A cartridge (1) containing a food substance adapted to interact with water injected in the cartridge to produce a food liquid comprising: a cup (2) having a chamber for holding the food substance (10) and a lid (7), a puncturable delivery wall (8) that holds the substance in the chamber, a puncturing structure (11) to puncture at least one opening in the delivery wall as a response of water filling the chamber, a collecting area (5) for collecting the liquid passing through the delivery wall in a substantially axial direction; said collecting area being placed downstream the puncturable delivery wall (8), at least one liquid outlet (15) in the collecting area for allowing the liquid to leave the collecting area, wherein the cartridge comprises a support structure (12) comprising at least one support surface (14, 17, 18, 19) configured to support at least one portion of the delivery wall to maintain a flow gap between the puncture structure (11) and the at least one outlet (15).

1. A cartridge containing a food substance that interacts with water injected into the cartridge to produce a food liquid that is dispensed from the cartridge comprising: a cup having a chamber for holding the food substance and a lid,a puncturable delivery wall that holds the substance in the chamber,a puncturing structure comprising a series of protrusions and being adapted to puncture at least one opening in the delivery wall in response to water filling the chamber,a collecting area for collecting the liquid passing through the delivery wall in a substantially axial direction, the collecting area being located downstream of the puncturable delivery wall,at least one liquid outlet in the collecting area for allowing liquid to leave the collecting area, andat least one support surface arranged in the flow path between the puncturing structure and the at least one liquid outlet, in the collecting area at a radial distance from the at least one liquid outlet for preventing the delivery wall from collapsing in the collecting area or from forming blocking areas for the flow, wherein the at least one support surface comprises (i) portions of ridges extending in a radial direction relative to a center of the collecting area and between the protrusions, and (ii) curved portions of ridges arranged in a discontinuous concentric pattern that forms radial passages therebetween. 2. The cartridge of claim 1, wherein the support surface is further positioned in the flow path at a position selected from the group consisting of above and adjacent the at least one liquid outlet. 3. The cartridge of claim 1, wherein the support structure is positioned between the puncturable delivery wall and the bottom wall of the cup forming the collecting area. 4. The cartridge of claim 3, wherein the support structure is integral with the bottom wall of the cup. 5. The cartridge of claim 1, wherein the cartridge comprises a series of outlets placed in a center of the collecting area. 6. The cartridge of claim 5, wherein at least one support surface forms a portion of a disc or a dome that extends transversally beyond the series of outlets. 7. The cartridge of claim 1, wherein the portions of ridges are located in the flow path between the puncturing structure and the outlet. 8. The cartridge of claim 7, wherein the portions of ridges are located concentrically around the liquid outlet with flow passages in-between for interrupting the flow of liquid towards the outlet. 9. The cartridge of claim 7, wherein the puncturing structure forms a plurality of small protrusions. 10. The cartridge of claim 9, wherein the protrusions are arranged concentrically around the outlet(s). 11. The cartridge of claim 9, wherein the puncture structure comprises puncture surfaces of a smaller width or section than a width or section of the support surface of the support structure. 12. The cartridge of claim 1, wherein the puncturing structure comprises a plurality of sharp puncturing forms. 13. The cartridge of claim 1, wherein the support structure comprises portions of ridges positioned in a radial direction with respect to the bottom surface of the cup. 14. The cartridge of claim 1, wherein the lid comprises at least one injection orifice of a small size for forming a jet of the liquid entering the chamber containing the food substance. 15. A cartridge system comprising: a cartridge according to claim 1 and a beverage production device for holding the cartridge and a water injection member;the cartridge contains a food substance adapted to interact with water injected through the water injection member into the cartridge and to produce a food liquid that is dispensed from the cartridge;the cartridge comprises a support structure comprising at least one support surface designed to support at least one portion of the delivery wall and the water injection member being configured to inject water in the chamber under pressure in the form of at least one jet. 16. The cartridge of claim 1, wherein the support structure comprises a disc or a dome that extends transversally beyond the outlet in the same plane as the top of the puncturing structure. 17. The cartridge system of claim 15, wherein the support structure comprises a disc or a dome that extends transversally beyond the outlet in the same plane as the top of the puncturing structure. 18. The cartridge of claim 12, wherein the puncturing forms are selected from the group consisting of crosses, cones and blades. 19. The cartridge of claim 16, wherein the disc or dome is connected to the bottom surface of the collecting area by legs delimiting passages for the liquid to flow in the at least one liquid outlet. 20. The cartridge system of claim 17, wherein the disc or dome is connected to the bottom surface of the collecting area by legs delimiting passages for the liquid to flow in the at least one liquid outlet.
