Abstract
A collapsible box includes: a bottom panel, a front panel, a rear panel, a left-side panel, a right-side panel and a top panel for forming a box of parallelepiped shape, each panel consisting of a plurality of bamboo strips juxtapositionally connected with one another by at least a fastening member transversely linking the bamboo strips, each panel having at least a reinforcing rib secured with the plurality of bamboo strips and each panel having a pair of opposite end portions each forming an acute angle of 45 degrees, whereby upon folding of the two neighboring panels, the two acute angles of the two neighboring reinforcing ribs will form a right angle for forming a strong stable right-angle elbow structure of the two neighboring reinforcing ribs as assembled by the two neighboring panels; and upon tying of the fastening members on an assembled box by folding the plurality of panels, the box as assembled can be strongly durably constructed for storing foods or goods therein; and upon unfolding of the panels and untying of the fastening members, the box may be unfolded and flattened to be a compact volume, convenient for transportation and re-use at a lower cost.
