Referring to Figure 1 , there is shown a plan view of a blank 10 capable of forming a carton or carrier 90, as shown in Figures 2 to 4, for carrying a group of primary products such as, but not limited to, bottles, hereinafter referred to as articles B. The blank 10 forms a secondary package or handle structure for packaging at least one primary product container or package.

In the embodiments detailed herein, the terms “carton” and “carrier” refer, for the non-limiting purpose of illustrating the various features of the invention, to a container 90 for engaging and carrying articles, such as primary product containers. It is contemplated that the teachings of the invention can be applied to various product containers, which may or may not be tapered and/or cylindrical. Other exemplary containers include bottles (for example metallic, glass or plastics bottles), cans (for example aluminium cans), tins, pouches, packets and the like.

The blank 10 is formed from a sheet of suitable substrate. It is to be understood that, as used herein, the term “suitable substrate” includes all manner of foldable sheet material such as paperboard, corrugated board, cardboard, plastic, combinations thereof, and the like. It should be recognised that one or other numbers of blanks may be employed, where suitable, for example, to provide the carrier structure described in more detail below.

The packaging structure or carton 90 described herein may be formed from a sheet material such as paperboard, corrugated board, plastic, combinations thereof, and the like. The paperboard may be selected from any conventional paperboard, for example, ranging in weight upwardly from about 10pt. to about 28pt. (0.0287-0.7mm). An example of such paperboard is SBS board (solid bleached sulfate paperboard coated on one side, trade name PrintKote®) or CNK® board (Coated Natural Kraft® -a coated natural kraft board, trade name CarrierKote™ and CustomKote™) manufactured by WestRock© Company. The paperboard substrate may be a bleached or unbleached board. The board may be coated on at least one side or may be uncoated. The corrugated board may be selected from that of almost any flute size. Optionally, the corrugated board may be a board material such as but not limited to Έ-flute”. The sheet material may be made of or coated with materials to increase its strength. An example of such a sheet material is tear-resistant NATRALOCK® paperboard made by WestRock Company. It should be noted that the tear resistant materials may be provided by more than one layer, to help improve the tear- resistance of the package. Typically, one surface of the sheet material may have different characteristics to the other surface. For example, the surface of the sheet material that faces outwardly from a finished package may be particularly smooth and may have a coating such as a clay coating or other surface treatment to provide good printability. The surface of the sheet material that faces inwardly may, on the other hand, be provided with a coating, a layer, a treatment or be otherwise prepared to provide properties such as one or more of tear-resistance, good glue-ability, heat sealability, or other desired functional properties.

In the illustrated embodiment, the blank 10 is configured to form a carton or carrier 90 for packaging an exemplary arrangement of exemplary articles. In the illustrated embodiments, the arrangement is an m x n matrix or array, having one rows (m=1) and two columns (n=2); in the illustrated embodiment one rows of two articles are provided, and the articles are bottles.

The blank 10 is foldable to form a package 90 as illustrated in Figures 4 and 5.

Turning to the construction of the carton 90 as illustrated in Figures 1B to 1D, the carton 90 can be formed by a series of sequential folding operations. The folding process is not limited to that described below and may be altered according to particular manufacturing requirements.

The second inner top panel 22 is folded, with respect to the first inner top panel 20 about fold line 21 , to be brought into face contacting relationship therewith as shown in Figure 1 B.

Glue or other adhesive treatment is applied to the second outer top panel 14. Alternatively, glue or other adhesive treatment may be applied to the second inner top panel 22.

The first inner top panel 20, second inner top panel 22, and the second base panel 18 are folded with respect to the first base panel 16, about fold line 17, to bring the first base panel 16 into face contacting relationship with the second base panel 18 and the second outer top panel 14 into face contacting relationship with second inner top panel 22 as shown in Figure 1C. The second outer top panel 14 is secured to the second inner top panel 22. Glue or other adhesive treatment is applied to the first inner top panel 20 as shown in Figure 1C. Alternatively, glue or other adhesive treatment may be applied to the first outer top panel 12.

The first outer top panel 12 is folded with respect to the second outer top panel 14, about fold line 33, as shown in Figure 1D. The first outer top panel 12 is brought into face contacting relationship the second outer top panel 14. The first outer top panel 12 is secured to the second outer top panel 14.

In this way a flat collapsed tubular structure 10B is formed.

A flat collapsed carrier 10B is thereby formed, as shown in Figure 1 D, the flat collapsed carrier 10B can be readily shipped or distributed in the flat condition to a plant for erecting and loading with primary product containers.

The flat collapsed carrier 10B can be opened into a tubular structure by unfolding the base wall 16/18 to bring the first and second base panel 16, 18 into a substantially coplanar relationship with each other.

Once the carrier 90 is erected, the carrier 90 may be loaded with a group of articles B; in the embodiment illustrated in Figures 2, 3 and 4 two articles B arranged in a 1 x 2 array.

The group of articles B may be loaded through the base wall 16/18, upper portions of the articles B, the upper portion may include a cap or end closure C and optionally a neck flange F, are inserted into the carrier 90. Each article retention structure RT receives a portion of a respective article B. The teeth 40 are displaced inwardly of the tubular structure. The teeth 40 may optionally engage an article B below a flange F (see Figure 4), projection, under cut or other suitable feature of the article B or its end closure C.

The upper portion of the articles B is received in openings in the inner and outer top walls 20/22, 12/14 provided by the first and second article receiving apertures A5, A1. Each second article receiving aperture A1 is disposed in vertical alignment with a respective one of the first article receiving apertures A5. The opposed edges E7 of the second article receiving aperture A1 and the opposed edges E8 of first article receiving apertures A5 engage an article below the flange F (see Figure 4), projection, under cut or other suitable feature of the article B or its end closure C. In the illustrated embodiment, the opposed edges E7, E7 and E8, E8 are primary bottle engaging edges and thus the inner and outer top walls 20/22, 12/14 bear primarily the load of the bottles.

In the illustrated embodiment, the tubular structure does not extend above the uppermost end of the article B or its end closure C, best shown in Figure 4. In other words, the hinged connection, fold line 13, between the first and second outer top panels 12, 14 defines a ridge or peak which is disposed at an elevation below the uppermost end of the article B or its end closure C.

The second inner and first outer top panel 22, 14 and the first base panel 16 define an angle therebetween, the angle is an acute angle.

The first inner and second outer top panel 20, 12 and the second base panel 18 define an angle therebetween, the angle is an acute angle.

A user may grasp the carrier 90 to carry the articles B. In doing so the first handle flap 60A and the second handle flap 60B can be folded out of the plane of the respective one of the first and second outer top panels 12, 14 to which they are hingedly connected.

The first handle flap 60A is received in a recess in the tubular structure provided by the second handle aperture A4, in the erected condition the second handle aperture A4 defines or provides a recess in the second base panel 18 and a recess in the first inner top panel 20.

The second handle flap 60B is received in a recess in the tubular structure provided by the first handle aperture A3 and by the recess R, in the erected condition the first handle aperture A3 defines or provides a recess in the first base panel 16 and the recess R provides a recess in the second inner top panel 22.

Edges of the first handle flap 60A, defined by the outlines 63A, may engage with portions of second and third non-linear or curved edge E2, E3. Edges of the second handle flap 60B, defined by the outlines 63B, may engage with portions of first and fourth non-linear or curved edge E1, E4.

A region of the base wall 16/18 disposed between the article retention structure RT and defined at least in part between the first and second handle apertures A3, A4 may be deformed or displaced upwardly. The region of the base wall 16/18 may bow upwardly at its centre or middle such that the base wall 16/18 appear concave when viewed from below.

An inner surface of the first and second handle flaps 60A, 60B may be brought into contacting relationship with the respective one of the first and second non-linear or curved edges E1 , E2.

In use the inner surfaces of the first and second handle flaps 60A, 60B may be folded sufficiently to be brought into substantially face-to-face relationship with the base wall 16/18.

It can be appreciated that various changes may be made within the scope of the present invention. For example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape.

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, 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 or a severance line or both. 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.
