A parallelepipedal flat-gabled package, especially an eared package with a medial seam, having an area in the gable that has been prepared such that it can be penetrated or separated along a closed curve and, once it has been penetrated or separated, will constitute a pouring hole. The package also has a plastic pour-out structure that has a flange surrounding the pouring hole, rigidly secured to the outer surface of the gable, and into the spout of which can be axially inserted a tube with a circumference that matches the closed curve. It also has a number of triangular teeth along the surface that faces the pouring hole, and a cap that can be repeatedly employed to close the spout, the inner surface of the package being coated with a hot-adhering film of plastic. The closure-flap cap is securely attached to the tube, by way of a connecting strip, and is articulated to the tab on the pour-out structure, which is in the form of a spout.
