in the illustrated embodiments.
[0068] It will be recognised that as used herein, directional references such as "top",
"bottom", "front", "back", "end", "side", "inner", "outer", "upper" and "lower" do
not limit the respective panels to such orientation, but merely serve to distinguish
these panels from one another.
[0069] As used herein, the terms "hinged connection" and "fold line" refers 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 scored line, an embossed line, or a debossed
line. 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 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.
[0070] 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.
[0071] 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.
