Abstract
Abstract A collapsible reusable shipping container construction of a type including a relatively rigid pallet which forms a floor, and erectable fiberboard walls and top which are hingedly connected to the pallet to be erected for use, and alternately folded against the pallet for empty return shipment. Hook and pile interconnecting means for interconnecting free edges of the side walls selectively to the pallet are provided, said means being so situated that the weight of the cargo tends to maintain the hook and pile means in engaged condition to prevent accidental disengagement.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
In a collapsible reusable shipping container of a type having a relatively rigid pallet element defining a floor, and a plurality of hingedly interconnected walls selectively engaged at the lower edges thereof to a surface of said pallet, improved means for accomplishing engagement of said lower edges comprising: a plurality of flaps hingedly interconnected to said side walls at said lower edges, and foldable to lie in a plane substantially at right angles with respect to the plane of a respective wall to overlie a portion of an upper surface of said rigid pallet elements; said flaps having a downwardly facing surface and cooperating hook and pile interconnecting means secured to said downwardly facing surface of said flaps and said upper surface of said pallet element, one of said flaps being interconnected to an edge surface of said pallet to permit said one of said flaps to remain attached to said pallet as the remaining flaps are disconnected prior to folding respective walls upon said pallet, and selectively allowing complete detachment of said walls for replacement.
Claim 2
