【考案の詳細な説明】
本考案は特に過酸化水素水等のガス発生性液体収納容器
の中蓋として使用するに適した新規な通気性中蓋に係わ
るものである。[Detailed Description of the Invention] The present invention relates to a novel breathable inner lid particularly suitable for use as an inner lid of a container for storing a gas-generating liquid such as a hydrogen peroxide solution.
従来過酸化水素水の如きガス発生性液体の収納容器は、
普通容器本体の口を中蓋で覆い、その上に上部が開口し
た外蓋を螺合してこの中蓋を緊締する様に構成されてい
るが、この中蓋としてはシリコン等の軟質材からなる円
形シートの中央に切れ目を入れたものが使用されている
。Conventional storage containers for gas-generating liquids such as hydrogen peroxide solution are
Normally, the opening of the container body is covered with an inner lid, and an outer lid with an open top is screwed onto the inner lid to tighten the inner lid, but the inner lid is made of a soft material such as silicone. A circular sheet with a cut in the center is used.
この場合ガスが発生すると内圧により切れ目からガスが
ぬける様になっているが、収納容器が傾いた場合にこの
切れ目から液が洩れる欠点がある。In this case, when gas is generated, the internal pressure allows the gas to escape through the slits, but there is a drawback that liquid may leak from the slits if the storage container is tilted.
そこで同様に中央に切れ目を入れたポリプロピレンシー
ト２枚の間に本考案に使用されるものと同様の液体不透
過性で且つガス透過性の膜をはさんでサンドインチ状に
構成したものも知られているが、この場合は三枚の膜を
使用するため、はめ込む時に手間がか＼つたり、お互に
ずれたりする等、取扱いが困難であるという欠点がある
。Therefore, there is also known a sandwich-like structure in which a liquid-impermeable but gas-permeable membrane similar to the one used in the present invention is sandwiched between two polypropylene sheets with a cut in the center. However, since three membranes are used in this case, there are disadvantages in that they are difficult to handle, such as requiring time to fit them together and causing them to shift from each other.
本考案はこれら従来のものの欠点を除いた新規な構造の
中蓋を提供するもので、実質上液体不透過性であり且つ
気体透過性であるプラスチックの膜の片面又は両面に気
体透過性のプラスチック製の布又は不織布よりなる多孔
性補強膜を熱接着してなる通気性中蓋である。The present invention provides an inner lid with a new structure that eliminates the drawbacks of the conventional ones, and includes a plastic film that is substantially liquid-impermeable and gas-permeable, and a gas-permeable plastic film on one or both sides. This is a breathable inner lid made by thermally bonding a porous reinforcing membrane made of fabric or non-woven fabric.
これを図面に示した一実施例により説明すると、第１図
に於て１は液体不透過性で気体透過性の例えば開孔セル

２はその両面に接着された多孔性材質のシートである。This will be explained with reference to an embodiment shown in the drawings. In FIG. 1, 1 is a membrane made of a liquid-impermeable but gas-permeable microporous polymer film of, for example, an open cell type;
2 is a sheet of porous material adhered to both sides thereof.
液体不透過性で気体透過性のプラスチックの膜としては
各種のものを使用し得るが、溶剤法、延伸法、電子線等

、ポリアセクールの如きポリニーテール、フッ素樹脂等
の疎水性プラスチックのミクロポーラスフィルムが例示
される。Various liquid-impermeable, gas-permeable plastic membranes can be used, including polyolefins such as polyethylene and polypropylene, polycarbonates, polyamides, and polyacecooles made porous by solvent methods, stretching methods, electron beams, etc. Examples include polynytails such as Polynylene Tail, and microporous films of hydrophobic plastics such as fluororesin.
特に孔径０．１μ程度のポリプロピレンのミクロポーラ
スフィルムが適当である。In particular, a microporous film of polypropylene with a pore diameter of about 0.1 μm is suitable.
この様な膜は例えば特公昭４６−４０１１９号公報記載

４００番としてポリプラスチックス■より市販されてい
るものを使用し得る。Such a film can be produced, for example, by the method described in Japanese Patent Publication No. 46-40119.
No. 400 commercially available from Polyplastics ■ may be used.
元に対してセルロース質等の親水性プラスチックよりな
る膜は水或は過酸化水素水等の液体を透過するため使用
し得ない。In contrast, membranes made of hydrophilic plastics such as cellulose cannot be used because they allow liquids such as water or hydrogen peroxide to pass through.
か＼るプラスチックの膜に接着されるプラスチック製の
多孔性材質としては、良好な通気性を有し、且つ適当な
強度を有するものが使用されるが、耐薬品性を有し且つ
上記の膜と接着性を有すること、しかもこの中蓋を外蓋
で締めつける時密封出来る様適度の平滑性と弾性を有す
ることが望ましい。As the porous plastic material to be bonded to such a plastic membrane, a material having good air permeability and appropriate strength is used, but a material having chemical resistance and the above-mentioned membrane is used. It is desirable that the inner cover has adhesive properties and also has appropriate smoothness and elasticity so that it can be sealed when the inner cover is tightened with the outer cover.
か＼る多孔性材質としては布又は不織布が用いられるが
、特にポリプロピレン製不織布が好ましい。As such porous material, cloth or nonwoven fabric can be used, and polypropylene nonwoven fabric is particularly preferred.
ポリプロピレンミクロポーラスフィルムはポリプロピレ
ン不織布と熱で容易に接着し、耐薬品性が良好で、液が
不透過であり、しかも通気性がよいので本考案の目的に
適した中蓋が容易に得られる。Polypropylene microporous film easily adheres to polypropylene nonwoven fabric by heat, has good chemical resistance, is impermeable to liquids, and has good air permeability, so an inner lid suitable for the purpose of the present invention can be easily obtained.
本考案の通気性中蓋は従来のものと同様過酸化水素水等
の収納容器の中蓋として好適に使用し得る。The breathable inner lid of the present invention can be suitably used as an inner lid for a storage container for hydrogen peroxide, etc., as well as conventional ones.
