Abstract
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.

A base of a container comprising:
- a standing surface;
- a first wall;
- a second wall;
- a first hinge positioned between said standing surface and said first wall, said first wall being rotateable about said first hinge relative to a longitudinal axis of the container;
- and
- a second hinge positioned between said first wall and said second wall, said second wall being rotateable about said second hinge relative to the longitudinal axis of the container, wherein rigidity of said base prevents substantial net distortion of said base during rotation of said second wall.
A container having a longitudinal axis comprising:
- an upper portion having an opening into an interior of the container;
- a neck portion connected to said upper portion;
- a body connected to said neck portion;
- and
- a base connected to said body, said base comprising:
- a standing surface;
- a first wall;
- a second wall, said first wall and said second wall extending away from the interior of the container relative to the longitudinal axis;
- a first hinge positioned between said standing surface and said first wall, said first wall being rotate able about said first hinge toward the interior of the container relative to the longitudinal axis;
- and
- a second hinge positioned between said first wall and said second wall, said second wall being rotateable about said second hinge toward the interior of the container relative to the longitudinal axis, wherein rigidity of said base prevents substantial net distortion of said base during inversion of said second wall.
