Abstract: A bottle includes a mouth and a neck adjoining the mouth. The neck has helical ribs on the outside to permit application of a peripherally indented, screw-on crown. The main body of the bottle has a base, which is provided with an upward recess. A plurality of inwardly projecting ribs is provided around the periphery of the recess, each rib being convexly rounded and devoid of points, and having two concavely rounded shoulder portions on either side, so that stress concentration is minimized. The recess is sized to receive a peripherally indented crown of the same size as that receivable on the neck, so that the ribs register in at least some of the peripheral indentations. Thus, one bottle can serve as a crown remover for another, without a significant risk that the ribs will break or crack.
