  • Patent number: 7628311
    Abstract: A folded food carton is formed from a matable, lay flat blank for retaining, transporting and serving hot food such as pizza. The blank includes an arrangement of end panels, side panels and cover panels foldable relative to a bottom panel such that, in the erected carton, the cover panels overlap and are interlocked with the side panels by means of offset locking tabs. The end panels slant upwardly and inwardly from the bottom panel to add rigidity and save material for the carton. The side panels flare upwardly and outwardly from the bottom panel and extend above the cover panels to enhance stackability and prevent shifting of stacked cartons one on top of the other. Several methods of packaging pizza in the folded carton are disclosed.

  • Patent number: 6948651
    Abstract: An elongate blank for forming a tubular carton includes panels arranged in a row along the length of the blank. The panels are hingedly connected one to another in series. Each panel has a pair of opposed free end edges disposed generally along the length of the blank. Each panel is formed along either free end edge thereof with a cutout so that the blank is provided along either longitudinal edge thereof with a plurality of tabs each interposed between adjacent cutouts. The cutouts are dimensioned and configured such that the tabs have an identical size and configuration and are complementary to at least some of the cutouts.

  • Patent number: 6206279
    Abstract: A reclosable, stackable, standable package for food products such as baked goods easily converts from a parallelepiped form to a widened shape on top for easy access to the snack which is contained within an inner liner bag. The package stays in a widened open configuration throughout hand-to-mouth snacking even while resting on its front or back panel. The outer carton of the package has score lines on the front and the back panels of the carton extending from the lower corners of the front and the back panels to the center of the upper edge of the front and the back panels. Score lines also extend across the center of the top front and back flaps. The score lines in combination with the disconnected top flaps design not only allows the top of the package to form a wide oval shaped opening for easy access to the packaged goods, but also allows the package to stay opened while snacking.

  • Patent number: 5860588
    Abstract: A gable-top carton and a corresponding carton blank are set forth. The upstanding fin of the carton comprises a centrally disposed depressed region that facilitates stacking of the cartons on top of one another in a manner that results in a more even load distribution on the fins of the lower cartons than obtained when stacking conventional gable-top cartons. A further advantage is realized in the corresponding carton blanks in that the corresponding blanks may be disposed in a top-to-top manner along the width of a web of material whereby savings in material and production costs results.

  • Patent number: 5826786
    Abstract: A cup holder sleeve is formed in pre-assembled, flat-folded form by diecutting a flat, elongated band from blank stock material so as to have top and bottom arcuate edges concentric to and in parallel with each other, fold lines scored into the band at spaced apart positions tapering toward each other, and side edges at opposite ends of the band. The opposite ends are folded flat at the fold lines so that the side edges overlap each other and are glued together at their overlapping surfaces. The flat-folded form allows for compact storage. The pre-assembled sleeve can be readied for use simply by squeezing on the outside surfaces so as to bow out the flat-folded band into an annular tapered sleeve with opened top and bottom ends for inserting a cup therein. In a preferred embodiment, the sleeve is made of paperboard material and is printed with graphics and embossed with a pattern to provide an insulating layer as well as better gripping of the sides of the cup.
