Abstract
A wrap-around carrier with gusset panels connected to the bottom panel that automatically fold into their upright position when the bottom panel flaps are set up for locking engagement. The resulting upright portions of the gusset panels contact the bottom portion of adjacent articles in the carrier to prevent the articles from falling out through the ends of the carrier. The fold lines connecting the gusset panels to the side panels are angled back to lengthen these fold lines while cutouts in the gusset panels shorten the length of the other fold lines of the gusset panels. This increases the pulling power of the gusset panels while decreasing the bias force which must be overcome in order for the gusset panels to be folded into their upright position.
Claims8
A wrap-around carrier containing a plurality of articles, comprising:
- opposite side panels, each side panel being connected along an upper fold line to a top panel and along a lower fold line to a bottom panel flap, the bottom panel flaps being connected to each other to form the bottom panel of the carrier;
- a gusset panel connected to a portion of each end edge of the side panels along a first fold line and connected to each end edge of an adjacent bottom panel flap along a second fold line;
- each gusset panel having an intermediate diagonal fold line dividing the gusset panel into a first section extending between the intermediate fold line and said first fold line and a second portion extending between the intermediate fold line and said second fold line;
- each gusset panel including a cutout at which the first, second and intermediate fold lines terminate;
- the first fold line being longer than the second fold line;
- and
- the end edge portions of each side panel to which the first fold lines of the gusset panels are connected converging toward each other;
- each gusset panel being folded about its first, second and intermediate fold lines so that one face of the first gusset panel section is in contact with the adjacent side panel and a portion of the opposite face of the first gusset panel section is in contact with a portion of the second gusset panel section, another portion of the second gusset panel section extending upwardly from its associated bottom panel flap, whereby lower side portions of the articles adjacent the gusset panels contact both portions of the second gusset panel sections;
- at least a substantial portion of the cutout being located in the upwardly extending portion of the second gusset panel section.
A blank for forming a wrap-around carrier for packaging a plurality of articles, comprising:
- a top panel section connected along fold lines at opposite sides thereof to side panel sections;
- each side panel section connected along a fold line to a bottom panel flap, the bottom panel flaps being adapted to be connected to each other to form the bottom panel of a carrier formed from the blank;
- a gusset panel connected to a portion of each end edge of the side panels along a first fold line and connected to each end edge of an adjacent bottom panel flap along a second fold line;
- each gusset panel having an intermediate diagonal fold line dividing the gusset panel into a first section extending between the intermediate fold line and said first fold line and a second portion extending between the intermediate fold line and said second fold line;
- each gusset panel including a cutout at which the first, second and intermediate fold lines terminate;
- the first fold line being longer than the second fold line;
- and
- the end edge portions of each side panel to which the first fold lines of the gusset panels are connected converging toward each other;
- each gusset panel being adapted to be folded about its first, second and intermediate fold lines so that one face of the first gusset panel section is in contact with the adjacent side panel of a carrier formed from the blank and a portion of the opposite face of the first gusset panel section is in contact with a portion of the second gusset panel section, another portion of the second gusset panel section extending upwardly from its associated bottom panel flap, whereby lower side portions of articles in the carrier adjacent the gusset panels contact both portions of the second gusset panel sections and at least a substantial portion of the cutout being located in the upwardly extending portion of the second gusset panel section.
