ABSTRACT OF THE DISCLOSURE A flexible self-standing pouch made from at least one layer of plastic material bonded to form a closed inner chamber for storing liquid. Peripheral portions of the wall material are cortoured and then bonded to form a closed pouring spout at a corner of the pouch. The configuration of the spout is defined by the contour of the sealing in the vicinity of that pouch corner. The pouring spout is opened by cutting the pouch corner at an angle. The bonded peripheral edge has a generally rec- tangular contour except for an inwardly curved portion cor- responding to a recess in the wall material, which recess partly defines the spout configuration. This recess has a maximum height which is greater than the maximum depth measured in a direction transverse to the direction along which the height is measured. Further, the recess may either begin at the top of the pouch or at a point along the side which is spaced from the top. A juncture portion along the top of the pouch and a juncture por- tion along the rim of the recess define the configuration of the open pouring spout, which open spout is intended to be inserted in the open neck of a container to be filled.
