Abstract
Description
Technical Field
[0001] This utility model relates to the field of nail art, specifically to a light-cured wearable nail. Background Technology
[0002] Existing wearable nails include a substrate used as the nail tip itself. In the actual nail art process, the operator applies UV-curing gel to the back of the substrate, attaches the coated substrate directly to the nail to be manicured, and then uses a UV lamp to irradiate the substrate from the front. The UV light emitted by the UV lamp penetrates the substrate and irradiates the UV-curing gel located between the substrate and the nail. After being irradiated, the UV-curing gel solidifies, thus fixing the wearable nail to the nail, completing the manicure for one nail. The UV lamp must completely cover the entire area of the substrate coated with UV-curing gel to ensure that all the UV-curing gel is irradiated and solidified, in order to guarantee the quality of the wearable nail adhesion. This inevitably causes some UV light to shine on the non-nail areas of the upper surface of the finger, which can easily lead to sunburn in those areas and affect the appearance of the fingers.
[0003] The time required for UV-cured gel to solidify under UV light is affected by the light transmittance of the wearable nail material. Under the same conditions, the higher the light transmittance of the wearable nail material, the shorter the time required for UV-cured gel to solidify, and the less likely the fingers will tan. Therefore, existing wearable nail materials typically require high light transmittance. Before being applied to the nail, a decorative layer (usually an opaque coating with dark colors or embellishments) cannot be pre-made on the outer surface of the wearable nail layer; otherwise, it will interfere with UV-cured gel curing, and in severe cases, may prevent the gel from solidifying. The operator needs to temporarily create a decorative layer on the front of the already applied wearable nail substrate after fixing it to the nail to be manicured (e.g., applying decorations or coloring the front of the substrate). Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a photocurable wearable armor in which the decorative layer can be pre-made onto the front side of the substrate layer without affecting the photocurable gel from receiving irradiation.
[0005] To solve the above problems, this utility model provides a light-curing wearable nail, including a light-transmitting substrate layer, the back of which is provided for applying light-curing gel to adhere and fix to the nail to be manicured, a decorative layer is provided on the front of the substrate layer, and a reflective layer is provided between the substrate layer and the decorative layer. The front of the reflective layer extends forward and above the front of the nail to be manicured. The reflective layer reflects the curing light that shines in from the back at an angle to the rear onto the light-curing gel that has been applied to the back of the substrate layer.
[0006] Furthermore, the light transmittance of the substrate layer is greater than 50%.
[0007] Furthermore, the substrate layer is made of plastic and / or resin.
[0008] Furthermore, the front portion of the substrate layer and / or the front portion of the decorative layer also extend forward and above the nail to be manicured.
[0009] Furthermore, the photocurable gel is a UV adhesive.
[0010] Furthermore, the decorative layer includes a color coating and / or an adhesive layer containing microbeads and / or an attached decorative element.
[0011] Beneficial effects: The operator first takes a piece of light-cured wearable nail made using the manufacturing method of this utility model, applies light-curing gel to the back of the substrate layer of the light-cured wearable nail, and then attaches the back of the substrate layer to the upper surface of the nail to be manicured through the light-curing gel, with the front of the back of the reflective layer extending beyond the front and top of the nail to be manicured, leaving an irradiation position directly below, in front of, or diagonally below the front of the back of the reflective layer; the light-curing irradiation device is then used to irradiate the front of the back of the reflective layer through the irradiation position. The irradiated curing light first penetrates the light-transmitting substrate layer from bottom to top, is reflected by the back of the reflective layer, and then penetrates the light-transmitting substrate layer from top to bottom, irradiating the light-curing gel applied between the back of the substrate layer and the upper surface of the nail, causing the light-curing gel to solidify, and the light-cured wearable nail is thus adhered and fixed to the nail.
[0012] The decorative layer can be pre-made onto the front of the substrate layer, eliminating the need for a temporary decorative layer to be created on the front of the substrate layer after it has been glued and fixed to the nail, as in the prior art. Because the photocurable wearable nail system of this invention uses a photocuring irradiation device that shines light from the front of the back of the reflective layer, the curing light does not need to pass through the decorative layer located on the front of the substrate layer. The decorative layer does not affect the photocuring gel's ability to solidify under irradiation. Therefore, the substrate layer is unaffected by the decorative layer and can be firmly adhered to the nail. Furthermore, because the photocuring irradiation device shines light from the front of the back of the reflective layer, even after prolonged irradiation, only the fingertips or finger pads will tan, unlike the prior art which tanned the skin on the non-nail areas of the upper surface of the finger. Compared to the skin on the upper surface of the finger, the fingertips or finger pads are not easily seen in daily life, so even if they tan, the impact on the appearance of the fingers is minimal.

[0017] The present invention will be further described in detail below with reference to specific embodiments.
[0018] See Figure 1 and Figure 2 The photocurable wearable armor 1 includes a substrate layer 11, which is made of a high-transmittance plastic material such as acrylic (PMMA) (transmittance greater than 50%). In other embodiments, the substrate layer 11 can be replaced with a high-transmittance resin material. A decorative layer 12 is provided on the front side of the substrate layer 11. The decorative layer 12 can be a color coating, an adhesive layer containing microbeads, or an attached decoration. A reflective layer 13 is sandwiched between the substrate layer 11 and the decorative layer 12, and is capable of reflecting light incident from the back.
[0019] To produce the aforementioned multi-layered, light-cured wearable armor 1, a substrate layer 11 is first taken, and a reflective layer 13 with a matching curvature is placed on the front of the substrate layer 11, thus completing the reflective layer 13 forming step. Then, a decorative coating is applied to the front of the reflective layer 13 and allowed to solidify to form a decorative layer 12, thus completing the decorative layer 12 forming step. This completes the light-cured wearable armor 1. In this embodiment, the reflective layer 13 in the reflective layer 13 forming step is placed directly on the front of the substrate layer 11. Therefore, in the decorative layer 12 forming step, the edges of the decorative layer 12 and the substrate layer 11 need to be partially bonded. After the decorative layer 12 is formed, the two layers can together sandwich the reflective layer 13 located between them. In other embodiments, the reflective layer 13 forming step may not involve placing a single piece of reflective layer 13 on the front side of the substrate layer 11. Instead, a reflective coating may be applied to the front side of the substrate layer 11, and after the reflective coating solidifies to form the reflective layer 13, the reflective layer 13 is directly bonded to the front side of the substrate layer 11. Correspondingly, the decorative layer 12 in the decorative layer 12 forming step can be changed to be directly bonded to the front side of the reflective layer 13. Furthermore, in this embodiment, the reflective layer 13 forming step is performed first, followed by the decorative layer 12 forming step. In other embodiments, the decorative layer 12 forming step can be performed first, followed by the reflective layer 13 forming step. For example, a piece of reflective layer 13 can be taken first, and then a decorative coating can be applied to the front side of the reflective layer 13 and allowed to solidify to form the decorative layer 12, thus completing the decorative layer 12 forming step; then, the back side of the reflective layer 13 can be bonded to the front side of the substrate layer 11, thus completing the reflective layer 13 forming step. Furthermore, when performing the above-mentioned decorative layer 12 forming step, a protective coating (not shown in the figure) can be first applied to the front of the reflective layer 13, and then the decorative layer 12 can be formed on the front of the protective coating. At this time, although the decorative layer 12 and the reflective layer 13 are separated by the protective coating, the decorative layer 12 is still placed on the front of the reflective layer 13. When it is necessary to wear the light-cured wearable nail 1, take a piece of the prepared light-cured wearable nail 1, apply a light-curing gel such as UV glue 3 to the back of its base layer 11, and then let the back of the base layer 11 be attached to the upper surface of the nail 2 to be manicured through the UV glue 3, and make the front of the base layer 11, the front of the decorative layer 12 and the front of the reflective layer 13 extend beyond the front and top of the nail 2 to be manicured, leaving an irradiation position 14 below the front of the back of the reflective layer 13, as shown in Figure 1. The UV curing irradiation device 4 shines from the front of the back of the reflective layer 13 at an angle of 45° to the rear through the irradiation position 14. The UV curing light shining from the UV curing irradiation device 4 penetrates the light-transmitting substrate layer 11 from bottom to top, is reflected by the back of the reflective layer 13, and then penetrates the light-transmitting substrate layer 11 from top to bottom, irradiating the UV adhesive 3 that has been applied between the back of the substrate layer 11 and the upper surface of the nail 2. The UV curing irradiation device 4 maintains the irradiation for 60 seconds to ensure that the curing light can fully irradiate all the UV adhesive 3 and solidify it. The UV-cured wearable nail 1 is then pasted and fixed on the nail 2, thus completing the wearing operation of one UV-cured wearable nail 1.In other embodiments, the UV curing irradiation device 4 can be modified to irradiate from the back of the reflective layer 13 through an irradiation position of 0° to 90°. Correspondingly, the irradiation position 14 can be modified to be located directly below, directly in front of, or diagonally below the front of the back of the reflective layer 13, and the irradiation time can be adjusted to 30s to 150s depending on the type of photocurable gel.
[0020] The decorative layer 12 of the UV-cured wearable nail 1 can be pre-formed on the front of the substrate layer 11 before wearing, unlike the prior art where the decorative layer 12 is temporarily created on the front of the substrate layer 11 after it has been glued to the nail 2. Therefore, the wearing operation is simpler and more time-saving, and a wider variety of styles can be designed / made. The UV curing device 4 shines from the front of the back of the reflective layer 13, and the curing light does not need to pass through the decorative layer 12 located on the front of the substrate layer 11. The decorative layer 12 does not affect the UV adhesive 3 from receiving irradiation and solidifying. Therefore, the substrate layer 11 is not affected by the decorative layer 12 (transparency) and can be firmly attached to the nail 2. In addition, because the UV curing device 4 shines from the front of the back of the reflective layer 13, after long-term irradiation, only the fingertips or finger pads will be tanned, and the skin on the upper surface of the finger other than the nail 2 will not be tanned as in the prior art. Compared with the skin on the upper surface of the finger, the fingertips or finger pads are not easily seen in daily life, and even if they are tanned, the impact on the appearance of the fingers is small.
[0021] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
