a box made of insulating material delimiting a compartment opened upwards having a volume less than 150 liters and able to contain the products, the box having a determined heat dissipation value;

a cover made of insulating material adaptable on the box to seal the compartment;

a diffusing divider wall interposed between the box and the cover to delimit with the cover, a chamber with a surface for receiving at least one refrigerated load emitting a heat value, the cover and the divider wall comprising complementary means for locking/unlocking with one another;

wherein the heat energy emitted by the refrigerated load and the thermal diffusion coefficient of the divider wall are adjusted such that, at determined transport and conservation temperatures and for a desired duration after receiving the refrigerated load and exposure of the product transport container to the transport temperature, the heat value diffused by the divider wall to the compartment is equal to, or at most 20% greater than the heat value dissipated by the box,

wherein, from a divider wall on which is placed the cover with pivoting capacity with respect to the divider wall and along a pivoting edge, the method comprises steps consisting of:

making the cover automatically pivot with respect to the divider wall to free up an access to the chamber for receiving the refrigerated load;

automatically pushing at least one refrigerated load inside the chamber wherein the chamber comprises:

means for supporting a divider wall on which is placed a cover;

means for automatically pivoting the cover;

means for supplying a refrigerated load and for pushing the refrigerated load inside the chamber.
