[0137] The fold line 13 that hinges the first end panel 14 to the main panel 12 is non-linear and may be curvilinear or arcuate. The fold line 13 that hinges the first end panel 14 to the main panel 12 extends substantially between a pair of adjacently disposed first article retaining structures RT1. The fold line 13 defines a convex hinged portion when viewed from an exterior perspective.

[0138] The fold line 15 that hinges the second end panel 16 to the main panel 12 is non-linear and may be curvilinear or arcuate. The fold line 15 that hinges the second end panel 16 to the main panel 12 extends substantially between a pair of adjacently disposed first article retaining structures RT1. The fold line 15 defines a convex hinged portion when viewed from an exterior perspective.

[0139] The fold line 17 that hinges the first side panel 18 to the main panel 12 may be non-linear and curvilinear or arcuate. The fold line 17 that hinges the first side panel 18 to the main panel 12 comprises a plurality of curvilinear portions that extend substantially between a pair of adjacently disposed article retention structures RT1, RT2. The fold line 17 defines a plurality of convexly hinged portions when viewed from an exterior perspective.

[0140] The fold lines 19 that hinge the second side panel 20 to the main panel 12 may be non-linear and curvilinear or arcuate.

The fold lines 19 define a plurality of convexly hinged portions when viewed from an exterior perspective.

[0141] Each curved hinged portion extends substantially between a pair of tabs 42,44.

[0142] Each curved fold line 13, 15, 17, 19 curves toward and terminates at or adjacent a curvilinear hinge connection between a group of teeth 40a, 40b, 40c; 50a, 50b, 50c.

[0143] Each curved fold line 13,15,17,19 and / or curvilinear hinge connection between the groups of teeth 40a,40b,40c; 50a,50b,50c terminates at or adjacent an end of the cut that defines the tab 42,44.

[0144] In the embodiment shown in Fig. 1, the fold lines 13, 15, 17, 19 are defined by a plurality of spaced apart cuts. The curvilinear hinge connection between the group of teeth 40a, 40b, 40c; 50a, 50b, 50c and the main panel 12 is defined by a plurality of spaced apart peripheral cuts 43, 45, 53, 55.

[0146] This can provide the benefit of directing additional forces or stresses toward the sidewalls of article B so as to increase the structural integrity or rigidity of carrier 90, which can be particularly advantageous against impact forces directed toward the edges or sides of carrier 90.

[0147] The curved fold lines 13, 15, 17, 19 can create tension or bias in the side or end walls 14, 16, 18, 20. This can increase the resistance of the side or end walls 14, 16, 18, 20 to impacts.

[0148] The curved fold lines 13, 15, 17, 19 can create tension or bias in the side or end walls 14, 16, 18, 20, which can have the effect of creating bi-stability, an over-center or toggle mechanism that creates two stable states or positions, a folded stable position and an unfolded stable position. This can, either in addition to or instead of the tabs 42, 44, facilitate retention of the side or end walls 14, 16, 18, 20 to the main panel 12 in the folded position. In this manner, the requirement for adhesives or other such fastening means can be eliminated.

[0149] The fold lines 13,15,17,19 are non-linear such that at least one end portion thereof curves around one of the item retaining structures RT1,RT2 toward an adjacent annular fold line, the annular fold line being defined by a plurality of peripheral cuts 43,45,53,55.

Corner regions 12a, 12b, 12c, 12d slope upwardly as they extend outwardly due to the converging nature of fold line pairs 13a / 17a; 13b / 19a; 15a / 17b; 15b / 19b. This provides additional strength or rigidity to carrier 90 and can be beneficial in reducing the possibility of deformation when carrier 90 is wrapped with a sheet or film of material, such as, but not limited to, heat or shrink wrap.

[0175] In the assembled carrier 90, each of the curved fold lines 13, 15, 17, 19 joins or connects with a curvilinear hinge connection between an adjacent group of teeth 40a, 40b, 40c; 50a, 50b, 50c and the main panel 12. The curved fold lines 13, 15, 17, 19 and the curvilinear hinge connections may define or form a meeting fold or crease in the substrate forming the carrier 90. In other embodiments, each of the curved fold lines 13, 15, 17, 19 may be joined or connected to an adjacent curvilinear hinge connection by a third fold or crease. The curved fold lines 13, 15, 17, 19 and the curvilinear hinge connections meet or connect at a location disposed proximate to the article B.

[0176] In some embodiments, the curved fold lines 13, 15, 17, 19 have the effect of causing the side and / or end walls 14, 16, 18, 20 to bend outwardly in the areas between pairs of adjacent articles B so as to be convex when viewed from an external vantage point.

[0177] In some embodiments, the curved fold lines 13, 15, 17, 19 have the effect of directing the main panel 12 to bend downwardly in the areas between pairs of adjacent articles B so as to be concave when viewed from an exterior vantage point above the main panel 12. In such embodiments, the side and / or end walls 14, 16, 18, 20 may be substantially planar.

[0273] The blanks 10; 110; 210; 310; 410; 510; 610; 710; 810 include at least a paperboard substrate. The paperboard substrate material may be selected from any conventional paperboard, for example, ranging in weight from about 10 pt. and up, preferably from about 16 pt. to about 28 pt. (0.028 inches / about 0.7 mm). Examples of such substrates are 27 point (pt.) SBS cardboard (PrintKote®, a solid bleached sulfate board coated on one side) or CNK® cardboard (Coated Natural Kraft® - CarrierKote™, an unbleached kraft board with a clay coat on one side) manufactured by the WestRock® Company. The paperboard substrate may be bleached or unbleached cardboard. The cardboard may be coated on at least one side, and optionally the side opposite the lamination, with a conventional coating selected for compatibility with the printing method and cardboard composition.

[0274] The blank 10;110;210;310;510;610;710;810 may include a tear-resistant layer laminated to the paperboard layer.

The tear-resistant layer may be disposed over the uncoated side of the paperboard substrate and may be formed of a polymeric material and secured to the substrate. The tear-resistant layer provides toughness to the laminate structure. Suitable tear-resistant materials may include, but are not limited to, tear-resistant laminate sheet materials such as NATRALOCK®, which may include layers of n-axis oriented films such as MYLAR®, which are biaxially oriented polyester, oriented nylon, cross-laminated polyolefin, or high density polyolefin. The orientation and cross-lamination structure of these materials contribute to the tear resistance properties, which may also be attributed to the chemistry of the tear resistant materials, such as extruded metallocene-catalyzed polyethylene (mPE).

[0275] 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 degree of tear resistance may be used.

[0276] The adhesive layer may be formed from a polyolefin material, such as low density polyethylene (LDPE). The adhesive layer may be disposed between the substrate and the tear resistant layer to secure the tear resistant layer to the substrate.

[0305] It will be understood that various modifications can be made within the scope of the invention. For example, the size and shape of the panels and openings can be adjusted to accommodate items of different sizes or shapes. Shoulder panels may be omitted. The invention is not limited to top-engaging types of cartons, and the invention may be used with other carton styles, such as, but not limited to, open top crates, lidded or closed top crates.

[0306] It will be appreciated that, as used herein, references to directions such as "top," "bottom," "bottom," "front," "back," "end," "side," "inward," "outward," "above," and "below" do not necessarily limit each panel to such orientation, but may merely serve to distinguish these panels from one another.

[0307] As used herein, the terms "hinge connection" and "fold line" refer to any manner of line that defines a hinge feature of a blank, facilitates folding portions of the blank relative to one another, or otherwise indicates the optimal location for folding a panel on the blank. References to "hinge connection" should not necessarily be construed as referring only to a single fold line, and in fact a hinge connection may be formed from two or more fold lines, each of which may be either straight / linear or curved / curved in shape. When linear fold lines form a hinge connection, they may be disposed parallel to one another or may be slightly angled relative to one another. When curved fold lines form a hinge connection, they may intersect with one another to define a molded panel within the area enclosed by the curved fold line. A typical example of such a hinge connection may comprise a pair of arched or arcuate fold lines that intersect at two points to define an elliptical panel therebetween. The hinge connection may be formed from one or more linear fold lines and one or more curvilinear fold lines. A typical example of such a hinge connection may comprise a combination of a linear fold line and an arched or bowed fold line that intersect at two points to define a half-moon shaped panel therebetween.

[0308] As used herein, the term "fold line" may refer to one of the following: a perforation line, an embossed line, a debossed line, a perforation line, a short slit line, a half-cut line, a single half-cut, an interrupted cut, a line of aligned slits, a perforation line, and any combination of the foregoing options.

[0309] It should be understood that each of the hinge connections and fold lines may each include elements formed in the blank substrate, including perforations, perforation lines, short slit lines, half-cut lines, single half-cuts, cuts, interrupted cuts, slits, perforations, embossed lines, debossed lines, any combination thereof, and the like. The elements may be sized and arranged to provide the desired functionality. For example, perforation lines may be sized or designed with a degree of weakness to define fold and / or cut lines. Perforation lines may be designed to facilitate folding while resisting tearing, to facilitate folding while facilitating tearing with greater effort, or to facilitate tearing with less effort.

[0310] The phrase "in registration with" as used herein refers to the alignment of two or more elements in an erected carton, such as an opening formed in a first of two overlapping panels and a second opening formed in a second of the two overlapping panels. The elements that are in registration with each other may be aligned with each other in the thickness direction of the overlapping panels. For example, when an opening in a first panel is "in registration with" a second opening in a second panel that is placed in an overlapping arrangement with the first panel, an edge of the opening may extend along at least a portion of an edge of the second opening and may be aligned with the second opening in the thickness direction of the first and second panels.
