Abstract: A self aligning stacking ring guides stacked cans into alignment. The self aligning stacking ring includes radially protruding alignment bumps angularly spaced apart at a common radius corresponding to a recess in the bottom of common cans. The self aligning stacking ring guides tend to center a can placed over the self aligning stacking ring guides to make stacking cans easier and quicker.
