PROBLEM TO BE SOLVED: To provide an expiration sampling container capable of simply sealing the container after sampling the expiration. SOLUTION: The expiration sampling container according to the present invention includes: a base cap 20 to be held to a mouth part 14 of a container body 10; a rotatable nozzle 30 for introducing blown expiration to an internal space M; an inflow pathway Kc located between an inner tube 21b and an inside annular wall 32b and changing over between the opening/closing of an inlet passage Ka by rotation of the nozzle 30; and an exhaust pathway Kd located between an outer tube 21e and an outside annular wall 32c and changing over between the opening/closing of an outlet passage Kb by the rotation of the nozzle 30. The inflow pathway Kc and the exhaust pathway Kd are so aligned as to change over according to a rotation angle of the nozzle 30, to at least one attitude among an attitude where both the inlet passage Ka and the outlet passage Kb are opened, an attitude where both the inlet passage Ka and the outlet passage Kb are closed, and an attitude where the inlet passage Ka is opened and the outlet passage Kb is closed.
