BACKGROUNDDispensing 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 that are dispensable through the top panel or another panel when the carton is opened. Typically, the 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. Conventional dispensing cartons are also typically suited to store only one type of article, and therefore multiple vessels are required to carry various items, such as containers and dry snacks.
SUMMARYIn the present disclosure, cartons, carton blanks, and methods of manufacturing and using cartons are described. In one embodiment, among others, a carton, which is formed from a carton blank, comprises a lower storage compartment having at least one panel. The carton also includes a lid connected to a first panel of the lower storage compartment. The lid is configured to be pivotable with respect to the lower storage compartment. Also, the carton includes an upper storage compartment formed within the lid. The lid comprises a lower lid panel that separates the lower storage compartment from the upper storage compartment.

Other aspects, features, and details of the present disclosure can be more completely understood by reference to the following detailed description of a preferred embodiment, taken in conjunction with the drawings and from the appended claims.
According to common practice, the various features of the drawings discussed below are not necessarily drawn to scale. Dimensions of various features and elements in the drawings may be expanded or reduced to more clearly illustrate the embodiments of the present disclosure.
The first embodiment of the present disclosure generally relates to a carton suitable for storing and dispensing articles such as, for example, beverage containers. The carton is also suitable for storing and dispensing articles of a second type, such as dry snacks, in a separate compartment. In accordance with the first embodiment, the carton includes a bottom receptacle suitable for accommodating, for example, liquids, ice, or other coolants in the carton bottom. In one exemplary embodiment, ice can be added to the opened carton to cool articles held within the carton. As the ice melts, all or a part of the resultant runoff water may be at least temporarily held within the bottom receptacle.
Articles accommodated in a bottom portion of the carton can include containers such as, for example, petaloid bottle containers, beverage cans, glass or plastic bottles, or other containers such as, for example, those used in packaging foodstuffs. For the purposes of illustration and not for the purpose of limiting the scope of the present disclosure, the following detailed description describes beverage containers as disposed within the carton embodiments. In this specification, the terms “lower,” “upper,” “bottom,” “front” and “back” indicate orientations determined in relation to fully erected, upright cartons.
The blank 8 comprises a lower lid panel 10 adjacent to a front panel 40, a bottom panel 50 foldably connected to the front panel 40 at a transverse fold line 51, a back panel 60 foldably connected to the bottom panel 50 at a transverse fold line 61, an upper lid panel 70 foldably connected to the back panel 60 at a transverse fold line 76, and a front adhesive panel 90.
First gussets 45 are disposed at either end of the front panel 40. The first gussets 45 comprise a pair of gusset panels 42, 46 foldably connected to one another at an oblique fold line 44. Each gusset panel 42 is foldably connected to the front panel 40 at a longitudinal fold line 106, and each gusset panel 46 is foldably connected to a bottom end panel 52 at the transverse fold line 51. An adhesive flap 54 is foldably connected to each bottom end panel 52 at a longitudinal fold line 56.
Second gussets 65 are disposed at either end of the back panel 60. The second gussets 65 comprise a pair of gusset panels 62, 66 foldably connected at an oblique fold line 64. Each gusset panel 62 is foldably connected to the back panel 60 at the longitudinal fold line 106, and each gusset panel 66 is foldably connected to a bottom end panel 52 at the transverse fold line 61.
The periphery of the lower lid panel 10 is defined at one end of the blank 8 by a separation pattern, which includes, for example, spaced longitudinal cuts 20, oblique cuts 22, and a transverse cut 24 connecting the oblique cuts 22. More generally, as in one example, the periphery of the lower lid panel 10 is defined by one or more tear lines, slits, or any combination thereof. The lower lid panel 10 can be retained in place in the blank 8 by nicks around the periphery of the lower lid panel 10. The nicks, for example, are “bridging” pieces of the blank 8 located between slits in the blank 8. An adhesive panel 12 is in part defined at one end of the panel 10 by a transverse fold line 14, and an adhesive panel 16 is in part defined at the other end of the lower lid panel 10 by a transverse fold line 18. The middle section of the lower lid panel 10 is intermediate between adhesive panels 12 and 16. Longitudinal panels 28 extend along each side of the lower lid panel 10 and are foldably connected to the front panel 40 at transverse fold lines 41.
The periphery of the upper lid panel 70 is defined by a transverse fold line 74, spaced longitudinal tear lines 80, oblique tear lines 92, and a tear line 94 connecting the oblique tear lines 92. The tear lines 80, 92, and 94 allow the upper lid panel 70 to remain in place with respect to the adjoining panels. However, the tear lines 80, 92, and 94 can be torn by a user without special cutting tools to separate the upper lid panel from longitudinal panels 78 and the front adhesive panel 90. After the tear lines are torn, the upper lid panel 70 can be pivoted as explained in more detail below. A pivot panel 72 is defined at one end of the upper lid panel 70 in part by a transverse fold line 76. A spacer panel 84 is defined in the other end of the upper lid panel 70 in part by transverse fold lines 83, 86. An adhesive panel 88 is foldably connected to the spacer panel 84 at the transverse fold line 86. The longitudinal panels 78 extend along each side of the upper lid panel 70 and are foldably connected to the back panel 60 at transverse fold lines 63. The front adhesive panel 90 extends from the end of the blank 8 and is foldably connected to the longitudinal panels 78 at transverse fold lines 91.
Inner handle panels 30 are foldably connected to the longitudinal panels 28 at the fold lines 106. Apertures 34 can be formed along the fold lines 106 to facilitate folding of the handle panels 30. Cut-out 32, which in some embodiments form racetrack-shaped handles, are formed in the handle panels 30. Outer handle panels 100 are foldably connected to the longitudinal panels 78 at the fold lines 106. The outer handle panels 100 include handles 102 that are arranged to align with the cut-outs 32, e.g., handles, in the erected carton 190.
According to one exemplary aspect of the present disclosure, the gussets 45, 65, the front panel 40, the back panel 60, the bottom end panels 52, and bottom panel 50 form a wholly or partially liquid-tight bottom receptacle 175 (illustrated in
An exemplary method of erection of the blank 8 into the carton 190 will now be discussed with reference to
The exterior sides of the longitudinal panels 28 are typically adhered to the interior or undersides of the longitudinal panels 78, and the exterior sides of the handle panels 30 are typically adhered to the interior sides of the handle panels 100 so that the handles 32, 102 align. The interior side or underside of the front adhesive panel 90 is adhered to the exterior side of the front panel 40. The ends of the partially erected carton may now be closed by the first and second gussets 45, 65 and the bottom end panels 52. The discussion below describes closing of one end of the partially erected blank. The opposite end may be closed in a similar manner.

According to another aspect of the present disclosure, the height HR may be, for example, defined as a function of a height of the carton 190. For example, referring to
According to one aspect of the present disclosure, the upper storage compartment 160 in the lid 150 may be used to store items separate from items accommodated in the lower storage compartment 170. For example, the upper storage compartment 160 may be a “dry” compartment used to accommodate items such as packaged foods. The lower storage compartment 170 can be a “wet” compartment used to accommodate beverage containers C, and, if desired, ice or other coolant substances.
If desired, additional articles may be placed in the carton 190 after opening. For example, if the containers C are beverage containers, ice may be placed over the containers C and held within the lower storage compartment 170 to cool the containers C. As the ice melts, the bottom receptacle 175 of the carton 190 serves to retain all or a portion of the water runoff as the ice melts. The receptacle 175 may also serve, for example, to house fine particulate matter that might otherwise escape through a glued seam. If one or more containers C is damaged during shipping or storage of the carton 190, the bottom receptacle 175 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 190 remains in the bottom receptacle 175 for a selected amount of time. The carton 190 can therefore be constructed so that liquid retained in the bottom receptacle 175 initially remains in the carton 190 at least until it reached the height HR.
Cartons constructed according to the principles of the present disclosure may be formed from materials such as paperboard. 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. In this specification, 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.
In order to reduce the permeability of cartons to liquid, blanks according to the present disclosure may be coated with, for example, a moisture barrier layer, on either or both sides of a blank. Blanks can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections. For example, the interior surfaces of the blank 8 may include a water-resistant or water-tight film such as, for example, polyethylene, polyester, or polypropylene films. Coatings of the same materials may also be applied to the blank 8. Accordingly, the sheet from which the blank 8 is cut may have multiple plys.
In the above embodiments, the carton 190 is illustrated as accommodating eight containers C in a 2×4 configuration. Other arrangements of containers, packages, articles, and other items, however, can be accommodated within a carton according to the principles of the present disclosure. For example, a carton constructed according to the principles of the present disclosure would also work satisfactorily if the carton were sized and shaped to hold articles in other configurations, such as 3×4, 4×3, 3×6, 2×4, 2×5, etc. The dimensions of the blank 8 may also be altered, for example, to accommodate various container forms. For example, 16-ounce petaloid bottles may be accommodated within a carton constructed according to the principles of the present disclosure.
In the exemplary embodiments discussed above, the exemplary blank 8 may be formed from, for example, clay coated newsprint (CCN), solid unbleached sulfate board (SUS), and/or other materials. In general, the blank 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 blank 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.
The blank can be coated with, for example, a clay coating. The clay coating may then be printed over with product advertising and/or other information or images. The blank may then be coated with a varnish to protect information printed on the blank.
In the present specification, a “panel” need not be flat or otherwise planar. A “panel” can, for example, comprise a plurality of interconnected generally flat or planar sections.
The above embodiments may be described as having one or more panels adhered together by glue. The term “glue” is intended to encompass all manner of adhesives commonly used to secure paperboard carton panels in place.
The term “line” as used herein includes not only straight lines, but also other types of lines such as curved, curvilinear or angularly displaced lines.
In accordance with the exemplary embodiments, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present disclosure, fold lines include: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed or depressed portion in the material along the desired line of weakness; a cut that extends partially into a material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; and various combinations of these features. In situations where cutting is used to create a fold line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the fold line to be a tear line.
In the illustrated embodiments, selected fold lines may be shown as including spaced cuts to facilitate folding along the lines. If the cuts are below or adjacent to the bottom receptacle 175 portion of the carton, less than 100% cuts, e.g., cuts that do not extend all the way through the blank, may be used to prevent leakage along the fold lines. Alternatively, cuts or scores may be omitted within or near the bottom receptacle 175.
The term “tear line” as used herein can be any fold, cut, puncture, slice, slit, perforation, etc., or any combinations thereof, which allows the blank 8 to be folded along an intended line. When the tear lines contains slits, for example, the slits are typically aligned nearly end-to-end including bridges between them, wherein the bridges can be ripped. The tear lines can also be formed using a kiss cut that cuts through one surface of the blank 8, but does not extend all the way through it.
The foregoing description of the present disclosure illustrates and describes selected embodiments. However, it is to be understood that the present disclosure is not limited by the exemplary embodiments, but can include other modifications and changes within the spirit and scope of the descriptions expressed herein. Such modifications known to one of ordinary skill in the art are intended to be included within the present disclosure and limited only by the following claims.
