PROBLEM TO BE SOLVED: To provide an eyedropper with a simple structure where pressure difference between atmospheric pressure and the internal pressure of a container is relaxed when using eye-drops, the excessive spout of a content fluid to outside is prevented, a discharge amount is exactly controlled and the characteristics of the content fluid can be reflected on design.SOLUTION: A discharge part 3 of an eyedropper 1 of the first embodiment comprises: a nozzle part 10 a first valve seat 20 a first valve body 40 a plurality of plate-like parts 43 as elastic members a second valve seat 50 and a second valve body 60. The first valve body 40 is separated from the first valve seat 20 by increasing the internal pressure of a container 2 and then an inside 9 of the container 2 and a flow passage 15 are communicated. The second valve body 60 interlocking with the first valve body 40 is separated from the second valve seat 50 and then the flow passage 15 and a discharge port 14 are communicated.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】点眼時における大気圧と容器の内圧の圧力差を緩和して、内容液が外部に過剰に噴出することを防止し、吐出量を正確にコントロールできるとともに、内容液の特性を設計に容易に反映できるシンプルな構造の点眼容器を提供すること。【解決手段】第1実施形態の点眼容器1の吐出部3は、ノズル部10と、第1弁座20と、第1弁体40と、弾性部材としての複数の板状部43と、第2弁座50と、第2弁体60と、を備え、容器2の内圧の上昇によって、第1弁体40が第1弁座20から離間して容器2の内部9と流路15を連通し、第1弁体40と連動する第2弁体60が第2弁座50から離間して流路15と吐出口14を連通する。【選択図】図6
