Description

  The present invention relates to an artificial nail patch that is provided between an artificial nail and the self nail when the artificial nail is affixed to a user's own nail, a method for manufacturing the same, and a method for using the same.

  Recently, nail art is prevalent among women. This is a fashion that can be enjoyed as a fashion by putting pictures, characters and flat decorative items such as pressed flowers, fine stones, and color powder on the nails.

  Also, people who want to enjoy nail art in the past, but who can't do nail art because their own nails are weak, they break when stretched, their nails are deformed, or they cannot stretch their nails in daily life And artificial nails have been developed for those who want to show nail art more beautifully.

  For example, an artificial nail called a sculpture is obtained by applying an acrylic resin mixed with acrylic powder and monomers into a gel and applying it on the nail, shaping it with a brush or writing, and then curing it. is there. However, the above-described artificial nail (sculpture) has the following problems.

  First, as a problem when shaping the artificial nail into a self nail, the surface of the self nail is shaved with a file in order to improve the adhesion between the artificial nail and the self nail, so that the self nail becomes gradually thinner. In addition, there has been a problem that is unfavorable to health, such as the vapor of acrylic resin diffused into the air during shaping, being inhaled into the body from the respiratory organs of the user or practitioner. Furthermore, the treatment required a long time of at least 2 to 3 hours.

  Moreover, as a problem after shaping the artificial nail, a fill-in process for filling a gap with the newly grown nail was required once every two to three weeks. In addition, the nails and the nail mother side are likely to remain floating, and water or the like enters the gaps, causing mold and causing nail disease.

  Further, as a problem when removing the artificial nail from the self nail, there is no other way than removing the artificial nail by external force or immersing the artificial nail in acetone or the like. For this reason, when the artificial nail is shaved, there is an unfavorable health problem that the acrylic resin powder scattered in the air is inhaled from the respiratory organs of the user or practitioner. In addition, when the artificial nail is immersed in acetone or the like, the self-nail or skin must be considerably damaged by the acetone or the like.

  Therefore, an artificial nail called a chip nail is known. For this artificial nail, a plurality of artificial nails previously shaped into a predetermined shape are prepared, and an artificial nail that best matches the shape of the user's own nail is selected from the artificial nail, and the artificial nail is automatically attached via a double-sided tape. Affixed to the nail (see Patent Document 1).

JP2004-254877

  However, the double-sided tape used when attaching the artificial nail to the own nail generally has a sheet-like base material layer at the center in the thickness direction, and the base material layer is hard to bend due to its rigidity. For this reason, it was difficult for the double-sided tape to sufficiently follow the surface of the curved nail. For this reason, when the artificial nail is affixed to the nail, the double-sided tape is wrinkled, and this wrinkle is visually recognized from above the artificial nail, so that the appearance when the artificial nail is attached to the nail is impaired. It was.

  The present invention has been made in view of the above-described technical background, and provides an artificial nail patch capable of neatly attaching an artificial nail to a user's own nail, a method for manufacturing the same, and a method for using the same. For the purpose.

  In order to achieve the above object, the present invention is an artificial nail patch provided between an artificial nail and the self nail when the artificial nail is affixed to the user's own nail, and is provided on one side. A first pressure-sensitive adhesive layer; a second pressure-sensitive adhesive layer provided on the other side; a gel-like base material layer provided between the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer; It is characterized by providing.

  According to this, since the gel-like base material layer is easily curved, the artificial nail patch sufficiently follows the curved nail surface. For this reason, wrinkles do not occur in the artificial nail patch, so that the artificial nail can be neatly adhered to the own nail.

  In addition, a first release material is provided on the surface of the first pressure-sensitive adhesive layer opposite to the base material layer, and the second pressure-sensitive adhesive layer has a second surface on the surface opposite to the base material layer. A release material is preferably provided. According to this, the artificial nail can be easily attached to the own nail by peeling the first release material and the second release material from the artificial nail patch.

  The first pressure-sensitive adhesive layer, the second pressure-sensitive adhesive layer, and the base material layer are preferably made of a transparent material. According to this, since the adhesive material for the artificial nail becomes transparent, the artificial nail can be seen through the artificial nail when the artificial nail is attached to the own nail. It can have a natural pink appearance like a self nail.

  The first pressure-sensitive adhesive layer and / or the second pressure-sensitive adhesive layer is preferably made of a gel-like silicon pressure-sensitive adhesive. According to this, since the silicone-based adhesive does not contain a liquid organic solvent and is hypoallergenic, it can prevent the organic solvent from infiltrating into the user's body and the occurrence of allergic symptoms in the user. it can. In addition, since this silicone adhesive has flexibility and its adhesiveness decreases when immersed in hot water at a predetermined temperature (for example, 45 ° C. or higher), the user can put the artificial nail on the self nail. By soaking in hot water at a predetermined temperature (for example, 45 ° C. or higher), the artificial nail can be easily removed without damaging the nail. Moreover, since this silicone adhesive has water resistance, the user can do hand-washing or water work in a state where the artificial nail is attached to the own nail.

  Moreover, it is preferable that the said base material layer consists of photocurable resin. According to this, a gel-like base material layer having an appropriate softness and thickness can be provided easily and reliably.

  The base material layer preferably has a viscosity of 2270 Pa · S to 6170 Pa · S. According to this, since the gel-like base material layer has appropriate softness, the artificial nail patch can reliably follow the surface of the curved nail.

  Moreover, the manufacturing method of the adhesive material for artificial nails which concerns on this invention peels one release material from the 1st double-sided adhesive tape in which the release material was provided in the both sides of the adhesive layer, and is the 1st double-sided adhesive tape. The step of exposing the pressure-sensitive adhesive layer as the first pressure-sensitive adhesive layer, and providing the gel-like base material layer on the exposed first pressure-sensitive adhesive layer, the base material on the first pressure-sensitive adhesive layer. A step of laminating the layers, a release material on one side is peeled from a second double-sided pressure-sensitive adhesive tape provided with a release material on both sides of the pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer of the second double-sided pressure-sensitive adhesive tape is removed from the second pressure-sensitive adhesive layer. The step of exposing as an adhesive layer and the exposed second adhesive layer are adhered to the base material layer, whereby the first adhesive layer, the base material layer and the second adhesive layer are And a step of sequentially laminating. According to this, the artificial nail patch can be easily and reliably manufactured.

  In addition, the method for using the artificial nail patch according to the present invention includes peeling the first release material from the artificial nail patch and exposing the exposed first adhesive layer to the surface of the user's own nail or artificial. After sticking on the back surface of the nail, peeling the second release material from the adhesive material for artificial nail and sticking the exposed second adhesive layer to the back surface of the artificial nail or the surface of the artificial nail, The artificial nail is affixed to the user's own nail via an artificial nail adhesive. According to this, the artificial nail can be easily and reliably attached to the own nail.

  According to the present invention, since the gel-like base material layer is easily curved, the artificial nail patch sufficiently follows the curved nail surface. For this reason, wrinkles do not occur in the artificial nail patch, so that the artificial nail can be neatly adhered to the own nail.

  In addition, by adjusting the thickness of the gel-like base material layer, the thickness, hardness and flexibility of the artificial nail patch can be adjusted freely, and the product lineup of artificial nail patches is rich. It is also possible to do.

  Moreover, when attaching an artificial nail to a self-nail, since it is not necessary to scrape the surface of a self-nail with a file, the problem that a self-nail becomes thin gradually can be solved. Even when the practitioner attaches the artificial nail to the nail, the dominant hand can be easily performed alone. Furthermore, since the acrylic resin vapor does not diffuse into the air, there is no problem that the user or practitioner inhales the acrylic resin vapor. Furthermore, the treatment can be completed in a short time without requiring a long time of 2-3 hours.

  In addition, since it is not necessary to attach the artificial nail to the nail for a long period of time such as 2 to 3 weeks, a gap with the newly grown nail does not occur and a fill-in process is unnecessary. Further, since the nail and the nail mother side do not remain floating, there is no problem that mold or the like is generated due to water entering the gap.

  Further, when the artificial nail is removed from the own nail, the artificial nail can be easily removed without damaging the own nail by immersing the finger in hot water with the artificial nail attached to the own nail.

  Therefore, the user of the artificial nail patch can easily and safely decorate his / her nails with artificial nails at any time, and can enjoy nail art more routinely.

  In the first pressure-sensitive adhesive layer 11, the first release material 101 provided on the surface 11 a opposite to the base material layer 13 is peeled off, and the exposed surface 11 a is attached to the nail N. The first pressure-sensitive adhesive layer 11 is made of a gel-like silicon pressure-sensitive adhesive having a uniform thickness of, for example, 0.2 mm to 0.4 mm and having viscosity. For this reason, since the silicon-based adhesive does not contain a liquid organic solvent and is hypoallergenic, it is possible to prevent the organic solvent from infiltrating into the user's body and allergic symptoms from occurring in the user. Moreover, since this silicone adhesive has flexibility and its adhesiveness decreases when immersed in hot water at a predetermined temperature (for example, 45 ° C. or higher), the user stuck the artificial nail A to the self nail N. The artificial nail A can be easily removed without damaging the own nail N by immersing in hot water at a predetermined temperature (for example, 45 ° C. or higher) in the state. Moreover, since this silicone adhesive has water resistance, the user can do hand washing or water work in a state where the artificial nail A is attached to the self nail N. In addition, the 1st adhesive layer 11 is not limited to a silicon-type adhesive, For example, other adhesives, such as an acrylic adhesive, may be sufficient.

  In the second pressure-sensitive adhesive layer 12, the second release material 201 provided on the surface 12 b opposite to the base material layer 13 is peeled off, and the exposed surface 12 b is attached to the artificial nail A. Since the second pressure-sensitive adhesive layer 12 has the same material, thickness, and adhesive force as those of the first pressure-sensitive adhesive layer 11, description thereof will be omitted.

  The base material layer 13 is laminated on the surface 11 b of the first pressure-sensitive adhesive layer 11 by applying a gel-like material to the surface 11 b on the other side of the first pressure-sensitive adhesive layer 11. In this embodiment, since the front base material layer 13 consists of gel-like photocurable resin, the gel-like base material layer 13 of moderate softness and thickness can be provided easily and reliably.

  The base material layer 13 has a viscosity of, for example, 2270 Pa · S to 6170 Pa · S. For this reason, when the gel-like base material layer 13 has appropriate softness, the patch 1 can reliably follow the surface of the curved nail N.

  The base material layer 13 has a uniform thickness of 0.2 mm to 0.9 mm, for example. Therefore, the patch 1 has an appropriate thickness and solidity, and the patch 1 can be easily processed and handled. In addition, by adjusting the thickness of the base material layer 13, the thickness of the patch 1 can be freely adjusted, and the product lineup of the patch 1 can be enriched.

  Moreover, the 1st adhesive layer 11, the 2nd adhesive layer 12, and the base material layer 13 consist of a transparent material. For this reason, since this patch 1 is transparent, the artificial nail N can be seen through the artificial nail A in a state where the artificial nail A is adhered to the natural nail N. Can have a natural pink appearance like the nail N.
