Abstract

<P>PROBLEM TO BE SOLVED: To provide an adhesive sheet in which a release sheet can easily be peeled off even when the release sheet to be discarded is only one sheet. <P>SOLUTION: In the adhesive sheet, an adhesive surface 10a is covered with one release sheet 20. In the release sheet 20, on an outer surface on the opposite side of an inner surface in contact with the adhesive surface, a different sheet material (rigidity imparting sheet material) 30 is laminated along the side and the rigidity of the lamination part is improved. Since a lamination area where the rigidity is improved can be pinched more easily than the other parts, the release sheet 20 is easily peeled off from the part. It is preferable to color the lamination area. Coloring becomes a mark and the part is further more easily pinched. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、粘着面に離型シートを備えてなる、救急絆創膏や外用貼付剤等の粘着シートに関する。   The present invention relates to a pressure-sensitive adhesive sheet such as an emergency bandage or an external patch comprising a release sheet on the pressure-sensitive adhesive surface.

上記粘着シートは、使用時に離型シートを引き剥がして粘着面を露出させ、これを患部に貼り付ける。その際、粘着面が単に１枚の離型シートで覆われていると捲り難いので、粘着面の中央でオーバーラップする２枚の離型シートを設けて、離型シートを捲り易く構成したものが知られている（特許文献１）。   The pressure-sensitive adhesive sheet peels off the release sheet during use to expose the pressure-sensitive adhesive surface, and affixes this to the affected area. At that time, if the adhesive surface is simply covered with a single release sheet, it is difficult to roll, so two release sheets that overlap at the center of the adhesive surface are provided to make the release sheet easy to roll Is known (Patent Document 1).

ところで、離型シートは粘着面から引き剥がされた後で廃棄されるものであるが、２枚の離型シートを備える粘着シートの場合、引き剥がした後では、別々に分離した２枚の離型シートが存在することとなるので、これを廃棄するのが面倒であったり、手間取ったりするといった問題がある。   By the way, the release sheet is discarded after being peeled off from the pressure-sensitive adhesive surface. However, in the case of the pressure-sensitive adhesive sheet having two release sheets, the two separated sheets are separated after being peeled off. Since the mold sheet is present, there is a problem that it is troublesome to dispose of the mold sheet, and it takes time and effort.

特開２００２−６５７２６号公報JP 2002-65726 A

上記従来の事情に鑑み、本発明の目的は、廃棄される離型シートが１枚のみであって、しかも、離型シートの剥離作業を行い易い粘着シートを提供することである。   In view of the above-described conventional circumstances, an object of the present invention is to provide a pressure-sensitive adhesive sheet in which only one release sheet is discarded and the release sheet can be easily peeled off.

本発明は、上記要望に応えるべく創案されたものであって、以下の特徴を備えた粘着シートを提供するものである。
すなわち、本発明の粘着シートは、粘着面を１枚の離型シートで覆ってなる。離型シートは、粘着面に接する内表面とは反対側の外表面において、その側辺に沿って、別のシート材（剛性付与シート材）が積層されて当該積層部分の剛性が高められている。 The present invention has been developed to meet the above-described demand, and provides an adhesive sheet having the following characteristics.
That is, the pressure-sensitive adhesive sheet of the present invention is obtained by covering the pressure-sensitive adhesive surface with a single release sheet. In the release sheet, another sheet material (stiffening sheet material) is laminated on the outer surface opposite to the inner surface in contact with the adhesive surface, and the rigidity of the laminated portion is increased. Yes.

本発明の粘着シートにおいては、粘着面を覆う離型シートが１枚のみであるため、当該離型シートを捲り取った後における廃棄作業が簡単となる。
一方、離型シートは、粘着面に接する内表面とは反対側の外表面において、その側辺に沿って、別のシート材が積層されて当該積層部分の剛性が高められている。つまり、剛性の高められた部分は、そうでない部分に比べて摘み上げ易く、しかもそのように剛性の高められた領域が離型シートの側辺に沿って存在しているので、使用者は、この部分を摘んで、簡単に離型シートを捲り取ることができる。 In the pressure-sensitive adhesive sheet of the present invention, since there is only one release sheet covering the pressure-sensitive adhesive surface, disposal work after scraping off the release sheet is simplified.
On the other hand, in the release sheet, on the outer surface opposite to the inner surface in contact with the adhesive surface, another sheet material is laminated along the side to increase the rigidity of the laminated portion. In other words, the portion with increased rigidity is easier to pick up than the portion with no rigidity, and the region with increased rigidity exists along the side of the release sheet. This part can be picked and the release sheet can be easily scraped off.

なお、積層により剛性を高めた部分には、着色を施すことが好ましい。着色が目印となって、より簡単にこの部分を摘んで、離型シートを捲り取ることができる。   In addition, it is preferable to color the part which raised rigidity by lamination. Coloring serves as a mark, and this part can be easily picked and the release sheet can be scraped off.

本発明の実施形態を、添付の図面を参照して、以下に詳細に説明する。図１は、本発明の一実施形態に係る粘着シート１０を真上から見た平面図である。図２は、積層部分を摘んで、離型シート２０を捲り取っている状態を示す斜視図である。   Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a plan view of an adhesive sheet 10 according to an embodiment of the present invention as viewed from directly above. FIG. 2 is a perspective view showing a state in which the release sheet 20 is scraped off by picking up the laminated portion.

粘着シート１０は、その片面が薬剤等を含有する粘着面１０ａとされている。本発明においては、この粘着面１０ａを１枚のフィルム状の離型シート２０で覆っている。離型シート２０が１枚のみであるから、これを捲り取った後での廃棄が簡単かつ便利なものとなる。   The pressure-sensitive adhesive sheet 10 has a single-sided adhesive surface 10a containing a drug or the like. In the present invention, the adhesive surface 10a is covered with a single film-like release sheet 20. Since there is only one release sheet 20, disposal after scraping it becomes simple and convenient.

粘着シート１０は、直交する第１辺１１および第２辺１２を含む矩形形状をなしている。また、離型シート２０は、粘着シート１０とほぼ同一の外形を有していて、直交する第１辺２１および第２辺２２を含む矩形形状である。したがって、図１においては、粘着シート１０の第１辺１１、第２辺１２は、それぞれ、離型シート２０の第１辺２１、第２辺２２と重なって現れる。   The pressure-sensitive adhesive sheet 10 has a rectangular shape including a first side 11 and a second side 12 that are orthogonal to each other. Moreover, the release sheet 20 has substantially the same outer shape as the pressure-sensitive adhesive sheet 10 and has a rectangular shape including a first side 21 and a second side 22 that are orthogonal to each other. Therefore, in FIG. 1, the first side 11 and the second side 12 of the pressure-sensitive adhesive sheet 10 appear to overlap the first side 21 and the second side 22 of the release sheet 20, respectively.

≪離型シートの剛性を高めるための剛性付与シート材≫
図３は、図１に示した粘着シート１０の側面図であり、図４は、その積層構成を示す分解斜視図である。
図３および図４に示したように、離型シート２０には、粘着面１０ａに接する内表面とは反対側の外表面上に別のシート材３０が積層されている。このシート材３０は離型シート２０の剛性を部分的に高めるために積層されるものであり、したがって、以下このシート材を剛性付与シート材３０と呼ぶ。 ≪Stiffening sheet material to increase the rigidity of the release sheet≫
FIG. 3 is a side view of the pressure-sensitive adhesive sheet 10 shown in FIG. 1, and FIG. 4 is an exploded perspective view showing the laminated structure.
As shown in FIGS. 3 and 4, another sheet material 30 is laminated on the release sheet 20 on the outer surface opposite to the inner surface in contact with the adhesive surface 10 a. This sheet material 30 is laminated in order to partially increase the rigidity of the release sheet 20. Therefore, this sheet material is hereinafter referred to as a rigidity imparted sheet material 30.

剛性付与シート材３０が積層された離型シート２０上の領域は、それ以外の部分よりも剛性が高くなる。しかも、そのように剛性の高められた領域が離型シート２０の側辺に沿って存在しているので、この部分を簡単に摘み上げることができる。したがって、離型シート２０は、この部分から簡単に引き剥がすことができる。   The region on the release sheet 20 on which the stiffness imparting sheet material 30 is laminated has higher rigidity than the other portions. And since the area | region where the rigidity was increased in that way exists along the side of the release sheet 20, this part can be picked up easily. Therefore, the release sheet 20 can be easily peeled off from this portion.

なお、粘着シートおよび薬剤等は一般的に知られたものであり、離型シート２０についても、それ自体は、ポリプロピレン等の材料から製造される一般的なものである。
また、剛性付与シート材３０については、これを積層することによって離型シート２０の剛性を高めることのできる材料であれば足り、特定のものには限定されない。離型シート２０と同じ材料を用いることも勿論可能である。 In addition, the adhesive sheet, the medicine, and the like are generally known, and the release sheet 20 is also generally manufactured from a material such as polypropylene.
Moreover, about the rigidity provision sheet | seat material 30, as long as it is a material which can raise the rigidity of the release sheet 20 by laminating this, it is sufficient and it is not limited to a specific thing. Of course, it is possible to use the same material as that of the release sheet 20.

≪粘着シートの形状≫
図示した粘着シート１０は、直交する２辺１１、１２を含む矩形形状としているが、本発明においては、粘着シート１０の形状は、矩形以外にも、円形、楕円形、多角形、その他任意のものを採用できる。ただ、矩形形状の粘着シート１０は、製造ラインにおいて大量生産するのに適した形状である。
粘着シートおよび離型シートが矩形以外の形状をなしている場合においても、離型シート上の側辺に沿って剛性付与シート材を積層して剛性が高めれば、図示した実施形態と同様に、その部分を摘んで簡単に離型シートを捲り取ることができる。 ≪Adhesive sheet shape≫
The illustrated pressure-sensitive adhesive sheet 10 has a rectangular shape including two sides 11 and 12 that are orthogonal to each other. However, in the present invention, the shape of the pressure-sensitive adhesive sheet 10 is not limited to a rectangle, but may be a circle, an ellipse, a polygon, or any other shape. You can adopt things. However, the rectangular pressure-sensitive adhesive sheet 10 has a shape suitable for mass production in a production line.
Even when the pressure-sensitive adhesive sheet and the release sheet have a shape other than a rectangle, if the rigidity is increased by laminating the rigidity-imparting sheet material along the side edges on the release sheet, similarly to the illustrated embodiment, The release sheet can be scraped off easily by picking that part.

≪着色≫
なお、剛性付与シート材３０を積層した部分には、例えばピンク色等の適当な着色を施すことが好ましい。着色が目印となって、使用者は、さらに簡単にその部分を摘み上げることができる。 ≪Coloring≫
In addition, it is preferable to give suitable coloring, such as a pink color, to the part which laminated | stacked the rigidity provision sheet material 30, for example. The coloring becomes a mark, and the user can pick up the portion more easily.

積層領域に着色を施す場合、剛性付与シート材３０に着色を施すことも勿論可能であるが、剛性付与シート材３０を透明として、その下方側に位置する離型シート２０上に着色することが好ましい。その理由は、次の通りである。
離型シート２０には、通常何らかの印刷（使用方法や薬効成分等）が施されるので、積層領域における着色も含めて、すべての印刷を離型シート２０上に集中させることができる。すなわち、離型シート２０およびシート材３０の両方に印刷を施す必要がなくなり、離型シート２０のみに印刷を行うだけで足りるので、製造工程が簡略化できる。 When coloring the laminated region, it is of course possible to color the rigidity-imparting sheet material 30, but the rigidity-imparting sheet material 30 may be transparent and colored on the release sheet 20 located on the lower side thereof. preferable. The reason is as follows.
Since the release sheet 20 is usually subjected to some kind of printing (usage method, medicinal component, etc.), all the printing including the coloring in the laminated region can be concentrated on the release sheet 20. That is, it is not necessary to print on both the release sheet 20 and the sheet material 30, and it is sufficient to print only on the release sheet 20, so that the manufacturing process can be simplified.
