The invention relates to a collapsible transport and storage crate capable to be stacked. The sides (5) of the crate are provided with pins (13) sunk into connecting pieces (4) at the bottom of the crate. Upon folding down the sides they are lifted so that the pins (13) are pulled out of the connecting pieces (4) and are folded down hinged at them inward against the bottom. Thereby guide bosses (12) reach above the geometry of the folded-down crate and fix a crate located thereabove. In outfolded state tips (17) located on the upper edges of the sides can engage with pockets (15) located in the bottom of a crate thereabove and thereby fix said crate in lateral direction.

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. Anchor pins depend from the upper ends of the front and rear panels and are nested with upwardly opening slotted anchor brackets when in an upright position for interlocking opposite ends of the panels with the end assemblies.

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.

A collapsible bin comprising a generally rectangular bottom wall and four side walls is provided. The bottom wall has an upstanding U-shaped support element at each corner thereof. The side walls are arranged into first and second pairs. Each pair of side walls is pivotally mounted and supported by the U-shaped support elements. The side walls are collapsible from an upright position to a position on the bottom wall to provide a storage configuration of relatively small size. Latch means are provided to secure the side walls in an upright position.

A collapsible container with four side panels (15, 16, 17, 18) all at least semi-permanently connected to a base (10) by links (11, 41) allowing the panels (15, 16, 17, 18) to be moved between an upstanding condition on the base (1) where they are retained by engagement of bottom panel flanges (40) with channels (13, 14) on the base (10) and can be coupled by coupling means (19, 23) releasably secured by securing means (21, 22) to a collapsed condition by folding down the pannels (15, 16, 17, 18) into an overlying relationship. The link means (FIGS. 4-6) allowing the panels to move normally to their plane to disengage the flanges with the channels and then to pivot inwards to a horizontal position.
