Abstract: A rigid collapsible container has a base with upstanding interconnected lower corner posts mounting a deck. A pair of end assemblies with upper corner posts overlie the lower corner posts, have a normal upright position and are pivotal to a horizontal position. Each upper corner post has a depending connector which extends into a lower corner post and is pivotally mounted thereon. Each lower corner post has an upwardly opening slot terminating in a cam detent notch. A transverse lock pin on each connector is supportably nested within a slot to maintain the end assemblies upright. The end assemblies may be successively pivoted inwardly to a collapsed position with the lock pins riding against the cam notches. Spaced front and rear panels are arranged between the end assemblies and pivoted upon the base and include retractable latches which interlock with the upper corner posts. The front and rear panels are successively collapsible upon the deck and the end assemblies are successively collapsible thereover.
