Definitions

  • the present invention relates to the protection of goods and products against either elevated or decreased temperature with respect to ambient temperature, during shipping or transportation in sea-freight shipping containers.
  • thermal insulation is required which slows the rate of change of the temperature within the container.
  • Thick blankets of wool or similar material and plastic bubble material can be used to provide thermal insulation.
  • a sleeve like liner can be used as a thermal insulator which is inflated using a motorised fan or blower.
  • Such an inflatable liner has the disadvantage that it can only be readily used where electric power is available.
  • Some liners are used where the walls of the liner are adhered to the walls of the container using double-sided tape, or hook-and-loop material. The effectiveness of such liners is reduced by the direct contact of the liner with the wall of the container. Owing to the direct contact between the liner and the container walls, heat is conducted from the walls to the insulation materials.
  • U.S. Patent number 5,638,979 discloses a bubble foil with a reflective surface. These types of bubble foil are bulky and heavy and cannot be effectively used in sea-freight containers.
  • an object of the invention is to provide a thermal insulation device for use in sea-freight shipping containers, having improved thermal insulation properties, and being easier to install.
  • a thermally reflective liner for providing thermal insulation within a container, the liner comprising :
  • a method for thermally insulating a container with a thermally reflective liner comprising:
  • a method for thermally insulating a container with a thermally reflective liner comprising:
  • Figures 1 to 3 show a first embodiment of a liner 20 which can be installed in a container 1.
  • the liner 20 is in the shape of a sleeve, with dimensions which substantially correspond to that of the container 1 into which the liner 20 is to be inserted.
  • the liner 20 has four long panels 25 which are each joined along the longest sides to the adjacent long panels 25, forming long seams 26.
  • the liner 20 has an approximately rectangular cross section.
  • An end panel 30 seals an end of the liner 20.
  • Four sealable panels 35 of rectangular cross section are each joined, along a long side, to the short sides of the liner 20. Thus, a sealable opening is formed in the liner 20.
  • Loops 40 are provided along the seams 45 of the liner 20. Hooks 15 are positioned along the vertices 18 of the container 1.
  • the end panel 30 is first positioned at the back end 5 of the container 1.
  • Four pieces of webbing material, such as cords 50, are used to retain the liner 20 in position inside the container 1.
  • a knot is made at the end of each of the cords 50, tying the cords 50 to rear tying points 6 at each corner on the back end 5 of the container 1.
  • Each cord 50 is then fed alternately through the loops 40 on the liner 20 and the corresponding hooks 15 on the container 1. Once the cord 50 has been fed through to the front 7 of the container 1, knots 55 are tied at the end of each cord 50, attaching the cords 50 to front tying points 11. Thus, the liner 20 is inserted into the container 1.
  • the four sealable panels 35 can be closed at the front end of the container to provide a thermal seal which completely surrounds the contents of the container 1.
  • the sealable panels 35 are provided with a ties 60 to securely close the liner 20.
  • Figure 4 illustrates another embodiment of the liner having different retaining means to retain the liner 20 in the container 1.
  • the container may still be provided with hooks 15 at the vertices 18 of the container 1.
  • the loops 40 in this embodiment are not as wide as the loops of the previous embodiment but are shaped more as eyelets.
  • the eyelets may be flexible, that is, made of a woven fabric, or stiffer where they are made of a metal or plastics.
  • Metal connecting hooks 71 may be either permanently attached to eyelets 40 or can be unhooked therefrom. Metal hooks 71 are designed to hook onto web 50 catching the lengths of web 50 between container hooks 15.
  • web 50 does not need to be constantly threaded and unthreaded from container hooks 15 and liner loops 40. Rather, the web may remain tied to the container at front and rear tying points 11 and 6 respectively and threaded through hooks 15.
  • the metal connecting hooks 71 are hooked onto the adjacent web 50 threaded through the container hooks 15. This allows for a much simpler and faster attachment process, particularly for inserting the liner into a container.
  • Connecting hooks 71 may be detachable from eyelets 40 or container hooks 15, or they may be permanently connected to either the eyelets 40 or container hooks 15 such that connecting hooks 17 are not misplaced.
  • the liner or container may include velcro loops that loop around web 50 and fold over to attach with itself and form a velcro loop.
  • FIG. 5 Another embodiment of the liner is illustrated in figure 5.
  • the bottom panel is missing such that there are only three long panels 25, an end panel 30 and only three sealable panels 35.
  • the resulting shape is a part tube with one panel missing. This embodiment is brought about because it is not always necessary or desirable to have a bottom panel lining the base of the container.
  • Liner loops 40 are still provided in this embodiment along the lower edge 72 of the side panels. This maintains the side panels firmly aligned with the side walls of the container.
  • some containers may be of irregular geometry, for example having more than four sides, such as five, and in these cases a liner may be purpose made for such containers along the lines of the above concept.
  • Such custom made liners may comprise more than four panels, such as five or six, forming a tube or part tube.
  • additional cord 65 is provided to retain the seam 70 (located between the uppermost long panel 25 and the uppermost sealable panel 35) to the container 1.
  • the liner 20 is made of a reinforced material such as a woven fabric, and further laminated with a thermally reflective material.
  • thermally reflective materials include aluminium and/or vaporised aluminium sheet.
  • the liner 20 is light weight and tough.
  • the liner 20 must be able to withstand the rough treatment of the forklifts and pallet jacks used to load/unload goods from the container 1 is an important characteristic of the liner 20.
  • the woven fabric provides the durability required of the liner 20, while the aluminium provides the thermal reflective surface.
  • the liner 20 When the liner 20 is inserted as described above, the liner 20 is positioned within the container 1 such that an air gap is formed on the long sides and top between the liner 20 and the container 1.
  • the thermally reflective surface of the liner 20 reduces heat transfer by thermal radiation to (or from) the air immediately adjacent to the liner 20.
  • the air gap between the container 1 and the liner 20 improves the thermal insulation by minimising conduction from the liner 20 to the container 1.
  • webbing material is used herein to encompass any suitable form of elongate flexible material including cord, rope, cable, chain, tape.
