A foldable tray comprises a baseplate, and a first side plate and a second side plate symmetrically arranged on the baseplate, both hingedly connected to the baseplate, and lie on the baseplate after being folded, and are height-adjustable side plates. An extension side plate that can be stretched out from the side plate is arranged at the top of the first and second side plates. The stretching height of the extension side plate is controlled by a prepositioning apparatus arranged in the first and second side plates. A side plate folding lock is arranged on the first and second side plates. The tray comprises roller shutter side plates symmetrically arranged on the baseplate and rolled in roller shutter storage apparatuses located in the baseplate, and can be pulled out under the action of external force. When the external force disappears, the roller shutter side plates can automatically retract.

An apparatus is provided for a collapsible product display container that may be shipped or stored in two main pieces, but which may be assembled at the point of sale by reversible attachment of four side walls to a pallet bottom. The four side walls are hingedly interconnected to each other and are attachable to the pallet bottom in an upright vertical relationship without bolts, screws, or other separate hardware. The container further comprises an advertisement display case that is connected to the back side wall by a hinge and may be moved into a vertical planar alignment above the back side wall of the container by hinging mechanism for marketing purposes.

A foldable crate includes a base having a front end and a rear end and a pair of end gates, wherein an end gate is rotatably attached to each end of the base. Each end gate includes a cap attached adjacent to one end of each post of the end gate and a knob is attached adjacent to the opposing end of each post. A skid shoe is attached to the bottom of each corner of the base, wherein each skid shoe includes a socket for receiving the knob or cap of the corresponding end gate of an adjacent foldable crate when a plurality of foldable crates are stacked.

A collapsible crate for transporting goods, the crate having an upstanding wall, at least a portion of which is movable, locating feature and releasable locking feature for releasably securing the movable wall portion relative to the crate, wherein the locating feature has a projection receivable within a recess or aperture to align, in use, the movable wall portion relative to the crate such that the movable wall portion is releasably securable by the locking feature.

A shipping container is coated, at least in part, with a protective polymer coating. Commercial shipping containers may be handled roughly, so damage is common especially with plastic containers. The protective coating improves the durability, scuff and chip resistance to make the container more safe for long life and use.

Described herein are collapsible containers for transportation of cargo, and methods of using them. The containers may include textured bottom surfaces to facilitate positive engagement with a conveyor. In some embodiments, the containers include secure locking mechanisms that prevent inadvertent unlocking while also permitting one-handed operation. In some embodiments, the containers include adapters to facilitate discharge of liquid cargo.

This invention discloses a collapsible container, comprising a base and two pairs of opposite side walls. The side walls are provided with one or more movable portions extending from the bottom of the side walls. The base is provided with one or more opening pockets, wherein the side walls are disposed in the corresponding opening pockets on the base via the movable portions. A hinge device is provided between the movable portions and the opening pockets. The hinge device comprises: hinge holes provided in the movable portions of the side walls; a guiding device provided in the opening pockets of the base; and a connecter provided with hinge pins and a sliding device to be engaged with the guiding device. The sliding device of the connecter is movable up and down in vertical direction along the guiding device in the opening pockets. The hinge pins are disposed in the hinge holes and are rotable around the hinge pins. When folded, the side walls of the collapsible container according to this invention will not inclined relative to the base. In addition, the collapsible container of the invention can be detached or folded in any consequences without tool.

This invention relates to a collapsible container and more particularly, but not exclusively, to a collapsible container for use in packaging and transportation. The collapsible container includes a number of panels each having a panel body, with elongate tubular members secured to edges of the bodies. Each of the tubular members has at least one recessed section that forms interlocking engagement means.

Systems and methods are disclosed for containers having mechanical secured door indicators. In one embodiment, an example container may include a first container wall, a second container wall, a third container wall, and a fourth container wall configured to move from an open position to a closed positon. The fourth container wall may include a first portion coupled to the second container wall, and a second portion coupled to the third container wall, where the first portion and the second portion are coplanar when the fourth container wall is in the closed position. The foldable container may include a bottom container platform having a machine-readable code, and a pivotable arm configured to cover the machine-readable code when the fourth container wall is in the closed position, and to uncover the machine-readable code when the fourth container wall is not in the closed position.
