Abstract
The invention relates to a method for inverting the diaphragm of a filled and capped container. According to the invention, the container is placed on a support ring of an inversion device, a pressing member is applied to the container and a pusher is raised through the support ring to invert the diaphragm and shape the diaphragm into an arch. While the pusher inverts the diaphragm, the seat is moved away from the upper plane of the support ring, so that when the pusher reaches the raised position, a space is opened between the seat and the support ring to enable a longitudinal expansion of the container under the combined effect of the increase in internal pressure caused by the decrease in the volume due to the inversion and the forces generated inside the container by the pusher and the support member.
