[0192] Turning now to FIG. 12 there is shown an apparatus 1000 for applying a carrier 90, such as but not limited to those described herein, to a pair of articles B. The apparatus 1000 and method will be described by way of example with reference to the carrier 90 shown in FIG. 1C, however the apparatus 1000 and method is not limited to application of the carrier 90 of FIG. 1C.

[0193] The apparatus 1000 comprises an applicator 1010 including an applicator plate 1012. The applicator 1010 may be adapted to pick up a carrier 90 from a hopper or magazine (not shown). The applicator may comprise a vacuum system (not shown) including a vacuum cup for engaging and removing the carrier 90 from the hopper. In other embodiments, alternative gripping devices may be employed as known in the art. In still other embodiments, the carrier 90 may be picked up, aligned and placed upon the group of articles B by a separate apparatus (not shown) before entering a working region of the apparatus 1000.

[0194] FIGS. 13 and 15 illustrate the applicator plate 1012 from below, the applicator plate 1012 comprises at least one orifice O.sub.R1, O.sub.R2, the illustrated embodiment comprises a pair of orifices O.sub.R1, O.sub.R2. The orifices O.sub.R1, O.sub.R2 define an open end of a bore in the applicator plate 1012. The bore may be blind, partially blind or open. In the illustrated embodiment, the bore is partially blind. A bushing 1020 is disposed in the bore and comprises an annular side wall 1022 and provides a saddle 1030, best shown in FIG. 14, at a lower end thereof. The saddle 1030 provides a pair of opposed abutment surfaces 1024A, 1024B. A U shaped recess is provided between the pair of opposed abutment surfaces 1024A, 1024B. In alternative embodiments, it will be appreciated that a pair of opposed abutment surfaces may be provided by alternative structures mounted to or integral with the applicator plate 1012. The pair of opposed abutment surfaces are spaced apart from each other sufficient that a portion of an article B can be received therebetween. In the illustrated embodiment, the portion of the article B received is an end closure C of a bottle.

[0195] The bushing 1020 is oriented with respect to the carrier 90 such that the pair of opposed abutment surfaces 1024A, 1024B make contact and apply force or pressure to the second panel 514 at contact points PP, as shown in FIG. 1C. The carrier 90 comprises a pair of contact points PP on opposing sides of each article retention structure RT. Each saddle 1030 transversely straddles one of the article retention structures RT. The U shaped recesses of the saddle 1030 extend in a longitudinal direction, and the U shaped recess of one saddle 1030 is collinear with the U shaped recess of the other saddle 1030.

[0196] One of the pair of opposed abutment surfaces 1024A, 1024B is disposed at a different elevation to the other one of the pair of opposed abutment surfaces 1024A, 1024B, best illustrated in FIG. 16, in which the applicator plate 1012 has been omitted for illustrative purposes. In this way the applicator 1010 applies force or pressure unevenly or asynchronously to the side or longitudinal edges of the carrier 90. The applicator 1010 unevenly or unequally displaces the opposing sides of the carrier 90 from a planar condition. A first abutment surface 1024A is disposed at a first elevation and is configured to make contact with a contact point PP along a first side of the carrier 90 before a second abutment surface 1024B, which is disposed at a higher elevation, makes contact with a second contact point PP along a second side of the carrier 90.

[0197] FIG. 16B illustrates an alternative bushing 1220, having an annular wall 1222, which is substantially similar to the bushing of FIGS. 13 to 16 albeit a pair of opposed abutment surfaces 1024A, 1024B are disposed at the same elevation. In this way the bushing 1220 applies force or pressure evenly or synchronously to the side or longitudinal edges of the blank 10 (or carrier 90). The bushing 1220 evenly or equally displaces the opposing sides of the blank 10 from a planar condition. The first abutment surface 1024A makes contact with a contact point along a first side of the blank 10 and a second abutment surface 1024B makes contact with a second contact point along a second side of the blank 10 at substantially the same time.

[0198] The annular wall 1022 of the bushing 1020 may be inclined downwardly, as viewed in FIG. 14, (albeit upwardly in normal use as shown in FIG. 16) from inside to outside, in the region of the U shaped recess between the pair of opposed abutment surfaces 1024A, 1024B.

[0199] The U shaped recesses in the saddles 1030 allow, or provide a void, into which the engaging tabs 40, 42, 44 may be displaced when the carrier 90 is applied to the articles B. In this way the bushing 1020 does not interfere or inhibit movement of the engaging tabs 40, 42, 44.

[0200] The carrier 90, or at least portions thereof surrounding the article retention structures R may adopt an inverted U shaped form in response to engagement by the saddles 1030 whilst being applied to the articles B.

[0201] Referring now to FIG. 17 there is shown an alternative embodiment of the applicator 1110 having an applicator plate 1112 configured to apply three carriers 90 (outline positions of the carriers 90 are indicated by dashed lines in FIG. 17) simultaneously to three groups or pairs of articles B. The applicator plate 1112 comprises six bushings 1120 mounted thereto arranged in a 23 matrix or array. In other embodiments, it will be appreciated that other configurations may be employed, to apply a different number of carriers or package a different number of articles as desired.

[0202] In some embodiments, bushings 1020; 1120 may be retro fitted to an existing applicator plate to adapt an existing packaging machine to apply paperboard carriers to articles B.

A first one of the series of engaging tabs 40, 42, 44; 140, 142, 144; 240, 242, 244; 440, 442, 444; 540, 542, 544; 640, 642, 644; 740, 742, 744 is hinged to the primary panel 12, 14, 16; 112; 212, 214; 412, 414, 416; 512, 514, 516; 612, 614, 616; 712, 714 by a first fold line 41, a second one of the series of engaging tabs 40, 42, 44; 140, 142, 144; 240, 242, 244 is hinged to the primary panel 12, 14, 16; 112; 212, 214; 412, 414, 416; 512, 514, 516; 612, 614, 616; 712, 714 by a second fold line 43. The first and second fold lines 41, 43 define therebetween an obtuse angle which optionally may be between 115 and 135 and further optionally may be about 125. The first fold line 41 optionally defines an angle of about 20 with respect to a first notional line x-x while the second fold line 43 optionally defines an angle of about 15 with respect to a second notional line y-y. First notional line x-x is parallel to the longitudinal axis of the primary panel 12, 14, 16; 112; 212, 214; 412, 414, 416; 512, 514, 516; 612, 614, 616; 712, 714, and second notional line y-y is perpendicular to first notional line x-x.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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 cutline, an interrupted cutline, 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 or a severance line or both. 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.

[0224] 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.
