ABSTRACT:
A milk carton blank formable into a liquid tight parallelepiped shaped milk carton. The milk carton blank comprises a generally rectangular shape having a plurality of panel portions formed by a gridwork of longitudinal and transverse fold lines. Cutout portions in oppositely positioned top and bottom panel portions allow the top and bottom panel portions to be folded and sealed with a relatively small number of operations. A perforated tab portion is described which may be removed from a tongue portion of the milk carton to provide a pouring spout. Additional folding lines are described which allow a portion of a top and lateral side panel of the milk carton to be thrust outwardly to facilitate pouring of liquid therefrom.
