Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
175 words
A blank for forming a prismatic carton having a pentagonal cross section which comprises, a central panel, a pair of inner wall panels foldably attached to opposite sides of said central panel along score lines, an outer wall panel foldably attached to the outer edge of each of said inner wall panels, a pair of opposed inner end flaps foldably connected to opposite ends of said central panel along substantially parallel crease lines extending between said inner wall panels, an opposed pair of outer end flaps foldably connected to opposite ends of each of said outer wall panels along substantially parallel crease lines, said blank being substantially symmetrical about a plane extending normal to and bisecting said central panel, said crease lines extending between said central panel and said inner end flaps and the crease lines between said outer wall panels and said outer end flaps being inwardly offset with respect to outer edges of said inner wall panels, and die-cut sections extending from said crease lines to edge portions of said inner wall panels.
Claim 2
Dependent Claim
175 words
A blank for forming a prismatic carton having a pentagonal cross section which comprises, a central panel, a pair of inner wall panels foldably attached to opposite sides of said central panel along score lines, an outer wall panel foldably attached to the outer edge of each of said inner wall panels, a pair of opposed inner end flaps foldably connected to opposite ends of said central panel along substantially parallel crease lines extending between said inner wall panels, an opposed pair of outer end flaps foldably connected to opposite ends of each of said outer wall panels along substantially parallel crease lines, said blank being substantially symmetrical about a plane extending normal to and bisecting said central panel, said crease lines extending between said central panel and said inner end flaps and the crease lines between said outer wall panels and said outer end flaps being inwardly offset with respect to outer edges of said inner wall panels, and die-cut sections extending from said crease lines to edge portions of said inner wall panels.
Claim 3
Dependent Claim
28 words
A blank for forming a prismatic carton having a pentagonal cross section as defined in claim 1 wherein said inner end flaps are formed with a hexagonal configuration.
Claim 4
Dependent Claim
31 words
A blank for forming a prismatic carton having a pentagonal cross section as defined in claim 1 wherein a portion of said central panel is removed to form a window portion.
Claim 5
Dependent Claim
44 words
A blank for forming a prismatic carton having a pentagonal cross section as defined in claim 1 wherein a glue flap extends from an outer edge of one of said outer wall panels for cooperative engagement with the other of said outer wall panels.
Claim 6
Dependent Claim
110 words
A prismatic carton construction having a pentagonal cross section which comprises, a central panel, a pair of outwardly diverging wall panels extending from opposed sides of said central panel, a pair of converging wall panels with one integrally extending from each of said diverging wall panels and converging in abutting relationship at their outer ends, an inner end flap extending from each end of said central panel substantially normal thereto and having outer edges in abutting relationship with inner surfaces of said diverging and converging wall panels, and a pair of outer end flaps overlying each inner end flap and sealingly closing opposite end portions of said prismatic carton structure.
Claim 7
Dependent Claim
110 words
A prismatic carton construction having a pentagonal cross section which comprises, a central panel, a pair of outwardly diverging wall panels extending from opposed sides of said central panel, a pair of converging wall panels with one integrally extending from each of said diverging wall panels and converging in abutting relationship at their outer ends, an inner end flap extending from each end of said central panel substantially normal thereto and having outer edges in abutting relationship with inner surfaces of said diverging and converging wall panels, and a pair of outer end flaps overlying each inner end flap and sealingly closing opposite end portions of said prismatic carton structure.
Claim 8
Dependent Claim
37 words
A prismatic carton construction as defined in claim 5 wherein said outer end flaps are foldably attached to said converging wall portions and abut one another along a plane extending normal to and bisecting said central panel.
Claim 9
Dependent Claim
44 words
A prismatic carton as defined in claim 5 wherein a glue flap extends from an outer edge of one of said converging wall panels and is secured to an edge portion of the other of said converging wall panels along their line of abutment.
Claim 10
Dependent Claim
30 words
A prismatic carton as defined in claim 5 wherein said inner end flaps have a hexagonal configuration which complements and supports adjacent portions of said diverging and converging wall portions.
Claim 11
Dependent Claim
47 words
A prismatic carton as defined in claim 5 wherein said inner end flaps are inwardly offset with respect to said diverging wall panels, and the outer surface of said outer end flaps lie substantially within a plane passing through the outer edges of said diverging wall panels.
