A base of a container may include a standing surface, a first wall, a second wall, a first hinge, and a second hinge. The first hinge may be positioned between the standing surface and the first wall, the first wall being rotateable about the first hinge relative to a longitudinal axis of the container. The second hinge may be positioned between the first wall and the second wall, the second wall being rotateable about the second hinge relative to the longitudinal axis of the container, where rigidity of the base prevents substantial net distortion of the base during rotation of the second wall.

What is claimed is: 1. A method comprising: blow molding a container, a base of the container having a first hinge, a first wall coupled to said first hinge, a second hinge directly coupled to said first wall, and a second wall coupled to said second hinge, both of said first wall and said second w
What is claimed is: 1. A method comprising: blow molding a container, a base of the container having a first hinge, a first wall coupled to said first hinge, a second hinge directly coupled to said first wall, and a second wall coupled to said second hinge, both of said first wall and said second wall being formed extending away from an interior of said container relative to a longitudinal axis of said container; inverting said first wall about said first hinge toward the interior of said container relative to the longitudinal axis; and after said inverting said first wall, inverting said second wall about said second hinge toward the interior of said container relative to the longitudinal axis, wherein rigidity of said base prevents substantial net distortion of said base during inversion of said second wall, and wherein said inverting said first wall is performed prior to filling the container. 2. The method of claim 1, wherein an air cylinder or a mechanical device inverts said first wall about said first hinge. 3. The method of claim 1, wherein an air cylinder or a mechanical device inverts said second wall about said second hinge. 4. The method of claim 1, wherein said inverting said first wall results in said first hinge, said first wall, said second hinge, and said second wall being at or above a standing surface of the container. 5. The method of claim 1, further comprising: hot-filling, capping, and cooling the container after said inverting said first wall and before said inverting said second wall, wherein said inverting said second wall alleviates a vacuum in the container. 6. The method of claim 5, where the vacuum is partially alleviated. 7. The method of claim 1, wherein the container has a sidewall with one or more vacuum panels. 8. The method of claim 1, wherein said inverting said second wall about said second hinge occurs prior to hot-filling. 9. The method of claim 1, wherein, as a result of said inverting said first wall about said first hinge, a portion of said second wall is at a standing surface of the container. 10. A method comprising: blow molding a container in a first stage, a base of the container having a first hinge, a first wall coupled to said first hinge, a second hinge directly coupled to said first wall, and a second wall coupled to said second hinge, both of said first wall and said second wall being formed extending away from an interior of said container relative to a longitudinal axis of said container; inverting, in a second stage, said first wall about said first hinge toward the interior of said container relative to the longitudinal axis; and after said inverting in said second stage, inverting, in a third stage, said second wall about said second hinge toward the interior of said container relative to the longitudinal axis, wherein rigidity of said base prevents substantial net distortion of said base during inversion of said second wall, wherein said second stage is performed prior to hot-filling the container, and wherein said third stage is performed after hot-filling, capping, and cooling the container. 11. The method of claim 10, wherein said base further comprises: a third hinge coupled to said second wall; and a section coupled to said third hinge, wherein said section rotates about said third hinge during inversion of said second wall during said third stage. 12. The method of claim 10, wherein, at the end of said second stage, said first hinge, said first wall, said second hinge, and said second wall are at or above a standing surface of the container. 13. The method of claim 10, wherein said inverting said second wall reduces a vacuum in the container. 14. The method of claim 13, where the vacuum is partially reduced. 15. The method of claim 10, wherein the container has a sidewall with one or more vacuum panels. 16. The method of claim 10, wherein the container has a sidewall free of vacuum panels or other support structure. 17. The method of claim 10, wherein, as a result of said inverting said first wall about said first hinge, a portion of said second wall is at a standing surface of the container. 18. A method comprising: blow molding a container, a base of the container having a first hinge, a first wall coupled to said first hinge, a second hinge coupled to said first wall, and a second wall coupled to said second hinge, both of said first wall and said second wall being formed extending away from an interior of said container relative to a longitudinal axis of said container; inverting said first wall about said first hinge toward the interior of said container relative to the longitudinal axis; and inverting said second wall about said second hinge toward the interior of said container relative to the longitudinal axis, wherein rigidity of said base prevents substantial net distortion of said base during inversion of said second wall, wherein said base further comprises: a third hinge coupled to said second wall; and a section coupled to said third hinge, wherein said section rotates about said third hinge during inversion of said second wall.
