<P>PROBLEM TO BE SOLVED: To provide an ocular instillation nozzle structure which can achieve all the objectives of preventing liquid from remaining, preventing the liquid from overflowing and preventing the adhered chemical from pooling. <P>SOLUTION: A closing member 7b is fitted to the inside of a lower opening of a doughnut-shaped annular space 75 between an inner cylinder wall 72 and an outer cylinder wall 74 which are connected with each other by a flange 73 on their upper side from the underside for closing the lower opening. An inlet hole 711 having a minute diameter for communicating an inner space 20 of a container body 2 with a nozzle hole 71 is formed through the closing member 7b. Even when an eyedropper is inverted, the liquid in the inner space 20 never gains entrance to the doughnut-shaped annular space and the liquid can be prevented from remaining. The volume expansion of the liquid in the inner space 20 due to the difference in temperature can be reduced by the volume of the nozzle hole 71. <P>COPYRIGHT: (C)2012,JPO&INPIT |
