fall off.

(Example 2)
The customer fixed the artificial nail created in the same manner as in Example ₁ to the customer's nail N1 using a double-sided tape having a film thickness of 0.28 mm. Such artificial nails fit the customer's nail _N1 very well. In addition, even after the customer washed his hands with water 50 times, the artificial nails did not fall off.

(Example 3)
The customer fixed the artificial nail created in the same manner as in Example ₁ to the customer's nail N1 using a double-sided tape having a film thickness of 0.34 mm. Such artificial nails fit the customer's nail _N1 very well. In addition, even after the customer washed his hands with water 50 times, the artificial nails did not fall off.

(Example 4)
The customer fixed the artificial nail created in the same manner as in Example ₁ to the customer's nail N1 using a double-sided tape having a film thickness of 0.35 mm. Such artificial nails fit the customer's nail _N1 well. In addition, even after the customer washed his hands 100 times with water, the artificial nails did not fall off.

(Example 5)
The artificial nail created in the same manner as in Example ₁ was fixed to the customer's nail N1 by the customer using a double-sided tape having a film thickness of 0.46 mm. Such artificial nails fit the customer's nail _N1 well. In addition, even after the customer washed his hands 100 times with water, the artificial nails did not fall off.

(Example 6)
The customer fixed the artificial nail created in the same manner as in Example ₁ to the customer's nail N1 using a double-sided tape having a film thickness of 0.50 mm. Such artificial nails fit the customer's nail _N1 well. In addition, even after the customer washed his hands 100 times with water, the artificial nails did not fall off.

(Example 7)
The customer fixed the artificial nail created in the same manner as in Example ₁ to the customer's nail N1 using a double-sided tape having a film thickness of 0.55 mm. Such artificial nails fit the customer's nail _N1 well. In addition, even after the customer washed his hands 100 times with water, the artificial nails did not fall off.

(Example 8)
The nail technician added another commercially available 2-paste dental silicone impression material as the second dental silicone impression material 40 used in Example 1 to the tip of the nail portion 52 to lengthen the nail. Part 54 was manufactured. After that, the nail technician applied the first gel 60. Other than that, artificial nails were manufactured in the same manner as in Example 1. The customer fixed the artificial nail to the customer's nail N1 using double _- sided tape having a film thickness of 0.28 mm. Such artificial nails fit the customer's nail _N1 very well. In addition, even after the customer washed his hands with water 50 times, the artificial nails did not fall off.

(Comparative Example 1)
FIG. 6 shows a finger model 50 created using the second dental silicone impression material 40 and a finger model 500 created using a commercially available silicone impression material for technicians. The finger model ₅₀ beautifully reproduces the shape of the customer's nail N1 with the shape of the tip of the nail. However, the finger model 500 does not reproduce the shape of the customer's nail _N1 because the tip of the nail is chipped.

As described above, it was found that the shape of the customer's nail _N1 can be reproduced beautifully by using the dental silicone impression material.

(Comparative Example 2)
As shown in FIG. 7 (a), the dental silicone impression material is not packed in the protective device but is formed into a flat shape, and the customer's finger is pressed one by one, as shown in FIG. 7 (b). , Five nail molds were manufactured with one dental silicone impression material.

However, in this case, it was found that the dental silicone impression material started to harden while the five fingers were alternately pressed, so that the nail mold could not be manufactured neatly. It was also found that if one tries to press the fingers one after another in a hurry, the next finger is pressed before the nail mold becomes sufficiently hard, so that the nail mold cannot be manufactured neatly. It was also found that when one finger was pressed against the mold, the molds of the other fingers that had already been manufactured were distorted, and the nail mold could not be manufactured neatly.

On the other hand, in the method for manufacturing artificial nails of the present embodiment, since a relatively small amount of the first dental silicone impression material is pressed against the finger one by one, the above-mentioned problem does not occur. ..

(Comparative Example 3)
As shown in FIG. 8, the nail mold 301 was manufactured by grasping one dental silicone impression material with five fingers. Then, the finger model 501 was manufactured using the claw mold 301.

However, it was found that in this case, the fingertips inevitably shake during the manufacturing of the nail mold 301, and the nail mold 301 cannot be made well. The reason is that each finger has a first joint, a second joint, and a third joint, and is in a very easy-to-move state, and it is difficult to make the finger rest.

On the other hand, in the method for manufacturing artificial nails according to the present embodiment, the protective device is filled with the first dental silicone impression material 10 and pressed against the fingers one by one. Therefore, even if the knuckles move during the manufacture of the nail mold, the protective device and the first dental silicone impression material easily follow the movement. Therefore, the nail mold can be manufactured neatly.

(Comparative Example 4)
A nail mold was created using a protective device 302 as shown in FIG. 16 that completely covers the portion of the first joint of the finger.

However, since a large amount of silicone impression material is put on the finger, it is difficult to quickly manufacture all fingernail molds. Therefore, it was found that it is difficult to stably manufacture a nail mold.

On the other hand, in the method for manufacturing artificial nails according to the present embodiment, the protective device 20 is filled with the first dental silicone impression material 10 and pressed against the finger. In this case, since the amount of silicone impression material used is small and the nail mold can be easily removed from the nail, all fingernail molds can be manufactured relatively quickly.

(Second Embodiment)
In the method for manufacturing artificial nails according to the present embodiment, a second person fills a nail mold with a second dental silicone impression material having a hardness higher than that of the first dental silicone impression material. Acrylic powder and monomer liquid are applied on the nail part between the process of manufacturing a finger model having a nail part and the step of applying the first gel on the nail part by a second person. It is different from the method for manufacturing artificial nails in the first embodiment in that it further includes a step. Here, the description overlapping with the first embodiment is omitted.

FIG. 10 is a flowchart of the method for manufacturing artificial nails according to the present embodiment. Acrylic powder and monomer liquid are mixed and applied on the nail portion 52 (S23).

Also in the method for manufacturing artificial nails of the present embodiment, it is possible to provide a method for manufacturing artificial nails that can remotely manufacture artificial nails that fit well with human nails.

(Third Embodiment)
In the method for manufacturing artificial nails according to the present embodiment, the second person fills the nail mold with the second dental silicone impression material having a hardness higher than that of the first dental silicone impression material. In that the second person scrapes the finger model after the process of manufacturing the finger model with the nail part, and before the step of applying the first gel on the nail part by the second person. It is different from the manufacturing method of artificial nails of the first and second embodiments. Here, the description overlapping with the first and second embodiments is omitted.

FIG. 11 is a flowchart of the method for manufacturing artificial nails according to the present embodiment. The manicurist is scraping the finger model 50 (S22). In the flowchart of FIG. 11, the "step of the nail technician increasing the length of the nail portion (S20)" and the "step of the nail technician applying the acrylic powder / monomer liquid on the nail portion (S23)" are combined. Is illustrated. However, (S20) and (S23) are steps that may not be necessary.

FIG. 12 is an example of a finger model 50 suitable for applying the artificial nail manufacturing method of the present embodiment. In the case of the nail portion 52 having the recess 53, after a predetermined period of time has passed after the nail mold 30 is taken, the recess 53 moves toward the tip of the nail and does not fit sufficiently. Therefore, in such a case, it is preferable that the nail technician scrapes the concave portion 53 before applying the first gel 60.

Also in the method for manufacturing artificial nails of the present embodiment, it is possible to provide a method for manufacturing artificial nails that can remotely manufacture artificial nails that fit well with human nails.

In addition, the nail technician usually performs the treatment while holding the customer's finger F with the thumb and index finger of the nail technician. Here, in order to apply the _first gel 60 and the second gel 62 cleanly to the end of the customer's nail N1, the meat called the nail wall (sidewall) _next to the customer's nail N1 is spread or lowered. It is preferable to prevent the nail wall from getting colored or gel. Further, if the artificial nail ₁₀₀ is not made to match the size up to the end of the customer's nail N1, the own nail (customer's nail N1) will come out from the armpit of the artificial nail ₁₀₀ when the artificial nail 100 is attached. Here, when the artificial nail 100 is made by using the finger model 50, the nail wall cannot be expanded or lowered unlike the case where the customer's finger F is in front of the eyes. Therefore, the nail technician may scrape the concave portion 53 of the finger model 50 or peel the artificial nail 100 from the finger model and then scrape the artificial nail 100 later. In particular, if the outer peripheral portion of the artificial nail 100 is thick, it is ugly and unnatural. This is because it is natural for nails to grow from the inside of the finger and partly buried in the nail wall. Therefore, the outer peripheral portion of the artificial nail 100 may be scraped. The portion of the artificial nail 100 to be scraped is not limited to the outer peripheral portion of the artificial nail 100.
