PROBLEM TO BE SOLVED: To provide a droplet vessel with a check valve by which the backflow of ambient air into the vessel is prevented and the inside of the vessel is kept clean.SOLUTION: A droplet vessel 10 using in an inverted state comprises: a vessel body 11; a nozzle member 12 attached to an opening 11a of the vessel body 11; and a cap 13 to close the opening 11a of the vessel body 11. The nozzle member 12 has a cylindrical nozzle to discharge a content to a droplet in a downstream side and the check valve to prevent a fluid from flowing upstream in an upstream side. The droplet vessel 10 is a vessel for dropping down a chemical solution such as an ophthalmic solution and the like to an object.
