The basic article 120 is manufactured by foaming the foamed resin which is the raw material 110 (step S110). Here, the foamed resin may include polyurethane and methylene diphenyl diisocyanate (MDI). Such foamed resin is intended to safely remove the dead skin of the body, the raw material of the foamed resin is not necessarily limited thereto. That is, the foamed resin may use a synthetic resin having similar characteristics (for example, elastic force).

The base product 120 includes a first hemisphere 121 and a second hemisphere 122. In one embodiment, the first hemisphere 121 and the second hemisphere 122 may be manufactured, respectively. If each is manufactured, the base product 120 may be manufactured by heat-sealing the first hemisphere 121 and the second hemisphere 122. In one embodiment, the height and diameter of each of the first hemisphere 121 and the second hemisphere 122 may be different. For example, FIG. 2 shows that the height is assumed to be about twice the diameter. In this case, the shape of the base product 120 may correspond to an elliptical shape that is convenient for the user to hold by hand. The base product 120 corresponding to the elliptical phase can obtain the effect of pressure on the sole of the foot.

The base product 120 is dried after surface washing (step S120). Surface cleaning is to remove foreign substances generated in the manufacturing process of the foundation product (120). In one embodiment, in Figure 2, surface cleaning may use the washing water sprayed from the washing nozzle (210). For example, the wash water may include thinners. Drying may be carried out at high or low temperatures depending on the foamed resin.

The first workpiece 130 is produced by applying the pressure-sensitive adhesive 311 to the outer surface of the dried base product 120 (step S130). In one embodiment, the adhesive 311 may be sprayed from the adhesive nozzle 310 may be sprayed on the outer surface of the base product 120. For example, the pressure-sensitive adhesive 311 has a phenol resin which is a thermosetting resin as a main component. Thermosetting resins are characterized by very high water resistance, heat resistance and chemical resistance.

The secondary workpiece 140 is produced by adhering the abrasive stone 320 to the outer surface of the primary workpiece 130 to which the pressure-sensitive adhesive 311 is applied (step S140). In one embodiment, the abrasive stone 320 is an abrasive in the form of powder particles, and uses the abrasive stone 320 corresponding to the intended use of the abrasive tool. For example, black-based silicon carbide (SiC) or white (transparent) -based aluminum oxide (Al ₂ O ₃ ) is used.

In one embodiment, the size of the abrasive stone 320 may correspond to the diameter of 0.1mm to 0.4mm, the density of the abrasive stone 320 adhered to the outer surface of the primary workpiece 130 has an area of 1cm 2 50 to 70 particles (grains) can stick. More preferably, the density of the abrasive stone 320 may be attached to about 60 particles. If the size of the abrasive stone 320 is too small, it may be difficult to remove the dead skin, if too large may cause a wound on the dead skin removal portion.

In one embodiment, the abrasive stone 320 has a Crohs beryl (Crysoberyl), aluminite (Corundum, Corundum), Alexandrite (Mohs hardness) corresponding to 8 to 9 (Al ₂ SO ₄ (OH) .7H ₂ O], spinel, topaz. Such abrasive stone 320 can be easily obtained while the strength is sufficient to remove dead skin cells can lower the cost of the product.

In one embodiment, the abrasive stone 320 may include various additives. For example, charcoal powder may be further adhered to the outer surface of the primary workpiece 130. The ground powder may have air purification, electromagnetic wave blocking, far infrared radiation, and humidity control. As another example, glitter may be further adhered to the outer surface of the first workpiece 130. Glittering reflected light can produce a variety of colors to enhance the appearance and aesthetics of the tool.

The third workpiece 150 is produced by drying the second workpiece 140 at high temperature (step S150). The drying temperature may be adjusted according to the type of adhesive 311. The high temperature drying process may harden the pressure-sensitive adhesive 311 in a gel state so that the abrasive stone 320, charcoal powder and / or decorative member may be firmly fixed.

The final product 160 is produced by forming a protective coating layer on the outer surface of the third workpiece 150 (step S160). In one embodiment, the coating liquid 411 forming the protective coating layer is sprayed from the coating nozzle 410 is applied to the outer surface of the third workpiece 150. The protective coating layer may prevent the abrasive stone 320, the charcoal powder and / or the decorative member from being separated from the final product 160, and prevent the skin from being damaged by the abrasive stone 320. For example, the coating liquid 411 may be double coated using the adhesive 311. Even when the types of the coating liquid 411 and the adhesive 311 are different, when the coating liquid 411 which serves as an adhesive is used, the adhesive 311 is used as the first adhesive and the coating liquid 411 is defined as the second adhesive.

The final product 160 is antimicrobial treatment with an inorganic metal antibacterial agent containing antibacterial metal ions (Ag +, Zn ₂ +, Cu ₂ +, etc.) (step S170). Inorganic metal antimicrobial agents can prevent bacteria from penetrating into the human body in the process of removing dead skin with an abrasive tool. In addition, the inorganic metal antimicrobial agent may have higher stability, sustainability, and thermal stability to the body than other antimicrobial agents. In one embodiment, it may include antimicrobial metal ions (Ag +, Zn ₂ +, Cu ₂ +, etc.), these antimicrobial metal ions may have higher antimicrobial activity and safety.

On the other hand, keratin that occurs in the body is different from person to person and may vary from place to place. For example, keratin occurring on the heel and keratin occurring on the big toe, keratin occurring on the elbow may be different from each other. The user may have a plurality of exfoliating abrasives having different surface roughness, which makes the user inconvenient to store and use the plurality of exfoliating abrasives.

The disclosed technology may be divided into at least two portions of one exfoliating abrasive and may be manufactured to have different surface roughnesses for each of the divided portions.

In another embodiment, the second workpiece 730 may adhere to abrasive stones 820 having different sizes, densities, and colors. For example, in FIG. 9, a relatively small abrasive stone 821 may be attached to the upper body 741, and a relatively large abrasive stone 823 may be attached to the lower body 743. In another embodiment, the abrasive stone 820 adhered to the upper body 741 and the lower body 743 may be manufactured with one abrasive tool having different roughness. For example, when the upper body 741 adheres silicon carbide (SiC) and the lower body 743 adheres aluminum oxide (Al ₂ O ₃ ), the upper body is black and the lower part is white. have. Here, the size of the small abrasive stone 821 may be 0.1 mm to 0.2 mm in diameter, the size of the intermediate abrasive stone 822 may be 0.2 mm to 0.3 mm, the size of the large abrasive stone 823 is 0.3 mm to 0.4 mm.

The third workpiece is produced by drying the second workpiece 730 at a high temperature (step S615).

The attachment part, which is the lower surface of the upper body 741, is ground and processed (step S616). Grinding and processing can remove foreign substances present in the attachment portion and even the lower surface of the attachment portion. The upper body 741 and the lower body 743 may be hermetically welded by removing the foreign matter and making the attachment surface even.

In Figure 6, the manufacturing process of the lower body 743 by the "S621" to "S626" step is the same as the manufacturing process of the upper body 741.
