PROBLEM TO BE SOLVED: To provide a multiple-chambered container which can smoothly mix solid such as powder and grains contained in one chamber with other materials contained in other chambers.;SOLUTION: A multiple-chambered container includes: a first bag part 10 including a front surface part 11, a back surface part 12 and a pair of side surface parts 13 of a gusset structure, in which the front surface part 11, the back surface part 12 and the side surface parts 13 are joined at the upper end edge and the lower end edge, on at least one side of the upper end edge and the lower end edge, there is an unsealed part; and a second bag part 40 which has a front surface part 41, a rear surface part 42, etc., and an opening part on a part of the peripheral edge. Of the opening part, the front surface and the back surface are sealed in a separable manner, the opening part is inserted into the unsealed part, the front surface part 41 is sealed to the front surface part 11, and the rear surface part 42 is sealed to the back surface part 12, and at least, is sealed to the side surface part 13 in the area between the side edge of the second bag and a central position with a determined distance from the side end edge in the width direction. And the rear surface part 42 and the back surface part 12 may be sealed, and the front surface part 41 and the side surface part 13 may be sealed.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
