PROBLEM TO BE SOLVED: To provide a spout for a baglike container which offers sufficiently- hermetic sealing function at the time of re-sealing. SOLUTION: The stopper 3 of a spout 1 includes a finger-hold portion 9 and a stopper portion 5. The stopper portion 5 has a short diameter portion formed in the lower portion of a cylindrical part 14 continuing from the underside of the finger-hold portion 3, and a long diameter portion that is perpendicular to the short diameter portion and projects horizontally. The upper side 15 of the long diameter portion is a predetermined distance spaced from an annular projection 12 formed on the underside of the finger-hold portion. An engagement projection 13 is formed horizontally inward at the upper end of a tube 6 of a spout main body 2. A thin wall 4 is formed to connect the inner circumferential surface of the upper end of the spout main body and the outer circumferential surface of the leading end of the stopper 5. The upper side 15 of the long diameter portion of the stopper preferably defines an inclined surface in such a manner as to gradually bulge towards the longest diameter portion. At the time of re-sealing, the engagement projection 13 of the spout main body is held between the annular projection 12 of the detached stopper 3 and the upper side 15 of the long diameter portion. |
