Description

Keratin removing plate having micro-cutters and keratin removing device employed therewith}

The present invention relates to an exfoliator, and more particularly, to an exfoliator that can easily exfoliate with a small force by changing the shape of a plurality of micro cutters.

Conventional removal mechanism (Mechanism) for exfoliation of the skin of the hands and feet can be largely divided into four categories. There are exfoliators that use a variety of chemicals such as salicylic acid to grind the hard keratin formed on the sole to a powder, attach it with a razor, or dissolve skin keratin. .

The applicant of the present invention has registered a patent document (Republic of Korea Patent Registration No. 10-1184144) as the most recent related patent technology among the above four prior methods.

The patent document relates to an exfoliation plate in which a number of micro cutters, which are elements for removing exfoliation from an outer surface of an exfoliation plate made of thin steel material, are arranged.

In the micro cutter, a protruding plate having a circular or polygonal plane of a predetermined size is protruded to a height of 0.5 m or less. A through hole is formed between the flat protrusion plate and the outer surface along the outer periphery of the flat protrusion plate so that keratin can pass to the inner surface. A connecting portion connecting the outer surface and the flat protrusion plate between the through holes is formed on both sides with a width smaller than the outer size of the flat protrusion plate. It is characterized in that an acute cutting edge is formed on the outer periphery of the flat protruding plate so that keratin can be cut in both directions excluding the connecting portion.

Since the exfoliating plate is integrally formed with the exfoliating device, the exfoliating blade cannot be used to change the front-rear direction (rear side closer to the handle and forward side handle and far side) with respect to the direction of use. Because the user habitually exfoliates only in the forward (for example, the direction of pushing the handle) or in the reverse (in the direction of pulling the handle), only one of the cutting edges of the front and back cutting edges is worn, and the other side is not worn. Although the cutting edge remains, there is a problem in that it is impossible to use a cutting blade that is not worn due to a habit, so that the exfoliator must be discarded.

In addition, since a plurality of micro cutters are formed on one plane (all micro cutters are of the same height), that is, formed on a straight flat plate, all micro cutters correspond to the skin, and thus, when they are in contact with the skin and apply force, respectively ( Since all of the microcutters dig into the keratin skin, there is a problem that it takes a lot of effort to remove the keratin. In addition, there is a problem in that the microcutter cannot contact the concave portion and cannot exfoliate in a body part narrower than the area of the exfoliator (for example, the concave portion of the sole).

In addition, since the flat protruding plate is formed in a circular shape and the cutting edge is made of a curvature of a circle smaller than a semicircle, respectively, along the outer edge of the flat protruding plate, the side portion is short and the exfoliator is inclined obliquely from the longitudinal direction when using the exfoliator. There was a discomfort that was more difficult to use because it could not give the acute effect of the blade due to moving.

Republic of Korea Registered Patent Publication No. 10-1184144 (2012.09.18.)

In the following description of the present invention, when it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, detailed descriptions thereof will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or practice. Therefore, the definition should be made based on the contents throughout this specification.

1 is an exploded perspective view of an exfoliator 1 according to an embodiment of the present invention. 1, the exfoliator 1 protects the exfoliation plate 100, the body frame 200 on which the exfoliation plate 100 is assembled, and the exfoliation plate 100 from external impact, etc. It covers the cover so as to include a cover 300 coupled to the body frame 200.

First, as a preferred embodiment of the present invention, the configuration and operation of the exfoliation plate 100 will be described.

As shown in Figures 1 to 5, the exfoliation plate (hereinafter abbreviated as "exfoliation plate") formed with a micro cutter according to the present invention (100), a plurality of micro cutters 20 are arranged a cutter plate ( 10), it is composed of a support frame (30) to support by coupling the cutter plate (10).

The cutter plate 10 is planar as shown in FIG. 12, or preferably is formed as a curved surface having a predetermined curvature as shown in FIG. 2 or 10. In addition, the cutter plate 10 is a symmetrical structure that can be disassembled and assembled to the support frame 30 by changing the assembly direction from the longitudinal direction of the exfoliator back and forth.

Here, the cutter plate 10 is preferably made of stainless steel, and the cross-section is made of a convex curved surface in which the central portion is more convex than the left and right sides. Such a curved surface can concentrate the force while contacting the contact area that meets the same surface as the user's skin surface with a narrow area, and also can reduce dead skin by reducing cutting resistance.

4 to 5, the micro cutter 20 is a flat plate-shaped protrusion plate 21 from the surface of the cutter plate 10 is spaced apart from the upper surface of the cutter plate 10 through the connecting portion 22 (Fig. 3 reference top) is formed to protrude. Accordingly, the cutter plate 10 is formed with keratin passage holes 23 and 24 along the outer periphery of the protruding plate 21, and cutting edges 25 and 26 are formed to be inclined at a predetermined angle on the edge of the outer peripheral surface of the protruding plate 21. do.

The protruding plate 21 has a generally flat oval shape and protrudes from the surface of the cutter plate 10 to a height of 0.1 mm to 0.5 mm. The protrusion height of the protruding plate 21 is a height that determines the thickness of cut off keratin from the skin and does not exceed a maximum of 0.5 mm for user safety.

On the other hand, the connecting portion 22 is for connecting the protruding plate 21 to the cutter plate 10, as shown in Figures 4 and 5, preferably both sides of the protruding plate 21 facing each other, that is, two places Respectively. The connecting portion 22 is formed in a smaller width than the protruding plate 21 in the center of the outer circumferential surface of the protruding plate 21 in consideration of the size of the keratin passing holes 23 and 24 and the cutting edges 25 and 26.

The keratin passage holes 23 and 24 are formed in an arc shape on both sides with the connection portion 22 as the center, so that the keratin peeled off by the corresponding cutting edges 25 and 26 passes.

Hereinafter, referring to FIGS. 4 and 5, the first cutting edge 25 and the first keratin passing hole 23 formed on the left side of the connecting portion 22 and the second cutting edge 26 formed on the right side, and The second keratin passage hole 24 will be referred to as each.

Here, the cutting edges (25,26) is to cut the keratin, it is formed to be inclined while forming an acute angle with respect to the flat surface of the protruding plate (21). At this time, the cutting edges 25 and 26 are formed along the entire outer circumferential surface of the protruding plate 21 except where the connecting portion 22 is located, so the protruding plate 21 is first on both sides based on the connecting portion 22. , 2 cutting blades (25,26) are formed symmetrical.

That is, the keratin peeled off by the first cutting edge 25 is discharged through the first keratin passing hole 23, and the keratin peeled off by the second cutting edge 26 is discharged through the second keratin passing hole 24. do.

The first and second cutting edges 25 and 26 of the micro cutter 20 of the present invention having such a configuration are structures for obtaining an acute angle effect described later, which will be described in detail with reference to FIG. 4.

The first and second cutting edges 25 and 26 are inclined blades formed in a curved shape on the left and right sides of the vertex blades 25a, 26a (top edge) and the vertex blades 25a., 26a, respectively. It may be formed of a combination of 25b, 26b: side edge) and side edges 25c, 26c (bottom edge) extending from the ends of the inclined blades 25b, 26b to the connecting portions 21, 22, respectively.

Here, the pair of side blades 25c and 26c are for increasing the acute angle effect to be described later, and both the same length and different lengths are possible, and both straight and curved shapes are possible.

The micro cutter 20 having such a configuration is arranged along the curved upper surface of the cutter plate 10, and a plurality of cutter plates 10 are formed along the longitudinal and lateral directions. The arrangement of the micro cutters 20 can be arranged in a parallel shape as shown in FIG. 1, and it is also possible to arrange the zigzag shapes that are arranged to be offset from the neighboring micro cutters 20.

The characteristics of the micro cutter of the present invention configured as described above are as follows with reference to FIG. 6.

Figure 6 (a) shows a conventional circular-shaped micro cutter. In the conventional micro cutter, if the distance between the tops of the first and second cutting edges, that is, the vertex edges is Ha, and the curvature radius of the vertex blades at the longitudinal end of the connecting portion is Ra, Ha ≤ 2Ra + W is given. W is the width in the longitudinal direction of the connecting portion. Here, it can be seen that the diameter S of the micro cutter is equal to 2Ra. That is, the distance between the vertex blades (Ha) of the micro cutter has a shape of a microcutter having a shape equal to or smaller than the diameter of the circle, which is the radius (R) between the vertex blades at the center of the connecting portion.

However, as shown in Figure 6 (b), (c), the micro cutter 20 of the present invention satisfies the relationship of H ≥ 2R + W.

That is, in Fig. 6 (b), the distance between the vertex blades (Hb) because the first and second cutting edges (25, 26) is a semicircular shape consisting of a radius of curvature (Rb) at the longitudinal ends of the connecting portions (21, 22). Hb ≥ = 2Rb + W is established the relationship, the radius of curvature (Rb) is larger than the radius of curvature (Ra) of the conventional micro cutter of Figure 6 (a) can increase the acute angle effect.

In addition, in FIG. 6 (c), the first and second cutting edges 25 and 26 have straight or curved side blades 25c on the inclined blades 25b and 26b on both the left and right vertex blades 25a and 26a, Since the length (L) of 26c) is a semi-circular shape consisting of a radius of curvature (Rc), the relationship between vertex edges (Hc) is Hc ≥ 2Rc + W, and the radius (Rc) is shown in Fig. 6 (b) ) Even if it is equal to the radius (Rb) of the micro cutter, the length (L) of the side blade is added to increase the acute angle effect.

In other words, the first and second cutting edges 25 and 26 of the micro cutter of FIG. 6 (b) are not formed with side edges 25c and 26c in the micro cutter of FIG. 6 (c), and a vertex of a semicircle is formed. It can be seen that the configuration has only the blades 25a and 26a and the left and right inclined blades 25b and 26b.

In the present invention, the sharpening effect refers to a sharpening effect that is smaller than the original angle of the cutting edge when the blade is vertically lowered and pushed or pulled while pushing or pulling to give an angle at a diagonal angle. This is a more easily cut effect. The acute angle effect will be described with reference to FIG. 7.

7 is a partial cross-sectional view of a general knife having an upper portion UP and a lower portion LP having a cutting edge, and FIG. 7 (a) is a cross-sectional view of a typical knife, and the cutting edge has a tip angle of θ1 and three pieces The points are denoted by A, B, and C, respectively. This is the state when cutting an object while applying a force P in the vertical direction. Here, if the cutting edge is pulled by a distance D, the three points move to the positions A ', B', and C 'as shown in Fig. 7 (b) on the right side of Fig. 7, and the tip angle of the cutting edge between them is θ2 And θ2 <θ1. As described above, if the cutting edge is cut by pushing or pulling the distance D, the effect of reducing the tip angle of the cutting edge will be referred to as an 'acute effect' in the present invention.

The above-described acute angle effect will be described with reference to FIG. 8 for the micro cutter of the present invention.

8 (a) schematically shows the protruding plate 21 of one micro cutter 20 shown in FIG. 5 or 6 (c). The cutting edges 25 and 26 formed on the protruding plate 21 have the same tip angle and are formed symmetrically around the connecting portion 22. Here, Rc is the radius of curvature of the vertex edge 25a, Hc is the distance between the opposing upper and lower vertex blades 25a, 26a, and S is the distance between the opposing side edges 25c, 26c. Designate point positions ②, ③, and ④ at regular intervals on the left side based on the center point ① of the vertex blades 25a and 26a of the cutting edges 25 and 26, and symmetrically correspond to the corresponding positions ② 'and ③' on the right side. , ④ '.

Assuming that the cutting operation is performed while pushing the micro cutter 20 upward in the drawing, the cross-sectional shape of the cutting edge at the above points operates in the form of cuttings as shown in FIGS. 8 (b) and 8 (c). That is, the tip angle of the cutting edge becomes smaller or sharper as it goes to the left or right with respect to the center point ①, and thus becomes a very sharp cutting edge at points ④ and ④ '. In other words, the cutting edge is actually cut into a shape with a smaller tip angle by the acute angle effect described above. Therefore, the user can easily remove the exfoliation with a smaller force by using the exfoliator equipped with the micro cutter 20 of the present invention.

On the other hand, with reference to Figure 9 (a) to 9 (d), using the micro cutter of Figure 8 will be described that the role of the cutting edge is changed according to the direction of use of the cutting edge.

9 (a) is a case of using the exfoliator while pushing upward in the drawing, as in the micro cutter 20 of FIG. 8 (a). At this time, the vertex blades 25a, 26a become the main cutting edge for the main cutting action, and the inclined edges 25b, 26b become the sub cutting edge for the auxiliary cutting action.

9 (b) is a case of using the exfoliator while pushing upward in the drawing. At this time, the inclined edges (25b, 26b) is the main cutting edge (main edge) for the main cutting action and the vertex blades (25a, 26a) becomes a secondary cutting edge (sub edge) for the auxiliary cutting action.

9 (c) is a case of using an exfoliator while pushing upward in the drawing. At this time, the inclined edges (25b, 26b) is the main cutting edge (main edge) for the main cutting action and the vertex blades (25a, 26a) becomes a secondary cutting edge (sub edge) for the auxiliary cutting action.

Figure 9 (d) is a case of using the exfoliator while pushing in the horizontal and horizontal directions in the drawing. At this time, the side edges (25c, 26c) are the main cutting edge (main edge) for the main cutting action and the vertex edges (25a, 26a) are the sub cutting edges (sub edge) for the auxiliary cutting action.

After all, the present invention is the main cutting edge (main) cutting edge (25a, 26a), inclined blades (25b, 26b) and side blades (25c, 26c) according to the direction of use of the exfoliator equipped with a micro cutter 20 It acts as an edge) and a sub-edge, and performs a cutting operation in combination with each other, so that keratin can be easily removed.

Next, as another embodiment of the present invention, the configuration and operation of the exfoliator 1 will be described.

As shown in FIG. 1, the exfoliator 1 includes a support frame 30 on which a plurality of micro cutters 20 are arranged on the cutter plate 10, the exfoliation plate 100 and the cutter plate 10 are assembled. ), The body frame 200 on which the exfoliation plate 100 is assembled, and a cover 300 covering the exfoliation plate 100.

Meanwhile, the support frame 30 shown in FIG. 1 is coupled to the rim of the cutter plate 10 to fix the cutter plate 10 and is preferably molded by inserting the cutter plate 10 and inserts. The cross section of the cutter plate 10 is to maintain the curved surface, as shown in Figure 710, is assembled to the body frame 200 of the exfoliator (1).

As shown in Figures 2 to 3, the support frame 30 is assembled to fit into the frame 200 of the rim (31) and the exfoliator (1) surrounding the edge of the cutter plate (10) It consists of (32). The assembly 32 is in the form of a jaw that is stepped so as to be spaced inwardly at the bottom of the rim 31.

The assembly part 32 is formed to extend to a certain length for binding with the body frame 200, and one or more crimping protrusions 33 are configured on the outer circumferential surface to increase the binding force.

In addition, the support frame 30 is configured so that the user grips the grip portion 34 by hand so as to be easily disassembled from the body frame 200 and protrudes from the opposite ends of the support frame 30 in the longitudinal direction. You can.

As shown in Figure 3, the body frame 200 and the locking piece 35 may be configured to increase the binding force. The locking piece 35 may be configured at both ends opposite to the lengthwise direction of the support frame 30, that is, two at the bottom of the gripping portion 34, in line with the assembly portion 32. The locking piece 35 protrudes in the shape of a cantilever and snaps into one of a pair of concave portions (not shown) formed to face inside the body frame 200 of the exfoliator 1 through its own elastic force, respectively. Combined.

1 to 3, the gripping portion 34 is formed as a protrusion (for example, a semi-circular shape) and protrudes on the circumference of the rim 31, and is preferably opposed in the longitudinal direction of the support frame 30. It is composed on both sides.

Hereinafter, the exfoliator 1 according to an embodiment of the present invention including the exfoliation plate 100 having the micro cutter 20 according to the present invention configured as described above will be described.

As shown in Figure 7, the exfoliator 1 according to an embodiment of the present invention, the exfoliation plate 100, the exfoliation plate 100 is assembled body frame 200 and exfoliation plate 100 It is composed of a cover 300 that covers and protects the blade when not in use.

The exfoliation plate 100 is detachably assembled to the body frame 200. As a user's habit, if one of the first and second cutting edges 25 and 26 is worn using one cutting edge 25, for example, one of the first cutting edges 25, the other second cutting edge 26 that is not worn It is possible to use by assembling the exfoliation plate 100 against the body frame 200 to use.

The body frame 200 is a detachable exfoliation plate 100 is assembled detachably, and is composed of a keratin accommodating portion 210 and a handle 220 that collects keratin removed from the user's skin.

That is, the stratum corneum receiving unit 210 is a structure having a space that is open toward one side so that the stratum corneum of the exfoliation plate 100 is fitted and collected. The handle 200 is configured with a gripping groove 211 in a portion corresponding to the gripping portion 34 so that the user can easily grasp the gripping portion 34 of the exfoliation plate 100.

In general, the handle needs to have a proper volume so that it can be grasped by hand and used for power. To make the handle with plastic material, it takes too much material to satisfy the volume, or it has a problem with cooling after injection due to the thick area, or To eliminate the problem, a complex slide mold is used to make space inside.

As shown in Figure 11, the handle 220 of the present invention is configured as a semi-cylindrical shape having an outer surface curved so that the grip (grip) is comfortable, in particular, one side is open. When the user grips the lower portion of the handle 200, one or more anti-slip plates 221 may be configured to prevent slipping. The non-slip plate 221 partially protrudes into the inner space of the handle 220 to the outside of the handle 220, preferably semi-circular. When there are a large number of non-slip plates 221, they are formed in multiple stages with a gap (preferably, a gap such that a finger does not fall out). That is, the handle 220 and the anti-slip plate 221 are each made of a semi-circular shape, and thus are generally cylindrical and easy to grip.

The exfoliator 1 according to an embodiment of the present invention having the above structure has an effect of reducing the manufacturing cost because injection molding is possible only with a simple mold of an upper mold and a lower mold without a slide mold.

As shown in Figure 1, the cover 300 is detachably assembled to the exfoliation plate 100 or the frame 200. The cover 300 is intended to protect the blade of the micro cutter 20 from collision with an external object by preventing the micro cutter 20 of the exfoliation plate 100 from being exposed to the outside.

According to the present invention, when the user grips the handle 220 and pulls or pushes the exfoliation plate 100 in contact with the skin, the exfoliation is cut off from the skin by the cutting edge and removed. When the first cutting edge 25 is used to be located in the longitudinal direction of the exfoliator 1, the exfoliation plate 100 is pushed to remove the exfoliation by the first cutting edge 25 and the second is pulled in reverse. Exfoliation is removed by the cutting edge (26).

In this process, the first and second cutting edges (25, 26) are composed of the vertex blades (25a, 26a), the left and right inclined blades (25b, 26b), and the side blades (25c, 26c). The side blades 25c, 26c exfoliate when pushed or pulled at an angle to the blades 25b, 26b. Therefore, the inclined blades 25b, 26b and the side blades 25c, 26c are formed in different directions, effectively removing dead skin cells in any direction the user uses.

On the other hand, according to the embodiment of the present invention, the exfoliator 1 having various components having different shapes does not need to use the side mold used in the prior art, but only uses the upper mold and the lower mold for normal injection It can be produced by a molding method.

For example, as shown in FIG. 12, the exfoliator 1A according to another embodiment of the present invention excludes the exfoliation plate 100A having a planar cross section, that is, the gutter plate 10A having a flat outer surface. And, the exfoliation plate 100A having the same components as those disclosed in FIGS. 1 to 10 may be assembled.

In addition, as another embodiment of the present invention, when neighboring rows of the micro cutter 20 are formed in a zigzag form while being inclined with each other, the continuity of exfoliation (removal of the keratin that was not removed in the previous micro cutter in the next micro cutter) is Since it removes a large amount of keratin in a single operation, it has the effect of shortening the exfoliation time.
