A container having a base, with a bottom surface, a first support tube fixed to the base at a first level below and substantially parallel to the bottom surface of the base; a second support tube fixed to the base at the first level below and substantially parallel to the bottom surface of the base, and spaced apart from, substantially parallel to the first support tube; a third support tube fixed to the base, at a second level below and substantially parallel to the bottom surface, and below and substantially parallel to the first level; and a fourth support tube fixed to the base, at the second level below and substantially parallel to the bottom surface of the base, and spaced apart from, and substantially parallel to the third support tube. The first and second support tubes may be substantially perpendicular to the third and fourth support tubes. |
