PROBLEM TO BE SOLVED: To provide an inner bag storage container in which an inner bag having a spout with four sides sealed can be easily thrown into an outer box, the strength of the outer box is reinforced, damages such as pin holes are prevented by suppressing the oscillation in the outer box, leakage or degeneration of contents is prevented, the amount of the remaining contents after the use is reduced as small as possible, and the waste volume can be easily contracted. SOLUTION: The inner bag storage container comprises an outer box and an inner bag member which is formed in a parallelepiped shape of the dimensions same as the dimensions of the outer box and accommodated in the outer box. The inner bag member comprises a four-side-sealed bag having a spout which is formed by overlapping two sheets each other and heat-bonding a peripheral edge portion of each sheet with the spout fitted to a center top part of one surface, and two frame bodies affixed across a center portion in the vertical direction of face and back outer surfaces of the four-side-sealed bag. The frame body has a left wing plate, a center plate and a right wind plate which are continuous to each other via two folds, and formed in a parallelepiped shape having the spout on an upper part by folding the frame body at the folds.
