【発明の詳細な説明】
（産業上の利用分野）
本発明は複合シートに関し、更に詳しくは、それ自体が
各種の薬剤を包蔵することができるため各種の薬効を発
揮することができる複合シートに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a composite sheet, and more particularly, to a composite sheet that can itself contain various drugs and thus exhibit various medicinal effects. .
（従来の技術）
従来から重版されている各種の包装用シートや下敷用シ
ート部材などにおいては、クッション性１通気性を高め
る努力がなされている。しかしながら、シート部材それ
自体が薬効を有するものはいまだ開発されていない。(Prior Art) Efforts have been made to improve the cushioning properties and breathability of various packaging sheets and underlay sheet members that have been reprinted in the past. However, a sheet member itself that has medicinal effects has not yet been developed.
例えば、タンスや押入れに衣類、ふとん等を収納する場
合、これらの環境は日光も当らず湿気も高いので衣類、
ふとん等にカビが発生したりまた家ダニ等の害虫が発生
し易いので、まず、これらの環境に新開紙、布マットな

剤のような各種薬剤の粉末を散布したりまたは薬剤のパ
ックを散在せしめたりしている。これは、従来のシート
部材がそれ自体としては薬効を有しないことからして当
然のことである。For example, when storing clothes, futons, etc. in a drawer or closet, these environments are exposed to no sunlight and have high humidity, so clothes, futons, etc.
Since mold and other pests such as house mites are likely to grow on futons, etc., first place a hygroscopic sheet material such as Shinkai paper or cloth mat as an underlay in these environments, and place clothing, futons, etc. on top of it. At the same time, various chemical powders such as antifungal agents, preservatives, and insecticides are sprayed or chemical packs are scattered. This is natural since conventional sheet members do not have medicinal properties in and of themselves.
（発明が解決しようとする問題点）
このように従来は、各種の薬効が求められる環境におい
てもシート部材は単にシート部材としての機能を果たす
のみであった。仮に、シート部材それ自体が必要される
薬効をも発揮するとすれば、その、シート部材の有用性
は極めて高まるものと考えられる。(Problems to be Solved by the Invention) As described above, in the past, sheet members merely functioned as sheet members even in environments where various medicinal effects were required. If the sheet member itself were to exhibit the required medicinal efficacy, the usefulness of the sheet member would be greatly increased.
このような要求に対し、シート部材の表面に各種の薬剤
を塗布したり担持させたりしたものも存在するが、しか
しながら、このような態様のものは薬剤と収納物とが直
接接触するので、収納物を汚染したり、薬剤が簡単に離
脱したりするので好ましいものではない。In response to these demands, there are sheet members in which various drugs are coated or supported on the surface of the sheet member. This is not preferable because it can contaminate things and the drug can easily be released.
本発明は、それ自体が薬剤を包蔵していて、収納物を汚
染することなく各種の薬効を発揮することができる新規
な構造の複合シートの提供を目的とする。An object of the present invention is to provide a composite sheet with a novel structure that contains drugs and can exhibit various medicinal effects without contaminating stored items.

ートであってもよく、この場合には、成形された複合シ
ートがクッション効果も発揮するので有用である。The impermeable sheet may be any sheet that retains water under constant temperature and pressure, does not allow moisture, air, etc. to permeate, and is highly flexible, such as low density polyethylene film, high Examples include thermoplastic plastic film sheets such as density polyethylene film, polypropylene film, polyvinyl chloride film, polyvinylidene chloride film, polyamide resin film, and composite films thereof. It may also be a variety of waterproof sheets, or even a closed-cell protruding plastic sheet with a plurality of protruding air chambers formed on its surface; in this case, a molded composite This is useful because the sheet also has a cushioning effect.
多孔性シート２は、後述する接着性ウェブ３に含有若し
くは担持されている薬剤３ａが液状で滲出したりまたは
ガス状で拡散放出されたりする程度の透孔が無数に分布
しており、かつ撥水性を有する可撓性のシートであれば
何であってもよい。The porous sheet 2 has numerous pores distributed through it, which allow the drug 3a contained or supported on the adhesive web 3 (described later) to ooze out in liquid form or diffuse and release in gaseous form, and is repellent. Any flexible sheet may be used as long as it is water-based.

熱ロールに移送し、１２０℃の温度で全体を融着した。A polypropylene sheet, a Guinac sheet, and a porous polyethylene sheet were layered in this order and continuously transferred to a hot roll, and the whole was fused at a temperature of 120°C.
融着は１００〜２０メツシユ相当の網状融着とした。３
層は接合され剥離するということはなかった。The welding was a net-like welding equivalent to 100 to 20 meshes. 3
The layers were bonded and did not delaminate.
