Abstract
Abstract A container is disclosed having a first massive container element with side walls and bottom wall defining a first interior. The first massive container has an opening exposing the first interior. A second massive container element is provided with side walls and bottom walls cooperating to define a second interior. The second massive container element is disposed within the interior of the first massive container element with exterior walls of the second container element abutting interior walls of the first container element. A first cap is sized to cover the opening of the first container element. A second cap is provided and sized to pass through the opening of the first container element and cover the opening of the second container element. Drive pins are provided through axially aligned holes to fasten the first cap to the first container element and simultaneously urge the second cap into sealing engagement with the second container element.
