Abstract
Description
Technical Field
[0001] The subject of the invention is a nail art styling kit comprising a self-adhesive sticker with overprinting. The invention also relates to a tree-shaped nail sticker for decorating and shaping nails. Background Art
[0002] There are many known ways to decorate the nails, the most common being the application of nail polish. Nail extension tips are also a very common modeling technique. These are rigid plastic coverings that mimic the nail. The tips are very precisely and permanently glued to the free edge of the nail. They match the natural nail according to color and may be coated with a transparent material. Before modeling, the length and shape of the tips are determined to optimize the application of hardening materials such as acrylic fibers. The tips correct irregularities in the structure and shape of the natural nail. Tips are also used to extend the nail. However, the tips can easily break off from the nail plate or break in the event of a head-on impact due to their rigidity. In addition, the application of the tips requires a skill set and specialized equipment. In addition, the tips themselves and their removal can have a negative impact on the condition of the nail plate.
[0003] The use of flat stickers to decorate the nail plate is a common method. There are resin stickers with solvents, water stickers, so-called decals, stickers that are applied using heat or vinyl stickers. Flat stickers adhere to the surface and after removal they are attached to the nail plate. In contrast to the tips, the formation of flat stickers does not fit the anatomical shape of the nail. Therefore, after being glued to the nail, they tend to fall off at the edges, which means short durability and unsightly appearance. In addition, flat resin-based stickers with solvents are stretched on the nail plate so that their surface matches the convex surface of the nail. It is true that resin-based stickers are very flexible, but their application requires some skills. In addition, in the case of resin-based stickers with solvents, they must be used within one day after opening, because the solvent evaporates from the sticker, so the unused stickers become dry and brittle and useless. Due to their brittleness, the edges of resin-based stickers fall off easily. In addition, stickers have an unpleasant odor, and frequent use leads to deterioration of the nail plate. However, water stickers are rather thin and delicate, which hinders their application on the nail. Similar to the above-mentioned stickers, water stickers are flat and must be adapted to the surface of the nail plate. Stickers applied using heat are another type of flat stickers. They are characterized by rigidity, which actually enhances the strength of the sticker, but at the same time require heating using a hair dryer or a special lamp in order to become more flexible and easy to shape on the nail plate. These stickers are difficult to apply and fix on the edges. In addition, they require the use of a heat source, such as a special lamp or a hair dryer. In addition, they tend to wrinkle, thus returning to a flat shape and falling off the nail, resulting in poor durability. A similar situation is the case of vinyl stickers designed to be applied without heating. They are characterized by better flexibility than heated stickers, but they are more delicate and have less durability. They also tend to return to their flat initial shape, deform on the nail, wrinkle, and, as a result, fall off the nail. In addition, their application requires some skills.
[0004] U.S. patent application US5415903A discloses a self-adhesive coating laminate for fingers and nails. The laminate consists of a film-forming polymer, which contains at least one plasticizer, a self-adhesive coating placed thereon, and a carrier foil covering a pressure-sensitive adhesive layer and removable again. The film-forming layer is also covered from the other side, at least on a portion of its surface, with a protective layer, which can also be removed and resists other components of the laminate and the materials used for its preparation. The invention is also applicable to a method for producing such a laminate and its application on toenails. The laminate according to the above patent application is a flat product that is easy to debond.
[0005] US patent application US 20130032163A1 discloses a system and method for applying foil to nails. The method of applying foil includes cleaning the nail surface, applying a first layer of nail polish, sticking the nail foil, and then applying a second layer of nail polish on the nail foil to seal the nail foil. The patent application describes flat application.
[0006] Furthermore, Polish patent application PL168252 discloses a method for manicure and a tool for manicure. The method for manicure consists in preparing thermoplastic, colored, adhesive plastic foil strips of the size of the nail, removing the paper that prevents the foil from adhering, heating such foil strips with hot air until they acquire a suitable plasticity, and then pressing them onto the nail, forming them according to the shape of the nail while adhering the heated foil to the nail. Then, the hot air flow is cut off and, after cooling the foil, its edges are cut to the size of the nail. For this purpose, a special device for manicure is used. This solution can provide lasting results, but it is time-consuming and laborious and requires a lot of skills. Moreover, since the foil strips need to be cut from larger sheets, only monochrome foils can be used without the opportunity to obtain repeatable decorative patterns.
[0007] In addition, US patent application US6328949B1 discloses a nail covering system, which includes scanning a person's nails to prepare a digitized image of the top surface of the nails, and shaping the covering material so that the nail covering material matches the top of the nails to create a sized nail cover. The above process can be performed in a beauty salon, but cannot be performed at home. The above process only obtains a two-dimensional plane projection of the upper surface of the nail plate.
[0008] Nail stickers have many of the above-mentioned disadvantages. Summary of the invention
[0009] The three-dimensional nail sticker according to the present invention eliminates these disadvantages and provides a new high-quality product. The purpose of the present invention is to develop a three-dimensional nail sticker that does not deform and returns to a flat shape, does not fall off after being adhered to the nail plate, and does not require heating or specialized tools and skill sets.
[0010] The object of the invention is a kit for decorating and shaping nails, comprising a foil with a thickness of 30 to 140 μm, preferably a thermoplastic, placed on a base layer. The foil has a self-adhesive coating from one side of the base layer. The foil with the self-adhesive coating and the base layer have at least eight different protrusions, which together with the base layer on the substrate form a permanently formed elastic three-dimensional nail sticker, however the protrusions reflect the shape of the anatomical nail. The permanent protrusions formed in the foil with the self-adhesive coating form a nail sticker that imitates the anatomical, three-dimensional form of the nail plate. The shape of the nail plate varies from person to person and can be distinguished by the width and roundness of the plate, so in order to meet the needs of as many users as possible, a one-hand or one-foot kit has at least 8 protrusions. The foil layer together with the self-adhesive coating is cut around the perimeter of each protrusion and allows the individual nail stickers to be separated from the base layer together with the self-adhesive coating. The base layer can be made of the same material as the foil. In the case of a thermoplastic foil and a thermoplastic base layer, the protrusions are formed by heating. The shaping can also be carried out using a mechanical method, applying mechanical pressure during hot or cold pressing.
[0011] Preferably, the base layer is made of amorphous polyethylene terephthalate APET or high impact polystyrene HIPS or polyethylene terephthalate PET or polyethylene terephthalate Glycol PETG or poly (methyl methacrylate) PMMA or acrylonitrile butadiene styrene ABS with a thickness of 200 μm in the case of thermoforming or resin or natural rubber or rubber or silicone coated with silicone or pulp form.
[0012] Preferably, the foil is made of polyvinyl chloride or linear low density polyethylene (LDPE) or polyethylene terephthalate (PET) or amorphous polyethylene terephthalate (APET) or polylactic acid (PLA).
[0013] Preferably, the base layer is coated with an additional outer coating from the self-adhesive side.
[0014] Preferably, the further outer coating is made of UV-hardening silicone.
[0015] Preferably, the self-adhesive coating is meant to have a skin-contactable adhesive.
[0016] Preferably, the self-adhesive coating is represented by an acrylic copolymer.
[0017] Preferably, the self-adhesive coating comprises an additive of a substance which cares for the nail plate.
[0018] Preferably, the self-adhesive coating comprises ceramides and / or vitamins and / or proteins as additives of substances caring for the nail plate.
[0019] Preferably, the self-adhesive coating comprises a pharmaceutically active substance, preferably a pharmaceutically active substance selected from antifungal substances and / or antibacterial substances.
[0020] Preferably, the two nail art kits are placed on the same base layer.
[0021] Preferably the foil has a decorative or solid colour overprint made directly on either surface.
[0022] Preferably, the overprint is covered with a protective layer.
[0023] Preferably, the protective layer is polyvinyl chloride stainless steel with a thickness of 30 microns.
[0024] Preferably, the foil layer and the self-adhesive coating are cut around the perimeter of each protrusion together with the base layer, in addition to the flat narrow strip connecting the protrusions together.
[0025] Preferably, the foil layer and the self-adhesive coating together with the base layer are cut around the entire perimeter of each protrusion.
[0026] Preferably, the foil layer and the self-adhesive coating are present as a single protrusion which is selected for application to one specific nail plate.
[0027] Preferably, the film layer and the self-adhesive coating comprise personalized protrusions made according to an individual order for a specific user.
[0028] Preferably, the film layer and the self-adhesive coating comprise 10 personalized protrusions made to a personal order for a specific user.
[0029] The antifungal and / or antibacterial substances used for treating the nail plate contained in the adhesive coating can be chosen from the known ones: ciclopirox, amorolfine, clindamycin, piroctone olamine, itraconazole, triclosan, tea tree oil, bifenazolin, urea.
[0030] The advantage of using active ingredients in the adhesive coating is that it ensures that the active ingredients of the drug can be supplied from the sticker to the entire surface of the nail plate, thanks to the three-dimensional matching with the protruding nail plate, and also to the sides of the nail plate, which is not possible with previously known flat stickers containing active healing ingredients. The use of stickers and active ingredients ensures a healing and cosmetic effect, because the infected nail layer is covered with foil. In addition, the use of stickers and nail polish, for example, protects the nail plate from harmful ingredients in nail polish, thereby accelerating the healing effect.
[0031] The invention also relates to a tree-like three-dimensional nail sticker for decorating and shaping nails, comprising a sticker with a self-adhesive coating placed on a base layer, wherein the tree-like three-dimensional nail sticker comprises a foil with a thickness between 30-140 μm placed on the base layer. The foil has a self-adhesive coating from one side of the base layer, and the foil together with the self-adhesive coating has protrusions, which, together with the base layer, permanently form a flexible three-dimensional nail sticker on the base, wherein the protrusions reflect the shape of the anatomical nail. In addition, the foil layer and the self-adhesive coating are cut around the periphery of the protrusions, wherein the base layer can be made of the same material as the foil, and in the following case, a thermoplastic foil and a thermoplastic base layer are used, and the protrusions are made by thermoforming.
[0032] Preferably, the tree-shaped nail sticker is part of a kit according to the invention.
[0033] The technical solution according to the present invention can be used for fingernails and toenails.
[0034] A kit for decorating and shaping nails is provided, which comprises a series of flexible stickers formed into anatomical shapes, eliminating the disadvantages of flat stickers and pointed tips. The tree-shaped nail stickers according to the invention have the same advantages. Manicure with the stickers according to the invention is simple, does not require any additional devices and can be directly performed by the individual, and the result is durable. The foil can be ready for use thanks to the overprint on one of its surfaces made directly on this surface, but it can also be transparent without overprint to allow the user to decorate it with, for example, multi-color lacquer and create his own, any combination of decorations. The foil performs a care function simultaneously with a care additive and with or without overprint. The spatially shaped stickers with "shape memory" do not deform and maintain their three-dimensional shape, anatomically fitting the nail shape. The three-dimensional shaping result of the stickers is maintained by the shaped base layer. They do not require stretching when used on the nails, the self-adhesive coating has an adhesive that is in safe contact with the skin and therefore does not damage the nails. In addition, in the case of the use of a care additive in the self-adhesive coating, it can care for and nourish the nail plate.
[0035] To use the solution according to the invention, the kit or sticker is removed from the packaging and the nail is cleaned by degreasing the nail plate. Then, among the available protrusions, the one that best matches the anatomical shape of the user's nail plate is selected. Next, the sticker is removed from the base layer. The unstuck sticker has a 3D shape that reflects the anatomical shape of the nail. Therefore, it can be easily applied to the nail. Next, the sticker is applied to the nail plate, starting from the nail lunula. Mechanical stretching of the sticker foil is not required, because the sticker formed according to the anatomical nail shape adapts to the nail plate. Therefore, the sticker is directly applied to the nail. At the final stage, the excess sticker is filed onto the nail with a file to match its size to the length of the nail. The sticker can also be additionally decorated with nail polish or other decorative means and its service life can be extended by applying additional preparations designed for this purpose.
[0036] The solution according to the invention provides a product characterized in that its shape represents the anatomical shape of the nail. The shape is determined by the protrusions formed on the base. According to the invention, a flexible three-dimensional sticker is provided, characterized in that the three-dimensional form of the protrusions is a part of a sphere. Such a shape leads to a significantly better adhesion of the sticker to the nail plate and a faster and easier application than solutions according to the prior art throughout the period of use of the product, since the product does not require stretching of a flat form onto a protruding nail. The sticker according to the invention is more durable than stickers known in the art (see Fig.10 A- Fig.10 Appearance and effect of the sticker C and the sticker of the present invention on the nail plate after one week of use ( Fig.11 D) Comparison of adhesion).
[0037] Another feature produced by the anatomical and 3D sticker forms is their ease of application on the nail plate. Pasting the sticker according to the invention does not require experience or any special technical preparation.
[0038] Importantly, their application is a more permanent operation than in the case of stickers according to the art. The self-adhesive coating is represented by a special adhesive, proven to come into contact with the skin, thus ensuring protection of the nail plate from harmful external factors.
[0039] An important feature of the solution according to the invention is the possibility of correcting irregularities in the structure and shape of the natural nail. The solution is intended to decorate and design the nail plate.
[0040] The sticker according to the invention can be provided in the form of a single protrusion. It allows the user to select a specific single shape from a variety of sizes and shapes (including atypical shapes). The sticker is selected by fitting the shape from a shape sampler in traditional sales channels (e.g. beauty salons, drugstores). The sticker can also be selected virtually using an application that scans the image of the user's hand and determines the three-dimensional shape of the nail plate based on the programmed feature points.
[0041] The sticker according to the present invention can be customized according to the shape of the nail plate of a specific user. It can cover the sticker onto the nail plate more accurately while increasing the ease of application and durability of the sticker. In traditional sales channels, such as beauty salons and pharmacies, the mapping of personalized protrusions is completed by scanning the surface of the user's nail plate using a 3D scanner. It is also possible to use a mobile or computer application to scan an image of the user's hand and determine the three-dimensional shape of the nail plate based on programmed feature points, thereby virtually drawing personalized protrusions.
[0042] The stickers according to the invention ordered individually according to the shape of the nails of the user's hands or feet contain a set of 10 protrusions. A digitized stereoscopic image of the shape of the nail plate is stored in the user database. Upon request, a set of personalized stickers for hands or toes is produced taking into account the characteristic shape of the user's nail plate while covering it with a decorative overprint selected from the catalog or personalized.
[0043] This solution has been tested to determine the best shape for the three-dimensional protrusions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0063] The following examples illustrate the present invention but do not limit the present invention in any way.
[0064] Example
[0065] Example 1:
[0066] To make a kit for nail decoration and shaping, a three-dimensional base with different protrusions that reflect the anatomical shape of the nail plate is first developed. The base can be made of any material that can be permanently shaped to represent the basis of the protrusions in the correct condition (anatomical shape of the sticker). The base can be made of epoxy resin, aluminum, medium-density fiberboard (MDF), rubber, silicone and shaped using casting technology, 3D printing, injection molding or numerical control (CNC) machines. Then, a multi-colored geometric pattern for decorating the nail plate is printed on a flat, unshaped polyvinyl chloride foil with a thickness of 60 μm. The pattern can be any ornament, uniform color or other decorative form. The print is additionally coated with polyvinyl chloride with a thickness of 30 μm to protect the print. The flat, unshaped and printed polyvinyl chloride thermoplastic foil is coated with an acrylic copolymer, which is a self-adhesive coating in the next stage. The adhesive is skin-contact-proof, so it is harmless and almost odorless. The adhesive has added ceramides as substances for the care of the nail plate. The foil is applied together with the self-adhesive coating on a base layer made of amorphous polyethylene terephthalate APET with a thickness of 200 μm, which is coated with UV-hardening silicone from the self-adhesive side and applied to the base. The whole is heated to achieve a significant softening of the materials used. The protrusions of the thermoplastic foil are made using a base that reflects the anatomical shape of the nail plate. The base protrusions are permanently replicated on the foil together with the self-adhesive coating and the base layer. In the next stage, the foil is cut together with the self-adhesive coating around the perimeter of each protrusion, thus forming a self-adhesive nail sticker. The sticker remains glued to the base layer. The sticker can be cut using a punch, laser or plotter. Preferably, the anatomically shaped nail sticker kit includes at least 8 protrusions, allowing the user to choose the appropriate shape and size and accurately match the personal shape of a given nail plate of a single hand. Two analog kits form a set suitable for both hands or both feet.
[0067] The kit provided for decorating and shaping nails comprises a polyvinyl chloride foil 1 with a thickness of 60 μm having a decorative overprint 2, additionally covered with a polyvinyl chloride protective layer 3 with a thickness of 30 μm. On the other side, the foil 1 is covered with a self-adhesive coating 4 of a copolymer of acrylic acid and ceramide. The foil 1 is located on a base layer 5 of amorphous polyethylene terephthalate with a thickness of 200 μm, which is coated from one side with an additional UV-hardening silicone outer coating 6. The foil 1 together with the self-adhesive coating 4 and the bottom base layer 5 have eight different protrusions 7, which together with the base layer 5 form a nail sticker 8. The foil 1 layer together with the self-adhesive coating 4 has a cutout 9 around the periphery of each protrusion 7 and allows the individual nail stickers 8 together with the self-adhesive coating 4 to be separated from the base layer 5. The package comprises two identical kits, one for each hand or foot.
[0068] To use the sticker according to the invention, the kit is removed from the packaging and cleaned by degreasing the nail plate. Then, among the available protrusions 7, the protrusion that best matches the anatomical shape of the user's specific nail plate is selected. Untie the selected sticker 8 from the base layer 5. The untied sticker 8 is curled to the other side while maintaining its three-dimensional shape. The sticker 8 is placed on the nail plate starting from the nail crescent. Curl back when applying the sticker to restore its initial shape. The stickers form the anatomical nail shape, so they perfectly cover the entire nail plate. File off the excess sticker so that its length matches the length of the nail. The stickers 8 permanently imitate the natural shape of the nail and do not fall off easily. Due to their elasticity, they adapt perfectly to the shape of the nail. Fig. 9 a— Fig. 9 g shows the various stages of applying the sticker to the nail plate.
[0069] Example 2: A similar kit as in Example 1 is provided, but the same common base layer 5 has two kits 8 , each having a protrusion 7 .
[0070] Example 3: A similar kit to Example 1 is provided, but the protrusions 7 are cut away together with the base layer 5, leaving a flat connecting strip 10 connecting the protrusions 7, and the package includes two identical kits 8, each having a protrusion 7.
[0071] Example 4: A similar kit as in Example 2 is provided, but the protrusions 7 are cut away together with the base layer 5, leaving a flat connecting strip 10 connecting the protrusions 7.
[0072] Example 5: A similar kit as in Example 1 is provided, but the protrusion 7 is cut away together with the base layer 5 and the packaging comprises two identical kits 8 , each having a protrusion 7 .
[0073] Example 6: The formation of the sticker according to Examples 1 to 5 can be carried out using a mechanical forming method by hot or cold pressing (stamp + substrate). Other foils can also be used, such as LDPE (linear low-density polyethylene), PET (polyethylene terephthalate), APET or PLA (polylactic acid).
[0074] HIPS (high impact polystyrene), PET, PETG (PET with ethylene glycol), PMMA (poly(methyl methacrylate)), ABS (acrylonitrile butadiene styrene terpolymer), poly(acrylonitrile-butadiene-co-styrene), resin, natural rubber, rubber, silicone, silicone-coated pulp may also be used.
[0075] Example 7: A kit similar to Example 1 is provided, but the polyvinyl chloride foil 1 with a thickness of 60 μm does not comprise a decorative overprint 2 and is not covered with a protective layer 3. On one side, the foil 1 is covered with a self-adhesive coating 4 of an acrylic copolymer with the addition of piroctone olamine as an antifungal substance.
