〔考案の目的〕
（産業上の利用分野）
本考案は、たとえば薬品を収納するような防湿
対を有する包装袋に関する。[Detailed Description of the Invention] [Objective of the Invention] (Field of Industrial Application) The present invention relates to a packaging bag having a moisture-proof pair for storing, for example, medicine.
（従来の技術）
一般に用いられている包装袋は、セロフアンフ
イルムを素材としたものが多いが、セロフアンフ
イルムは、透湿性および透気性有するため、収納
される物品に制限があり、防湿を必要とする薬品
には適用し得ない。(Prior art) Most commonly used packaging bags are made of cellophane film, but because cellophane film has moisture permeability and air permeability, there are restrictions on the items that can be stored. It cannot be applied to the necessary drugs.
そこで包装袋を、一面に引裂強度の大きい樹脂
フイルムを、他面に熱接着性のよい樹脂フイルム

沿つて互いに熱接着し、防湿性、防気性を有する
ものとし、防湿を要求する薬品を収納し得るよう
にしたものも作られた。 Therefore, the packaging bag is made of a composite film that has a resin film with high tear strength on one side and a resin film with good heat adhesive properties on the other side, and is overlapped with the resin film with good heat adhesive properties on the inside. Some were made by thermally adhering the sides to each other to make them moisture- and air-proof, and to accommodate chemicals that required moisture-proofing.
上記形式の包装袋では、表面側に位置する引裂強
度の大きい樹脂フイルムが耐熱性に富みかつ印刷
容易性を有するから、セロフアン製包装袋に比べ

らない。In the packaging bag of the above type, the resin film with high tear strength located on the front side has high heat resistance and is easy to print, so it has superior properties compared to packaging bags made of cellophane. It takes considerable effort to tear the large resin film, which makes it difficult to open, and requires the use of scissors or a knife to remove the contents.
そこで、表面側に位置する引裂強度の大きい樹
脂フイルムの一側に、開口を形成するためのスリ
ツトを設け、小さな力で引裂強度の大きい樹脂フ
イルムを引き裂き得るようにした包装袋が提案さ
れた。 Therefore, a packaging bag has been proposed in which a slit for forming an opening is provided on one side of the resin film with high tear strength located on the front side, so that the resin film with high tear strength can be torn with a small force.
（考案が解決しようとする問題点）
しかし上記形式の包装袋では素材となる複合フ
イルムの製造においてスリツトを有する樹脂フイ
ルムを熱接着性のよい樹脂フイルムにラミネート
する際にスリツトが拡がつた状態で接合された

合い段部を形成したりすることがあり、複合フイ
ルムの不良品を多発させてしまうことがある。ま
たかかる不良品で包装袋を作ると、スリツトに沿
つて包装袋を開封できないことがある。(Problem to be solved by the invention) However, in the above-mentioned type of packaging bag, when laminating a resin film with slits to a resin film with good thermal adhesive properties in the production of the composite film material, the slits are expanded. The slits may be joined together, or one side edge of the slit may overlap the other side edge to form a step, resulting in a high number of defective composite films. Furthermore, if a packaging bag is made from such defective products, it may not be possible to open the packaging bag along the slits.
そこで本考案は上記した点に鑑みてなされたも
ので、複合フイルム製造時の不良品をなくすとと
もに防湿性を損なうことなく、開封を容易に行な
い得るようにした包装袋を提供することを目的と
する。 The present invention was developed in view of the above-mentioned points, and aims to provide a packaging bag that eliminates defective products during the production of composite films and that can be easily opened without compromising moisture resistance. do.
（問題点を解決するための手段）
本考案の包装袋では、素材となる複合フイルム
の表面側に位置する樹脂フイルムの一側に沿つて
上端部から下端部まで延びるスリツトを設けると
ともに、そのスリツトの中間位置に、スリツトに
連らなる切り離し線を有する連結部を設けて構成
される。
(Means for Solving the Problems) In the packaging bag of the present invention, a slit is provided along one side of the resin film located on the surface side of the composite film serving as the raw material, extending from the upper end to the lower end. A connecting portion having a separation line connected to the slit is provided at an intermediate position of the slit.
（作用）
本考案の包装袋において、端縁に設けたスリツ

には切り離し線が形成されているので、スリツト
の連結部の上下部分は一線上に切り離されること
になり、包装袋の開封時に開封線がスリツトから
ずれることがない。(Function) When the packaging bag of the present invention is opened along the slit provided at the edge, a separation line is formed at the connecting portion provided in the middle position, so the upper and lower portions of the connecting portion of the slit are in line with each other. This prevents the opening line from shifting from the slit when the packaging bag is opened.
（実施例） 以下本考案の一実施例を図面につき説明する。(Example) An embodiment of the present invention will be described below with reference to the drawings.

is formed along the side from the top to the bottom. This slit 8 is preferably so thin that it is difficult to discern it with the naked eye, and is
It is formed on a resin film 4 with high tear strength before being made. That is, the slit 8 has a diameter of approximately 5
It is made from a rotary cutting blade (not shown) with uncut parts provided at 180° intervals on the outer circumferential surface.
A separation line 10 connecting the slits 8 located above and below the connecting portion 9 is formed in the portion formed by the uncut portion of the slit, that is, the connecting portion 9. Further, a notch 11 is provided in the thermally bonded portion 3 so as to be continuous with the slit 8. The connecting portion 9 is
This serves to prevent the slits 8 provided in the resin film 4 from expanding during lamination and to prevent the side edges of the slits from overlapping each other.
