Abstract
A void filler device for use in staggering paper rolls during shipment includes a housing member which generally surrounds an inner core. The housing member has a top wall, a bottom wall, and side walls which are attached to the core, and is octagonally shaped. The top and bottom walls of the housing include fold lines around which the walls are folded to collapse the void filler device. The inner core member includes a plurality of flat boards made of laminated paperboard, corrugated cardboard, plastic or other like suitable material. Each of the boards has spaced notches along its length and the boards are interconnected with each other along the notches to form an open cell construction that is expandable and collapsible. The top and bottom walls can include apertures therein for ensuring that the paper rolls are properly aligned.
