Description

本願発明は、研磨材片を爪切りに張付けて使用する爪切り用研磨材とその爪切り用研磨材片を張付ける爪切りに関する。   The present invention relates to a nail clipper abrasive material that is used by sticking an abrasive strip to a nail clipper, and a nail clipper that stretches the nail clipper abrasive strip.

従来爪磨き用研磨材として、紙、布等の基材の一面に砥粒を塗布し、他面に粘着剤層を形成し、その粘着剤層に剥離紙を張付けたものが提案されている（例えば特許文献１参照）。爪磨き用研磨材は、使用するとき剥離紙を剥して、プリペードカード等に張付けて使用する。
また電動式爪磨き機において、研磨部に研磨材を張替え可能に張付けるものが提案されている（例えば特許文献２参照）。
また従来の爪切りは、一般に爪を磨くヤスリ部を有している。 Conventional nail polish abrasives have been proposed in which abrasive grains are applied to one side of a substrate such as paper or cloth, an adhesive layer is formed on the other side, and release paper is applied to the adhesive layer. (For example, refer to Patent Document 1). 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 been proposed in which an abrasive is attached to a polishing portion so as to be replaceable (see, for example, Patent Document 2).
Conventional nail clippers generally have a file portion for polishing the nail.

従来の粘着剤層を有する爪磨き用研磨材は、プリペードカード等に一度張付けると剥すことは困難である。また電動式爪磨き機の研磨部に研磨材を張替え可能に張付ける場合、どのようにすれば張替え可能になるのか明らかでない。そこで例えば前記プリペードカード等に張付ける粘着剤層を有する爪磨き用研磨材を使用すると、一度張付けた研磨材を剥すのが大変で、剥すに苦労する。また研磨材は、張付けてから次の張替えまでに時間が過ぎると、一層剥し難くなる
従来の爪切りのヤスリ部は、金属に溝等を形成したものであるため、爪を削りすぎたり、またヤスリ目が粗いため爪に傷ができたり、爪が割れたりすることがあり、きれいに仕上がらない。特に子供の爪の場合には、危険を伴う。また従来の爪切りのヤスリ部は、カットした爪の先端を磨くことはできるが、爪の平らな部分を磨くのは難しい。またヤスリ部は、使用している間に磨耗して磨き難くなる。
A conventional nail polish abrasive having an adhesive layer is difficult to remove 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 an abrasive for nail polish having an adhesive layer to be attached to the prepaid card or the like is used, it is difficult to remove the abrasive once attached, and it is difficult to remove. In addition, the abrasive material becomes more difficult to peel off after a certain period of time from pasting until the next re-stretching.The conventional nail clipper filed is formed by forming grooves or the like in the metal. Since the file is rough, the nail may be scratched or the nail may be cracked. Especially in the case of children's nails, it is dangerous. In addition, the conventional nail clippers can polish the tip of the cut nail, but it is difficult to polish the flat part of the nail. Further, the file portion is worn during use and is difficult to polish.

本願発明は、前記問題点に鑑み、爪切りに研磨材を簡単に張付けたり剥したりでき、かつ研磨材の接着力を爪を磨くのに支障がない程度に調整して設定することができ、爪を安全にきれいに磨くことができ、爪の先端のみでなく平らな部分も磨くことができる爪磨き用研磨材と爪切りを提供することを目的とする。   In view of the above problems, the invention of the present application can be set by adjusting the adhesive strength of the abrasive to such an extent that there is no hindrance to polish the nail, and can easily stick or remove the abrasive to the nail clipper, An object of the present invention is to provide a nail polisher and a nail clipper that can polish a nail safely and cleanly and can polish not only the tip of the nail but also a flat part.

本願発明は、前記目的を達成するため、請求項１に記載の爪切り用研磨材は、基材の一面に研磨材層を形成し、他方の面に再剥離型又は非再剥離型の粘着剤からなる粘着剤層を形成してあり、爪切りに張付けて使用する研磨材片を、一枚の剥離紙に複数張付けてあることを特徴とする。
請求項２に記載の爪切り用研磨材は、請求項１に記載の爪切り用研磨材において、前記粘着剤層は、非再剥離型の粘着剤からなり、前記爪きりの接着力調整手段に張付けて使用することを特徴とする。
請求項３に記載の爪切り用研磨材は、請求項１又は請求項２に記載の爪切り用研磨材において、前記爪切りは、少なくとも平面状と湾曲状の研磨材片張付面を有することを特徴とする。
請求項４に記載の爪切りは、基材の一面に研磨材層を形成し、他方の面に再剥離型又は非再剥離型の粘着剤からなる粘着剤層を形成してある研磨材片の少なくとも平面状と湾曲状の張付面を有することを特徴とする。 In order to achieve the above object, the nail clipper abrasive according to claim 1 has an abrasive layer formed on one surface of a substrate and a re-peelable or non-re-peelable adhesive on the other surface. A pressure-sensitive adhesive layer made of an agent is formed, and a plurality of abrasive pieces to be used by being attached to a nail clipper are attached to a piece of release paper.
The nail clipper abrasive according to claim 2 is the nail clipper abrasive according to claim 1, wherein the pressure-sensitive adhesive layer is made of a non-removable pressure-sensitive adhesive, and the nail clipper adhesive force adjusting means It is characterized by being used by being attached to.
The nail clipper abrasive according to claim 3 is the nail clipper abrasive according to claim 1 or 2, wherein the nail clipper has at least a flat and curved abrasive-stretched surface. It is characterized by that.
5. The nail clipper according to claim 4, wherein an abrasive layer is formed on one surface of the substrate and an adhesive layer made of a re-peelable or non-removable pressure-sensitive adhesive is formed on the other surface. It has at least a flat and curved sticking surface.

本願発明の爪磨き用研磨材は、爪切りに簡単に張付け、簡単に剥すことができるから、張替えが簡単になる。したって剥離紙に多数の研磨材片を張付けたシートを用い、爪を磨くとき、シートから所望の研磨材片を剥して爪切りに張付けて使用することができる。また爪を磨く場所や仕上げの状態に応じて、所望の大きさの砥粒からなる研磨材片を剥し、その研磨材片を爪切りに張付けて使用できるから、爪磨きを効率的に行うことができ、かつ爪をきれいに仕上げることができる。
また本願発明の爪磨き用研磨材は、粘着剤層の粘着剤が再剥離型のものであっても、非再剥離型のものであっても使用することができる。即ち粘着剤が再剥離型の場合には、爪切りに粘着力調整手段を設けることなく使用でき、非再剥離型の場合には、爪切りに粘着力調整手段を設けることにより使用できる。そして粘着力調整手段が剥離紙を使用するものの場合には、その剥離紙を使用するか否かを選択するのみで、両型の粘着剤からなる粘着剤層を有する研磨材片を同じ爪切りに使用できる。 The polishing material for nail polish according to the present invention can be easily applied to the nail clipper and can be easily peeled off. Therefore, when a sheet in which a large number of abrasive pieces are stuck to release paper is used to polish a nail, the desired abrasive piece can be peeled off from the sheet and attached to a nail clipper. Also, depending on the location where the nail is polished and the finishing condition, the abrasive piece made of abrasive grains of the desired size can be peeled off and the abrasive piece attached to the nail clipper for use, so that nail polishing can be done efficiently Can finish nails neatly.
The nail polish abrasive of the present invention can be used regardless of whether the pressure-sensitive adhesive in the pressure-sensitive adhesive layer is a re-peelable type or a non-re-peelable type. That is, when the pressure-sensitive adhesive is a re-peeling type, it can be used without providing an adhesive force adjusting means for the nail clipper, and when it is a non-removable type, it can be used by providing an adhesive force adjusting means for the nail clipper. And when the adhesive force adjusting means uses release paper, it is only necessary to select whether or not to use the release paper, and the abrasive piece having the adhesive layer made of both types of adhesive is cut into the same nail clippers. Can be used for

爪磨き用研磨材の使用頻度は、使用する爪切りの研磨面や砥粒の大きさによって異なるが、本願発明の爪切り及び爪磨き用研磨材片は、張替えが必要な研磨材片のみ張替えればよいから、研磨材片を有効に経済的に使用できる。また研磨材片は、砥粒の大きさによって使用する頻度が異なり、張替え頻度も異なるから、シート毎に砥粒の大きさが異なるものを複数シート一組にして使用すれば、より使い易くなる。
本願発明の爪切りは、爪を磨くのに適した大きさの砥粒からなる研磨材片を張付けて使用するから、従来の金属製ヤスリのように爪を削りすぎたりすることなく、安全にきれいに仕上げることができる。 The frequency of use of nail polish is different depending on the polishing surface of the nail clipper used and the size of the abrasive grains. Therefore, the abrasive piece can be used effectively and economically. In addition, the frequency of use of the abrasive pieces differs depending on the size of the abrasive grains, and the frequency of changing the tension is also different. Therefore, it is easier to use a plurality of sheets with different abrasive grain sizes for each sheet. .
Since the nail clipper of the present invention is used by sticking an abrasive piece made of abrasive grains of a size suitable for polishing the nail, it can be safely done without scraping the nail like a conventional metal file. It can be finished neatly.

本願発明の爪切りは、研磨材片張付面を有し、その研磨材張付面は、平面状、湾曲状、球面状、凸状曲面等、異なる形状を有するから、爪の磨く場所に対応した形状の研磨材張付面に、研磨材片を張付けたり剥がしたりして使用できる。したがって本願発明の爪切りは、爪をカットした後爪を効率よく安全に磨くことができ、きれいに仕上げることができる。即ち爪の先端を丸く、或は直線状に磨くことができ、かつ爪の厚み方向にテーパーも付けることができ、爪の先端の角や爪の付根の部分も容易に安全に磨くことができる。また爪の平らな部分は、一度に広い面積を効率よく磨くことができる。   The nail clipper of the present invention has an abrasive piece-clad surface, and the abrasive-clad surface has different shapes such as a flat shape, a curved shape, a spherical shape, a convex curved surface, etc. Abrasive material pieces can be attached to or peeled off from a correspondingly shaped abrasive material application surface. Therefore, the nail clipper of the present invention can polish the nail efficiently and safely after cutting the nail and can finish it cleanly. That is, the tip of the nail can be rounded or straightened, and can be tapered in the thickness direction of the nail, and the corner of the nail and the root of the nail can be easily and safely polished. . Moreover, the flat part of the nail can efficiently polish a large area at a time.

図１〜図４により本願発明の実施例を説明する。なお各図に共通な部分は同じ符号を使用している。
図１は、研磨材の構成を示す。図１（ａ）は、多数の研磨材片を張付けた一枚のシートの平面図、図１（ｂ）は、図１（ａ）のＸ２部分の断面図である。図１（ｃ）〜（ｆ）は、図１（ｂ）のＸ３部分の拡大図である。
まず図１（ａ）〜（ｃ）について説明する。
シート１は、剥離紙（剥離ライナー）１１と多数の研磨材片１２からなる。剥離紙１１には、多数の研磨材片１２を張付けてある。剥離紙１１は、紙や布等の基材１１１にシリコーン等の剥離剤を塗布する等剥離処理して剥離層１１２を形成してある。研磨材片１２は、紙、布、不織布、プラスチックフィルム等の基材１２２の一方の面にダイヤモンド等の砥粒層１２１を形成し、他方の面に再剥離型粘着剤層１２３ａを形成してある。 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 shows the structure of the abrasive. FIG. 1A is a plan view of one sheet on which a large number of abrasive pieces are stuck, and FIG. 1B is a cross-sectional view of a portion X2 in FIG. FIGS. 1C to 1F are enlarged views of a portion X3 in FIG.
First, FIGS. 1A to 1C will be described.
The sheet 1 includes a release paper (release liner) 11 and a large number of abrasive pieces 12. A large number of abrasive pieces 12 are attached to the release paper 11. The release paper 11 has a release layer 112 formed by a release treatment such as applying a release agent such as silicone to a substrate 111 such as paper or cloth. The abrasive strip 12 is formed by forming an abrasive grain layer 121 such as diamond on one surface of a base material 122 such as paper, cloth, nonwoven fabric, or plastic film, and forming a releasable adhesive layer 123a on the other surface. is there.

ここで粘着剤について説明する。粘着剤には、一旦接着すると再度剥離するのが容易でないタイプ（永久接着タイプ）と、一旦接着した後も容易に剥離できるタイプとがあり、一般に慣用されている。そこで本願では、前者を非再剥離型粘着剤と呼び、後者を再剥離型粘着剤と呼ぶ。再剥離型粘着剤は、粘着剤付き付箋等に用いられており（例えば特開２０００―２１８９６１号公報、特開２００３―１９８８０号公報参照）、付箋等を書類等に仮止めするのに使われている。また非再剥離型粘着剤は、商品の価格表示ラベル等に用いられている（例えば、「接着と粘着の化学と応用」第２１３頁（日本化学会編、１９９８年２月５日大日本図書発行）参照）。
図１（ｃ）の研磨材片１２は、再剥離型粘着剤層１２３ａを有するから、後述する接着力調整手段を施さない爪切りに張付けるとができる。すなわち再剥離型粘着剤層１２３ａは、接着力が小さいから接着力調整手段を設けない爪切りに張付けても、簡単に剥すことができる。一方爪を磨くときは、研磨材片を爪で爪切りに押付けて使い、かつ爪切りの研磨材片張付面には、粘着剤による研磨材片の移動（摺動）抵抗があるから、爪を磨く間に研磨材片が剥がれたり、移動したりすることはない。 Here, the adhesive will be described. There are two types of pressure-sensitive adhesives that are not easily peeled once (permanent bonding type) and those that can be easily peeled after once being bonded. 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 a sticky tag with a 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 to a document or the like. ing. Non-removable pressure-sensitive adhesives are used for product price labeling labels and the like (for example, “Chemistry and Application of Adhesion and Adhesion”, page 213 (The Chemical Society of Japan, February 5, 1998, Dai Nippon Books). Issue)).
Since the abrasive piece 12 of FIG. 1C has the re-peelable pressure-sensitive adhesive layer 123a, it can be attached to a nail clipper without applying an adhesive force adjusting means described later. That is, the re-peelable pressure-sensitive adhesive layer 123a can be easily peeled even if it is attached to a nail clipper that does not have an adhesive strength adjusting means because of its low adhesive strength. On the other hand, when polishing the nail, the abrasive piece is pressed against the nail clipper with the nail, and the abrasive piece tensioning surface of the nail clipper has resistance to movement (sliding) of the abrasive piece by the adhesive, While the nail is being polished, the abrasive pieces do not peel off or move.

つぎに図１（ｄ），（ｅ）について説明する。
図１（ｄ）の研磨材片１２には、非再剥離型粘着剤層１２３ｂを形成してある。非再剥離型粘着剤層１２３ｂは、接着力が大きいから、通常の爪切りに張付けると剥すのが容易でない。そこで非再剥離型粘着剤層１２３ｂを有する研磨材片１２を張付ける爪切りの場合には、後述する接着力調整手段を設ける。
図１（ｅ）の研磨材片１２には、図１（ｄ）と同様に非再剥離型粘着剤層１２３ｂを形成してあるが、図１（ｅ）の場合には、基材１２２に粘着剤層１２３ｂを塗布した部分と塗布しない部分とを混在させてある。したがって粘着剤層１２３ｂを塗布した部分と塗布しない部分との比率を変えることにより、接着強度を変えることができる。
図１（ｆ）は、砥粒層１２１と基材１２２の間にゴム等の弾性材層１２４を設けた例である。この場合には、爪を磨くとき、爪を弾性材層１２４に押込むようになるため、爪の周囲を砥粒が包み込む格好になり、爪を丸く磨くことができる。 Next, FIGS. 1D and 1E will be described.
A non-removable pressure-sensitive adhesive layer 123b is formed on the abrasive piece 12 in FIG. The non-re-peelable pressure-sensitive adhesive layer 123b has a large adhesive force, and therefore it is not easy to peel it off when attached to a normal nail clipper. Therefore, in the case of nail clipping with the abrasive strip 12 having the non-removable pressure-sensitive adhesive layer 123b, an adhesive force adjusting means described later is provided.
The non-removable pressure-sensitive adhesive layer 123b is formed on the abrasive piece 12 in FIG. 1 (e) as in FIG. 1 (d). In the case of FIG. A portion where the adhesive layer 123b is applied and a portion where the adhesive layer 123b is not applied are mixed. Therefore, the adhesive strength can be changed by changing the ratio between the portion where the adhesive layer 123b is applied and the portion where the adhesive layer 123b is not applied.
FIG. 1F shows an example in which an elastic material layer 124 such as rubber is provided between the abrasive grain layer 121 and the base material 122. In this case, when the nail is polished, the nail is pushed into the elastic material layer 124, so that the abrasive grains are wrapped around the nail and the nail can be polished round.

図１のシート１は、砥粒の大きさが異なる研磨材片によって構成すると、爪を磨くとき、きめの粗い研磨材片ときめの細かい研磨材片を使い分けることができる。その場合、一枚のシートの研磨材片は、全て同じ大きさの砥粒で形成し、シート毎に砥粒の大きさが異なるようにしてもよいし、一枚のシートに砥粒の大きさが異なる研磨材片を混在させてもよい。研磨材片は、砥粒の大きさによって使用する頻度が異なり、張替え頻度も異なるから、シート毎に砥粒の大きさが異なるものを複数シート一組にして使用すると使い易い。
図１のシート１には、剥離紙１１に多数の研磨材片１２を一枚一枚独立して形成してあるが、一枚の剥離紙１１に一枚の研磨材を形成し、その研磨材に縦横に所定の間隔でミシン目を形成して所定の大きさに切取ることができるように構成して、多数の研磨材片を連続させて形成することもできる。その場合、ミシン目は、研磨材にのみ形成してもよいし、剥離紙を含めて形成してもよい。このように研磨材片を連続した形に形成すれば、研磨材の形成が効率的になるし、剥離紙を有効に利用できる。また研磨材片は、それを張付ける場所の大きさに応じた大きさに切断することができから、研磨材を効率よく使用でき、かつ使い易くなる。 When the sheet 1 of FIG. 1 is composed of abrasive pieces having different abrasive grain sizes, when polishing the nail, the coarse abrasive piece and the fine abrasive piece can be used properly. In that case, all the abrasive pieces of one sheet may be formed with the same size abrasive grains, and the size of the abrasive grains may be different for each sheet, or the size of the abrasive grains on one sheet Abrasive pieces of different sizes may be mixed. Since the abrasive piece has a different frequency of use depending on the size of the abrasive grains and also has a different frequency of tensioning, it is easier to use a plurality of sheets having different abrasive grain sizes for each sheet.
In the sheet 1 of FIG. 1, a large number of abrasive pieces 12 are independently formed on the release paper 11 one by one. However, one abrasive is formed on one release paper 11 and the polishing is performed. A number of abrasive pieces can be formed continuously by forming perforations in the material at predetermined intervals in the vertical and horizontal directions and cutting them into a predetermined size. In that case, the perforations may be formed only on the abrasive or may be formed including the release paper. If the abrasive pieces are formed in a continuous shape in this way, the formation of the abrasive becomes efficient, and the release paper can be used effectively. Further, since the abrasive piece can be cut into a size corresponding to the size of the place where the abrasive piece is attached, the abrasive can be used efficiently and becomes easy to use.

図２は、図１の研磨材片（粘着剤層は非再剥離型と再剥離型）を張付ける爪切りの構成例を示す。
図２（ａ）は、爪切りの側面図である。爪きり２は、操作テコ体２１と刃体２２，２３とからなる。刃体２２，２３の双方又はいずれか一方の外側の面に研磨材片を張付ける。操作テコ体２１に張付けることもできる。
ここでは、刃体２３を例に説明する。
図２（ｂ）の刃体２３は、平面状の研磨材片張付面を有し、図２（ｃ）の刃体２３は、広い研磨材片張付面２３ａを有する。研磨材片張付面２３ａは、円形、楕円形等他の形状であってもよい。図２（ｃ）の場合には、研磨材片張付面が広くなるから、爪を磨き易くなる。研磨材片張付面２３ａは、後述する凸状曲面、湾曲面、球面状曲面等に形成することもできる。
図２（ｄ）の刃体２３は、外側（刃体２２と反対側）へ突出した凸状曲面の研磨材片張付面２３ｂを有し、図２（ｅ）の刃体２３は、内側（刃体２２側）へ湾曲した湾曲面の研磨材片張付面２３ｃを有する。
図２（ｆ）の刃体２３は、内側（刃体２２側）へ窪んだ球面状曲面（レンズ状曲面）の研磨材片張付面２３ｄを有する。 FIG. 2 shows a configuration example of a nail clipper for attaching the abrasive strip of FIG. 1 (the adhesive layer is a non-removable type and a removable type).
Fig.2 (a) is a side view of a nail clipper. The nail clipper 2 includes an operation lever body 21 and blade bodies 22 and 23. An abrasive piece is stuck on the outer surface of both or one of the blade bodies 22, 23. It can also be attached to the lever lever 21.
Here, the blade body 23 will be described as an example.
The blade body 23 in FIG. 2 (b) has a planar abrasive piece-clamping surface, and the blade body 23 in FIG. 2 (c) has a wide abrasive piece-clamping surface 23a. The abrasive piece tensioning surface 23a may have other shapes such as a circle and an ellipse. In the case of FIG.2 (c), since an abrasive | polishing material piece sticking surface becomes large, it becomes easy to polish a nail | claw. The abrasive piece tensioning surface 23a can also be formed into a convex curved surface, a curved surface, a spherical curved surface, etc., which will be described later.
The blade body 23 in FIG. 2 (d) has a convexly curved abrasive-stretching surface 23b protruding outward (opposite to the blade body 22), and the blade body 23 in FIG. It has an abrasive-stretched surface 23c having a curved surface curved toward the blade body 22 side.
The blade body 23 in FIG. 2 (f) has a spherically curved surface (lens-shaped curved surface) abrasive-stretching surface 23d that is recessed inward (to the blade body 22 side).

研磨材片張付面は、図２（ｂ）〜図２（ｆ）の部分に限らず、例えば、図２（ｃ）の研磨材片張付面２３ｃの両側に広げてもよい。その場合には、１個の刃体２３が湾曲状の研磨材片張付面と平面状の研磨材片張付面とを併せ持つことになり、爪磨きが容易になる。
前記研磨材片張付面は、操作テコ体２１、刃体２２，２３に夫々形成し、各研磨材片張付面の形状を相違させることもできる。例えば、刃体２２の研磨材片張付面は、平面状にし、刃体２３の研磨材片張付面は内側へ湾曲した湾曲面にし、操作テコ体２１の研磨材片張付面は、球面状曲面にする。また大きい爪切りの場合には、例えば、刃体２２に湾曲面と球状曲面の２種類の研磨材片張付面を形成することもできる。これらの場合には、１個の爪切りが、複数の形状の研磨材片張付面を有することになるから、爪の磨く場所に都合のよい平面や曲面を選択でき、爪磨きが容易になる。研磨材片張付面は、少なくとも平面状の面と湾曲面があると都合がよい。 The abrasive material tensioning surface is not limited to the portions shown in FIGS. 2B to 2F, and may be spread on both sides of the abrasive material tensioning surface 23c in FIG. 2C, for example. In this case, one blade body 23 has both a curved abrasive piece-attached surface and a flat abrasive piece-attached surface, so that nail polishing is facilitated.
The abrasive piece-clamping surfaces can be formed on the operation lever body 21 and the blade bodies 22, 23, respectively, and the shapes of the respective abrasive piece-clad surfaces can be made different. For example, the abrasive material tensioning surface of the blade body 22 is flat, the abrasive material tensioning surface of the blade body 23 is a curved surface curved inward, and the abrasive material tensioning surface of the operation lever 21 is Make spherical curved surface. Further, in the case of a large nail clipper, for example, two types of abrasive-stretching surfaces of a curved surface and a spherical curved surface can be formed on the blade body 22. In these cases, since one nail clipper has a plurality of shapes of abrasive-stretched surfaces, it is possible to select a plane or curved surface that is convenient for the location where the nail is to be polished, making it easy to polish the nail Become. Conveniently, the abrasive stripping surface has at least a planar surface and a curved surface.

ここで爪の磨き方についてみると、図４（ａ）のように爪Ｔの先端をカットした後、そのカットした先端Ｔ２を整える場合と、平らな部分Ｔ１を磨く場合とがある。先端Ｔ２を整える場合、図４（ａ）の先端Ｔ２のように曲線状（丸い輪郭）に仕上げる場合と、図４（ｂ）の先端Ｔ２のように直線状（角張った輪郭）に仕上げる場合とがある。そして後者の場合のように直線状に仕上げる場合にも、角部は丸く仕上る（Ｒを付ける）。また爪Ｔをカットしたとき、爪Ｔの先端Ｔ２の厚み方向の形状は、図４（ｃ）のように角張った形状になり、角部Ｔ２１が衣服等に引っ掛かったり、角部Ｔ２１の部分が欠けたり（剥がれたり）する。そのため図４（ｄ）の角部Ｔ２２のように丸く（テーパーを付けて）仕上げる。また爪Ｔの付根部分（爪Ｔと指の皮膚の境部分）Ｔ３や付根部分の角部Ｔ４を磨いたりするのは容易でなく、かつ皮膚に傷をつけないように留意しなければならない。   Here, as to how to polish the nail, after cutting the tip of the nail T as shown in FIG. 4A, there are a case where the cut tip T2 is prepared and a case where the flat portion T1 is polished. When preparing the tip T2, the case where it is finished in a curved shape (round outline) like the tip T2 in FIG. 4A, and the case where it is finished in a straight shape (angular outline) like the tip T2 in FIG. There is. And even when finishing in a straight line as in the latter case, the corners are rounded (R is added). Further, 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. 4C, and the corner T21 is caught on clothes or the like, and the corner T21 is It is chipped (peeled off). Therefore, it is rounded (tapered) like the corner portion T22 in FIG. Further, it is not easy to polish the root portion of the nail T (the boundary portion between the nail T and the finger skin) T3 and the corner portion T4 of the root portion, and care must be taken not to damage the skin.

爪を磨くとき、爪切りに研磨材片を張付けた面（研磨面）が平面状の場合には、爪と線接触或は点接触するから、爪の先端Ｔ２を直線状に仕上げたり、その直線状の先端に厚み方向のテーパーを付けたり、角部分を磨いたりするのに都合がよい。凸状曲面の研磨面は、爪と小さな点で点接触、或は細い線で線接触するから、平面状の場合よりも細かな仕上げが可能になる。湾曲状の研磨面は、爪と曲線状或は直線状に線接触し、また面接触や点接触もするから、爪の先端を丸く仕上げたり、先端に爪の厚み方向のテーパーを付けたり、平らな部分を磨いたり、角部分を仕上げたりするのに都合がよい。球面状の研磨面は、爪の先端と弧状に線接触するから、爪の先端を丸く仕上げ、同時に爪の厚み方向にテーパーを付けて仕上げるのに都合がよい。また爪の付根の部分は、前記各形状の研磨面の縁の部分や角の部分を使って磨くことができる。   When polishing the nail, if the surface of the nail clipper with the abrasive piece (polished surface) is flat, it will be in line contact or point contact with the nail. It is convenient for attaching a taper in the thickness direction to a straight tip or polishing a corner portion. Since the convex curved polishing surface is in point contact with the nail at a small point or line contact with a thin line, finer finishing is possible than in the case of a flat surface. The curved polished surface is in line contact with the nail in a curved or straight line, and also makes surface contact and point contact, so the tip of the nail is rounded, or the tip is tapered in the thickness direction of the nail, Convenient for polishing flats and finishing corners. Since the spherical polished surface is in line contact with the tip of the nail in an arc shape, it is convenient to finish the tip of the nail round and simultaneously taper the nail in the thickness direction. Further, the root portion of the nail can be polished using the edge portion or the corner portion of the polishing surface of each shape.

図３は、研磨材片の粘着剤層が非再剥離型の場合における、爪切りの接着力調整手段を示す。
図３（ａ）は、刃体２３に接着力調整手段３を設けた例を示す。
図３（ｂ），（ｃ）は、剥離紙（剥離ライナー）からなる接着力調整手段３を設けた例を示す。刃体２３には、剥離紙３１を張付けてある。剥離紙３１は、基材３１２の一方の面に剥離剤層３１１を、他方の面に粘着剤層３１３を形成し、粘着剤層３１３を刃体２３に張付けてある。粘着剤層３１３の粘着剤は、非再剥離型のものを使用する。爪を磨くときは、剥離剤層３１１に研磨材片を張付ける。図３（ｂ）は、剥離剤層を連続して形成した例であり、図３（ｃ）は、剥離剤層を不連続で形成した例である。図３（ｃ）の場合には、剥離剤層を形成した部分と形成しない部分の比率を変えることにより、研磨材片の接着力を調整できる。
図３（ｂ），（ｃ）の場合には、剥離紙３１により研磨材片の接着力を低減できるから、研磨材片に非再剥離型の粘着剤層を形成しても、研磨材片の再剥離、即ち研磨材片の張替えが容易になる。 FIG. 3 shows a nail clipping adhesive force adjusting means when the pressure-sensitive adhesive layer of the abrasive piece is non-removable.
FIG. 3A shows an example in which the adhesive force adjusting means 3 is provided on the blade body 23.
3B and 3C show an example in which an adhesive force adjusting means 3 made of release paper (release liner) is provided. A release paper 31 is attached to the blade body 23. In the release paper 31, a release agent layer 311 is formed on one surface of a substrate 312, an adhesive layer 313 is formed on the other surface, and the adhesive layer 313 is attached to the blade body 23. A non-removable adhesive is used for the adhesive layer 313. When the nail is polished, an abrasive piece is stuck on the release agent layer 311. FIG. 3B is an example in which a release agent layer is continuously formed, and FIG. 3C is an example in which the release agent layer is formed discontinuously. In the case of FIG.3 (c), the adhesive force of an abrasive | polishing material piece can be adjusted by changing the ratio of the part which formed the release agent layer, and the part which does not form.
In the case of FIGS. 3B and 3C, the adhesive force of the abrasive piece can be reduced by the release paper 31. Therefore, even if a non-removable adhesive layer is formed on the abrasive piece, the abrasive piece. Re-peeling, that is, replacement of the abrasive piece is facilitated.

図３（ｄ）は、剥離紙３１を爪切りに張付ける前の状態を示し、剥離紙３１の粘着剤層３１３に剥離紙（剥離ライナー）３２を張付けてある。剥離紙３２は、基材３２２、剥離剤層３２１からなる。
なお研磨材片の粘着剤層の粘着剤が再剥離型の場合には、爪切りに剥離紙３１を張付けることなく、爪切りに研磨材片を直接張付けることができる。したがって爪切りに剥離紙３１を張付けるか否かによって、非再剥離型粘着剤からなる粘着剤層を有する研磨材片と再剥離型粘着剤からなる粘着剤層を有する研磨材片の双方を同じ爪切りに使用することができる。
図３（ｅ），（ｆ）は、刃体２３に凹凸部３３からなる接着力調整手段３を設けた例である。
凹凸部３３には、凸条部２３１と凹部２３２を多数形成して、凸条部２３１と凹部２３２の比率を変えると、研磨材片の接着力を調整できる。凸条部２３１は、図３（ｅ），（ｆ）のものに限らず、鋸歯凸条部、円柱状又は円錐状の突起等でもよく、研磨材片の粘着剤層と接触する部分と非接触部分とが混在すればよい。 FIG. 3D shows a state before the release paper 31 is attached to the nail clipper, and the release paper (release liner) 32 is attached to the adhesive layer 313 of the release paper 31. The release paper 32 includes a base material 322 and a release agent layer 321.
When the adhesive of the adhesive layer of the abrasive piece is a re-peelable type, the abrasive piece can be directly attached to the nail clipper without attaching the release paper 31 to the nail clipper. Therefore, depending on whether or not the release paper 31 is attached to the nail clipper, both the abrasive piece having an adhesive layer made of a non-removable adhesive and the abrasive piece having an adhesive layer made of a removable adhesive are used. Can be used for the same nail clippers.
FIGS. 3E and 3F show an example in which the blade body 23 is provided with the adhesive force adjusting means 3 including the uneven portion 33.
By forming a large number of ridges 231 and recesses 232 in the concavo-convex part 33 and changing the ratio of the ridges 231 and the recesses 232, the adhesive strength of the abrasive strip can be adjusted. The protrusions 231 are not limited to those shown in FIGS. 3E and 3F, and may be sawtooth protrusions, columnar or conical protrusions, etc., and are not partly in contact with the adhesive layer of the abrasive piece. What is necessary is just to mix a contact part.
