PROBLEM TO BE SOLVED: To provide a liquid chemical container which can suppress decomposition of a stored liquid chemical, and suppress damage of a container.SOLUTION: A liquid chemical container comprises: a container body on which, a cylindrical mouth part communicating inside and outside of a container, is formed； and a cylindrical nozzle whose base end side is fitted to a mouth part of the container body. The nozzle comprises an inner cylinder which is formed of a hard resin, and an outer cylinder formed of a resin which is softer than the resin forming the inner cylinder. The inner cylinder has an annular part which protrudes to outside of a radial direction on a base end, and the outer cylinder is arranged on an outer periphery of the inner cylinder on a side closer to a tip end side than the annular part. The annular part has a diameter expansion part whose outer diameter is gradually expanded from the base end side to the tip end side, an apex of the diameter expansion part, and a diameter reduction part whose outer diameter is reduced toward a tip end side, with the apex as a base point, and the apex contacts the inner peripheral face of the mouth part tightly, over whole periphery, and the diameter expansion part and the diameter reduction part are separated from the inner peripheral surface of the mouth part.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】収容された薬液の変質を抑制するとともに、容器の損傷を抑制することができる薬液容器を提供する。【解決手段】薬液容器は、容器の内外を連通する筒状の口部が形成された容器本体と、容器本体の口部に基端側が嵌入された筒状のノズルと、を備え、ノズルは、硬質の樹脂によって形成された内筒と、内筒を形成する樹脂よりも軟質の樹脂によって形成された外筒とを有し、内筒は、基端において径方向外側に突出する環状部を含み、外筒は、環状部よりも先端側において内筒の外周に配置され、環状部は、外径が基端側から先端側に向けて漸次拡径した拡径部と、拡径部の頂部と、頂部を基点として外径が先端側に向けて縮径した縮径部とを含み、頂部は、口部の内周面と全周にわたって密着し、拡径部及び縮径部は、口部の内周面から離間している。【選択図】図４
