Description

  The present invention relates to a keratin remover, and more particularly, to a keratin remover that scrapes hardened keratin such as an octopus on the sole of a foot safely and efficiently.

  Conventionally, the exfoliation has been removed by grinding with a grinding tool having a file-like or abrasive surface, or by cutting with a sharp tool such as a razor or a cutter. In addition, it requires a strong force, and with a sharp blade, the amount to be excised is not stable and it is deeply cut or bloodshed.

For this reason, for example, a plurality of cutting holes 4 are formed at intervals that do not interfere with each other on the substrate 2 that is formed of a hard material and formed into a flat plate having an appropriate width. The peripheral edge 5 forms a cutting edge. A ground layer 6 made of abrasive grains 7 is attached to the surface of the substrate 2. In use, the substrate 2 is pressed against the surface of the target portion and the stratum corneum is scraped off by the blade edge portion formed at the inner peripheral edge portion 5 of the cutting hole 4 (see Patent Document 1), or a part thereof is cut off by a plane. A main body 4 having a spherical crown-shaped grip portion 3 and a blade portion 6 detachably attached to a hole 5 formed by recessing a portion cut out by a plane of the main body 4. The blade portion 6 includes a blade support portion 7 that is screwed into the hole 5 of the main body 4, and annular blades 8 and 9 whose base portions are embedded in the blade support portion 7. The annular blades 8 and 9 are cylindrical blades (inner blade 8 and outer blade 9) having different diameters extending from the blade support portion 7 at the same predetermined height L1, and concentrically with the blade support portion 7. Arranged. A cutting surface is formed by a plane connecting the cutting edges of the blades 8 and 9. The inner blade 8 and the outer blade 9 are configured such that shavings are accumulated in the space S2 defined by the gap S1 between the blades 8 and 9 and the inner blade 8 (see Patent Document 2). Alternatively, the exfoliating tool 1 includes a main body 3 and a grip portion 5 attached to the main body 3 integrally. The outer periphery of the main body 3 includes a first curved portion 7, a second curved portion 9, a third curved portion 11, and a fourth curved portion 13. The curvature of the first curve portion 7 is larger than the curvature of the second curve portion 9, and the curvature of the first curve portion 7 is larger than the curvature of the third curve portion 11. The edge part along the 1st curve part 7, the 2nd curve part 9, and the 3rd curve part 11 is formed with a knurled blade part 15 in which irregularities are alternately arranged (see Patent Document 3). Is disclosed.

  However, although the thing of patent document 1 forms the some cutting hole 4 in the flat board | substrate which has arrange | positioned the abrasive grain 7 on the surface, the cutting hole 4 is a flat thing and cutting is slippery. It is not stable and has low efficiency, and it takes a long time to remove keratin, and the one described in Patent Document 2 has cylindrical blades (inner blade 8 and outer blade 9) with different diameters. Although it is arrange | positioned concentrically at the blade support part 7, each cylindrical blade is flat, and cutting is not slippery and stable, Furthermore, the thing of patent document 3 is spoon-shaped. Although the blade portion is formed on the side surface, if it is a sharp blade portion that is the same as that cut with a razor or a cutter, the foot may be damaged.

  In view of the above problems, as a result of keen study, the exfoliating tool has a blade portion that bulges in an annular manner and gradually in the direction of the blade edge under one end of the main body, and the blade edge is formed into an annular blade having a sharp cross section, A vertical stripe line is engraved on the inner surface or outer surface or inner / outer surface of the annular blade, or a wave shape is formed on the blade edge by forming a vertical stripe uneven portion, and a plurality of blade portions are provided close to each other. In addition, the plurality of blade portions are arranged without a gap between each of the diameters of the main body in the width direction.

  The blade portion of the exfoliating device of the present invention is swelled below the main body having a length, the blade tip is formed into an annular blade having an acute cross section, and the annular blade is provided with a vertical stripe line or a vertical stripe uneven portion, The blade edge is formed in a wave shape, and the annular blade can be easily brought into contact with the keratin such as the octopus of the sole by grasping the base end of the handle portion, and the blade edge of the ring blade is formed in a wave shape. As a result, it is possible to prevent injuries without the sides of the blade being slid, and it is possible to scrape the keratin sufficiently efficiently even at 50 to 60 ° without making the blade edge very sharp. Is high.
