Witness the magic of US Patent 7,051,919: The Pizza Box that Comes From the Future! It tears, it serves as plates, it folds, it saves the planet! Or something like that.
Called the Green Box, the top is perforated so it easily breaks into four plates in which you could serve everyone's favorite food. Meanwhile, the bottom is also perforated so you can fold it into a new box that conveniently fits in your refrigerator.
This is actually a great idea. Plus even if you finish the whole thing, it’ll be easier to fit in most garbage cans.
