A container for fluid material including an upright tubular shell having a top end and a bottom end. The shell includes upright first sidewalls having a first width and an upright second sidewall having a second width that is less than the first width. The second sidewall is interdisposed between the pair of first sidewalls. The bottom end of the shell is closed, and a flexible impervious liner with a fitment attached for emptying the liner of fluid materials is located within the shell. A lower portion of the second (narrow) sidewall defines an outer opening with a vertical dimension greater than a cross-sectional portion of the fitment to be inserted therethrough. The second (narrow) sidewall has greater resistance than the first (wide) sidewall to transverse motion, which decreases the likelihood of structural failure of the container as a result of transverse motion of fitment and associated sidewall. Accordingly, locating the outer opening in the second (narrow) sidewall decreases the likelihood that the container will fail. A bottom cap covers the bottom of the container and includes a tab constructed of solid fiberboard with an inner opening having a horizontal dimension substantially greater than the cross-sectional portion of the fitment. The vertical dimension of the inner opening is less than the vertical dimension of the outer opening so that as the fitment moves in a vertical direction it will strike the top and bottom periphery of the inner opening, instead of the outer opening, thereby reducing damage to the outer opening.

Contenant pour fluides comportant une enveloppe tubulaire verticale avec extrémité supérieure et extrémité inférieure. L'enveloppe comporte deux parois, la deuxième paroi ayant un diamètre moindre que la première paroi. La deuxième paroi se trouve à l'intérieur de la première paroi. L'extrémité inférieure de l'enveloppe est fermée, et une doublure souple et imperméable avec raccord permet le vidage de l'enveloppe. L'extrémité inférieure de la deuxième paroi (étroite) comporte une ouverture extérieure dont la dimension verticale est supérieure à la portion transversale du raccord qui traverse la paroi. La deuxième paroi (étroite) possède une plus grande résistance au mouvement transversal, ce qui diminue le risque de bris structural en cas de déplacement du raccord et de la paroi correspondante. L'ouverture extérieure étant pratiquée dans la deuxième paroi (étroite), le risque de bris du contenant se trouve diminué. Un capuchon recouvre l'extrémité inférieure du contenant et comporte une patte faite de carton fort pourvu d'une ouverture intérieure dont la dimension horizontale est significativement plus grande que la section transversale du raccord. La dimension verticale de l'ouverture intérieure est moindre que la dimension verticale de l'ouverture extérieure, de sorte que tout mouvement vertical du raccord sera limité par la périphérie supérieure et inférieure de l'ouverture intérieure, ce qui réduit le risque d'endommager l'ouverture extérieure.
