Definitions

  • Dispensing cartons are known.
  • Conventional dispensing cartons may have a top panel with a dispensing feature formed therein.
  • Such cartons may be used to contain articles such as beverage containers, for example, that are dispensable through the top panel or through another panel when the carton is opened.
  • conventional cartons must be refrigerated in order to keep the enclosed containers cool. When the cartons are no longer refrigerated, such as when the carton is removed from the refrigerator to dispense the containers, the containers may become undesirably warm. The containers must then be refrigerated again or otherwise cooled. Further, the dispensing features included in conventional cartons may render the cartons incapable of being securely reclosed once opened.
  • Articles retained within the carton may therefore inadvertently fall out of the carton once the carton has been opened.
  • Conventional cartons are typically formed from a single ply of paperboard or similar material. Carrying handles may be formed in one or more panels of the carton and used to carry the carton. Because cartons are often used to carry relatively heavy articles, such as beverage containers, the strength of the handles or other sections of the cartons must be increased in order to accommodate the carton load.
  • a conventional method for increasing the load-bearing capacity of a paperboard carton is to produce the carton from a blank of a different, stronger paperboard material, or to produce the blank from the same carton material but having greater thickness or caliper.
  • Such conventional methods typically increase the costs associated with manufacturing the carton, with the material costs of manufacture generally increasing according to the cost of increasing the strength and/or thickness of the entire blank. Some sections of the blank, however, may not be load- bearing, and the additional costs associated with increasing the strength of non-load bearing sections of the blank are wasted.
  • a carton is formed from at least a major blank and a minor blank joined to the major blank.
  • the carton comprises a first side panel, a bottom panel, a second side panel, a first end panel, a second end panel, and a plurality of gussets.
  • One gusset is located at each corner of the bottom panel and is disposed between and foldably connected to an adjacent side panel and end panel so as to seal or close off the corners of the carton.
  • the minor blank may be configured to render the carton multi-ply at selected sections.
  • the first side panel, the second side panel and the plurality of gussets are formed from at least the major blank, and the bottom panel and the first and second end panels are formed from overlapping sections of the major and minor blanks.
  • the minor blank reinforces the major blank so as to increase the strength and load-bearing capacity of the multi-ply carton.
  • the minor blank can be configured to reinforce the major blank at any number of desired locations. Selected reinforcement of specific areas of the major blank can produce a high strength carton having a high load-bearing capacity while using relatively small amounts of board.
  • a top closure can be opened and ice, cold water, additional containers, and/or other articles can be placed in the carton through the opened top end.
  • the interior volume of the carton can be used to retain liquids, such as water resulting from melting ice, condensation, other liquids, and articles such as, for example, refuse, particulate matter, etc.
  • the carton can include side top panels foldably connected to the side panels.
  • the carton can be placed in an expanded configuration in which the side top panels extend generally upwardly to in part define an increased interior volume of the carton.
  • Closure panels can be foldably connected to the side top panels. The closure panels and side top panels close a top of the carton prior to placing the carton in the expanded configuration. The closure panels alone can be used to close the top of the carton when the carton is in its expanded configuration.
  • the carton can include handle panels that in part define the interior carton volume when the carton is in its expanded configuration.
  • the handle panels can be used to carry the carton before opening of the carton, when the carton is in the expanded configuration with the top of the carton open, and when the carton is in the expanded configuration with the top closed.
  • a bottom receptacle of the carton can be constructed to have a height that extends above the bottom panel of the carton, below which there are no seams sealed by glue or other adhesives. The bottom receptacle may therefore be liquid-tight.

  • the carton provides a bottom receptacle suitable for accommodating, for example, liquids, ice, or other coolants in the carton bottom.
  • ice can be added to the opened top of the carton to cool beverage containers held within the carton. As the ice melts, all or a part of the resultant runoff water may be held within the bottom receptacle.
  • the carton can also include a reclosure feature in which closure panels can be engaged with one another to close the opened top of the carton.
  • a reinforcing minor blank can extend across the bottom of the carton and upwardly into handles of the carton to increase the load-bearing capacity of the carton.
  • Articles accommodated within the present carton embodiments can include containers such as, for example, petaloid bottle beverage containers, metallic beverage cans, glass or plastic bottles, or other containers such as, for example, those used in packaging foodstuffs and other products.
  • containers such as, for example, petaloid bottle beverage containers, metallic beverage cans, glass or plastic bottles, or other containers such as, for example, those used in packaging foodstuffs and other products.

  • the minor blank 6 is adhered to the interior side of the major blank 5, although it may be adhered to the exterior side.
  • the multi-ply blank 8 is "multi-ply" in that the joined minor and major blank plies 6 and 5 comprising the multi-ply blank 8 include substantial overlapping portions. Also, a majority of the overlapping surfaces of the minor and major blank plies 6, 5 may be adhered adjacent to one another. For example, the blanks 5 and 6 have different perimeters or "footprints" and need not overlap at all points, but at least substantially all of the surface of the minor blank 6 may be adjacent and/or adhered to the interior side of the major blank 5.
  • the blank 8 may be symmetric or nearly symmetric about a transverse centerline C ⁇ and a longitudinal centerline C L .
  • the major blank 5 and the minor blank 6 may also be symmetric about the transverse centerline C ⁇ and the longitudinal centerline C L .

If one or more containers C is damaged during shipping or storage of the carton 160, the bottom receptacle 165 can serve to retain all or a portion of the contents of the broken container.
  • the blank 8 can, for example, be constructed of water resistant material to any degree desired so that liquid in the bottom of the carton 160 remains in the bottom receptacle 165 for a selected amount of time.

Therefore, if exposed to water or other liquids for extended periods of time, the carton may allow for the passage of liquid through the wetted carton surfaces due to partial permeability of the carton material.
  • the term "liquid-tight" is generally used to define a section of a carton that is formed from a continuous section of material or of a section without any glued seams through which liquid or fine particulate matter might leak, and the term “liquid- tight” therefore encompasses cartons that may become partially water permeable over time due to prolonged exposure to water or other liquids.

  • a carton constructed according to the principles of the present invention would also work satisfactorily if the carton were sized and shaped to hold articles in other configurations, such as 3 x 4 x 1, 4 x 3 x 1 , 3 x 6 x 1 , 2 x 4 x 1 , 2 x 5 x 1, 2 x 6 x 1 , 4 x 6 x 1 , etc., and multi-tier variations of the aforementioned configurations.

  • the major and minor blanks may be formed from, for example, clay coated newsprint (CCN), solid unbleached sulfate board (SUS), and other materials.
  • the blanks may be constructed from paperboard having a caliper of at least about 14, for example, so that it is heavier and more rigid than ordinary paper.
  • the blanks can also be constructed of other materials, such as cardboard, or any other material having properties suitable for enabling the carton to function at least generally as described above.
