The present invention provides a device for containing and a method of refrigerating, heating, and storing. The device comprises at least two containers each having a continuously formed rounded surface running from a bottom plane to a medial perimeter. The continuously formed rounded surface of one of the containers laterally extends beyond the medial perimeter of at least the two containers and extends over and laterally at opposite ends of the containers in a parallel relationship for suspending the one container within one of the other containers. A notched cap is sized for placement over and for substantially encapsulating the two containers. The continuously formed rounded surface of the one container laterally extends through and laterally beyond the notched cap.
