Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
230 words
A cushioned shipping folder formed from a unitary blank of foldable paperboard or the like, comprising: a. opposed pairs of major and minor parallel walls foldably interconnected to form a tubular structure; b. an outer closure flap foldably connected to one of said parallel walls and secured to an adjacent parallel wall of said tubular structure; c. a closure structure for each end of said tubular structure, said structure comprising: i. a pair of first and second inner flaps foldably connected to each other with one of said flaps being foldably connected adjacent to one end of said major parallel walls: A. said first inner flap being folded to a position in facing relationship to said one major parallel wall; B. said second inner flap being folded perpendicularly with respect to said first inner flap and said one major parallel wall; ii. a pair of first and second outer flaps foldably connected to each other with one of said outer flaps being foldably connected to one end of the other of said major parallel walls: A. said first outer flap being folded to an oblique position in contact with edges of said inner flaps; B. said second outer flap being folded along and secured to the first of said major parallel walls; iii. said first and second pair of flaps defining a deformation resistant cell of generally triangular cross section.
