Abstract: The can stacker is in the form of a flexible resilient split ring of elastic memory-retaining material such as rubber or plastic, capable of being opened to accommodate the rims of cans of various diameters. The ring includes a generally vertical, annular split rim and a number of separate, spaced, generally horizontal fins adapted collectively to support a can. The fins extend radially inwardly from the rim on opposite sides of the split and are connected to the inner margin of the rim at about the vertical mid point thereof by preferably narrow stems bearing annular recesses on their upper and lower surfaces. The recesses and the rim inner surfaces form can rim-receiving grooves. The fins may be tapered inwardly to facilitate closing the rim to accommodate smaller diameter cans. The can stacker is adapted to loosely receive the rims of a pair of cans to be vertically stacked.
