The finger tabs 50 are hingedly connected to the top panel 20 by fold lines 51 and are defined in part by a cut line or severance line. A first one of the finger tabs 50 is hingedly connected to the top panel 20 in opposition to a second one of the finger tabs 50.

Turning to the construction of the carton 90 as illustrated in Figure 2, the carton 90 can be formed by a series of sequential folding operations in a straight line machine so that the carton 90 is not required to be rotated or inverted to complete its construction. The folding process is not limited to that described below and may be altered according to particular manufacturing requirements.

A group of articles B is assembled; in the embodiment illustrated in Figure 2 six articles B are arranged in a 2 x 3 array. The top panel 20 of the blank 10 is disposed above the group of articles B to provide a top wall 20 of the carton 90. The second and third bevel panels 18, 22 are folded, with respect to the top panel 20 about fold lines 19, 21 respectively, about shoulders of the group of articles B. An outer portion of an upper end of each article B is received in a respective one of the article receiving apertures A4, A5.

The first and second side panels 16, 24 are folded, with respect to the second and third bevel panels 18, 22 to which they are hinged about fold lines 17, 23 respectively, about opposing sides of the group of articles B so as to be disposed about the opposing sides of the group of articles B to form first and second side walls 16, 24 of the carton 90.

The first and fourth corner panels 14, 26 are folded, with respect to the respective one of the first and second side panels 16, 24 about fold lines 15, 25 respectively, about the heels or lower portions of adjacently disposed articles B.

The heel tabs 42 may folded out of the plane of the first and fourth corner panels 14, 26, about fold lines 43, prior to folding the first and fourth comer panels 14, 26 the respective one of the first and second side panels 16, 24.

In some embodiments this is achieved by folding the first and second base panels 12, 28 outwardly such that the heel tabs 42 extend inwardly below the article group to engage one of the articles B, the first and second base panels 12, 28 are then folded in the opposite direction below the base of the article group.

The second base panel 28 is folded about the fold line 27 so as to be disposed adjacent to the base of the group of articles B. The first base panel 12 is then folded about the fold line 13 so as to be in at least partial overlapping relationship with the second base panel 28; in doing so each of the heel tabs 42 may be brought into engagement with a base of a respective article B.

The first and second base panels 12, 28 are secured together. Each of the male tabs M is displaced inwardly out of the plane of the second base panel 28. In so doing, each of the female tabs F is displaced inwardly creating a corresponding opening in the first base panel 12. The male tabs M are received in respective ones of the openings so as to lock the first and second base panels 12, 28 together. In this way a tubular structure is formed about the group of articles B. The assembled carton 90 is shown in Figure 2, an enlarged view of one of the article engagement structures M2 is shown in Figure 3. The tabs 30 engage a rim or chime of the article B. The tabs 30 may be displaced outwardly of the top panel 20. The tabs 30 may be displaced outwardly of the second or third bevel panel 18, 22, best illustrated in Figure 4B and Figure 6. The tabs 30 provide reinforcement in a transition region between the top panel 20 (which is disposed over the articles B) and the second or third bevel panel 18, 22 which are disposed about the shoulders of the articles B. The tabs 30 may relieve, redirect or redistribute pressure or load forces in this transition region exerted by the articles B as they engage edges of the article receiving apertures A4, A5.

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” referto 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 cutline, 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 outline, an interrupted outline, 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.
