Description
本発明は、粘着シート片積層体に関し、詳しくは所定の長さに裁断された粘着シート片を包装体、例えば箱体に収納して、一枚ずつ簡単に取り出すことができる粘着シート片に関する。 The present invention relates to a pressure-sensitive adhesive sheet laminate, and more particularly to a pressure-sensitive adhesive sheet piece that can be easily taken out one by one by storing the pressure-sensitive adhesive sheet pieces cut to a predetermined length in a package, for example, a box.
支持体の片面に粘着剤層が形成され、粘着剤層上にセパレータを被覆積層した粘着シートとしては、長尺の粘着シートを巻回してロール状にしたタイプや所定長さに裁断して片状にしたタイプがある。ロール状の粘着シートはコンパクトであるが、使用するに当ってはハサミなどで切断する必要があり、取扱性に問題がある。近年は手切れ性を付与したものも開発されているが、支持体に延伸処理やミシン目処理などの特定の処理を施す必要があり、製造面では均一な手切れ性を得るためには厳格な品質管理が必要となる。 As a pressure-sensitive adhesive sheet in which a pressure-sensitive adhesive layer is formed on one side of a support and a separator is coated and laminated on the pressure-sensitive adhesive layer, a long pressure-sensitive adhesive sheet is wound into a roll type or a predetermined length and cut. There is a shaped type. Although the roll-shaped adhesive sheet is compact, it needs to be cut with scissors or the like before use, and there is a problem in handleability. In recent years, products with hand cutting properties have been developed, but it is necessary to perform specific processing such as stretching and perforation processing on the support, and in terms of manufacturing it is strict to obtain uniform hand cutting properties. Quality control is required.
一方、所定長さの片状に裁断した場合には、上記のような問題はないが、複数枚のシート片を持ち運ぶ際に難点がある。しかも一枚一枚がバラバラであるので、たとえ包装体に収納したとしても取り出し性についても難点があるものである。 On the other hand, when the sheet is cut into pieces of a predetermined length, there is no problem as described above, but there is a difficulty in carrying a plurality of sheet pieces. Moreover, since each piece is disjoint, even if it is housed in a packaging body, there is a problem with respect to take-out properties.
このような問題点を解決するタイプとして、支持体、粘着剤層、およびセパレータを順次積層し、これを所定長さに裁断してなる粘着シート片を複数枚積重してなる積重体を得るに当って、粘着シート片の一端側のセパレータを一部除去して、下に位置する粘着シート片の支持体背面に粘着させる方法が提案されている。（特許文献１参照）。しかし、このタイプでは粘着シート片の粘着剤層が一部露出させて積重させなければならないので、製造上、容易でない。
本発明は従来にない新しいタイプの積層体（積重体）を提供することを目的とし、製造的にも比較的簡単で、しかも包装体に収納した場合の取り出し性などの取扱性に優れる粘着シート片積層体を提供することを目的としたものである。 The present invention aims to provide an unprecedented new type of laminate (stacked body), is relatively easy to manufacture, and has excellent handling properties such as removal when stored in a package. The object is to provide a single laminate.
本発明は、支持体、粘着剤層、およびセパレータを順次積層してなる粘着シート片が、二つ折りされて複数枚積層された粘着シート片積層体であって、上下の粘着シート片が所定幅の重ね代を介して重ね合わされ、上の粘着シート片が持ち上げられたときにその下に位置する粘着シート片が一緒に持ち上げられることを特徴とするものである。 The present invention is a pressure-sensitive adhesive sheet laminate in which a pressure-sensitive adhesive sheet piece formed by sequentially laminating a support, a pressure-sensitive adhesive layer, and a separator is folded in two and laminated, and the upper and lower pressure-sensitive adhesive sheet pieces have a predetermined width. When the upper pressure-sensitive adhesive sheet piece is lifted, the pressure-sensitive adhesive sheet piece located below the upper pressure-sensitive adhesive sheet sheet is lifted together.
本発明の粘着シート片積層体は、所定の長さに裁断された粘着シート片を複数枚積層してなるものであって、例えば箱体のような包装体に収納することによって、一枚ずつ簡単に取り出すことができるという効果を有するものであって、従来の粘着シート片積層体とは全く異なったタイプのものである。 The pressure-sensitive adhesive sheet piece laminate of the present invention is formed by laminating a plurality of pressure-sensitive adhesive sheet pieces cut to a predetermined length, for example, one by one by storing in a packaging body such as a box. It has an effect that it can be easily taken out, and is of a type completely different from the conventional adhesive sheet piece laminate.
図1は本発明の粘着シート片積層体を構成する粘着シート片を示す断面図である。即ち、本発明における粘着シート片は、支持体１の片面に粘着剤層２が形成され、さらに粘着剤層２の表面にセパレータ３が積層されている。また、本発明の粘着シート片積層体では上下に位置する粘着シート片を二つ折りして複数枚積層してなるものであるので、図１に示すように、セパレータ３には簡単に二つ折りするための、ミシン目または切れ目４を形成することが好ましい。 FIG. 1 is a cross-sectional view showing a pressure-sensitive adhesive sheet piece constituting the pressure-sensitive adhesive sheet piece laminate of the present invention. That is, in the pressure-sensitive adhesive sheet piece of the present invention, the pressure-sensitive adhesive layer 2 is formed on one surface of the support 1, and the separator 3 is laminated on the surface of the pressure-sensitive adhesive layer 2. Moreover, since the adhesive sheet piece laminated body of the present invention is formed by folding the adhesive sheet pieces positioned above and below and laminating a plurality of sheets, as shown in FIG. For this purpose, it is preferable to form a perforation or cut 4.
図２は、図１に示すような粘着シート片Ａを複数枚積層して本発明の粘着シート片積層体としたものを、包装体５に収納した状態を示す略式断面図である。包装体５の上方には取出し口６が設けられており、収納されている粘着シート片Ａを上方から１枚ずつ取り出すことができる。各粘着シート片は上下の粘着シート片が所定幅の重ね代を介して重ね合わされ、上の粘着シート片が持ち上げられたときにその下に位置する粘着シート片が一緒に持ち上げられるようになっているので、最上部に位置する粘着シート片Ａを１枚取り出すと、その下に位置する粘着シート片Ａの端部が取出し口６から外に突出して、取り出す際の把持部となるのである。 FIG. 2 is a schematic cross-sectional view showing a state in which a plurality of pressure-sensitive adhesive sheet pieces A as shown in FIG. A take-out port 6 is provided above the package 5 so that the stored adhesive sheet pieces A can be taken out one by one from above. Each pressure-sensitive adhesive sheet piece is overlapped with an upper and lower pressure-sensitive adhesive sheet piece over a predetermined width, and when the upper pressure-sensitive adhesive sheet piece is lifted, the lower pressure-sensitive adhesive sheet piece is lifted together. Therefore, when one piece of the adhesive sheet piece A located at the uppermost part is taken out, the end part of the adhesive sheet piece A located below protrudes out from the take-out port 6 and becomes a gripping part for taking out.
粘着シート片を構成する支持体は、後述する粘着剤層をその片面に投錨性良好に積層保持できるものである。具体的な材質としてはポリスチレン系の熱可塑性エラストマーフィルムや、ポリエチレン、ポリプロピレン、エチレン／メタクリル酸共重合体、エチレン／メタクリル酸メチルなどのポリオレフィン系フィルム、ポリエーテルポリウレタンやポリエステルポリウレタンなどのポリウレタン系フィルム、ポリエチレンテレフタレートなどのポリエステル系フィルム、ポリ塩化ビニルフィルム、ポリ塩化ビニリデンフィルム、各種プラスチック材料からなる織布や不織布、編布、紙、その他これらのフィルム同士の積層体、布帛や紙同士の積層体、フィルムと布帛との積層体、フィルムと金属箔との積層タイ、布帛や紙と金属箔との積層体などを用いることができる。 The support constituting the pressure-sensitive adhesive sheet piece is capable of laminating and holding a pressure-sensitive adhesive layer, which will be described later, on one side with good anchoring properties. Specific materials include polystyrene-based thermoplastic elastomer films, polyethylene, polypropylene, ethylene / methacrylic acid copolymers, polyolefin films such as ethylene / methyl methacrylate, polyurethane films such as polyether polyurethane and polyester polyurethane, Polyester films such as polyethylene terephthalate, polyvinyl chloride films, polyvinylidene chloride films, woven fabrics and nonwoven fabrics made of various plastic materials, knitted fabrics, paper, other laminates of these films, laminates of fabrics and papers, A laminate of film and fabric, a laminate tie of film and metal foil, a laminate of fabric or paper and metal foil, and the like can be used.
使用する支持体の厚みは材質によって任意であるが、自己支持性の点からは、通常、プラスチックフィルムを支持体とする場合には１５〜２５０μｍ、好ましくは２０〜１００μｍ程度とし、織布や不織布などの布帛や紙などを支持体とする場合には５０〜５００μｍ、好ましくは１００〜３００μｍ程度とする。なお、後者のように布帛や紙などを支持体材料に用いる場合は、絶対厚みを測定しにくいので、坪量が８〜２００ｇ／ｍ2程度のものを用いることが好適である。 The thickness of the support to be used is arbitrary depending on the material, but from the viewpoint of self-supporting property, when a plastic film is used as the support, it is usually 15 to 250 μm, preferably about 20 to 100 μm. In the case of using a fabric or paper as a support, the thickness is about 50 to 500 μm, preferably about 100 to 300 μm. In the latter case, when fabric or paper is used as the support material, it is difficult to measure the absolute thickness, and therefore it is preferable to use one having a basis weight of about 8 to 200 g / m 2 .
本発明において上記支持体の片面に積層される粘着剤層は、特に限定はなく、一般に使用される、アクリル系粘着剤、ゴム系粘着剤、シリコーン系粘着剤、ポリウレタン系粘着剤、ポリエステル系粘着剤など、従来公知の種々の粘着剤から形成することができる。 In the present invention, the pressure-sensitive adhesive layer laminated on one side of the support is not particularly limited, and is generally used as an acrylic pressure-sensitive adhesive, rubber-based pressure-sensitive adhesive, silicone-based pressure-sensitive adhesive, polyurethane-based pressure-sensitive adhesive, polyester-based pressure-sensitive adhesive. It can be formed from various conventionally known adhesives such as adhesives.
本発明における粘着シート片を皮膚に貼付して用いることを目的とするものとして実現する場合には、皮膚に複数回粘着可能であるとともに皮膚への刺激性が少ないという観点から、上記粘着剤の中でもアクリル系粘着剤を使用することが好ましく、特には、皮膚に対し貼付後もその部分の角質を剥離することが少なく、低皮膚刺激性を有するものであることから、特開平６−３１９７９３号公報に記載されたアクリル系粘着剤を使用することが特に好ましい。この特開平６−３１９７９３号公報に記載された粘着剤は、皮膚表面の凹凸に対し粘着剤が密着することによって皮膚への固定を維持させることから、皮膚ばかりでなく、新聞紙、紙などの層間破壊しやすい被着体に貼り付けて剥がしても、被着体を破壊することなく、きれいに剥がすことができるものである。 In the case where the adhesive sheet piece of the present invention is intended to be applied to the skin for use, it is possible to adhere to the skin a plurality of times and from the viewpoint of less irritation to the skin, Among them, it is preferable to use an acrylic pressure-sensitive adhesive, and in particular, it is less likely to peel off the keratin at the portion even after being applied to the skin and has low skin irritation. It is particularly preferable to use the acrylic pressure-sensitive adhesive described in the publication. The pressure-sensitive adhesive described in JP-A-6-319793 maintains the fixation to the skin when the pressure-sensitive adhesive is in close contact with the unevenness of the skin surface, so that not only the skin but also interlayers such as newspapers and papers are used. Even if affixed to an adherend that is easy to break and peeled off, the adherend can be removed cleanly without breaking the adherend.
また、粘着剤層の厚みは、５μｍ〜１５０μｍ、好ましくは１０μｍ〜８０μｍとする。粘着剤層の厚みが小さすぎると充分な粘着力が得られず、粘着剤層の厚みが大きすぎると、側面からの糊はみ出しが生じる恐れがあるので好ましくない。 The thickness of the pressure-sensitive adhesive layer is 5 μm to 150 μm, preferably 10 μm to 80 μm. If the thickness of the pressure-sensitive adhesive layer is too small, sufficient adhesive strength cannot be obtained, and if the thickness of the pressure-sensitive adhesive layer is too large, paste may protrude from the side surface, which is not preferable.
上記粘着剤層の表面を被覆保護するセパレータとしては、粘着剤層に接する側の表面に剥離処理を施したシートであればその材質に制限はなく、各種プラスチックシートや紙シートなどを用いることができる。剥離処理としては、自体公知の剥離処理剤、例えばフッ素樹脂やシリコーン樹脂などを塗布することで行うことができる。 The separator for covering and protecting the surface of the pressure-sensitive adhesive layer is not limited as long as it is a sheet subjected to a release treatment on the surface in contact with the pressure-sensitive adhesive layer, and various plastic sheets or paper sheets can be used. it can. The release treatment can be performed by applying a release agent known per se, such as a fluorine resin or a silicone resin.
本発明における包装体は硬質または軟質の材料から形成されるが、具体的にはプラスチック製の硬質または軟質容器や、各種プラスチックフィルム、紙、布帛などの包装シートで形成された袋体、紙箱などから形成される。そして、包装体の上面には収納している粘着シート片を取り出し可能な大きさの取出し口が形成されている。なお、持ち運び性、コンパクト性の点から、軟質な包装シートで形成された携帯用の包装体（包装袋）を用いることが好ましい。また前記取出し口は、開口しておればよいのでスリットであっても良いことは云うまでもない。 The packaging body in the present invention is formed of a hard or soft material, and specifically, a plastic hard or soft container, a bag body or a paper box formed of a packaging sheet such as various plastic films, paper, and fabric. Formed from. And the taking-out opening of the magnitude | size which can take out the accommodated adhesive sheet piece is formed in the upper surface of a package. From the viewpoint of portability and compactness, it is preferable to use a portable packaging body (packaging bag) formed of a soft packaging sheet. Needless to say, the outlet may be a slit as long as it is open.
