Plastic container base structure and method for hot filling a plastic container |
摘要 |
A base for a plastic container defining a central longitudinal axis. The base includes an annular standing ring portion defining a standing surface. The base includes a substantially cylindrical ring portion extending in a direction substantially perpendicular to the standing surface. The base further includes a substantially concave dome portion extending inwardly from the substantially cylindrical ring portion to the longitudinal axis. The concave dome portion of the base includes a first plurality of substantially triangular panels circumferentially spaced around the longitudinal axis, and a second plurality of substantially triangular panels circumferentially spaced around the longitudinal axis. At least a portion of each of the second plurality of substantially triangular panels is circumferentially and longitudinally offset from the first plurality of substantially triangular panels. A container preform and method of hot filling a plastic container are also disclosed. |
