PROBLEM TO BE SOLVED: To solve such the problem that even when a discharge cap is removed, a container body cannot be refilled with contents.SOLUTION: A discharge container 1 is provided with: a container body 4 equipped with an outer container 3 housing an inner container 2 that shrinks and deforms as a content decreases; and a discharge cap 24 which is attached to a mouth 4a of the container body 4 and in which a discharge port 50 is formed. In the outer container 3, a suction hole 7c for sucking the outside air is formed between the outer container and the inner container 2. The discharge cap 24 is provided with: an outside air introduction hole 5d for communicating the outside with the suction hole 7c; a blocking plate 9 for blocking the mouth 4a and forming a communication hole 9d that communicates the discharge port 50 with an inside of the inner container 2; and a discharge valve 13 for opening/closing the communication hole 9d. In the sucking hole 7c, an air valve 10 which switches communication and block between the outside air introduction hole 5d and an outside air inflow gap S is attached. The air valve 10 is a check valve which permits a flow of fluid from an outside air introduction hole 5d side to the outside air inflow gap S and regulates a flow in the reverse direction. |
