Abstract
A method and apparatus in which a container is provided with a refrigeration facility. A holder for holding carbon dioxide snow is placed within the interior of the container so that the carbon dioxide snow is in gaseous communication with the interior of the container. The holder or a continuous wall region of the holder, constituting about 15% of the total wall area of the holder, is fabricated of a flexible material that is at least substantially impermeable to the carbon dioxide snow and permeable to gaseous carbon dioxide. Additionally, a combination container and holder is disclosed along with a combination holder and support structure. The support structure is attachable to the container to support the holder so that the carbon dioxide snow is in gaseous communication with the interior of the container.
