Collapsible protective carton with interior cradle

Claim 2

A collapsible carton of substantially rectangular cross section including outer walls and a product cradle of substantially rectangular cross section supported within said outer walls, said carton being formed from at least one blank comprising adjacent parallel panels separated by parallel longitudinal fold lines and including at least four successive outer wall panels, two of said outer wall panels forming respective top and bottom panels characterized in that said cradle divides the assembled carton into respective upper, central, and lower compartments and is separated from said top and bottom panels of said carton by stand-off tabs formed by portions of at least two opposite walls of said cradle which extend beyond the periphery of said cradle, at least said central compartment being adapted to hold a product and said upper and lower compartments providing top and bottom protection for the contents of said cradle and additional usable storage space.

Claim 3

A collapsible carton in accordance with claim 1 further characterized in that a pair of diagonal web members extend across both ends of said cradle between said cradle and the respective ends of the assembled carton, both to position the contents of said cradle within said carton and to provide end protection for the contents of said cradle.

Claim 4

A collapsible carton in accordance with claim 2 further characterized in that a blank includes a succession of at least five parallel cradle panels separated by respective longitudinal fold lines, a first of said cradle panels is a lap panel for assembly in a position adjacent to one of said outer wall panels, a second of said cradle panels is a product supporting panel adjacent to said first cradle panel, a third of said cradle panels is a lap panel adjacent to said second cradle panel, a fourth of said cradle panels is a product supporting panel adjacent to said third cradle panel, the fifth of said cradle panels is a lap panel adjacent to said fourth cradle panel, one of said second and fourth cradle panels has a pair of lateral cut-outs running parallel to each other and substantially perpendicular to said fold lines at predetermined distances from opposite ends of the panel, and the portions of said fold lines extending from each of said lateral cut-outs to the ends of the panel containing them are displaced in the same direction from but are substantially parallel to the remaining portions of said fold lines, enabling the end portions of the panel to form said diagonal web members at both ends of the carton in its assembled form.

Claim 5

A collapsible carton in accordance with claim 3 further characterized in that said outer wall panels and said cradle panels are all formed from a single blank.

Claim 6

A collapsible carton in accordance with claim 2 further characterized in that a blank includes a succession of at least five parallel cradle panels separated by respective longitudinal fold lines, a first of said cradle panels is a lap panel for assembly in a position adjacent to one of said outer wall panels, a second of said cradle panels is a product supporting panel adjacent to said first cradle panel, a third of said cradle panels is a lap panel adjacent to said second cradle panel, a fourth of said cradle panels is a product supporting panel adjacent to said third cradle panel, the fifth of said cradle panels is a lap panel adjacent to said fourth cradle panel, said second cradle panel contains longitudinal cut-outs extending parallel and adjacent to the fold lines between it and said first and third cradle panels, portions of both fold lines of said second cradle panel extending between said longitudinal cut-outs are displaced in opposite directions from but are parallel to the remaining portions of said fold lines, making the width of said second cradle panel defined by said longitudinal cut-outs less than the width of the corresponding outer wall panels and spacing said second cradle panel from one of the outer wall panels when the carton is in its assembled form, said fourth cradle panel contains longitudinal cut-outs extending parallel and adjacent to the fold lines between it and said third and fifth cradle panels, portions of at least one of the fold lines of said fourth cradle panel extending between said linear cut-outs are displaced from but are parallel to the remaining portions of said fold line, spacing said fourth cradle panel from one of the outer wall panels when the carton is in its assembled form, said second and fourth cradle panels define said upper, central, and lower compartments within the carton in its assembled form, one of said second and fourth cradle panels has a pair of lateral cut-outs running parallel to each other and substantially perpendicular to said fold lines at predetermined distances from opposite ends of the panel, and the portions of said fold lines extending from each of said lateral cut-outs to the ends of the panel containing them are displaced in the same direction from but are substantially parallel to the remaining portions of said fold lines, enabling the end portions of the panel to form said diagonal web members at both ends of the carton in its assembled form.

Claim 7

A collapsible carton in accordance with claim 5 further characterized in that said outer wall panels and said cradle panels are all formed from a single blank.

Claim 8

A collapsible carton in accordance with claim 5 further characterized in that said second cradle panel contains said pair of lateral cutouts.

Claim 9

A collapsible carton in accordance with claim 7 further characterized in that the fold lines adjacent said outer wall panels are formed by creasing.

Claim 10

A collapsible carton in accordance with claim 7 further characterized in that the fold lines adjacent said outer wall panels are formed by creasing and the remaining fold lines are formed by intermittent piercing.

Claim 11

A collapsible carton in accordance with claim 1 further characterized in that a blank includes a succession of at least five parallel cradle panels separated by respective longitudinal fold lines, a first of said cradle panels is a lap panel for assembly in a position adjacent to one of said outer wall panels, a second of said cradle panels is a product supporting panel adjacent to said first cradle panel, a third of said cradle panels is a lap panel adjacent to said second cradle panel, a fourth of said cradle panels is a product supporting panel adjacent to said third cradle panel, the fifth of said cradle panels is a lap panel adjacent to said fourth cradle panel, said second cradle panel contains longitudinal cut-outs extending parallel and adjacent to the fold lines between it and said first and third cradle panels, portions of both fold lines of said second cradle panel extending between said longitudinal cut-outs are displaced in opposite directions from but are parallel to the remaining portions of said fold lines, making the width of said second cradle panel defined by said longitudinal cut-outs less than the width of the corresponding outer wall panels and spacing said second cradle panel from one of the outer wall panels when the carton is in its assembled form, said fourth cradle panel contains longitudinal cut-outs extending parallel and adjacent to the fold lines between it and said third and fifth cradle panels, portions of at least one of the fold lines of said fourth cradle panel extending between said linear cut-outs are displaced from but are parallel to the remaining portions of said fold line, spacing said fourth cradle panel from one of the outer wall panels when the carton is in its assembled form, and said second and fourth cradle panels define said upper, central, and lower compartments within the carton in its assembled form.

Claim 12

A collapsible carton in accordance with claim 3 further characterized in that said outer wall panels and said cradle panels are all formed from a single blank.
