PROBLEM TO BE SOLVED: To provide a double container whose synthetic resin inner soft shell stored in an outer container can be almost evenly recessed with a reverse line as a starting point in working a fluid discharge tool. SOLUTION: This double container 1 comprises a synthetic resin inner container 110 having a low rigid soft shell 113 and an outer container 130 having a storage part 131 from which a pump 120 exposes for storing the inner container 110. With the reduction of the internal pressure caused by the discharge from the pump 120 mounted on a mouth part 111, the soft shell 113 is reversed toward and adhered tightly to a hard shell 112 having a shape keeping characteristic with a reverse line L1 as a start point revolving in a longitudinal direction crossing a shoulder part, body part and a heal part. A pressing part 133 is provided for causing a reverse with the line L1 as a start point with the reduction of the internal pressure of the container 110 by pressing and deforming the stiffer heal part 113c of the soft shell 113 in a condition where the storage part 131 of the container 130 stores the container 110.
