A block assembly for connecting a first section and a second section of a load bearing assembly includes a male fitting and a female fitting. The male fitting includes a male fitting body and a projection extending from the male fitting body. The female fitting includes a female fitting body and defines a fitting cavity extending within an interior of the female fitting body. The male fitting couples with the female fitting by inserting the male fitting body within the fitting cavity and moving the male fitting body toward a base of the female fitting. The projection on the male fitting interacts with an interlocking joint on the female fitting to resist detachment of the male fitting with respect to the female fitting.

A system and method are provided for manufacturing a plastic pallet having a plurality of runner assemblies with embedded support structures. Each runner assembly may include a top runner board, a bottom runner board, and a plurality of support structures embedded into the top and bottom runner boards. The pallet may be manufactured using heat to at least partially penetrate and soften the runner boards, to soften the support structures, and to weld the support structures to the runner boards in an embedded manner.

An asymmetric mold core for forming curved floor openings in pallets is taught. The mold core contains: a base, the base attachable to a frame in a rotomold, a bottom section integral at a distal end to the base, the bottom section comprising a bottom convex curve having a bottom convex curve radius and a bottom convex curve rotational center, a top section integral at a distal end to the base, the top section comprising a top convex curve, the top convex curve having a top convex curve radius and a top convex curve rotational center, the top convex curve radius being different from the bottom convex curve radius and the top convex curve rational center differing from the bottom convex curve rotational center; a first side section, the first side section positioned and integral at a distal end to the base and positioned between and integral with the bottom section and the top section; a second side section the second side section positioned and integral at a distal end to the base and positioned between and integral with the bottom section and the top section, the second side section positioned parallel to the first side section; and a face.

The present invention provides a movable load bearing structure with a surface that includes antimicrobial agents capable of eliminating, preventing, retarding or minimizing the growth of microbes and also minimizing cross-contamination when the load bearing structure is being reused for cargoes that differ from a previously transported cargo, for example, different food types, such as poultry, fresh vegetables, and fresh fruit. The load bearing structure may be a dunnage platform or a container for storing and/or shipping cargo.

The present invention solves the above mentioned technical problems by providing a three dimensional molded shape suitable for use in the fabrication of a food tray, the molded shape comprising a molded pulp portion with side walls and a bottom wall comprising virgin or recycled cellulose fibers and a film laminate portion comprising a polyester film with an amorphous polyester heat seal layer.

A polymer composition comprising a blend of two or more high density polyethylenes: (A) a first high density polyethylene having a density of at least 940 kg/m.sup.3 and an MFR.sub.2 of 0.25 g/10 min or less; and (B)a second high density polyethylene having a density of at least 940 kg/m.sup.3 and an MFR.sub.2 of 1.0 g/10 min to 20 g/10 min; wherein said polymer composition has an MFR.sub.2 of 0.25 to 15 g/10 min and wherein the components (A) and (B) combined form at least 91 wt % of said polymer composition.

A method of manufacturing a pallet for use during manufacture of a printed circuit board assembly includes determining optimal solder flow for establishing connections between lead pins of a plurality of pin-through-hole components arranged on a circuit board, designing a pallet to include geometries configured to provide the optimal solder flow when the pallet, supporting the circuit board thereon, is passed through a wave solder machine, and creating the pallet based on the design. Pallets configured for optimal solder flow and methods of manufacturing printed circuit board assemblies using such pallet are also provided.

The inventors have discovered that certain hot melt adhesives can be used to form a stable stacked pallet that can limit the need for additional packaging materials e.g. inter-layer and pallet wrap.

Certain embodiments of the present disclosure describe a pallet assembly having a support assembly and a stringer. The support assembly includes a deck and a plurality of blocks that extend from the deck. The deck and the blocks are unitarily formed to create a contiguous outer shell that defines a common internal space that is filled with a support material. The blocks include extension portions that correspond to openings defined in the stringer. The extensions are received in a corresponding opening to attach the stringer to the support assembly.
