  The present invention relates to a nail polisher.

A nail polish file has been proposed in which a polished surface on which a file portion is formed is curved (see, for example, Patent Document 1).
As an abrasive for nail polish, one in which abrasive grains are applied to one surface of a substrate such as paper or cloth, an adhesive layer is formed on the other surface, and a release paper is pasted on the adhesive layer has been proposed ( For example, see Patent Document 2). When using the nail polish abrasive, the release paper is peeled off and attached to a prepaid card or the like.
In addition, an electric nail polisher has also been proposed in which an abrasive can be replaced in the polishing part (see, for example, Patent Document 3).

Japanese Patent Laid-Open No. 9-9827 Japanese Utility Model Publication No. 5-51205 Japanese Utility Model Publication No. 5-39404

First, regarding how to polish the nails, there are cases where the nails of the hand and the toenails are cut at the tips and the contours of the cut portions are adjusted, and where the flat portions are polished for manicure and the like. That is, as shown in FIG. 10A, there are a case where the tip end of the nail T is cut and the cut tip end T2 is prepared, and a case where the flat portion T1 is polished. When preparing the tip T2, the case of finishing in a curved shape (round outline) like the tip T2 of FIG. 10A, and the case of finishing in a straight line (angular outline) like the tip T2 of FIG. There is. And when finishing in a straight line as in the latter case, the corners are rounded (R is added). When the nail T is cut, the shape in the thickness direction of the tip T2 of the nail T is an angular shape as shown in FIG. 10C, and the corner T21 is caught on clothes or the like, or a portion of the corner T21. Is chipped (peeled off). Therefore, it is rounded (with a taper) as shown in FIG. In the case of nail polish or the like, the flat surface portion T1 is polished to make the surface of the nail T smooth.
When polishing the nail, the curved polished surface can be relatively easily polished when the flat portion T1 of the nail T is polished or when the tip T2 is polished in a curved shape as shown in FIG. It is not easy to polish the root portion of the nail T (the boundary portion between the nail T and the skin of the finger) T3 and the corner portion T4 of the root portion, and the skin may be damaged. Further, the tip T2 of the nail T is polished linearly as shown in FIG. 10B, or R is attached to the angular portion of the outline of the tip T2, or like the corner T22 of FIG. 10D. It is not easy to add a taper. Also, since the size of the nail varies from person to person, it is not sufficient to simply bend it.

Next, regarding the nail polish, the nail polish having a conventional pressure-sensitive adhesive layer is difficult to peel off once attached to a prepaid card or the like. In addition, when the abrasive is attached to the polishing part of the electric nail polisher so as to be replaceable, it is not clear how the replacement is possible. Therefore, for example, when a nail polish abrasive having the pressure-sensitive adhesive layer is used, it is difficult to remove the abrasive once attached, and it is difficult to remove. In addition, the abrasive becomes more difficult to peel off after a certain period of time has passed since the pasting.
In view of the above problems, the present invention can select a polishing surface having a shape suitable for the location where the nail is to be polished, and can easily apply or remove the abrasive to the polishing surface, and polish the nail with the adhesive force of the abrasive. An object of the present invention is to provide a nail polisher that can be adjusted and set to such an extent that there is no hindrance.

In order to achieve the above object, the nail polisher according to claim 1 comprises a polyhedron, and the polyhedron has a plurality of polishing surfaces on which abrasive pieces are mounted, and the plurality of polishing surfaces are at least It has a planar surface and a curved surface.
The nail polish tool according to claim 2 is the nail polish tool according to claim 1, wherein the abrasive piece has a non-removable pressure-sensitive adhesive layer, and the polishing surface has adhesive force adjusting means. Features.
The nail polish tool according to claim 3 is the nail polish tool according to claim 1, wherein the abrasive piece has a re-peelable pressure-sensitive adhesive layer, and the polishing surface has no adhesive force adjusting means. Features.

The nail polisher of the present invention comprises a polyhedron, has at least a flat surface and a curved polishing surface, and an adhesive piece can be attached to the polishing surface, so when polishing the nail, the shape depends on the location to be polished. Since different polishing surfaces can be used properly, it is easy to polish the nails and finish it cleanly.
The curved surface of the polishing surface can finish the tip of the nail round, and can easily taper the round tip. Since the curved surface is in surface contact with the flat portion of the nail, the flat portion of the nail can be polished at a time. In addition, if a curved edge portion or corner portion is used, the root portion of the nail can be easily polished.
The planar surface of the polished surface can finish the tip of the nail in a straight line (angular contour). At that time, the tip of the nail can be tapered and finished, and the tip of the nail can be brought into point contact with the planar surface, which is convenient for finishing a part of the tip of the nail, for example, a corner portion. Further, if the straight edge portion or the corner portion on the upper surface of the plane is used, the root portion of the nail can be easily polished.

Since the nail polisher of the present invention can be used by attaching or replacing the abrasive pieces on the desired polished surface or the entire polished surface, the nail polisher can be used repeatedly. Further, the frequency of use of the nail polisher varies depending on the polishing surface, and the polishing material for finishing with small abrasive grains tends to decrease the polishing ability. Since the nail polisher can replace the abrasive pieces for each polishing surface, the abrasive pieces can be used effectively and economically.
Since the nail polisher of the present invention has an adhesive force adjusting means on the polishing surface, it is easy to remove a used abrasive piece even when the adhesive of the adhesive layer of the abrasive piece is of a non-removable type. Therefore, it is easy to replace the abrasive piece.
When the adhesive of the adhesive layer of the abrasive strip is of a re-peelable type, the nail polisher of the present invention can easily remove the used abrasive strip without providing an adhesive force adjusting means on the polishing surface. Therefore, it is easy to replace the abrasive piece.

An embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is used for the part common to each figure.
FIG. 1 is a diagram showing the shape of a nail polisher, FIG. 1 (a) is a perspective view, FIG. 1 (b) is a plan view, and FIG. 1 (c) is a cross-sectional view of the portion X1 in FIG. FIG.1 (d) is sectional drawing of the X2 part of Fig.1 (a).
The nail polisher 1 is composed of a hexahedron having surfaces 11 to 16. The surface 11 and the surface 12 are semi-cylindrical (rain gutter-like) curved surfaces, and the bottom portions (central portions of the curved surfaces) of both curved surfaces are formed in a crossing (orthogonal) direction. The surfaces 13 and 15 form a flat surface, and the surface 14 forms a convex curved surface. Further, the surface 16 forms a hemispherical surface 161 having a hemispherical shape (concave lens shape).
The surfaces 11 to 16 are surfaces on which abrasive pieces for polishing nails are mounted, and all six surfaces can be used as abrasive piece mounting surfaces, or a part of the surfaces can be used as abrasive piece mounting surfaces. In that case, at least a plane and a curved surface are provided. With a flat and curved surface, each part of the nail can be easily polished.

The curved surfaces of the surfaces 11 and 12 can finish the tip of the nail round, and can easily taper the round tip. Since the curved surface is in surface contact with the flat portion of the nail, the flat portion of the nail can be polished at a time. If the curved edge portions or corner portions of the surfaces 11 and 12 are used, the root portion of the nail can be easily polished. Since the curved surfaces of the surfaces 11 and 12 have different bending directions, the contact direction and angle between the tip of the nail and the abrasive piece can be changed when the nail is polished, and the curvatures of the curved surfaces of the surfaces 11 and 12 are made different. The surface that can be easily polished can be selected according to the size of the nail.
Since the surface 13 is a flat surface, the tip of the nail can be finished in a straight line (angular outline). At this time, the tip of the nail can be tapered and finished, and the tip of the nail can be brought into point contact with the surface 15, which is convenient for finishing a part of the tip of the nail, for example, a corner portion. Further, if the straight edge portions or corner portions of the surfaces 11 and 12 are used, the root portion of the nail can be easily polished.

Since the surface 14 is a convex curved surface, the tip or flat surface of the nail can be point-contacted or line-contacted with the surface 14, and if the edge portion curved to the outside of the surface 14 is used, the root of the nail The part can be polished without touching the skin.
Since the surface 16 has a hemispherical surface 161, if this hemispherical surface 161 is used, the tip of the nail can be rounded, and at the same time, a taper can be attached.
Here, the semi-cylindrical shape is not limited to a strict half cylindrical shape, and may be a cylindrical portion. The cylindrical shape is not limited to a true cylindrical shape, and may be an elliptical cylindrical shape. The hemispherical shape is not limited to a strict half spherical shape, and may be a spherical portion. The spherical shape is not limited to a true spherical shape, and may be an elliptical spherical shape.
When using the nail polisher 1, hold the nail polisher 1 with an abrasive piece in hand and select a plane, curved surface, hemispherical surface, convex curved surface, etc. according to the location of the nail to polish. polish.

  The structure of the abrasive piece mounting surface is formed in accordance with the mounting means of the abrasive piece to be mounted. As the means for attaching the abrasive piece, there are one using an adhesive means and one using a magnetic means. For the adhesive means, one having a pressure-sensitive adhesive layer formed on one surface of the abrasive piece is used. For the pressure-sensitive adhesive, once bonded, it is not easy to peel off again (permanent bonding type) and once bonded. There is a type that can be easily peeled later. Therefore, in the present application, the former is referred to as a non-removable adhesive, and the latter is referred to as a removable adhesive. The re-peelable pressure-sensitive adhesive is used for sticky notes with pressure-sensitive adhesive (see, for example, Japanese Patent Laid-Open Nos. 2000-218961 and 2003-19880), and is used to temporarily fix a sticky note or the like to a document or the like. ing. Non-removable pressure-sensitive adhesives are used for labeling of documents and the like (for example, “Chemistry and Application of Adhesion and Adhesion”, page 213 (Edited by The Chemical Society of Japan, February 5, 1998, Dai Nippon Books) Issue)).

When the adhesive layer of the abrasive strip is non-removable, a release layer (release liner) made of a release agent such as silicone or Teflon (registered trademark) is formed on each surface of the nail polisher 1. As will be described later, the release layer is formed, for example, by alternately forming a portion where silicone or the like is applied and a portion where it is not applied, and adjusts the adhesive force by changing the area ratio of both. In the case where the pressure-sensitive adhesive layer of the abrasive piece is a re-peelable type, the adhesive force of the pressure-sensitive adhesive layer is small, so that no release layer is formed.
When a release layer is formed on each surface of the nail polisher 1 or when the adhesive layer of the abrasive strip is a re-peelable type, the adhesive force of the abrasive strip is small, but when polishing the nail, the abrasive Since the piece is pressed against the nail polisher 1 with a nail and the abrasive piece mounting surface of the nail polisher 1 has resistance to movement (sliding) of the abrasive piece by the adhesive, the abrasive piece is peeled off, There is no movement.
When using magnetic means as the means for mounting the abrasive piece, use a magnetic material for the nail polisher 1 and the abrasive piece and magnetize both magnetic materials, or magnetize one magnetic material, The abrasive piece is mounted on the abrasive piece mounting surface of the nail polisher 1.

FIG. 2 is an example in which the nail polisher 1 is formed of a cylindrical polyhedron. 2 (a), (c), and (e) are perspective views, and FIGS. 2 (b), (d), and (f) are cross-sectional views of the portion X3 in FIGS. 2 (a), (c), and (e). It is.
2A and 2B, the opposing surfaces 11 and 13 are formed into a curved surface and a flat surface, respectively, and the entire outer peripheral surface 17 is formed into a curved surface shape. The bottom portion of the curved surface of the surface 11 is flat, but the bottom of the curved surface of the outer peripheral surface 17 is arcuate (bent in the circumferential direction), so the outer peripheral surface 17 is a curved surface and a convex surface. Will have both.
2 (c) and 2 (d), the surface 11 is formed as a hemispherical surface in FIGS. 2 (a) and 2 (b).
2 (e) and 2 (f), four partial curved surfaces 171 and partial convex curved surfaces 172 are formed on the surface 17 in FIGS. 2 (a) and 2 (b). In the case of this example, it is possible to make it easier to use by changing the curvature of the partially curved surface 171 and the partially convex curved surface 172 for each portion.

In FIG. 3, partial surfaces having a plurality of shapes are formed on a part of the hexahedron.
FIG. 3A shows an example in which two partial curved surfaces 111 and 112 and one partial plane 113 curved in the same direction are formed on the surface 11. The partially curved surfaces 111 and 112 may have different curvatures. The partially curved surfaces 111 and 112 can also be used for mounting abrasive pieces having different abrasive grain sizes.
FIG. 3B shows an example in which two partial curved surfaces 111 and 112 and one partial hemispherical surface 113 are formed on the surface 11. The partially curved surfaces 111 and 112 are formed so that the bending directions are orthogonal.

FIG. 4 is a diagram illustrating a configuration example of a release layer of the nail polisher.
4A is a perspective view of the nail polisher, and FIG. 4B is a cross-sectional view of the portion X1 in FIG. 4A.
FIG. 4A and FIG. 4B are examples in which abrasive pieces are mounted on the surface 11 and the surface 13.
The substrate 4 is made of hard plastic, ceramics, metal, wood, etc., and is formed by forming elastic material layers 31 and 32 such as sponge and rubber on the surface, and further laminating release layers 21 and 22 made of silicone or the like. It is.
Since the elastic material layers 31 and 32 are interposed between the base material 4 and the release layers 21 and 22, when the abrasive piece is attached and the nail is polished, the abrasive piece wraps around the nail. When polishing the tip, the corner of the nail is finished smoothly. Also, when polishing the flat part of the nail, if the nail has a vertical or horizontal groove, the groove part can be easily polished.
FIG. 4C is an example in which the elastic material layers 31 and 32 of FIG. 4B are not provided. In the case of this example, when polishing the nail, for example, the tip of the nail is in point contact with the polishing piece on the flat surface 13 and in line contact with the curved surface 11, so that the root of the nail and a part of the tip are polished. convenient.
FIG. 4D shows an example in which the release layer and the elastic material layer shown in FIGS. 4A and 4B are formed on the entire surface of the substrate 4.
4 (a), 4 (b), and 4 (c), when the substrate 4 is made of an elastic material such as sponge or rubber, the elastic material layer can be omitted.

FIG. 5 shows the adhesive force adjusting means for the abrasive piece mounting surface of the nail polisher when the adhesive layer of the abrasive piece is non-peelable.
5 (a) and 5 (b) are examples in which a release layer is formed by mixing a part where the release agent is applied and a part where the release agent is not applied to the abrasive piece mounting surface of the nail polisher. FIG. The part S where the release agent is applied and the part (base material part) B where the release agent is not applied are alternately formed, and FIG. 5B shows the part B where the release agent is not applied to the part S where the release agent is applied. It is exposed in a circular shape. The adhesive strength of the surface on which the abrasive piece of the nail polisher is mounted can be adjusted by changing the width of the portion S where the release agent is applied and the portion B where the release agent is not applied, and changing the area ratio between them. That is, the greater the area ratio of the portion B where the release agent is not applied, the greater the adhesive force. Further, when the area of the portion B where the release agent is not applied is 0, the adhesive strength is the smallest.
5 (c) and 5 (d), instead of forming a release layer, a large number of protrusions (warts) Bt are formed on the substrate B. FIGS. 5 (e) and 5 (f) are sawtooth protrusions. (Mountain protrusions) A large number of Bt are formed. In either case, the adhesive force is adjusted by changing the number of protrusions Bt or the area of the top.
