A container and lid combination includes a container having a bottom surface, an opening, a top edge surrounding the opening, and an attachment mechanism provided on the bottom surface, and a lid engageable with the top edge of the container to cover the opening. The lid may include an attachment mechanism provided on its inside surface that is engageable with the attachment mechanism of the bottom surface of the container. The lid is attachable to the bottom surface of the container in a nested state via engagement of the respective attachment mechanisms. Another attachment mechanism may be provided on the outside surface of the lid that is engageable with the attachment mechanism of the bottom surface of the container. The lid is attachable to the bottom surface of the container in a nested state and/or in an inverted state via engagement of the attachment mechanisms. A set of such container and lid combinations may be nested together. Furthermore, in a set of container and lid combinations, the base of the container of one container and lid combination may be attachable to the outside surface of the lid of another container and lid combination, to facilitate transporting of the container and lid combinations.
