PROBLEM TO BE SOLVED: To provide a fluid container which can prevent as much as possible the leak of a fluid from the center through hole of a communicating member when a cap member is not closed on a cover body in a proper posture. SOLUTION: In forming this fluid container, on a dome shape cover body 34 formed freely mountable on a container main body, a cap member 36 is mounted freely openable. By closing the cap member 36 on the cover body 34, the opening 17 of a short tubular communicating member 40 formed in the cover body 34 is closed by a protrusion 37 protrusively formed on the inner face of the member 36. On the top face 43 of the communicating member 40, a flexible resin cylindrical brim part 55 is standingly formed. When the cap member 36 is closed, the brim part 55 of the member 40 is elastically deformed by the protrusion 37. |
