During use, the soft properties are utilized to adhere to the edge of the nail, reducing stretching and wrinkling, and also reducing the possibility of cavities, hollows, and lifting. After hardening, a hard state is formed, and the entire nail tip layer takes on a hard, plump shape to decorate the nail, resulting in a beautiful appearance.

[0020] 2.

[0021] 3. In the present application, the amount of hardening material corresponding to the rear edge and both side portions of the nail in the decorative nail tip is reduced, making the hardness slightly lower, so that the nail tip layer can be easily removed from the edge portion; and the amount of hardening material corresponding to the center and tip portions of the nail in the decorative nail tip is increased, making the hardness relatively high, so that the nail can be kept stable when decorated and is less likely to be distorted or cracked due to external forces.

[0022] 4.

[0024] The following describes the technical methods in the embodiments of the present application in conjunction with the drawings.

[0025] It should be understood that the specific examples in the present specification are intended to help those skilled in the art better understand the embodiments of the present application, and are not intended to limit the scope of the embodiments of the present application.

[0026] It should also be understood that in the various embodiments of the present application, the order number of each process does not mean whether it is executed earlier or later, and the order of execution of each process is determined by its function and inherent logic, and does not constitute any limitation on the implementation process of the embodiments of the present application.

[0027] It should also be understood that the various embodiments described herein may be implemented alone or in combination, and the embodiments of the present application are not limited thereto.

[0028] Unless otherwise explained, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art of this application. The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit the scope of this application. As used in this application, the term "and / or" includes any and all combinations of one or more of the associated items.

[0029] Embodiment 1 Embodiment 1 of the present application provides a decorated nail tip. Specifically, referring to Fig. 1, the decorated nail tip includes a nail tip layer 2, which is generally curved inward and has a shape and size similar to that of a human nail 1, and the concave inner surface of the nail tip layer 2, i.e., the inner surface, is used for attaching to the outer surface of a human fingernail or toenail (hereinafter collectively referred to as "nail 1"), and the convex outer surface of the nail tip layer 2, i.e., the outer surface, is formed as the decorative surface of the nail tip layer 2 and is used for decorating the nail 1.

[0030] The toe direction L of the nail tip layer 2 is defined as the direction toward the tip 1c of the nail 1 when the nail tip layer 2 is used to decorate the surface of the nail 1. In other words, it coincides with the growth direction of the nail 1. The nail tip layer 2 includes a soft seal portion 21 and a hard portion 22, which are arranged along the toe direction L. When applied to the surface of the nail 1, the soft seal portion 21 is in close contact with at least a portion of the rear edge 1a and the side edge 1b of the nail 1, and the hard portion 22 is in close contact with the tip 1c of the nail 1 or is arranged to extend beyond the tip 1c. The outer surfaces of the soft seal portion 21 and the hard portion 22 smoothly transition to form a decorative surface, so that when the surface of the nail 1 is decorated, the outer surface of the nail tip layer 2 has a rounded, plump shape.

[0031] The smooth transition mentioned here means that there is no step at the connecting portion of the outer surfaces of the soft seal portion 21 and the hard portion 22, and the connecting portion of the outer surfaces of both the soft seal portion 21 and the hard portion 22 transitions smoothly or smoothly.

[0032] In particular, the raw materials of the nail tip layer 2 in this embodiment contain a hardening material, and before use, the hardening material in the soft seal portion 21 is not hardened and is soft and stretchable overall, while the hardening material in the hard portion 22 has already hardened and is hard overall.

[0033] Compared with existing technologies, the decorative nail tip provided in this embodiment has the advantage of being soft on one end and hard on the other, thereby combining the advantages of flexible adhesion and hard orientation. The appearance formed when the entire nail tip layer 2 is attached to the nail 1 is close to the shape of a naturally growing nail 1 and the shape of commercially available false nails, and the structure of the entire nail tip layer 2 is plump, natural, and beautiful.

[0034] Specifically, when the decorative nail tip of the present application is applied to the surface of the nail 1, the flexible soft seal portion 21, due to its flexibility and good ductility, can fit the curved shape of the rear edge 1a of the nail 1 and adhere closely to the nail 1, and by further adhering the nail tip layer 2 to the rear edge 1a and side edge 1b of the nail 1, the occurrence of wrinkles, hollows, and gaps at the edges in the soft seal portion 21 of the nail tip layer 2 is reduced, and the soft seal portion 21 is fixed in a plump and smooth state to the rear edge 1a of the nail 1. When the soft seal portion 21 is then cured, the soft seal portion 21, which has been fitted and adhered to the rear edge 1a and side edge 1b of the nail 1, continues to fit and adhere to the nail 1 even after curing, thereby reducing the possibility of hollows, hollows, or lifting between the nail tip layer 2, which has been hardened overall after curing, and the nail 1. Because the connection structure between the soft seal portion 21 and the nail 1 is strong, the soft seal portion 21 is unlikely to lift up at the edge or fall off the nail 1, and there is also a reduced possibility of dirt accumulating between the soft seal portion 21 and the nail 1 or hair getting caught. The soft seal portion 21 of the nail tip layer 2 can be completely adhered to the rear edge 1a and side edge 1b of the nail 1, which reduces the thickness of the adhesive layer required when attaching the nail tip layer 2 to the surface of the nail 1, improving the breathability of the surface of the nail 1 and also reducing the amount of adhesive material used in the adhesive layer and the damage caused to the nail 1 by the adhesive material in the adhesive layer.

[0035] Furthermore, when the decorative nail tip of the present application is applied to the surface of the nail 1, the hard portion 22 can be fitted to the curvature of the nail 1 by utilizing its convex curvature, making it easy for the user to apply the decorative nail tip to the surface of the nail 1 and simplifying the steps for using the decorative nail tip. By forming the hard portion 22 as the tip of the nail tip layer 2 with a hard, fixed shape and hardness, there is no need to trim or polish the edges of the nail 1 or the nail tip layer 2, resulting in a smooth, neat, and beautiful fingertip 1c. This reduces the steps for using the nail tip layer 2 and shortens the time required to apply the nail tip layer 2. At the same time, the nail tip layer 2 can hide and protect the fingertip 1c of the nail 1 by utilizing the hard portion 22, preventing the nail 1 from being exposed to air and being bent, broken, or torn by external forces.

[0036] Furthermore, in some examples of this embodiment, the length of the nail tip layer 2 is set to be longer than the length of the nail 1, and after the hard portion 22 is attached to the surface of the nail 1, it is extended from the fingertip 1c in a hard shape, thereby playing the role of lengthening the nail 1, improving the shape of the nail, and decorating the nail surface. Compared with the existing nail tip layer 2, the nail tip layer 2 designed in this manner of the present application can also play the role of increasing the area of ​​the nail surface and increasing the design space of the nail tip, helping designers to create more abundant and diverse shapes and designs on the nail surface.

[0037] 2, the thickness of the soft seal portion 21 at the portion connected to the hard portion 22 gradually decreases toward the edge of the soft seal portion 21 that is not connected to the hard portion 22. Because the thickness of the edge of the soft seal portion 21 at the portion not connected to the hard portion 22, i.e., the portion where the soft seal portion 21 connects to the rear edge 1a and side edge 1b of the nail 1, is relatively thin, the soft seal portion 21 is more flexible, and its flexibility and ductility are further improved. Since the soft seal portion 21 can be stretched to adhere to the rear edge 1a and side edge 1b of the nail 1, the occurrence of wrinkles, cavities, lifting, etc. is further reduced. Because the portion where the soft seal portion 21 connects to the rear edge 1a and side edge 1b of the nail 1 is relatively thin, the gap between the edge of the soft seal portion 21 and the rear edge 1a, side edge 1b, and fingertip 1c of the nail 1 is reduced, reducing the accumulation of dirt and preventing hair from getting caught. Furthermore, by providing the nail tip layer 2 that is thin at the edges and thick at the center, when the nail tip layer 2 is attached to the surface of the nail 1, a rounded and plump structure can be formed in which the rear edge 1a and side edges 1b of the nail 1 are thin and the center of the nail 1 is thick, thereby improving the beauty and glossiness of the nail tip layer 2 when decorating the surface of the nail 1.

[0038] Preferably, the thickness of the edge of the soft seal portion 21 where it connects with the hard portion 22 and the thickness of the hard portion 22 are between 0.05 and 2 mm, and the thickness of the edge of the soft seal portion 21 where it is not connected with the hard portion 22 is between 0.01 and 0.25 mm. This thickness range ensures the expression of the color and design at the part where the soft seal portion 21 connects with the rear edge 1a and side edge 1b of the nail 1, while at the same time providing sufficient flexibility, toughness, and ductility to adhere closely to the curved surface of the nail 1, thereby reducing the possibility of wrinkles, cavities, and lifting.

[0039] Furthermore, the soft-sealing portion 21 is generally U-shaped and surrounds the edge of the hard portion 22, with the bottom of the U-shape corresponding to the rear edge 1a of the nail 1. The two U-shaped side walls of the soft-sealing portion 21 correspond to both side edges 1b of the nail 1, making it easy to apply, and the hard portion 22 has a slightly pointed end that extends into the U-shaped groove of the soft-sealing portion 21. During use, the adhesive area between the hard portion 22 and the surface of the nail 1 is relatively large, which improves the structural strength when the entire nail tip layer 2 is applied to the surface of the nail 1 after the soft-sealing portion 21 hardens. Regardless of the size of the adhesive and fixing area between the soft-sealing portion 21 and the surface of the nail 1, as long as the edges of the soft-sealing portion 21 are ensured to fit tightly against the rear edge 1a and side edges 1b of the nail 1, no wrinkles or lifting will remain, thereby solving the problems encountered with decorative nail tips in existing technologies.

[0040] The width of the U-shape of the soft seal portion 21 is 0.1 to 5 mm, and more preferably, the width of the U-shape of the soft seal portion 21 is 1 to 2 mm. The relatively small width of the soft seal portion 21 makes the nail tip layer 2 easy to use and also ensures that the flexible shape at the edge of the nail tip layer 2 allows it to be tightly adhered and fixed to the surface of the nail 1.

[0041] Furthermore, the content of the hardening material in the raw material of the edge of the soft seal portion 21 not connected to the hard portion 22 is less than the content of the hardening material in the raw material of the edge of the soft seal portion 21 connected to the hard portion 22. More specifically, the content of the hardening material in the soft seal portion 21 gradually increases from the edge of the portion not connected to the hard portion 22 to the edge of the portion connected to the hard portion 22. By setting it in this manner, when the nail tip layer 2 is attached to the surface of the nail 1 and the hardening material in the soft seal portion 21 is hardened, the hardness of the center of the nail tip layer 2 is increased, and the nail tip layer 2 in its hard state is less likely to be distorted, deformed, or torn by external forces. Because the edge of the nail tip layer 2 has a lower hardness, it is easier to remove the nail tip layer 2 by lifting it from this edge. Furthermore, before the soft seal portion 21 is hardened, the hardness of the soft seal portion 21 and the hard portion 22 gradually increases and transitions gently, so that when the entire nail tip layer 2 is peeled off, relatively uniform tensile deformation and shrinkage can be generated in the nail tip layer 2, and the entire nail tip layer 2 after hardening can be made plump and rounded, glossy, and tough.

[0042] The curable material in this embodiment may be one or more of a heat curable material, a UV curable material, a UV heat curable material, or an electron beam curable material, regardless of the curable material or curing method, and may also contain an initiator arranged according to the type of solvent and curable material. When the initiator is activated under certain conditions, it stimulates the curable material to initiate a curing reaction, thereby curing the entire material.

[0043] In this embodiment, the uncured soft seal portion 21 has a Shore hardness of 20A to 60A, a tensile modulus of 1.5 to 5, and a tensile strength of 80MPa to 500MPa. In other embodiments of the present application, the relevant properties of the uncured soft seal portion 21 are preferably a Shore hardness of 25A to 45A, a tensile modulus of 3 to 4, and a tensile strength of 300MPa to 400MPa.

[0044] The cured soft seal portion 21 has a Shore hardness of 20D to 70D, a tensile modulus of 1.05 to 1.2, and a tensile strength of 100 MPa to 200 MPa. In other embodiments of the present application, the relevant properties of the cured soft seal portion 21 are preferably a Shore hardness of 30D to 50D, a tensile modulus of 1.1 to 1.3, and a tensile strength of 125 MPa to 150 MPa.

[0045] The hard portion 22 has a Shore hardness of 25D to 80D, a tensile modulus of 1.04 to 1.15, and a tensile strength of 90 MPa to 200 MPa. In other embodiments of the present application, the relevant properties of the hard portion 22 are preferably a Shore hardness of 40D to 60D, a tensile modulus of 1.1 to 1.12, and a tensile strength of 120 MPa to 150 MPa.

[0046] Thus, the uncured soft seal portion 21 has the properties of being flexible and having good ductility, and can maintain an airtight bond with the curved human nail 1, making it easy to reduce wrinkles and less likely to deform or break when pulled. The cured soft seal portion 21 has a relatively high hardness and relatively low ductility, similar to the properties of the hard portion 22, and is therefore hard like a jewel, and can decorate the surface of the human nail 1 with a plump shape, fulfilling its decorative role.

[0047] 3, in order to make the nail tip layer 2 easier to use, a base adhesive 3 is provided on the concave inner surface of the nail tip layer 2, and the nail tip layer 2 can be directly attached to the nail 1 using the base adhesive 3. If the base adhesive 3 is not provided, the nail tip layer 2 can be attached to the surface of the nail 1 using a single liquid adhesive, solid adhesive, or jelly adhesive.

[0048] When used with a short type nail tip layer 2, the base adhesive 3 is spread on the bottom of the nail tip layer 2, and when used with a long type nail tip layer 2, the base adhesive 3 is placed in the shape of a nail 1 at one end of the bottom of the nail tip layer 2 near the soft seal part 21.

[0049] When the nail tip layer 2 is installed as a multi-layer structure, the curing material is located in one or more layers of the multi-layer structure. Unlike many existing nail tip layers 2, which are installed as a single layer that is injection-molded after mixing raw materials, the nail tip layer 2 installed as a multi-layer structure has a stronger layered feel, can more appropriately embody the color and design of the nail tip layer 2, and is also useful for designing and improving the structure of the entire nail tip layer 2 in the layer structure. Installing it as a multi-layer structure increases the strength of the connection structure between the soft seal part 21 and the hard part 22, and can also reduce the problem of the connection part between the soft seal part 21 and the hard part 22 easily breaking due to the difference in curing time between the two parts.

[0050] Referring specifically to Figure 3, the nail tip layer 2 includes, from the concave inner surface to the convex outer surface, a bottom sealing layer 2a, a design layer 2b, a special effect layer 2c, a curing layer 2d, and a top sealing layer 2e, in that order, with the curing material located within the curing layer 2d. The bottom sealing layer 2a supports the bottom base layer and is preferably made of acrylic, polyurethane, polyester, or epoxy resin. The design layer 2b is printed on the isolation layer and can be produced by silkscreen printing, offset printing, digital printing, flexography, letterpress, or other printing methods. The special effect layer 2c is designed based on the desired effect of the decorative nail tip and can be made using glitter powder, pearl powder, aurora powder, fluorescent powder, thermochromic powder, or foil paper, and can be further applied by silkscreen printing, foil stamping, sprinkling, spraying, or other methods to create colorful, sparkling, special visual effects. The raw materials for the curing layer 2d include a UV-curable resin, a photoinitiator, and an environmentally friendly solvent. The curable layer 2d is liquid at room temperature, and when heated, a limited thermosetting reaction occurs as the solvent evaporates, and when cooled, it becomes a semi-solid latex state. At this time, the curable layer 2d has good flexibility and adhesiveness. When the curable layer 2d is irradiated with a UV lamp, the photoinitiator is activated, causing a photosetting reaction, which cures very quickly and forms a fixed shape.

[0051] In particular, the nail tip layer 2 further includes a hard toe portion 23, which is located at one end of the hard portion 22 farther from the soft seal portion 21 and coincides with the curvature direction of the hard portion 22, and the thickness of the toe portion 23 is equal to or greater than the thickness of the hard portion 22. In particular, as shown in Figure 3, the toe portion 23 is located between the special effect layer 2c and the hardened layer 2d, and the thickness of the nail tip layer 2 gradually increases from the hard portion 22 toward the toe portion 23.

[0052] To ensure the hardness and increase the toughness and strength of the toe portion 23, a hard support piece 24 is provided in the toe portion 23, which is arranged as shown in Figure 3. The support piece 24 is arranged in an openwork grid pattern, and the curvature direction of the support piece 24 is the same as that of the toe portion 23. The material of the support piece 24 may be plastic, resin, or metal.

[0053] In addition, in order to protect the nail tip layer 2 and prevent it from getting dirty, being deformed by being pulled, or leaving various marks before the user uses it, a protective film 2f is further installed on the surface of the nail tip layer 2, and the area of ​​the protective film 2f is larger than the area of ​​the nail tip layer 2 and covers the entire nail tip layer 2.

[0054] In particular, in order to maintain the approximate curved contour of the human nail 1 throughout the nail tip layer 2, the soft seal portion 21 of the nail tip layer 2 maintains its curved state under the action of an external substance, and the outer surfaces of the soft seal portion 21 and the hard portion 22 appear rounded and plump. In this embodiment, referring to FIG. 4, this external substance is a support piece 4, which is entirely hard and has a support block 41 shaped like the nail 1, and the convex outer surface of the support block 41 fits and joins with the concave inner surface of the nail tip layer 2. This provides support for the hard portion 22, reducing the possibility of distortion and even breakage of the hard portion 22 due to the application of external force. Furthermore, by providing shape and support to the soft seal portion 21 and the connecting portion between the soft seal portion 21 and the hard portion 22, it is possible to prevent wrinkles from occurring at the soft seal portion 21 and the connecting portion between the soft seal portion 21 and the hard portion 22, which would otherwise affect the aesthetics of the nail tip layer 2. At the same time, the arch-shaped support block 41 in the shape of the nail 1 has a relatively large supporting force, so by fitting and joining it with the concave inner surface of the nail tip layer 2, it can perform an even better supporting function than support blocks 41 of other shapes.

[0055] Embodiment 2 Embodiment 2 of the present application provides a manufacturing system for decorative nail tips, which is used to manufacture the decorative nail tips in embodiment 1, and the actual process or structure is similar to that of embodiment 1, but there are also differences. The following description focuses on the differences, and the detailed description of the other parts can be considered to be the same as embodiment 1, so they will not be repeated here.

[0056] 5, in this embodiment 2, the decorative nail tip manufacturing system includes a tip material molding device 5, a tip material curving device 6, and a curving and hardening device 7, which are connected in this order. The tip material molding device 5 is used to obtain a tip material in the shape of a flat nail 1, where the tip material is soft and extensible and the raw material of the tip material contains a hardening material. The tip material curving device 6 is used to curve the flat tip material, whose convex outer surface forms a decorative surface that matches the curvature of the surface of the nail 1. The curving and hardening device 7 is used to harden one end of the curved tip material.

[0057] Compared with existing technologies, the decorative nail tip manufacturing system provided in this embodiment uses a coordinated setup of different devices, allowing materials to be transferred between the various devices to perform the corresponding processes of flat tip molding, tip curvature molding, and nail tip layer 2 hardening, resulting in a nail tip layer 2 that is soft on one end and hard on the other. This simplifies the process and operation. As described in embodiment 1, the soft-on-hard nail tip layer 2 allows the nail tip layer 2 to flexibly adhere to the posterior and lateral edges 1a and 1b of the nail 1, thereby reducing the problems of wrinkles and lifting at the edges. Furthermore, the nail tip layer 2 can be applied to the fingertip 1c in a hard shape or can extend beyond the fingertip 1c, eliminating the need for processing or polishing the fingertip 1c to beautify it. The nail tip layer 2 is highly efficient and provides a superior user experience.

[0058] In particular, the chip material molding device 5 may be any one of a silk screen printing machine, a lithographic offset printing machine, a digital printing machine, a flexographic printing machine, an intaglio printing machine, and a letterpress printing machine, thereby forming flat chip material by any one of the methods of silk screen printing, lithographic offset printing, digital printing, flexographic printing, intaglio printing, and letterpress printing corresponding to the device.

[0059] Embodiment 3 Embodiment 3 of the present application provides a method for manufacturing a decorative nail tip, which is used to manufacture the decorative nail tip of embodiment 1 using the decorative nail tip manufacturing system of embodiment 2, and the actual process or structure is similar, but there are also differences.

[0060] In the third embodiment, referring to FIG. 6, a method for manufacturing a decorative nail tip includes: Step S1: forming a tip material in the shape of a flat nail 1, the tip material being flexible and extensible, and the raw material of the tip material containing a hardening material; Step S2: forming a flexible nail tip layer 2 by curving the flat tip material, the convex outer surface of the flexible nail tip layer 2 becomes a decorative surface that matches the curvature of the nail 1 surface; Step S3 is a step of performing a hardening operation on one end of the flexible nail tip layer 2, in which the hardened one end portion of the nail tip layer 2 forms a hard hard part 22, and the unhardened one end portion of the nail tip layer 2 forms a flexible and stretchable soft seal part 21; Includes:

[0061] The decorative nail tip manufacturing method provided in this embodiment involves sequentially forming a flat tip material from raw material, curving the tip material, and hardening the nail tip layer 2, resulting in a nail tip layer 2 that is soft on one end and hard on the other. This simple process and easy operation are essential. The soft-on-hard nail tip layer 2, as described in embodiment 1, allows the nail tip layer 2 to flexibly adhere to the posterior and lateral edges 1a and 1b of the nail 1, reducing the risk of wrinkles and lifting. Furthermore, the nail tip layer 2 can be applied to the fingertip 1c in a hard shape or can extend beyond the fingertip 1c, eliminating the need for processing or polishing to beautify the fingertip 1c. The nail tip layer 2 is highly efficient and provides a particularly excellent user experience.

[0062] In step S1, a chip material molding device 5 is used to form a flat nail-shaped chip material. Specifically, a silk screen printing machine, a lithographic offset printing machine, a digital printing machine, a flexographic printing machine, an intaglio printing machine or a letterpress printing machine is used, and the flat chip material is formed by adopting the techniques of silk screen printing, lithographic offset printing, digital printing, flexographic printing, intaglio printing and letterpress printing.
