The carton 190 is suitable for containing and carrying a group of primary products such as, but not limited to, bottles or cans, hereinafter referred to as articles B, as shown in FIG. 6. The third blank 110 and second blank 70 together form a secondary package for packaging at least one primary product container or package.

Referring again to FIG. 5, the third blank 110 comprises a plurality of main panels 114, 116, 118 hinged one to the next in a linear series. The plurality of main panels 114, 116, 118 of the blank 110 form walls of a carton 190 in a set up condition. The third blank 110 comprises a first wall panel 114, which forms a first upper side wall of the carton 190 (see FIG. 6). The first wall panel 114 is hinged to a second wall panel 116 by a hinged connection such as a fold line 115. The second wall panel 116 forms a top wall of the carton 190 as shown in FIG. 6. The second wall panel 116 is hinged to a third wall panel 118 by a hinged connection such as a fold line 117. The third wall panel 118 forms a second upper side wall 118 of the carton 190 as shown in FIG. 6.

The blank 110 comprises an alternative handle structure. This structure comprises a handle aperture HA struck from within the second wall panel 16. The handle aperture HA is substantially rectangular in shape, however in alternative embodiment other shapes may be employed. The first handle reinforcing panel 112 comprises a central strap portion 112A which is configured to be in vertical registry with the handle aperture HA. The second handle reinforcing panel 120 is likewise configured with a central strap portion which is disposed in vertical registry with the handle aperture HA and the central strap portion 112A of the first handle reinforcing panel 112. The first and second handle reinforcing panels 112, 120 together form a handle strap which can be withdrawn through the handle aperture HA. The second handle reinforcing panel 120 may be secured to the first handle reinforcing panel 112, for example, but not limited to, by employing glue or other adhesive treatment.

The first and second handle reinforcing panels 112, 120 may be unsecured to the second top panel 116 so as to be free to move with respect thereto. Similarly portions of the first, second, third and fourth end reinforcing panels 122a, 146a, 122b, 146b may be unsecured to the respective ones of the first and second upper end closure panels 134a, 134b so as to be free to move with respect thereto.

As shown in FIG. 6 the handle strap 112a protrudes through the handle aperture HA. The handle strap 112a may be configured to automatically protrude through the handle aperture HA when the first and second upper end closure panels 134a, 134b are folded with respect to the second wall panel 116. This may be achieved by offsetting the fold line between the first handle reinforcing panel 112 and the first end reinforcing panel 122a with respect to the fold line 135a. Similarly, the fold line between the first handle reinforcing panel 112 and the third end reinforcing panel 122b may be offset with respect to the fold line 135b, the fold line between the second handle reinforcing panel 120 and the second end reinforcing panel 146a may be offset with respect to the fold line 135a and the fold line between the second handle reinforcing panel 120 and the fourth end reinforcing panel 146b may be offset with respect to the fold line 135b. In this way the handle strap 112a may be configured to be longer in length dimension than the second wall panel 116 so that the handle strap 112a is forced through the handle aperture HA when the carton 190 is assembled.

The end portion of the handle strap 112a may be arranged to broaden towards the respective adjacent end reinforcing panel 122a, 122b, 146a, 146b. In this way the end portions of the handle strap 112a restrict the extent to which the handle strap 122a can be withdrawn through the handle aperture HA.

Referring to FIG. 11, there is shown a plan view of a blank 410 for forming a carton or carrier (not shown). The blank 410 is unitary, that is to say the second blank 70 of FIG. 2 is not required to form a complete carton. The blank 410 comprises a first base wall panel 408a and a second base wall panel 408b which together form a composite base wall 408a/408b of the carton.

The sixth blank 410 comprises a plurality of main panels 408a, 414, 416, 418, 408b hinged one to the next in a linear series. The plurality of main panels 408a, 414, 416, 418, 408b of the blank 410 form walls of a carton in a set up condition. The first base wall panel 408a is hinged to a first wall panel 414 by a hinged connection in the form of a fold line 411a. The first wall panel 414 forms a first side wall of the carton. The first wall panel 414 is hinged to a second wall panel 416 by a hinged connection such as a fold line 415. The second wall panel 416 forms a top wall of the carton. The second wall panel 416 is hinged to a third wall panel 418 by a hinged connection such as a fold line 417. The third wall panel 418 forms a second side wall 418 of the carton. The third wall panel 418 is hinged to a second base wall panel 408b by a hinged connection in the form of a fold line 411b.

In order to accommodate the first and second base wall panels 408a, 408b the position of the fold lines 427a, 427b, 447a, 447b must be adjusted. The dimensions of the first, second, third and fourth inner anchor panels 428a, 428b, 440a, 440b; the first, second, third and fourth outer anchor panels 426a, 426b, 442a, 442b; and the first, second, third and fourth bridging panels 424a, 424b, 444a, 444b are increased in length to accommodate the first and second base wall panels 408a, 408b between the second wall panel 416 and the respective one of the first and second handle reinforcing panels 412, 420.

The distance d/2 between the fold line 427a and the proximal edge of the handle strap portion defined in the second wall panel 416 should be around one half the distance d between the fold line 415 and the proximal edge of the central portion of the first handle reinforcing panel 412. In the embodiment illustrated in FIG. 11, a cutaway or recess is struck from an edge of the first handle reinforcing panel 412. This recess is created by the aperture A1, see FIG. 1. It will be appreciated that a similar relationship for the fold lines 427b, 447a, 447b is required.

The present disclosure provides a carton for packaging one or more articles. The carton comprises a first side wall, a second side wall and a top portion. The carton may be formed from one unitary blank or from two or more distinct blanks; the top portion may be formed from one of the two or more distinct blanks. The top portion comprises or is defined in part by a top wall panel, formed from the second wall panel and a first upper end closure panel. The first upper end closure panel is hinged to the top wall panel along a first end edge thereof. The carton comprises a carrying handle defined in the top portion. A first gusset panel is hinged to the first upper end closure panel along a first side edge. A first anchor panel is hinged to the first gusset panel and to the first side wall. The first anchor panel is folded into a face to face relationship with the first side panel so as to secure the first upper end closure panel in a closed condition. The carton comprises a first handle reinforcing structure disposed at least in part about the carrying handle. Optionally, the first handle reinforcing structure is defined in part by a handle reinforcing panel and in part by at least one end reinforcing panel. The first handle reinforcing structure is coupled to the first anchor panel by two or more connecting panels. The connecting panels may be provided by one of the bridging panels and the respective one of the outer anchor panels hinged thereto.

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 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.
