Description

Nail Beauty Equipment {NAIL FILE}

The present invention relates to a nail beauty instrument, and more particularly to a nail beauty instruments that can be polished to the desired shape by grinding the end of the nail.

Nail files are called nail files, which can be used to cut nails or toenails into desired shapes and trim them into beautiful shapes.

1A-1C show the structure of a conventional representative nail file. Conventional nail piles first use a rigid body such as metal or plastic to make a flat bar plate 18 integrally with the handle 10, and then thereon a cushion layer such as a double-sided tape 16 and a sponge thereon. After attaching (14) in sequence, the polishing layers 12 and 13 are formed on the cushion layer 14 in a bonded structure by bonding.

By the way, in the case of the conventional nail file, an industrial paper sandpaper having fine abrasive grains 12 uniformly attached on the paper layer 13 having strong tensile strength was used as the polishing layer. In general, the paper sandpaper is bonded to the abrasive particles 12 evenly distributed on the paper layer 13, the surface state of the abrasive layer is always in a smooth pattern without a texture.

Therefore, since the roughness of the surface is obtained by the roughness or size of the abrasive grains 12 itself, it is difficult to obtain a surface state with strong abrasive force. In particular, the continuous use of the nail file, the nail powder fills the gap between the abrasive particles 12, there is a problem that the surface roughness is gradually weakened. The distance between the abrasive grains 12 is dense and the hand using impact force It is also not easy to shake off the saw powder. It may be considered to remove the nail powder using water, but water is not appropriate because it causes a problem of weakening the bonding force of the double tape 16 which bonds the bar plate 18 and the cushion layer 14 to each other. .

The object of the present invention is to provide a navy with excellent polishing performance and durability because the abrasive layer is formed in an irregular shape only on the portion where the ink is printed by using a silk screen printing technique.

In order to achieve the above object,

A flat plate substrate, an ink layer printed in a predetermined shape by silkscreen printing on one or both surfaces of the substrate, and an abrasive grain layer for nail polishing applied on the ink layer and strongly bonded by the ink layer and a strong adhesive agent. Provided is a nail file for nail polishing, characterized in that provided.

The surface of the nail polisher is characterized in that the first portion is coated with the abrasive grain layer and the abrasive grain layer is not applied, characterized in that formed on the concave and convex surface alternately arranged the second portion is exposed.

The substrate includes a polishing unit substrate to which the abrasive grain layer is bonded, and a handle integrally formed with the polishing unit substrate.

In addition, the substrate is characterized in that the rigid body (rigid body) is injected into the shape of a flat rod using a polymer material as a raw material.

The strong adhesive is a mixture of the strong bonding material stock solution and dilution in a predetermined ratio, the mixing ratio is preferably 1: 2 ~ 1: 5 characterized in that. A representative example of the strong bonding material is an epoxy resin.

The strong adhesive is added by spraying on the abrasive grain layer and the substrate, or by submerging the substrate to which the abrasive grain layer is adhered to the strong adhesive for a predetermined time.

The predetermined shape may be a shape in which the ink layer is printed and the original substrate surface is alternately mixed. Examples of this may vary, such as a net, comb-shaped, wavy.

Other features and advantages of the present invention will become more apparent with reference to the following detailed description and accompanying drawings that illustrate the features of various embodiments of the invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

Figure 2a to 2c shows the structure of the nail file according to an embodiment of the present invention. 3A and 3B are enlarged views corresponding to No. 32 of FIG. 2A, the former exemplifying a pattern of ink 36 printed by the silkscreen technique on the surface of the substrate 20b, the latter being the ink 36 A portion of the surface of the nail file is shown by applying abrasive particles 34 to the printed pattern.

Referring to Figures 2a and 2b, respectively, showing a plan view and a side view of the nail file, the nail file is a bar-shaped flat substrate formed in one piece with the handle 20a, that is, the emery machine It is composed of a board (emery board) 20b, and the polishing layer 30 thinly bonded to one or both surfaces of the substrate (20b). The abrasive layer 30 is composed of ink 36 applied on the substrate 20b and abrasive particles 34 applied on the ink 36, and the abrasive particles 34 are strongly bonded to each other by a strong adhesive. In addition, it is also strongly bonded to the substrate 20b.

The polishing layer 30 partially covers the surface of the substrate 20b but not all of them. That is, the surface of the nail file alternately includes a portion 34 to which the polishing layer 30 is applied and a portion 38 where the polishing layer 30 is not applied so that the substrate 20b covered with a thin adhesive is exposed to the outside. Is placed. As a result, the nail pile has a concave-convex shape by the substrate layer 20b and the polishing layer 30. Of course, the abrasive grains 30 themselves also form a finer uneven surface.

The pattern formed by the polishing layer 34 on the substrate 20b may vary. This is because the pattern of the polishing layer 34 depends on the printed pattern of the ink 36 printed on the substrate 20b. In addition, since the ink 36 on the substrate 20b is printed using a silk screen printing technique, the printed pattern can be variously modified. Although the figure shows a net shape as one example of the printed pattern, it is a matter of course that it can be modified into various various patterns. As long as the surface forms an uneven | corrugated shape by the board | substrate layer 20b and the grinding | polishing layer 30, any pattern is possible. For example, a comb-tooth pattern, a wave pattern, or a sawtooth pattern is a typical modified example, and a pattern in which these are mixed is also possible.

Next, a method of manufacturing a nap file according to an embodiment of the present invention will be described.

First, the substrate 20b is prepared. The substrate 20b is manufactured in the shape of a flat bar. Preferably, the handle 20a is further formed on one side of the substrate 20b. Since a force is applied to the substrate 20b and the handle 20a during nail beauty, it is necessary to make the substrate and the handle as a solid material that can withstand the force, and it is preferable to form both as integral as possible. The material that can be used as the material of the substrate 20b is not limited as long as it has the above rigidity. For example, a metal body, an acrylonitrile-butadiene-styrene (ABS) resin, a polypropylene resin, and a polyethylene resin Polymer compounds such as the like and the like can be used. For example, when using it as a material of an ABS resin roll substrate, the board | substrate 20b and the handle 20a can be integrally manufactured using the molding method.

After the substrate 20b is prepared, the silkscreen ink 36 is printed in a predetermined pattern by applying a silkscreen printing method on one plane or both planes of the substrate 20b.

To this end, a silkscreen printing film that can print a desired pattern is prepared. The pattern formed by the printed ink 36 is determined by the pattern of the printing film. Here, as described above, the portion 34 to which the polishing layer 30 is applied and the portion 38 where the polishing layer 30 is not applied and the substrate 20b covered with the adhesive thinly exposed as it is are exposed to the outside alternately. As long as it can be arranged, the type of the pattern is irrespective. However, hereinafter, the pattern formed by the printed ink 36 as illustrated in the drawings for convenience of description A case of mesh shape will be described as an example. In order to deform the printed pattern of the ink 36, the pattern of the printing film may be replaced with the desired one, so that the pattern may be easily deformed.

The printed film is made into a desired pattern, and then the injection molding and the printed film are mounted on a jig (not shown) for silk screen printing. Here, in order to make the adhesion strength between the ink and the substrate to the best state, it is necessary to select a suitable ink according to the material of the substrate 20b. When the substrate 20b is made of ABS resin, it is preferable to use silk screen ink for ABS resin. Silk screen printing apparatus or more detailed printing method can be easily carried out by those skilled in the printing field will be omitted here.

After the silkscreen printing is finished, before the printed ink 36 dries, the abrasive particles for hairdressing beauty (cosmetic sand or emery) 34 are evenly spread over the substrate 20b. The scattered abrasive particles 34 adhere only to the portion where the ink 36 is buried by the viscosity of the ink, and do not adhere to the portion where the ink 36 is not buried. The substrate 20b is turned upside down to shake off the abrasive particles 34 that did not adhere to the ink 36.

After the abrasive particles 34 are attached on the ink 36, the ink may be allowed to dry naturally before proceeding to the next process. However, in order to help dry the ink and reduce the manufacturing time, a predetermined temperature environment, for example, 50 degrees Celsius or more may be used. Heating may be performed in a temperature environment of about 60 degrees.

The ink 36 adheres to the abrasive particles 34 as it does not itself provide strong adhesion. The lifting force is not so strong. Since the nail file is exerted by the friction with the nail, the abrasive particles 34 should be strongly adhered to the substrate 20b. Therefore, a process of adding an adhesive (not shown) to the polishing layer 30 to strongly adhere the abrasive particles 34 to the substrate 20b is performed.

The adhesive may use a general bonding material used for industrial purposes. Preferably epoxy resin is used that provides strong adhesion.

The method of adding the adhesive to the abrasive particles 34 can vary.

First is a method of spraying the adhesive using a sprayer (not shown). When epoxy resin is used as the adhesive, the epoxy resin solution is difficult to spray because of its high viscosity. Therefore, for example, it is desirable to lower the viscosity so that the spraying operation is easy by appropriately mixing with the diluent. Too much diluent can make spraying easier, but weaker, and in the opposite case stronger, but harder to spray. In view of such a point, it is preferable that the mixing ratio between the epoxy resin stock solution and the diluent is appropriately selected within the range of about 1: 2 to 1: 5. Examples of diluents that can be used for diluting epoxy resins are various. For example, one or more low molecular weight, liquid selected from one or more low molecular weight, liquid, epoxy-functional compounds, or aliphatic alchol-alkylene oxide adducts. Etc. may be exemplified, but the type of diluent is not limited thereto.

As another method, the abrasive particles 34 are mixed in a mixed solution of the epoxy resin stock solution and diluent solution. A method of dipping the coated substrate 20b may be used.

When the adhesive is added in this manner, the adhesive penetrates between the abrasive particles 34 to strongly bond the abrasive particles 34. In addition, the abrasive particles 34 are integrally bonded to the substrate 20b.

After adding the adhesive, the adhesive is allowed to dry naturally, and finally the desired nail file is completed. Instead of going through such a natural drying process, it may be further subjected to a forced drying process for enhancing the adhesive strength of the polishing layer 30 to the substrate 20b by heating at a predetermined temperature, for example, 70 degrees Celsius or less.

Although specific embodiments of the present invention have been described so far, it is understood that various changes can be made without departing from the spirit of the present invention. For example, by varying the size of the abrasive particles, it is possible to make various kinds of nail piles having different surface roughness. In addition, it is possible to produce a nail file of various colors by modifying the color of the ink.

Furthermore, the present invention has the advantage that the abrasive particles can be variously modified in the patterns applied to the substrate of the nail file using the silk screen printing method. If the nail file is used as an advertising promotional material, it is also possible to print the company logo on the substrate.

It is also possible to form a so-called nail buffer layer on one side of the substrate which forms a polishing layer and the other side to polish the nail.

In addition, an abrasive layer is applied to the substrate in an uneven shape and the abrasive particles are used as a strong adhesive. Since it adheres to the substrate, even when nail powder gets stuck in the polishing layer, the nail powder can be easily removed and reused when put in lukewarm hot water and shaken, so the durability of the polishing property is excellent. The durability of the polishing layer is excellent.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art various modifications and variations of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.
