Abstract:
1. A packing material, comprising: a thin plastic bag; a plurality of compressible beads inside the thin plastic bag, wherein the pressure inside the bag is not greater than 14.4 pounds per square inch and is sufficiently lower than the ambient pressure outside the bag to maintain the beads in a non-free-flowing state; wherein the compressible beads are arranged so that the bag is generally flat, having a generally constant cross-sectional thickness with a first number of beads in cross-section, and with at least two parallel elongated linear troughs having a lesser cross-sectional thickness with fewer beads in cross-section while still having at least one bead in the cross-sectional thickness of the elongated troughs, and with said troughs separating said bag into at least first, second, and third areas; and a box having a rectangular bottom and rectangular left, right, front and rear sides projecting upwardly from the bottom along linear edges; wherein the second generally constant cross-sectional thickness area covers the bottom of the box, with the first and third generally constant cross-sectional thickness areas lying along the left and right sides of the box, and with the two parallel troughs lying along two of the linear edges.
