  • Patent number: 5335774
    Abstract: This invention relates to a can carrier for forming into a package and carrying one or more cans, normally six cans to form a six-pack. The can carrier is primarily formed of a sheet of readly foldable and deformable material including paperboard. For each can, the sheet is provided with a pair of cutouts defining foldable flaps. The flaps are foldable beneath the sheet with each pair of flaps being remote from one another. The result is that the connection between each flap and the sheet provides two layers of materials which are engagable beneath a can chime to interlock the can with the can carrier. The folded connection between each flap and the sheet may be reinforced by stretchable self shrinking glue disposed generally in the apex of the connection between each flap and the under side of the sheet. Another form of flap reinforcement is the bonding of a synthetic thread to the under side of the sheet and the flaps with the thread extending longitudinally of the sheets and the flaps.

  • Patent number: 5328024
    Abstract: A bottle carrier of the type employing tabs surrounding bottle neck openings to support the underside of bottle flanges. The carrier is comprised of an inner clip member and an outer shroud, each having aligned bottle neck openings and tabs. The outer shroud incorporates side panels which fold around adjacent bottles and are adhered to the inner face of the end panels. The side panels are moved into place by the pulling action of gusset panels as the latter are folded into position at the inner face of the end panels. The outermost bottle support tabs are of greater height than the innermost tabs to accommodate bowing of the carrier during lifting, and the other tabs have angled edges adapted to contact the bottle flanges when the carrier is lifted. The inner clip includes short flaps underlying the side and end flaps of the outer shroud.

  • Patent number: 5326024
    Abstract: A carton for packaging pourable material. Upper end panel sections are connected by gussets to sloped upper side panel sections, and the latter are connected by overlapping horizontal flaps. Separation of an end tear strip portion of the horizontal flaps allows an upper end panel section to be folded out to form a pouring spout configuration. The tab remaining after separation of the tear strip portion is inserted in a slit in the upper end panel section to hold the section in place after being reclosed.

  • Patent number: 5316207
    Abstract: A container formed by wrapping a slotted flexible sheet about rigid end panels having projections that extend through the slots. The projections include stacking projections which engage recesses in the end panels of adjacent stacked containers and support projections at the corners. The support projections engage each other when the containers are stacked to provide resistance to lateral loading. At least one end of the flexible sheet terminates in the top panel and engages a wedge-shaped projection on the end panels to lock that end of the sheet in place. The other end may be similarly locked in place or may overlap the first end and be held in place by a tab and slot arrangement. Alternatively, the other end portion of the sheet may include a lid which is held in place by mechanical tabs, while intermediate edges spaced from the end engage the wedge-shaped projections.

  • Patent number: 5311984
    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.

  • Patent number: 5310050
    Abstract: Means for holding the bottoms of petaloid shaped bottles in place in a wrap-around carrier. Side panel apertures include flaps connected to the side panel by fold lines which are inwardly curved at their upper portions. The lower portions of each pair of flaps extend toward each other so as to engage one or more support feet of the adjacent bottle and be forced out from the side panel thereby. The curved portion of the fold lines biases the flaps against the support feet, regardless of which portion of the feet engage the flaps, to assist in holding the bottles in place within the carrier. Fold lines extending from the flap edges to the flap fold lines and hook-shaped slits at the upper ends of the flaps allow the side flaps to flex lengthwise.

  • Patent number: 5307986
    Abstract: An article carrier which permits ice to be added to the carrier after removing the top to cool the contents. The carrier is formed from a paperboard blank having a waterproof interior surface. The end and side panels are connected by gusset panels, the end portions of which are adapted to be in nonadhered face-to-face relationship. When the top panel of the carrier is removed, these portions of the gusset panels are relaxed, allowing the side and end panels to pivot out about their foldable connection to the bottom panel for a limited distance to expand the interior of the carrier while maintaining the carrier in watertight condition.
