Abstract

The invention relates to a temporary sealed double-door junction device, for temporarily communicating a controlled-environment chamber (C2) with a controlled-environment removable container (C1) having a flexible wall, comprising a female flange (3) that is normally blocked by a female door (4), forming an assembly for such a chamber, as well as a male flange (1) that is normally blocked by a male door (2), forming an assembly for such a removable sealed container, wherein said male flange is to be sealingly coupled to the female flange, and said male door is to be sealingly coupled to the female door and to pass through the female flange. A shaft (10) 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 (H2) having at least two blades is mounted by rigid attachment onto said shaft, and on the side of the opposite surface, a crank (H1) having at leasl two arms is mounted by rigid attachment onto said shaft. The female door comprises, under the surface thereof to be joined with the male door, notches (11) provided in the body of said female door for receiving the blades of the impeller (H2) while the latter is rotating, thus securing the 2 doors together. The inner section of the male flange and the outer section of the male door have complementary outlines having variations in distance relative to the shaft such that the crank has a door-locking configuration and an opening configuration.
