Description
本発明は、皮膚貼付用粘着シートに関し、詳しくは、スポーツ用テーピングや治療用テーピングなどに用いる皮膚貼付用粘着シート、または絆創膏や粘着包帯等の医療用途に用いることができる皮膚貼付用粘着シートに関するものである。 The present invention relates to an adhesive sheet for skin application, and more particularly to an adhesive sheet for skin application used for sports taping, therapeutic taping, etc., or an adhesive sheet for skin application that can be used for medical applications such as adhesive bandages and adhesive bandages. Is.
従来、いわゆるスポーツ用テーピングや治療用テーピングに用いられる粘着テープや、医療用に用いられる粘着テープは、ロール状に巻回された粘着テープを皮膚面に適度な張力をかけながら貼り付けることによって、対象部位の怪我の予防や治療などに様々な効果を期待するものである（例えば、非特許文献１参照）。 Conventionally, adhesive tapes used for so-called sports taping and treatment taping, and adhesive tapes used for medical purposes are applied by applying an adhesive tape wound in a roll shape while applying an appropriate tension to the skin surface. Various effects are expected for the prevention and treatment of injuries at the target site (for example, see Non-Patent Document 1).
また、この種の皮膚貼付用の粘着テープは、一般的には支持基材の一方の面に粘着剤層が設けられ、さらに粘着剤層の表面を被覆するようにセパレータ（剥離紙）が貼り合わせた構成からなるものである。そして、使用時には皮膚貼付用粘着テープにおけるセパレータを剥がし、露出した粘着剤層を皮膚の貼付対象位置に貼り付けるものである。 Also, this type of adhesive tape for skin application is generally provided with an adhesive layer on one side of a support substrate, and a separator (release paper) is applied to cover the surface of the adhesive layer. It consists of a combined configuration. In use, the separator in the adhesive tape for skin application is peeled off, and the exposed adhesive layer is applied to the application target position on the skin.
しかしながら、このようなロール状の皮膚貼付用粘着テープは、使用する際にはハサミなどを用いて貼付部位に合わせた長さに裁断する必要があるが、裁断時にハサミの刃の部分に粘着剤が付着して綺麗に裁断できないという問題がある。さらに、所定長さに裁断した粘着テープを皮膚面に貼付するには、セパレータを剥離しなければならないが、セパレータを全て剥離してしまうと、貼付時に粘着剤層面同士がひっついて綺麗に皮膚面に貼付できないという問題もある。そこで、セパレータを端部から徐々に剥離しながら皮膚面に粘着テープを貼付する方法もあるが、粘着テープに適度な張力をかけて貼付するには適度な技術を要するという問題があった。 However, such a roll-shaped adhesive tape for skin application needs to be cut to a length suitable for the application site using scissors or the like when used, but the adhesive is applied to the scissors blade part at the time of cutting. There is a problem that it cannot be cut cleanly due to adhesion. Furthermore, in order to apply the adhesive tape cut to a predetermined length to the skin surface, the separator must be peeled off. However, if all the separators are peeled off, the adhesive layer surfaces will stick together at the time of application and the skin surface will be clean. There is also a problem that it can not be attached to. Therefore, there is a method of applying an adhesive tape to the skin surface while gradually peeling the separator from the end, but there is a problem that an appropriate technique is required to apply an appropriate tension to the adhesive tape.
一方、絆創膏等の医療用テープにおいてもロール状の巻き絆創膏が一般に使用されているが、やはり使用時には任意の長さに切断する必要があり、上述した問題がある。巻き絆創膏の場合は、上述したように張力をかけて貼付するということはないが、手で引きちぎる手間を省き、また粘着面に指が触れることがないようにするために、予め所定長さに裁断された医療用テープが提案されている（例えば、特許文献１参照）。 On the other hand, roll-shaped wound bandages are generally used also for medical tapes such as bandages, but it is necessary to cut them to an arbitrary length at the time of use. In the case of wound bandages, there is no need to apply tension as described above, but in order to save the trouble of tearing by hand and to prevent the finger from touching the adhesive surface, the length should be set in advance. A cut medical tape has been proposed (see, for example, Patent Document 1).
上述したように、従来のロール状に巻回された粘着テープの場合は、使用するに際してハサミなどで裁断する必要があるので、何枚も切断する場合は非常に手間がかかるという問題があると共に、裁断長さがまちまちとなり、一定長さに裁断しがたいという問題があった。また、特許文献１に記載のような予め所定長さに裁断し、各テープ片を切り離すためのミシン目を設けた粘着シートの場合は、所定長さの医療用テープとして使用できるが、セパレータを剥離して使用する場合は、前記したような粘着面同士が付着したり、伸縮性支持基材を採用した場合には一定の張力をかけて貼付しがたいという問題があった。 As described above, in the case of an adhesive tape wound in a conventional roll shape, it is necessary to cut with scissors or the like when using it, so there is a problem that it takes a lot of work when cutting a number of sheets. The cutting length varies, and there is a problem that it is difficult to cut to a certain length. In addition, in the case of an adhesive sheet that is preliminarily cut to a predetermined length as described in Patent Document 1 and provided with a perforation for separating each tape piece, it can be used as a medical tape of a predetermined length. When peeling and using, there existed a problem that it was hard to stick by applying fixed tension, when the above adhesive surfaces adhered, or when an elastic support base material was employ | adopted.
そこで、本発明は、伸縮性支持基材の片面に粘着剤層およびセパレータが順次積層されてなる皮膚貼付用粘着シートにおいて、所定長さの粘着シートを切り出すことができ、しかもセパレータを剥離して使用するに際して、粘着シートへの適度な張力をかけながら綺麗に皮膚面に貼付することができる皮膚貼付用粘着シートを提供することを課題とする。 Accordingly, the present invention provides a skin adhesive pressure-sensitive adhesive sheet in which a pressure-sensitive adhesive layer and a separator are sequentially laminated on one side of a stretchable support base material, and a pressure-sensitive adhesive sheet having a predetermined length can be cut out. It is an object of the present invention to provide a pressure-sensitive adhesive sheet for skin application that can be applied to the skin surface cleanly while applying an appropriate tension to the pressure-sensitive adhesive sheet.
本発明は上記の課題を解決するために鋭意検討した結果、見い出されたものであり、伸縮性支持基材の片面に粘着剤層が形成され、該粘着剤層の表面に幅方向にわたって複数のミシン目が設けられたセパレータにて被覆保護され、短冊状シートに加工された皮膚貼付用粘着シートであって、複数枚の各皮膚貼付用粘着シートが長さ方向の端縁部を合わせるように接合されていることを特徴とするものである。 The present invention has been found as a result of intensive studies to solve the above-mentioned problems, and a pressure-sensitive adhesive layer is formed on one surface of the stretchable support base material, and a plurality of pressure-sensitive adhesive layers are formed across the width direction on the surface of the pressure-sensitive adhesive layer. It is a pressure-sensitive adhesive sheet for skin application that is covered and protected by a separator provided with perforations, and is processed into a strip-shaped sheet so that each of the plurality of pressure-sensitive adhesive sheets for skin application is aligned with the edge in the length direction. It is characterized by being joined.
特に、長さ方向の端縁部が接合された複数枚の皮膚貼付用粘着シートが、端縁部で折り畳まれて袋内に収納されている状態にすることによって、コンパクトに収納することができて携帯にも便利である。 In particular, a plurality of adhesive sheets for skin application to which the edge portions in the lengthwise direction are joined can be stored in a compact manner by being folded at the edge portions and stored in a bag. It is convenient to carry.
本発明の皮膚貼付用粘着シートは、伸縮性支持基材の片面に設けられた粘着剤層の表面に被覆されているセパレータの幅方向にわたって複数のミシン目を設けているので、粘着シートのセパレータを端部から全部剥がすのではなく、端部や中央部のセパレータのみを一部剥離除去することによって粘着剤層を露出させ、露出した粘着剤層を皮膚面に貼付した後、残部のセパレータを剥離しながら貼付操作を行なうことができるので、粘着剤層面同士がひっつくことがなく綺麗に貼付することができるという効果を奏するものである。特に、テーピング用途の粘着シートの場合は、粘着シートの一部を貼付した後、適度な張力をかけながら貼付することによって、簡単に有効なテーピング操作ができるものである。 Since the adhesive sheet for skin application of the present invention is provided with a plurality of perforations across the width direction of the separator coated on the surface of the adhesive layer provided on one side of the stretchable support substrate, the separator of the adhesive sheet The adhesive layer is exposed by peeling and removing only the separator at the end and the center part, and the remaining separator is attached to the skin surface. Since the sticking operation can be performed while peeling, the adhesive layer surfaces do not stick to each other, and the sticking can be performed neatly. In particular, in the case of a pressure-sensitive adhesive sheet for taping, an effective taping operation can be easily performed by pasting a part of the pressure-sensitive adhesive sheet and applying it while applying an appropriate tension.
また、本発明の皮膚貼付用粘着シートは、ロール状に巻回したものではなく、所定の長さの短冊状シートに裁断したものであるが、各シートは１枚ずつバラバラになっているのではなく、長さ方向の端縁部を合わせるように接合されているので、折り畳んで袋内に収納できると共に、使用時にはシート端縁部の接合箇所で簡単に切り離して使用することができ、携帯等にも便利な形状である。 Further, the adhesive sheet for skin application of the present invention is not wound in a roll shape, but is cut into a strip-shaped sheet of a predetermined length, but each sheet is separated one by one. Rather than being joined so that the edge in the length direction is aligned, it can be folded and stored in the bag, and can be easily separated and used at the joint at the edge of the sheet when in use. It is also a convenient shape for such as.
本発明の皮膚貼付用粘着シートは、伸縮性支持基材の片面に粘着剤層が形成され、該粘着剤層の表面に幅方向にわたって複数のミシン目を有するセパレータにて被覆保護された短冊状のシートである。本発明では所定の長さおよび幅の短冊状のシートに加工しておくことで、使用する際にハサミなどで裁断する必要がなく、非常に便利であり、特にスポーツテーピングやテーピング治療（リハビリテーピング）、医療包帯用などの種々の目的に使用することができるものである。 The pressure-sensitive adhesive sheet for skin application of the present invention has a strip-like shape in which a pressure-sensitive adhesive layer is formed on one side of a stretchable support substrate, and the surface of the pressure-sensitive adhesive layer is covered and protected with a separator having a plurality of perforations across the width direction. This is a sheet. In the present invention, by processing into a strip-like sheet of a predetermined length and width, there is no need to cut with scissors when using it, and it is very convenient, especially sports taping and taping treatment (rehabilitation taping) ), And can be used for various purposes such as medical bandages.
本発明において用いられる伸縮性支持基材としては、皮膚面に貼付使用した際に皮膚の動きに合わせて適度に伸縮するものであれば、その材質は特に限定されないが、例えば、ポリエチレン、ポリプロピレン、ポリブテン、エチレン−プロピレン共重合体、エチレン−酢酸ビニル共重合体、エチレン−エチルアクリレート共重合体などの各種ポリオレフィン類、あるいはポリウレタン、ポリアミド、ポリエステルなどを用いることができる。これらの支持基材の材質のうち、ポリオレフィンやポリオレフィンなどは、適度な伸縮性と機械的強度の点から好ましいものである。なお、これらの支持基材は平滑なフィルムや発泡シート、不織布、織布、編布、これらの積層体などとして使用に供することができ、伸縮性および貼付時の肌触りの点から好ましくは不織布を用いることがよい。また、本発明の伸縮性支持基材は所定ピッチで穿孔処理を施すことによって、通気性等を向上させることも可能である。 The stretchable support substrate used in the present invention is not particularly limited as long as it stretches appropriately in accordance with the movement of the skin when applied to the skin surface. For example, polyethylene, polypropylene, Various polyolefins such as polybutene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, polyurethane, polyamide, polyester, and the like can be used. Of these support base materials, polyolefin, polyolefin, and the like are preferable in terms of moderate stretchability and mechanical strength. These supporting substrates can be used as smooth films, foamed sheets, nonwoven fabrics, woven fabrics, knitted fabrics, laminates thereof, etc., and preferably non-woven fabrics from the viewpoint of stretchability and touch when applied. It is good to use. In addition, the stretchable support substrate of the present invention can be improved in breathability and the like by performing perforation treatment at a predetermined pitch.
本発明の皮膚貼付用粘着シートにおいて、上記伸縮性支持基材の片面に形成される粘着剤層は、医療用粘着剤として自体公知の粘着剤から形成することができ、具体的にはアクリル系粘着剤やゴム系粘着剤、シリコーン系粘着剤、ビニルエーテル系粘着剤などをそのまま、もしくは混合して用いることができる。さらに粘着剤層には粘着剤と相溶性の良好な有機液状成分を含有させたり、粘着付与剤や軟化剤などを配合することもできる。有機液状成分を含有させた場合には、粘着剤層の内部凝集力が不足する恐れがあるので、その場合は、架橋剤による架橋処理を行ない、内部凝集力を補うことが好ましい。 In the pressure-sensitive adhesive sheet for skin application of the present invention, the pressure-sensitive adhesive layer formed on one side of the stretchable support substrate can be formed from a pressure-sensitive adhesive known per se as a medical pressure-sensitive adhesive, specifically an acrylic type A pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, a silicone-based pressure-sensitive adhesive, a vinyl ether-based pressure-sensitive adhesive, or the like can be used as it is or in combination. Further, the pressure-sensitive adhesive layer can contain an organic liquid component having good compatibility with the pressure-sensitive adhesive, or a tackifier, a softening agent, or the like can be blended. When the organic liquid component is contained, the internal cohesive force of the pressure-sensitive adhesive layer may be insufficient. In this case, it is preferable to compensate for the internal cohesive force by performing a crosslinking treatment with a crosslinking agent.
粘着剤層は上記伸縮性支持基材の片面全面に形成することできるが、伸縮性支持基材が透湿性の高い支持基材の場合は、支持基材の透湿性を阻害しないように、部分的に粘着剤層を形成する、所謂パターン状に形成することが好ましい。粘着剤層をパターン状に形成する場合は、直線状や波状、鋸歯状、点状など各種パターンで形成することができるが、形成しやすさや短冊状の粘着シートの長さ方向や幅方向の皮膚接着性の低下をできるだけ防ぐためにはサインカーブ状や、疑似サインカーブ状、三角波、円弧波状などの波状に形成することが好ましい。 The pressure-sensitive adhesive layer can be formed on the entire surface of one side of the above-mentioned stretchable support substrate, but if the stretchable support substrate is a highly moisture-permeable support substrate, it is necessary not to disturb the moisture permeability of the support substrate. It is preferable to form a pressure-sensitive adhesive layer in a so-called pattern. When forming the pressure-sensitive adhesive layer in a pattern, it can be formed in various patterns such as linear, wavy, sawtooth, and dot-like, but it is easy to form and in the length direction and width direction of the strip-shaped pressure-sensitive adhesive sheet In order to prevent deterioration of skin adhesiveness as much as possible, it is preferably formed in a wave shape such as a sine curve shape, a pseudo sine curve shape, a triangular wave, or an arc wave shape.
上記粘着剤層の表面に積層して、粘着剤層表面を被覆保護するセパレータとしては、片面もしくは両面がシリコーン樹脂やフッ素樹脂の他、ポリマー鎖に長鎖アルキル基を結合した長鎖アルキル系離型剤などで離型処理されている基材、もしくは基材自体が離型能を有するセパレータを用いることができる。離型処理する基材としては、各種プラスチックフィルムや紙基材なども用いることができるが、セパレータに設けられたミシン目や破断線によってセパレータの一部を裁断する際に、小さな力で簡単に裁断できるという点からは、パルプ繊維などからなる紙製のセパレータを用いることが好ましい。 As a separator that is laminated on the surface of the pressure-sensitive adhesive layer to cover and protect the surface of the pressure-sensitive adhesive layer, a long-chain alkyl group having a long-chain alkyl group bonded to a polymer chain in addition to a silicone resin or fluororesin on one or both sides. A base material that has been subjected to a release treatment with a mold agent or the like, or a separator having a release ability of the base material itself can be used. Various plastic films, paper bases, etc. can be used as the base material for mold release treatment, but when a part of the separator is cut with a perforation or break line provided in the separator, it can be easily performed with a small force. In view of being able to cut, it is preferable to use a paper separator made of pulp fiber or the like.
本発明においては、上記セパレータには幅方向にわたって複数のミシン目が形成されていることを特徴としている。また、ミシン目はセパレータを所定幅に裁断できるように、一定間隔で設けられていることが好ましく、貼付操作性の点からは、１０〜５０ｍｍ、好ましくは１５〜３０ｍｍ程度の間隔で設けることが好ましい。本発明の皮膚貼付用粘着シートを皮膚面に貼付使用する場合は、セパレータの一部をミシン目に沿って裁断除去し、露出した粘着剤層を一旦皮膚面に貼付固定した後、残存するセパレータを剥離しながら粘着シートを貼付する。このように貼付することによって、露出した粘着面同士がひっついて綺麗に貼付することができないという不具合を解消できると共に、テーピング用途などでは所望の張力をかけながら貼付することができるのである。 In the present invention, the separator has a plurality of perforations formed in the width direction. Further, the perforations are preferably provided at regular intervals so that the separator can be cut into a predetermined width. From the viewpoint of sticking operability, the perforations are provided at intervals of about 10 to 50 mm, preferably about 15 to 30 mm. preferable. When the adhesive sheet for skin application of the present invention is applied to the skin surface, a part of the separator is cut and removed along the perforation, and the exposed adhesive layer is once adhered and fixed to the skin surface, and then the remaining separator. Affix the adhesive sheet while peeling off. By sticking in this way, it is possible to solve the problem that the exposed adhesive surfaces are stuck together and cannot be applied neatly, and can be applied while applying a desired tension in taping applications and the like.
さらに、本発明の皮膚貼付用粘着シートは、取り扱い性を向上させるという点から、ロール状に巻回されたものでなく、予め所定の長さに裁断された短冊状のシートであることを特徴としている。具体的には幅２５〜７５ｍｍ、長さ１００〜２００ｍｍ、好ましくは幅３８〜５０ｍｍ、長さ１２０〜１８０ｍｍの大きさに裁断しておくことが、腕や足、肘や膝、肩、手首、足首などの関節部に貼付する場合に最適な大きさなのである。 Furthermore, the pressure-sensitive adhesive sheet for skin application of the present invention is not a sheet wound in a roll shape but a strip-shaped sheet cut in advance to a predetermined length from the viewpoint of improving the handleability. It is said. Specifically, cutting to a size of 25 to 75 mm in width and 100 to 200 mm in length, preferably 38 to 50 mm in width and 120 to 180 mm in length, arms and legs, elbows and knees, shoulders, wrists, It is the optimal size when affixed to joints such as ankles.
本発明の皮膚貼付用粘着シートは、図１や図２に示すように、上記構成からなる短冊状に加工された複数枚の粘着シートを、長さ方向の端縁部を合わせるように接合されたものであり、各皮膚貼付用粘着シートにはセパレータ３が６分割されるように５本のミシン目４が設けられている。また、図１や図２に示すように、４枚の粘着シートが破断線５によって接合されていることが好ましい。 As shown in FIG. 1 and FIG. 2, the adhesive sheet for skin application of the present invention is formed by joining a plurality of adhesive sheets processed into a strip shape having the above-described configuration so that the edge portions in the length direction are aligned. Each skin adhesive sheet is provided with five perforations 4 so that the separator 3 is divided into six parts. Moreover, as shown in FIG. 1 and FIG. 2, it is preferable that four adhesive sheets are joined together by a break line 5.
破断線は短冊状の各粘着シートを長さ方向の端縁部（長辺部）に沿って設けられており、破断線にて裁断することによって各粘着シートを取り出すようになっている。この破断線はセパレータのみに形成されており、伸縮性支持基材および粘着剤層は各粘着シート単位で分離されている。つまり、図３（ａ）に示されているように、セパレータ３に設けられている破断線で各粘着シートが繋がった状態なのである。本発明における破断線における接合部分、つまりセパレータが繋がっている部分の長さは、０．１〜１ｍｍ、好ましくは０．２〜０．５ｍｍの範囲に設定することで、簡単に手で破断させることができる。また、破断線における切断部分は、３〜２０ｍｍ、好ましくは５〜１５ｍｍに設定することで各粘着シートを綺麗に切り取ることができるものである。 The break line is provided for each strip-like pressure-sensitive adhesive sheet along the end edge (long side) in the length direction, and each pressure-sensitive adhesive sheet is taken out by cutting along the break line. This break line is formed only in the separator, and the stretchable support substrate and the pressure-sensitive adhesive layer are separated for each pressure-sensitive adhesive sheet. That is, as shown in FIG. 3A, each adhesive sheet is connected by a break line provided in the separator 3. In the present invention, the length of the joining portion in the breaking line, that is, the portion where the separator is connected is set to a range of 0.1 to 1 mm, preferably 0.2 to 0.5 mm, so that it is easily broken by hand. be able to. Moreover, the cutting part in a fracture | rupture line can cut off each adhesive sheet beautifully by setting to 3-20 mm, Preferably it is 5-15 mm.
本発明の皮膚貼付用粘着シートは、上記の構成からなるものであるが、保管時および携帯容易性の面からは、図３（ａ）に示すように折り畳むことによって、図３（ｂ）に示すような状態にすることができ、これを袋内に収納することでコンパクト化できるものである。なお、図３（ｂ）のような折り畳んだ状態にした際に、セパレータが最外層になるようにすることで、袋内に収納した場合、袋内面とセパレータが接するような位置関係になるので、袋内へ滑り性よく収納できると共に、取り出す際にも内面にひっかからずに取り出すことができて好ましいものである。 The pressure-sensitive adhesive sheet for skin application of the present invention has the above-described configuration. From the viewpoint of storage and portability, the adhesive sheet is folded as shown in FIG. It can be in the state shown, and can be made compact by storing it in a bag.
