  • the main panels 122 , 124 e.g., biconcave panels
  • the minor panels 126 , 128 e.g., biconvex panels
  • these concave and convex edges are respectively foldably connected to one another by the arcuate lines of disruption 132 , 134 , 136 , 138 .
  • other possibilities are contemplated.
  • the susceptor film 148 may be joined (e.g., laminated) to a support layer 152 , for example, paper, using an adhesive or otherwise (not shown), to impart dimensional stability to the susceptor film 148 (and resulting package 154 ) and/or to protect the layer of microwave energy interactive material 144 from being damaged.
  • the blank 100 may be folded along lines of disruption 140 , 142 .
  • Panels 126 a , 130 may be overlapped with one another (e.g., so that peripheral edge 116 is substantially aligned with line of disruption 140 ), and the peripheral margins of the first component 102 adjacent to peripheral edges 106 , 108 may be overlapped with one another.
  • the respective overlapping portions of the sheets 102 , 104 may be joined to one another in any suitable manner, for example, using an adhesive, to form a substantially flat, tubular structure including an interior space 156 (shown in FIGS.
  • the package 154 may be transitioned from this substantially flattened configuration to an open, expanded (e.g., erected) configuration by urging lines of disruption 140 , 142 towards one another and/or moving panels 122 , 124 away from one another, and folding the package 154 along lines of disruption 132 , 134 , 136 , 138 , 140 , 142 .
  • panels 126 , 128 , 130 are moved inwardly so that the reinforcing sheath or sleeve 104 formed from the second sheet 104 defines a contoured package shape with incurved sides.
  • the intermediate lines of disruption 140 , 142 are configured for allowing the minor panels 126 , 128 to be folded in a manner so that, for each minor panel, its opposite convex edges may be moved both toward and away from one another, for at least partially erecting or unerecting the incurved sides.
  • the incurved sides they comprise each of the minor panels 126 , 128 (e.g., biconvex panels) as a whole being in a substantially concave configuration with respect to the interior of the carton (e.g., sleeve) of the package 154 , wherein the minor panels are retained in their substantially concave configurations at least partially in response to interplay between forces in the carton of the package 154 .
  • the package 154 being held by hand or placed in a cup holder, or the like, may also help to at least partially retain the minor panels 126 , 128 in their substantially concave configurations.
  • the carton of the package 154 has opposite open ends that do not include, and are not closed by, end flaps of the carton, wherein the above-mentioned substantially concave configurations of the panels 126 , 128 and/or the interplay between forces in the carton of the package 154 maintain the carton in its erected configuration.
  • the package may be configured to have any other shape, for example, a somewhat tubular or cylindrical shape, a somewhat rectangular shape, or any other regular or irregular shape.
  • the carton or sleeve of the package may further include one or more end flaps for at least partially closing one or both of the ends of the carton or sleeve.
  • the package 154 may be brought into an upright configuration with the closed end 160 of the package facing downwardly, as shown schematically in FIGS. 1F and 1G .
  • panels 122 , 124 , 126 , 128 , 130 (some of which are hidden from view in FIGS. 1F and 1G ) provide structural stability for the flexible pouch 102 and assist with maintaining the pouch in an open configuration so the food or other package contents can be readily accessed, even when the food is being consumed on the go.
  • the incurved portions of the reinforcing sleeve 104 define a curved outer surface of the package that facilitates grasping of the package.
  • the carton portion of the package 154 is in the form of a sleeve having opposite top and bottom ends; the bag portion of the package is positioned in the interior of the sleeve; the top end of the bag extends upwardly, outwardly through an opening of the top end of the sleeve; the sealed closed bottom end of the bag extends downwardly, outwardly through an opening of the bottom end of the sleeve; and the top and bottom ends of the bag are wider than the sleeve.
  • peripheral edge 120 may serve as a bottom edge for supporting the package when placed on a surface.
  • a food item may be inserted into the interior space 156 at any suitable time and the open end of the package may be sealed. Alternatively, one end may remain unsealed and the user may be instructed to insert the food into the interior space prior to use.
  • the package 154 may be pre-expanded to fit the package contents or to provide a void volume within the interior space 156 to accommodate the expansion of the food during heating. It is also contemplated that the package 154 may expand further during heating, for example, in response to the expansion of the food (e.g., popcorn).
  • the food e.g., popcorn
  • the microwave energy interactive material 144 may be configured as a susceptor, so that the package 154 may be used to at least one of heat, brown, and crisp the food, for example, in a microwave oven.
  • the package may include microwave energy interactive material that alters the effect of microwave energy on the food.
  • the microwave energy interactive material 144 When the microwave energy interactive material 144 is in the form of a susceptor, it may be configured as a thin layer of microwave energy interactive material generally less than about 100 angstroms in thickness, for example, from about 60 to about 100 angstroms in thickness, and having an optical density of 0.15 to about 0.35, for example, about 0.17 to about 0.28.
  • microwave energy reflecting (or reflective) elements may be used as shielding elements where the food item is prone to scorching or drying out during heating.
  • smaller microwave energy reflecting elements may be used to diffuse or lessen the intensity of microwave energy.
  • One example of a material utilizing such microwave energy reflecting elements is commercially available from Graphic Packaging International, Inc. (Marietta, Ga.) under the trade name MicroRite® packaging material.
  • a plurality of microwave energy reflecting elements may be arranged to form a microwave energy distributing element to direct microwave energy to specific areas of the food item. If desired, the loops may be of a length that causes microwave energy to resonate, thereby enhancing the distribution effect. Examples of microwave energy distributing elements are described in U.S. Pat. Nos. 6,204,492, 6,433,322, 6,552,315, and 6,677,563.
