Claim 9

The folder recited in claim 7, each of said notches comprising a pair of closely spaced lines being cut into the top surface of said first major wall but not through said first major wall, the portion of said first major wall top surface between said lines being compressed thereby forming a depression in said first major wall top surface.

Claim 10

The folder recited in claim 1, the line of fold between said first and second inner flaps being engageable with the line of fold between said second major wall and said outer flaps.

Claim 11

The folder recited in claim 1, the fold line foldably connecting each of said outer flaps to said second major wall being scored such that each of said outer flaps tears away from said second major wall when pulled back.

Claim 12

A cushioned shipping folder formed from a unitary blank of foldable paperboard or the like, comprising: first and second major parallel walls and first and second minor parallel walls foldably interconnected to form a tubular structure, said first and second major parallel walls being rectangular in shape, said first major wall being greater in length than said second major wall; a closure and protecting structure for each end of said tubular structure including first and second flaps foldably connected to each other along a straight fold line extending the entire length of said first and second flaps, said first and second flaps being rectangular in shape and coextensive in length with each other and with the width or shorter dimension of said first major wall, said first flap being foldably connected to said first major parallel wall along a straight fold line extending along the entire width or shorter dimension of said first major wall, at least a portion of said first flap being folded obliquely with respect to said first major wall, said second flap being folded to a position generally perpendicular to said first major wall, said first flap portion, said second flap and a portion of said first major wall forming a uniformly shaped air cushion extending across the entire width of said first major wall, said closure and protecting structure further comprising an additional fold line being formed in said first inner flap thereby dividing said first inner flap into a first and a second section, said first inner flap first section being folded obliquely with respect to said first major wall, the fold line between said first inner flap first and second sections being engageable with the line of fold between said outer flap and said second major wall, said first inner flap second section being folded to a position in facing relationship with said second major wall, thereby forming a trapezoidally shaped bumper.

Claim 13

A cushioned shipping folder formed from a unitary blank of foldable paperboard or the like, comprising: first and second major parallel walls and first and second minor parallel walls foldably interconnected to form a tubular structure, said first and second major parallel walls being rectangular in shape, said first major wall being greater in length than said second major wall; a closure and protecting structure for each end of said tubular structure including first and second flaps foldably connected to each other along a straight fold line extending the entire length of said first and second flaps, said first and second flaps being rectangular in shape and coextensive in length with each other and with the width or shorter dimension of said first major wall, said first flap being foldably connected to said first major parallel wall along a straight fold line extending along the entire width or shorter dimension of said first major wall, at least a portion of said first flap being folded obliquely with respect to said first major wall, said second flap being folded to a position generally perpendicular to said first major wall, said first flap portion, said second flap and a portion of said first major wall forming a uniformly shaped air cushion extending across the entire width of said first major wall, said closure and protecting structure further comprising an additional fold line being formed in said first inner flap thereby dividing said first inner flap into a first and a second section, said first inner flap first section being folded obliquely with respect to said first major wall, the fold line between said first inner flap first and second sections being engageable with the line of fold between said outer flap and said second major wall, said first inner flap second section being folded to a position in facing relationship with said second major wall, thereby forming a trapezoidally shaped bumper.

Claim 14

A cushioned shipping folder formed from a unitary blank of foldable paperboard or the like, comprising: first and second major parallel walls and first and second minor parallel walls foldably interconnected to form a tubular structure, said first and second major parallel walls being rectangular in shape, said first major wall being greater in length than said second major wall; a closure and protecting structure for each end of said tubular structure including first and second flaps foldably connected to each other along a straight fold line extending the entire length of said first and second flaps, said first and second flaps being rectangular in shape and coextensive in length with each other and with the width or shorter dimension of said first major wall, said first flap being foldably connected to said first major parallel wall along a straight fold line extending along the entire width or shorter dimension of said first major wall, at least a portion of said first flap being folded obliquely with respect to said first major wall, said second flap being folded to a position generally perpendicular to said first major wall, said first flap portion, said second flap and a portion of said first major wall forming a uniformly shaped air cushion extending across the entire width of said first major wall, said closure and protecting structure further comprising an additional fold line being formed in said first inner flap thereby dividing said first inner flap into a first and second section, said first inner flap first section being folded obliquely with respect to said first major wall, said first inner flap second section being folded to a position in facing relationship with said second major wall, the fold line between said first inner flap first and second section being engageable with the end edge of said second major wall.
