Our task was to develop a packaging concept that that could be assembled by a machine, that was of a shape that hadn’t been used before and that could adapt itself according to the volume of materials it was holding. Using diagonal slits, a pre-assembled, mechanically produced, foldable square box was able to adapt to different volumes. By changing the straight, diagonal slits to concave or convex alignment a softer shape can be developed and aslit window can be harmoniously introduced. The easy to use, re-sealable opening mechanism is the finishing touch to this packaging concept.
