[0001] NAIL ACCESSORIES AND MANUFACTURING METHOD [0002]

The present invention relates to a nail accessory, and more particularly, to a nail accessory and a method of manufacturing the nail accessory.

Generally, women use a variety of ornaments such as rings, necklaces, bracelets, and earrings, and these ladies' ornaments are developed and popularized according to the fashion and trend of the times.

In recent years, there has been a growing interest in nail decoration as a result of the nail art culture among women, such as painting a pattern on a nail with a nail, attaching a decal or attaching an artificial nail.

However, the process of painting or attaching dyed or artificial nails to give a decorative effect to the nails is not suitable as an ordinary jewelery because it is cumbersome and it is time to remove the painting with acetone or to remove the artificial nails with adhesive liquid It took a long time, and there were problems such as bruising the nails.

In order to solve the above-mentioned problem, an ornament in which a decorative cover like a nail is formed on a nail when worn on a finger has been developed. For example, Korean Utility Model Registration No. 20-163144 "Health nail ring" Korean Patent Registration No. 20-209756 entitled " Nail Entanglement ", Korean Patent Laid-Open No. 10-2005-15096 " Nail Cover Easy to Attach to Nail Section " Registered New Design Registration No. 20-369884 entitled "Nail Accessory" has been filed and registered.

However, since the conventional nail ornaments described above are all manufactured by pressing the steel plate, the patterns formed on the decorative part are all flat, and the three-dimensional beauty can not be variously formed on the decorative part, which is the life of the nail ornaments, There is a disadvantage in that there is a limitation in the upgrading of the product.

In addition, the nail ornaments made of thin steel plate are easily deformed by external impact and the original shape is deformed. Therefore, it is often modified or discarded for circular restoration, so that the service life of the product is short and most of the wear parts are formed into a ring shape. Because it is not easy, detachment is not easy, and there is a disadvantage that it is not good fit because of interference.

In order to adapt the elasticity according to the thickness of the fingers, for example, as disclosed in Japanese Patent Application Laid-Open No. 2005-15096 or Utility Model Registration No. 202756, a wear part is formed in a ring shape, and a nodule part is formed in the lower part of the ring. However, They are superimposed on each other so as to be formed into a perfect circle when viewed from the side so as to surround and press the entire circumference of the finger,

In addition, as shown in the Utility Model Registration No. 199174 and the Utility Model Registration No. 369884, the wearing portion is formed into a spiral shape or the wearing portion is formed in a circular shape as in the Utility Model Registration No. 163144, but a slight gap is provided in the lower portion. It is disadvantageous in that it is not easily detachable and the feeling of fit is not good.

Domestic Utility Model Registration No. 20-163144 "Health Nail Ring" Domestic Utility Model Registration No. 20-199174 "Nail Accessory" Korean Utility Model Registration No. 20-202756 entitled "Nail Accessory" Korean Patent Laid-Open No. 10-2005-15096 " Nail Cover Easy to Attach to Nail Section " Korean Utility Model Registration No. 20-369884 "Nail Accessory"

In the present invention, a non-slip coating layer 34 may be formed on the inner side of the holder 30.

The present invention also relates to a method for manufacturing an aluminum alloy body, comprising the steps of injecting a molten alloy of aluminum and zinc into a mold to integrally cast a body (B) comprising a nail lid portion (10) and a decorative portion (20) B, a polished polishing step of polish-polishing the surface of the barrel-polished main body B, and a polishing step of polishing the polished polished main body B with gold, silver, or copper And a holder 30a manufactured by manufacturing an arc-shaped holder 30a by press-processing an iron plate into a coupling protrusion 22 formed on both sides of the plated body B, And then assembling the holder portion 30 to manufacture a finished product of the nail entanglement A of the present invention.

In addition, the present invention may further include the step of forming a non-slip coating layer 34 inside the holder 30.

The nail ornaments of the present invention are manufactured by casting a nail lid portion and a decorative portion with aluminum or zinc alloy to form a variety of three-dimensional patterns on the decorative portion, thereby improving aesthetics as a nail ornaments and matching with various tastes of consumers It is possible to upgrade the product.

In addition, the decorative part and the nail cover which are molded by aluminum and zinc alloy are hard because they are not easily deformed by external impact, and the lower open holder part composed of the circular arc holder is easily resiliently adapted to the thickness of the fingers. The nail cover is securely fastened because the finger is not sick or injured because the finger is easily released through the opening formed in the lower portion of the holder portion even if the nail lid is hung or severely impacted. When the nail-sliding coating layer is formed on the inner surface of the holder portion, It will not easily flow down or turn sideways while wearing your fingers.

In addition, when the body of the nail ornaments is molded by casting with aluminum or zinc alloy, the material is light and hard, the luster is good in the polishing process, and casting molding is advantageous in that defective products can be easily selected compared with press molding.
