Abstract
Abstract A paperboard wrap-around article carrier which has end panels foldably connected to the top panel and to gusset panels. The gusset panels allow the end panels to be folded and maintained in a substantially vertical position. The end panels extend beyond the lowermost ends of the gusset panels so that the foldable connections between the gusset panels and the end panels is minimal, thus minimizing the cumulative memory of the fibers in the foldable connections to prevent the forces generated by the memory from unfolding the end panels and snapping them up out of place.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
240 words
In a paperboard wrap-around article carrier including a top panel having side edges and end edges, side panels having upper edges and end edges, the upper edges of the side panels being connected to the side edges of the top panel by fold lines, and a bottom panel connecting the side panels, the improvement comprising: end panels connected by fold lines to the end edges of the top panel, each end panel having an unconnected bottom edge and unconnected side edge portions adjacent the unconnected bottom edge; gusset panels connecting the end panels to the side panels; each gusset panel being connected by a first fold line to a portion of the associated side panel near the fold line connecting the side panel to the top panel; each gusset panel being connected by a second fold line to a portion of the associated end panel near the fold line connecting the end panel to the top panel; the second fold lines terminating in lowermost ends spaced a substantial distance from the bottom edge of the associated end panel; and each gusset panel further having a lower edge extending outwardly from the lowermost end of the associated second fold line to the adjacent end edge of the associated side panel; the second fold lines connecting the gusset panels to an end panel being spaced apart a distance less than the distance between the unconnected side edge portions of the end panel.
Claim 2
Dependent Claim
240 words
In a paperboard wrap-around article carrier including a top panel having side edges and end edges, side panels having upper edges and end edges, the upper edges of the side panels being connected to the side edges of the top panel by fold lines, and a bottom panel connecting the side panels, the improvement comprising: end panels connected by fold lines to the end edges of the top panel, each end panel having an unconnected bottom edge and unconnected side edge portions adjacent the unconnected bottom edge; gusset panels connecting the end panels to the side panels; each gusset panel being connected by a first fold line to a portion of the associated side panel near the fold line connecting the side panel to the top panel; each gusset panel being connected by a second fold line to a portion of the associated end panel near the fold line connecting the end panel to the top panel; the second fold lines terminating in lowermost ends spaced a substantial distance from the bottom edge of the associated end panel; and each gusset panel further having a lower edge extending outwardly from the lowermost end of the associated second fold line to the adjacent end edge of the associated side panel; the second fold lines connecting the gusset panels to an end panel being spaced apart a distance less than the distance between the unconnected side edge portions of the end panel.
Claim 3
Dependent Claim
33 words
In a paperboard wrap-around article carrier according to claim 1, wherein the distance between the unconnected edge portions of an end panel is substantially equal to the distance between the adjacent side panels.
Claim 4
Dependent Claim
34 words
In a paperboard wrap-around article carrier according to claim 1, wherein the second fold lines lie in a generally vertical plane taken through the fold lines connecting the side panels to the top panel.
Claim 5
Dependent Claim
92 words
In a paperboard wrap-around article carrier according to claim 1, wherein the force developed by the cumulative memory of the paperboard along the second fold lines connecting the gusset panels to the end panels is insufficient to pivot the end panels up about the fold lines connecting the end panels to the top panel, and wherein the length of the end panels is at least as great as one-half the height of the carrier and the length of the second fold lines is less than one-half the length of the end panels.
Claim 6
Dependent Claim
