Abstract
Abstract One of the two confined volumes, for example the "supplying" one (2), is provided with a tubular perforating element (3) confined within a space closed by a diaphragm or perforable wall (503); the second confined volume (1) also has a perforable diaphragm (301); the surfaces of the two diaphragms (503, 301) directed towards the external environment are permanently bonded together after which the perforator (3) is manipulated from the outside so as to perforate the two diaphragms, placing in communication, via the tubular duct of the perforator, the confined environment of the supplying volume with that of the second volume.
