Abstract: A collapsible bulk shipping container comprising a pallet with a tray secured to it, the front wall of the tray having a flap at its mid-portion severed from the front wall and fastened down against the tray bottom, the flap edges providing spaced detents. A wall element has a back panel, two side panels and two partial front panels, and is resiliently urged to flat condition. When placed inwardly of the tray walls, the edges of the partial front wall panels engage the edges of the tray flaps, which thereby hold the wall element open, providing front entry for loading the container. A single front closure panel overlaps the partial front panels of the wall element, to close the entry, this panel extending between the tray walls and the partial front panels.
