Description

  The present invention relates to a stratum corneum removal device mainly for human skin, and more particularly to a skin stratum corneum removal device that can efficiently remove a keratinized portion of skin generated in wrinkles and the like.

  Conventionally, in order to remove the stratum corneum generated in human heels, elbows, etc., it is known to scrape off the stratum corneum using pumice stone cut into a size and shape suitable for use. However, with this method, the fine space of the pumice clogged with shavings, etc., and the performance deteriorates, and the removal of the shavings is not easy. It is not preferable. As a means for solving such problems, the stratum corneum has a structure in which a cutting blade is annularly arranged and attached to a main body having a grip portion, and the cutting blade is pressed against the stratum corneum and rubbed to scrape off the stratum corneum. A layer removal tool has been proposed in Japanese Patent Application Laid-Open No. H10-228707.

  In addition, the bottom plate of the casing is used as a guide when removing the stratum corneum to be treated, and the cutting edge of the cutting blade is protruded from the bottom surface of the casing and pressed against the skin surface. Patent Document 2 proposes a keratin remover that can be easily collected.

  In addition, Patent Document 3 discloses that the skin is cleaned and conditioned by scraping the skin surface layer (keratin layer) using a base material in which fine protrusion elements are densely arranged on the skin surface layer. It has been.

  However, in the prior art, for example, in the stratum corneum removal tool known from Patent Document 1, the cutting edge is pressed against the skin at a substantially right angle, and the surface layer of the stratum corneum is scraped while maintaining this state. In other words, the stratum corneum surface is squeezed by the blade, so that the efficiency is low, and there is a risk of damaging the skin unless the pressing force is determined. Moreover, since it contacts a wide surface at once, there is a problem that skill is required to scrape the keratinized portion by pressing against a curved surface during use. Naturally, since the blade edge is used in an upright position, the sharpness is likely to deteriorate, and the blade edge cannot be sharpened and regenerated.

  Further, in the stratum corneum removal tool known from Patent Document 2, the stratum corneum is cut by projecting the cutting edge portion of the cutting blade from the bottom plate surface with the bottom plate surface of the casing as a guide, and the bottom plate surface of the cutting edge portion. Since it also has a function of adjusting the exposure amount from the (guide), it is recognized that it is more effective than that according to Patent Document 1. However, since this stratum corneum removal tool has a structure in which a cutting blade is incorporated in the casing, in order to properly treat the cutting blade pressed against the target stratum corneum removal portion, The casing is in the way and cannot be seen. Therefore, there is a problem that the cutting blade is applied to the treatment target portion with a register, and there is a risk of damaging healthy skin when it is removed from a necessary portion, and considerable skill is required for free use.

  The technique disclosed in Patent Document 3 is a base material provided with fine elements (projections) having regularly arranged edge portions, and the skin surface is removed by rubbing the skin surface. It is effective for disassembling / removing comedones arising from dead cells on the surface layer or skin pores covered with makeup, etc., but is suitable for scraping off a thick and hard stratum corneum. Absent. Even if scaled up in shape, it is difficult to secure a cutting edge in the structure, which is not practical due to increased costs.

  The present invention has been made to solve the problems in the prior art, and is a skin stratum corneum removal device that can remove a stratum corneum freely and safely without requiring a special technique with a simple structure. It is intended to provide.

In order to achieve the above object, a device for removing a stratum corneum from a skin according to the present invention comprises:
A plurality of cutting holes are drilled at intervals that do not interfere with each other on a substrate formed of a hard material and having a suitable width, and the inner peripheral edge of each cutting hole forms a cutting edge. (1st device).

  In the above device, the substrate may include a grinding layer having fine abrasive grains attached to the surface (second device).

  In the present invention, since the inner peripheral edge of the hole provided in the substrate formed of a hard material is used as a blade, by applying the substrate to the stratum corneum that is raised on the skin surface and pulling it, Since the entire circumference of the inner edge of the plurality of holes functions as a cutting blade, the stratum corneum is scraped by one of the hole edges and is not greatly cut at once, so it can be scraped off without deep cutting . Therefore, if the substrate is applied to the stratum corneum according to the shape of the skin surface at the target site, the substrate surface immediately slides as a guide surface, so that the hole inner edge corresponding to the moving direction is cut. It functions as a cutting edge and can cut the stratum corneum.

  Thus, according to the present invention, since the inner edge of the hole provided in the flat plate is used as the cutting edge, directionality is not required for the cutting edge, so it can be applied to any part of the limb to be treated. Correspondingly, by pressing and sliding the substrate, the stratum corneum can be gradually scraped without deep cutting, and there is an advantage that handling is easy. In addition, since the inner edge of the hole is a cutting edge, it is safe without damaging the skin during normal handling, and it has an effect that it can be provided at low cost because it has a simple structure.

  Further, by adopting the configuration of the second device, it is possible to cut the peripheral surface of the cutting portion with the abrasive grains attached to the substrate surface simultaneously with the cutting and smooth the surface roughness, and to efficiently treat the surface. There is an effect.

  Next, a specific embodiment of the skin stratum corneum removal device according to the present invention will be described with reference to the drawings.

  FIG. 1 is an overall perspective view showing the skin stratum corneum removing device of the present embodiment. 2 is an enlarged sectional view taken along line AA in FIG. 1, FIG. 3 is a partially enlarged perspective view of another embodiment, and FIG. 4 is an enlarged sectional view of the main part of FIG. ing.

  The skin stratum corneum removal device 1 (hereinafter simply referred to as “the stratum corneum removal device 1”) of this embodiment is formed into an elongated shape with a heat-treated metal plate having a required thickness, and has a plurality of holes. And the inner peripheral edge 5 of the cutting hole 4 provided in the substrate 2 is formed into an edge shape, and the edge portion (inner peripheral edge) is formed. Part 5) is designed to be a cutting blade. The handle 3 is covered with a handle made of plastic or the like so that it can be easily grasped by hand during use.

  The substrate 2 is a steel plate having a thickness of about 1 mm, and the width 3 is narrower than the minimum width of a human (adult) limb (leg or arm), and the handle 3a is integrated with an appropriate length. The tip 2a (opposite to the handle 3a) is rounded on both sides in the width direction.

  When the cutting hole 4 provided in the substrate 2 is pressed against the stratum corneum of the skin to be treated, the hole size (specifically, the stratum corneum a can protrude into the cutting hole 4). Is formed in a round hole having a diameter of 5 mm or more. The cutting holes 4 are provided in a plurality of rows in a staggered arrangement, for example, at a required interval in the longitudinal direction. In addition, about the space | interval of the cutting hole 4, it is set as the dimension which does not interfere mutually, and it is preferable to set the board | substrate 2 in the state which can maintain rigidity.

  The substrate 2 is heat treated so that the inner peripheral edge 5 of the cutting hole 4 formed of stainless steel and functioning as a cutting edge is formed of stainless steel. Therefore, it is preferable that it is formed of stainless steel (for example, martensitic stainless steel SUS420J2, SUS410, etc.) that is easily quenched. If heat treatment is performed so that the sharpness of the cutting edge can be maintained, the cutting function can be maintained for a long time.

  The substrate 2 may be formed of a steel plate other than stainless steel, ceramic, thermosetting resin, or the like as a constituent material. However, when forming with a non-metallic material, it is desirable to make it the thickness required in order to maintain an intensity | strength and to ensure the edge (blade edge part) formed in a cutting hole part.

  When the stratum corneum removing device 1 of the present embodiment configured as described above is used, when the surface of the substrate 2 is pressed against the surface of the stratum corneum a to be treated and slid back and forth, the surface layer of the stratum corneum a A part of a ′ is pushed into the cutting hole 4 provided in the substrate 2 as shown by a two-dot chain line in FIG. When the substrate 2 slides in this state, a part of the surface layer a ′ of the stratum corneum a that protrudes into the cutting hole 4 is scraped off with the inner peripheral edge 5 of the cutting hole 4 serving as a cutting edge. At this time, the stratum corneum is cut by the inner peripheral edge 5 (edge portion) facing the traveling direction of the cutting hole 4. Therefore, since a small part is cut by the one operation, it is not a deep cut. The shavings are discharged from the cutting hole 4 toward the upper surface of the substrate 2. Since the substrate 2 is provided with the plurality of cutting holes 4 as described above, when removing the stratum corneum on a wide surface, the stratum corneum is simultaneously applied to the plurality of cutting holes 4 by pressing the substrate 2. Layer a will be shaved. Thereafter, if this operation is repeated and the stratum corneum a portion to be removed is removed gradually little by little, the treatment can be carried out without difficulty. In addition, since the stratum corneum removing instrument 1 has a narrow width dimension and a large number of inner peripheral edge portions 5 of the cutting holes 4 provided as cutting edges, the user himself / herself visually recognizes the treatment site while stratum corneum is visible. Since a can be excised, it can be treated efficiently and safely.

  Next, FIG. 3 shows a stratum corneum removing instrument according to another embodiment, and the basic configuration thereof is the same as that of the above embodiment. The stratum corneum removal instrument 1A of this embodiment is formed of stainless steel (or heat-treatable steel plate) capable of heat-treating the substrate 2 as in the above-described embodiment, and other than the formation portion of the cutting hole 4 provided in the substrate 2. Abrasive grains 7 (for example, diamond abrasive grains, hard ceramic powder grains, alumina abrasive grains (alundum), silicon carbide abrasive grains (carborundum), etc.) are attached to the surface (upper and lower surfaces, the same applies hereinafter). A grinding layer 6 is provided. Note that components that are the same as or similar to those of the above-described embodiment are denoted by the same reference numerals as those of the above-described embodiment, and detailed description thereof is omitted.

  As a means for forming the abrasive layer 6 by adhering the abrasive grains 7 to the surface of the substrate 2, it is preferable to adhere and fix, for example, by electrodeposition or vapor deposition. In addition to this, an adhesive may be optionally used. Further, if the grinding layer 6 is provided close to the periphery of the cutting hole 4, the sharpness of the edge portion (blade edge portion) formed on the inner peripheral edge portion 5 of the cutting hole 4 is maintained for a long time. Can be effective.

  The mode of use by the stratum corneum removing instrument 1A of the embodiment configured in this way can be used in the same manner as in the above-described embodiment, and the surface layer of the stratum corneum a against which the tool is pressed is a portion where the ground layer 6 contacts And the stratum corneum surface layer portion a ′ protruding into the cutting hole 4 is cut by the cutting edge portion formed on the inner peripheral edge portion 5 of the cutting hole 4, and the stratum corneum layer a It can be removed. In particular, the cutting edge 4 has a cutting edge 4 with a peripheral edge 5 by attaching abrasive grains 7 of the grinding layer 6 provided on the surface of the substrate 2 to the periphery of the cutting hole 4 as described above. Since the stratum corneum a is scraped ahead by the grains 7 and assists the scraping with the cutting edge, the effect of the removal treatment can be further enhanced.

  FIG. 5 is an overall perspective view of a stratum corneum removal device according to another embodiment. The stratum corneum removal device 1B of this embodiment is provided with a file surface 10 at a portion corresponding to the handle portion of the substrate 2. Note that components that are the same as or similar to those of the above-described embodiment are denoted by the same reference numerals as those of the above-described embodiment, and detailed description thereof is omitted.

  In this stratum corneum removing device 1B, the substrate 2 and the support portion 8 (pattern portion) provided with the file surface 10 are integrally formed, and the width of the support portion 8 is slightly wider than the width of the substrate 2 portion. (However, it is not limited to this.) The file surface 10 formed on one side of the support portion 8 is formed by regularly projecting innumerable protrusions 11 at an appropriate pitch, and the protrusions 11 are preferably formed in a conical shape. . Such a protrusion 11 is preferably formed by forging pressure on the support portion 8 formed together with the substrate 2, for example. Further, on the surface of the substrate 2 and the support portion 8 having the file surface 10, a grinding layer 6 is provided, which is formed by attaching the same abrasive grains 7 as in the above embodiment. By doing so, the protrusion 11 on the file surface 10 has the abrasive grains 7 attached to the surface, thereby enhancing the function as a file.

  The stratum corneum removing device 1B configured as described above is stratum corneum by the inner peripheral edge portion 5 in the cutting hole 4 by being applied and rubbed against the surface of the stratum corneum to be treated in the same manner as in the above embodiment. The surface layer of the layer is scraped off and scraped in a wide range by the abrasive grains 7 of the grinding layer 6 on the surface of the substrate 2. Further, if the file surface 10 is used, a wide range of stratum corneum can be cut by the infinite number of protrusions 11. At this time, since the abrasive grains 7 are attached to the projections 11 of the file surface 10, the surface layer of the stratum corneum can be quickly scraped off. Therefore, the stratum corneum can be scraped off at 2 parts of the substrate provided with the cutting holes 4 and the scraped off at the file surface 10 can be properly used depending on the situation. Note that if the support portion 8 has a filed surface 10 with a projection 11 on one side and a grinding layer 6 made of abrasive grains 7 is formed on the opposite surface, a cutting hole is formed in the portion of the grinding layer 6. This is convenient because the surface of the stratum corneum that has been scraped off by the surface 4 or the filed surface 10 can be finished smoothly.

  FIG. 6 is a perspective view of a stratum corneum removal instrument according to still another embodiment. In this embodiment, the basic configuration is the same as that described above, and the structure of the substrate 2 is different. Accordingly, structural elements that are the same as or similar to those of the above-described embodiment are given the same reference numerals as those of the above-described embodiment, and detailed descriptions thereof are omitted.

  The stratum corneum removal device 1C of this embodiment is formed by bending a substrate 2c with a metal plate (stainless steel or other steel plate) with a suitable radial dimension in the same manner as described above, and the outer surface thereof is the same as in the previous embodiment. A large number of cutting holes 4 are drilled. In addition, a ground layer 6 made of abrasive grains 7 is provided on the surface (upper and lower surfaces or curved outer peripheral surface) of the substrate 2c thus configured, as in the above embodiment.

  When the stratum corneum removing device 1C configured as described above mainly deletes the stratum corneum using the curved outer surface side, the stratum corneum removing device 1C can be partially abutted against the stratum corneum and treated. Therefore, local intensive excision can be performed, and it is possible to work without bringing the instrument into contact with the peripheral portion of the portion to be removed, and it is easy to visually recognize the periphery thereof, so that treatment can be performed with peace of mind.

  Further, if the inner circumferential surface of the substrate 2c is used, it can be used so as to remove the stratum corneum at the projecting portion such as the elbow, and the cutting edge portion of the cutting hole 4 is surrounded by the projecting portion. Since it is provided at the peripheral edge 5, it can be moved and scraped in a free direction without regard to directionality, which is effective.

  In the description of the embodiment provided with the grip handle described above, the description of the grip portion of the substrate 2 (2c) is omitted, but the grip portion (handle portion 3) is formed with a separately formed handle (for example, made of plastic). ) Can be externally fitted to the handle 3a of the substrate 2 so that it can be easily gripped. Further, if necessary, the pattern may be omitted and the extended portion of the substrate 2 (2c) may be used as a pattern as it is. Moreover, about the board | substrate 2, it can also be arbitrarily made to form in a short dimension as needed, and to make it easy to handle. Furthermore, it can be set as the structure where the shape of the board | substrate was bent in the width direction as needed. It goes without saying that such a configuration also belongs to the technical category of the present invention.
