<P>PROBLEM TO BE SOLVED: To provide a spout wherein the generation of a wavelike deformation on the flange section can be suppressed even when a carrying section for restricting the rotation of the spout is provided, and there is no leakage of a content liquid when being attached to a container opening section. <P>SOLUTION: This spout 10 for container which is manufactured by injection-molding or the like includes a thin-walled annular flange section 11, a cylindrical section 12, and the carrying section 15. In this case, the thin-walled annular flange section 11 is welded or bonded to the opening section B of a container A. The cylindrical section 12 is extended upward from the inner periphery of the thin-walled annular flange section. The carrying section 15 is held between a flange section 14 and the thin-walled annular flange section 11 on the lower outer periphery of the cylindrical section, and includes an outer peripheral surface 16 having a parallel surface which is regulated in one direction and an inner peripheral surface 18 having the same shape. A transverse cross-section of the carrying section is provided in such a manner that a difference in wall thickness t of the total periphery of the carrying section may be minimized. <P>COPYRIGHT: (C)2009,JPO&INPIT |
