<P>PROBLEM TO BE SOLVED: To provide a dropping preservation container which is prevented from contacting with outside air at a minimum. <P>SOLUTION: A container 1, a dropping nozzle 2 and a pressurizing section 3 which pressurizes for drop of a fluid from the dropping nozzle 2 are installed. The dropping nozzle 2 comprises a base section 21 equipped with a dropping hole 20 in the center, a plurality of supplying slit-forming sections 22 located in a concentric fashion for forming approximately cylindrical supplying slits around the dropping hole 20, a floating valve 23 which moves up and down while constantly contacting with each ends of the supplying slit-forming sections 22, and a trunk 24 covering the supplying slit-forming sections 22 and the floating valve 23 around the outside of the base section 21. The trunk 24 comprises a locking section 25 which holds the floating valve 23 among the supplying slit-forming sections 22 by restricting its movement. Additionally, the base section 21, the supplying slit-forming sections 22 and the trunk 24 are composed as a unit by a resin. The pressurizing section 3 comprises a sealing member 30 which pressurizes the inside of the container. <P>COPYRIGHT: (C)2007,JPO&INPIT |
