本発明は、包装袋に関する。具体的には、医薬品、菓子（特に、ＰＴＰ（プレススルーパッケージ）包装シート）等を収容する包装袋に関する。   The present invention relates to a packaging bag. Specifically, it is related with the packaging bag which accommodates a pharmaceutical, a confectionery (especially PTP (press through package) packaging sheet), etc.

プラスチックフィルムを含む積層シートから構成されるガゼット形式の包装袋は、コンパクトに、かつ、効率良く梱包できることから、近年、様々な分野で用いられている。   In recent years, gusset-type packaging bags composed of laminated sheets including plastic films have been used in various fields because they can be packed compactly and efficiently.

上記ガゼット形式の包装袋はコンパクトに梱包できる反面、開封時に引き裂き部分が内容物にぶつかってしまい、内容物を取り出すには十分な開口部を確保できないという問題がある。そこで、開封用切り欠きと背シールに平行な開封補助線とを所定の部位に設けることで、内容物にぶつかっても直線状に開封し、かつ側面の折り込み部分を全て取り去ることができる包装袋が提案されている（特許文献１）。   The gusset-type packaging bag can be packaged in a compact manner, but there is a problem that a torn part hits the contents when opened, and a sufficient opening cannot be secured for taking out the contents. Therefore, by providing a notch for opening and an opening assisting line parallel to the back seal at a predetermined site, the packaging bag can be opened linearly even if it collides with the contents, and all the folded portions on the side surface can be removed. Has been proposed (Patent Document 1).

しかし、簡便な操作で開封可能であり、かつ、内容物を容易に取り出すことのできる包装袋が継続的に望まれている。   However, a packaging bag that can be opened by a simple operation and from which contents can be easily taken out is continuously desired.

図示するように、包装袋１００は、プラスチックフィルムを含む積層シートをシールして袋状に形成して構成されている。包装袋１００は、積層シートの両端部をシールすることにより、上下方向に沿って背シール部１が裏面１０側に形成されている。この背シール部１と、上端縁部をシールした上端シール部２と、下端縁部をシールした下端シール部３とによって収容部４０を形成している。   As shown in the drawing, the packaging bag 100 is configured by sealing a laminated sheet including a plastic film and forming it into a bag shape. In the packaging bag 100, the back seal portion 1 is formed on the back surface 10 side along the vertical direction by sealing both end portions of the laminated sheet. The back seal portion 1, the upper end seal portion 2 that seals the upper end edge portion, and the lower end seal portion 3 that seals the lower end edge portion form an accommodating portion 40.

包装袋１００は、裏面１０と裏面１０に対向する前面２０と、裏面１０と前面２０との間に形成される左右の側面３０，３０とを有する。左右の側面３０，３０は折り込んだ状態とされ、この状態のまま上端縁部と下端縁部がシールされている。   The packaging bag 100 includes a back surface 10, a front surface 20 facing the back surface 10, and left and right side surfaces 30, 30 formed between the back surface 10 and the front surface 20. The left and right side surfaces 30, 30 are folded, and the upper edge and the lower edge are sealed in this state.

包装袋１００は、背シール部１と上端シール部２と下端シール部３とによって形成された収容部４０に、内容物４１を収容する。このように形成したガゼット形式の包装袋１００はマチがあるので、断面四角形状の筒状に形成され、例えば、図２に示すように、ＰＴＰ包装シートを複数枚まとめて、コンパクトに包装することができる。   The packaging bag 100 accommodates the contents 41 in the accommodating portion 40 formed by the back seal portion 1, the upper end seal portion 2, and the lower end seal portion 3. Since the gusset-type packaging bag 100 formed in this way has a gusset, it is formed in a cylindrical shape with a square cross section, for example, as shown in FIG. Can do.

包装袋１００には、左右の側面３０，３０それぞれに、開封補助線３１ａ，３１ｂが形成されている。開封補助線は、上下方向に沿って直線状に側面の中央部に形成されている。１つの実施形態においては、開封補助線は、側面３０，３０の上端から下端まで形成されている。さらに、開封補助線は、側面３０，３０の折り込んだ折り目上に形成されている。このような構成であれば、図３に示すように側面を両側（前面方向および裏面方向）に引っ張るだけの簡便な操作で開封することができる。さらに、このような構成であれば、側面の上端から下端まで開封（切断）することができるので、内容物を取り出すための開口部を十分に大きくすることができる。結果として、内容物を容易に取り出すことができる。加えて、このような構成であれば、開封時に袋を切断しないのでゴミが出ない、および、袋の表面を切断しないので印刷の表示面を広く使用することができるという利点を有する。   In the packaging bag 100, opening assist lines 31a and 31b are formed on the left and right side surfaces 30 and 30, respectively. The opening assist line is formed in the center of the side surface in a straight line along the vertical direction. In one embodiment, the opening assistance line is formed from the upper end to the lower end of the side surfaces 30, 30. Further, the opening assist line is formed on the folded folds of the side surfaces 30 and 30. If it is such a structure, as shown in FIG. 3, it can open by simple operation which only pulls a side surface to both sides (front direction and back direction). Furthermore, since it can open (cut | disconnect) from the upper end of a side surface to a lower end if it is such a structure, the opening part for taking out the content can be enlarged enough. As a result, the contents can be easily taken out. In addition, such a configuration has the advantage that the bag is not cut at the time of opening, so that no dust is produced, and since the surface of the bag is not cut, the printing display surface can be widely used.

包装袋１００には、好ましくは、左右の側面３０，３０それぞれに、防滑層５０，５０が形成されている。防滑層を側面に形成することにより、開封者の開封操作がさらに容易となり、かつ、側面の上端から下端まで確実に開封することができる。防滑層５０は、側面３０，３０全面に形成されてもよく、側面３０，３０の所定の位置（例えば、開封者の親指が置かれる位置）に選択的に形成されてもよい。防滑層５０は、好ましくは、側面３０，３０全面に形成される。開封者が異なる場合であっても統一的な効果が得られ、かつ、防滑層の形成（最終的に、包装袋の製造）が容易だからである。なお、見やすくするために、図１では防滑層は側面の一部にのみ表示されており、図２では省略されている。   The packaging bag 100 is preferably provided with anti-slip layers 50 and 50 on the left and right side surfaces 30 and 30, respectively. By forming the anti-slip layer on the side surface, the opening operation of the unsealing person is further facilitated, and the side surface can be reliably opened from the upper end to the lower end. The anti-slip layer 50 may be formed on the entire surface of the side surfaces 30, 30, or may be selectively formed at a predetermined position on the side surfaces 30, 30 (for example, a position where the thumb of the unsealing person is placed). The anti-slip layer 50 is preferably formed on the entire side surfaces 30 and 30. This is because even if the opening person is different, a uniform effect is obtained, and the formation of the anti-slip layer (finally, the manufacture of the packaging bag) is easy. In addition, in order to make it easy to see, the anti-slip layer is displayed only on a part of the side surface in FIG. 1, and is omitted in FIG.

防滑層５０は、より好ましくは、裏面１０および前面２０にも形成されている。防滑層を裏面および全面にも形成することにより、開封者の開封操作が格段に容易となる。防滑層５０は、裏面１０および前面２０の全面に形成されてもよく、裏面１０および前面２０のそれぞれの所定の位置（例えば、開封者の人差し指が置かれる位置）に選択的に形成されてもよい。防滑層５０は、好ましくは、裏面１０および前面２０の全面に形成される。なお、見やすくするために、図１では防滑層は裏面および前面の一部にのみ表示されており、図２では省略されている。   More preferably, the anti-slip layer 50 is also formed on the back surface 10 and the front surface 20. By forming the anti-slip layer on the back surface and the entire surface, the unsealing operation of the unsealing person becomes much easier. The anti-slip layer 50 may be formed on the entire surface of the back surface 10 and the front surface 20, or may be selectively formed at a predetermined position (for example, a position where an opener's index finger is placed) on the back surface 10 and the front surface 20. Good. The anti-slip layer 50 is preferably formed on the entire back surface 10 and front surface 20. In addition, in order to make it easy to see, in FIG. 1, the anti-slip layer is displayed only on a part of the back surface and the front surface, and is omitted in FIG.

防滑層５０は、例えば、羽毛粉末とバインダーと分散媒とを含む塗工液を積層シート表面に塗布および乾燥することにより形成され得る。防滑層の厚みは、例えば５μｍ〜５００μｍである。羽毛粉末を含む防滑層をこのような厚みで形成することにより、包装袋の開封に非常に適切な防滑性および取扱い性を実現することができる。塗工液および形成方法の詳細は、例えば特開２０１０−２８５５０２号公報に記載されている。当該公報の記載は、本明細書に参考として援用される。   The anti-slip layer 50 can be formed, for example, by applying and drying a coating liquid containing feather powder, a binder, and a dispersion medium on the surface of the laminated sheet. The thickness of the anti-slip layer is, for example, 5 μm to 500 μm. By forming the anti-slip layer containing the feather powder with such a thickness, it is possible to realize anti-slip property and handleability very suitable for opening the packaging bag. Details of the coating liquid and the forming method are described in, for example, Japanese Patent Application Laid-Open No. 2010-285502. The description of the publication is incorporated herein by reference.

開封補助線は、積層シートをレーザー照射（例えば、炭酸ガスレーザーによる）等によりハーフカットすることにより形成される。包装袋を構成する積層シートは、基材層とヒートシール可能な最内層とを有し、開封補助線は、最内層に形成されていないことが好ましい。   The opening assist line is formed by half-cutting the laminated sheet by laser irradiation (for example, by a carbon dioxide laser) or the like. It is preferable that the lamination sheet which comprises a packaging bag has a base material layer and the innermost layer which can be heat-sealed, and the opening assistance line is not formed in the innermost layer.

積層シートとしては、従来から使用されているもの、例えば、二軸延伸ポリプロピレン、二軸延伸ポリアミド、二軸延伸ポリエステル等からなるフィルムを基材層とし、これらの基材層に、低密度ポリエチレン、直鎖状低密度ポリエチレン、エチレン−酢酸ビニル共重合体、ポリプロピレン等のポリオレフィン系樹脂を最内層として積層した積層体が用いられる。積層シートは、ドライラミネート法、押出ラミネート法、共押出法などにより製造され、基材層と最内層との間には接着強度の向上のため、接着剤やアンカー剤等を介することができる。得られる包装袋の強度を高めるために、基材層を複数枚の積層体としてもよい。また、気体や紫外線のバリア性を高めるため、アルミニウム箔等の金属箔、金属蒸着層、セラミック等の無機質蒸着層、エチレン−ビニルアルコール共重合体フィルムなどを積層してもよい。   As a laminated sheet, what is conventionally used, for example, a film made of biaxially stretched polypropylene, biaxially stretched polyamide, biaxially stretched polyester, etc. is used as a base layer, and in these base layers, low density polyethylene, A laminate in which a polyolefin resin such as linear low density polyethylene, ethylene-vinyl acetate copolymer, and polypropylene is laminated as the innermost layer is used. The laminated sheet is produced by a dry lamination method, an extrusion lamination method, a coextrusion method, or the like, and an adhesive or an anchoring agent can be interposed between the base material layer and the innermost layer in order to improve the adhesive strength. In order to increase the strength of the resulting packaging bag, the base material layer may be a plurality of laminated bodies. Moreover, in order to improve the barrier property of gas and ultraviolet rays, you may laminate | stack metal foils, such as aluminum foil, metal vapor deposition layers, inorganic vapor deposition layers, such as a ceramic, an ethylene-vinyl alcohol copolymer film.
