The material of the paperboard substrate may be selected from any conventional paperboard, for example, ranging in weight upwardly from about 10 pt., preferably from about 16 pt. to about 28 pt. (0.028″/˜0.7 mm). An example of such a substrate is a 27 point (pt.) SBS board (solid bleached sulfate paperboard coated on one side, trade name PrintKote®) or CNK® board (Coated Natural Kraft®—an unbleached kraft paperboard having a clay coating on one side, trade name CarrierKote™) manufactured by WestRock® Company. The paperboard substrate may be a bleached or unbleached board. The board may be coated on at least one side, optionally the side opposite the lamination, with a conventional coating selected for compatibility with the printing method and board composition.
The blank 10 may include a coating or layer laminated to the paperboard layer. The coating or laminated layer may provide oil and grease resistance or tear resistance. It optionally includes an adhesive layer between the paperboard substrate and the laminated layer.
The tear resistant layer may be disposed over the uncoated side of the paperboard substrate and may be formed of polymeric material and secured to the substrate. The tear resistant layer imparts toughness to the laminate structure. Suitable tear resistant materials may include, but not be limited to, tear resistant laminated sheet material, e.g., NATRALOCK®, which may include a layer of an n-axially oriented film, e.g. MYLAR®, which is a bi-axially oriented polyester, oriented nylon, cross-laminated polyolefin or high density polyolefin. The orientation and cross-laminated structure of these materials contribute to the tear resistant characteristic. Also, tear resistance may be attributed to the chemical nature of the tear resistant material such as extruded metallocene-catalyzed polyethylene (mPE). Alternatively, the tear resistant layer may be a layer of linear low-density polyethylene (LLDPE). In embodiments where linear low-density polyethylene (LLDPE) or mPE is used, it is not necessary to incorporate an adhesive layer. Other suitable materials having a high level of tear resistance may also be used. The adhesive layer may be formed of polyolefin material such as a low-density polyethylene (LDPE). The adhesive layer may be placed between the substrate and the tear resistant layer to secure the tear resistant layer to the substrate.
The partition structure comprises an opening or gap allowing articles A to pass from one trough or chamber into an adjacent trough or chamber. A first article A in a first trough may be removed by a consumer creating a space or void in the first trough. A second article A in an adjacently disposed second trough may pass from the second trough through the opening in the partition structure into the void the first trough created upon removal of the first article A.
In the illustrated embodiment the first gate panel 16B retains or maintains the articles A in the first and second troughs when in a closed condition. In the closed condition the gate panel 16B is folded about fold line 15B to extend upwardly from the first base panel 14. When sufficient articles A have been removed from the second trough C2 the first gate panel 16B can be folded, as indicated by direction arrow D1, into an open condition. A portion of the first gate panel 16B may overly or overlap the second base panel 20. In the open condition articles A disposed in the first trough may pass into the second trough C2.
The second gate panel 24B similarly retains or maintains the articles A in the second and third troughs C2, C3 when in a closed condition and allows passage of articles A though a gap or opening in the partition structure when in an open condition.

In the second illustrated embodiment a first gate panel 116B is struck from the first divider panel 116 and a second gate panel 124B is struck from the fourth divider panel 124.
Opposed side edges of the first gate panel 116B are defined by a first pair of cut lines or severance lines 161A, 161B. The first pair of cut lines or severance lines 161A, 161B may be divergently arranged with respect to each other. The first pair of cut lines or severance lines 161A, 161B may be arranged to diverge towards the first base panel 114.
A first aperture A1 is struck from the second divider panel 118 and defines an end edge of the first gate panel 116B. The first aperture Al may be longer in a longitudinal direction than at least a portion of the first gate panel 116B. The free end edge of the first gate panel 116B is shorter than an adjacent portion of the first aperture A1.
Opposed side edges of the second gate panel 124B are defined by a second pair of cut lines or severance lines 163A, 163B. The second pair of cut lines or severance lines 163A, 163B may be divergently arranged with respect to each other. The second pair of cut lines or severance lines 163A, 163B may be arranged to diverge towards the third base panel 126.
A second aperture A2 is struck from the third divider panel 122 and defines an end edge of the second gate panel 124B. The second aperture A2 may be longer in a longitudinal direction than at least a portion of the second gate panel 124B. The free end edge of the second gate panel 124B is shorter than an adjacent portion of the second aperture A2.
The first gate panel 116B may be severably connected to the first divider panel 116. The second gate panel 124B may be severably connected to the fourth divider panel 124. In this way when the carrier is erected the first and second gate panels 116B, 124B are folded simultaneously with the respective one of the first and fourth divider panels 116, 124. The gate panel 116B, 124B can be separated from the respective one of the first and fourth divider panels 116, 124 when it is desired to open a portal in the partition structures created by the divider panels 116, 118, 122, 124.

It will be recognised that as used herein, directional references such as “top”, “bottom”, “base”, “front”, “back”, “end”, “side”, “inner”, “outer”, “upper” and “lower” do not necessarily limit the respective panels to such orientation, but may merely serve to distinguish these panels from one another.
As used herein, the terms “hinged connection” and “fold line” refer to all manner of lines that define hinge features of the blank, facilitate folding portions of the blank with respect to one another, or otherwise indicate optimal panel folding locations for the blank. Any reference to “hinged connection” should not be construed as necessarily referring to a single fold line only; indeed a hinged connection can be formed from two or more fold lines wherein each of the two or more fold lines may be either straight/linear or curved/curvilinear in shape. When linear fold lines form a hinged connection, they may be disposed parallel with each other or be slightly angled with respect to each other. When curvilinear fold lines form a hinged connection, they may intersect each other to define a shaped panel within the area surrounded by the curvilinear fold lines. A typical example of such a hinged connection may comprise a pair of arched or arcuate fold lines intersecting at two points such that they define an elliptical panel therebetween. A hinged connection may be formed from one or more linear fold lines and one or more curvilinear fold lines. A typical example of such a hinged connection may comprise a combination of a linear fold line and an arched or arcuate fold line which intersect at two points such that they define a half moon-shaped panel therebetween.
As used herein, the term “fold line” may refer to one of the following: a scored line, an embossed line, a debossed line, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, an interrupted cutline, a line of aligned slits, a line of scores and any combination of the aforesaid options.
It should be understood that hinged connections and fold lines can each include elements that are formed in the substrate of the blank including perforations, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cutline, an interrupted cutline, slits, scores, embossed lines, debossed lines, any combination thereof, and the like. The elements can be dimensioned and arranged to provide the desired functionality. For example, a line of perforations can be dimensioned or designed with degrees of weakness to define a fold line and/or a severance line. The line of perforations can be designed to facilitate folding and resist breaking, to facilitate folding and facilitate breaking with more effort, or to facilitate breaking with little effort.
The phrase “in registry with” as used herein refers to the alignment of two or more elements in an erected carton, such as an aperture formed in a first of two overlapping panels and a second aperture formed in a second of two overlapping panels. Those elements in registry with each other may be aligned with each other in the direction of the thickness of the overlapping panels. For example, when an aperture in a first panel is “in registry with” a second aperture in a second panel that is placed in an overlapping arrangement with the first panel, an edge of the aperture may extend along at least a portion of an edge of the second aperture and may be aligned, in the direction of the thickness of the first and second panels, with the second aperture.
