Claim:
A collapsible container configured for holding a bulk material load therein and operable to restrict tampering with the load, the collapsible container comprising: a box including a floor and a sidewall surrounding the floor, with the floor and sidewall being interconnected to form a load-receiving chamber that is operable to receive the bulk material load, said sidewall presenting an upper edge spaced upwardly from the floor, said box including a plurality of panels shiftably attached to a remainder of the box at a location spaced vertically between the floor and the upper edge and projecting uprightly above the sidewall in an extended position to expand the chamber, with the panels presenting uppermost edge sections that form an open container top and with the plurality of panels operable to be folded from the extended position to a retracted position, said plurality of panels being entirely within the chamber in the retracted position; and a lid including a rim that receives the uppermost edge sections, with the lid overlying the open container top to enclose the chamber, said sidewall including a ledge that is spaced within the chamber and extends along the upper edge with the lid operable to be received on the ledge to enclose the chamber when the plurality of panels are in the retracted position, said plurality of panels including a pair of adjacent panels with interconnected joint elements, said joint elements extending substantially from the upper edge to the rim and defining a seam therebetween, one of said joint elements presenting an external surface that covers the other joint element from the upper edge to the rim to restrict access through the seam and into the chamber.
