<p>PROBLEM TO BE SOLVED: To prevent crazing at a mouth/neck part of an eye-lotion container, which is caused by an error in size, etc., between the mouth/neck part and a nozzle due to fluctuations in room temperature, etc., and seal an inner peripheral face of the mouth/neck part even in the case where there are flaws, grooves, etc., on the inner peripheral face thereof, in a nozzle for dropping eye-lotion which is inserted into a cylindrical mouth/neck part of an eye-lotion container. SOLUTION: A nozzle comprises a main body of an insertion part corresponding to an inner peripheral face 27 of a cylindrical mouth/neck part 22 of an eye-lotion container and having a diameter smaller than that on the inner peripheral face 27 and fin-like seal parts 16a provided integrally with the main body in the peripheral direction thereof and having an outer diameter slightly larger than that on the inner peripheral face 27. An outer edge 16c of each fin is formed into an angular edge having a cross-sectionally quadrilateral shape and, when the main body of the insertion part is inserted into the inside of the mouth/neck part 22, each fin 16a is deflected to absorb an error in size. Further, in the case where there are flaws and the like on the inner peripheral face 27, the angular edges 16c enter the flows and the like to seal the inner peripheral face 27.</p> |
