A multi-compartment container structure has individual containers connected together. All the individual containers can have the same size and shape, and each has a flat base wall. Each of the individual containers is joined to immediately adjacent containers at wall edges of the flat base wall. The joints have a greater flexibility relative to the flat base wall. The flat base wall of each individual container lies in the same plane when the multi-compartment container structure is in an unrolled state. Each flat base wall of the individual containers lies in different parallel planes when the container structure is in a rolled-up state. The combination of flat base walls of the individual containers forms a multi-planar exterior of the container structure when the container structure is in the rolled-up state. The individual containers have watertight and airtight caps that are positioned adjacent each other when the container structure is in the rolled-up state.
