The bag is positioned within a tubular folding box which is closed at the bottom and which has, at its upper end, closure flaps hinged to three of the sidewalls. One of the closure flaps is adhesively secured to the sealed end of the inner bag so that when the adhesively secured closure flap, or a portion thereof, is torn away the inner bag is automatically opened and a pouring spout is formed.
