Abstract

Package having a flexible inner sheet, a flexible secondary inner sheet, a flexible secondary outer sheet, and an outer sheet. The inner sheet and secondary inner sheet are joined together at least an outer seam and forming one or more primary expansion chambers. The package also has a flexible secondary outer sheet and an outer sheet, joined together at least an outer seam and forming one or more secondary expansion chambers. The secondary outer sheet and the outer sheet also form one or more non-expansion chambers that can be a label surface.

First claim

What is claimed is:

1. A package for one or more articles, the package comprising an article reservoir, a top panel having a top surface and a bottom panel having a bottom surface, and an outer seam, wherein each of the top panel and the bottom panel comprises:
a flexible inner sheet and a flexible secondary inner sheet, the inner sheet and secondary inner sheet joined together at the outer seam and forming one or more primary expansion chambers adapted to receive a primary expansion material; and
a flexible secondary outer sheet and an outer sheet, the secondary outer sheet and the outer sheet joined together and joined to the inner sheet and secondary inner sheet at the outer seam, and forming one or more secondary expansion chambers adapted to receive a secondary expansion material, and one or more non-expansion chambers;
wherein the one or more non-expansion chambers are provided on the top surface over the one or more primary expansion chambers.

2. The package of claim 1 , wherein the one or more non-expansion chambers is a label surface.

3. The package of claim 2 , wherein the one or more non-expansion chambers are provided in between the one or more secondary expansion chambers.

4. The package of claim 1 , wherein the one or more secondary expansion chambers are provided along two or more sides of the top surface of the package.

5. The package of claim 4 , wherein the one or more secondary expansion chambers form a frame around the perimeter of the top surface of the package.

6. The package of claim 5 , wherein the one or more non-expansion chambers are provided in the region within the frame.

7. The package of claim 1 , wherein the package has one or more expansion ports and the one or more primary expansion chambers and one or more secondary expansion chambers are in fluid communication with the one or more expansion ports.

8. The package of claim 1 , further including an article retrieval feature that allows a user to open the package and retrieve the one or more articles from the article reservoir.

9. The package of claim 8 , wherein the article retrieval feature, when activated, both opens the package and deflates the one or more primary expansion chambers and the one or more secondary expansion chambers.

10. The package of claim 1 , wherein the package consists of or consists essentially of a flexible material.

11. The package of claim 1 , wherein the primary expansion material and the secondary expansion material are air.

12. The package of claim 11 , wherein the one or more secondary expansion chambers have an air pressure that is higher than the one or more primary expansion chambers air pressure.

13. The package of claim 12 , wherein the one or more secondary expansion chambers air pressure is from 3 psig to 10 psig higher than the one or more primary expansion chambers air pressure.

14. The package of claim 12 , wherein the one or more secondary expansion chambers air pressure and the one or more primary expansion chambers air pressure is higher than ambient pressure.

15. The package of claim 11 , wherein the one or more non-expansion chambers is a label surface.

16. The package of claim 11 , wherein one or more of the primary expansion chambers are adapted to contact the article.
