Abstract
A kit of parts constructed for ready assembly into a box and comprising a blank consisting of at least three juxtaposed side panels, a covering for each of the side panels, and end panels formed with projections and recesses for engagement with corresponding recesses and projections, respectively, on the side panels; wherein the covering is made of a repeatedly deformable elastomeric or sheet metal material, and each side panel, where adjacent to another side panel, is provided with projections and recesses which interlock with similar projections and recesses on the adjacent side panel. The kit is adapted to be assembled into box form by successive folding of the side panels into engagement with the end panels.
Claims5
A collapsible assembly of panel members capable of being readily assembled into a transport box for the storage and transport of relatively heavy cargo therein and capable of being disassembled into a flat for the efficient storage thereof comprising
- a blank member including at least three rigid side panels engageably spaced with respect to one another and a flexible supporting cover to which said rigid side panels are fixedly secured in said spaced relationship, said side panels being disengaged when said blank member is substantially flat, said side panel members having complementary projections and recesses adjacent one another and said projections and recesses having a depth dimension equal to the thickness of said panel members, said projections and recesses of each panel member lockingly engaging one another in mutually supportive perpendicular directions when said blank member is folded into a box, and
- a pair of end panels having a plurality of projections engageable with complementary recesses in the ends of said side panel members, said projections of the end panels having a depth dimension at least equal to the thickness of said side panels.
