A semi rigid container comprising a plurality of generally rectangular side walls and a bottom wall attached to the bottom of each side wall. A plurality of flexible supporting frames are attached to each side wall to expand the container's open top and to brace the side walls into a free standing container for handy storage, transportation or disposal of refuse or other articles. A drawstring is provided along the top of the container for easy closure. The semi rigid container is made by attaching the flexible supporting frames to one or more sheets of flexible material, layering the sheet or sheets, and sealing the open margins of the layered sheet or sheets corresponding to the container's sides and bottom. The semi rigid container can be easily collapsed into a stack of side walls, then coiled into three adjacent loops and inserted into a storing receptacle.
