Abstract: A spacer device for a product employs a plurality of elongated first channel structures interconnected by a plurality of interconnecting support structures. The first channel structures have a pair of sidewalls, a top wall, a bottom wall and a pair of endwalls defining a channel interior. The support structures interconnect the first channel structures at spaced locations to hold them in spaced apart relation to form a first lattice having a plurality of openings to permit air circulation. Preferably, a similar second lattice is employed and is inverted and joined with the first lattice to create an endless channel. The support structures on each of the lattices are positioned to enclose the channel interiors on the other of the lattices. The spacer device may also be configured as a container with the lattice openings eliminated so that the spacer device forms an enclosure to contain products. Foam or fluid may be used to fill the channel interiors, if desired.

Abstract: The invention is a pallet useful as a spacer with containers for heat transfer. The invention includes a plurality of longitudinal and lateral elongated U-shaped channel members having a bottom, sidewalls and flanges at the ends of sidewalls. Each of the members of one of the groups generally opposed to the members of the other group and at right angles to the other group with the bottom of each member of each group facing outward. Strengthening plates are disposed at the intersections of the members which are efficient in transferring thermal energy.
