Abstract
Abstract A collapsible partition assembly comprising a set of parallel longitudinal dividers and a set of parallel transverse dividers intersecting at a plurality of intersections. Each of the longitudinal dividers has a series of evenly spaced slots which extend downwardly from a top edge of the longitudinal divider to approximately the middle of the longitudinal divider. Each transverse divider has a series of evenly spaced slots, each slot extending upwardly from a bottom edge of the transverse divider to approximately the middle of the transverse divider. The slots of the longitudinal and transverse dividers engage with one another at the intersections. Dividers are secured to each other at each intersection by a securement bead which extends from a point proximate the top edge of the intersection to proximate the bottom edge of the intersection. The intersecting dividers create four angles. The securement bead runs along one angle and permits the partition assembly to be collapsed and recycled.
