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.
