As used herein, the word “exemplary” is used expansively to refer to embodiments that serve as illustrations, specimens, models, or patterns. Indeed, it will be understood that the packages, blanks and cartons described herein may be embodied in various and alternative forms. The Figures are not necessarily to scale and some features may be exaggerated or minimised to show details of particular components. Well-known components, materials or methods are not necessarily described in great detail in order to avoid obscuring the present disclosure. Any specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the invention.
- Referring to
FIGS. 1 and 1B , there is shown a plan view of a blank 10 capable of forming a carton orcarrier 90 as shown inFIGS. 2 and 3 , whichcarton 90 can accept an input of primary products such as, but not limited to, bottles or cans, hereinafter referred to as “articles”. - In the embodiments detailed herein, the terms “carton” and “carrier” refer, for the non-limiting purpose of illustrating the various features of the invention, to a container for engaging, carrying, and/or dispensing articles, such as product containers. It is contemplated that the teachings of the invention can be applied to various product containers, which may or may not be tapered and/or cylindrical. Exemplary containers include bottles (for example metallic, glass or plastics bottles), cans (for example aluminium cans), tins, pouches, packets and the like.
- The blank 10 is formed from a sheet of suitable substrate. It is to be understood that, as used herein, the term “suitable substrate” includes all manner of foldable sheet material such as paperboard, corrugated board, cardboard, plastic, combinations thereof, and the like. It should be recognized that one or other numbers of blanks may be employed, where suitable, for example, to provide the carrier structure described in more detail below.
- In the embodiment illustrated in
FIG. 1 , the blank 10 is configured to form a carton orcarrier 90 for packaging an exemplary arrangement of exemplary articles. In the illustrated embodiment the arrangement is an m×n matrix or array, having three rows (m=3) and four columns (n=4); in the illustrated embodiment three rows of four articles are provided, and the articles are 405 ml cans; the cans may be formed from a suitable material such as, but not limited to, Aluminum. The blank 10 can be alternatively configured to form acarrier 90 for packaging other types, number and size of article and/or for packaging articles in a different arrangement or configuration. - The blank 10 comprises a plurality of
primary panels side wall panel 12 is hinged to a second primary panel 14 (also referred to herein as a bottom panel 14) by a fold line (e.g., a core line or crease line) 13.

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 recognized 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. A fold line is typically a score line, a crease line, an embossed line, or a debossed line. However, a fold line may be a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cut line, an interrupted cut line, slits, scores, any combination thereof, and the like. Any reference to “hinged connection” or “fold line” should not be construed as necessarily referring to a single fold line only; indeed it is envisaged that a hinged connection can be formed from any one or more of the following: a short slit, a frangible line or a fold line without departing from the scope of the invention.
- As used herein, the term “severance line” refers to all manner of lines that facilitate separating portions of the substrate from one another, or that indicate optimal separation locations. Severance lines may be frangible or otherwise weakened lines, tear lines, cut lines, or slits.
- It should be understood that hinged connection, severance lines 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 cut line, an interrupted cut line, 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.
