To store food in a space-saving manner, this food container flexibly collapses or extends to the needed size. Made of food-safe silicone, the container is non-breakable and offers a maximum capacity of 600 ml. After filling, the height of the container can be reduced as needed by partially squeezing out the air, which also extends the shelf life of the food. After use, the jar can be collapsed down flat for space-saving storage.
