In various embodiments, the side panels and base panel are affixed together using a live hinge. The tote container further operates to allow a user to apply labels forwardly and rearwardly on the container within a recess adapted for that purpose.

A pallet structure includes a positioning mechanism is provided. The positioning mechanism includes an engaging element disposed on a sloping edge and adapted to be engaged with slits formed on the inclined surface of a vehicle. A coil spring is connected between the engaging element and the sloping edge and biasing the engaging element to protrude outward from an outer surface of the sloping edge. A retaining element is disposed between an inner surface of the sloping edge and a bottom deck board of the pallet and configured to retain the engaging element to move between an engaging position and a disengaging position. The protruding end of the engaging element is protruded outward from the outer surface of the sloping edge in the engaging position, and the protruding end of the engaging element is not protruded from the outer surface of the sloping edge in the disengaging position.

An assembled plastic pallet is provided in the disclosure, which includes a panel and a plurality of support legs detachably arranged at a lower side of the panel. A metal reinforcement is embedded in the panel, each of the plurality of support legs is in a cuboid, four sides of each of the plurality of support legs is recessed inward to form a first groove, four sides of each of the plurality of support legs is formed with a reinforcing rib, and the reinforcing rib is smoothly transitioned to a bottom of the first groove with an arc. An assembled plastic pallet provided in this disclosure can be freely assembled as required and has high bearing capacity.

A packaging and shipping system for dry charged batteries. The packaging system includes a shipping crate having a lower section that defines an open interior. The open interior is sized to receive a dry charged battery and a plurality of electrolyte bottles. Each of the electrolyte bottles contains a volume of electrolyte sufficient to fill one of the individual cells of the dry charged battery. Each of the electrolyte bottles are separately packaged and positioned within the open interior of the shipping crate. Upon reaching the desired destination, the shipping crate can be stored. When the dry charged battery is to be placed into use, the shipping crate is opened and the individual cells of the dry charged battery are filled with electrolyte from the plurality of electrolyte bottles. Once the dry charged battery has been activated, the empty electrolyte bottles can be placed back into the shipping crate and returned for recycling.

Described is a pallet including a base having a length extending between a first end and a second end opposite the first end and a width transverse to the length; and a cage removably coupled to the base.

A pallet comprising at least three upper carrier plates (3) and at least three carrier supports (5), in which the bottom of each upper carrier plate (3) is provided with first snapping portions (11) in an array manner, the top of each carrier support (5) is provided with first snapping grooves (4), and the upper carrier plates (3) are snapped with the first snapping grooves (4) on the top of the carrier supports (5) through the first snapping portions (11), and which reduces space occupation and facilitates storage and transportation.

A collapsible crate includes a structural base and at least one collapsible corner post assembly coupled to the base. The corner post assembly includes supports configured to provide lateral protection to a payload in the crate. The corner post assembly is moveable between an upright position and a collapsed position. The crate can further be stackable and/or returnable.
