Abstract
Description
- The invention relates to a consumer package or carton which accommodates a group of articles such as bottles or cans. More specifically, but not exclusively, the group of articles are arranged in the rows such that a void is present at each end of the carton intermediate the outer article rows. The carton incorporates a carrying handle in the form of a 'wrap-around' band, preferably of a plastics material, which includes a portion which spans the void at each end of the carton and there provides a length of the band which is incorporated into the carton to provide a handle which may be readily grasped. The carton is configured so as to have a first polygonal shape at a first, upper, end of the carton and to have a second, different, polygonal shape at a second, lower, end of the carton.
- In the field of packaging it is often required to provide consumers with a package comprising multiple primary product containers. Such multi-packs are desirable for shipping and distribution purposes and for the display of promotional information.
- For cost and environmental considerations, it is preferable if such cartons are formed from as little material as possible and cause as little wastage as possible in the materials from which they are formed. Another consideration is the strength of the packaging and its suitability for holding and transporting large weights of articles.
- In the packaging industry automatic, high-speed processing of the blanks that form the cartons, part-formed cartons and filled cartons is required. In designing packages, consideration needs to be given to automatic, high-speed processing and compatibility with existing automatic machinery.
- It is desirable to reduce movement of the primary product container within the package. This may reduce or eliminate impact between adjacent articles. In this way, the likelihood of damage to the primary product or the primary product container is reduced.
- It is also desirable to provide a carrying handle such that a user may transport the carton. Further, it is desirable to provide a dispensing feature to enable the user to easily withdraw an article from the carton.
- The present invention seeks to overcome or at least mitigate the problems of the prior art by providing a carton having a brace or bumper feature for reducing movement of articles within the carton.
- An aspect of the invention provides a carton for packaging one or more articles having a plurality of panels defining walls of a tubular structure. The carton comprises at least one end closure panel for at least partially closing an end of the tubular structure. The plurality of panels includes a first panel forming a first wall of the tubular structure and a second panel forming a second, opposing, wall of the tubular structure. The first panel comprises a first polygonal shape and the second panel comprise a second, different, polygonal shape.
- Optionally, the first polygonal shape is one shape selected from the group of shapes including a quadrilateral, a square and a rectangle.
- Optionally, the second polygonal shape is one shape selected from the group of shapes including an octagon and a hexagon.
- Optionally, the first polygonal shape comprises a first integer number of sides and the second polygonal shape comprises a second integer number of sides. The second integer number is greater than the first integer number.
- Optionally, the first wall comprises at least one corner which overhangs so as to extend outwardly beyond an edge of the second wall.
- Optionally, the carton comprises a plurality of end closure panels shaped and arranged to form an end wall substantially closing an open end of the tubular structure.
- Optionally, the first wall is coupled to the second wall by a third wall. The third wall comprises first and second end edges, at least a portion of the first and second end edges being configured so as to be divergent with respect to each other.
- Optionally, a package comprises a carton and encloses a group of uniform articles such as bottles or cans disposed in a plurality of rows. The articles are arranged or configured such that a void is formed in at least one side of said carton. The carton is encircled by a close fitting band disposed intermediate the first wall and the second wall. The band spans the void, and a portion of the carton spans the void, the portion of the carton and the portion of the band together providing a carrying handle.
- A further aspect of the invention provides a blank for forming a carton. The blank comprises a plurality of panels for forming walls of a tubular structure. The blank comprises at least one end closure panel for at least partially closing an end of the tubular structure. The plurality of panels includes a first panel for forming a first wall of the tubular structure and a second panel for forming a second, opposing, wall of the tubular structure.

transverse fold line 19a so that it overlies the securingpanel 12. - The second upper
side wall panel 20a is secured to the securingpanel 12. - The blank 10 thus pre-formed may then be supplied to, for example a canning or bottling plant for erecting, loading and finally closing to form the completed
carton 90. - Once the carton has been erected into its tubular form it can be filled with cans or bottles in the configurations shown in
Figure 2 , for example, in which the bottles comprising the center rows are disposed intermediate a pair of adjacent bottles in each of the next adjacent outer rows, thereby creating a central recess at each end of the carton. Each of the ends of the carton is then closed in the following manner. - The top corner
end closure panel 24a is folded downwardly relative totop panel 14 aboutfold line 23a, the initial folding action of which may be instigated by the displacing inwardly of the tubular structure each of thegusset panels - This folding action is accompanied by inward folding of the

carton 90 are configured and arranged such that the first and second side walls 16, 20 of thecarton 90 are tapered towards each other as they approach thetop panel 14 of thecarton 90. In this way thecarton 90 comprises a 'gable top'. The end closure panels which form end walls of the carton may be similarly arranged such that first and second end walls of thecarton 90 are tapered towards each other as they approach thetop panel 14. - However, due the fact that the
base panel 18 comprises beveled corners, so as to be octagonal in shape, the corners of thetop panel 14 overhang or project beyond the beveled corners of thebase panel 18, as can be seen inFigures 5A, 5B . - The first upper
side wall panel 16a comprises end edges defined by thefold lines upper side panel 16a increases as it approaches thetop panel 14. The second upper side panel 16A is similarly arranged. - This change in shape between the
base panel 18 and thetop panel 14 provides that the lower regions of thecarton 90 form a close fit about the group of articles A whilst at the same time allowing the dispensing feature in thetop panel 14 to be optimized to increase accessibility to the articles disposed about the periphery of the group of articles A. The location of the bases of the articles A relative to thebase panel 18 and thetop panel 14 is shown inFigure 2 . In the illustrated embodiment the articles A each comprises tapered upper portions such that the footprint of the articles, and hence the article group, is smaller proximate thetop panel 14 than thebase panel 18. - Referring now to

The plurality of panels may be arranged as a linear series hingedly connected one to the next. The carton comprises a plurality of end flaps for closing the carton. The carton comprises a first or top panel having a first polygonal shape and a second or base panel having second, different polygonal shape. The second or base panel opposes the first or top panel. The first shape may be a quadrilateral, square or rectangle. The second shape may be octagonal, hexagonal or other shape. The second shape may comprise more sides than the first shape.
- The first or top panel may comprise corner portions which overhang or extend outward over or beyond the second or base panel.
- Embodiments of the present disclosure provide a carton having a plurality of panels defining walls of a tubular structure. The tubular structure comprises a first wall and a second opposing wall. Optionally, the first wall is substantially rectangular in shape and the second wall is non-rectangular, optionally octagonal in shape. The carton comprises an end wall which at least partially closes an open end of the tubular structure. Optionally, both open end is closed at least in part by an end wall. The end wall is formed from a first set of closure flaps connected to the first wall and from a second set of closure flaps connected to the second wall respectively. The first set of closure flaps includes a generally trapezoidal end flap hingedly connected to the first wall and a pair of opposite wing flaps hingedly connected to the trapezoidal flap along wing flap fold lines respectively. Each of the wing flaps is secured to at least one of the second set of end closure flaps. Each of the wing flaps has an end edge which defines an acute angle with respect to the respective wing flap fold line. The end edge of each wing flap and the respective wing flap fold line are arranged such that they converge toward an adjacent end of a fold line between the first wall and a side wall which extends between the first wall and the second wall. The first set of closure flaps includes each of the pair of top corner
end closure panels end closure panel 22a; 122a; 222a. The second set of closure flaps includes each of the pair of bottom cornerend closure panels end closure panel 30a; 130a; 230a. - 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 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 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.
