Abstract: The invention relates to a bag for sealingly packaging components, which includes: a flexible body (10) defining an inside space, including a communication opening and a side wall including a plurality of strips folded against one another; and a joining device which can selectively open or close the communication opening, and is shaped so as to be mounted on an enclosure to allow sealed communication between an inner cavity of the enclosure and the inside space of the bag, the bag being characterized in that at least one fold made up of two strips opposite one another is detachably connected to at least one other fold.

Abstract: A temporary sealed double-door junction device, for temporarily communicating a controlled-environment chamber with a controlled-environment removable container having a flexible wall, includes a female flange normally blocked by a female door, forming an assembly for the chamber, and a male flange normally blocked by a male door, forming an assembly for the container, wherein the male flange is to be sealingly coupled to the female flange, and the male door is to be sealingly coupled to the female door and to pass through the female flange. A shaft passes through the male door at a central portion thereof, wherein, on the side of the surface to be joined with the female door, an impeller having at least two blades is mounted by rigid attachment onto the shaft, and on the side of the opposite surface, a crank having at least two arms is mounted by rigid attachment onto the shaft.
