Cellular void filler

摘要

An expandable honeycomb slab constructed from sheet material of corrugated paperboard, for filling load voids within a container carrying articles of freight. A plurality of horizontal cell rows, each containing a central diamond-shaped cell straddled by a pair of square-shaped cells, is stacked in vertical relation. Vertically adjacent corners and apexes of the cells are interconnected so as to allow vertical expansion of the suspended cellular array under its own weight. The vertically aligned, centrally positioned diamond-shaped cells provide vertical support and horizontal rigidity for the array, effectively preventing the honeycomb slab from assuming an hourglass configuration.
