collapsable sandwich box
This sandwich box encourages dietary consideration, providing a convenient way to stay healthy. It was designed hypothetically for the company innocent, using their ethos at heart. The box is made from a recyclable plastic called TPE, the panels would be made from a harder grade and the flexible coating that allows the box to flex would be made out of a softer grade. The design expands up to 5cm to allow plenty of room for a sandwich, it folds flat to a thickness of only 1.5cm.
The entire lunchbox would be ultrasonically welded together, providing a water tight seal.
Unlike in the images above the panels would be fully coated in the softer grade, leaving no sharp corners. Unfortunately the model shown is made from paper and mount board.
