Abstract: A system may include at least one multipurpose container with a bottle portion and a cap portion, and the bottle portion may include a bottle wall about the interior and forming an outer surface. The outer surface may have primary faces configured to permit vertical stacking of the container on another container in a stack of containers, and secondary faces. Alignment features may facilitate alignment of the bottle portions in a stack of containers, and at least a pair of the alignment features may be located on the primary faces. The alignment features may include at least one aligning lug located on and protruding from the first primary face and at least one aligning recess located on and depressed into the second primary face to removably receive the at least one aligning lug of a said container in the stack of containers.
