The material of the paperboard substrate may be selected from any conventional paperboard, for example, ranging in weight upwardly from about 10 pt., preferably from about 16 pt. to about 28 pt. (0.028″/˜0.7 mm). An example of such a substrate is an 18 point (pt.) SBS board (solid bleached sulfate paperboard coated on one side, trade name PrintKote®) or CNK® board (Coated Natural Kraft®—an unbleached kraft paperboard having a clay coating on one side, trade name CarrierKote™) manufactured by WestRock® Company. The paperboard substrate may be a bleached or unbleached board. The board may be coated on at least one side, optionally the side opposite the lamination, with a conventional coating selected for compatibility with the printing method and board composition.
The blanks 10; 110 may include a tear resistant layer laminated to the paperboard layer. It optionally includes an adhesive layer between the paperboard substrate and the tear resistant layer. The tear resistant layer may be disposed over the uncoated side of the paperboard substrate and may be formed of polymeric material and secured to the substrate. The tear resistant layer imparts toughness to the laminate structure. Suitable tear resistant materials may include, but not be limited to, tear resistant laminated sheet material, e.g., NATRALOCK®, which may include a layer of an n-axially oriented film, e.g. MYLAR®, which is a bi-axially oriented polyester, oriented nylon, cross-laminated polyolefin or high density polyolefin. The orientation and cross-laminated structure of these materials contribute to the tear resistant characteristic. Also, tear resistance may be attributed to the chemical nature of the tear resistant material such as extruded metallocene-catalyzed polyethylene (mPE).
Alternatively, the tear resistant layer may be a layer of linear low-density polyethylene (LLDPE). In embodiments where linear low-density polyethylene (LLDPE) or mPE is used, it is not necessary to incorporate an adhesive layer. Other suitable materials having a high level of tear resistance may also be used.
The adhesive layer may be formed of polyolefin material such as a low-density polyethylene (LDPE). The adhesive layer may be placed between the substrate and the tear resistant layer to secure the tear resistant layer to the substrate.

A bridging structure couples the end strap 26A/22A/12/22B/26B, 30A/24A/16/24B/30B; 126N-122A/112/122B/126B, 130A/124A/116/124B/130B to the main panel 14; 114.
The bridging structure comprises a bridging panel 6, 8; 106, 108 hinged to the end strap 26A/22A/12/22B/26B, 30A/24A/16/24B/30B; 126A/122A/112/122B/126B, 130A/124A/116/124B/-130 by a first hinged connection in the form of a fold line 19; 119.
The bridging panel 6, 8; 106, 108 is hinged to the main panel 14; 114 by a second hinged connection in the form of a fold line 4, 5; 160, 164. The second hinged connection may be nonlinear. The second hinged connection may be shorter than the first hinged connection. The bridging panel 6, 8; 106, 108 may be tapered in shape so as to reduce in width towards the centre of the main panel 14; 114.
The bridging panel 6, 8; 106, 108 may be hinged to a medial portion of the main panel 14; 114.
The bridging panel 6, 8 may be hinged to at least one keel panel 14C, 14D forming a keel structure 14C/14D disposed between a first row of article retention structures RT1, RT2 or article top engaging devices 70A, 70B, 72A, 72B and a second row of article retention structures RT1, RT2 or article top engaging devices 70A, 70B, 72A, 72B.
The bridging panel 6, 8 may be hinged to each of a pair of keel panels 14C, 14D forming a keel structure 14C/14D disposed between a first row of article retention structures RT1, RT2 or article top engaging devices 70A, 70B, 72A, 72B and a second row of article retention structures RT1, RT2 or article top engaging devices 70A, 70B, 72A, 72B.
In a package the bridging panel 6, 8 may be disposed in a void between a first, endmost, article B1, B2 provided in a first row of article retention structures RT1, RT2 or article top engaging devices 70A, 70B, 72A, 72B and a second, endmost article B1, B2 provided in a second row of article retention structures RT1, RT2 or article top engaging devices 70A, 70B, 72A, 72B. The second, endmost article B1, B2 is disposed adjacent to first, endmost, article B1, B2.
The bridging panel 6, 8 is inclined with respect to the main panel 14; 114. The bridging panel 6, 8 is obliquely oriented with respect to the main panel 14; 114 and the end strap 26A/22A/12/22B/26B, 30A/24A/16/24B/30B; 126A/122A/112/122B/126B, 130A/124A/116/124B/-130.
A fugitive glue may be employed to secure the side panels 18, 20; 118, 120 to the articles B1, B2. An example of a specific glue is Swift®melt 7044 manufactured by HB Fuller. Use of a fugitive glue is optional, an advantage of a fugitive glue is its tendency to remain attached to the carrier 90 when the articles B1, B2 are disengaged from the carrier 90 (this may be more desirable than having the glue remain attached to the articles B1, B2). In alternative embodiments other adhesives maybe employed such as, but not limited to, hot-melt glue.
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 inner and/or outer shoulder panels may be omitted entirely or may be included in any desired combination. The present invention is not limited to cartons of the top-engaging type, the invention may be employed with other carton styles such as, but not limited to, open top crates, lidded or closed top crates and fully enclosed cartons.
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, embossed lines, debossed lines, 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.
