Abstract (en)

A plastic bottle (10) with a base (14) centered on a vertical axis (Y), a continuous standing ring (16) to support the bottle, a side wall (18) formed unitarily with the base extending from the base upward to an upper side wall end (20), and a neck (22) connected to the side wall upper end, the neck including a finish (24) adapted to receive a cap to close an opening (26) into the bottle interior. The bottle base standing ring is defined in vertical cross-section by a continuous curve bounded on a radial inside by an interior region (32) that can include a plurality of concave domed wedge-shaped sections (34) interspaced with buttress sections (36) having substantially planar inclined outer portions (38). The bottle base standing ring has a diameter (D) less than 80% of the maximum side wall width (W) and is bounded on a radial outside by a conic section portion (46) centered on the vertical axis having an apex angle of less than 160° to improve the perpendicularity of the bottle.
