Abstract
Abstract A double thickness improved carton suspension including a die-cut hinged section formed in a panel of the carton with a flap hingedly attached along one edge of the carton having a die-cut tab connected along its outer edge so that when the flap is folded underneath and in overlapping relationship with the carton panel the tab and the die-cut section may be moved together into an upright position normal to the plane of the carton panel so that the carton may be suspended through the use of two cooperating apertures in both the tab and the die-cut section.

Claim 1
Independent Claim
208 words
A carton suspension formed integrally with a paperboard blank adapted to be folded into a rectangular paperboard carton, said blank comprising four adjacent panels adapted to be folded to form top, bottom and side wall panels of the carton, panels connected to said rectangular panels and adapted to be folded as at least a back panel for said carton; said suspension comprising: a die-cut section formed in said top panel and positioned within the border of said top panel, said section connected to said top panel along a first fold line extending parallel to said back panel of said carton; a spacing flap hingedly attached to said top panel by a second fold line parallel to said first fold line and positioned along the exposed edge of said top panel opposite said back panel; reinforcing means hingedly attached along a third hinge line to said flap, said reinforcing means being formed in shape substantially similar to said die-cut section, and said third fold line being spaced from second fold line a distance substantially equal to the spacing between said first and second fold lines; and said die cut section and said reinforcing means having formed therein apertures which when folded together are of substantially similar shape and size.
