Referring to Figure 1 there is shown a plan view of a blank 10 that can be assembled into a carton 90 (see Figures 5 and 6) which is capable of accepting an input of primary products such as, but not limited to, bottles or cans, hereinafter referred to as articles A.

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 for engaging, carrying, and/or dispensing articles, such as 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. Exemplary containers include bottles (for example metallic, glass or plastics bottles), cans (for example aluminium cans), tins, pouches, packets and the like.

The blanks 10, 1 10 are 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, Kraft board, corrugated board, cardboard, plastic, combinations thereof, and the like. It should be recognized that one or other numbers of blanks may be employed, where suitable, for example, to provide the carton 90, 190 described in more detail below.

In the exemplary embodiment, the blank 10 is configured to form a carton 90 optionally of the fully enclosed type, for packaging an exemplary arrangement of exemplary articles. In a first illustrated exemplary embodiment, the carton 90 is configured to accept articles in a main compartment or chamber in a 2 x 3 matrix or array arrangement, and comprises a pocket expandable to accept 3 additional articles in a 1 x 3 matrix or array arrangement; and the articles are 25cl aluminium cans. In a second illustrated exemplary embodiment, the carton 190 is configured to accept articles in a main compartment in a 2 x 3 matrix or array arrangement, and comprises a pocket expandable to accept 2 additional articles in a 1 x 2 matrix or array arrangement. The blanks 10, 1 10 can be alternatively configured to form a carrier for packaging other types, number and size of article and/or for packaging articles in a different arrangement or configuration.

Referring back to Figure 1 , it can be seen that the blank 10 comprises a plurality of main panels, optionally arranged in a linear series, that form enclosing walls of the carton 90. Optionally, the series of main panels includes: a first outer side panel 12, a top panel 14, a second side panel 16, a bottom panel 18 and a first inner side panel 20. The first outer panel 12, top panel 14, second side panel 16, bottom panel 18 and first inner side panel 20 are hinged together in series by fold lines 13, 15, 17 and 19 respectively. A pocket base panel 36 is hinged to the first outer side panel 12 by a fold line 35.

A first series of end flaps is provided at a first end of the blank 10. The first series of end flaps includes: a first end flap 22a, hinged by a fold line 21 a to a first end of the first outer side panel 12; a second end flap 24a, hinged by a fold line 23a to a first end of the top panel 14; a third end flap 26a, hinged by a fold line 25a to a first end of the second side panel 16; and a fourth end flap 28a, hinged by a fold line 27a to a first end of the bottom panel 18. In use, the first, second, third and fourth end flaps 22a, 24a, 26a, 28a form a first end wall 22a/24a/26a/28a of the carton 90.

A second series of end flaps is provided at a second end of the blank 10. The second series of end flaps includes: a fifth end flap 22b, hinged by a fold line 21 b to a second end of the first outer side panel 12; a sixth end flap 24b, hinged by a fold line 23b to a second end of the top panel 14; a seventh end flap 26b, hinged by a fold line 25b to a second end of the second side panel 16; and an eighth end flap 28b, hinged by a fold line 27b to a second end of the bottom panel 18. In use, the fifth, sixth, seventh and eighth end flaps 22b, 24b, 26b, 28b form a second end wall 22b/24b/26b/28b of the carton 90.

The blank 10 comprises a collapsible pocket feature P (see Figure 6) which can be expanded to increase the load capacity of the carton 90. The pocket feature P is formed in part in the first outer side panel 12 and in part in the first inner side panel 20.

The first outer side panel 12 comprises a front wall 30 of the pocket feature P. The front wall 30 is struck from the first outer side panel 12 and is defined in part by a first outline 29e, a second outline 29d, a third outline 29c, a fourth cut line 29b and a weakened line of severance 29a. Weakened line of severance 29a comprises at least one frangible connection F; in the illustrated embodiment six frangible connections F are provided. The weakened line of severance 29a is interrupted by an aperture A1. The aperture A1 forms a tear initiation point for a user to sever the weakened line of severance 29a and deploy the pocket feature P.

The front wall 30 is substantially "T" shaped. The front wall 30 extends across the first outer side panel 12 from a first edge defined by fold line 21 a to a second edge defined by fold line 21 b. Third outline 29c is collinear with fold line 21 a and fourth cut line 29b is collinear with fold line 21 b. The pocket base panel 36 is hinged to the front wall 30 by fold line 35. Optionally, the front wall 30 comprises a first fold line 31 and a second fold line 33. First fold line 31 defines in part an optional first bevel panel 32 and second fold line 33 defines in part an optional second bevel panel 34.

The first inner side panel 20 comprises a securing flap 40, configured to be secured to the pocket base panel 36. The securing flap 40 comprises a fold line 41 which defines in part a first portion 42 for being secured to the pocket base panel 36. The first inner side panel 20 comprises a second securing flap 46a and a third securing flap 46b. The second securing flap 46a is hingedly connected to a first pocket side panel 44a by a fold line 43a. The second securing flap 46a is defined in part by severable line 47a defined in the first inner side panel 20, such that the second securing flap 46a and the first pocket side panel 44a are detachable from the first inner side panel 20. The third securing flap 46b is hingedly connected to a second pocket side panel 44b by a fold line 43b. The third securing flap 46b is defined in part by severable line 47b defined in the first inner side panel 20 such that the third securing flap 46b and the second pocket side panel 44b are detachable from the first inner side panel 20.

The first pocket side panel 44a comprises a pair of tabs 50a extending from opposing side edges. The tabs 50a are disposed proximate a free end edge of the first pocket side panel 44a. Each of the tabs 50a provides a shoulder each having an engagement edge 51 a. The engagement edges 51 a define end stops limiting the travel of the first and second pocket side panels 44a, 44b.

Optionally, the bottom panel 18 comprises an opening A2, which exposes to view a portion of one or more articles disposed therein. The blank 10 in Figure 1 is shown with an inside surface (sometimes with bleached paperboard, referred to as the "brown side") facing outwards.

To form a part-assembled, flat-form structure as shown in Figure 4, the bottom panel 18 and first inner side panel 20 are folded about fold line 17, as indicated by direction arrow D1 in Figure 2, into face contacting relationship with the second side panel 16 and the top panel 14 respectively.

Glue G or other adhesive treatment is applied to the first, second and third securing flaps 40, 46a, 46b and to the first inner side panel 20.

The pocket base panel 36 is folded about fold line 35, as indicated by direction arrow D2 in Figure 3, into face contacting relationship with the first outer side panel 12.

The blank 10 is then folded about fold line 13, as indicated by direction arrow D3 in Figure 4, to bring the first outer side panel 12 into overlapping relationship with the first inner side panel 20. The first outer side panel 12 is secured to the first inner side panel 20. The pocket base panel 36 is brought into face contacting relationship with the first securing flap 40. The pocket base panel 36 is secured to the first securing flap 40.

The resulting structure is a part-assembled, flat-form carton as shown in Figure 4. The part- assembled, flat-form carton can be readily shipped or distributed in its flat form.

As can be seen in Figure 2, the weakened line of severance 29a maintains a temporary connection between the front wall 30 of the pocket feature P and the adjacent portion of the first outer side panel 12. In this way, the carton 90 is less likely to become caught up on parts of the machinery used in the processing and assembly of the blanks and the processing and filling of the cartons. This may beneficially mitigate against significant down-time of machinery which can otherwise be experienced when jutting out portions of blanks or part-assembled cartons become caught or jammed in the machinery. When it is required to complete the construction of the carton 90, the part-assembled, flat-form carton can be opened out (optionally by pulling the first side panel 12/20 upwardly and away from the top panel 14).

The carton 90 is then erected to form a tubular structure open at both ends; the carton 90 can then be loaded with articles A through the one or both open ends.

To close the first open end, the first and third end flaps 22a, 26a, which form minor end flaps or dust flaps, are folded inwardly about fold lines 21 a, 25a. The second end flap 24a is folded downwardly about fold line 23a. Glue or other adhesive treatment is applied to the second end flap 24a or to the fourth end flap 28a. The fourth end flap 28a is folded upwardly about fold line 27a and secured to the second end flap 24a.

Optionally, glue or other adhesive treatment is applied to the first and third end flaps 22a, 26a so as to secure them to one or both of the second and fourth end flaps 24a, 28a.

To close the second open end, the fifth and seventh end flaps 22b, 26b, which form minor end flaps or dust flaps, are folded inwardly about fold lines 21 b, 25b. The sixth end flap 24b is folded downwardly about fold line 23b. Glue or other adhesive treatment is applied to the sixth end flap 24b or to the eighth end flap 28b. The eighth end flap 28b is folded upwardly about fold line 27b and secured to the sixth end flap 24b. Optionally, glue or other adhesive treatment is applied to the fifth and seventh end flaps 22b, 26b so as to secure them to one or both of the sixth and eighth end flaps 24b, 28b.

The assembled carton 90 is shown in Figure 5. The pocket feature P is stowed in a collapsed form in a first stowed position.

The pocket feature P can be deployed to an expanded condition as shown in Figure 6. A user can engage the front wall panel 30 via the aperture A1 and pull the front wall panel 30 away from the first inner side wall 20, as indicated by direction arrow D4 in Figure 6. The pocket feature P in the deployed condition can receive one or more articles A. In the illustrated embodiment the pocket feature P receives three additional articles A similar to those disposed within the main carton compartment.

When the pocket feature P is deployed the second and third securing flaps 46a, 46b are separated from the first inner side panel 20 by severing the weakened lines 47a, 47b. The first and second pocket side walls 44a, 44b are linearly translatable or moveable within respective openings O defined in the composite side wall 12/20; that is to say, the first and second pocket side walls 44a, 44b may be slid within the respective openings defined in the composite side wall 12/20. The composite side wall 12/20 is formed from the first inner and first outer side panels 12, 20. The openings are defined in part by a respective one of the cut lines 29c, 29b and in part by a respective one of the severable lines 47a, 47b. The tabs 50a/50b provide end stops preventing the first and second pocket side walls 44a, 44b being fully withdrawn through the respective one of the opening in the composite side wall 12/20. When the pocket feature P is in the second deployed position each of the opposing side walls is at least partially disposed outside the main carton compartment or chamber.

The base wall 36/40 is simultaneously erected as the first and second pocket side walls 44a, 44b are drawn through the respective one of the openings in the composite side wall 12/20. The pocket base panel 36 is unfolded about fold line 35 so as to be substantially perpendicular to the front wall panel 30. The first securing flap 40 is unfolded about fold line 39, which is optionally collinear with fold line 19. The first securing flap 40 is folded about fold line 41 so as to bring an inner surface of the first portion 42 into face to face relationship with the other portion of the first securing flap 40. The frangible connections F are destroyed when the pocket feature P is first deployed. However, it will be appreciated that the pocket feature P can be returned to the stowed condition if desired. Optionally, the carton 90 may comprise a first indicia 92. The first indicia 92 is provided on the composite side wall 12/20. A first portion 98 of the first indicia 92 is provided on the at least one of the first bevel panel 32, front wall panel 30 and second bevel panel 34. In the embodiment illustrated in Figures 5 and 6 the first portion 98 of the first indicia 92 is provided in part on the front wall panel 30 and in part on the second bevel panel 34. A second portion 96 of the first indicia 92 is provided on a region of the first outer side panel 12 adjacent to the front wall panel 30 and in part on the second bevel panel 34. The first indicia 92 is therefore provided on both sides of the weakened line of severance 29a. The first indicia 92 is optionally provided on both sides of the fold line 33. In other embodiments, the first indicia 92 may be provided on both sides of fold line 31. In still other embodiments the first portion 98 of the first indicia 92 may be provided only on one of the first bevel panel 32, front wall panel 30 and second bevel panel 34.

The first indicia 92 may contain information characteristic of the package 90 when the pocket feature P is in the stowed condition. For example, but not limited to, the information may relate to the sales price of the package 90 the pocket feature P is in the stowed condition.

The information provided on the indicia may directly indicate the sales price or may contain a code which identifies the package 90. The code may be associated with pricing information in a point of sale system or computer. For example, the code may take the form of a barcode symbol such as Universal Product Code (UPC). Optionally, the code may be machine readable by for example, but not limited to, optical scanning such as a barcode, the barcode may be linear or one-dimensional in which data is represented by varying the width and spacing of parallel lines or may two-dimensional codes or matrix barcodes for example employing rectangles, dots, hexagons and/or other geometric patterns in two dimensions.

When the pocket feature P is deployed the first indicia 92 may be separated into two or more parts which are spaced apart from one another.

When the pocket feature P is in the deployed condition the first indicia 92 may be altered so as to indicate that the information provided is no longer applicable or to be used. When the pocket feature P is in the deployed condition the first indicia 92 may be damaged or destroyed such that is becomes unusable or unreadable.

At least a portion of the first indicia 92 may be obscured from view when the pocket feature P is loaded with additional articles A.

In further alternative embodiments the first indicia 92 may be provided in alternative locations. A first alternative location 93 and a second alternative location 94 are shown in Figure 5. In the first alternative location 93 the first indicia is provided in part on the first outer side panel 12 and in part on the first bevel panel 32 and in part on the front wall panel 30, however it will be appreciated that the first indicia may be disposed in part on the first outer side panel 12 and in part on only one of the first bevel panel 32 and the front wall panel 30.

In the second alternative location 94 the first indicia is provided in part on the first outer side panel 12 and in part on the second bevel panel 34 and in part on the front wall panel 30, however it will be appreciated that the first indicia may be disposed in part on the first outer side panel 12 and in part on only one of the second bevel panel 34 and the front wall panel 30. The carton 90 may comprise a second indicia 99 as shown in Figure 6. The second indicia 99 is visible when the pocket feature P is deployed. In the embodiment of Figure 6 the second indicia is provided or located upon the first pocket side wall panel 44a. The second indicia 99 becomes exposed to view when the pocket feature is deployed. In the illustrated embodiment this is achieved when the first pocket side wall panel 44a is moved from a first position in which it is disposed internally of the main carton compartment to a second position in which a portion of the first pocket side wall panel 44a is disposed externally of the main carton compartment. In other embodiments the second indicia 99 may be provided additionally or alternatively upon a region of the second pocket side wall panel 44b which becomes disposed external to the main compartment of the carton 90 when the pocket feature P is deployed. In still other embodiments the second indicia 99 may be provided upon the base wall panel 40 or portion of the securing flap 40.

The second indicia 99 may contain information characteristic of the package 90 when the pocket feature P is in the deployed condition. For example, but not limited to, the information may relate to the sales price of the package 90 when the pocket feature P is in the deployed condition. The information provided on the second indicia 99 may directly indicate the sales price or may contain a code which identifies or is indicative of the pocket feature P as being in the deployed condition.

In this way the package 90 may comprise two different product or price codes such that a point of sale system determines the correct sale price and consequently the state (stowed or deployed) in which the package may be determined.

The first and second indicia 92, 99 may be printed directly upon the material substrate forming the carton 90 or may be provided on a separate label or other printed material. When a separate label is employed the label may be secured adhesively to the carton 90. In the case where a label is employed for providing the first indicia 92 the label may comprise a perforated line or be otherwise weakened such that it is divisible into at least two parts when the pocket features deployed. The label may be used in addition to, or as an alternative to, the weakened line of severance 29a and the frangible connections F for holding the pocket feature P in the stowed condition. The label may be applied to portion of the first outer side panel 12 and to a portion of at least one of the first bevel panel 32, the second bevel panel 34 and the front wall panel 30.

Referring now to Figures 7 to 13, there is shown an additional embodiment of the present disclosure. In the second illustrated embodiment like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix "100" to indicate that these features belong to the second embodiment. The additional embodiment shares many common features with the previous embodiment and therefore only the differences from the embodiment illustrated in Figures 1 to 6 will be described in detail.

Referring to Figure 7, it can be seen that the blank 1 10 comprises an optional linear series of main panels that form enclosing walls of the carton 190. Optionally, the series of main panels includes: a first outer side panel 1 12, a top panel 1 14, a second side panel 1 16, a bottom panel 1 18 and a first inner side panel 120.

In the deployed condition the first indicia 92, 192 may be obscured for example by articles A disposed within the pocket feature P.

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 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 otherto 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 terms "severance line", "weakened line", and "frangible line" refer to all manner of lines that facilitate separating portions of the substrate from one another or that indicate optimal separation locations. Severance lines may be frangible or otherwise weakened lines, tear lines, cut lines, or slits.

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 cut line, 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 cut line, an interrupted cut line, 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 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.
