The arrangement shown is configured to accommodate four articles B in <NUM> x <NUM> matrix or array.

<FIG> illustrates a blank <NUM> according to a third embodiment, the blank <NUM> comprises a main panel <NUM> for forming an engaging panel of a carrier (not shown). In the third illustrated embodiment, like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix "<NUM>" to indicate that these features belong to the third embodiment.

The alternative embodiment shares many common features with the embodiment of <FIG>, therefore only the differences from the embodiment illustrated in <FIG> will be described in any greater detail.

The main panel <NUM> is adapted to accommodate twelve articles B arranged in a <NUM> x <NUM> matrix or array, the main panel <NUM> comprises a first marginal column of article retention structures RT1, RT4 substantially similar in construction to those in <FIG> and a second marginal column of article retention structures RT2, RT3 substantially similar in construction to those in <FIG>. The main panel <NUM> comprises an intermediate column of article retention structures RT5, RT6. The intermediate column comprises a fifth article retention structure RT5 and a plurality of sixth article retention structures RT6. The fifth article retention structure RT5 is substantially similar in construction to the second article retention structure RT2 of <FIG> albeit the second tooth <NUM> has been replaced with an additional third tooth <NUM>, the additional third tooth <NUM> is arranged back-to-back with a fifth tooth <NUM> of a second article retention structure RT2 in the second marginal column of article retention structures RT2, RT3. Similarly, the sixth article retention structure RT6 is substantially similar in construction to the third article retention structure RT3 of <FIG> albeit the second tooth <NUM> has been replaced with an additional third tooth <NUM>, the additional third tooth <NUM> is arranged back-to-back with a fifth tooth <NUM> of a third article retention structure RT3 in the second marginal column of article retention structures RT2, RT3. The sixth article retention structures RT6 comprise four engaging tabs <NUM>, <NUM> which are arranged back-to-back with an engaging tooth <NUM>, <NUM> in an adjacently disposed article retention structure RT1, RT2, RT3, RT4, RT5, RT6. The aforementioned four engaging tabs <NUM>, <NUM> are arranged in diametrically opposed pairs, a first pair being oriented orthogonally with respect to the second pair.

The blanks <NUM>; <NUM> include at least a paperboard substrate. The material of the paperboard substrate may be selected from any conventional paperboard, for example, ranging in weight upwardly from about 10pt. , preferably from about 16pt. to about 28pt. (<NUM>"/~<NUM>). An example of such a substrate is a <NUM> point (pt. ) SBS board (solid bleached sulphate 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 CarrierKoteTM) 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 blanks <NUM>; <NUM> may include a tear resistant layer laminated to the paperboard layer. It optionally includes an adhesive layer between the paperboard substrate and the tear resistant 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-catalysed 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.

It will be recognized 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.
