Abstract
A method for forming, in an inversion device, a base of a filled and sealed plastic container, comprising a step of inverting a diaphragm situated at the center of the base of the container and surrounded by a standing ring forming a standing surface. During the step, two opposing pushing members are set in relative motion with respect to one another so as to come into contact with and press on two longitudinally opposed regions of the container. During a phase of pushing the diaphragm during the inversion thereof, there is sought, on a curve representative of the force applied to the diaphragm to move same during the inversion, a variation on this curve that indicates whether the forces applied by the pushing members to the regions with which they are in contact are becoming smaller.
