The invention relates to a method for shaping the bottom of hot-filled containers (1), in which the bottoms (3) of the containers are forced inward as they cool from a state (6) bulged outward, in particular during cooling. The fact that the bottoms are forced inward by at least one fluid jet (4) and/or fluid pressure wave (35) means that complicated mechanisms for forcing the bottom in are unnecessary In addition, bottom shaping can advantageously be carried out in a production area immediately following a closer.
