Plastic container with ring stabilized base

摘要

A plastic container is provided which includes a stabilizing ring attached to the base structure of a blow molded bottle for improving the vertical stability to the container when supported upon a horizontal surface. The container includes a plastic bottle having a tubular sidewall and a base structure closing the bottle at an end of the sidewall. The base structure includes an outer wall having a radially inner lower edge portion, an inner wall within the outer wall which has an axial recessed portion extending upward into the container. The lower edge portions of the inner and outer walls are merged together. The stabilizing ring is attached to the base structure and extends radially outwardly and downwardly forming an annular supporting surface at the lower edge of the ring upon which the container is supported.
