An apparatus for the containment of objects includes a container having at least one expandable portion that includes an expandable surface and a plurality of elastomers connected to the container and to the expandable portion that normally supplies a force to the expandable surface to retract it toward the container. When the objects exceed the normal volume in the container and the container is closed, the elastomers expand where needed and to a minimum extent as needed sufficient to accommodate the objects. When the objects do not exceed the normal volume and the container is closed, the elastomers automatically retract the expandable portion into a retracted position.
