Abstract: A container having a base portion including four vertical square tube members with one tube member at each corner of the base portion, and bottom surfaces of the base portion sloping inwardly to an elongated opening along the bottom of the base portion that is closed off by a trap door. The upper portion of the container is formed with four additional vertical square tube members that provide support for the upper sides of the container, with the upper square tube members and sides of the container being pinned to the lower vertical square tube members such that the four sides of the container can be folded downwardly onto the base portion when the container is emptied. When folded to an upright position the four upper sides interlock and are held in position by pressure from within the container.
