A collapsible case comprises a closed loop of flexible sheet material for forming the top, bottom and sidewalls of the case, the loop having front and rear edges defining front and rear openings into the interior of the loop. A pair of similar panels form the front and rear walls of the case, each panel including a sheet of flexible material having a perimeter, stiffeners attached to the sheet so as to tension and stiffen the sheet into a selected shape and fasteners for fastening the perimeter of the sheet to the corresponding edge of the loop so that when the panels are fastened to the loop, the loop assumes the selected shape and when said panels are unfastened from the loop and the stiffeners are detached from the sheets, the loop and sheets may be collapsed and consolidated.

[ What is claimed is:] [1.]1. A collapsible case comprisinga closed loop of flexible sheet material for forming the top, bottom and side walls of the case, said loop having front and rear edges defining front and rear openings into the interior of the loop;a series of relatively stiff battens secured to said loop between said edges at spaced-apart locations all around said loop, said battens being substantially perpendicular to said edges thereby allowing the loop to be flattened and rolled up into a generally cylindrical package,a pair of similar panels for forming the front and rear walls of the case, each panel includinga sheet of flexible material having a perimeter,means for stiffening said front and rear walls,attachment means for removably attaching said stiffening means to said sheet so as to tension and stiffen said sheet into a selected shape, andfastening means for fastening the perimeter of the sheet to the corresponding edge of the loop so that when said panels are fastened to said loop, said loop assumes said selected shape and when said panels are unfastened from said loop and said stiffening means are detached from said sheets, said loop and panels may be collapsed and consolidated into said cylindrical package.
