• At least one of the pair of side end flaps 222A/224A, 222B/224A, 226A/228A, 226B/228B comprises a corner panel 226A, 226B 228A, 228B with an upper edge.
• the top end flap 214A/214B, 216A/216B is provided along at least one of its side edges with a recessed edge R.
• the plurality of end closing flaps are secured together to form the end closure structure in which the upper edge of the corner panel 226A, 226B 228A, 228B intersects, meets or crosses the recessed edge R of the top end flap 214A/214B, 216A/216B.
• the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape, a greater or lesser number of articles and/or arranged in different array configurations.
• 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/li near or curved/curvi linear 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.
• curvilinear fold lines 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.
• 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.
• 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, embossed lines, debossed lines, any combination thereof, and the like.
• the elements can be dimensioned and arranged to provide the desired functionality.
• 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.
• in registry with 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.
