  • the second outermost end flap 22B has a second hinged securing flap portion 32B secured to the outside surface of the outer end flap 24B.
  • At least one of the inner and outer end flaps 28B, 26B has a handle H disposed between the outermost end flaps 26B, 22B such that it is exposed to view from the outside of the carrier 90.
  • dispenser may be employed in cartons of alternative design such as, but not limited to, wraparound style cartons, basket carries and top gripping clips.
  • directional references such as “top”, “base”, “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.
  • hinged connection 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 one or more of the following: a short slit, a frangible line or a fold line, without departing from the scope of the invention. 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 term “cutaway” may refer to one of the following: a recess, a notch, a slot, an opening, a cutline, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, an interrupted cut line, aligned slits, a line of short scores and any combination of the aforesaid options, without departing from the scope of the invention.
  • hinged connection and “fold line” each refers to all manner of lines that define hinge features of the blank or substrate of sheet material, facilitate folding portions of the blank or substrate of sheet material with respect to one another, or otherwise indicate optimal panel folding locations for the blank or substrate of sheet material. 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 one or more fold lines.
  • 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 cut line, aligned slits, a line of short scores and any combination of the aforesaid options, without departing from the scope of the invention.
  • the term “severance line” may refer to all manner of lines formed in the blank or substrate of sheet material that facilitate separating portions of the blank or substrate of sheet material from one another, or otherwise that indicate optimal separation locations on the blank or substrate.
  • the term “severance line” may refer to one of the following: a single cut line, a single partial-depth cut line (e.g., a single half-cut line), an interrupted cut line, a score line, an interrupted score line, a line of perforations, a line of short cuts, a line of short slits, a line of short partial-depth cuts (e.g., a line of short half cuts), and any combination of the aforementioned options.

  • 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 provide a fold line, to facilitate folding and facilitate breaking with more effort to provide a frangible fold line, or to facilitate breaking with little effort to provide a severance line.
