A plastic blow molded water bottle of a round shape having a central axis and comprising:

• a generally cylindrical body portion having upper and lower ends, the body portion having an upper label panel that extends inwardly to provide label protection, and the body portion including a plurality of lower strengthening rings below the label panel;
• an upper dispensing end having a shoulder extending upwardly and inwardly from the upper end of the body portion with a curvature in an elevational direction with a maximum radius that is less than one-half of the maximum diameter of the bottle, and the upper dispensing end having a dispensing spout extending upwardly from the shoulder;
• and
• a lower base having a side wall extending downwardly and inwardly from the lower end of the body portion, a lower annular support extending inwardly from the side wall to support the bottle in an upstanding manner on a horizontal support surface, a dome extending upwardly and inwardly from the lower annular support, the maximum diameter of the lower base being about eight times the height of the dome above the support surface at the central axis, the dome including an outer annular wall extending generally vertically, a dome portion extending upwardly and inwardly from the outer annular wall with a downwardly concave curved shape, strengthening ribs that extend outwardly in a radial direction from the central axis on the dome portion and have cross sections that project downwardly with an upwardly opening shape, the strengthening ribs having radial inner ends that converge inwardly with pointed shapes and radial outer ends of a uniform cross section, and connections between the outer ends of the strengthening ribs and the outer annular wall.
