Abstract: A method for transport of one-unit packed products giving off moisture and requiring cooling without any direct contact with a cooling medium, e.g. crushed ice, with use of an outer packing means comprising a tray/box which opens upwards and has a cover and a double bottom comprising an upper bottom member with drainage apertures, and a lower watertight bottom member, and a sorbent for moisture placed in a space between bottom members. The one-unit products are placed in liquid tight trays/boxes opening upwards which are closed by covers provided with drainage apertures. One or a plurality of trays are placed with cover facing down in the case, whereupon cooling medium is provided on and, if desired, around the bottoms, and side walls of trays, and the case is closed by the aid of the cover. Moisture given off from the one-unit packed product, and any water from the melting cooling agent will flow down through drainage apertures of upper bottom member and will be absorbed by absorbent.
