Abstract: A collapsible laundry container structure having a base, an upper frame, a cover body, four supporting frames, six engaging members, and a water-proof bag is disclosed. The four supporing frames are engaged with the base and the upper frame by rivets to form two pairs of two-story supporting frames, and further fixed by the engaging members stopped with rececees and insert grooves disposed at one lateral side of each supporting frame so as to expand tightly and evenly the water-proof bag outside the supporting frames. In dismantling, the two-story supporting frames are pushed inward from outside the water-proof bag at the spot of the engaging members with the capacity of collapsible fold so as to fold and store the supporting frames neatly upon the base with the upper frame overlaid above. In addition, circular holes are disposed at the base to boost the circulation of air and a corrugated flange is provided at the bottom of the base to form a stable footing for supporting the base on the ground.
