  • a refrigerated container for transporting perishable goods such as food or medicines
  • a refrigerated unit load device for transport by air i.e. a container of the type commonly known as a ULD (Unit Load Device).
  • the category of unit load devices includes for example pallets and containers which are used for loading goods of various types on means of transport and in particular on aircraft.
  • Using a unit load device makes it possible to load large quantities of goods with a single unit, which makes it possible to optimize the time and manual labor needed for loading and unloading the aircraft.
  • Unit load devices and other refrigerated containers are normally used for transporting goods that need to be kept within a certain temperature range in order to not perish, such as for example medicines and food.
  • the solutions that are used for providing unit load devices and other refrigerated containers can be grouped into three categories: active solutions, semi-passive solutions, and passive solutions.
  • the container In active solutions, the container is provided with a refrigeration apparatus that must be powered continuously by mains electricity or by batteries. These conventional active solutions have the disadvantage that the operation of the refrigerated container depends on the availability of mains electricity; otherwise its capacity is limited by batteries. Furthermore the presence of a dedicated refrigeration apparatus makes these containers complex and expensive to produce, maintain and certify for compliance with IATA regulations, under which they are considered part of the aircraft.
  • the refrigerated container contains, inside the walls, a heat storage material such as a phase change material, and the container must be kept in a cold room for a period of time sufficient to freeze the heat storage material (in general at least 24 hours) before each trip.
  • the heat storage material can be contained, instead of in the walls, in removable thermal packs which are frozen separately in a cold room and then installed along the walls of the refrigerated container.
  • the aim of the present invention is to provide a refrigerated container that is capable of solving the problems and overcoming the limitations of the above-mentioned prior art.
  • an object of the present invention is to provide a refrigerated container that, in use, does not entail logistical efforts or the problems of safety, explained above, that are typical of the known passive and semi-passive solutions.
