US Patent 7631799 Container and blank for making the same

A collapsible storage device includes a collapsible container and a lid for the container. The container includes a plurality of resilient wall panels and a hinge portion connecting each adjacent pair of wall panels. The container may be foldably converted between a substantially flat collapsed position and a substantially rectangular prismatic expanded position by articulating the wall panels about the flexible hinges. At least one of the hinge portions is arched to latch the container in the expanded position. The lid may be used to cover the container in the expanded position and receive the container in the collapsed position.
