The invention relates to a leaktight container (1) having a flexible wall comprising a bag (2) formed from a flexible film arranged so as to define a leaktight interior volume and a through-opening, and means for fixing the bag (2) to a connecting device (4) for connecting the container (1) in a leaktight manner to a sterile enclosure equipped with a complementary connecting device (4), said fixing means comprising a fixing ring (6) arranged so as to allow the connecting device (4) to be fixed reversibly to the bag (2), said ring being made up of two concentric annular parts fitted one in the other, the external annular part being dimensioned so as to be force-fitted around the internal annular part and to exert a radial stress thereon, the portion of film delimiting the through-opening being gripped between the two annular parts.
Leaktight container (1) having a flexible wall comprising a bag (2) formed from a flexible plastics film arranged so as to define a leaktight interior volume and comprising a through-opening, and means for fixing the bag (2) to a connecting device (4) which allows for leaktight connection of the container (1) to a sterile enclosure equipped with a complementary connecting device (4), characterized in that the fixing means comprise a fixing ring (6) arranged so as to allow the connecting device (4) to be fixed reversibly to said bag (2), said fixing ring (6) being made up of two concentric annular parts fitted one in the other in order to define, respectively, an internal annular part (7) and an external annular part (8), the external annular part (8) being dimensioned so as to be force-fitted around the internal annular part (7) and to exert a radial stress thereon, the portion of film (20) delimiting the through-opening being gripped between the external annular part (8) and the internal annular part (7).
Leaktight container (1) having a flexible wall according to any of the preceding claims, characterized in that the knurls (10) of the internal annular part (7) are spaced apart from one another so as to define a contact zone for contact with the internal face of the external annular part (8) and delimited by the knurls (10), which zone is subjected to a lower pressure stress than that exerted by said knurls (10) on the external annular part (8).
Leaktight container (1) having a flexible wall according to any of the preceding claims, characterized in that the internal annular part (7) is of a height that is greater than that of the external annular part (6).
Leaktight container (1) having a flexible wall according to any of the preceding claims, characterized in that the connecting device (4) is borne by the internal annular part (7).
Leaktight container (1) having a flexible wall according to any of the preceding claims, characterized in that the external annular part (8) is clip-mounted on the internal annular part (7).
Leaktight container (1) having a flexible wall according to any of the preceding claims, characterized in that the fixing ring (6) is made of a bacteriostatic plastics material.
Leaktight container (1) having a flexible wall according to any of the preceding claims, characterized in that it comprises a connecting device (4) which is arranged so as to connect the container (1), in a leaktight manner, to a sterile enclosure equipped with a complementary connecting device, ensuring sterile communication between the interior volume of said container (1) and that of the enclosure, the connecting device (4) comprising a flange which is fixed in a reversible and leaktight manner to the fixing ring (6), and delimiting, together with said fixing ring, the through-opening.
Leaktight container (1) having a flexible wall according to any of the preceding claims, characterized in that the fixing ring can be dismantled.
