[0013] Referring to FIG. 1, a folding collapsible bag in accordance with the present invention comprises a support frame structure, which comprises a first base member 1A, a second base member 1B, a first supporting element 2A and a second supporting element 2B.

[0014] The first base member 1A and the second base member 1B are flat plate members made from a tough and hard material. The first base member 1A and the second base member 1B are horizontally arranged on the bottom side and kept apart for supporting the bottom side of the folding collapsible bag in shape. The first supporting element 2A and the second supporting element 2B are respectively prepared from a resilient wire rod and bent into a substantially arched shape. Further, the first supporting element 2A and the second supporting element 2B are respectively arranged above the first base member 1A and the second base member 1B.

[0015] FIG. 2 illustrates an alternate form of the support frame, in which the first base member 1C and the second base member 1D are respectively prepared from a resilient wire rod and bent into a substantially arched shape.

[0016] Referring to FIG. 3, the folding collapsible bag further comprises a bag body 3 made from a soft fabric or any suitable flexible sheet material. The bag body 3 can be configured subject to any desired shape, having an opening on the top side. The first base member 1A or 1C and the second base member 1B or 1D are set in and affixed to the bag body 3 to stretch the bottom panel of the bag body 3 into a planar shape. The first supporting element 2A and the second supporting element 2B are bilaterally obliquely set in and affixed to the bag body 3 to stretch the periphery of the bag body 3 into shape, keeping the top open side of the bag body 3 opened. When turning the first base member 1A or 1C toward the first supporting element 2A and the second base member 1B or 1D toward the second supporting element 2B, the folding collapsible bag is collapsed into a flat condition (see FIGS. 4 and 5).
