Abstract
A gable-top carton and a corresponding carton blank are set forth. The upstanding fin of the carton comprises a centrally disposed depressed region that facilitates stacking of the cartons on top of one another in a manner that results in a more even load distribution on the fins of the lower cartons than obtained when stacking conventional gable-top cartons. A further advantage is realized in the corresponding carton blanks in that the corresponding blanks may be disposed in a top-to-top manner along the width of a web of material whereby savings in material and production costs results.
