ABSTRACT:
A pallet base for a corrugated board case comprises a tray having a flat central zone and a foldable margin which, when folded from a flat state to an erect state, defines peripheral feet which incorporate flaps which can be folded inwards to overlie the central zone and thereby maintain peripheral tray flaps of the pallet base in an erect position. The inwardly foldable flaps may be held turned in through at least 90.degree. by elastic bands which are readily removable to return the base to a fully flat condition.
