This is because damage may occur.
- the cylindrical plastic film constituting the inner bag 20 is provided with a plurality of deaeration hole groups 29, 29,... Penetrating into and out of the inner bag 20 as a deaeration mechanism.

Abstract
Description
内袋20は、少なくとも1層のプラスチックフィルムで構成されている。このプラスチックフィルムの材質としては、具体的には、ポリオレフィン樹脂、エチレン- 酢酸ビニル共重合体、ナイロン、ポリビニルアルコール、ポリスチレンなどが挙げられる。これらは、単独で又は適宜組み合わせて使用できる。なお、本発明においては、後述するプラスチックフィルムの厚さの範囲で脱気機構を設けることができれば、これらの材質に限定されない。
内袋20を構成する筒状のプラスチックフィルムには、脱気機構として内袋20の内外に貫通する複数の脱気孔群29、29、・・・が設けられている。このように脱気孔群を設けるのは、製造ライン上で内袋のプラスチックフィルムに簡便な方法で穿孔形成でき、他の材料を組み込むなどの必要がなくコストも抑えられるためである。複数の脱気孔群29、29、・・・は、プラスチックフィルムの周方向に直交する方向(通常、本発明のフレキシブルコンテナ1の上下方向に一致する。)に、所定幅の帯状の配列25とされている。各脱気孔29は、本発明のフレキシブルコンテナ1への充填物(不図示)の充填後に、内袋20の内部に残留する空気を自然に又は内袋20内の内圧の上昇に伴い脱気可能であり、かつ内袋20を通して当該充填物の脱漏や外部からの異物混入がないように形成されている。
外袋10は、角筒状胴部11と、当該胴部11の四隅上方で本発明のフレキシブルコンテナ1を吊り上げるためにそれぞれ縫合部31、31、31、31を介して取り付けられている吊りベルト30、30、30、30と(本明細書では、それぞれの吊りベルト30が胴部11から延設される方向を「上」とし、胴部11の開口方向反対側を「下」とする。)、胴部11の上側の開口を塞ぐ上面12と、胴部11の下側の開口を塞ぐ下面16とを備えている。本実施形態における外袋10は、角筒状胴部11、上面12及び下面16は通気性を有している。上面11の中央領域は開口しており、当該開口に円筒状の投入部13の一方の開口端が固定されるとともに、当該開口の端縁を菊割れ構造の上蓋14、14、・・・の基端側が取り付けられている。また、下面16の中央領域も同様に開口しており、当該開口に円筒状の排出部17の一方の開口端が固定されるとともに、当該開口の端縁に菊割れ構造の下蓋18、18、・・・の基端側が取り付けられている。上蓋14、14、・・も下蓋18、18、・・もこれらの先端側に縛りテープ15、19がそれぞれ設けられている。これらのテープ15、19を絞ることで、個々の上蓋13及び下蓋18が投入部13及び排出部17をそれぞれ内部に取り込んだ状態で上面12及び下面16の開口をそれぞれ塞ぐようになっている。なお、外袋10の外形形状については本実施形態に特に制限されず、角筒状胴部11の下面16の中央領域に排出部17のない構成であってもよい。
[内袋の作製]
厚み0.070mmのポリエチレン製内袋に、図1、図2A及び図2Bに示すように、マイクロパーフォレーション装置にて当該内袋の流れ方向に連続して100mm幅の帯状にMP孔の穿孔加工を行った。内袋は、インフレーションフィルム成形装置で筒状に製造されており、この筒状フィルムを半分に折り畳んだ状態でマイクロパーフォレーション装置に通すため、上下のフィルムのそれぞれに、即ち内袋の円周において対角に100mm幅の帯状のMP孔の配列を形成した。この配列において、個々のMP孔の孔径は0.100mmであり、隣接するMP孔間は6mmピッチとした。
ポリプロピレンを原料とするフラットヤーンを作製し、これを縦糸及び横糸とし織機で織ることで、ヤーン生地を得た。このヤーン生地を用いて円筒状胴部と上部投入部とを形成し、これらをミシン縫いによって縫合することで、円筒状の外袋を作製した。この外袋は、通常のクロスコンテナに相当するものである。こうして得られた外袋に内袋を内装することで、内外二重構造のフレキシブルコンテナを作製した。
