The blank 210 comprises a first product display structure D in at least one side wall panels 212, 216 thereof, in other embodiments the blank 210 comprises first product display structure D in both side wall panels 212, 216.
The first product display structure D comprises a first tab 240 struck from, and hingedly connected, to the second side panel 216, and a second tab 242 struck from, and hingedly connected, to the second side panel 216. The first tab 240 is hinged to the second side panel 216 by a fold line 241. The fold line 241 is non-linear and is optionally arcuate in shape. In the illustrated embodiment the fold line 241 is formed from two, or more, contiguous linear sections arranged divergently with respect to each other. The second tab 242 is hinged to the second side panel 216 by a fold line 245. The fold line 245 is non-linear and is optionally arcuate in shape. In the illustrated embodiment the fold line 245 is formed from two, or more, contiguous linear sections arranged divergently with respect to each other. A part of the first tab 240 is separated from a part of the second tab 242 by a cut line 243.
The first product display structure D may comprise a first slot, cutaway or aperture A5. The first aperture A5 defines in part the first and second tabs 240, 242. The first aperture A5 defines a lower edge of each of the first and second tabs 240, 242. In other embodiments the first aperture A5 may be replaced with a cut line or severance line. The first aperture A5 or at least a portion thereof separates a portion of the first tab 240 from a portion of the second tab 242.
The first product display structure D comprises a second slot, cutaway or aperture A6. The second aperture A6 defines in part the first and second tabs 240, 242.

A cutaway or recess R is struck from the first side panel 212. The recess R is struck from a free side edge which opposes the hinged connection 213 between the first side panel 212 and the first end panel 214. The recess R is shaped so as to complementary to the first window aperture A3. Together the first window aperture A3 and the recess R form a further display structure W2 in the carrier 290.
The blank 210 comprises a second window aperture A4 struck in part from the first end panel 214 and in part from the first side panel 212 and in part from the second side panel 216. The second window aperture A4 forms another display structure W1 in the carrier 290.
The carton 290 can be formed by a series of sequential folding operations in a straight line machine so that the carton 290 may not be 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.
Turning to the construction of the carton 290 as illustrated in FIG. 2, the securing panel 220 is folded about fold line 219 to overly the second end panel 218. Glue G or other adhesive treatment is applied to an outer surface of the securing panel 220. Alternatively, glue G or other adhesive treatment may be applied to a corresponding portion of an inner surface of the second end panel 218.
The blank 210 is folded about the fold line 215 such that the first end panel 214 is disposed in overlying relationship with the second side panel 216, and the first side panel 212 is disposed in overlying relationship with the second end panel 218, the securing panel 220 and a portion of the second side panel 216. The first side panel 212 is secured to the securing panel 220.
The blank 210 is thus formed into a flat collapsed tubular structure which can be readily shipped or distributed to a convertor plant, at which the flat collapsed tubular structure may be erected into an open ended tubular structure and loaded with articles.
The flat collapsed tubular structure may be erected to form an open ended tubular structure by displacement or translation of the first side panel 212 relative to the second side panel 216 such that the first side panel 212 is spaced apart from the second side panel 216. In some embodiments this may be achieved by unfolding one of the side panels 212, 216 with respect to one of the adjacent end panels 214, 218. For example, the first end panel 214 may be unfolded about fold line 215 with respect to the second side panel 216; in doing so, the first end panel 214 is folded about fold line 213 with respect to the first side panel 212.
When the flat collapsed tubular structure is erected into the tubular form the first display structure D may be formed by folding the first and second, tabs 240, 242 with respect to the second side pane 216 to which they are hinged.
The carton 290 may be loaded with articles through one of the open ends by relative movement of the carton 290 with respect to a group of articles B. In some embodiments the lower end of the carton 290 may be closed before loading with articles B, the carton 290 being top loaded—that is to say articles B are inserted through the open upper end.
The orientation of the articles B that are disposed adjacent the openings of the display structures D, W1, W2 may be adjusted as required to a desired orientation with respect to the window whilst loaded in the carton 290 prior to closure of the top panels 222A, 224A.
A tool can be inserted through the base wall 222B/224B, passing through the respective opening of the orientation adjustment device TA disposed below the articles being adjusted.
The tool lifts or elevates the article B such that a rotation device can engage the article to rotate the article to a desired orientation.
When the article B is moved an upper portion passes through the open end of the tubular structure defined by the side and end walls 212, 214, 216, 218 and is external of the tubular structure. In this second deployed position the article B is readily accessible. The top panels 222A, 224A may be bent of folded outwardly to facilitate access to the articles B when in the elevated position. The orientation of the article B may be adjusted in the deployed position, upon reaching the desired orientation the article B may be returned to the rest position.
Once the articles B are disposed in the desired orientation they are lowered to a position of rest upon the base wall 212/220, the tool is withdrawn from the opening of the orientation adjustment device TA.
The composite top panel 222A, 224A is then assembled by folding the first top panel 222A about fold line 223A. The second top panel 224A is then folded about fold line 225A into face contacting relationship with the first top panel 222A; the second top panel 224A secured to the first top panel 222A.
In some embodiments the composite top panel 222A, 224A is assembled by application of glue G or other adhesive treatment to an outer surface of the second top panel 224A. Alternatively, glue G or other adhesive treatment may be applied to a corresponding portion of an inner surface of the first top panel 222A.
When the composite top panel 222A, 224A is assembled the first, second, third and fourth web panels 232A, 232B, 234A, 234B are folded into face to face relationship with a respective one of the side panels 212, 216 to which they are hinged. In doing so upper portions of the first and second end panels 214, 218 are deformed or bent about the inwardly with respect to the respective adjacent lower portions. In this way each of the opposing ends of the carton 290 are erected so as to have upper portions which taper inwardly towards the composite top panel 222A, 224A.
The upper portions 212U, 216U of the first and second side panels 212, 216 are folded about the respective fold lines 231, 233 to the respective adjacent lower portions 212L, 216L. In this way each of the opposing upper portions 212U, 216U of the side wall 212, 216 of the carton 290 are erected so as to taper inwardly towards the composite top panel 222A, 224A.
Once the carton 290 has been loaded with articles B the upper open end of the carton 290 is closed. The upper open end may be closed as described in the foregoing paragraphs. The lower end may be closed by assembly of the composite base panel 222B, 224B.
The composite base panel 222B, 224B is formed by folding the first base panel 222B about fold line 23B and by folding the second base panel 224B about fold line 225B into at least partial overlapping relationship with the first base panel 222B. The male components M are brought into vertical registry or alignment with the female components F.
The punch tabs M in the second base panel 224B are displaced inwardly of the carton 290 so as to press the tabs F provided in the first base panel 222B out of the plane of the first base panel 222B. The punch tabs M are received in apertures in the first base panel 222B created by said displacement of the tabs F. In this way the first and second base panels 222B, 224B are secured together.
In other embodiments alternative securing means may be employed to secure the first and second base panels 222B, 224B for example, but not limited to, mechanical locking devices such as staples, glue or other adhesive treatment.
FIG. 7 illustrates an assembled carton 290 forming a package with a plurality of articles B.
In the erected condition, the web panels 232A, 232B, 234A, 234B are disposed in an overlying or face to face relationship with the respective one of the first and second side panels 212, 216.
When the carton is erected the upper portions 212U, 216U of the side panels 212, 216, are folded with respect to the lower portions 212L, 216L such that the upper portions 212U, 216U taper inwardly towards the composite top panel 222A/224A. Upper portions of the first and second end panels 214, 218 converge inwardly towards the composite top panel 222A/224A.
The first tab 240 and the second tab 242 of the first product display structure D are disposed internally of the carton 290 and form a partition structure 240/242 which at least partially separates an article B disposed adjacent the first product display structure D from its adjacent neighbours. The first tab 240 and the second tab 242 of the first product display structure D form a frame about the article being displayed in the display window of the first product display structure D.
The first tab 240 and the second tab 242 in the erected state are non-planar; that is to say they are not flat surfaces. In the illustrated embodiment, the first tab 240 and the second tab 242 may each comprise two or more planar portions folded with respect to each other. In other embodiments, the first tab 240 and the second tab 242 form into plane curves; that is to say, they comprise a curved surface.
The present disclosure provides a carton 90; 190; 290 for packaging articles B; the carton 90; 190; 290 may have at least one display window for presentation of an article B therein. The carton 90; 190; 290 comprises a plurality of panels forming walls of a tubular structure including a top wall, a first side wall, a base wall, and a second side wall, optionally hingedly connected to each other in a linear series.
The cartons 90; 190; 290 may comprise at least one display window W, D, W1, W2 defined in or by an end or side wall.
The display window W, W1, W2 may expose to view a pair of endmost articles B, particularly a label or other indicia printed or otherwise displayed on a lower or main body portion of the articles B.
The articles B comprise a main body and a neck portion disposed above the main body; the neck portion comprises a smaller dimension or diameter than the main body. A shoulder region provides a transition between the main body and the neck portion. The display window is arranged such that a portion of the side or end wall obscures from view at least the neck of portion thereof. In some embodiments, the shoulder region or an upper portion of the main body or both may be obscured from view. A lower portion, heel or base of the article B may be obscured from view.
The second display window DW1, DW2 is defined in part by free side edge portions of each of the first and second side walls 214 a, 218 a.
In this way branding or other indicia provided upon the articles B may be displayed through the display window W, D, W1, W2. The articles B may be arranged in a desired orientation. The displaceable flaps 240, 242 may bear against an article B so as to prevent or inhibit rotation of the article B away from the desired orientation.
The carton 90; 190; 290 comprises an orientation adjustment device for enabling the orientation of an article B which is at least partially exposed to view through the display window. The orientation adjustment device comprises a first cutaway in the form of an aperture or opening in a first panel of the carton. The first panel may be a base panel. The first cutaway is configured to allow access to a first end, optionally a base portion, of an article B. The first cutaway is configured to prevent the first end of the article B passing therethrough.
The top wall of the carton may be shorter than the base wall in a transverse direction perpendicular to the tubular axis of the tubular structure formed by the plurality of main panels.
The present disclosure further provides a method of packaging articles or a method of assembling a carton, in which the method enables the position of one or more articles, or the orientation of said one or more articles, or both the position and orientation of said one or more articles, to be adjusted and optionally secured or held whilst within the carton.
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.
