The soft part includes a face, a hand, etc., which are not in contact with other objects, a leg or a chest covered with clothes, And a foot which comes into contact with the hard surface of the shoe for a long time in a walking or standing state to harden some of the skin to form a stratum corneum.

Particularly, in the case of the foot, the stratum corneum becomes thicker over time, and even in the severe case, the stratum corneum sometimes cracks, causing pain, and bacteria and the like may infiltrate into the cracks.

A widely used method for removing such keratin is a keratinizer. Most exfoliators are made up of a bar-shaped handle and a grinding wheel at the end of the handle, which grasp the handle and scrub the crust of the foot using a polishing pad.

Korean Utility Model Registration No. 20-0244728 discloses a foot exfoliation port used for removing keratin which is generated on the heel of the foot by athlete's foot or drying. Such a technique is formed in such a structure that the polishing piece can be attached and detached from the main body, so that when the removing function of the keratin is lowered, only the polishing piece can be replaced and replaced with convenience.

Korean Patent No. 10-1361212 discloses a foot exfoliation remover which can easily remove keratin occurring at the back of the foot. Since this technique is made of sand, it has a certain weight and it can remove the dead skin of the foot by only rubbing the foot in the standing posture on the floor of the bathroom without bending the body.

Referring to FIGS. 1 and 2, a base product 110 is manufactured by foam molding a raw material 10 (step S101). In one embodiment, the raw material 10 corresponds to a foaming resin, and the foaming resin may include polyurethane and methylene diphenyl diisocyanate (MDI). The foaming resin is intended to safely remove the keratin of the body, and the raw material 10 is not necessarily limited to the foaming resin. That is, the raw material 10 may be a synthetic resin having properties (for example, elasticity) similar to that of the foamed resin.

The base product 110 may include at least two shapes that form the final product 140. That is, the base product 110 may include a first hemisphere 111 and a second hemisphere 112. The first hemispheres 111 and the second hemispheres 112 may be formed and thermally fused to form the base article 110. In one embodiment, in FIG. 2, the first hemisphere 111 and the second hemisphere 112 may be formed to have different heights and diameters, respectively. For example, the base product 110 may be embodied in an elliptical shape having a height about twice the diameter for the convenience of the user to hold by hand. The base product 110 corresponding to the elliptical shape can obtain the effect of shaking the sole.

The base product 110 is dried after the outer surface has been cleaned (step S102). Surface cleaning may be performed to remove foreign matter generated during the fabrication of the base product 110. In one embodiment, in Fig. 3, the surface cleaning may be performed through the wash water injected from the cleaning nozzle 20. For example, the wash water may include a thinner. The drying may be carried out at a high temperature or a low temperature depending on the foaming resin.

The first workpiece 120 is manufactured by applying a thermosetting resin 31 to the outer surface of the dried basic article 110 (step S103). In one embodiment, in Fig. 4, the thermosetting resin 31 may be ejected from the resin nozzle 30 and ejected onto the outer surface of the base product 110. [ For example, the thermosetting resin 31 may be a phenolic resin as a main component. The thermosetting resin is characterized by high water resistance, heat resistance and chemical resistance.

In one embodiment, the first primary workpiece 120 may be further adhered to at least one of the dye member and the decorative member upon application of the thermosetting resin (31) to the outer surface of the dried base product (110). For example, the first workpiece 120 may be coated with a dye material so as to have various patterns (or patterns) when the thermosetting resin 31 is applied, so that the appearance of the first workpiece 120 can be improved. For example, when the thermosetting resin 31 is applied to the first workpiece 120, the decorative member may be adhered to the first workpiece 120 to enhance the appearance of the first workpiece 120. Here, the dye member and the decorative member are not limited to being coated or adhered when the thermosetting resin 31 is applied.

In one embodiment, the primary workpiece 120 may be further adhered to the outer surface with charcoal powder. The charcoal powder can bring about an air purifying function, an electromagnetic wave shielding effect, a far-infrared radiation effect and a humidity control effect.

The second workpiece 130 is manufactured by heating the outer surface of the first workpiece 120 coated with the thermosetting resin 31 and then attaching the grinding stone 50 (step S104). 5, when the thermosetting resin 31 applied to the first workpiece 120 is melted (that is, the hardness is lowered) by the heating member 40, the second workpiece 130 is heated Can be adhered. In one embodiment, the grinding stone 50 is an abrasive in the form of powder particles, which is embodied as 0.1 mm to 0.5 mm in diameter, and may vary depending on the intended use of the abrasive article. For example, the grinding stone 50 may be implemented with a black series silicon carbide (SiC) or a white (transparent) series aluminum oxide (Al2O3). The grinding stone 50 may be adhered to 50 to 70 particles (grains) per 1 cm 2 of the outer surface of the primary workpiece 120. If the size of the grinding stone 50 is too small, the user can not smoothly remove the exfoliation of the body. If the size of the grinding stone 50 is too large, it may cause scratches on the exfoliation area of the body.

In one embodiment, the grinding stone 50 is made of corundum (Corundum) containing aluminum oxide (Al2O3) corresponding to 8 to 9 Mohs hardness, chrysoberyl ), Aluminite [Al2SO4 (OH) 7H2O], silicon carbide (SiC), spinel and topaz.

The second workpiece 130 is subjected to the heating process of the thermally-crystallizable resin 31 so that the first and second hemispheres 111 and 112 are formed in at least two shapes (i.e., the first and second hemispheres 111 and 112) The grinding stones can be made by sticking. The first and second grindstones may have different characteristics and the characteristics may be classified according to at least one of size, kind, hardness, toughness, grain shape, grain size and surface roughness. .

The secondary workpiece 130 may be made by adhering the coated grinding stone 50 to the outer surface of the heated primary workpiece 120. The coated grinding stone 50 may be previously coated and adhered to the secondary workpiece 130 so that it is more closely adhered to the thermosetting resin 31 so that a separate coding process is omitted before the final product 140 is manufactured . The coating liquid can prevent the skin from being damaged by the grinding stone (50). In one embodiment, the secondary workpiece 130 is heated by heating to cause a portion of the abrasive stone 50 to be sputtered on the outer surface of the primary workpiece 120 when the primary workpiece 120 is lower than the hardness prior to heating Sputtering). That is, the grinding stone 50 may be sputtered so as to be partially contained in the thermosetting resin 31 applied to the outer surface of the first workpiece 120 and not to fall off from the second workpiece 130.

The final product 140 is manufactured by drying the second workpiece 130 at a high temperature (step S105). The drying temperature may vary depending on the kind of the thermosetting resin 31. [ 6, in the high-temperature drying process, the thermosetting resin 31 whose hardness has been lowered is cured so that the grinding stone 50 can be firmly fixed.

In one embodiment, the final product 140 may be antimicrobially treated with an inorganic metal antimicrobial agent comprising an antimicrobial metal ion (Ag +, Zn2 +, Cu2 +, etc.). Inorganic metal antimicrobial agents can prevent bacteria from penetrating into the body in the course of removing horny substances with a polishing tool.
