Abstract: A prefabricated fully assemblable bird cage comprising a flat sheet of stiff material, a rectangular panel, formed centrally in the sheet bounded on the outside perimeter thereof by four straight prefold marginal depressions, defining respectively a top margin, opposed side margins and a bottom margin, each fold line arranged orthogonal to the other, the fold lines joined at their respective intersecting terminal ends to form a central panel of the enclosure, the rectangular panel having formed therein a large central opening, the edges of which reside in the panel; first and second end panels extending outward from the central panel including a first portion of each end panel that is arranged to be folded orthogonal to the central panel; opposed side panels extending respectively outward from the panel margins for folding toward each other in parallel arrangement to form respectively side panels of the cage; a pair of wide, short tabs extending from the straight prefold marginal edge depression formed in the

Abstract: A counter or wall display for cards or brochures is made from a single stamping which is die-cut to define both the perimeter of the unit and at the same time stamp score lines partially through the material to define the hinge lines. The score lines divide the single sheet into connected front, floor and rear panels, and a pair of side panels which hinge rearwardly from the front panel and have edges which interlock with the edges of the rear panel, so that an open-topped box display is formed from a single sheet of planar stock with no fasteners whatsoever.

Abstract: A picture frame is defined from a single stamping of preferably clear plastic sheet material wherein the sheet is stamped into a front face with a pair of rearwardly bending sidewings, and a base consisting of a horizontally extended bottom plane and an upwardly, forwardly extended brace plane, the upper tips of the brace plane defining inwardly-directed pegs which engage holes in tabs on the sidewings to hold the sidewings back and to hold the base in its supporting configuration. When folded into this configuration, the material of which the frame is preferably made exhibits sufficient memory and tension to hold the unit tautly together, and the rearwardly bent and held sidewings define tracks or slots for the insertion of a photograph or the like from the top.
