It will be appreciated that various modifications may be made within the scope of the invention. For example, the size and shape of the plates and apertures may be adjusted to accommodate articles of different sizes or shapes. The shoulder plate may be omitted. The present invention is not limited to top-engaging type cartons and the present invention may be used with other carton types such as, but not limited to, open top crates, capped or closed top crates.

It will be appreciated that directional references, such as "top", "bottom", "base", "front", "rear", "end", "side", "inner", "outer", "upper" and "lower", as used herein, do not necessarily limit the respective plates to such orientation, but merely serve to distinguish the plates from one another.

As used herein, the terms "hinge connection" and "fold line" refer to all manner of lines that define the hinge features of the blank, facilitate folding portions of the blank relative to one another, or otherwise indicate the optimal panel folding position of the blank. Any reference to "hinged connection" should not be construed as necessarily referring to only a single fold line; in practice, the hinged connection may be formed by two or more fold lines, wherein each of the two or more fold lines may be straight/linear or curved/curvilinear in shape. When the linear fold lines form a hinged connection, they may be arranged parallel to each other or slightly angled relative to each other. When the curvilinear crease lines form a hinged connection, they may intersect one another to define a shaped panel in the area enclosed by the curvilinear crease lines. A typical example of such a hinged connection may include a pair of arcuate or arcuate fold lines intersecting at two points such that they define an elliptical plate therebetween. The hinged connection may be formed by one or more linear fold lines and one or more curvilinear fold lines. Typical examples of such hinged connections may include a combination of linear fold lines and arcuate or arched fold lines that intersect at two points such that a meniscus is defined therebetween.

As used herein, the term "polyline" may refer to one of the following: score lines, embossed lines, debossed lines, perforated lines, short slits, half-cut lines, single half-cut lines, intermittent cut lines, aligned slits, scored lines, and any combination of the foregoing.

It should be appreciated that the hinged connection and the fold line may each include elements formed in the base material of the blank, including perforations, perforation lines, short slit lines, half-cut lines, single half-cut lines, intermittent cut lines, slits, scores, embossed lines, debossed lines, any combination thereof, and the like. The elements may be sized and arranged to provide a desired function. For example, the perforation lines may be sized or designed with a degree of weakness to define fold lines and/or cut lines. The perforation lines may be designed to facilitate folding and resist breaking, to facilitate folding and to facilitate breaking with greater force, or to facilitate breaking with less force.

The phrase "aligned" 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 the two overlapping panels. Those elements that are aligned with each other may be aligned with each other in the thickness direction of the overlapping plates. For example, when an aperture in a first plate is "aligned" with a second aperture in a second plate, the second plate is placed in overlapping arrangement with the first plate, an edge of the aperture may extend along at least a portion of an edge of the second aperture, and may be aligned with the second aperture in a thickness direction of the first and second plates.
