ABSTRACT:
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.
