Abstract: A reusable, collapsible, bulk container having pairs of opposed side walls, each of which has foldably joined to the lower end thereof a narrow bottom wall retaining flange. The retaining flange of one side wall is permanently adhesively secured to a margin of a bottom wall panel, and the other flanges are coated with a pressure sensitive type of adhesive substance adapted to releasably adhere to, upon contact with, other marginal portions of the bottom wall panel when said carton is erected.

Abstract: A bulk box and slip sheet construction. The one piece paperboard blank from which the bulk box is formed has a plurality of main, side forming panels, the lower end of each foldably carrying a bottom forming panel. At least one of the bottom forming panels is provided with a slip sheet. The slip sheet is glued to at least one of the box bottom forming panels. One edge of the slip sheet, termed a clamping edge, extends from its bottom forming panel to a region beyond the fold line which connects this bottom forming panel to its respective side forming panel. After the blank has been erected, this clamping edge can be clamped to pull the box onto a slip sheet lift truck for transport and/or stacking. More than one slip sheet can be employed, or a longer single slip sheet, to thereby provide the bulk box with more than a single clamping edge portion.
