Abstract: A container comprises a rectangular top, bottom and sides. The sides each have two ends which are normally vertical. There is a hinge generally adjacent the bottom and one side permitting the one side to pivot outwardly. There is an angle section with an outwardly directed flange near each end of the one side and channel sections with inwardly directed flanges on the ends of the two other sides adjacent ends of the one side. The angle sections are engageable with the channel sections to constrain outward movement of the one side about the hinge. A latch constrains inward movement of the one side when the latch is engaged. A mechanism can deflect the outwardly directed flanges to permit the one side to pivot outwardly about the hinge for loading and unloading the container.
