A double coupler nozzle system for sealing to a pair of flexible film bags (or to a double bag, i.e. three triangles of film welded down the diagonals or a single piping bag which has been welded down the length) having a wider upper end and a conical lower end with an opening for flowable material inside the bag and for expressing the flowable material. The system comprises a pair of hollow nozzle bases (20a, 2b) each having an exterior wall and an interior wall (35a, 35b, 36a, 36b) and being coupled together along the interior walls (35a, 35b, 36a, 36b). The exterior wall of each nozzle base form a portion of a substantially right circular truncated cone with a larger diameter end (42) and a smaller diameter end (44) and cut along a plane containing the longitudinal axis of the cone, the interior wall (35a, 35b, 36a, 36b) of each nozzle base being non-planar and spanning edges of the exterior wall to form an inlet opening adjacent the nozzle base larger diameter end (42) and an outlet opening adjacent the nozzle base smaller diameter end (44), the nozzle base interior walls (35a, 35b) extending inward or outward, or male/female, and complimenting each other when the bases are coupled together along the interior walls. Each of the nozzle bases (20a, 20b) are adapted to be received snugly within the conical lower end of one of the bags with the film of the lower end of the bag extending over the exterior and interior walls of the nozzle bases and having a lower bag edge ending intermediate the larger (42) and smaller diameter ends (44) of the nozzle base (20a, 20b), and having film of the bags between the respective interior walls of the coupled nozzle bases (20a, 20b). The coupled nozzle bases permit side-by-side simultaneous flow of material from bags sealed to the nozzle bases and out of the outlets of the coupled nozzle bases.Linvention concerne un système dembout à double raccord destiné à être amené en contact détanchéité avec une paire de poches formées dun f
