Abstract:
Leaktight confinement appliance (1), intended to cooperate with a first independent receptacle (5) containing a substance (6), having a first transfer means (12) for transferring the substance into and out of the first receptacle, and a second independent receptacle (3) containing another substance (4), having a second transfer means (8) for transferring the other substance into and out of the second receptacle (3), and with at least one independent means (71) for delivery of a material, said appliance (1) comprising:a handling chamber (2) defined by a wall (13) of flexible material substantially leaktight with respect to the external environment; a means for leaktight assembly (60) between said handling chamber (2) and the first transfer means (12) of the first receptacle (5) with the first receptacle (5) remaining essentially outside said handling chamber, and this means occupying a passage (14b) through said wall (13) of said handling chamber and being secured in a leaktight manner on said wall; a means for leaktight assembly (50) between said handling chamber (2) and the second transfer means (8) of the second receptacle (3) with the second receptacle remaining essentially outside said handling chamber (2), and this means occupying another passage (14a) through said wall of said handling chamber and being secured in a leaktight manner on said wall, whereby the first transfer means (12) selectively connects to the second transfer means (8) by at least partially collapsing said handling chamber for introducing the substance of the first receptacle (5) to the other substance of the second receptacle (3); and a means (70) for leaktight connection between said handling chamber (2) and the delivery means (71) with the delivery means including a part outside said handling chamber, and this leaktight connection means occupying another passage (14c) through said wall (13) of said handling chamber and being secured in a leaktight manner on said wall, whereby the material may be delivered from within said handling chamber through said delivery means (71).
