The system according to claim 1, wherein said antireflux one-way valve comprises a compartment housing a sealing body, the sealing body being slidably movable between a sealing position when the container is in the resting position, and an opening position when the container is in the delivering condition. 15. The system according to claim 14, wherein said sealing body is adapted to engage, when in the sealing position, a airtight closure seat placed at a base of said compartment, and to detach from said seat when in the opening position. 16. The system according to claim 15, wherein said first duct intercepts said compartment in a raised position with respect to said airtight closure seat, when the container is in the resting condition. 17. The system according to claim 14, wherein said sealing body is spherical. 18. The system according to claim 1, wherein said connecting manifold comprises an external ledge. 19. The system according to claim 18, wherein said ledge extends along an entire peripheral development of said connecting manifold. 20. The system according to claim 1, wherein said through seat comprises an internal end projection. 21. The system according to claim 20, wherein said ledge is adapted to cooperate with said end projection to keep said connecting manifold in said sealing stop position. 22. The system according to claim 1, wherein said case comprises at least one slot on a side wall thereof. 23. The system according to claim 22, wherein said second duct communicates with said volume internal to the container at a second mouth located on said device at said portion internal to said through seat such that, when the device is connected with said connecting manifold in a stop position, said second mouth is adapted to receive, in a delivery phase, said consumer fluid flowing through said at least one slot. 24. The system according to claim 23, wherein said mouth is located at a periphery of said internal portion. 25.
