Description
量が230〜450g/m2程度の範囲内の晒しクラフト紙、マニラボール等の板紙を選択して使用することが好ましい。
ポリプロピレン系樹脂、ポリスチレン系樹脂、アクリロニトリル−スチレン共重合体(AS樹脂)、アクリロニトリル−ブタジェン−スチレン共重合体(ABS樹脂)、ポリカーボネート系樹脂、エチレン−プロピレン共重合体(EP)、エチレン−αオレフィン共重合体、エチレン−アクリル酸共重合体(EAA)、エチレン−メタクリル酸共重合体(EMAA)、エチレン−メタクリル酸エステル共重合体、エチレン−アクリル酸エステル共重合体、アイオノマー樹脂、エチレン−酢酸ビニル共重合体(EVA)などの樹脂、その他の熱可塑性成形用樹脂を使用することができる。また、前記容器口部(2)は、必要に応じて顔料などで着色されていてもよい。
本発明に係る注出口付き紙容器を構成する胴部(1)には、図8に示すように、紙基材層(13)として、坪量230g/m2の晒クラフト紙を使用し、最外層には、低密度ポリエチレン樹脂をエクストルージョンラミネーション方法により、厚さ30μmの熱可塑性樹脂層(12)を形成し、最内層には、低密度ポリエチレン樹脂をエクストルージョンラミネーション方法により、厚さ60μmの熱可塑性樹脂層(15)を形成した積層材料を用いた。
実施例1において、胴部(1)の材料構成が、最外層面側から、低密度ポリエチレン樹脂(30μm)/晒クラフト紙(230g/m2)/低密度ポリエチレン樹脂(25μm)/酸化珪素蒸着膜(30nm)/ポリエチレンテレフタレートフィルム(12μm)/接着剤/低密度ポリエチレン樹脂フィルム(60μm)からなる積層材料を用いた以外は実施例1と同様にして実施例2の注出口付き紙容器を得た。
前記実施例1及び実施例2の紙容器を専用の液体自動充填包装機にそれぞれ供給し、容器底部(4)の成形、ジュースの充填工程後、低密度ポリエチレン樹脂製のキャップ(6)を取り付けて、外観を観察した所、図7に示すように、出来上がり製品が側面から見てストレートになり、見栄えが良い注出口付き紙容器の製品化が可能になった。
