PROBLEM TO BE SOLVED: To provide a spout for a flexible packaging container in which an insertion end part of the spout is not collided with one end part in a non-sealed condition, hooked or bent thereby but smoothly inserted when inserting the spout in one open end part of a flexible packaging sheet in a non-sealed condition of the flexible packaging container on which the spout is mounted. SOLUTION: The spout for the flexible packaging container comprises a cylindrical part 1, a spouting flow passage 1a inside the cylindrical part 1, an outer end part 2 forming a spouting part outside a flexible packaging container P with a spout, an inner end part 3 inserted in the container P, an uneven part or a lid attachment part 4 such as a screw part to be screwed to fit a cap to cover the spouting flow passage 1a on the outer end part 2 side, and a flat shaped mounting part 5 having a flat surface expanded in a flat manner in the V-shape on both sides in the diameter direction of one cylinder over the predetermined width from the outer circumference of the cylinder on the inner end part 3 side of the cylindrical part 1. An outer circumferential edge part 6 of the inner end part 3 is a round-corner shape or a taper-inclined shape. COPYRIGHT: (C)2005,JPO&NCIPI
