The engaging flaps are defined in part by a free edge which includes a second or non-engaging segment 273b, 277b (defined by the second cut line portions 273b, 277b) forming a truncation or non-protrusion. The second segment 273b, 277b includes a part of the free edge which is disposed closest to a carton side panel 216, 224, in an erected, or folded, form of the carton; this is best illustrated in FIG. 7 in which the dot-dash lines indicate the folded or erected position of the tabs 270, 272. The dash lines indicate the positions of the articles B relative to the first base panel 212. The engaging flaps in the erected condition are folded inwardly through an angle greater than 90 degrees and toward the side panel 216.

The second segment 273b, 277b may be a straight segment, a re-entrant segment, a concave segment, a concavely curved segment or a concavely angled segment.

The free edge of the tabs 270, 272 comprise at least one engaging segment 273c, 277a, 277c. The engaging segment 273b, 277b (defined by the second and third cut line portions 273c, 277a, 277c) forms a protrusion, prominence or salient region.

The cutaway or notch A2 is located along a portion of the free edge of the tabs 270, 272 when the tab 270, 272 is in an unfolded condition. The second or truncated segment 273b, 277b is disposed adjacent to the cutaway or notch A2.

The second or truncated segment 277b of the second intermediate article engagement structures T9, T12 may be located such that it defines a part of the cutaway or notch A2 when the tab 272 is in the initial position.

The second or truncated segment 273b of the second end article engagement structures T1, T2, T7, T8 may be located such that it extends from the cutaway or notch A2 when the tab 270 is in the initial position.

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. The illustrated embodiments show cartons or blanks for forming an article carrier of the wraparound style; in other embodiments, the article carrier may take an alternative format or styles and may employ one or more of the features of the present disclosure.

It will be recognised 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.
