Patent ID: 7114618

Claim:
A unitary foam packing element, comprising: a planar piece of foam, said piece of foam being precut with a plurality of score lines; said score lines define a first planar portion and a second planar portion, said score lines enabling said first planar portion to be folded over onto said second planar portion to thereby form a flat cavity having a first predetermined perimeter defined between said first planar portion and said second planar portion; and said score lines further define an end panel adjacent the second planar portion, said end panel being adapted to be folded along a respective one of said score lines so as to form a first end wall of said flat cavity; wherein, when said first planar portion is folded over onto said second planar portion, the score lines further define one or more openings in the single planar piece of foam; and wherein the score lines further define one or more insert pieces that can be separated from the single planar piece of foam and inserted into the one or more openings to thereby reduce an effective size of the flat cavity and define a second predetermined perimeter smaller than said first predetermined perimeter.
