To provide a pump-type container with a bottom moving by an action of an atmospheric pressure, in which a useless space for storing/discharging contents is eliminated, the approximately whole contents of the container can be discharged to an external space and as little air as possible remains in an upper effective space in an initial state with the contents stored.
An annular space 10g originally present above a container body 10 and formed between a movable bottom 15, and a ceiling of the container body 10 and a downstream part of a cylinder 13 in a final state when the movable bottom 15 comes to the upper limit is equipped with a substitute ceiling 14 to have the annular space closed. The substitute ceiling 14 includes a flat surface 14e aligning with the upper surface 15a of the movable bottom 15 and a hole 14d for receiving the cylinder 13. In the initial state shown in the figure, there is little air left in a substantial content storage space 10h, and when the movable bottom 15 rises to the upper limit, the upper surface 15a comes into contact with the flat surface 14e of the ceiling 14. Thus the approximately whole contents in the container can be discharged to the external space.
