Abstract: A portable storage container that consists of multiple compartments that are used to separate different components of a stored item. In separating out the components, the shelf life of the stored item is dramatically increased. The storage device is made from a plurality of polymeric film sheets that are connected through a perimeter seal that leaves a vacant space within the perimeter seal between the polymeric film sheets for creating multiple compartments. The compartments are separated through frangible sealing structures that are made up of a plurality of individual seals of varying types. When the device is operated, the frangible sealing structure is ruptured, therefore allowing the separated components to mix. Using a sealing structure made up of multiple seals ensures that the compartments remain separated when the storage container is subjected to harsh environmental conditions.
