A one-piece plastic hot-fill container may employ a shoulder portion, a base portion and a sidewall portion, which may be integrally formed with and extend from the shoulder portion to the base portion. The container may further employ a plurality of compression ribs molded into the sidewall portion—a first of the plurality of compression ribs intersecting a second of the plurality of compression ribs to form a rib interface, at least the first and the second of the plurality of compression ribs changing from a first shape to a second shape in response to cooling of the liquid.
