PROBLEM TO BE SOLVED: To provide a method for manufacturing a multi-chamber container in which a plurality of storage portions and small containers are easily opened and contents are easily mixed. SOLUTION: A container main body 5 having a plurality of storage portions 9 and 11, a discharge port 7 connected to the storage portion 11 and a container main body 5 are partitioned into a plurality of storage portions 9 and 11 and the pressure in the storage portion is increased. As a result, the partition weak seal portion 13 that allows the plurality of storage portions 9 and 11 to open and communicate with each other, and the small container that is arranged in any of the plurality of storage portions 9 and 11 and is opened together with the opening communication of the partition weak seal portion 13. A multi-chamber container 1 comprising 15 and a first hooking portion L1 formed from one end side to a central side of the partition weak seal portion 13 to at least a part or a vicinity thereof, and a partition weak seal. A second hooking portion R1 formed at least a part or in the vicinity of the center side from the other end side of the portion 13 is further provided, and the first hooking portion L1 and the second hooking portion R1 are provided. Do not touch each other.
