Description

  The present invention relates to a temperature deviation prevention / temperature adjustment material and a temperature adjustment method using the material. In particular, the structure of the material that can prevent the management temperature of the package from deviating or that can adjust the management temperature of the package without being affected by the outside air temperature for a long time, such as air transportation, and the material The present invention relates to a method for adjusting the temperature of a transported item using a slab.

  When freight such as pharmaceuticals that require temperature control is transported by air, in order to maintain the quality of such transported freight, for example, a predetermined temperature is maintained regardless of the outside air temperature for a long period of 72 hours. Had to manage to range. Also, when keeping cargo such as pharmaceuticals that require temperature control in a parking area (so-called ramp side) for parking aircraft, it is controlled within the specified temperature range regardless of the outside air temperature. There was a need to do.

  Pallets or containers used for transporting aircraft are called unit load services (units for aircraft units) or ULD (Unit Load Devices) by IATA (International Air Transport Association). With the introduction of large jet aircraft, various ULDs have been developed.

  A cargo container suitable for air transportation of pharmaceuticals etc. has a cargo storage room surrounded by a vacuum insulation panel, and a cooling evaporator or electric heating element arranged with the rear wall separated is used for cargo storage. A cargo-only container (ULD) that circulates the air inside the chamber is disclosed (for example, see Patent Document 1).

  In addition, as a thermostatic box suitable for air transportation of pharmaceuticals, etc., it is composed of an insulated outer box and an inner box that can accommodate the transported goods, and the first heat storage material is disposed on the outer peripheral portion of the inner box. 2 When the heat storage material is arranged on the outer periphery of the first heat storage material and the outside air temperature is higher than the management temperature of the transported goods, the second heat storage material lower in temperature than the first heat storage material is placed, and the outside air temperature is managed by the transported goods. There is disclosed a thermostatic box in which a second heat storage material having a temperature higher than that of the first heat storage material is disposed when the temperature is lower than that of the first heat storage material, and the transported product can be kept warm or cold in a predetermined temperature range (for example, see Patent Document 2).

  On the other hand, it is not limited to air transportation, but it is easy to attach and detach to industrial containers, and even when industrial containers are left outdoors for a long time, changes in the quality of container contents due to changes in outside air temperature An industrial container heat insulating cover that can be prevented is disclosed (for example, see Patent Document 3).

  By using the freight container disclosed in Patent Document 1 and transporting drugs requiring temperature control by air, the quality of the drugs requiring temperature control can be maintained regardless of the outside air temperature. However, air cargo generally has a unit charge for each type of container. And it is a fixed amount until the total weight of the cargo loaded in the container becomes a constant weight. That is, when the total number of unit cargoes loaded in a container is large, the container usage fee per unit cargo is low. On the other hand, when the total number of unit cargoes loaded in a container is small, the container usage fee per unit cargo becomes high.

  Under these circumstances, the transportation cost per unit cargo can be reduced if a plurality of cargoes are mounted on a pallet and transported by air in consideration of the weight and balance of the total number of cargoes without using containers. However, no material for temperature deviation prevention and temperature adjustment that manages the collective cargo at a constant temperature has been developed so far. By developing temperature deviation prevention and temperature adjustment materials that manage collective cargo that requires temperature control at a constant temperature, transportation costs for air transportation can be reduced.

  If the medicine is accommodated in the thermostatic box disclosed in Patent Document 2 and transported by air, the quality of the medicine requiring temperature management can be reliably maintained regardless of the outside air temperature. However, if a large quantity of medicines are divided into multiple thermostat boxes and transported by air, the purchase cost of the thermostat boxes and the transport charges due to the weight of the thermostat boxes will be added, so the transport charge per unit drug will increase. There is a problem.

  Reduce the transportation fee per unit drug if a low-cost, lightweight cardboard box contains medicines that require temperature control and materials for temperature deviation prevention and temperature control that manage these collective cargoes at a constant temperature can be realized. Is also possible.
