ABSTRACT:
A collapsible void filler is provided which, when in an expanded state, prevents relative movement between cargo during transit. The void filler is formed as a pair of side panels, a pair of bases secured to the side panels, and at least one beam structure located in the interior defined by the side panels and the two bases. The side panels include side panel portions which fold about a longitudinal axis when the void filler is collapsed. The bases, which may be formed from one or more base panels, extend transversely between the side panels and move toward and way from one another when the void filler is collapsed and expanded. The beam structures may have several different configurations, each of which has a pair of beam panels hingedly connected to the bases and foldable with respect to one another. The beam structures operate to support the side panels against transverse compression when the void filler is expanded. The void filler is preferably made from a unitary piece of material.
