ABSTRACT:
An expandable void filler which includes a plurality of expandable hollow, elongated, box-like tubes which can be stacked one on the other and joined together along their common surfaces. Separate interface panels can be sandwiched between the individual tubular members to provide additional lateral compressive strength. The individual tubes are held in the expanded position by individual folding panels which extend inwardly across the interior opening within and have sufficient size to wedge against the opposite sidewall as well as the top and bottom of the structure. These panels alternate from one side of the tube to the other and are staggered so as to not be vertically aligned between the stacked tubular members. A flange member can be attached to the uppermost tube to support the void filler in proper position between the cargo loaded within a transporting vehicle. The double tubular configuration of the present invention can be formed by using a single sheet of material such as corrugated cardboard with the sheet folded along predetermined lateral fold lines to form the complete structure.
