A seamless aluminum container of the type used for beer, soft drinks, edible goods or the like is provided which container is adapted to be manually axially collapsed to a smaller size when its contents are exhausted, the container collapse being accomplished without the need of any apparatus for guiding the container sidewall collapse and without the aid of any mechanical or fluid pressure device. The container sidewall is shaped to provide a number of similar annuli each of concave axial cross section, adjacent annuli being separated by a peripheral, outwardly angled ridge. Manual axial forces collapse adjacent about an interposed ridge to form a collapsed container approximately one-fifth the size of the original container. The device encourages consumers to recycle aluminum, facilitates the storage and transport of aluminum cans to a recycling station, strengthens aluminum cans in a transverse direction permitting thinner aluminum stock to be used, and conserves aluminum and the energy needed to produce aluminum.
