Definitions

  • the present invention relates to a thermal insulating transport container. More particularly, the present invention relates to a thermal insulating transport container for transportation of temperature sensitive items, such as seafood, out of cold chain.
  • Known packaging for the storage and transportation of temperature sensitive items includes expanded polystyrene (Styrofoam) boxes and polyethylene coated or wax impregnated corrugated fibreboard boxes which are packed with a chilling material, such as ice, to keep the items chilled whilst out of the cold chain storage and delivery within the recommended temperature range (which for seafood is usually 2° C. to 8° C.).
  • Styrofoam expanded polystyrene
  • corrugated fibreboard boxes which are packed with a chilling material, such as ice, to keep the items chilled whilst out of the cold chain storage and delivery within the recommended temperature range (which for seafood is usually 2° C. to 8° C.).
  • expanded polystyrene boxes have a limited lifespan due to disintegration of the box during use.
  • expanded polystyrene poses an environmental hazard as polystyrene can break down into small pieces which are not appreciably biodegradable.
  • this type of packaging material tends to have poor barrier properties and consequently may be subject to contamination by its contents.
  • they typically require a single use plastic liner bag which is environmentally unsustainable.
  • the efficiency of use is limited as the boxes have fixed dimensions and can be bulky to transport and store when not in use as they are not collapsible. Further due to the fixed dimensions their usability is limited for items of non-standard size especially when it is not possible to break items up to fit the container (for food
