Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sharpener for nails and stratum corneum, and more specifically to the nails as well as the stratum corneum formed on elbows, knees, heels, etc. The present invention relates to a sharpening tool for nails and stratum corneum, which is capable of sharpening greasiness in a smooth shape or removing pain from a lumpy feeling.

[0002]

2. Description of the Related Art Conventionally known sharpeners for nails and stratum corneum include metal files obtained by etching a metal plate, foamed urethane with nylon flocking, and hard urethane formed on a porous surface to form a pumice stone. It is known that the crushed stone, the metal plate or the like coated with an abrasive such as sand, and the pumice stone.

[0003]

However, in the above-mentioned conventional sharpeners for nails and stratum corneum, the contact condition of the nails, stratum corneum, etc. to the care portion is flat, and the entire blade contact surface is elastic. Since it is a rigid surface with no sharpness, it is inconvenient to use, and further, scraps scraped off by the blade of the sharpening tool are caught and accumulated in the vicinity of the recess on the surface of the sharpening tool, which causes problems such as clogging of the file surface. there were.

In order to solve the above problems, the present invention solves the above problems by providing an applicator in which a through hole is formed in a thin metal plate and an edge is formed around each through hole. It was done.

[0005]

For this reason, in the present invention, a large number of through holes are formed in a thin metal plate, and a edging blade is formed at the surface side edge portion of the through hole to surround the metal thin plate. It is a sharpening tool for nails and stratum corneum, which is characterized by enclosing with a gripping frame.

[0006]

According to the present invention, a edging blade is formed at the edging portion of the through hole, and the nails and scraps of the stratum corneum scraped off by the edging blade pass through the through hole and fall below the thin metal plate. , No dust will remain on the upper surface of the thin metal plate.

Further, since the metal thin plate itself is surrounded by the gripping frame in a flexible state to some extent, the sharpening tool can be easily held stably and the sharpening operation can be easily performed.

Further, since the metal thin plate itself is formed by electroforming nickel or nickel alloy, precision processing becomes possible, and the edge of the edging blade is sharp, and the product has excellent durability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments of the drawings. In the present invention, the metal thin plate 1 is used as a material, and nickel or nickel alloy electroformed products are suitable as the material.

A large number of through holes 3 of any shape such as a long hole, a circle, a rectangle, a square, a triangle, etc. are formed in the thin metal plate 1, and the edge of the through hole 3 has a edging blade. 2 is formed. Usually, the thickness of the metal thin plate 1 is about 30 to 200 microns, but especially 70
Approximately 80 microns can ensure appropriate flexibility and is easy to use.

Further, in the thin metal plate 1, each edging blade 2
The surfaces of the adjacent space portions can be formed in the recessed portion 4 that is lower than the surrounding edging blade surface, but of course it is also possible to form a smooth surface portion without forming the recessed portion.

If the concave portion 4 is formed, when the tip of the toe and the stratum corneum are rubbed while being pressed against the edging blade 2 on the surface of the metal thin plate 1, the friction resistance of the contact portion is increased and the metal thin plate It does not slip on the surface and gives a good feeling in use.

The overall shape of the plane of this metal thin plate 1 is
The shape can be an appropriate shape such as a circle, an ellipse, a rectangle, a rectangle, or a triangle, and the periphery thereof is surrounded by the gripping frame 5 so as to have the respective shapes.

Since the grip frame 5 is formed of a synthetic resin or wooden frame having a good feel, the whole frame is easy to hold and easy to use.

First, a metal thin plate 1 of nickel electroformed product as shown in the longitudinal sectional view of FIG. 3 is manufactured by a known electroforming manufacturing method.

Here, since the thin metal plate 1 of nickel electroformed product is formed so that the blade surface layer gradually increases in thickness by a plating-like manufacturing method, the thickness dimension and size are extremely precise. , The shape can be secured.

Further, the hardness of the metal thin plate 1 of the present invention is preferably Vickers hardness of about 300 to 600,
In particular, 400 to 500 is most suitable, and as a result, it is necessary and sufficient hardness is secured as a sharpening tool for nails and stratum corneum.

Further, the sharpening tool shown in FIGS. 6 to 8 is one in which the gripping frame 5 is integrated with the saucer 6, and a part of the lower surface of the saucer has a take-out hole for taking out the polishing residue of the nail or the stratum corneum. 7
Has been drilled. By doing so, all the scraps that have been sharpened are stored in the tray 6 through the through holes 3, and the scraps collected in the tray are discarded through the take-out hole 7.

Further, in the state where the metal thin plate 1 is attached to the gripping frame 5, the surface side of the edging blade 2 can be formed into a curved surface like a concave lens. There is an effect that the tip of the stratum corneum easily hits the curved surface of the thin metal plate. Of course, it is also possible to form the thin metal plate 1 into a plate-shaped flat surface if necessary.

The edging blade 2 of the thin metal plate 1 has a rough finishing 2a and a fine finishing 2
It is also possible to combine b and b in a single sheet (see FIG. 13), and it is also possible to form the edging blade 2 so that the roughness of the mesh is gradually made finer.

Various forming patterns of the edging blade 2 are possible. As shown in FIG. 1, a large number of elongated holes are arranged in parallel, and the arranging dies are oriented vertically and horizontally. It is also possible to change the shape of the edging blade, or to arrange the whole in an irregular manner, and the forming pitch of the edging blade can be freely set.

Since the present invention relates to the above-mentioned construction, the gripping frame is used as a palm to apply the toe, the stratum corneum, the octopus and the bean portion, etc. to the edging blade forming surface of the thin metal plate, which is unnecessary for the edging blade. It removes unnecessary parts, smooths the care part, and removes lumpy and stiff parts to relieve pain.

The sharpened dust scraped off by the edging blade 2 is
It is dropped from the front surface to the back surface of the thin metal plate through the through holes 3, and it is possible to reliably prevent clogging around the edging blade.

[0024]

As described above, according to the present invention, the nails and stratum corneum can be easily and surely finished to be smooth, and the octopus and the legumes can be relieved of pain. , The sharpening operation is easy, and the sharpening scraps are concentrated on the back side of the metal thin plate without scattering to the surroundings, which has an excellent effect that the sharpening scraps can be easily and cleanly discarded. .

Further, the present invention has a structure that does not adhere an abrasive or the like and is durable because it does not rust easily. In addition, it has a feature that it is easy to use because the polishing surface does not easily become clogged.
