The invention concerns a process for the production and packaging of a bag-type dispenser comprising a casing surmounted by a dome, a sealed flexible bag fixed in said casing and dispensing means sealingly connected to said dome and to said bag characterized in that, prior to any other assembly and packaging operation, a dome of plastics material is produced by moulding, the dome comprising an internal tubular portion permitting sealing fixing thereon on to the upper end of a skirt forming the blank for the bag, and then said fixing is produced, thus providing a preassembled component, dome+skirt, the dome further comprising portions for fixing thereof respectively on to the upper end of the casing and to the dispensing means. The invention also concerns the resulting sub-assemblies and bag-type dispensers. The invention is used in the pharmaceutical, cosmetological, hygiene and foodstuff fields.
