The lunch-box available on the market needs to be washed every time using it, however, washing boxes becomes very inconvenient for those who use lunch-boxes frequently. Considering these, this design is to make the bottom of the lunch-boxes another storage space especially for fresh-keeping bag. The fresh-keeping bag wil be designed to independent ones, each could be rolled into a small volume, everytime you take one bag you won't make the rest of the bag dirty in case that your hands are greasy and smear. The bag-taking device at the bottom is from modern tubularis box, that is when you open the small cover you can take out one piece.
