Abstract
A carton with integral pouring spout is provided. The carton includes first and second side wall panels, first and second end wall panels hingedly connected to the first and second side wall panels, and top and bottom closure panels attached to the side wall panels to form a tubular carton having a rectangular cross-section. The integral pouring spout is formed in one of the wall panels of the carton by cooperating interior and exterior pouring spout components. The spout is adapted for cartons having a narrow width or thickness by having a split exterior spout component including an automatic supplemental side wing. The invention encompasses a single-piece flat blank for forming the carton and spout, including a removable access tab located immediately adjacent the spout to prevent unwanted opening.
