A flexible 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 contoured 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 bonding in the vicinity of that pouch corner. The pouring spout is opened by cutting the pouch corner at an angle. The flexible walls of the pouch are reinforced in the vicinity of the pouring spout to prevent folding. The open spout is intended to be inserted in the open neck of a container to be refilled.
