Patent ID: 7775419

Claim:
A method of forming a non-disassembling intersecting partition matrix, said matrix comprising a plurality of first slotted partitions intersecting with a plurality of second slotted partitions, each of the first slotted partitions having a plurality of spaced first slots extending inwardly from a first edge of the first slotted partition, a plurality of rectangular notches aligned with said first slots and extending inwardly from a second edge of said first slotted partition opposite said first edge of said first slotted partition, one of said notches having a second slot extending inwardly from said rectangular notch and aligned with a corresponding first slot, wherein said first and second slots define a folding axis dividing said first slotted partition into a small portion and a large portion, each of said second slotted partitions having a plurality of slots extending inwardly from a first edge of the second slotted partition and a plurality of rectangular notches aligned with said slots of said second slotted partition and extending inwardly from a second edge of said second slotted partition opposite said first edge of said second slotted partition, said method comprising the steps of: engaging said slots of said second slotted partitions with said first slots of said first slotted partitions at intersections to form the matrix; folding each of the first slotted partitions along its folding axis; attaching the small portion of the first slotted partition to the second slotted partition to permanently secure the intersecting partitions in a non-disassembling relationship.
