For example, the three-dimensional pattern sheet 10 may have a length of 1 cm to 3 cm. According to an embodiment of the present invention, the three-dimensional pattern sheet 10 may have a length of 1.5 cm to 2.5 cm.

The width of the three-dimensional pattern sheet 10 generally means a distance in a short direction from one object, and since a person's fingernail is composed of a curved surface and the fingernail width is different for each person, it is not limited thereto. For example, the three-dimensional pattern sheet 10 may have a width of 0.1 cm to 2.5 cm. According to an embodiment of the present invention, the three-dimensional pattern sheet 10 may have a width of 0.2 cm to 2 cm. This can be arbitrarily adjusted in consideration of the length extended by the curved surface.

The shape of the three-dimensional pattern sheet 10 can be manufactured in various ways according to the shape of the nail. In general, the nails are different for each person and the nails of one person are also different for each finger, so the present invention is not limited thereto. However, self-forming should be possible. If it is produced in a specific shape, for example, a three-dimensional pattern sheet produced in a rectangular shape or a round shape only at the end is highly unlikely to be self-forming. Additionally, you can add volume in the shape of a registration line. For example, it may be manufactured in a form having a volume in the center.

As shown in FIG. 10A , each object may be placed with a gap of 1 mm to 10 mm therebetween.

By using the three-dimensional pattern sheet 10 according to an embodiment of the present invention, the length of the nail can be extended and the product can be easily attached and detached, thereby minimizing damage to the nail and extending naturally along the curve of the nail. Therefore, you can get nails with a natural form.

In addition, according to an embodiment of the present invention, the three-dimensional pattern sheet 10 of the present invention is the three-dimensional pattern sheet 10 of the present invention for the operations of nail trimming, bonding, foam paper insertion, extension material application, and non-curing performed in the previous nail length extension method. It can be replaced by pasting.

Accordingly, the difficulties and inconveniences in the various steps of the length extension procedure are solved, and the procedure can be performed without using various harmful substances such as bonds and primers used in the procedure. That is, by using the product of the present invention, a novice technician or a self-nail consumer without skilled skills can perform a length extension procedure.

In addition, it is manufactured as a finished product in the form of a sticker, so it is safe from harmful substances. For example, when chemicals such as UV ink come into contact with nails or flesh, they may act detrimentally to the human body.

Therefore, the three-dimensional pattern sheet 10 in the present invention has an optimal interlayer configuration, interlayer thickness, softness, material, and type, and it is possible to extend the length of the nail by being manufactured under these conditions.

11 is a photograph showing a three-dimensional pattern sheet according to an embodiment of the present invention.

Referring to FIG. 11 , a process of comparing the three-dimensional pattern sheet 10 to the nail according to an embodiment of the present invention can be confirmed. Through the above process, it is possible to find a three-dimensional pattern sheet 10 having an appropriate size for the nail to which the three-dimensional pattern sheet 10 is to be attached.

12 and 13 are diagrams illustrating design elements of a three-dimensional pattern sheet according to an embodiment of the present invention.

12 and 13 , it can be seen that the design element of the three-dimensional pattern sheet according to an embodiment of the present invention can be formed in various ways without limitation. As disclosed, if there is a picture to be included, it can be printed and displayed on the three-dimensional pattern sheet 10 . The design element may be formed in the first direction and/or the second direction of the three-dimensional pattern layer 100 .

14 and 15 are diagrams illustrating examples of a sculptural design of a three-dimensional pattern layer according to an embodiment of the present invention.

14 and 15, the three-dimensional pattern layer 20 according to an embodiment of the present invention is not simply a shape having a curve, but a engraving design such as a processed metal such as diamond, or various designs such as a lace or a logo. It can also be confirmed that they are applicable. The design of the three-dimensional pattern layer 20 is not limited because it can be changed according to the shape of the mold frame changed according to the intention of the manufacturer.

As described above, in the present invention, the three-dimensional pattern sheet can be manufactured by being composed of the metal pattern layer and the sheet layer. According to an embodiment of the present invention, it is possible to easily perform the treatment by anyone by greatly reducing the various treatment steps required for the length extension treatment in a sticker method, and it is possible to block harmful substances used in the treatment in terms of structure, as well as to prevent damage to the nails when applied. It appears as a natural shape following the shape. In addition, it is easy to introduce desired decorations and colors on the three-dimensional pattern sheet.

Those skilled in the art from the above description will be able to see that various changes and modifications can be made without departing from the technical spirit of the present invention. Accordingly, the technical scope of the present invention is not limited to the contents described in the detailed description of the specification and should be defined by the claims.
