ABSTRACT:
A structural form is constructed of a single sheet of material, such as cardboard, which is cut along certain lines and folded to provide a three dimensional configuration. The sheet material is cut to provide tabs each extending from a side of a respective panel portion. The panel portions, when folded, form the outer side walls of an enclosure. The tabs at opposite edges of each panel are folded into the enclosure to form channel members. Every alternate one of the tabs is provided with additional perforations, such that it can also be folded to nest an adjacent tab when all of the tabs are folded inwardly of the side wall panel portions. The tabs are folded such that a first portion thereof, which is secured to its respective panel portion slopes inwardly and toward the center of the enclosure. The remaining portion of each tab is folded to extend from a central area within the enclosure to a respective one of the panel portions. All of the edges of the tabs bear at right angles against the internal surfaces of the panel portions to provide a relatively rigid structure when assembled.
