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.

We claim: 1. A container, comprising: a plurality of wall panels hingedly connected so as to articulate between an expanded position and a collapsed position, the wall panels defining at least a bottom wall having four peripheral edges, a first side wall, a second side wall, a third side wall, and a fourth side wall; wherein each of the first, second, third, and fourth side walls is hingedly connected to a different one of the peripheral edges of the bottom wall; and wherein the second side wall is connected to the first side wall at an arched elongate hinge, the second side wall is hingedly connected to the third side wall, the third side wall is hingedly connected to the fourth side wall, and the fourth side wall is hingedly connected to the first side wall; wherein each of the first side wall, the third side wall, and the bottom wall comprises at least two wall panels defining a hinged connection extending substantially between diagonal corners thereof, wherein each of the second side wall and the fourth side wall comprises at most one wall panel, wherein the wall panels are adapted to articulate between the expanded position and the collapsed position about the arched elongate hinge and the hinged connections, and wherein the hinged connection extending substantially between the diagonal corners of the first side wall bulges outwardly to lock the container in the expanded position. 2. The container of claim 1, wherein each of the wall panels is articulably connected to each adjacent wall panel. 3. The container of claim 1, wherein the bottom wall is substantially square. 4. The container of claim 1, wherein at least one of the wall panels has a non-linear edge. 5. The container of claim 1, wherein the second side wall is hingedly connected to the third side wall at a second arched elongate hinge, the third side wall is hingedly connected to the fourth side wall at a third arched elongate hinge, and the fourth side wall is hingedly connected to the first side wall at a fourth arched elongate hinge. 6. The container of claim 1, wherein the arched elongate hinge comprises a plurality of tabs, the tabs connecting the first side wall and the second sidewall, and a notch disposed between adjacent tabs. 7. The container of claim 1, wherein the wall panels comprise a resilient cellulosic material. 8. The container of claim 7 further comprising a substantially liquid impermeable coating on an interior surface of the bottom wall and the four side walls. 9. The container of claim 1, wherein each hinged connection comprises a fold. 10. The container of claim 1, wherein each of the hinged connections and the arched elongate hinge is substantially continuous between the respective side walls and bottom wall. 11. The container of claim 1 further comprising an adhesive disposed on an exterior surface of at least one of the wall panels, wherein the adhesive is in a position so as to engage another one of the wall panels when the container is in the collapsed position, a reinforcement flap disposed along a top edge of at least one of the side walls, and a ridge disposed adjacent the top edge. 12. A collapsible container, comprising: a bottom wall having four peripheral edges; a side wall articulably connected to each peripheral edge of the bottom wall; each side wall articulably connected to an adjacent side wall along a corner thereof; and a diagonal fold defined in each of two opposing side walls and the bottom wall; wherein each of the corners is arched along a length thereof, and wherein the side walls and the bottom wall articulate at the respective folds, the peripheral edges, and the corners between a substantially flat collapsed state and an expanded state defining four side walls, a bottom wall, and an opening opposite the bottom wall, and wherein the sidewalls are locked into the expanded position as the diagonal fold moves out of substantially linear alignment with respect to the peripheral edges into the expanded position. 13. A collapsible container having a collapsed position and an expanded position, comprising: a bottom wall having four peripheral edges; a side wall articulably connected to each peripheral edge of the bottom wall; each side wall articulably connected to each adjacent side wall along a vertical corner thereof; and a diagonal fold defined in each of two opposing side walls and the bottom wall and creating a fold line, wherein each of the vertical corners is curved and causes the two opposing sidewalls to bulge convexly outwardly at least partially along the diagonal fold line, whereby a popping feel occurs as the collapsible container moves into the expanded position. 14. The collapsible container of claim 13, wherein an over-the-center latching action is created by the outwardly bulged opposing sidewalls. 15. The collapsible container of claim 13, wherein the collapsible container can be collapsed from the expanded position into the collapsed position by urging the diagonal fold lines back into linear alignment and toward an interior of the container.
