ABSTRACT:
A partition (10) installable in a container (X) for dividing its interior into a plurality of cells (C1-C12), more or less. The partition includes a first panel (12) having at least one score, crease or fold (14) therein by which the panel can be folded. The first panel may include a pair of panels having contiguous edges about which they pivot with respect to each other, in a manner similar to said folded first panel. The partition also includes second and third panels (20, 22) which are attachable to the first identified panel(s) at the fold(s), or edge separation. These latter panels have interfitting tabs (26a, 26b), that interfit intermediate each other. The second panel is attached to a sidewall of the first panel on one side of the fold and the third panel is attached to the sidewall on the other side of the fold. The panels move apart when the first panel is folded at the crease thereby to create the walls of the cells. Each tab has an inner segment (28) adjacent the end of the panel, an intermediate segment (30), and an outer segment (32). The inner and outer tab segments taper along their lengths; while, the intermediate segment has a constant width to provide a pivot shoulder between adjacent tabs. As a result, the only contact between the second and third panels, when the first panel is folded, is at the intermediate shoulder segments of adjoining tabs. Adjacent interfitted tabs may be slightly spaced from each other for clearance.
