The inner top wall panel 12, first side wall panel 14 and the bottom panel 16 of the first package are folded about the fold line 15 such that the bottom panel 16 is in overlying relationship with the second side wall panel 18. This brings the inner top wall panel 12 into face contacting relationship with the outer top wall panel 20. Pressure may be applied to the first side panel 14 of the first package to secure the inner top wall panel 12 to the outer top wall panel 20.

The inner top wall panel 30, first side wall panel 28 and the bottom panel 26 of the second package are folded about the fold line 23 such that the bottom panel 26 is in overlying relationship with the second side wall panel 24. This brings the inner top wall panel 30 into face contacting relationship with the outer top wall panel 22. Pressure may be applied to the first side panel 28 of the second package to secure the inner top wall panel 30 to the outer top wall panel 22.

Glue or other adhesive treatment is applied to the first side wall panel 14 of the first package and/or to the first side wall panel 28 of the second package.

The blank 10 may then be folded about the frangible line 19 to bring the first side wall panel 14 of the first package into contacting relationship with the first side wall panel 28 of the second package.

In an alternative embodiment, the second side panel 24 of the second package may be folded with respect to the outer top wall panel 22 about the fold line 21. Simultaneously the first side wall panel 28 may be folded with respect to inner top wall panel 30 by unfolding the first side wall panel 28 about the fold line 27. The bottom wall panel 26 may be folded with respect to the first side wall panel 28 by folding about the fold line 25 to place the bottom wall panel 26 in face contacting relationship with the first side wall panel 28. Simultaneously, the bottom wall panel 26 is folded with respect to the second side wall panel 24, by unfolding the bottom wall panel 26 about the fold line 23. In this way the portion of the blank 10 forming the second package is folded into a flat collapsed state which overlies the portion of the blank 10 forming the first package which is also in folded, flat collapsed condition. This provides a carton 90, which is in a flat collapsed state in which it can be shipped and distributed to a converter plant. It will be appreciated that this alternative folding method could be readily modified to bring the portion of the blank 10 forming the first package into a flat, folded, collapsed state which overlies the portion of the blank 10 forming the second package which is also in a folded, flat, collapsed condition. These alternative methods avoid folding the blank 10 about the frangible line 19 and thus reduce the risk of the first and second packages becoming separated during assembly and filling of the carton 90.

The carton 90 may be erected into a tubular structure by engaging with a pair of adjacent walls of the carton 90 and folding said adjacent walls such that they are disposed perpendicularly with respect to each other.

The erected tubular structure is loaded with articles through one or both open ends of each package.

FIGS. 5 and 6 illustrate the first and second packages 91 in a separated condition. A retailer has severed the frangible line 19 such that the first package is separate to the second package. In those embodiments in which the first side wall panel 14 of the first package is glued to the first side wall panel 28 of the second package, the retailer severs or breaks the glue connection. In some embodiments the first side wall panel 14, 28 of the first and/or second package may comprise one or more glue locations which are surrounded by a half-cut perforation. In this way the retailer may readily, controllably and neatly tear an outer layer or skin of the substrate forming the first side wall panel 14, 28.

Once the retailer has separated the first package from the second package, the retailer rotates the first package with respect to the second package such that the end pull device of each of the first and second packages face the same direction. In this way, when the first and second packages are disposed upon a shelf (not shown), or other display apparatus, both the end pull devices E face the consumer. In this way, when the consumer wishes to withdraw one package from the shelf, they may employ the end pull device E of one of the packages located on the shelf, see FIG. 6.

Referring now to FIGS. 7 and 8, there is shown an alternative embodiment of the present invention. 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 alternative embodiment shares many common features with the first embodiment and therefore only the differences from the embodiment illustrated in FIGS. 1 to 6 will be described in any greater detail.

The blank 110 comprises a third recess R3 struck from, or otherwise defined in, the first side wall panel 114 of the first package and a fourth recess R4 struck from, or otherwise defined in, the first side wall panel 128 of the second package.

The third recess R3 is located on an end edge of the first side wall panel 114 of the first package. The third recess R3 is disposed adjacent to the fold line 111 such that in a set-up carton the third recess R3 is at substantially the same elevation as the recess R1 and the aperture A1.

The fourth recess R4 is located on an end edge of the first side wall panel 128 of the second package. The fourth recess R4 is disposed adjacent to the fold line 127 such that in a set-up carton the fourth recess R4 is at substantially the same elevation as the recess R2 and the aperture A2.

The blank 110 is constructed and erected using the method previously described with regard to the embodiment of FIGS. 1 to 6.

In this way the blank 110 forms a carton 190, see FIG. 8, in which the third recess R3 and fourth recess R4 are disposed at opposite ends of the carton. The fourth recess R4 is disposed upon the internal divider structure between the first and second package. The third recess R4 is disposed upon the internal divider structure between the first and second package.

When the first and second packages of the carton 190 are separated from each other, see the second package 191 illustrated in FIG. 9, the fourth recess R4 facilitates access to a side edge of the fifth end closure panel 140b. In this way the user U can grasp opposing side edges of the fifth end closure panel 140b.

FIGS. 9 and 10 illustrate the second package 91 of the first embodiment of FIG. 1 alongside the second package 191 of the second embodiment. In FIG. 9 a user U is employing the end pull device E by engaging opposing side of the fifth end closure panel 140b of the second package of the second embodiment whereas in FIG. 10 a user U is engaging an opposing side of the fifth end closure panel 40b of the second package of the first embodiment.

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 appreciated that the end pull device E of any of the embodiments disclosed herein may be employed in a carton which is not divisible.

It will be recognized that as used herein, directional references such as “top”, “bottom”, “front”, “back”, “end”, “side”, “inner”, “outer”, “inside”, “outside”, “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 term “weakened line of severance” or “frangible line” refers to all manner of lines that facilitate separating portions of the substrate from one another or that indicate optimal separation locations. Weakened lines of severance may be frangible or otherwise weakened lines, tear lines, cut lines, or slits.

As used herein, the term “hinged connection” refers to all manner of lines that define hinge features in a substrate of sheet material, for facilitating folding portions of the substrate with respect to one another, or otherwise for indicating optimal folding locations in the substrate. For example, a hinged connection should not be construed as necessarily referring to a single fold line only: indeed a hinged connection can be formed from one or more fold lines.

As used herein, the term “fold line” refers 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, aligned slits, a line of scores and any combination of the aforesaid options.

As used herein, the term “weakened line of severance”, “frangible line”, “severance line” or “tear line” refers to all manner of lines formed in a substrate of sheet material, that facilitate separating portions of the substrate from one another, or otherwise indicate optimal separation locations on the substrate. For example, a severance line or tear line in a substrate of sheet material is predisposed to allow a tear to propagate there along. A weakened line of severance, frangible line, severance line or tear line may be one of the following: a single cut, a single half-cut, a single slit, an interrupted cut, a score line, an interrupted score line, a line of perforations, a line of short cuts, a line of short slits, a line of short half cuts, and any combination of the aforementioned options.

It should be understood that hinged connections, weakened lines of severance, frangible lines, severance lines 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 alignment of two or more elements in an erected carton, such as a recess formed in a first of two overlapping panels and an 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 a recess in a first panel is “in registry with” an aperture in a second panel that is placed in an overlapping arrangement with the first panel, an edge of the recess may extend along at least a portion of an edge of the aperture and may be aligned, in the direction of the thickness of the first and second panels, with the aperture.

It should also be understood that the term “display apparatus” used in this application refers to, but not limited to, a shelf, a rack, a display cart and even a stack or pile of cartons of the same structure as the carton of the invention, in which the carton of the invention is included.
