Referring now to FIGS. 5 and 6 , 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 first embodiment and therefore only the differences from the embodiment illustrated in FIGS. 1 to 4 will be described in detail.
Referring to FIG. 5 , there is shown a plan view of a third blank 110; together with the second blank 70 of FIG. 2 , the third blank 110 forms a carton or carrier 190, as shown in FIG. 6 . 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 122 a, 146 a, 122 b, 146 b may be unsecured to the respective ones of the first and second upper end closure panels 134 a, 134 b so as to be free to move with respect thereto.
As shown in FIG. 6 the handle strap 112 a protrudes through the handle aperture HA. The handle strap 112 a may be configured to automatically protrude through the handle aperture HA when the first and second upper end closure panels 134 a, 134 b 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 122 a with respect to the fold line 135 a. Similarly, the fold line between the first handle reinforcing panel 112 and the third end reinforcing panel 122 b may be offset with respect to the fold line 135 b, the fold line between the second handle reinforcing panel 120 and the second end reinforcing panel 146 a may be offset with respect to the fold line 135 a and the fold line between the second handle reinforcing panel 120 and the fourth end reinforcing panel 146 b may be offset with respect to the fold line 135 b. In this way the handle strap 112 a may be configured to be longer in length dimension than the second wall panel 116 so that the handle strap 112 a is forced through the handle aperture HA when the carton 190 is assembled.
The end portion of the handle strap 112 a may be arranged to broaden towards the respective adjacent end reinforcing panel 122 a, 122 b, 146 a, 146 b. In this way the end portions of the handle strap 112 a restrict the extent to which the handle strap 122 a can be withdrawn through the handle aperture HA.

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.
