Abstract: A nondisassembling partition assembly comprising a partition matrix made up of intersecting first and second slotted plastic partitions, each of the partitions having at least one slot. The slots of the partitions are engaged with each other at a plurality of intersections. The matrix is held together in a nondisassembling relationship by at least one parent weld formed by heating an edge of the partitions at one or more intersections with one or more heat sources until the intersecting partitions become molten, removing the heat source or sources from edge of the intersecting partitions and allowing the partitions to cool. The parent welds formed by this process permanently secure the partitions together in the nondisassembling relationship without the use of any material other than the partitions themselves.

Abstract: A container for holding product therein during shipment and comprises a body including a base, rigid side walls and a removable cover. The body has at least one open side and a first product grid is positioned in the body and forms a first plurality of generally horizontally disposed product bins. The product bins have outside open ends and are disposed such that the outside open ends face outwardly of an open side of the container for horizontally receiving a product to be shipped and for providing horizontal access to the product from a side of the container. A second plurality of bins is juxtaposed with the first plurality and flexible wall is positioned between the two bin pluralities to form end walls for the bins. The flexible end walls create an expansible bin. The container body also includes a mounting structure thereon for securing at least one additional rigid side wall to the body for forming a container body closed on all sides.
