They are composed of: A transparent Plexiglass cylindrical container into which the water is poured and the vacuum is created. A mobile transparent Plexiglass lid with, on its lower part, a perforated disc fixed via a pin which is for keeping the flow pack wrapping submerged in the water, in the container and on
