Abstract
A method of making a one-piece plastic container having a body, a raised bottom and a flange integral with the bottom and the body joining the bottom edge of the body and the periphery of the raised bottom, the flange being sealed to the lower portion of the body which surrounds the flange. The container is initially molded with a bottom integral with its body at the bottom edge of the latter, and the bottom is displaced to a raised position relative to the bottom edge of the body with accompanying formation of the flange.
