Detailed ways

Hereinafter, an artificial nail according to an embodiment of the present invention will be described in detail with reference to the drawings.

It should be noted that the size of each component in the drawings may be inconsistent with the actual size, which needs to be considered with reference to the actual situation. In addition, the embodiments described below are merely examples for illustrating the present invention, and the present invention is not limited thereto, and modifications, changes, etc. made within the scope of the present invention are included in the present invention.

As shown in FIG. 1 , the side of the artificial nail 1 fixed to the human nail 4 during use may be called an inner surface, and the side opposite to the inner surface may be called an outer surface. Also, sometimes the end of the artificial nail 1 that is close to the root of the human finger (that is, the end close to the palm) is called the rear end, and the end far from the root of the human finger is called the front end. In addition, the direction of the artificial nail 1 that coincides with the longitudinal direction of the human finger during use may be referred to as the longitudinal direction, and the direction perpendicular to the longitudinal direction (that is, the width direction of the palm) may be referred to as the transverse direction.

artificial nails 1

As shown in FIGS. 1 and 2 , in one embodiment of the present invention, the artificial nail 1 is formed in a two-stage structure. Specifically, the artificial nail 1 includes a base part 2 and a shaping part 3 , and the Shore hardness of the base part 2 is smaller than that of the shaping part 3 . For example, the base part 2 is formed into a hard nail with a Shore hardness of 40HD or more and 60HD or less for sticking to the human nail 4, and the modeling part 3 is formed as a hard nail with a Shore hardness greater than 65HD for front-end modeling of the artificial nail 1. . The base part 2 and the molding part 3 can be prepared by manufacturing methods known in the art, for example, they can be formed by injection molding or molded.

As for the measurement of the Shore hardness of the base part 2 and the molding part 3, a measurement method known in the art can be used. Its working principle is: under the action of the test force, the indenter is vertically pressed into the surface of the sample. When the surface of the indenter is completely attached to the surface of the sample, the tip of the indenter has a certain protruding length relative to the plane of the indenter. The size of the elongation is used to characterize the size of the Shore hardness. In the present invention, for example, a D-type Shore durometer with an indenter head size of 0.1 mm in radius can be used to measure the hardness of the base part 2 and the molding part 3 respectively. In addition, the base part 2 and the modeling part 3 may be tested at different positions of the sample for multiple times, for example, 5 times, and an average value is taken.

When in use, the base 2 can be pasted on the human nail 4 first, and then the styling part 3 can be pressed or glued on the base 2 . Then brush the seal layer on the outer surfaces of the base part 2 and the modeling part 3, for example, transparent resin or the like can be brushed. Finally, place the artificial nail 1 that has been coated with the sealing layer under, for example, ultraviolet light, and cure it with a baking lamp, so as to fix the artificial nail 1 on the human nail 4 . But it is not limited thereto, and the usage steps can also be appropriately changed according to actual needs. For example, the joining of the base part 2 and the molding part 3 can be completed by the manufacturer before the product leaves the factory, or can be completed by the user after purchasing the product.

The artificial nail 1 has a plurality of base parts 2 of different sizes, shapes or types and a plurality of styling parts 3 of different sizes, shapes or types, so as to be able to meet different needs of users.

In addition, since the base 2 and the modeling part 3 are both hard nails, the outer surface of the base 2 can also be modeled before the sealing layer, such as pasting decorations, design patterns, painting, etc. Trim, sand, attach decorations, design patterns, paint and more. In this way, not only different nail bed and nail head shapes can be freely matched, but also the nail design of the nail bed part and the nail head nail design can be freely matched.
