摘要： A bag device comprising side walls and opposite ends with at least one end including a closure means closing a charging and discharge opening. The closure means includes a pair of end flaps which are folded inwardly towards the opening. A pair of side flaps extend inwardly over the end flaps and the opening. A passageway extends between one of the end flaps and the side flaps which is in communication with the opening to permit insertion therein of a charging spout. A flexible sleeve is secured to the said one end flap so that when the side flaps and sleeve are longitudinally ruptured to permit the emptying of the bag, the ruptured sleeve and end flap can be folded outwardly from the opening to form a pouring spout adjacent the opening.
