TETRAHEDRAL TOP CARTON
The present invention is tetrahedral top carton (20) and a blank (100) therefor. The carton (20) has at least a nine percent material savings over a traditional gable top carton containing an equal volume of product. The carton (20) has a tetrahedral top structure (22) formed from four top panels (34, 36, 38, 40) intersecting and sealed adjacently. The carton (20) may have a fitment (24) thereon for accessing the contents. The fitment (24) may be placed on the pinnacle of the tetrahedral top structure (22) or on a single top panel (34, 36, 38 or 40). The carton (20) may have outward folded fins (62, 64, 66 and 68) projecting from the intersection of the top panels (34, 36 38, 40), or the fins may be folded inward to create diagnonal creases/edges (52, 54, 56, 58) in the intersection between adjacent top panels (34, 36, 38, 40). The carton blank (100) may also have a plurality of bottom fins (292, 294, 296, 298, 300, 302, 304) to create an overfolded bottom for reverse filling on a form, fill and seal packaging machine.
