    Abstract: A collapsible delivery container having hinged legs that fold inwardly to permit the top of the container to collapse toward the bottom of the container. The container is configured to permit it to be collapsed one side at a time. The container includes a handle on each side that extends between the intermediate hinges of the corresponding legs. The handle is configured to be accessible when the container is collapsed, yet out of the way when the container is raised. The container further includes a nesting structure that, among other things, retains the first collapsed side in proper alignment while the second side is collapsed. The nesting structure also provides a force path from the top of the container to base so that the hinges are not required to bear the weight of stacked containers. The container preferably includes a lift assist mechanism that bears some of the weight of the container as it is collapsed and raised.
