发明名称 SEMI RIGID CONTAINER
摘要 A semi rigid container (20) comprising a plurality of generally rectangular side walls (22) and a bottom wall (26) attached to the bottom of each side wall. A plurality of flexible supporting frames (24) are attached to each side wall (22) to expand the container's open top and to brace the side walls (22) into a free standing container for handy storage, transportation or disposal of refuse or other articles. A drawstring (50) is provided along the top of the container for easy closure. The semi rigid container (20) is made by attaching the flexible supporting frames (24) 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 (20) can be easily collapsed into a stack of side walls, then coiled into three adjacent loops and inserted into a storing receptacle.
