A carton structure fabricated from a single blank of paperboard or similar foldable sheet material is characterized by a tubular body having hingedly connected sidewalls which are initially folded and connected in flattened relation, with panels at opposite ends of the blank overlying each other and constituting a body sidewall in which the outer wall panel has a tear tab arranged to be torn loose and hinged outwardly when the carton is set up so as to form a dispensing opening while the inner wall panel has an integral portion in which a hinged spout forming member is cut and positioned so that a portion thereof which is secured to the tear tab will be pulled into the dispensing opening and form therein a pouring spout upon outward movement of the tear tab.
