Abstract: A container formed from a blank of corrugated board where cuts between panels on a hinge axis (defined by hinging bridges preferably adjacent an indexing projection) reveal the flute ends and thereby provide stack support for the base of an indexing like container. The indexing walls of the container are slightly inwardly inclined and each corner of the container has a reinforcement (column form) provided by extensions of the panels.

Abstract: A container formed from a blank to define indexing longer walls having an inward incline but a double thickness provided by a foldline at the tops thereof so that the indexing projections are receivable within corresponding openings in the base of a corresponding container. Each part of the indexing walls has an extension such that at each end thereof one extension attaches to the outside of an end wall while the other attaches to the inside of an end wall with preferably that attaching to the inside of an end wall through a pair of parallel vertical folds providing a support at least in part for the weight of a stacked container.

Abstract: A case forming panel and case structures incorporating the case forming panel, the material of which being a laminate of internal and exterior liners on a flute providing medium of corrugated board having a flute pitch in depth greater than that of "A" flute, the flutes to extend in use substantially vertically, and preferably having a flute pitch of about 54 mm, a flute depth of about 27 mm, and a take up of about 1.54:1.
