Abstract: The present invention presents an air bag, and a method of using the same, which has at least one indicator line marking thereon for providing a visual indication of when the air bag is in a properly inflated condition for filling a void between loads, such as cargo or the like, in a truck, airplane, train or the like. Each indicator line includes a center portion which is of a first design, such as being blue-colored, and having easily identifiable ends. Preferably, each indicator line has end portions of a second design, such as being red-colored, which are on opposite sides of the center portion of the line and which are visually distinct from the first design. The center portion of the indicator line has a length which is substantially equal to the maximum thickness of the air bag.

Abstract: A void filler device for use in staggering or spacing apart items, such as paper rolls, during shipment includes a plurality of L-shaped members made of laminated paperboard, corrugated cardboard, plastic or other like suitable material. Each of the members has a first leg and a second leg which is angled approximately 90.degree. relative to the first leg. The first leg includes a plurality of spaced slots, which extend approximately half of the width of the first leg, by which the members interlock with each other to form an open-cell construction that is expandable and collapsible. The void filler expands and collapses by the members moving relative to each other.

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.
