A pizza saver is a device used to prevent the top of a food container, such as a pizza box or cake box, from collapsing in at the center and touching the food inside. A pizza saver is made of plastic and has three (sometimes four) legs. They are often white, and the common practice is to place one pizza saver in the center of the pizza before the box lid is closed for delivery.
The pizza saver is not re-used and is thrown away or recycled by the patron, although some people have found secondary uses for them such as egg holders when turned upside down.
