An upright tubular shell has a top end, a bottom end, and a plurality of side-by-side sidewalls. The shell is constructed of a plurality of layers of paperboard material. A first one of the sidewalls defines a first portion adjacent a first upright edge of the first sidewall and has a thickness less than the thickness of the adjacent portion of the first sidewall. The first portion also comprises less than all of the plurality of layers of the paperboard material. The first portion overlaps and is attached to a second one of the sidewalls. A flexible impervious liner with an attached fitment is located within the shell. An outer opening is defined in one of the sidewalls proximate the bottom end for receiving a portion of the fitment. A bottom cap defines a first opening, a second opening, and a third opening. The first opening overlays the second opening. The outer opening is interdisposed between and aligned with the third and first openings.

Cette invention concerne une coquille tubulaire verticale comportant un fond supérieur, un fond inférieur et une pluralité de parois latérales juxtaposées. La coquille est faite d'une pluralité de couches de papier carton. Une des parois comporte à son extrémité supérieure une partie amincie par rapport au reste de la paroi. Cette partie amincie comporte moins de couches de papier carton que le reste de la paroi. Cette portion amincie chevauche une partie analogue de la paroi adjacente et y assemblée. Une doublure souple imperméable comportant un robinet se trouve à l'intérieur de la coquille. Une des parois comporte près de son extrémité inférieur une ouverture par où passer le robinet. Un fond inférieur définit une première, une deuxième et une troisième ouvertures. La première ouverture est juxtaposée à la deuxième ouverture. L'ouverture extérieure est intercalée entre la première et la troisième ouverture, dans l'alignement de celles-ci.
