PROBLEM TO BE SOLVED: To prevent a partition from being erroneously peeled off and to seal and unseal the partition when required by a simple operation. SOLUTION: The multiple-chamber container 1 has a bag 2 including an outlet 6. The bag 2 is constituted of a flexible sheet material 25, and its interior is partitioned into a first space 3 and a second space 4 by a partition 5 which is fused as a strip. A relation of 0.3<=P2/P1<=0.8 is satisfied where P1 refers to a pressure in the first space 3 (with a head pressure eliminated) when the partition 5 begins to peel with a pressure applied to the space 3 while a liquid 30 is received in the first space 3 and the container 1 is placed horizontally, and P2 refers to a pressure in the first space 3 (with a head pressure eliminated) when the partition 5 begins to peel with a pressure applied to the space 3 while the liquid 30 is received in the space 3 and the container 1 is vertically hanging so that the first space 3 is above the second space 4. |
