Description

【０００１】
【発明の属する技術分野】
本発明は、液体洗剤、トイレタリー、果汁飲料及び調味料などの詰替え用パウチに関するもので、詳しくは、内容物を注出し易く、リクローズ可能な開口維持部材付パウチに関するものである。
【０００２】
【従来の技術】
近年、環境保全や省資源の立場から、各種の液体内容物に詰替え用容器が広く使用されるようになってきた。この詰替え用容器としては、使用時に注出口部の先端を切断して開口し、内容物を注出する合成樹脂フィルムからなる柔軟な注出口部付パウチがあるが、他の容器へ内容物を詰め替えるときに、注出口部の内容物の注出のし易さを改善するために、例えば、特開平８−２５３８号公報に記載されいる注出口部の注出孔を中空円筒状又は中空半円筒状に成形したものや、特開平９−２４９５６号公報に記載されている注出口部の注出孔に半硬質ないし硬質パイプを埋没したものなどが知られていた。
【０００３】
【発明が解決しようとする課題】
ところで、最近、さらに、環境保全や省資源の立場から、詰替え容器の容量を増やして、一本で数回の詰替えが可能な詰替え用パウチが求められるようになってきた。このため、詰替え用パウチにリクローズ機能が必要となってきた。また、リクローズ機能のある詰替え用パウチは、本品としての使用も可能となる。しかしながら、前述した従来の内容物の注出性を改善した注出口部付パウチは、リクローズ機能がなく、これらの要望に応えることができなかった。

【００１９】
【作用】
本発明の第１乃至第４の発明のリクローズ可能な開口維持部材付パウチは、注出口部の先端を切断し、注出口部内に挿着する開口維持部材の縦の線状折り曲げ部をパウチの外側から指で内側へほぼ９０°折り曲げて嵌合係止すると、内容物の流路をもつ立体構造となり流路が確保されるため、内容物を注出口部から安定して注出し易い。
【００２０】
また、本発明の第５乃至第１３の発明のリクローズ可能な開口維持部材付パウチは、注出口部の先端を切断すると、注出口部内に内容物の流路をもつ立体構造の開口維持部材が挿着されているため、内容物を注出口部から安定して注出し易い。
【００２１】
そして、本発明の第１乃至第４の発明のリクローズ可能な開口維持部材付パウチは、内容物を注出したのちに、パウチの外側から指で縦の線状折り曲げ部を元の平らな状態に戻して開口維持部材を平板状にし、横の線状折り曲げ部を内側へほぼ１８０°折り曲げて、パウチの折り曲げ内側になる合成樹脂フィルムを挟み込んで上方部を下方部に嵌合係止すると、パウチの注出口部をリクローズすることができる。なお、再度、内容物を注出するときには、嵌合を外し横の線状折り曲げ部を元の平らな状態に戻して、縦の線状折り曲げ部を折り曲げて開口維持部材を内容物の流路をもつ立体構造にし、注出口部を開口する。
【００２２】
また、本発明の第５、第６、第１０乃至第１２の発明のリクローズ可能な開口維持部材付パウチは、内容物を注出したのちに、パウチの外側から指で上下方向のほぼ中央部を湾曲させて内側へほぼ１８０°折り曲げて、折り曲げ内側になる合成樹脂フィルムを挟み込んで上方部を下方部に嵌合係止すると、パウチの注出口部をリクローズすることができる。なお、再度、内容物を注出するときには、嵌合を外して中央部を元の平らな状態に戻して、注出口部を開口する。
【００２３】
また、本発明の第７乃至第９の発明のリクローズ可能な開口維持部材付パウチは、内容物を注出したのちに、パウチの外側から指で横の線状折り曲げ部を内側へほぼ９０°折り曲げて、パウチの折り曲げ内側になる合成樹脂フィルムを挟み込んで上方部を下方部に嵌合係止すると、パウチの注出口部をリクローズすることができる。なお、再度、内容物を注出するときには、嵌合を外して縦の線状折り曲げ部を元の平らな状態に戻して、注出口部を開口する。
【００２４】
また、本発明の第１３の発明のリクローズ可能な開口維持部材付パウチは、パウチの外側から指で平板の中央位置に垂直に枢着する半円状の開閉板を水平位置に回転させて嵌合係止すると、開閉板の外周縁部がパウチの注出口部の内面に密接して、パウチの注出口部をリクローズすることができる。なお、再度、内容物を注出するときには、嵌合を外して開閉板を垂直位置に回転させて、注出口部を開口する。
【００２５】
また、注出口部の表裏の合成樹脂フィルムの少なくとも片側を透明又は半透明にした本発明の第１４の発明のリクローズ可能な開口維持部材付パウチは、注出口部の透明又は半透明側のパウチ外側から注出口部に挿着する開口維持部材を目視することができるため、開口維持部材を内容物の流路をもつ立体構造にする操作やリクローズする操作を、パウチの外側から指で容易に確実にすることができる。
【００２６】
【発明の実施の形態】
本発明のリクローズ可能な開口維持部材付パウチ（１０）は、図１４に示すように、使用時に先端を切断して開口する注出口部（２１０）をもち、表裏の合成樹脂フィルムの周縁部をシール（２０１）してなる柔軟なパウチ（２００）の注出口部内に、リクローズ可能な開口維持部材（１００）を上下方向を注出方向に平行させて挿着し、内容物を注出したのちに、開口維持部材付パウチを上下方向のほぼ中央位置で折り曲げてパウチの注出口部を折り曲げ、折り曲げ内側になる合成樹脂フィルムを挟み込んで嵌合係止してパウチをリクローズするものである。この開口維持部材は、使用目的に適応した特性をもつポリエチレン、ポリプロピレンなどの熱可塑性樹脂を用いて、射出成形法により作製するものであり、パウチの注出口部の内面に、部分的に接着剤で接着するか又は熱融着して、パウチの注出口部内に挿着するものである。

【００２８】
本発明の一実施形態のリクローズ可能な開口維持部材付パウチ（１０）は、例えば図１（ａ）に示すように、パウチ（２００）の注出口部（２１０）内に、四角形状で平板状の開口維持部材（１００）を縦の線状折り曲げ部（１０１，１０２）を注出方向に平行にして挿着するものである。この開口維持部材は、図１（ａ）に示すように、左右方向を２本の上端から下端にわたる平行な２本の縦の線状折り曲げ部（１０１，１０２）を設けて三分し、この２本の縦の線状折り曲げ部を内側へほぼ９０°折り曲げたときに、嵌合して図１（ｂ）に示す内容物の流路をもつ立体構造を維持し合う嵌脱可能な嵌合部を上方部と下方部のそれぞれに設けるものであり、図１（ａ）に示すように、上方部（１１０）には３個の嵌合部（１１１，１１２，１１３）を、下方部（１３０）にも３個の嵌合部（１３１，１３２，１３３）を設けるものである。このときの嵌合は、切り欠き状の嵌合部（１１１）と突起状の嵌合部（１１２）、突起状の嵌合部（１１２）と切り欠き状の嵌合部（１１３）、突起状の嵌合部（１３１）と切り欠き状の嵌合部（１３２）、切り欠き状の嵌合部（１３２）と突起状の嵌合部（１３３）とが嵌合するものである。また、上下方向のほぼ中央位置に左端から右端にわたる１本の横の線状折り曲げ部（１０３）を設けて二分し、この横の線状折り曲げ部（１０３）を、図１（ｃ）に示すように、内側へほぼ１８０°折り曲げてパウチの注出口部（２１０）を折り曲げたときに、折り曲げ内側になる合成樹脂フィルムを挟み込んで嵌合し合う嵌脱可能な嵌合部を上方部と下方部のそれぞれに設けるものであり、このときの嵌合は、嵌合部（１１１）と嵌合部（１３１）、嵌合部（１１２）と嵌合部（１３２）、嵌合部（１１３）と嵌合部（１３３）とが嵌合するものである。なお、線状折り曲げ部は、例えば裏面に図１（ａ）に示す切込み（１０５）を設けて線状の薄肉部を形成して設けるものである。
【００２９】
そして、内容物を注出するときに、図１（ｂ）に示すように、注出口部（２１０）の先端を切断して開口し、パウチ（２００）の外側から指で開口維持部材（１００）の２本の縦の線状折り曲げ部（１０１，１０２）を内側へほぼ９０°折り曲げて嵌着し、内容物の流路（１４０）をもつ立体構造にして内容物の流路を確保する。また、内容物を注出したのちに、パウチの外側から指で縦の線状折り曲げ部を元の平らな状態に戻して開口維持部材を平板状にし、図１（ｃ）に示すように、横の線状折り曲げ部（１０３）を内側へほぼ１８０°折り曲げて、パウチの折り曲げ内側になる合成樹脂フィルムを挟み込んで上方部（１１０）を下方部（１３０）に嵌合係止すると、注出口部（２１０）がリクローズされるものである。

【発明の効果】
本発明のリクローズ可能な開口維持部材付パウチは、注出口部内に平板状又は立体構造の開口維持部材を挿着しているが、内容物を注出するときに、注出口部の先端を切断し、平板状の開口維持部材はパウチの外側から指で容易に流路をもつ立体構造にでき、また、立体構造の開口維持部材はそのままで流路をもち、内容物の流路が確保されるため、内容物を注出口部から安定して注出することができる。
【００５８】
また、本発明のリクローズ可能な開口維持部材付パウチは、内容物を注出したのちに、立体構造にした平板状の開口維持部材は元の平らな状態に戻し、立体構造の開口維持部材はそのまま、パウチの外側から指で上下方向のほぼ中央位置を折り曲げてパウチの折り曲げ内側の合成樹脂フィルムを挟み込んで上方部を下方部に嵌合係止すると、パウチの注出口部を容易にリクローズすることができる。また、半円状の開閉板が枢着する開口維持部材は、開閉板を垂直から水平位置に回転することにより、パウチの注出口部を容易にリクローズすることができる。
【００５９】
また、注出口部の表裏の合成樹脂フィルムの少なくとも片側を透明又は半透明にした本発明のリクローズ可能な開口維持部材付パウチは、パウチの外側から注出口部に挿着する開口維持部材を目視することができ、開口維持部材を立体構造にする操作やリクローズする操作がし易い。
