Reducible volume containers

A carton blank for forming a reducible volume container comprising the following:

• a laminated blank body having a top and a bottom;
• a plurality of bottom creases formed in the bottom of the blank body to define bottom flaps that are adapted to be folded and sealed to form a bottom surface of a finished carton, including a horizontal bottom crease extending substantially between the sides of the carton blank, defining first, second, third, and fourth bottom flaps between the horizontal bottom crease and the bottom of the carton blank, with the bottom flaps being separated from one another by lower portions of the vertical creases;
• a plurality of top creases formed in the top of the blank body, the top creases defining top flaps that are adapted to be folded and sealed to form a top surface of a finished carton, including a horizontal top crease extending substantially between the sides of the carton blank, defining first, second, third, and fourth top flaps between the horizontal top crease and the top of the carton blank, with the top flaps being separated from one another by upper portions of the vertical creases;
• a plurality of substantially equidistantly spaced vertical creases extending from the top of the carton blank to the bottom of the carton blank, separating the carton blank into first, second, third, fourth, and fifth vertical panels;
• a monoaxially oriented material disposed on an inner surface of the carton blank;
• and
• a plurality of tear strips disposed between the horizontal top crease and the horizontal bottom crease, with each of the tear strips being defined by a pair of generally parallel frangible tear lines;
• wherein each tear line includes a linear cut formed in an exterior surface of the carton blank, with the linear cut disposed parallel to the orientation of the monoaxially oriented material.
