PROBLEM TO BE SOLVED: To provide a multi-chamber container in which a small container is housed in a container body, and the small container is more easily opened at the same time as opening of a storage portion on the container body side. A plurality of storage units, a discharge port connected to the storage unit, and a small container provided in the storage unit are provided. By increasing the pressure in the storage unit, the plurality of storage units and the small containers are A multi-chamber container that is opened and communicated with each other, and includes a weak seal portion that seals a part of the small container, and a first middle seal portion and a second middle seal portion that have higher sealing strength than the weak seal portion. The first middle seal portion and the second middle seal portion are arranged so as to face each other, and the tip of the first middle seal portion on the second middle seal portion side and the second middle seal portion are provided. Of the first middle seal part is close to the weak seal part, and the first middle seal part and the second middle seal part are close to each other in the weak seal part. A multi-chamber container that has a part that is inclined so as to be narrower. [Selection diagram] Figure 1【課題】容器本体内に小容器を収納した複室容器において、容器本体側の収納部の開通と同時に小容器がより開封しやすい複室容器を提供することを目的とする。【解決手段】複数の収納部と、収納部に接続された排出口と、収納部内に設けられた小容器と、を備え、収納部内の圧力を高めることにより、複数の収納部及び小容器は互いに開封連通される複室容器であって、小容器の一部分を封止する弱シール部と、弱シール部よりもシール強度が高い第１の中シール部及び第２の中シール部と、を備え、第１の中シール部と第２の中シール部とは対向して配置されており、第１の中シール部の第２の中シール部側の先端部と、第２の中シール部の第１の中シール部側の先端部とは、弱シール部に近接しており、第１の中シール部と第２の中シール部とは、互いの間隔が、弱シール部に近くなる程狭くなるように傾斜する部分を備えている、複室容器。【選択図】図１
