Abstract: Some embodiments relate to a metering device, including: a metering chamber; a piston separating the metering chamber into a supply compartment and a metering compartment, the piston including a passage between the two compartments; a valve for closing the passage, allowing the passage of the product when same is in the open position; and movement mechanisms of the valve. The valve includes drive mechanisms of the piston arranged on either side of the piston in such a way that the movement of the valve in a discharge direction drives the movement of the piston in the discharge direction and the movement of the valve along the length of the cylinder body in a transfer direction, and drives the movement of the piston.

Abstract: A method for processing containers includes, for each container to be processed: a) an assembling step of assembling a cap having a cover on a container, the cap including a tubular base and a cover pivotably connected to the base, between an open position and a closed position, the cap being assembled via the base thereof onto the container at an opening of the container, b) a step of sterilizing the container provided with the cap having a cover, and c) a step of filling the container, the filling step including filling the container with a filling product while the cap having the cover is in the open position, and moving the cover into the closed position.

Abstract: A treatment device for sterilizing containers by an electron beam includes a carousel that comprises a rotary holding plate supporting a plurality of treatment stations, each station including a sterilization device comprising an electron beam emitter, and a holding device for holding a container under the emitter. The treatment device includes a protection system for stopping the rays emitted by the emitters, the protection system comprises an annular segment-shaped, open stationary channel that is mounted in a stationary manner under the holding plate and forms, with the latter, a protective chamber in which the holding device supporting the containers moves, the channel having an open upstream end, for the inlet of the containers to be treated into the protective chamber, and an open downstream end, for the outlet of the treated containers from the chamber.

Abstract: A treatment device includes one or more treatment stations each including an electron-beam emitter and supporting device for supporting a container beneath the emitter, the emitter being capable of emitting an electron beam passing through the upper opening of a container supported by the supporting means, so as to sterilize the container, and a protection system for stopping the radiation emitted by the emitter(s). The protection system includes an upper portion connected to the emitter, lower portion connected to the supporting device and a moving device capable of moving the upper portion relative to the lower portion, between a retracted position and at least one operative position in which the portions from a protective enclosure in which the emitter and container are positioned.

Abstract: A method for manufacturing sterile flexible bags filled with a filling product and provided with a valve, including a) a step of placing valves on a first flexible film and sterilizing at least one of the two surfaces of the first film, b) a step of forming bags by heat welding from at least the first film, and filling the bags with a filling product. The valves each include a base applied directly onto the first film, and a tube assembled via an open end onto base in order to cover a tapping area of the base, the tube having a removable portion intended to be removed to uncover the tapping area and allow the product to be withdrawn by poking a needle into the area.
