  • the seafood is packed in rectangular boxes, preferably made of an EPS material and/or fiberbased corrugated cardboard. These are then stacked on pallets so that it is possible to transport large quantities at a time.
  • the size of the boxes can vary, but the basic shape is a bottom, a lid and four walls that are placed 90 0 in relation to each other. The reason for this characteristic shape is that they should be easy to stack.

  • PCM are passive cooling materials that store energy and emit energy at certain temperature thresholds.
  • Water is a PCM that stores energy in solid form and provides energy at +/- 0 0 C in liquid form.
  • PCMs are materials that absorb energy, store energy and emit energy with different temperature thresholds in a closed environment forming convection with air currents between materials with a difference in temperature.
  • the principles of this invention are based on convection between surfaces of different temperature direct or indirect contact physical contact between two separate PCM units.
  • the outer surfaces of the lid (and / or box) are loaded with dedicated PCM cooling material which is coated with active energy supply with cold air.
  • the other PCM material is sealed in cassettes / bags / ++ with bubble wrap to prevent direct contact and icing in the product.
  • the bubble wrap can be completely or partially opaque so that a "mini convex zone" is deposited on the product.
  • the product can be completely wrapped in bubble plastic and protect against outer bottom surface, wall surfaces and PCM cassettes.
  • Figure 1 is a perspective view of an embodiment of the present invention where one can see a box with a lid, in which the box has straight sides.
  • the box includes a rectangular box. This box has sides that are 90 0 apart. At the top of the box there is a lid. This lid covers the opening of the box at the top. A set of bricks is placed on top of the lid. This means that if an additional box is placed on top of or around the first, the spacer blocks ensure that there is a vertical and horizontal separation of air between each box. Alternatively, the bottom of the box may have bricks positioned in each corner and centered on each longest long side bricks for vertical lifting.
  • This solution makes it possible to circulate air on all sides of each box even if they are stacked tightly together on a pallet. By placing spacers on the lid, it is possible to create spacing between boxes that are stacked.
  • spacers there are two types. Comer spacers located in each corner of the lid. Furthermore, there are side spacer blocks that are placed on each long side of the lid.
  • the blocks are designed so that they protrude over each side of the lid. This ensures that boxes placed next to each other are not placed right next to each other. Furthermore, the spacer blocks protrude above the top. This ensures that boxes stacked on top of each other are placed so that there is a space between the boxes where the active refrigerant can circulate around the boxes.
  • the blocks may further have a raised edge around the outer edge of the block. This ensures that boxes can be stacked securely on top of each other without being displaced in the lateral direction.
  • the lid may further have at least one hole.
  • a plug can be placed in this hole.
  • This plug can have the shape of a mushroom. In the center of the plug there is a channel.
  • This duct can be filled with a passive coolant.
  • the passive coolant in the plug ensures that the cooling effect from the active coolant is transferred to a platform located inside the box in close contact with the goods in the box or a packaging the goods are packed while they are stored in the box.
  • This platform can be made of a material that easily transmits cooling effect from the refrigerants to the goods. This material may be in the form of a cell located between two outer layers, these cells may be filled with the passive refrigerant.

Circulation maintains a constant optimal ambient temperature zone with cold pressure on the product and the temperature zone; - minus -1.5 0 Celsius to +/- 0 Celsius on the product without time limit.
  • the advantages of an optimal temperature zone are longterm durability, reduced bacterial growth and better product quality.
  • the new thing is the choice of materials in the packaging that can e.g. be honeycomb cores with side layers and thus make a disc / plate construction with cavities; -or cavities can e.g. be between walls in a structure.
  • Corrugated sheets with studs between two side layers form a mat with cavities.
  • a corrugated plate comprising a center-placed cam panel and glued to the outer layer which forms two separate rooms / chambers.
  • the shapes of the mat can fill the entire cavity between the two side walls that form the panel and / or partially so that it is positioned to optimally accommodate critical load zones or load points in the panel.
  • PCM materials Phase Change Materials
  • PCM has the property that at a given temperature, e.g. Tl, switches to solid phase and at another given temperature, T2, switches to liquid phase. This gives the material a dedicated temperature zone between Tl and T2.
  • Tl and T2 thus forms a dedicated temperature zone with two limit values that define optimal conditions for transport and storage of the product.
  • a cold bridge is created between the outer surfaces of the shell packaging and the inner surfaces.
  • an active refrigerant e.g. cold air on the outer surfaces of the packaging, the PCM material will transport the heat away from the product via the inner surfaces of the box to the outer surface of the box to the circulating air around the box. This heat will then be transported away.
  • This solution also describes how it is possible to supply / transfer energy to a product in a closed package.
  • the system works by keeping the PCM material in a phase by regulating the temperature around the box.
  • the temperature around the box is maintained by using an active refrigerant such as air regulated to a certain temperature range.

  • the PCM material is integrated in the shell packaging of the box with contact to the outer and inner surfaces so that energy can be supplied with e.g. air circulation on the outer surfaces of the packaging and that the PCM material is in direct contact with the inner surfaces of the shell packaging. Added cold energy via the PCM material to the inner surfaces of the packaging and further to the air inside the packaging is thus possible. This stabilizes and provides a desired temperature zone which in transport of e.g. salmon -1.5 0 C to -0.5 0 C.

  • the bag can also be filled with a passive coolant. The bag ensures a good transfer of the cooling effect to this platform.
  • the e-platform can be made of a material that easily transmits cooling effect from the refrigerants to the goods. This material may be in the form of a cell located between two outer layers, these cells may be filled with the passive refrigerant. This platform ensures that the cooling effect spreads over the entire contents of the box.
  • Figure 5 is a cross-section of an alternative embodiment of the invention where the plug and the bag are designed as a part.
  • This makes it possible to fill the bag with coolant via the hole in the plug.
  • the hole in the plug leads to the inside of the bag.
  • the bag rests on a plate.
  • This plate has two functions, it helps to transfer the cooling effect to the goods to be cooled. In addition, it can act as a protective layer between the bag filled with refrigerant and the item. This solution can ensure that the cooling effect is transferred as efficiently as possible to the goods inside the box and it can ensure that the product is spared from damage that may be caused by the refrigerant and the cooling effect it has.
  • the plug itself rests over the hole in the lid, where the stem with the bag connected is guided down into the hole.
  • the top of the plug rests over the opening in the lid and completely covers this opening. In the center of the top there is an opening. This opening leads down to a channel in the trunk of the plug.
  • the bag is attached to the lower part of the stem on the plug. Alternatively, the bag can be attached to the underside of the top of the plug to ensure a good attachment between the plug and the bag and to act as an insulator on the stem of the plug.
  • Figure 6 describes a cross-section of an embodiment of the invention in which the entire box is illustrated.
  • the lid has a hole.
  • a plug rests over the hole.
  • the top of the plug is attached to a stem that goes through the hole in the lid.
  • a bag is attached to the end of the trunk.
  • a channel runs through the center of the plug. This channel leads to the inside of the bag.
  • the duct makes it possible to fill the inside of the bag with coolant.
  • the bag rests on a plate.
  • the plate separates the bag from the items inside the box.
  • the plate can ensure an even distribution of cooling effect over the goods in the box.
  • the plate can ensure that the goods are not damaged by the cooling effect of the coolant.
  • the plate rests directly on the goods.
  • the items can be placed arbitrarily inside the box or they can be placed according to a specific pattern to ensure the best possible cooling effect.
  • the space between the items can be filled with a refrigerant.
  • the items rest on one or more air- filled blisters.
  • These air- filled bladders ensure that the cold does not disappear via the bottom of the box.
  • the air-filled bladder e can be part of the bottom of a plastic bag.
  • the items are thus in this plastic bag and on the air-filled blisters.
  • the plastic bag can also be equipped with a handle. This solution makes it possible to lift the items in and out of the box without having to touch the item itself.
  • the blisters can be in the form of bubble wrap or sausages filled with air.
  • the walls of the box as well as the lid and plate resting on the goods can be designed as described in figure 3. This will ensure that the cooling effect is as favorable as possible.
  • This is an alternative embodiment and any combination of the plate walls and the lid can be designed as described in figure 3. In yet another embodiment, none of the walls need be made as described in figure 3.
  • the box can also have support pillars that extend the entire height of the box.
  • the support pillars can be located in the corners of the box, or they can be located in the middle of the long sides. Alternatively, they can be located both in the comers and in the middle of the long sides.
  • the support pillars can thus correspond to the spacer blocks on the lid. The support pillars and spacers will thus give the box extra strength so that it can withstand the weight of a majority of full boxes stacked on top of it.
  • the support pillars can be inside the box.
