Carousel machine for a treatment station

A method for creating a vacuum in a container that is to be treated by a carousel machine, the method comprising at least the following steps:

• placing the container in a treatment station of the carousel machine, an internal volume of the container and a volume of an included pipe extending between the internal volume and an airtight rotary coupling forming one evacuation volume of said treatment station;
• placing the evacuation volume in fluidic communication with an associated pipe associated with a first pressure source from among a plurality of pressure sources for a first predetermined duration that is less than or equal to a time taken for equilibrium between a pressure in the evacuation volume and a pressure in said associated pipe to become established, the pressure in the evacuation volume decreasing down to a first reduced pressure during said first predetermined duration;
• and
• placing the evacuation volume at the first reduced pressure in fluidic communication with an associated pipe associated with a second pressure source from among the plurality of pressure sources for a second predetermined duration, the pressure in the evacuation volume decreasing, from the first reduced pressure to a second reduced pressure that is lower than the first reduced pressure, during said second predetermined duration.
