Abstract
A blow molded, thin walled plastic container for filling with a liquid whose temperature is elevated above ambient. The container includes a first portion of a first diameter, a second portion of a second diameter, and reduced diameter region between the first and second portions. The reduced diameter portion extends circumferentially around the container and a plurality of ribs which are located to extend between the first and second portions. The ribs form reinforcing members in the reduced diameter portion and increase the top load capabilities of the container. The first and second portions can both be formed in the shoulder portion of the container or one in the shoulder portion and one in the sidewall of the container.
