Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 153 words
A two component shipping container for shipping refrigerated products comprising: a. an outer container product component formed from a scored and cut blank of paperboard or the like having a plurality of sidewalls hingedly connected to one another along fold lines; b. bottom closure flaps foldably attached to the lower edges of each of said outer container sidewalls for closing the entire bottom of said outer container; c. top closure flaps foldably attached to the upper edges of each of said outer container sidewalls and having their free edges spaced apart to leave a central opening in the top of said outer container; and d. an inner container refrigerant component formed from a cut and scored blank of paperboard or the like having a plurality of sidewalls with means attached thereto for maintaining the inner container under the central opening of the outer container anD spaced from the walls of said outer container.
Claim 2
Dependent Claim 153 words
A two component shipping container for shipping refrigerated products comprising: a. an outer container product component formed from a scored and cut blank of paperboard or the like having a plurality of sidewalls hingedly connected to one another along fold lines; b. bottom closure flaps foldably attached to the lower edges of each of said outer container sidewalls for closing the entire bottom of said outer container; c. top closure flaps foldably attached to the upper edges of each of said outer container sidewalls and having their free edges spaced apart to leave a central opening in the top of said outer container; and d. an inner container refrigerant component formed from a cut and scored blank of paperboard or the like having a plurality of sidewalls with means attached thereto for maintaining the inner container under the central opening of the outer container anD spaced from the walls of said outer container.
Claim 3
Dependent Claim 25 words
The shipping container of claim 1 wherein said spacing means comprises flaps foldably attached to the lower edges of each of said inner container sidewalls.
Claim 4
Dependent Claim 42 words
The shipping container of claim 2 wherein the top closure flaps attached to said outer container sidewalls each have means on the free edges thereof for securing the upper end of said inner container in spaced relation to said outer container sidewalls.
Claim 5
Dependent Claim 218 words
A two component shipping container for shipping refrigerated products comprising: a. an outer container formed from a scored and cut blank of paperboard or the like having a plurality of sidewalls hingedly connected to one another along fold lines; b. bottom closure flaps foldably attached to the lower edges of each of said outer container sidewalls; c. top closure flaps foldably attached to the upper edges of each of said outer container sidewalls; d. an inner container fitted inside of and spaced from the walls of said outer container; e. said inner container having a plurality of sidewalls hingedly connected to one another along fold lines, and means attached thereto for maintaining the inner container in spaced relation to the walls of said outer container; f. said spacing means comprising flaps foldably attached to the lower edges of each of said inner container sidewalls; g. the top closure flaps of said outer container each having means on the free edges thereof for securing the upper end of said inner container in spaced relation to said outer container sidewalls; and h. said securing means comprising locking flanges cut from the top closure flaps which tuck inside said inner container sidewalls to close the peripheral space around said inner container and leave open the upper end of said inner container.
Claim 6
Dependent Claim 218 words
A two component shipping container for shipping refrigerated products comprising: a. an outer container formed from a scored and cut blank of paperboard or the like having a plurality of sidewalls hingedly connected to one another along fold lines; b. bottom closure flaps foldably attached to the lower edges of each of said outer container sidewalls; c. top closure flaps foldably attached to the upper edges of each of said outer container sidewalls; d. an inner container fitted inside of and spaced from the walls of said outer container; e. said inner container having a plurality of sidewalls hingedly connected to one another along fold lines, and means attached thereto for maintaining the inner container in spaced relation to the walls of said outer container; f. said spacing means comprising flaps foldably attached to the lower edges of each of said inner container sidewalls; g. the top closure flaps of said outer container each having means on the free edges thereof for securing the upper end of said inner container in spaced relation to said outer container sidewalls; and h. said securing means comprising locking flanges cut from the top closure flaps which tuck inside said inner container sidewalls to close the peripheral space around said inner container and leave open the upper end of said inner container.
Claim 7
Dependent Claim 54 words
The shipping container of claim 4 wherein the locking flanges of each top closure flap are formed by a pair of cut lines which extend from the free edge of each top closure flap to a fold line lying perpendicular to said cut lines and substantially in the center of each top closure flap.
Claim 8
Dependent Claim 76 words
The shipping container of claim 5 wherein the locking flanges on alternate opposed pairs of said top closure flaps contain tab elements formed by the cut lines, and the locking flanges on the other pairs of said top closure flaps contain slot areas formed by the cut lines so that the adjacent tabs and slots may interlock with one another when the top closure flaps are folded to close the peripheral space around said inner container.
Claim 9
Dependent Claim 16 words
The shipping container of claim 6 wherein the outer container sidewalls are tapered throughout their length.
Claim 10
