Abstract

A temperature insulated packaging system includes a container having interior surface bounding an interior volume and a liner disposed within the interior volume and at least partially bounding a compartment configured to receive an item for temperature insulated shipping. The liner includes a first sleeve made of cellulose material and at least partially bounds a channel. The first sleeve has an outside wall disposed adjacent to the container and an opposing inside wall disposed adjacent to the compartment configured to receive the item for shipping, the channel being disposed between the inside wall and the outside wall. At least one insulation sheet is disposed within the channel of the first sleeve, the at least one insulation sheet being made of a cellulose material and having a plurality of recesses formed thereon.

First claim

What is claimed is:

1. A method for packaging an item for insulated shipping, the method comprising:
positioning a liner along an interior surface of a container so that the liner at least partially bounds a compartment within the container, the liner comprising:
a first sleeve comprised of a first cellulose material and at least partially bounding a channel, the first sleeve having an outside wall disposed toward the container and an opposing inside wall disposed toward the compartment when positioned within the container, the channel being disposed between the inside wall and the outside wall;
a second sleeve comprised of cellulose material and at least partially bounding a channel, the second sleeve being separate and discrete from the first sleeve and being positioned so that the compartment is at least partially disposed between the first sleeve and the second sleeve, wherein the second sleeve is positioned within the container and sit on the top surface of the first sleeve;
a third sleeve, comprised of the first cellulose material and at least bounding the channel, the third sleeve being separate and discrete from the first sleeve and the second sleeve, the channel being disposed between the inside wall and the outside wall, wherein the third sleeve is positioned on top of the second sleeve to cover the compartment; and
at least one insulation sheet disposed within the channel of the first sleeve, the second sleeve, and the third sleeve, the at least one insulation sheet being comprised of a second cellulose material and having a plurality of recesses formed thereon;

disposing a cold source within the container; and
disposing an item for shipping within the compartment within the container,
wherein the liner insulates the item for shipping during shipping.

2. The method as recited in claim 1 , wherein the liner is removably disposed within the container.

3. The method as recited in claim 1 , wherein the first sleeve has a U-shaped configuration when positioned within the container.

4. The method as recited in claim 1 ,
wherein the second sleeve has a U-shaped configuration when positioned within the container.

5. The method as recited in claim 1 , further comprising inserting a locking tab projecting from the second sleeve into a locking slot formed on the second sleeve to couple the second sleeve to the first sleeve.

6. The method as recited in claim 1 , wherein the item for shipping comprises a biological material.

7. The method as recited in claim 1 , wherein the first sleeve comprises a folded sheet of paperboard.

8. The method as recited in claim 7 , wherein the sheet of paperboard is more rigid than the at least one insulation sheet.

9. The method as recited in claim 7 , wherein the sheet of paperboard is less rigid than the at least one insulation sheet.

10. The method as recited in claim 1 , wherein the channel of the first sleeve has a rectangular transverse cross section.

11. The method as recited in claim 1 , wherein the at least one insulation sheet comprises a plurality of separate sheets of paper that are stacked together, each of the plurality of separate sheets of paper being comprised of a cellulose material and having a plurality of recesses formed thereon.

12. The method as recited in claim 11 , wherein the stacked plurality of separate sheets of paper are folded.

13. The method as recited in claim 11 , wherein the plurality of separate sheets of paper comprises at least 3, 5, 10, 15, 20, 25, or 30 sheets of paper.

14. The method as recited in claim 1 , wherein the at least one insulation sheet comprises a sheet of embossed cellulose wadding.

15. The method as recited in claim 1 , wherein the container comprises a cardboard box.

16. The method as recited in claim 1 , wherein the cold source comprises dry ice.

17. The method as recited in claim 1 , wherein the cold source comprises at least one frozen gel pack.

18. The method as recited in claim 1 , wherein the liner has an insulation rating (R Value) of in a range between about 3.5/inch to about 4.5/inch measured at a mean temperature of 75° F.
