Structure of box

Abstract

A structure of box includes a body having a foamed layer arranged at the outer side. The foamed layer has an outer surface forming an anti-skidding non-smooth surface and an inside surface bonded to an artificial fiber layer. The box body has an inner side formed by an artificial fiber lining layer. Rigid boards are interposed between the artificial fiber layer and the artificial fiber lining layer and stitching is applied to fix the foamed layer, the artificial fiber layer, and the artificial fiber lining layer together. The box body has a top edge covered by a covering layer. Hand-carrying handles are mounted to the outer surface of the box body in a symmetric manner. When expanded, the box maintains an expanded shape of a container, and when collapsed, the box is collapsed through the sites of stitching to form a flat configuration.

1 . A structure of box, comprising: a foamed layer set at an outermost layer of a box body, the foamed layer having an outer surface forming a non-smooth surface and an inner surface coupled to a layer of artificial fibers; a plurality of rigid boards interposed between the artificial fiber layer and a layer of artificial fiber based lining. 
     
     
         2 . The structure of box according to  claim 1 , wherein the foamed layer, the artificial fiber layer and the artificial fiber lining layer are fixed by stitching formed at bendable sections of the box body. 
     
     
         3 . The structure of box according to  claim 1 , wherein the box body has a top to which a covering layer is mounted. 
     
     
         4 . The structure of box according to  claim 1 , wherein the box body comprises hand-carrying handles mounted to an outer surface thereof in a symmetric manner.
