Abstract

The present invention relates to a container provided with heat insulation means (8), characterized in that the heat insulation means (8) are removable and consist of a partition having a multilayered structure, or films, arranged between the wall of the tank (5) and at least the walls of two of the above-mentioned sides (2, 2′) as well as the upper surface (4) of the container (1). The invention further relates to the use of such heat insulation means (8) in a conventional container (1).

First claim

The invention claimed is:

1. A thermal insulator for a container, comprising: a thermal insulator partition, the thermal insulator partition comprising a multilayer structure including at least three thermoplastic and/or thermoset films and a metallic film, wherein at least one of the at least three thermoplastic and/or thermoset films comprises an air bubble structure, wherein: the thermal insulator partition is removably securable to an inside surface of the container so as to provide a first air chamber between the thermal insulator partition and the inside surface of the container and a second air chamber between the thermal insulator partition and a reservoir placed within the container, wherein said reservoir contains organic peroxides; the thermal insulator partition is removably securable to the inside surface whether the reservoir is present within the container or absent from the container, wherein the thermal insulator partition further comprises a plurality of catching points configured to mechanically fix the thermal insulator partition to engagement points on the container in order to keep the thermal insulator partition taut and maintain the first air chamber and/or the second air chamber at a substantially constant volume when mechanically fixed to the container.

2. The thermal insulator of claim 1 , wherein:
the container comprises a first side, a second side, a top surface, and a bottom surface,
the thermal insulator comprises a plurality of thermal insulator partitions, each thermal insulator partition capable of being removably securable to one of the first side, the second side, the top surface, and the bottom surface.

3. The thermal insulator of claim 1 , wherein the first air chamber is at least one centimeter and the second air chamber is at least two centimeters.

4. The thermal insulator of claim 1 , wherein each catching point comprises a hook configured to engage a corresponding engagement point positioned on the inside surface of the container.

5. The thermal insulator of claim 1 , wherein each catching point of the thermal insulator is configured to protrude from the thermal insulator partition and is at least partially surrounded by a thermally insulating material.

6. The thermal insulator of claim 1 , wherein at least one of the at least three thermoplastic and/or thermoset films comprises polyethylene and at least one of the at least three thermoplastic and/or thermoset films comprises polyester.

7. The thermal insulator of claim 1 , wherein the metallic film has a heat reflecting capacity of at least 95%.

8. The thermal insulator of claim 1 , wherein each of the at least three thermoplastic and/or thermoset films has a thermal conductivity below 0.1 W m-1 K-1 at 20° C.

9. The thermal insulator of claim 1 , wherein each of the at least three thermoplastic and/or thermoset films has a thermal conductivity below 0.05 W m-1 K-1 at 20° C.

10. A method for providing thermal insulation for a reservoir positioned in a container, the method comprising: removably securing a thermal insulator partition to an inside surface of a container so as to provide a first air chamber between the thermal insulator partition and the inside surface of the container and a second air chamber between the thermal insulator partition and a reservoir placed within the container, wherein the reservoir contains organic peroxides, wherein the thermal insulator partition comprises multilayer structure including at least three thermoplastic and/or thermoset films and a metallic film, wherein at least one of the at least three thermoplastic and/or thermoset films comprises an air bubble structure, wherein the thermal insulator partition is removably securable to the inside surface whether the reservoir is present within the container or absent from the container, wherein removably securing the thermal insulator partition comprises mechanically fixing the thermal insulator partition to the inside surface of the container via a plurality of catching and engagement points which keep the thermal insulator partition taut and maintain the first air chamber and/or the second air chamber at a substantially constant volume.

11. The method of claim 10 , wherein the container comprises a first side, a second side, a top surface, and a bottom surface, the method further comprising:
removably securing a first thermal insulator partition to the first side, a second thermal insulator partition to the second side, a third thermal insulator partition to the top surface, and a fourth thermal insulator partition to the bottom surface.

12. The method of claim 10 , wherein the first air chamber is at least one centimeter and the second air chamber is at least two centimeters.

13. The method of claim 10 , further comprising at least partially surrounding each catching point with a thermally insulating material.

14. The method of claim 10 , further comprising filling the second air chamber with a refrigerating gas.

15. A system comprising a thermal insulator and a container, wherein the system is configured for transporting heat-sensitive peroxides, wherein the thermal insulator comprises a thermal insulator partition, the thermal insulator partition comprising a multilayer structure including at least three thermoplastic and/or thermoset films and a metallic film, wherein at least one of the at least three thermoplastic and/or thermoset films comprises an air bubble structure, wherein the thermal insulator partition is removably securable to an inside surface of the container so as to provide a first air chamber between the thermal insulator partition and the inside surface of the container and a second air chamber between the thermal insulator partition and a reservoir placed within the container, wherein the reservoir contains organic peroxides, wherein the second air chamber is filled with a refrigerating gas.

16. The system of claim 15 , wherein the system further comprises a plurality of catching and engagement points configured to mechanically fix the thermal insulator partition to the container in order to keep the thermal insulator partition taut and maintain the first air chamber and/or the second air chamber at a substantially constant volume when mechanically fixed to the container.

17. The system of claim 15 , wherein the thermal insulator partition comprises a first thermal insulator partition configured to be removably securable to a first side of the container, a second thermal insulator partition configured to be removably securable to a second side of the container, a third thermal insulator partition configured to be removably securable to a top face of the container, and a fourth thermal insulator partition configured to be removably securable to a bottom face of the container.
