Abstract:
A recyclable foldable turnover box, comprising an outer box bag (1) and an inner support frame (2), wherein the outer box bag wraps the inner support frame, the outer box bag comprises a box bag body (3) and a box cover body (4), and a connected opening and closing structure (5) is arranged between the box cover body and the box bag body; and the inner support frame is arranged in the outer box bag and is configured to support and shape the outer box bag, and folding hinge structures (6) are arranged on two symmetrical side frames of the inner support frame, so that the inner support frame can be folded, and the whole turnover box can be folded by means of the folding of the inner support frame. The outer box bag of the turnover box can be unfolded and shaped when using same by means of the inner support frame in the outer box bag, and can also be synchronously folded by means of the folding of the inner support frame, thereby folding the whole turnover box; moreover, the folding hinge structures on the inner support frame do not fold when subjected to a vertical stacking force, and thus a strong support strength is provided; the structure is simple, and cyclic operation and use are facilitated; and the outer box bag also has a good sealing performance, and achieves moisture-proof and heat-insulation effects.
