FIELD: technological processes.
SUBSTANCE: invention discloses the device (1), which consists of discharge tube with cylindrical side wall, internal thread (21) and end flange (22) and adapter screwed into discharge tube. Adapter has inlet end with external thread (32) and output end (31) with conical tip (35) for connection of slip-on flexible tube. At the bottom in the direction of screwing edge adapter there is at least one dual-purpose perforating and cutting tooth (34). A special seal between a sleeved bag (4) and adapter is provided to achieve maximum sealing force. For this purpose cylindrical side wall of the discharge tube is made passing over the end flange (22) to double-walled section. Its outer part is formed by radially outward inclined conical sustaining wall (24), and the inner part of double-walled section is formed by the sealing apron made slightly conical but directed radially inside.
EFFECT: ruled out ingress of fluid between discharge tube and adapter connected with thread in view of tendency to liquid penetration in between under certain conditions due to breach of the sleeved bag film.
