Definitions

  • This presentation relates to the field of transport of refrigerated food products, in particular a refrigerant container for transporting these products.
  • the delivery of these heat-sensitive products, in an environment under controlled temperature, is generally carried out using refrigerated vehicles formed by an insulated container having insulating walls, and by an individual cold production device making it possible to maintain the container. at predetermined temperatures.
  • refrigerated vehicles formed by an insulated container having insulating walls, and by an individual cold production device making it possible to maintain the container. at predetermined temperatures.
  • These vehicles are often bulky and expensive, and use non-renewable energy resources. It is also possible to have individual boxes closed and refrigerated in a traditional vehicle. However, repeated opening and closing of these individual cases during delivery is not possible.
  • the transport of these products can also be carried out using a refrigerating container with a rigid shell on casters, whose ratio between its weight and its useful volume is not optimal and makes in particular difficult its manual insertion in a traditional vehicle.
  • the present disclosure relates to a refrigerating container configured to store food products and to be inserted in a dry vehicle, characterized in that it comprises a plurality of thermal insulation panels assembled together so as to form a closed internal enclosure, l internal enclosure having a volume greater than 100 liters, preferably greater than 300 liters, more preferably still greater than 500 liters, the container comprising at least one door, each panel being covered on its internal face and / or on its external face by a cover, the container comprising a conductive support forming, with at least one of the insulation panels, an internal compartment in an upper part of the internal enclosure, the internal compartment being configured to accommodate at least one cooling plate, and the support conductor being configured to conduct the temperature emitted by the cooling plate.
  • Food products that can be stored in the container include in particular heat-sensitive products, that is to say refrigerated or frozen products which must not exceed a predefined temperature in order to comply with regulatory requirements.
  • dry vehicle is meant a traditional vehicle, such as a utility vehicle, without an independent refrigeration device.
  • the container can be placed in such a dry vehicle by hand, or removed from this vehicle.
  • the food products can be boxes housing refrigerated and / or frozen food, several of these boxes being able to be placed in the container.
  • the door can pass from a closed position, in which the internal enclosure formed by the container is hermetically closed, to an open position by rotation about a vertical axis, allowing access to the boxes placed in the container.
  • the internal enclosure has a volume greater than 100 liters.
  • These envisaged volumes of the container make it possible to facilitate the transport of the latter, and in particular allow the container to be placed in traditional dry vehicles such as utilities, while allowing the storage of a large quantity of food products in the internal enclosure.
  • they also allow a man to enter the container in order to access products placed at the bottom of the container and difficult to access, for example.
  • the container of this presentation ensures compliance with regulatory requirements related to maintaining the temperature of the products transported.
  • the internal face of the panels is the face disposed towards the inside of the internal enclosure, and the external face of the panels is the face of the panels opposite the internal face, and directed towards the outside of the container.
  • the cover placed on and covering the internal face and / or on the external face of each panel can make it possible to improve thermal insulation.
  • the conductive support can be a platform separate from the insulation panels, and fixed to the container inside the internal enclosure so as to form an internal compartment in an upper portion of the internal enclosure.
  • the internal compartment thus formed between the conductive support and the upper insulation panel can accommodate at least one refrigerating plate such as an eutectic plate.
  • This refrigerating plate can comprise an eutectic liquid which can be: water comprising eutectic compounds based on salts and / or viscous compounds, paraffin, or PCM (from the English "Phase Change Material", it i.e. phase change materials), which can diffuse a temperature in the internal enclosure.

  • the presence of this support and of this internal compartment form a solid, autonomous and passive structure for the diffusion of cold allowing, by means of the cooling plate, to maintain the temperature within the internal enclosure at desired values.
  • This device has the advantage of keeping the products it contains at a passively desired temperature, without the need for the presence of an active cold source, for example, a motorized refrigeration system.
  • This container is therefore particularly suitable for the delivery of heat-sensitive products,
  • the thermal insulation panels are assembled so that the container comprises an upper wall, a lower wall, and four side walls, the at least one door of the container being arranged on at least one side wall. .
