Witness the magic of US Patent 7,051,919: The Pizza Box that Comes From the Future! It tears, it converts to 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 can't come soon enough, even while it will never serve any purpose in my home, where we fight to the death for the last slice.
