The vessel parts have a mating structure to facilitate selective attachment and separation, or may be permanently attached to one another. Optional outer lids engaged the rims independent of the engagement of the inner lids with the vessel parts. An annular band may be positioned around annular walls of the vessel parts to provide or aid in attachment of the vessel parts to one another.
