Abstract

Non-durable self-supporting flexible containers with easily variable sizing. Line ups of flexible containers have similar sizes, shapes, and constructions, but hold differing amounts of fluent product at unexpected fill heights.

First claim

What is claimed is:

1. A line-up of two or more flexible containers for retail sale of one or more fluent products, the line-up comprising:
a first disposable self-supporting flexible container, configured for retail sale, having a first structural support frame, a first overall front profile having a first panel, and a first product space with a first total capacity, the first panel overlaying the first product space and the first structural support frame containing one or more first expansion materials that are one or more first gases, the first structural support frame being adapted to make the first container stand upright; and
a second disposable self-supporting flexible container, configured for retail sale, having a second structural support frame, a second overall front profile that has substantially the same size and shape as the first overall front profile and having a second panel, and a second product space with a second total capacity that is a particular percentage that is between 5% and 70% less than the first total capacity, the second panel overlaying the second product space and the second structural support frame containing one or more second expansion materials that are one or more second gases, the second structural support frame being adapted to make the second container stand upright.

2. The line-up of claim 1 , wherein the particular percentage is between 10% and 60%.

3. The line-up of claim 1 , wherein the second overall front profile has the same size and shape as the first overall front profile.

4. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel with a first squeeze panel profile; and
the second container includes a second squeeze panel with a second squeeze panel profile that is substantially the same as the first squeeze panel profile.

5. The line-up of claim 4 , wherein the second squeeze panel profile is the same as the first squeeze panel profile.

6. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel;
the second container includes a second squeeze panel; and
the second squeeze panel is less extensible than the first squeeze panel.

7. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel made from one or more first flexible materials having a first overall modulus of elasticity;
the second container includes a second squeeze panel made from one or more second flexible materials having a second overall modulus of elasticity; and
the second overall modulus of elasticity is greater than the first overall modulus of elasticity.

8. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel made from one or more first flexible materials;
the second container includes a second squeeze panel made from one or more second flexible materials; and
the first flexible materials are mechanically treated to increase extensibility.

9. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel made from one or more first flexible materials;
the second container includes a second squeeze panel made from one or more second flexible materials; and
the first flexible materials are incrementally stretched.

10. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel made from one or more first flexible materials;
the second container includes a second squeeze panel made from one or more second flexible materials; and
the first flexible materials are thermally treated to increase extensibility.

11. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel made from one or more first flexible materials;
the second container includes a second squeeze panel made from one or more second flexible materials; and
the second flexible materials are chemically treated to increase rigidity.

12. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel made from one or more first flexible materials;
the second container includes a second squeeze panel made from one or more second flexible materials; and
the second flexible materials are coated to increase rigidity.

13. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel made from one or more first flexible materials;
the second container includes a second squeeze panel made from one or more second flexible materials; and
the second flexible materials are configured with one or more overlapping folds.

14. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel made from one or more first flexible materials;
the second container includes a second squeeze panel made from one or more second flexible materials; and
the second flexible materials are under more tension than the first flexible materials.

15. The line-up of claim 1 , wherein:
the first container includes a first squeeze panel that has a first side profile central depth measurement;
the second container includes a second squeeze panel that has a second side profile central depth measurement that is less than the first side profile central depth measurement.

16. The line-up of claim 1 , wherein the second container includes a second squeeze panel that has a second overall squeeze panel area and the second squeeze panel is joined to a second opposing side of the second container at one or more second joining locations within the second overall squeeze panel area.

17. The line-up of claim 1 , wherein the second container includes a second squeeze panel that has a second overall squeeze panel area and the second squeeze panel is joined to a second opposing side of the second container by one or more second internal tie members within the second overall squeeze panel area.

18. The line-up of claim 1 , wherein the second container includes a second squeeze panel that has a second overall squeeze panel area and the second squeeze panel includes one or more second expanded surface stiffening members within the second overall squeeze panel area.

19. The line-up of claim 1 , wherein:
the first container includes a first structural support frame that includes one or more first expanded structural support volumes, which are expanded with a first expansion material at a first internal expansion pressure; and
the second container includes a second structural support frame that includes one or more second expanded structural support volumes, which are expanded with a second expansion material at a second internal expansion pressure that is greater than the first internal expansion pressure.

20. The line-up of claim 1 , wherein the first container is made of a flexible material and the second container is made of a second flexible material and the flexible materials are the same.

21. The line-up of claim 1 , wherein the second total capacity of the second product space is decreased due to a negative pressure applied within the second product space.

22. The line-up of claim 19 where the first expansion material and the second expansion material are the same material.
