ABSTRACT:
An enclosed carrier having spaced handle openings in the top panel. The top panel is formed from two overlapping flaps, each of which has a folded-over edge portion adhered to itself. The folded-over edge portions overlie each other to form the strap portion of the handle extending between the handle openings, with the folds of the edge portions being aligned with the inner edges of the handle openings. In one embodiment the handle strap comprises a four-ply layer and in another embodiment it comprises a three-ply layer. The folded-over edge portions of the top flaps may be weakened at their intersection with the fold lines of end panel flaps to enable the end panel flaps to be readily folded into place.
