PROBLEM TO BE SOLVED: To provide a spout B for a flexible container A which is fixed to the mouth 2 of the container A to extract the content therefrom, and allows the efficient discharge of the content with less residues. SOLUTION: The spout B comprises a spout body 10 whose outer periphery is welded to the container mouth 2, and a guide body 11 which is extended vertically from the spout body 10 into the container A. The guide body 11 is of a semitubular shape, whose upper edge center is located on the periphery of a lower end opening of the spout body 10 and is coupled to the spout body 10, and which has a pair of opening-expanding boards 22 on both sides. The opening-expanding boards 22 are expanded when necessary to allow the efficient extraction of the content. COPYRIGHT: (C)2006,JPO&NCIPI
