ABSTRACT:
A cellular space divider for cartons and the like is disclosed that is formed from a blank of sheet material such as corrugated cardboard. The blank contains vertical first scorelines that define front, rear, and a pair of side panels. One of the panels contains a horizontal first fold line, and the remaining panels each contain throughout substantially the length thereof a first cut colinear with the first fold line, whereby the panels are divided into lower first and upper second panel sections. When the panels are folded about the first score lines to define a tube and the adjacent ends of the panels are connected together, the lower and upper panel sections define lower and upper cell units, respectively, the upper cell unit being foldable about the first fold line to a position in which the external surfaces of the panel sections joined by the first fold line are in contiguous engagement, thereby to define a multi-cell arrangement. Another panel may be provided with a horizontal second fold line at a higher elevation than the first fold line, the remaining panels being provided with second cuts colinear with the second fold line, thereby to define a third cell unit that is foldable about the second fold line to a position in which the external surfaces of the panel sections on opposite sides of the second fold line are in contiguous engagement. In one embodiment, the rear panel is unitary, and in a second embodiment, the rear panel includes a pair of rear panel sections that are connected at their free ends, a divider panel being provided that is connected with one rear panel section and is foldable to a position extending transversely across the tube.
