A multi-compartment container, comprising: a burst resistant outer flexible pouch formed from a flexible, liquid-impervious material, wherein said outer flexible pouch further includes an expansion pleat at a bottom end to provide a stand-up pouch, said expansion pleat including multiple folds on each side of a downward extending sealed edge; an inner packet, substantially enclosed within said outer flexible pouch, and sharing at least a portion of a common top edge with said outer flexible pouch, said common top edge providing a common opening for filling of said outer flexible pouch and inner packet prior to sealing both the outer flexible pouch and inner packet along said common top edge, wherein said inner packet contains at least one substance for mixing with a material contained within the outer flexible pouch; said inner packet being operatively linked to an anchor point on the downward extending sealed edge of the expansion pleat of said outer flexible pouch, wherein a force applied to said anchor point causes the tearing of the inner packet and mixing of the at least one substance in the inner packet with the material in the outer flexible pouch without direct access to the inner packet.
