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 sidewall portion may generally be in an hourglass shape and employ a plurality of arched contour ribs and a plurality of arched contour lands that may alternate along a longitudinal length of the sidewall portion. An outside diameter of an upper body portion is greater than an outside diameter of a lower body portion, which may form a hand grip area. The arched contour ribs may further employ an upper flat wall, a lower flat wall, and an inner curved wall joining the upper and lower walls, which together may form an angle of about 60 degrees, and move in response to hot-fill product contraction within the container or top load forces.
