Abstract
Description
本発明は、スパウトを持つ紙容器に関し、使用済み紙容器から容易にスパウトを分離することができる紙容器に関する。 The present invention relates to a paper container having a spout, and to a paper container capable of easily separating a spout from a used paper container.
柔軟性に富んだ紙包装材料は多年にわたって液体食品を包装するために用いられてきた。牛乳、果汁ジュース、野菜ジュース、豆乳、ワイン、清酒、焼酎、ミネラルウォーター、スープ及びその他飲料のための図４に示すような紙容器１は、例えば、繊維質基材（例えば、紙など）／プラスチック積層体に折目線が付けられたウェブ状包装材料を、その長手方向の縦線シールによりチューブ状に成形し、チューブ状に成形された包装材料内に液体食品を充填し、チューブ状包装材料を横断方向に横線シールし、枕状の包装体（一次形状容器）に成形する。
枕状の包装体を横シール部分で容器１個分ごとに切断し、最終成形工程で、折目線に沿って山折り若しくは谷折に、フィン及びフラップを折畳んで、図４に示すレンガ状の容器１が成形される。
Flexible paper packaging materials have been used for many years to package liquid foods. A paper container 1 as shown in FIG. 4 for milk, fruit juice, vegetable juice, soy milk, wine, sake, shochu, mineral water, soup and other beverages is, for example, a fibrous substrate (for example, paper) / A web-like packaging material with a crease line attached to a plastic laminate is formed into a tube shape by a longitudinal line seal in the longitudinal direction, and the liquid food is filled into the tube-shaped packaging material, and the tube-like packaging material Is transversely sealed in the transverse direction and formed into a pillow-shaped package (primary shape container).
A pillow-shaped package is cut into one container at a horizontal seal portion, and in the final molding process, fins and flaps are folded into mountain or valley folds along the crease line, and the brick shape shown in FIG. The container 1 is formed.
紙容器例１は、容器頂部に、図４（Ｂ）に示すように、スクリューキャップ６及びスパウト付き開封装置２を備える。この開封装置例では、図４（Ａ）に示すように、封止フィルム４が張られた開口部３上に、注ぎ口のスパウトとそれと螺合するスクリューキャップ６とからなる。（例えば、特許文献１参照） As shown in FIG. 4B, the paper container example 1 includes a screw cap 6 and a spout-equipped opening device 2 at the top of the container.
