Description
(1)前記自立型外包装容器は、軟質積層フィルム製、硬質プラスチック製、紙製または金属製のいずれかであること、
(2)前記非自立型のだし素材入り調味液用ダブルパック包装体は、それの上端部横シール部が、前記自立型外包装容器内上端部に融着されて、該外包装容器内に懸吊された状態にて収容保持されていること、
(3)前記自立型外包装容器は、船底形の底部を有し、頂部は非自立型のだし素材入り調味液用ダブルパック包装体を交換するために開閉可能な構造を有すること、
がより好ましい解決手段を提供することになると考えられる。
例えば、
(a)フィルム状逆止ノズル:PE10/PET9/PE10=20μm厚で、包装袋本体:PET12/PE40=52μm厚
(b)フィルム状逆止ノズル:PE15/PET12/PE15=42μm厚で、包装袋本体:PET12/PE30=42μm厚
(c)フィルム状逆止ノズル:PE50/PET25/PE50=125μm厚で、包装袋本体:NY15/PE30=45μm厚
などのラミネートフィルム、押出しフィルムの適用が考えられる。
なお、積層フィルムは、それが2層または3層構造のいずれからなる場合においても、それぞれのシーラント層を、ベースフィルム層に対する溶融押出しラミネート法またはドライラミネート法、エクストルージョンラミネート法、コエクストルージョンラミネート法などによって積層することができる。
図1は、本発明に係るだし素材入り調味液用ダブルパック包装体8の正面図、図2はその斜視図を示すものである。このダブルパック包装体8は、軟質の積層フィルムからなる包装袋本体2のたとえば左側縁上部に、液状被包装物を注出するためのフィルム状逆止ノズル1を突設した例であり、該包装袋本体2の接合部の内表面側のシーラント層に、該フィルム状逆止ノズル1の基端部における最外層のシーラント層、好ましくは、包装袋本体2のシーラント層と同種の樹脂材料からなるシーラント層を重ね合わせてヒートシールして融着接合したものである。場合によっては、これらの融着接合部の注出通路13内面のシーラントフィルムを高融点のものとして、この部分が低温融着するようにして接合強度の弱い(袋本体の胴部を押圧して内圧を加えることで容易に剥離し、ノズルと本体との間を通過させる)仮封止部12を形成したものとすることができる。
即ち、それが0.3(N/15mm)未満では、加熱状態の液状被包装物の、袋内容量等との関連の下で、仮封止部12に意図しない開封が起こるおそれがあり、一方で、3(N/15mm)を越えると、仮封止部12を開封するのに要する荷重が、他の融着接合部等にも不測の影響(破袋や開封)を及ぼすおそれがある。
本発明において、自立型のディスペンサー機能をもつことが好ましい自立型外包装容器9は、例えば、一軸もしくは二軸延伸ベースフィルム層と、シーラント層とを具える積層フィルムからなり、ベースフィルムが、ポリエチレンテレフタレートフィルム層またはナイロン樹脂フィルム層からなり、一方、シーラント層が、ポリエチレン層またはポリプロピレン層からなる積層フィルムを用いた、スタンディングポウチP等の形態をとるものが好適に用いられる。しかし、本発明では、該外包装容器9として、こうした軟質フィルムからなる袋状のステンディングパウチPだけでなく、少なくとも本体部分は、自立する他の円筒状プラスチック容器や紙製(フィルムラミネートのものを含む)、アルミニウムやステンレス鋼などであってもよい。
<本発明適合例>
だし素材としてかつお荒節粗砕品3g、昆布粗砕品1gを、ポリエステルスパンボンド不織布(大紀商事株式会社製、フルベール)からなるフィルターバッグ内に封入し、これをフレキシブル包装袋内に収納した後、該包装袋内にだしを使用しないで調整した3倍濃厚つゆ300mlを、85℃達温にて熱充填して、本発明に適合するダブルパック包装体を作製した。
<比較例>
つゆ300mlあたり、かつお荒節粗砕品3g、昆布粗砕品1gを使用して抽出しただしを加えて調整した3倍濃厚つゆ300mlを、通常のフレキシブル包装袋(フィルム状逆止ノズルなし)内に85℃達温にて熱充填し、比較例である包装体を作製した。
なお、本発明適合例および比較例の包装体はいずれも、透明蒸着NY15/透明蒸着PET/LLDPE40からなる積層プラスチックフィルムによって作製した。また、濃厚つゆとしてはいずれも、つゆ300mlあたりに、濃口醤油90ml、砂糖45g、みりん30mlの他、食塩を塩分が10.5%になるように加えて調整したものを使用した。
