BACKGROUND

1. Field of the Invention

The present invention relates to a foot exfoliator with a high-gloss nail polisher and an electric foot exfoliation kit, and more particularly, to a foot exfoliator with a high-gloss nail polisher and an electric foot exfoliation kit coupled to the foot exfoliator that are nail and foot care tools made of a hard material such as glass and that remove dead skin cells without damaging the living skin so as to make soles of feet smooth.

2. Discussion of Related Art

In general, nail polishers and foot exfoliators have certain patterns formed at certain intervals on a glass surface to polish the nails and skin to remove dead skin cells therefrom and make them glossy or have protrusions formed in a hexagonal honeycomb shape to trim the nails.

The nail polisher and foot exfoliator are made as follows. Chromium (Cr) and metal with excellent chemical resistance are formed on a hard substrate such as a glass substrate, a photosensitive film such as a photoresist (PR) film or a dry film photoresist (DFR) film is coated thereon to form a protrusion pattern on the glass, a mask having a protrusion pattern is placed on the PR (or DFR) film to form protruding portions of the nail polisher, the mask is exposed to ultraviolet (UV) light so that protrusion images are photosensitized on the photosensitive film, the glass substrate irradiated with UV light is immersed in a developer so that the protrusion pattern is formed on the PR (or DFR) film, and then Cr and glass formed under the PR are sequentially etched so that protrusions are formed on the glass.

The hexagonal arrangement of protrusions has a problem in that, when polishing is performed in horizontal and vertical directions, since intervals between non-protruding portions are large, scratching may occur on the nail and thus the nail may not become glossy, or serious damage may be caused to the skin when removing dead skin cells from a sole of a foot.

Hereinafter, a process of manufacturing the nail polisher and foot exfoliator will be described prior to describing various embodiments of the present invention.

First, chromium (Cr) and metal with excellent chemical resistance are formed on a hard substrate such as a glass substrate, and then a photosensitive film such as a photoresist (PR) film or a dry film photoresist (DFR) film is coated thereon to form a protrusion pattern on the glass. Next, a mask having a protrusion pattern is placed on the PR (or DFR) film to form protruding portions of the nail polisher, and the mask is exposed to ultraviolet (UV) light so that protrusion images are photosensitized on the photosensitive film. Next, the glass substrate irradiated with UV light is immersed in a developer so that the protrusion pattern is formed on the PR (or DFR) film. Then, Cr and glass formed under the PR are sequentially etched so that protrusions are formed on the glass.

Hereinafter, embodiments of a foot exfoliator with a high-gloss nail polisher, which is manufactured using the above manufacturing process, and an electric foot exfoliation kit for the foot exfoliator will be described.

<First Embodiment> Foot Exfoliator with High-Gloss Nail Polisher

The foot exfoliating part 10 to which the vertical stripe protrusions 122 of the protrusion column 120 are coupled will be described in more detail with reference to FIG. 2. A plurality of protrusion 110 regions each formed of one or more protrusions selected from the protrusions 110 having the circular shape 111, the elliptical shape 112, and the rhombic shape 113 (see FIG. 4) and a plurality of protrusion columns 120 consisting of the vertical stripe protrusions 122 formed as if dividing the protrusion 110 regions are arranged on a certain area of the plate.

In the foot exfoliating part 10 having the above structure, the circular, elliptical, or rhombic protrusions in the protrusion 110 regions scratch off dead skin cells, and the protrusion columns 120 consisting of the vertical stripe protrusions 122 remove dead skin cells as if cutting off the same and smooth the skin surface.

Here, the vertical stripe protrusions 122 are formed so that width a of each of the protrusions is in a range of 50 to 1,000 μm, interval b between the protrusions is in a range of 50 to 1,000 μm, and height h of each of the protrusions is in a range of 5 to 1,000 μm.

The nail polishing part 20 of the foot exfoliator with the high-gloss nail polisher according to the present invention is configured by arranging a plurality of vertical stripe protrusions 211, each of which stands upright, or arranging a plurality of inclined stripe protrusions 212, each of which stands obliquely, in order to perform nail polishing in regions of an area of the plate excluding the foot exfoliating part 10.

The nail polishing part 20 of the present invention is divided into a dense region and a loose region, and stripe protrusions 210 may be arranged at different intervals b for each region.

In the nail polishing part 20 having the above structure, the stripe protrusions (vertical/inclined) arranged to be divided into the two different regions are configured to trim a main part of the nail in the loose region and polish the nail and make the nail glossy in the dense region.

Here, the protrusions 210 in the dense region are arranged at intervals b′ in a range of 50 to 500 μm, and the protrusions 210 in the loose region are arranged at intervals b″ in a range of 500 to 1,000 μm.
