DEVICE FOR CONNECTING A FLEXIBLE CONTAINER TO AN EXTERNAL DUCT, AND USES THEREOF

摘要

A connecting device for connecting a container (1) consisting of a sealed flexible bag (3) to an external duct (2) that includes a tube (4) with a connecting opening (5). A rigid tubular coupling (6) is loosely arranged within the flexible container (1) and comprises a frusto-conical projection (7) sized in such a way that it may be force-fitted into the opening (5). A user grasps the coupling (6) and places it against the inner surface of the bag (3) while placing the opening (5) of the external duct (2) against the outer surface of the bag (3), then axially presses on the coupling (6) so that it perforates the bag (3) and sealingly engages the opening (5). The fluid in the container (1) can then flow through the coupling (6) into the external duct (2).
