The fold line 33 b is also referred to herein as first fold line 33 b.
The severance line 70 extends across or through the fold line 35 b between the top end closure panel 32 b and the gusset panel 34 b, this fold line is also referred to herein as third fold line 35 b.
The severance line 70 extends across or through the fold line 37 b between anchoring panel 36 b and the gusset panel 34 b, this fold line is also referred to herein as fifth fold line 37 b.
The severance line 70 can be considered to intersect or terminate each of the first, second, third, fourth and fifth fold lines 33 b, 19, 35 b, 39 b, 37 b.
The severance line 70 in the illustrated embodiment is non-linear and may be curvilinear. In other embodiments the severance line 70 may be defined by two or more linear sections divergently arranged with respect to each other. In still other embodiments the severance line 70 may be linear. In embodiments in which the severance line 70 is linear the severance line 70 may be divergently arranged with respect to the first and/or fourth fold lines 33 b, 39 b. The severance line 70 may be divergently arranged with respect to second fold line 19 and may be obliquely oriented thereto.
The severance line 70 extends between the first fold line 33 b and fourth fold line 39 b.
The severance line 70 bypasses a notional intersection or vertex between a notional extension of the first fold line 33 b and the second fold line 19 such that the notional intersection is located on one side of the severance line 70. The notional intersection is located on a first side of the severance line 70 and anchor and gusset panels 36 b, 34 b are located on a second, opposing, side of the severance line 70. The notional intersection may be spaced apart from the anchor and gusset panels 36 b, 34 b.
The third fold line 39 b may intersect or pass through the notional vertex. Notional extensions of the fourth and fifth fold lines 39 b, 37 b may intersect or pass through the notional vertex.
The fifth fold line 37 b may be interrupted by a “U” shaped cut line 43 b to define a tab portion struck from material which would otherwise form the gusset panel 34 b. The tab portion is integral with the anchor panel 36 b.
The severance line 70 intersects with the third fold line 35 b at a first intersection. The first intersection is disposed at a position closer to the gusset panel 34 b than the notional intersection of the first fold line 33 b and second fold line 19.
In an alternative embodiment of the corner folding arrangement the severance line 70 may comprise an extension, the extension extends the severance line 70 further into the top panel 18. Whereas in the embodiment of FIG. 1 the severance line 70 terminates in the top panel 18 at a location substantially lying upon a notional extension of the fourth fold line 39 b in the alternative embodiment the extension extends the severance line 70 beyond the notional extension of fourth fold line 39 b. In further alternative embodiments the severance line 70 may terminate at other locations, and may terminate at the end edge of the top panel 18 defined by the first fold line 33 b. It some embodiments the severance line 70 may extend into the second side panel 20.
Folding of each upper tab is achieved during the erection of the carton. To form a top end closure structure out of each upper tab, the anchoring panel 26 a, 26 b, 36 a, 36 b is folded about 180 degrees to bring it into a face-contacting relationship with the inside surface of the adjacent side panel 16, 20. The anchoring panel 26 a, 26 b, 36 a, 36 b is held in the folded position by being pressed by one of the packaged articles B against the adjacent side panel 16, 20. The folding of the anchoring panel 26 a, 26 b, 36 a, 36 b causes the gusset panel 28 a, 28 b, 34 a, 34 b to be folded outwardly about the fold line 27 a, 27 b, 37 a, 37 b so that the gusset panel 28 a, 28 b, 34 a, 34 b extends outwardly from the fold line 27 a, 27 b, 37 a, 37 b along the side wall of the one packaged article B. At the same time, the web panel 30 a, 30 b, 32 a, 32 b is caused to fold downwardly along the fold line 31 a, 31 b, 33 a, 33 b and is thereby brought to a folded position where it extends between the fold line 31 a, 31 b, 33 a, 33 b and the outer edge of the gusset panel 28 a, 28 b, 34 a, 34 b. The top end closure structure thus completed is illustrated in FIG. 2 wherein the structure is shown as tightly engaging the top of the one article B.
Each lower projection serves to provide sufficient material in which the adjacent heel engagement structure N and its associated opening is defined. More particularly, the heel engagement structure N adjacent to each lower projection is positioned such that sufficient material surrounds the heel engagement structure N even when the opening extends into that lower projection. During the erection and packaging of articles B, the blank 10 is manipulated so that each opening receives the bottom of a respective article B to retain said article B within the carton 90. The heel tabs 40 may also be folded internally of the carton 90 to engage a portion of an article to assist in retaining the articles B. The heel tabs 40 may be received in a recess in the lower (or upper) end of the article B.
Turning to the construction of the carton 90 as illustrated in FIG. 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 FIG. 2 six articles B are arranged in a 3×2 array. The top panel 18 of the blank 10 is disposed above the group of articles B to provide a top wall 18 of the carton 90.
The first and second side walls 16, 22 are folded, with respect to the top panel 18 about fold lines 17, 19 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.
The anchor portions 26 a, 26 b, 36 a, 36 may be folded into face contacting relationship with the respective one of the first and second side panels 16, 20 substantially simultaneously with folding the first and second side walls 16, 20 with respect to the top panel 18, to form the top end closure structures described above.
Alternatively, the top engaging structures may be formed subsequent to erection of the carton 90 into a tubular form. The anchor portions 26 a, 26 b, 36 a, 36 may be tucked between the respective one of the first and second side panels 16, 20 to which they are hingedly connected and an adjacently disposed article B.
The first and second corner panels 14, 22 are folded, with respect to the respective one of the first and second side walls 16, 20 about fold lines 15, 21 respectively, about the heels or lower portions of adjacently disposed articles B.
The heel tabs 40 may folded out of the plane of the first and second corner panels 14, 22, about fold line 41, prior to folding the first and second corner panels 14, 22 the respective one of the first and second side walls 16, 20.
The second base panel 24 is folded about the fold line 23 so as to be disposed adjacent 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 24; in doing so each of the heel tabs 40 may be brought into engagement with a base of a respective article B.
The first and second base panels 12, 24 are secured together. Each of the male tabs M is displaced inwardly out of the plane of the first base panel 12. In so doing, each of the female tabs F is displaced inwardly creating a corresponding opening in the second base panel 24. The male tabs M are received in respective ones of the openings so as to lock the first and second base panels 12, 24 together. In this way a tubular structure is formed about the group of articles B.
The assembled carton 90, or at least a portion thereof, is shown in FIG. 2 . It can be observed that the deformable member has been displaced relative to the adjacent regions of the carton 90. The deformable member may be bent or bowed outwardly at it centre so as to appear convex when viewed from an external vantage point. Region of the deformable member surrounding the first separation line 45 may deform such that the first separation line 45 opens up to create an aperture in therein. The pair of second separation lines 49 a, 49 b and the second expansion slit 47 may open up similarly so as to relieve stress in blank 10 and deformable member.
The major tab 42 and minor tabs 44 a, 44 b may provide some degree of protection to the portion of the article B received in the opening.
The article-retaining devices may be advantageous in that the allow creation of openings in the blank 10 or carton 90 without creating pieces of scrap material (paper board) which need to be separated from the blank 10. In high-speed die-cutting and blanking processes such scrap pieces may tend to hang or snag on the blank 10 or they may be scattered around the die cutting station. Rogue scrap pieces may find their way into subsequent packaging machinery where they may interfere with the assembly process causing jams or downtime. They may cause damage to the machinery or packages.

The cut lines 151 a, 151 b are arranged perpendicular to the fold line 115. In this way an uninterrupted connection between the first corner panel 114 and the first side panel 116 is provided on opposing sides of the deformable member.
The heel tab 140 comprises a pair of crease or fold lines 153 a, 153 b. The crease lines 153 a, 153 b may be defined in part by a cut line 153 a, 153 b. The crease lines 153 a, 153 b are divergently arranged with respect to each other and allow or facilitate folding of corner or marginal edge regions of the heel tab 140 with respect to a central or intermediate region.
The heel tab 140, or at least a portion thereof, has a width equal to that of the major tab 142 or portion thereof. The heel tab 140 comprises a pair of opposing side edges defined by a pair of cut lines extending between the fold line 113 and the first separation line 143. Each of the pair of cut lines may be perpendicular to the first separation line 143 or end portion thereof. The pair of cut lines may comprise linear portions which are divergently arranged with respect to each other. The linear portions may diverge towards the first separation line 143. The fold line 141 may extend between terminal ends of the pair of cut lines. A portion of each of the pair of cut lines may be collinear with the fold line 113 and may be contiguous with the fold line 113 and fold line 141. In this way the fold line 141 is separated from the fold line 113 by each of the pair of cut lines.

It will be appreciated that the article-retaining device N comprises a unitary deformable member formed from at least part of the second panel 316 and/or third panel 314 when present. The unitary deformable member extends continuously across the opening such that the unitary deformable member bridges between opposed side edges of the opening. Additionally, the unitary deformable member continuously extend to one of upper and lower end edges of the opening.
The deformable member can be considered to be defined or circumscribed by a separation line 343 and a weakened line. The weakened line comprises the pair of second separation lines 349 a, 349 b, the first joint J1, the second joint J2, the sixth joint J5 and the seventh joint J6. The separation line 343 disconnects the deformation member from the first panel 312. The weakened line connects the deformable member to the second panel 316 and/or third panel 314 (when present) via three or more connecting nicks provided by the joints J1, J2, J5, J6. In this way the deformable member may be displaceable from the plane of the second panel 316 and/or third panel 314, when present.
In the embodiment of FIG. 8 the heel tab is omitted. The first separation line 343 defines at least in part a projection or lobe 346 extending from the first panel 312. The lobe 346 is integral with the first panel 312. The lobe 346, when the article-retaining device is in use, may extend over or under an end of an article B being engaged. The lobe 346 may provide a protective cover to a portion of the article B protruding through the opening of the article-retaining device.

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 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 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 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 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.
