Abstract

A container-treatment method, of the type in which the container (12) is disposed inside a chamber (16) which defines a cavity (18) outside the container (12) and which is connected to a Vacuum pumping circuit (50), the interior of the container (12) being connected to the pumping circuit (50). The method includes a preliminary pumping step (E1) which is followed by a treatment step (E2). The preliminary step (E1) includes the following successive phases, namely: an external pumping phase (P1) which produces a drop in the pressure inside the cavity (18) only; and an internal pumping phase (P2) which produces a drop in the pressure inside the container (12) only. A machine used to implement the method is also disclosed.
