Turning to the construction of the carton 90 as illustrated in
In order to form the carton 90, in a first stage the blank 10 is folded to bring the inner top wall panel 12 of the first package into face contacting relationship with the first side wall panel 14 folding the first top wall panel 12 about the fold line 11.
The inner top wall panel 30 of the second package is folded about the fold line 27 to bring the inner top wall panel 30 of the second package into face contacting relationship with the first side wall panel 28.
Glue or other adhesive treatment is applied to the inner top wall panel 12 of the first package.
Glue or other adhesive treatment is applied to the inner top wall panel 30 of the second package.
In alternative embodiments glue or other adhesive treatment is applied to the corresponding portions of each of the outer top wall panels 20, 22 of the first and second packages respectively.
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.

Glue or adhesive treatment is applied to an outer surface of the third end closure panel 44a. In an alternative embodiment glue or adhesive treatment is applied to an inner surface of the first end closure panel 40a and/or fourth end closure panel 46a. The first end closure panel 40a is folded about fold line 39a and brought into contact with the third end closure panel 44a such that part of the first end closure panel 40a is in overlapping relationship with part of the third end closure panel 44a and is secured and affixed thereto. The fourth end closure panel 46a, which is secured to the inner surface of the first end closure panel 40a is folded about arcuate fold lines 47a, simultaneously with the first end closure panel 40a being folded about fold line 39a.
A second end of the second package is closed by folding the sixth end closure panel 42b about fold line 41b. Glue or other adhesive treatment may be applied to an outer surface of the sixth end closure panel 42b. In alternative embodiments the glue or adhesive treatment may be applied to an inner surface of the corresponding regions of the fifth, seventh and eighth end closure panels 40b, 44b, 46b. The seventh end closure panel 44b is folded about the fold line 43b and optionally secured to the sixth end closure panel 42b. Glue or adhesive treatment is applied to an outer surface of the seventh end closure panel 44b. In an alternative embodiment glue or adhesive treatment is applied to an inner surface of the fifth end closure panel 40b and/or to an inner surface of the eighth end closure panel 46b. The fifth end closure panel 40b is folded about fold line 39b and brought into contact with the seventh end closure panel 44b such that a portion of the fifth end closure panel 40b is in overlapping relationship with a portion of the seventh end closure panel 44b and is secured thereto. The eighth end closure panel 46b, which is secured to the inner surface of the fifth end closure panel 40b is folded about arcuate fold lines 47b, simultaneously with the fifth end closure panel 40b being folded about fold line 39b.
In some embodiments one end of the tubular structure may be closed before loading articles through a remaining open end of the tubular structure.
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 package 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 U. In this way, when the consumer U 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
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”, “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. A fold line is typically a scored line, an embossed line, or a debossed line. Any reference to “hinged connection” or “fold line” should not be construed as necessarily referring to a single fold line only; indeed it is envisaged that a hinged connection can be formed from any one or more of the following: a short slit, a frangible line or a fold line without departing from the scope of the invention.
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.
It should be understood that hinged connection, 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, and 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.
