Abstract
A cardboard retaining structure defined by a peripheral strip joined at the ends to form a continuous loop and creased to form fold lines thereacross. The fold lines are spaced to define substantially equal front and rear panels in the strip separated by substantially equal lateral panels. The loop therefore may be collapsed into a folded planar structure one or more separator panels extend between the front and rear panels and the front panel is provided with a notched flap to engage the edge of the separator panel in an orthogonal alignment therewith.
Claims3
A collapsible containment structure comprising:
- a substantially rectangular pripheral strip of elongate form having the ends thereof joined to each other to form a continuous loop and including a plurality of crease lines formed thereacross for defining folds therein, said crease lines being spaced to provide a front and a rear panel each of substantially equal rectangular plan form and a first and second lateral panel interspaced therebetween;
- a separator panel extending between said front and rear panels, said separator panel including an arcuate edge cutout proximate said front panel;
- and
- an arcuate flap formed in said front panel adjacent said edge cutout and including a notch at the apex thereof for engaging said edge cutout, whereby said notch upon the engagement of said cutout aligns said separator panel substantially orthogonal to said front panel.
