Adopting the principle of origami design, the lunchbox is able to fold nicely into the pocket size as shown in the video demonstration below:
Furthermore, we chose silicone as the main material for our lunchbox with the following considerations:
- It is flexible which is suitable for our folding mechanism.
- It is food-safe and chemically inert so it will not contaminate your food.
- It naturally has a smooth surface which inhibits the growth of bacteria.
- It can be easily moulded into the desired shapes.
- It is able to elongate by 450% before breaking.
