The carton 90, shown in
The main panels 12, 20 form a composite top wall 12/20 when the handle structure H is in use as a carrying handle by a user and this composite top wall 12/20 is optionally, disposed adjacent to the sides of the articles. In this orientation, the composite top wall 12/20 is not disposed substantially planar to the tops or bottoms of the articles held within the carton 90. In other words, the cylindrical axis of the articles is substantially parallel with the plane of the composite top wall 12/20 of the carton 90.
The main panel 16 forms the base wall 16 when the handle structure H is in use as a carrying handle by a user. The main panel 16 may also form the base wall 16 when the articles are being dispensed from the carton 90 or when the carton 90 is at rest upon a surface such as a shelf. As such, it will be understood that descriptive terms “top”, “base”, and “side” do not necessarily limit the carton 90 to adopting a particular orientation but serve to distinguish those panels from one another. In other embodiments, the cylindrical axis of the articles may be orientated differently with respect to the composite top wall 12/20, or base wall 16, of the carton 90. For example, but not limited to, the cylindrical axis of the articles be may orientated substantially perpendicularly to the plane of the top wall 12/20, or base wall 16, of the carton 90.

The first handle opening comprises a first or inner side edge E3 and a second outer side edge E4. The first side edge E3 may be defined at least in part by the fold line 41 coupling the cushioning flap 40 to the handle strap 40a.
The first side edge E3 is reinforced, that is to say, the composite top wall 12/20 is of multiply construction along the first side edge E3. In the illustrated embodiment, the composite top wall 12/20 is a two-ply construction along the first side edge E3. The handle strap 40a provided by the first top wall panel 12 is reinforced by the reinforcing handle strap 40b provided by the second top wall panel 20.
The second side edge E4 is reinforced the composite top wall 12/20 is of multiply construction along the second side edge E4. In the illustrated embodiment, the composite top wall 12/20 is a two-ply construction along the second side edge E4.
The composite top wall 12/20 provides a two ply portion disposed between the first handle opening and an adjacent portion of the fold line 19 which defines a first side edge of the composite top wall 12/20.
The first handle opening therefore provided two opposing side edges E3, E4 which are reinforced or multiply construction. It is envisaged that used will employ the carrying handle be grasping a central handle 40 provided by the handle strap 40b and the reinforcing handle strap 40b, inserting one or more fingers through one of the first and second handle openings and a thumb through the other of the first and second handle openings.
Alternatively, users may engage the composite top wall 12/20 by inserting one or more fingers through the first handle opening and engaging one of the first or second edges E3, E4 (both of which are reinforced) of the first handle opening so as to carry the carton 90 by the central handle strap or by the portion of the composite top panel 12/20—between the first handle opening and the fold line 19—adjacent to the second edge E4.
The second handle opening comprises a first or inner side edge E1 and a second outer side edge E2. The first side edge E1 may be defined at least in part by the fold line 43 coupling the cushioning flap 42 to the handle strap 40a.
The first side edge E1 is reinforced, that is to say, the composite top wall 12/20 is of multiply construction along the first side edge E1. In the illustrated embodiment, the composite top wall 12/20 is a two-ply construction along the first side edge E1. The handle strap 40a provided by the first top wall panel 12 is reinforced by the reinforcing handle strap 40b provided by the second top wall panel 20.
The second side edge E2 is not reinforced, that is to say, the composite top wall 12/20 is of single ply construction along the second side edge E2. This has the advantage of reducing the width of the second inner top wall panel 20, thus reducing the amount of material the blank 10 requires to provide the carton 90.
The second handle opening, in particular the second aperture A2, is adapted and configured to discourage users from employing the second handle opening, independently of the first handle opening, as a means for carrying the carton 90. The second aperture A2 comprises a second edge E2 provided in part by the first top wall panel 12 and in part by the first side wall panel 14. The second edge E2 is nonlinear in shape, in particular the second edge E2 is substantially “V” shaped, converging towards the base panel 16. In this way, the second edge E2 is disposed in close proximity or alignment with the articles being packaged.
The second aperture A2 is similarly shaped and aligned with a void between two adjacent articles B1, B2 which are disposed proximate the carrying handle H. In this way, the carton 90 does not present a panel portion an internal surface of which is readily engageable by a user. In contrast to the first handle opening it is difficult for a user to insert one or more fingers through the second aperture A2 and hook said finger under the composite top panel 12/20 along the second edge E2; the second edge E2 being a single ply or a non-reinforced edge. The second edge E2 is presented to the user as a non-engaging edge; the user can intuit from the shape and configuration of the second opening the optimum or designed method of employing, engaging with, the carrying handle H.

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.
As used herein, the term “cutaway” may refer to one of the following: a recess, a notch, a slot, an opening, a outline, 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 short scores and any combination of the aforesaid options, without departing from the scope of the invention.
As used herein, the terms “hinged connection” and “fold line” each refers to all manner of lines that define hinge features of the blank or substrate of sheet material, facilitate folding portions of the blank or substrate of sheet material with respect to one another, or otherwise indicate optimal panel folding locations for the blank or substrate of sheet material. 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 one or more fold lines. 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. Atypical 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, aligned slits, a line of short scores and any combination of the aforesaid options, without departing from the scope of the invention.
As used herein, the term “severance line” may refer to all manner of lines formed in the blank or substrate of sheet material that facilitate separating portions of the blank or substrate of sheet material from one another, or otherwise that indicate optimal separation locations on the blank or substrate. As used herein, the term “severance line” may refer to one of the following: a single cut line, a single partial-depth cut line (e.g., a single half-cut line), an interrupted cut line, 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 partial-depth cuts (e.g., a line of short half cuts), and any combination of the aforementioned options.
It should be understood that hinged connections, fold lines and severance lines can each include elements that are formed in the blank or substrate of sheet material, 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 provide a fold line, to facilitate folding and facilitate breaking with more effort to provide a frangible fold line, or to facilitate breaking with little effort to provide a severance line.
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.
