Device (10) for achieving communication, via a coupling means, between a first chamber (1) and a second chamber (2). The coupling means comprises, on the same side as the first chamber (1), a first shut-off member (41), and, on the same side as the second chamber (2), a second shut-off member (4) co
Device (10) for achieving communication, via a coupling means, between a first chamber (1) and a second chamber (2). The coupling means comprises, on the same side as the first chamber (1), a first shut-off member (41), and, on the same side as the second chamber (2), a second shut-off member (4) comprising a second flange (52) forming a seat for a second removable shutter element (72). The coupling means further comprises means of sealed connection between two flanges (51) and (52). The second chamber (2) being defined by the inside of a flexible and sealed bag (15), the border of the mouth of which is connected in a sealed way to the second flange (52). When the coupling, means is in an uncoupled position, the flexible bag (15) comprises a band (15d) extending the bag (15) continuously beyond the second flange (52), defining a closed (15f) and sealed, but openable envelope (12) for protecting the second shut-off member (42).

1. A device (10) for achieving communication, via a coupling means, between a first chamber (1) and a second chamber (2), each of which is sealed with respect to an external medium (3), maintaining the seal against the external medium of a communication passage defined between the two chambers, said coupling means comprising: on the same side as the first chamber (1), a first shut-off member (41) comprising a first flange (51) forming a seat for a first removable shutter element (71), with a sealing gasket (81) between the seat and the shutter; on the same side as the second chamber (2), a second shut-off member (42) comprising a second flange (52) forming a seat for a second removable shutter element (72), with a sealing gasket (82) between the seat and the shutter; means of sealed communication between the two flanges (51) and (52), defining a contaminable external critical line, and means for the sealed connection of the two shutter elements (71) and (72), defining a contaminable internal critical line, contiguous with the external critical line; one (2) of the chambers being defined inside of a flexible and sealed bag (15) having a closed end (15c), the border of the mouth of which is, connected in a sealed way to the second flange (52); wherein, when the coupling means is in the uncoupled position, the flexible bag (15) comprises, at the opposite end to its closed end (15c), a band (15d) extending it continuously beyond the corresponding flange (52), determining a closed (15f) and sealed, but openable envelope (12) for protecting most of the corresponding shut-off member (42) and comprising a strip (15g) connected to the corresponding flange (52) for separating the inside of the bag (15) from the inside of the protective envelope (12) in a sealed way. 2. The device as claimed in claim 1, wherein the strip (15g) of the flexible bag is held tightly against the corresponding flange (52) by a collar (90). 3. The device as claimed in claim 2, wherein the strip (15g) is shaped into a fold, determining an outer flank (15g1) and an inner flank (15g2) trapping a gasket (91) or flexible material between them. 4. The device as claimed in claim 1, wherein, on each side of the corresponding shut-off member (42), the inside of the protective envelope (12) and the inside of the bag (15) are under a partial vacuum. 5. The device as claimed in claim 1, wherein one (1) of the chambers is fixed, and the other chamber (2), defined by the inside, of the flexible bag (15) is removable to provide a use-once container. 6. The device as claimed in claim 5, wherein the flexible bag (15) comprises at least one object (14) or a charge to be transferred, when the coupling means is in the coupled position, through the communication passage from said removable chamber (2) to the fixed chamber (1). 7. The device as claimed in claim 6, wherein the flexible bag (15) is an outer bag and comprises a sealed inner flexible bag (16) separate from the outer bag (15), in which the charge or the object is placed. 8. The device as claimed in claim 7, wherein the inner flexible bag (16) is connected to the outer flexible bag (15) via its end (16b) which is the opposite end to the end which has the shut-off member (42). 9. The device as claimed in claim 7, wherein the inner flexible bag (16) comprises a sleeve (16a) forming a closure means by being folded on itself, and the outer flexible bag (15) is under partial vacuum. 10. The device as claimed in claim 9, wherein the inner flexible bag (16) is also under partial vacuum. 11. The device as claimed in claim 10, wherein the band (15d) of the flexible bag (15), has a relatively flattened shape and has a first end that connects the mouth (15a) of the bag, and a second end that defines a folded-over part (15h) pressed against the face opposite it of the second shut-off member (42).
