Description

[0001] A METHOD FOR CREATING A FRENCH DESIGN ON A HUMAN'S NAIL

[0002] DESCRIPTION

[0003] The invention relates to methods for carrying out cosmetic procedures, namely to methods for creating a manicure or pedicure [A45D 29 / 00, A61 Q 3 / 02].

[0004] A FRENCH ARTIFICIAL NAIL is known from the prior art [USA2016249724A1], comprising an artificial nail base and a French portion, the body of the artificial nail includes a cuticle edge facing the root of the nail and a free edge continuing to the tip of the nail and curved downwards to both its lateral sides to form a curved surface, the French portion is formed on the upper surface of the free edge of the body of the artificial nail, the body of the artificial nail is attached to the fingernail or toenail of the user using glue and has a lower modulus of elasticity than the French portion

[0005] The closest in technical essence is the METHOD OF MANUFACTURING MULTI-COLORED ARTIFICIAL NAILS [US5927293A], where a mold is used, at the tip of which a partition is provided, which divides the surface of the nail into two parts, by applying acrylic materials of different colors to the two areas, filling the areas up to the dam, it is possible to create a nail that has more than one color and has a clearly defined border between the areas of different colors, in another embodiment, the cofferdam is attached directly to the nail, and part of the acrylic material is applied to a temporary form attached to the nail.

[0006] The main technical drawbacks of the analog and prototype include the insufficient quality of the French design transfer onto the human nail due to non-compliance with certain technological processes that directly impact the quality of the design transferred onto the human nail. The technical result of the invention is to improve the quality of the French design transfer onto the human nail using a nail form with a border.

[0007] The said technical result is achieved by a method for creating a French design over a person's nail, characterized by the fact that a plastic mold with a protruding edge in the inner part of the mold is selected according to the size of the user's nail, the modeling material is applied over the inner wall of the mold in the area above the "smile line", the modeling material is applied, stopping near the edge, then the modeling material is polymerized, after the first polymerization, the modeling material is applied under the mold in the area of ​​the nail bed, then the mold is installed on the person's nail, then the modeling material is polymerized again, after the second polymerization, the mold is removed from the nail and the modeling material is applied to the resulting depression in the area of ​​the nail bed, then polymerization is carried out once more, after the third polymerization, the finished design is covered with a protective composition and polymerized once more.

[0008] In particular, gel, polygel, acrylgel, acrylate, gel polish or gel paint are used as modeling materials.

[0009] Specifically, polymerization is carried out using a UV or LED emitter. Specifically, the modeling material is applied under the mold edge to a thickness of at least 0.1 mm.

[0010] Specifically, polymerization takes place in a range of 3 seconds to 15 minutes. Specifically, the mold edge is widened at the bottom.

[0011] Brief description of the drawings.

[0012] Fig. 1 shows a general view of a form with a border for transferring a French design over a person’s nail.

[0013] The figure shows: 1 - outer wall of the form, 2 - inner wall of the form, 3 - side, 4 - chamfer, 5 - marking, 6 - nail bed area of ​​the form.

[0014] Implementation of the invention.

[0015] In the description of the declared technical solution, “UV or LED emitter” refers to a device for polymerizing the modeling material (polymer), which is a UV lamp, LED lamp, or UV flashlight.

[0016] The method for creating a French design on a person's nail is characterized by the user first selecting a mold based on the size of their nail so that it fits comfortably over the entire surface of the nail. The mold is made of a polymer material, specifically plastic. The mold has an outer wall (1) and an inner wall (2). The thickness of the mold ranges from 0.5 to 1 millimeter. The length of the mold is 5 centimeters. The width of the mold ranges from 8 to 25 millimeters. On the lower part of the outer wall (1) is a transverse marking (5). On the upper part is a graphic identification element, which can be a graphic or digital designation that contributes to the distinctiveness of a particular mold over which this graphic element is applied. On the inner wall (2) is a border (3). Border (3) is a raised area ranging from 0.5 to 1 millimeter in height.On the back of the mold, there is a chamfer 4. This chamfer is designed and angled to prevent unwanted modeling material from appearing near the cuticle of the nail plate during final polymerization. In one embodiment, the inner rim 3 is widened at the bottom (not shown in the figure). First, a nail modeling material is applied to the inner wall 2 using a stick or spatula, stopping at the rim 3. Modeling material can include gel, polygel, acrylic gel, acrylate, gel polish, or gel paint. The modeling material is applied at a thickness of at least 0.1 mm. Ridge 3 inside the plastic mold acts as a flow limiter. This allows for the separation of several polymers (modeling materials), thereby creating a "smile line" graphic element for a French nail design.Next, the mold with the modeling material applied inside is cured using a UV or LED light. The first layer of modeling material is cured during the radiation exposure, which lasts from 3 seconds to 15 minutes.

[0017] After the initial polymerization, the mold is removed from the UV or LED lamp. Next, a modeling material is applied to the mold in the nail bed area. Gel, polygel, acrylic gel, acrylate, gel polish, or gel paint are all suitable materials. The applied layer of modeling material should be at least 0.1 mm thick. The mold is then fixed to the nail and polymerized under a UV or LED lamp for 3 seconds to 15 minutes.

[0018] After the second polymerization, the mold is removed from the nail, and a modeling material is applied to the resulting depression in the nail bed of the user or the nail template. Modeling materials include gel, polygel, acrylic gel, acrylate, gel polish, and gel paint. The applied layer of modeling material should be at least 0.1 mm thick. The nail is then polymerized again under a UV or LED lamp for 3 seconds to 15 minutes.

[0019] After the third polymerization, the adhesive layer is removed from the nail using a wipe soaked in a liquid to remove residual tack. Any excess material or other design defects are removed by filing with a nail file, buffing tool, or milling cutter. Next, the nail is coated with a protective coating and polymerized in a UV or LED lamp for 3 seconds to 15 minutes. In one embodiment of the claimed invention, the entire French design process is performed not on the nail itself, but on a plastic template. After the template is created, it is placed on the nail at the desired time, fixing the finished design onto a drop of modeling material. The modeling material used is gel, polygel, or base. After the material is fixed to the nail, it is polymerized in a UV or LED lamp for 3 seconds to 15 minutes.

[0020] The stated technical result—improving the quality of French design transfer onto a human nail when using a nail mold with a border—is achieved by using a mold with a raised border 3 in the inner part of mold 2 during the transfer. This is necessary to separate the polymers (modeling material) on the surface of the human nail / blank when creating the French design, creating a clear line between them, and preventing the mixing of multiple polymers during the creation of the design. Mixing multiple polymers will result in a low-quality French design.

[0021] The modeling material is applied over inner wall 2, stopping near edge 3, and then polymerized. This is necessary for creating the first half of the French design—the design of the nail plate and the area above the smile line. Polymerization is necessary to secure the polymer to the nail / nail and prevent it from leaking outside the mold or mixing with polymers of other colors. Mixing multiple polymers will result in a low-quality French design.

[0022] After the initial polymerization, the modeling material is applied under the mold to the nail bed area, then polymerized again. This is necessary to create the second part of the French design—the nail bed and the area under the smile line. Polymerization is necessary to secure the polymer to the nail / nail and prevent it from leaking outside the mold or mixing with polymers of other colors. Mixing multiple polymers will result in a low-quality French design.

[0023] After the second polymerization, the mold is removed from the nail and the modeling material is applied to the resulting depression in the nail bed area. The mold is then polymerized again. This is necessary to compensate for the difference in height between the first applied and polymerized modeling material and the second. This difference is due to the presence of a rim in the inner part of the mold. When transferred, the material above the "smile line" will be slightly higher than the material applied to the nail bed, creating a depression between the several materials. Furthermore, unevenness also appears near the cuticle after the modeling material has set in the nail bed area. Applying another layer of modeling material at this stage and then polymerizing it visually eliminates the depression between the materials and the cuticle, thereby creating a more aesthetically pleasing and high-quality design.

[0024] After the third polymerization, the finished design is coated with a protective compound and polymerized again. This is necessary to ensure the design is more durable, resists deformation from environmental influences, and produces a higher quality finish. Skipping this step reduces the overall quality of the transferred design.

[0025] The modeling material is applied to the mold edge at a thickness of at least 0.1 mm. Applying less than 0.1 mm results in a thinner layer of transferred polymer and higher brittleness, which negatively impacts the overall quality of the finished design.

[0026] Curing time ranges from 3 seconds to 15 minutes. Curing the modeling material for less than 3 seconds (depending on the power of the UV or LED emitter) risks under-curing the polymer, which will result in the design not adhering to the nail / nail and not hardening. Curing for more than 15 minutes (depending on the power of the UV or LED emitter) risks burning the polymer, thereby damaging the finished design and negatively impacting its quality.

[0027] In the embodiment, the claimed technical result can be achieved by thickening the lower part of the side 3, due to which the likelihood of material leaking from one part of the mold to another is reduced at all stages of the method implementation.

[0028] As confirmation of the achievement of the technical result, the results of a number of experiments are presented below:

[0029] 1) Creating a French design on a person’s nail without using a form with a border in its inner part (Hereinafter - A1).

[0030] 2) Creation of a French design without polymerization after each stage (Hereinafter - A2).

[0031] 3) Creation of a French design without filling the depression in the nail bed area formed after the second polymerization with modeling material (hereinafter - AZ).

[0032] 4) Creation of a French design without covering it with a protective layer (Hereinafter - A4).

[0033] 5) Creation of a French design with the application of modeling material under the edge of the form with a thickness of less than 0.1 mm (hereinafter - A5).

[0034] 6) Creation of a French design, where polymerization is done in less than 3 seconds or more than 15 minutes (Hereinafter - A6).

[0035] 7) Creation of a French design in compliance with all the features described in this invention application (Hereinafter - A7).

[0036] After all the tests were completed, the final product was worn for 5 minutes in a laboratory setting by a user and then compared to the reference design. Based on the comparison, the prototype was assigned a quality score (also known as a similarity score) for the final design (also known as a similarity score to the reference design). The results are recorded in Table 1. Based on the results of a series of experiments, the following conclusion can be drawn: taken together, all the stated features make it possible to achieve the stated technical result of the claimed method - improving the quality of transferring the French design onto a person's nail.
