ABSTRACT:
A gabletop carton for storing liquid, viscous and solid material includes a carton material stock formed of paperboard having at least an inner facing sheet, an outer facing sheet and a fluted medium fixedly positioned between the inner and outer facing sheets. The fluted medium is positioned between the inner and outer facing sheets so as to define substantially flat, inner and outer facing sheet surfaces. The carton material stock is formed to define a bottom wall, a plurality of upstanding side walls and a top portion having a gable configuration. The bottom wall is contiguous with the upstanding side walls which are defined by a plurality of side wall creases in the material stock. The bottom wall is defined by a plurality of bottom wall creases in the material stock that are generally transverse to the side wall creases. The top portion is formed by a plurality of top wall creases generally parallel to the bottom wall creases, and a plurality of angled gable creases formed in at least some of the side walls so as to form inner and outer gable walls. The fluted medium has a flute density of about 250 flutes per linear foot and is formed to define a plurality of columns that are oriented generally transverse to the side wall creases. The inner and outer facing sheets can include a polymeric material applied thereto.
