Description

Technical Field

[0001] The invention relates to the technical field of nail stickers, and in particular to a nail sticker, a nail sticker kit, and a preparation method thereof. Background Art

[0002] As one of the ways for humans to express their pursuit of physical beauty, the beauty industry is developing rapidly and is also showing a trend of segmentation. In particular, after the 20th century, as the market expanded rapidly, the beauty industry began to gain popularity among the public. Recently, in the beauty industry, nail art has developed rapidly as an important element of the art of body expression regardless of age or gender.

[0003] Initially, manicure, as a field of beauty art, refers to a method of beautifying the human body. The length, shape or color of the nails reflects the cultural changes and values ​​of the times.

[0004] In manicure, people use artificial nail stickers in the shape of fingernails or toenails. In the past, nail stickers in the shape of fingernails or toenails were made into curved shapes and provided to consumers. Such nail stickers are provided to consumers in a hard and solidified state as injection molded products. However, the shapes of fingernails or toenails (especially curvature) of each person are different from each other, so it is difficult to tightly adhere the curved nail stickers to the fingernails or toenails of consumers.

[0005] Recently, as a method for solving this problem, nail stickers including ultraviolet curing materials have attracted much attention. Specifically, the nail stickers including ultraviolet curing materials have a flat shape below, and the user (consumer) changes the shape of the nail sticker to fit his or her fingernails or toenails, and then irradiates ultraviolet rays to cure the nail sticker. As a result, the fingernails or toenails of the user can be tightly bonded to the nail sticker, thereby improving the adhesiveness of the nail sticker. This type of nail sticker is also called a gel nail sticker.

[0006] On the one hand, the thickness of the gel nail sticker may be slightly thicker due to various reasons. For example, when the gel nail sticker is long and has a shape that extends further from the end of the fingernail or toenail in addition to the part that overlaps with the fingernail or toenail, the thickness may become thicker in order to maintain its shape. In addition, even if it is not necessarily the above reasons, the thickness of the gel nail sticker may be slightly thicker due to cosmetic reasons. In this way, when the thickness of the gel nail sticker is thick, even if the user applies force to the gel nail sticker to change the shape to fit his or her fingernail or toenail, the gel nail sticker is easy to return to its original shape. Therefore, it is difficult to wear the gel nail sticker to fit the shape of one's fingernail or toenail.

[0007] Therefore, a nail sticker that can be more effectively worn on a fingernail or toe nail is needed. Summary of the invention

[0008] The present invention is made to solve the above-mentioned problems, and one object is to provide a nail sticker that can be easily shaped by a user according to the shape of his or her nails.
