A disposal-bag system attached to or formed at least partially by a disposable object (e.g., a diaper) includes a container that houses a disposal bag folded into a compact arrangement. The container is generally thin and flat and sized for storing the bag, and the bag is sized for holding the disposable object that the system is used with. And the bag is at least partially removable from the container so that the disposable object can be placed into it for disposal. In use, the container is opened, the bag is extended from the container and opened, the disposable object is grasped by reaching through the bag, the bag is inverted to now hold the disposable object, and the bag is closed and disposed of. In this way, the disposal-bag system provides a convenient, sanitary, and self-contained method of disposing of soiled diapers or other disposable objects.
