Abstract
A blank for forming a gable top carton is set forth which reduces the surface area of the carton for a given carton volume. The carton blank comprises a generally rectangular body having an upper section, a mid section, and a lower section, each of the sections being separated from each other by one or more generally horizontal score lines. The upper section of the rectangular body comprises a plurality of score lines for defining a gabled top of the resulting carton while the lower section of the rectangular body comprises a plurality of score lines for defining a folded bottom section of the resulting carton. The mid section of the rectangular body comprises a plurality of score lines for defining four sidewalls of the resulting carton. Adjacent sidewalls are separated from one another by a first score line partially extending from the upper section and a second score line partially extending from the lower section. The endpoints of the first and second score lines are separated from one another to thereby allow the resulting carton to bulge.
