Description

Technical Field

[0001] The present invention relates to the structure of false nails. Specifically, it relates to the structure of false nails in which a nail body provided with a watermark engraving is joined via a spacer.

[0002] False nails are formed by joining a nail body to the surface of the wearer's fingernail via an adhesive. Conventional false nails often prepare a plurality of types of nail bodies with different sizes and shapes, and select and join the nail body according to the size and shape of the wearer's fingernail.

[0003] The above nail body is joined to the fingernail via an adhesive, but the fingernail grows constantly, and the joining position of the false nail shifts. Moreover, the growth rates of the tip side and the base end side of the fingernail are different. Also, since the surface form of the fingernail itself changes, even if no stress acts during joining, over time, the strain of the nail body and the acting stress increase. For this reason, not only does the appearance deteriorate, but the joining strength also decreases, and the wearing period is at most about several weeks. Therefore, usually, false nails are often used once and then discarded.

[0004] Conventionally, various decorations are applied to false nails, and many are additionally provided on the surface of the false nails like painting.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Common methods for decorating nails include painting the surface or creating raised or recessed decorations, although these decorations are often added later. In some cases, glass decorative accessories are attached to the surface of the nail. Furthermore, it is also possible to create raised or recessed patterns integrally on the nail itself using molds or other methods.

[0007] It is conceivable to add openwork decoration to the nail body. Openwork decoration generally refers to decoration that has perforations created by cutting out a design from a plate material. In the present invention, openwork decoration refers not only to decoration consisting only of design perforations, but also to decoration that includes the above-mentioned perforations and other decorative forms of the plate material such as raised and recessed patterns. Openwork decoration is a form that has not been seen in conventional artificial nails and has been desired for a long time because of its high aesthetic effect. However, since the nail body is formed from a plate-like material with a small thickness, openwork is a kind of notch. next It is clear that the strength will decrease. In particular, the materials used for nail bodies have mostly been made of resin, and their strength is greatly reduced when openwork is added. In addition, many of the resin materials used so far have low hardness, making it difficult to form highly precise openwork decorations.

[0008] In particular, when post-processing openwork using methods such as manual or laser processing, if the strength and hardness of the material are low, it becomes difficult to create highly accurate openwork, and depending on the form of the openwork, there is a risk that the bonding strength to the fingernail cannot be ensured. In particular, if a nail body with openwork decoration is directly bonded to the fingernail using conventional methods, deformation is likely to occur as the fingernail grows, and there is a possibility that it will peel off the fingernail in a short period of time. Furthermore, if the amount of deformation of the nail body is large, irregularities may appear in the openwork area, which may damage the wearer's fingers or objects that come into contact with it. On the other hand, if a material with higher strength and hardness than resin, such as metal, is used, it may inhibit the growth of the fingernail as described above, potentially causing deformation or cracking of the fingernail.

[0009] Furthermore, creating openwork designs on artificial nails is time-consuming and costly. Therefore, if expensive materials are used, it may become difficult to treat the nail itself as disposable.

[0010] The present invention was devised to solve the above-mentioned problems, and aims to provide a structure for artificial nails that can reliably and safely attach a nail body with openwork to a fingernail, thereby solving the above-mentioned conventional problems. [Means for solving the problem]

[0011] The structure of the artificial nail according to the present invention is such that the surface of the fingernail It is attached and has a frame-like portion that follows the edge of the fingernail. It comprises a spacer and a plate-shaped claw body attached to the surface of the spacer. The claw body is decorated with openwork, and the claw body is attached to the spacer The above frame-shaped part It is joined to the fingernail via the above-mentioned part.

[0012] Generally, to create intricate and highly precise openwork decorations on small areas like artificial nails, it is desirable to use a thin plate material. However, thinner materials have lower strength. Therefore, it is necessary to form the material from a material that is stronger and harder than conventional nail materials. Moreover, even if no stress acts on a nail made from a hard material at the time of attachment, stress increases as the fingernail grows. This stress acts on the joint with the fingernail, making it difficult to ensure sufficient joint strength over a long period, and the wearing period becomes shorter compared to conventional nails.

[0013] In the present invention, the claw body provided with the above-mentioned openwork decoration is the same as It has a frame-like portion that follows the edge of the fingernail. It is attached to the fingernail via a spacer. Since the nail body is not directly attached to the user's fingernail, even if the nail body has dimensions or a shape that would prevent it from being directly attached to the fingernail, it can be attached to the fingernail as described above. High strength It becomes possible to join them together. especially, Adhesive surface that can be attached to fingernails of different dimensions and shapes It has a (back surface) and can bond a claw body of one dimension to the surface. If you prepare multiple spacers, The above-mentioned dimensional formThis makes it possible to attach the nail body to fingernails of different dimensions and shapes. Moreover, the manufacturing cost of a nail body with openwork decoration is far greater than the manufacturing cost of a spacer, and also greater than the manufacturing cost of a conventional nail body. In the present invention, a nail body of one dimension can be attached to fingernails of various dimensions and shapes, so the overall manufacturing cost does not increase significantly.

[0014] Artificial nails are often designed to extend from the tip of the fingernail. The openwork decoration of this invention is most effective when applied to this extended portion. Therefore, it is desirable to construct the nail body with an extended portion that extends from the fingernail, and to apply the openwork decoration to at least this extended portion. Even if the openwork decoration is applied to the portion overlapping the fingernail, the spacer surface... or the surface of the fingernail Because a textured pattern is formed that allows the viewer to see through the openwork opening, an unprecedented aesthetic effect can be achieved. Furthermore, if the surface of the spacer or the surface of the nail body is colored, the colored portion can be seen through the openwork opening, resulting in an unprecedented aesthetic effect.

[0015] The above-mentioned spacer can have a shape on the underside that corresponds to the surface morphology of the fingernail, and a shape on the surface that corresponds to the underside morphology of the nail body. By using a spacer with the above configuration, the nail body can be joined to the fingernail without deforming it. As a result, sufficient bonding strength can be ensured. Furthermore, if the spacer is made of a material that is more easily deformed than the nail body, the deformation (displacement) and stress caused by the growth of the fingernail can be mitigated.

[0016] In particular, with conventional artificial nails, a large amount of stress is often applied to the user's fingernails, which can deform or cause the fingernails to crack. In the present invention, the above spacer By making it into a frame shape This reduces the rate of increase in stress acting on the fingernails, thereby mitigating deformation and cracking of the fingernails. moreover, If the spacer is formed from a material that is more easily deformed than the claw body, the spacer will absorb deformation and stress, thus solving the problem. moreoverThis can be mitigated. This reduces the adverse effects on the fingernails and prevents a shortening of the period during which the nail can be attached. Furthermore, The shape of the attachment area to the nail can also be formed in a way that can alleviate the deformation and stress on the nail. For example, by intermittently providing joints at predetermined intervals, the contact area between the spacer and the fingernail can be reduced, and if stress that would cause the fingernail to crack is applied, some of the joints can be released. Furthermore, even if a material with high strength and hardness, such as a metal or ceramic material, is used, the spacer can alleviate the strain and stress that occurs between the fingernail and the nail, thereby mitigating deformation and cracking of the fingernail.

[0017] The form of the above-mentioned spacer is not particularly limited. That is, various forms can be used as long as the required bonding strength can be ensured with adhesive. The dimensions of the back side of the spacer are set to correspond to the dimensions of the fingernail to which it is attached. On the other hand, the dimensions of the front side of the spacer can be set to correspond to the dimensions of the back side of a specific nail. Specifically, multiple spacers are prepared, each having a common front side dimension to which a specific nail with openwork decoration can be attached, as well as different back side dimensions (fingernail side dimensions). One of the above-mentioned spacers that fits the user's fingernail can be selected and attached to the fingernail, and the specific nail can be joined to the fingernail via the spacer.

[0018] In the present invention, Place the above spacer at least on the edge of the fingernail or nail body. It is constructed with a frame-like section that follows the contours. The shape along the edge of the claw If a spacer is used, In the inner part, The above fingernail and the above nail body A gap will be created between them, but this gap can be left as is or filled with a resin filler or the like. Also, The frame-shaped spacer described above can be configured to be attached to the entire circumference or a portion of the edge of the fingernail surface.

[0019] The material of the spacer is not particularly limited, but it is preferably made of a material that is more easily deformed and has a lower hardness than the material constituting the claw body. For example, when the claw body is formed from a metal material or a ceramic material, the spacer can be formed from a resin material. Further, when both the claw body and the spacer are formed from a resin material, it is preferable that the material constituting the spacer is formed from a material having a lower hardness and strength than the material constituting the claw body. For example, while the claw body is formed from a polycarbonate resin or a hard polyethylene resin, the spacer can be formed from a vinyl chloride resin, an ABS resin, or the like. Even when the spacer is formed from the same resin material as the claw body, it can be configured to be easily deformed depending on the form of the claw body or the spacer. For example, concavities and convexities or grooves can be provided on the front and back of the spacer to adopt a form that is easily stretchable in the plane direction. For example, by providing grooves in a direction orthogonal to the growth direction of the fingernail at predetermined intervals, it becomes easier to absorb the displacement in the elongation direction of the fingernail. Also, a spacer having a porous or mesh-like form can be adopted.

[0020] It is preferable to set the thickness of the spacer to be larger than the thickness of the claw body. More preferably, it is preferable to set the thickness of the spacer to be 1.5 times or more the thickness of the claw body. Thereby, even when a hard material that is difficult to deform is adopted for the claw body, the spacer can absorb the stress and strain generated by the growth of the fingernail, relieve the deformation of the fingernail, etc., and prevent the wearing life of the artificial nail from being shortened.

[0021] The material constituting the claw body is not particularly limited. For example, it can be formed from a hard resin material, a ceramic material, a metal material, or the like. When the claw body is formed from a resin material, it is preferably formed from a hard resin material capable of forming a highly accurate embossed pattern. For example, polycarbonate resin, hard polyethylene resin, or the like can be adopted. When providing a highly accurate embossed pattern, it is preferable to adopt a plate material having a higher hardness and a smaller thickness than conventional resin materials.

[0022] Furthermore, when the above-mentioned claw body is formed from a metal material, high hardness allows for the formation of highly precise openwork. However, as the thickness of the metal material decreases, its shape retention decreases, and it may become difficult to ensure the shape retention strength of the claw body. In the present invention, since the above-mentioned spacer can be used as a shape-retaining material for such a claw body, it becomes possible to form the claw body from metal plates of small thickness that could not be used as claw bodies in the conventional method. For example, openwork decoration nail body Located in the center, nail body A frame-shaped spacer can be used along the edge. If this configuration is adopted, A spacer designed to reinforce the underside of the part of the claw body that does not have openwork carving. This is the result. Furthermore, when the nail body extends from the fingernail, the spacer can also be extended from the fingernail to reinforce the extended nail body on the back side. In this case, it is preferable that the spacer extends from the fingernail in a form that follows at least the edge of the nail body. Alternatively, the spacer can be attached to the entire back surface with the openwork, and the openwork portion of the spacer can be post-processed with a router or the like to create an opening, thereby forming an openwork on a laminated body in which the nail body and spacer are integrated.

[0023] The method for forming the openwork on the claw body described above is not particularly limited. For example, it can be formed by hand using various hand tools. In this case, various materials such as metal, ceramic, and resin can be used. Alternatively, resin or metal can be molded using a mold. Furthermore, it can be formed by laser processing on a plate.

[0024] Furthermore, while there are no particular limitations on the thickness of the nail body, it is preferable to form it from a thinner material than that used for conventional nail bodies in order to achieve highly precise openwork. The openwork can be applied to the entire nail body or only to the portion extending from the fingernail. If the cutout portion of the openwork decoration is located at the edge, the strength of the nail body may be significantly reduced, or it may catch on objects. In such cases, the spacer can be extended from the back of the edge, or the edge can be reinforced with a separate reinforcing material, and the cutout portion can be filled with UV-curing resin or the like.

[0025] On the other hand, when providing openwork on the portion opposite to the fingernail, it is preferable to provide the spacer in a portion that avoids the opening of the openwork so that the opening of the openwork is visible. Even if the spacer is provided so as to cover the opening of the openwork, a step difference will be created between the openwork portion and the spacer portion, thus providing a certain aesthetic effect. Furthermore, if a colored spacer is used, the colored surface of the spacer can be seen through the opening of the openwork, thus creating a kind of cut-out decorative pattern. In this case, it is preferable to join the nail body and the spacer with an adhesive or the like in the portion that avoids the opening.

[0026] An opening can be formed on the inside of the spacer, and an opening corresponding to the opening can be formed in the claw body. For example, when the frame-shaped spacer is used, the opening can be formed on the inside of the spacer attachment portion. Various decorations can be provided in the opening. For example, a resin filler can be filled in and a painted decoration can be applied to the surface. Alternatively, decorative members such as glass can be embedded in the resin filler. Since there is space between the opening and the thickness of the claw body and the spacer, the decorative member can be provided without protruding significantly. The position and form of the opening are not particularly limited.

[0027] Furthermore, the joining positions (adhesion positions) between the fingernail, the spacer, and the nail body do not necessarily have to coincide. In other words, the attachment position of the spacer to the fingernail and the attachment position of the spacer to the nail body do not need to coincide. The joining (adhesion) can be performed at the optimal location depending on the shape of the openwork, the strength of the spacer, the shape of the filling resin material, etc. [Effects of the Invention]

[0028] The structure of the artificial nail according to the present invention allows for the secure attachment of nail bodies with openwork designs made from various materials to the fingernails. Furthermore, it enables the creation of artificial nails with unprecedented aesthetic effects. [Brief explanation of the drawing]

[Figure 11] This is an exploded perspective view of a third embodiment of the artificial nail according to the present invention. Embodiment

[0030] Embodiments of the present invention will be described below with reference to the drawings. As shown in Figures 1 and 2, the structure of the artificial nail according to this embodiment comprises a nail body 1 that is joined to the fingernail 3 of a finger 4, a spacer 2 that is placed between the fingernail 3 and the nail body 1, and an adhesive layer (not shown) that joins these members. Note that the adhesive layer can be the same as the adhesive used to join conventional artificial nails, so its description and illustration are omitted.

[0031] The material constituting the above-mentioned claw body is not particularly limited. When a resin material is used for the above-mentioned claw body 1, it is preferable to use a resin material with higher strength and hardness than conventional resin materials. For example, it is preferable to use hard resins such as polycarbonate resin, acetate resin, polyphenylsulfone, polyamide, and polyetherimide. In particular, when forming openwork by machining, the thickness of the claw body is small, so it is necessary to use a hard material in order to create highly accurate openwork.

[0032] The claw body 1 according to this embodiment is formed by creating a perforation 5 on a flat plate-shaped resin material by press molding or the like, then performing curved shaping according to the shape of the surface side of the spacer 2, and punching it out in the shape of a claw. However, the method of forming the claw body 1 is not limited to this. For example, a claw body 1 in the shape of a fingernail without the perforation can be prepared, and the perforation can be created by hand using a router or the like. Alternatively, a perforation can be created on a flat plate member by laser processing or the like, and then it can be formed by press molding, heat setting it into the curved shape of a fingernail, and punching it out.

[0033] Furthermore, when forming from metal materials, openwork can be created by hand on the nail body shaped into a fingernail form. Alternatively, the nail body with the openwork can be integrally formed by forging or metal injection molding.

[0034] The spacer 2 described above has its back side formed to match the surface shape of the user's fingernail, while its front side is formed to match the back shape of the nail body 1. Since the spacer 2 is not exposed to the surface, it can be made of inexpensive resin. Therefore, multiple types of spacers corresponding to different fingernail shapes can have a common surface shape that corresponds to the back shape of a specific nail body. It is possible to select a spacer with a back shape that matches the shape of the user's fingernail and attach it to the fingernail, and to join a specific nail body 1 to a fingernail 3 of a different shape via the spacer 2. Furthermore, by attaching it via the spacer 2, it becomes possible to form a nail body from expensive materials that have not been used before, and to reuse this nail body 1 by replacing the spacer 2. For example, it becomes possible to use a nail body made of precious metals such as platinum.

[0035] In this embodiment, the spacer 2 is formed in a frame shape along the edge of the fingernail 3. The nail body 1 extends from the tip of the fingernail 3, and the openwork decoration 5 is formed avoiding the area where the spacer 2 is attached. As a result, the openwork portion of the nail body 1 that extends from the fingernail 3 allows visibility through to the opposite side, while the portion facing the fingernail 3 is configured to allow a gap corresponding to the thickness of the spacer to be seen through to the surface of the fingernail 3.

[0036] By adopting the above configuration, it is possible to obtain unprecedented decorative effects and securely hold the nail body 1 on the fingernail 3.

[0037] Figures 5 to 8 show a second embodiment of the present invention. In the second embodiment, an opening 22 corresponding to the opening 6 of the spacer 2 is formed at the base end of the claw body 21, and the openings 6 and 22 of the claw body 21 and the spacer 2 are filled with ultraviolet curing resin 23, and a glass decorative accessory 24 is embedded in this opening. As shown in Figure 8, in this embodiment, a resin layer with a thickness corresponding to the thickness of the claw body 21 and the spacer 2 can be formed, so the decorative accessory 24 can be held securely. Furthermore, since the decorative accessory can be held without protruding significantly from the surface of the claw body 21, it is aesthetically pleasing, and it is not only possible to prevent it from coming off by contact with an object, but it is also highly safe.

[0038] Figures 9 and 10 show a third embodiment of the present invention. In this embodiment, the nail body 31 extends from the tip of the fingernail 3, and the spacer 32 extends from the back surface of the extended portion 31a of the nail body 31, thereby creating a reinforcing structure that backs up the extended portion 31a of the nail body 31.

[0039] In this embodiment, a frame-shaped extension 31a is provided on the tip side of the spacer, along the edge of the claw body. This increases the strength of the claw body 31. In addition, the extension 31a of the claw body 31 is decorated with openwork ornamentation on the part excluding the edge that is attached to the extension 36 of the spacer 32.

[0040] By adopting the above configuration, the required shape-retaining strength can be secured even when forming the claw body 31 from a material with low thickness and poor shape retention.

[0041] The nail body can be formed using various methods. For example, a continuous openwork pattern can be created on a flat plate, and this can be punched out to fit the shape of a fingernail, and then curved to form the nail body. In this case, as shown in Figure 11, the notched portion 51 of the openwork decoration may be located on the edge of the nail body 41. In such a case, if the notched portion 51 comes into contact with the user's skin or objects, it could be dangerous.

[0042] In the embodiment shown in Figure 11, the spacer 42 is provided on the entire back surface of the claw body 41 including the notch 51, and the notch 51 is filled with ultraviolet-curing resin, and the edges are smoothly ground. This makes it possible to avoid the above-mentioned problems even when the notch 51 is located at the edge.

[0043] Furthermore, in this embodiment, the spacer 42 is attached to the entire back surface of the claw body 41, and the portion of the spacer 42 with the openwork decoration 5 is removed using a router or the like, thereby forming the openwork decoration 5 on the integrated laminate of the claw body 41 and the spacer 42. The removal of the spacer 42 can be performed while ensuring the required strength because the claw body 41 is laminated. As a result, even if the hardness of the spacer 42 is low, it is possible to post-process the openwork on the spacer 42 with high precision.

[0044] The scope of the present invention is not limited to the embodiments described above. The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims, not in the sense described above, and all modifications within the sense and scope equivalent to the claims are intended to be included.
