Patent ID: 8381471

Claim:
A packaging box adapted to be formed with a size selected from different varying sizes comprising: a single piece of material having an outer surface including a plurality of box walls and a plurality of box edges defined by intersecting box walls, and an inner surface of cushioning material including a first linear array of pyramid structures such that each pyramid in the linear array has a 45 degree base and a 90 degree peak angle and shares one edge with a respective adjacent pyramid of the first linear array of pyramid structures; a second linear array of pyramid structures such that each pyramid in the linear array has a 45 degree base and a 90 degree peak angle and shares one edge with a respective adjacent pyramid of the second linear array of pyramid structures; a plurality of additional linear arrays of pyramid structures such that each pyramid in the plurality of linear arrays has a 45 degree base and a 90 degree peak angle and shares one edge with a respective adjacent pyramid of the plurality of additional linear arrays of pyramid structures; a first linear interface between the first linear array and said second linear array; a plurality of additional linear interfaces between said plurality of additional linear arrays; said plurality of box walls including a first score line along the first linear interface and a second score line along any of said plurality of additional linear interfaces, wherein each of the plurality of box edges is defined by one of the first linear interface and plurality of additional linear interfaces, wherein the location of the first and second score lines being selected based upon the desired size of the packaging box thereby permitting the size of said packaging box to be varied by the selection of linear interfaces serving as box edges; wherein when the packaging box is assembled, the packaging box has a plurality of inside corners, and each inside corner of the plurality of corners is formed by mating a surface of one pyramid structure of the first linear array, the second linear array or the plurality of additional linear arrays with a respective abutting surface of one of a respective pyramid structure of the first linear array, the second linear array or the plurality of additional linear arrays such that the peak of the one pyramid structure and the peak of the respective pyramid structure are aligned to form a peak of a larger linear array of pyramid structures, wherein the peak of the larger linear array is situated at an inside corner.
