ABSTRACT:
A gable top type paperboard carton for juices and other pourable product which may attack the integrity of seals is formed with a pour spout fitment attached to one of the two sloping roof panels. The carton is formed so as to exhibit a rectangular cross section transverse to its longitudinal (vertical) axis, to thereby yield a gable top whose sloping roof panels extend upwardly from the narrower carton side walls. In use, the consumer grasps the two widest side walls of the carton by the thumb and one or more other fingers. This is in distinction to grasping the narrower carton sides, which would entail a wider finger grasp or span. The carton includes a V pocket forming panel in a first gusset, the V pocket receiving a V forming point or wedge on the second gusset. A similar V forming pocket and V point may be located on opposite bottom closure panels. Either V forming pocket may be of paperboard or of barrier film. This construction overcomes the problem of abutting tips of opposite gussets which arises when the gussets are necessarily moved towards each other to form longer sloping roof panels, so as to accept a larger diameter pour spout.
