Provided is a container that includes a top having an opening configured to receive a product. The container also includes a bottom adjoining a sidewall that extends to the top of the container and a flexible panel disposed on the bottom and having a plurality of surfaces that each extend radially around a longitudinal axis of the container. One of the plurality of surfaces comprises a downward ramp that extends away from the top of the container when moving radially inward along the downward ramp and another of the surfaces comprises an upward ramp that extends toward the top of the container when moving radially inward along the upward ramp. The surfaces may include dimples protruding inward from the outer surface of the container that have an interlocking pattern.
