Abstract: A longitudinally-opening container having a faceted tubular body is disclosed. The tubular body is formed by splitting a tube longitudinally, or from a single sheet of paperboard folded to form two end openings. End caps that cover each end opening are split in half along a central axis, forming sections having confronting edges along the median axis and bounded on either end by respective sections of the end caps. The container opens longitudinally into two trays connected by a living hinge. The living hinge is formed by a taped seam or a longitudinal fold in the body. The living hinge aligns the confronting edges to engage releasable locking means on those edges when the container closes. The locking means holds all the edges of the container in substantial alignment with each other.

Abstract: An octagonal container is formed from corrugated paperboard with overlapping flaps for eliminating gaps in the container bottom wall. Prestretched polypropylene straps are automatically applied to the container when in its flattened condition for providing girth support to the container when in its erected condition. The straps are positioned from the lower portion of the container side walls at ever increasing distances from each other for limiting container bulge when carrying products having varying effects on the container. With such an arrangement of straps, economically and environmentally desirable single and double wall corrugated paperboard can be used where typically triple wall and laminated paperboard containers are used.

A first embodiment exhibits special utility as a manually erectable box, while a second embodiment is adapted to be erected by automatic machinery.

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.
