1. A refillable pouch reservoir for a pressurized dispensing casing, said pouch reservoir comprising a single part dome, a valve carrying cup and a pouch, wherein the single part dome comprises a base, for receiving and tight fixation of a neck of the pouch, an external surface of the base receiving an inner wall of the neck of the pouch, said base forming a tubular foot of the single part dome being comprised of a continuous wall perpendicular to a peripheral collar of the single part dome and defining a fixation surface of the neck of the pouch and a central tubular opening, wherein said single part dome further comprises a bowl to receive the valve carrying cup, said bowl comprising a bottom having an opening in continuity with the central tubular opening of the base and an outer peripheral wall provided with a projecting edge that forms a clamping bead for a collar of the cup, and an anti-collapse device for the pouch, wherein the anti-collapse device comprises a plunger element which is inserted into the pouch and a retaining plate of said anti-collapse device which is lodged in the bowl, wherein the plunger element has two distant and laterally staggered blades, and wherein the blades have complementary stop profiles adapted to oppose the blades from overlapping one another other. 2. The pouch reservoir as claimed in claim 1, wherein the external surface of the base is formed by a continuous wall against which the inner wall of the neck of the pouch is applied, the continuous wall having a circular central section and lateral tapering extensions to provide a tight gluing surface for the pouch. 3. The pouch reservoir as claimed in claim 1, wherein the retaining plate is press-fitted in the bottom of the bowl. 4. The pouch reservoir as claimed in claim 1, constituting a refill for a refillable dispensing casing. 5. A pressurized dispensing casing comprising a pouch reservoir as claimed in claim 1 and a casing body receiving the pouch of the pouch reservoir. 6. The pressurized dispensing casing as claimed in claim 5, wherein the single part dome is provided with a peripheral support collar of the dome at one edge of the body of the casing. 7. The pressurized dispensing casing as claimed in claim 6, comprising a bushing for clamping the single part dome to the body of the casing, being provided with an annular support surface which is tight against the peripheral collar of the single part dome and the edge of the body of the casing. 8. A method of production of a pouch reservoir as claimed in claim 1, wherein it involves a step of gluing or welding of the pouch to an external surface of a base beneath the single part dome, a step of filling the pouch assembled to the single part dome with the product to be dispensed, anda step of putting the valve carrying cup in place on the dome with the filled pouch. 9. The method of production of a pouch reservoir as claimed in claim 8, wherein the single part dome serves as a holding element for the reservoir during the filling of the pouch. 10. The method of production of a pouch reservoir as claimed in claim 8, wherein the valve carrying cup is crimped on the single part dome at a station of a pouch filling machine after said filling occurs.
