Beverage container with improved bottom strength.

摘要

A container with improved strength includes a cylindrical sidewall (12) that is disposed around a vertical axis, and a bottom (66). The bottom of the container provides a supporting surface (18) and includes a bottom recess portion (68) that is disposed radially inwardly of the supporting surface (18). The bottom recess portion includes a center panel (38), and a dome positioning portion (70) that positions the center panel above the supporting surface. The dome positioning (70) portion includes a first part (22) that is disposed at a first radial distance from the vertical axis and an adjacent part (98) that is disposed at a different radial distance from the vertical axis. In the container, a plurality of the adjacent parts are arcuately disposed are circumferentially spaced around the dome positioning portion and are interspersed with a plurality of the first parts. In the container the adjacent part is disposed circumferentially around the dome positioning portion at one height from the supporting surface, and the first part is disposed circumferentially around the dome positioning portion at a different height from the supporting surface.
