A nozzle for drip-feeding adapted to be inserted into a tubular spout neck portion of an eye lotion container which can prevent cracks at the spout neck portion due to a dimension error caused between the spout neck portion and the nozzle by change in room temperature or the like and provide tight sealing even if there is scratch or groove in the inner circumferential surface of the spout neck portion. This nozzle comprises an inserting main body having an inserting portion which corresponds to an inner circumferential surface (27) of a tubular spout neck portion (22) of an eye lotion container and has a diameter smaller than the diameter of the inner circumferential surface, and a fin-shaped sealing portion (16a) provided integrally and circumferentially of this main body and having an outside diameter slightly larger than the diameter of the inner circumferential surface. The outer edge portion (16c) of each fin portion is formed into a square edge shape having a square cross section, and when the inserting main body is inserted into the spout neck portion (22), each fin (16a) flexes so as to offset a dimension error, and in a case where there is a scratch in the inner circumferential surface (27), the square edge is brought into the scratch so as to sealing close the inner circumferential surface (27). |
