Abstract: A plastic bottle is disclosed, which comprises a cylindrical sidewall having a predetermined thickness, an upper mouth-forming portion, a neck extending from this mouth-forming portion, a dome-shaped portion between the neck and one axial end of the cylindrical sidewall, a lower bottom-forming base extending from the other axial end of the cylindrical wall, all about a central axis. The bottle also has at least three substantially vertical exterior ribs that are substantially uniformly angularly spaced from each other about the axis on the neck, and these ribs have maximum cross-sectional radial dimensions along the axis generally greater than said predetermined thickness. The ribs reinforced the neck and distribute forces resulting from impact of a localized force to the mouth-forming portion towards the dome-shaped portion and cylindrical sidewall.
