Abstract

A shipping package having a flexible inner sheet having a first surface and a second surface. The package has an article reservoir for accepting an article to be shipped and one or more expansion chambers. The expansion chambers can be inflated or otherwise expanded to provide structure to the package and to protect the article in the article reservoir.

First claim

What is claimed is:

1. An expandable shipping package for shipping one or more articles having a controlled post-expansion shape, the package comprising:
a. a flexible inner sheet having an inner sheet first portion, an inner sheet second portion, an inner sheet first surface, an inner sheet second surface;
b. a flexible outer sheet having an outer sheet first portion, an outer sheet second portion, an inner surface and an outer surface, at least a portion of the inner surface of the outer sheet first portion being joined to the first surface of the inner sheet first portion to form one or more first primary expansion chambers therebetween, and at least a part of the inner surface of the outer sheet second portion being joined to the first surface of the inner sheet second portion to form one or more second primary expansion chambers therebetween; at least a portion of the second surface of the inner sheet first portion disposed in face-to-face relationship with and joined to a portion of the second surface of the second portion of the inner sheet forming an article reservoir therebetween, the article reservoir having a periphery where the inner sheet first portion and the inner sheet second portion are joined together and a central area within the periphery, wherein at least a portion of the inner sheet first surface within the central area is joined to the inner surface of the outer sheet forming an expansion control tack that acts to control the expansion of the one or more first primary expansion chambers when an expansion fluid is introduced therein;
c. a flexible secondary outer sheet at least partially joined to the outer sheet outer surface to form one or more secondary expansion chambers;
d. an expansion port in fluid connection with the one or more primary expansion chambers and/or secondary expansion chambers through which an expansion material can be introduced into the one or more primary expansion chambers and/or secondary expansion chambers; and
e. a closeable opening into which the one or more articles may be inserted, the opening extending from an exterior of the package to the article reservoir;

the package having a shape that is parallelepiped when expanded for use, the package having a top surface, a bottom surface opposed and parallel to the top surface, a first end surface extending between the top surface and the bottom surface, a second end surface opposed and parallel to the first end surface and extending between the top surface and the bottom surface, a first side surface extending between the top surface, the bottom surface, the first end and the second end, and a second side surface opposed and parallel to the first side surface and extending between the top surface, the bottom surface, the first end and the second end.

2. The expandable shipping package of claim 1 wherein the inner sheet first portion and the inner sheet second portion are separate pieces of material joined to each other or are made from a single piece of material.

3. The expandable shipping package of claim 1 wherein the expansion control tack also joins the outer sheet to the secondary outer sheet.

4. The expandable shipping package of claim 1 wherein the one or more secondary expansion chambers include two or more secondary expansion chambers in fluid communication with each other.

5. The expandable shipping package of claim 1 wherein the package has two or more secondary expansion chambers and at least one of the secondary expansion chambers is not in fluid communication with every other secondary expansion chamber.

6. The expandable shipping package of claim 1 wherein the one or more primary expansion chambers are expanded to an internal pressure that is less than at least one of the one or more secondary expansion chambers.

7. The expandable shipping package of claim 1 wherein at least one of the one or more secondary expansion chambers is expanded to an internal pressure that is less than the internal pressure of the one or more primary expansion chambers.

8. The expandable shipping package of claim 1 wherein the one or more secondary expansion chambers that is expanded to an internal pressure that is less than the internal pressure of the one or more primary expansion chambers is disposed adjacent the central area of the article reservoir.

9. The expandable shipping package of claim 1 wherein when the one or more articles is disposed in the article reservoir and the one or more first or second primary expansion chambers is expanded, the one or more articles are at least partially immobilized in the article reservoir by the inner sheet.

10. The expandable shipping package of claim 1 wherein the shipping package consists of or consists essentially of one or more flexible materials.

11. The expandable shipping package of claim 1 , wherein the package has no structural support feature other than the primary and/or secondary expansion chambers.

12. The expandable shipping package of claim 1 additionally including a vent disposed in fluid communication with the article reservoir.

13. The expandable shipping 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.

14. The expandable shipping package of claim 13 wherein the article retrieval feature, when activated, both opens the shipping package and deflates one or more of the one or more primary expansion chambers.

15. The expandable shipping package of claim 13 wherein the article retrieval feature, when activated, both opens the shipping package and deflates one or more of the one or more secondary expansion chambers.

16. The expandable shipping package of claim 13 wherein the article retrieval feature, when activated, opens the shipping package and deflates the one or more primary expansion chambers and the one or more secondary expansion chambers.

17. The expandable shipping package of claim 13 wherein the article retrieval feature includes a tear strip.

18. The expandable shipping package of claim 13 claims wherein at least one of the one or more primary expansion chambers is permanently destroyed upon activation of the article retrieval feature.

19. The expandable shipping package of claim 1 wherein at least a portion of the inner sheet, the outer sheet and/or the secondary outer sheet is transparent, translucent or opaque.

20. The expandable shipping package of claim 1 wherein the shipping package has a deflated thickness that is less than 1/10 of the expanded thickness.

21. The expandable shipping package of claim 1 wherein at least a portion of the inner sheet, the outer sheet and/or the secondary outer sheet is printed.

22. The expandable shipping package of claim 1 having at least one secondary expansion chamber disposed at least partially in the top panel and adjacent a first juncture between the top panel and the first end panel, the second end panel, the first side panel and the second side panel.

23. The expandable shipping package of claim 1 having at least one secondary expansion chamber disposed at least partially in the bottom panel and adjacent a second juncture between the bottom panel and the first end panel, the second end panel, the first side panel and the second side panel.

24. The expandable shipping package of claim 1 wherein at least one expansion control tack is disposed inwardly of the at least one secondary expansion chamber dis
