Abstract: The present invention relates to a method and apparatus for maintaining products at an intended temperature during transport and storage at an ambient temperature deviating from the intended temperature. The invention features a container which holds the products and whose walls render heat transfer difficult. The container includes a main container body with a bottom and a side section that together define one or more integrated compartments suitable for storing a solidifiable substance. The container includes a lid which also has an integrated compartment for storing a solidifiable substance. When the lid is positioned on the main container body there is provided a solidifiable substance confinement enclosing the material storage space in the container from all sides.

Abstract: A method and apparatus for maintaining an intended temperature at or close to 0.degree. C. in products affected by variations in temperature, during transport and storage at an ambient temperature deviating from 0.degree. C., while using a container which holds the products and whose walls render heat transfer difficult. The method includes the steps of arranging adjacent the container walls, bottom, lid and the like compartments receiving water or a water mixture so as to provide a water-containing confinement enclosing the product-receiving space in the container from all sides. The container and the water in its wall compartments are then cooled so as to freeze the water. The products are then inserted in the container after it has been moved to a room having a temperature adapted to the products. The container is then closed and used for the transportation and/or subsequent storage of the products.
