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 it 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 a 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、粘着シートの側辺に沿う領域部分が折り畳まれていて、当該折り畳まれた領域部分は、「上記側辺から離れる方向へと離型シート上に折り畳まれた第１折畳部」と「上記側辺に向かう方向へと第１折畳部上に折り畳まれた第２折畳部」とを含んでいる。 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, the region portion along the side of the pressure-sensitive adhesive sheet is folded, and the folded region portion is “the first folding portion folded on the release sheet in a direction away from the side. And “a second folded portion folded on the first folded portion in the direction toward the side”.

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、離型シートの上記折り畳まれた領域部分においては、第１折畳部および第２折畳部が粘着シートの粘着面からフリーな状態（粘着されていない）となっているので、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 folded region portion of the release sheet, the first and second folding parts are free from the adhesive surface of the adhesive sheet (not adhered), so that the user Can pick up this part and scrape off the release sheet easily.

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、折畳領域部を摘んで、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 gripping the folding area.

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, it is easy and convenient to discard the sheet after scraping it.

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。   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.

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。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、粘着シート１０の第１辺１１に沿う領域が折り畳まれている。この折畳領域部は、使用者がここを摘んで離型シート２０を簡単に捲り取ることができるよう、設けられたものである。   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. The release sheet 20 has substantially the same outer shape as the pressure-sensitive adhesive sheet 10, and a region along the first side 11 of the pressure-sensitive adhesive sheet 10 is folded. This folding region portion is provided so that the user can easily pick up the release sheet 20 by picking it up.

図３は、図１の粘着シートの側面図であって、離型シート２０の片側に設けた折畳領域部における折畳み構造を部分的に拡大して示している。図３中において、楕円枠Ａ内に示した部分拡大図は、図１および図２に示した粘着シート１０に対応している。
楕円枠Ｂ内には、別の実施形態を示している。 FIG. 3 is a side view of the pressure-sensitive adhesive sheet of FIG. 1 and partially shows a folding structure in a folding region provided on one side of the release sheet 20. In FIG. 3, the partially enlarged view shown in the ellipse frame A corresponds to the adhesive sheet 10 shown in FIGS.
In the oval frame B, another embodiment is shown.

≪楕円枠Ａ内に示した実施形態≫
第１折畳部２５は、折畳線２５ａに沿って、粘着シートの第１辺１１から離れる方向へと離型シート２０上に折り畳まれている。反対に、第２折畳部２６は、折畳線２５ｂに沿って、第１辺１１に向かう方向へと第１折畳部２５上に折り畳まれている。
すなわち、離型シート２０およびその端部に設けた折畳領域部は、全体が１枚のシート材で構成されていて、折畳線２５ａと２５ｂとの間に挟まれた領域が第１折畳部２５で、これに折畳線２５ｂを介して第２折畳部２６が連設された構成となっている。 << Embodiment shown in ellipse frame A >>
The first folding unit 25 is folded on the release sheet 20 in a direction away from the first side 11 of the adhesive sheet along the folding line 25a. On the other hand, the second folding part 26 is folded on the first folding part 25 in the direction toward the first side 11 along the folding line 25b.
That is, the release sheet 20 and the folding region portion provided at the end thereof are entirely composed of one sheet material, and the region sandwiched between the folding lines 25a and 25b is the first folding. In the tatami unit 25, the second fold unit 26 is connected to the tatami unit 25 via a fold line 25b.

第１折畳部２５および第２折畳部２６は、いずれも、粘着シート１０の粘着面に対してフリーな状態（粘着されていない）にあるので、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捲り取ることができる。   Since both the first folding part 25 and the second folding part 26 are in a free state (not adhered) to the adhesive surface of the adhesive sheet 10, this part can be easily picked up. . Therefore, the release sheet 20 can be easily scraped off from this portion.

なお、第２折畳部２６の端縁２６ａは、粘着シートの第１辺１１に重なって延在している。したがって、図１においては、粘着シート１０の第１辺１１は、離型シート２０の第２折畳部２６の端縁２６ａと重なって現れる。
必ずしも、第２折畳部２６の端縁２６ａを、粘着シートの第１辺１１に重なるよう配置する必要はないが、このような構成を採用すると、製造ラインにおいて、「粘着シートを構成する基材」と「離型シートを構成する基材（折り畳まれた状態にある）」とを、重ねた状態で切断工程に送って、個々の粘着シートへと効率よく裁断できる。 In addition, the edge 26a of the 2nd folding part 26 has overlapped with the 1st edge | side 11 of the adhesive sheet, and is extended. Therefore, in FIG. 1, the first side 11 of the pressure-sensitive adhesive sheet 10 appears to overlap the edge 26 a of the second folding part 26 of the release sheet 20.
Although it is not always necessary to arrange the edge 26a of the second folding part 26 so as to overlap the first side 11 of the pressure-sensitive adhesive sheet, if such a configuration is adopted, in the production line, “the base constituting the pressure-sensitive adhesive sheet” will be described. The “material” and the “base material constituting the release sheet (in a folded state)” can be sent to the cutting step in an overlapped state, and can be efficiently cut into individual pressure-sensitive adhesive sheets.

≪楕円枠Ｂ内に示した例との比較≫
楕円枠Ａ内に示した上記実施形態では、第１折畳部２５の折畳線２５ａを、粘着シートの第１辺１１よりも内側（図３中右側）にズレた位置に延在させている。それに対して、楕円枠Ｂ内に示した実施形態のように、折畳部２５ａを、粘着シートの第１辺１１と重なる位置に配置することも可能である。しかし、楕円枠Ａ内に示した実施形態のように、折畳線２５ａを内側にズラして配置することで、次のようなメリットが得られる。
すなわち、もし仮に、折畳線２５ａを第１辺１１に沿って配置すると、製造ライン中での第１辺１１に沿う切断工程において、当該折畳線２５ａの位置で離型シート２０が切断され得る。そこで、これを防止するために、折畳線２５ａを、粘着シートの第１辺１１よりも内側（図３中右側）にズレた位置で延在させることが好ましい。 ≪Comparison with the example shown in the ellipse frame B≫
In the above embodiment shown in the ellipse frame A, the fold line 25a of the first fold part 25 is extended to a position shifted to the inner side (right side in FIG. 3) from the first side 11 of the adhesive sheet. Yes. On the other hand, like the embodiment shown in the ellipse frame B, the folding part 25a can be arranged at a position overlapping the first side 11 of the adhesive sheet. However, as in the embodiment shown in the ellipse frame A, the following merits can be obtained by disposing the folding lines 25a inward.
That is, if the folding line 25a is arranged along the first side 11, the release sheet 20 is cut at the position of the folding line 25a in the cutting process along the first side 11 in the production line. obtain. Therefore, in order to prevent this, it is preferable to extend the folding line 25a at a position shifted to the inner side (right side in FIG. 3) than the first side 11 of the adhesive sheet.

≪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、粘着シートの側片に沿う離型シート部分に折畳領域を設ければ、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 in the case where the pressure-sensitive adhesive sheet and the release sheet have a shape other than a rectangle, if a folding region is provided in the release sheet portion along the side piece of the pressure-sensitive adhesive sheet, the portion is changed as in the illustrated embodiment. The release sheet can be scraped off easily by picking.
