Abstract: A divider for partitioning a rectangular space into six cells, formed from a blank comprising a central panel and a pair of panel sections. Each of the panel sections includes second, third, fourth and end panels extending in that order from the central panel. The widths of the second and fourth panels are equal, and the width of each end panel is greater than the width of the respective third panel, whereby when the fourth and end panels are folded flatly onto the second and third panels, an end portion of each end panel overlies a portion of the central panel. The blank is cut and further scored along a median portion to provide hinge means and to divide the panels into half-panels.
