The present disclosure provides a container and a method of making a container. In one example, the container includes an upper portion having a finish defining a longitudinal axis and an opening into the container. A shoulder region is integrally formed with and extends from the upper portion. A sidewall portion extends from the shoulder region to a base portion. A tamper evident (TE) band is formed on the finish and defines an outermost surface of the plastic container above the shoulder region. A neck defining a cylindrical sidewall is integrally formed with and extends between the finish and the shoulder region. The neck defines a uniform cylindrical sidewall along its entire height between the finish and the shoulder region. The container further includes a debossed support flange defined on the upper portion. The debossed support flange defines a diameter less than a diameter defined by the TE band.
