【０００１】
【発明の属する技術分野】
本発明は、果汁飲料、調味料、洗剤及び化粧品などの詰替え用パウチの注出口部に挿着する注出用口部材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口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口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】
しかしながら、上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、内容物を充填する前に、パウチ本体は平坦であるが注出口部が立体構造になっているため、流通及び保管時の集積効率が悪く、また、内容物充填時に、充填機内での包装袋の搬送上のトラブルが発生し易く、このため、特殊な搬送装置などを必要とすることがあった。
【０００４】
本発明は、上述の従来の注出口部付パウチの問題を解決したものであり、注出口部がパウチ本体と同様に平坦で、流通及び保管時に、パウチの集積効率が良好であり、内容物注出時には、ワンタッチで注出口部を注出し易い立体構造にできる注出用口部材付パウチを提供するものである。

【００１６】
【作用】
本発明の注出用口部材付パウチは、内容物を充填されるまでは、注出用口部材を挿着する注出口部もパウチ本体と同様に平坦であるため、流通及び保管時の集積効率が良く、内容物充填機上でのパウチの搬送上のトラブルがなく、搬送のための特殊な装置を必要としない。
【００１７】
また、本発明のパウチの注出口部に挿着された注出用口部には、パウチの外側から指で折り曲げるためのヒンジやスリット又はねじ曲げるためのスリットが形成されており、また、形成された立体構造を維持するための嵌合凸部、嵌合凹部又は嵌合部が設けられており、内容物の注出するときに、立体構造になった剛性をもつ合成樹脂製の注出用口部が、柔軟な合成樹脂フィルムから形成される注出口部を内側から筒状の開口状態に維持して内容物の流路を確保するため、パウチの注出口部からの内容物の注出が良好となる。
【００１８】
また、注出口部の注出孔に挿着する注出用口部材の折り曲げ部分の外側縁部又は全体を、折り曲げ方向へ所定の角度だけ傾斜させた本発明の注出用口部材付パウチは、パウチの外側から注出用口部を指でつまみ、中心方向へ力を加えるだけで、注出用口部が始から折り曲げ方向へ所定の角度だけ傾斜しているため、自然に、所定方向へ折り曲がる。
【００１９】
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注出用口部材付パウチは、注出口部の透明又は半透明側のパウチ外側から、注出孔に挿着する注出用口部材を目視できるため、注出用口部材の組み立て状況を確認しながら組み立てができ、注出用口部材の組み立てを確実にすることができる。

次に、本発明の注出用口部材付パウチから内容物を注出する操作を、一実施形態例の図１（ａ）、図１（ｃ）及び図１２（ｂ）を用いて説明する。まず、図１（ａ）に示す注出口部（２１０）の先端シール部をノッチ（２１２）から指で引き裂くか、鋏などで切断して除去して注出口を開口する。次に注出口部（２１０）の左右のシール部分（２０１）を指でつまみ注出用部材（１００）を、図１２（ｂ）に示すように、ヒンジ（１１０）を介して断面く字状に折り曲げる。この操作により注出用口部材の注出口に接着されていない側面が立ち上がり、注出口部の他面のフィルムを押し上げ、注出口が開口する。そして、折り曲げ操作をさらに進めると、図１（ｃ）に示すように、注出用口部材（１００）の嵌合凸部（１４０）と嵌合凹部（１５０）とが嵌合して、注出用口部材（１００）が断面く字状になった状態で折り曲げ作業は完了する。上述の嵌合凸部（１４０）と嵌合凹部（１５０）との嵌合により、図１２（ｂ）に示すように、注出用口部材（１００）は組立状態が維持され、このことにより注出口の開口状態も流路（２１１）をもって維持される。この開口状態の注出口から内容物が注出する。
【００３３】
また、他の実施形態例についても、図１３（ｂ）乃至図２２（ｂ）に示すように、同様に注出用口部材（１００）を折り曲げて、嵌合凸部と嵌合凹部、嵌合凸部と嵌合凸部、嵌合部と嵌合凸部を嵌合させて注出用口部材の組立状態を維持することで、流路（２１１）をもって注出口を開口させ、かつこの開口状態を維持させることで内容物を良好に取り出すことができる。
【００３４】
また、パウチの注出口部に挿着する注出用口部材を立体構造にするときに、パウチの外側から注出用口部材の状態を目視するために、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てもよい。なお、パウチにガスバリア性などを必要とする場合には、基材の積層フィルムの構成層中に、アルミ、シリカなどの透明又は半透明の無機化合物の蒸着層を設けてることができるが、不透明なアルミニウム箔層、アルミニウム蒸着層などは設けられない。また、通常、パウチの注出口部の全体又は開封維持部材の全体又は一部分に相当する部分には、印刷層を設けてはならない。
【００３５】
なお、上述の実施形態例の注出用口部材を注出口部に挿着した本発明の注出用口部材付パウチは、流通及び保管時の集積効率が良く、内容物充填機上でのパウチの搬送に係わるトラブルの発生がなく充填効率が良好であった。また、内容物を充填したパウチの注出口部の先端を切断して開封し、パウチの外側から注出用口部材を指で、ヒンジを折り曲げて嵌合凸部を嵌合凹部に又は嵌合凸部を嵌合凸部に嵌合させるか、上方部をスリットによりねじ曲げて嵌合部を嵌合凸部に嵌合させて、注出用口部材を立体構造にし内容物を注出してみたが、口部材の立体構造化が容易であり、また高粘度の内容物でも内容物の注出状態が良好であった。
【００３６】
また、本発明は上述した実施形態例に限定されるものではなく、注出用口部材の構成も、平板状で剛性をもつ合成樹脂であって、折り曲げ可能でかつ折り曲げ状態を維持する嵌合機能をもち、パウチの注出口部内に挿着可能な構造であれば良い。また、その寸法は、巾については注出口部に応じて自由に設定することができ、高さについては注出口部の寸法範囲内とすることもできるし、注出口部の寸法を越えた長さとして、パウチの注出口部に挿着したときにパウチ本体内に、注出用口部材の下部が入り込むようにすることもできる。さらに、注出用口部材に設ける折り曲げ手段として前記実施例ではヒンジ又はスリットをあげたが、この他に、ミシン線、半切れ線などの手段を採用でき、注出用口部材の材質、厚みなどを選定することで特別な構造をこうじることなく、折り曲げ手段とすることもできる。ここで、上述の実施形態例の図面ではヒンジを形成する凹溝の位置（表面側か裏面側）は、図面の位置に限定されることなく任意に設定できるものである。
【００３７】
また、パウチに形成する注出口部も上述の実施形態例のようなパウチの角部に斜め方向に突出する形態のほかに、パウチの上部角部又は上部中央部に上方向に突出する形態、パウチの側部角部、側部中央部、側部下部に横方向に突出する形態とすることもできる。
【００３８】
さらに、パウチの注出口部に注出用口部材を収容するパウチの表面方向へ膨らむ窪みを形成することもできる。この窪みは、パウチの表裏フィルムの一方若しくは両方（好ましくは本発明のパウチを製造する際に注出用口部材を置く側のフィルム）に、注出用部材の外周形状と等しいか大であり、この注出用口部材を収容可能な大きさで、その深さは注出用口部材の厚み相当か、それ以上かそれ以下にして設けるものである。
【００３９】
【発明の効果】
本発明の注出用口部材付パウチは、注出用口部材を挿着した注出口部も包装袋本体と同様に平坦であるため、流通及び保管時の集積効率が良く、内容物充填機上でのパウチの搬送上のトラブルがない。
【００４０】
また、内容物を充填した本発明の注出用口部材付パウチは、内容物を注出するときに、注出用口部材を外側から指で容易に立体構造にすることができ、この立体構造の注出用口部材が注出口部を開口状態に維持するため、内容物の注出性が良好であり、高粘度の内容物でも注出し易い。
【００４１】
また、注出用口部材の折り曲げ部分の外側縁部又は全体を傾斜させて、注出口部に挿着する注出用口部材を所定方向へ曲げ易くすることもでき、さらには、注出口部に挿着する注出用口部材をパウチの外側から目視可能にすることもできる。
