DOUBLE CONTAINER

PROBLEM TO BE SOLVED: To provide a double container constituted of an outer container and an inner bag, which can solve the problem caused by a paper-made outer container.SOLUTION: The double container is constituted of an outer container and an inner bag, where the inner bag has a plug for pouring out contents, and the outer container as a whole is constituted of resin films, has a bottom surface and a side surface linked to the bottom surface and is formed in a substantially rectangular parallelepiped shape. The side surface is constituted of four side surfaces: a front side surface, a right side surface, a rear side surface and a left side surface. In at least two boundary parts of four boundary parts between the side surfaces are provided self-standing holding parts for holding self-standing of the outer container. On the front side surface is provided a plug extraction hole through which the plug is extracted.SELECTED DRAWING: Figure 1 【課題】紙製外容器に起因する問題を解決する外容器と内袋からなる２重容器を提供することを課題とする。【解決手段】外容器と内袋からなる２重容器であって、前記内袋は内容物を注出する口栓を有し、前記外容器は全体が樹脂フィルムで構成され、底面と前記底面に連接する側面を有して略直方体形状を成していて、前記側面は、前方側面、右側面、後方側面、及び左側面の４つの側面からなり、各側面同士の４つの境界部のうち少なくとも２つの前記境界部には、前記外容器の自立を保持する自立保持部が設けられ、前記前方側面には前記口栓を取り出す口栓取出孔が設けられていることを特徴とする２重容器。【選択図】図１
