1. A cartridge (1) for coffee or soluble products for the production of a beverage on an extraction apparatus by means of pressurised water or other extraction fluid, comprising: a container body (10), hermetically closed at opposite bases thereof (30, 20), respectively, for water input and for beve
1. A cartridge (1) for coffee or soluble products for the production of a beverage on an extraction apparatus by means of pressurised water or other extraction fluid, comprising: a container body (10), hermetically closed at opposite bases thereof (30, 20), respectively, for water input and for beverage output from the cartridge,wherein said body (10) is of a hollow tubular type, and said opposite bases (30, 20) are membranes comprising a non-elastic barrier film (32, 22), an elastic plastic film (33, 23), and an adhesive provided therebetween,wherein on at least one of said membranes (20, 30), a plurality of small incisions (40, 41), that facilitate a breakage of the corresponding membrane (30, 20) at a predetermined pressure of the fluid in the apparatus for the extraction of the beverage, are provided on said plastic film (23, 33) at small areas of said plastic film that are free of the adhesive between the plastic film (23, 33) and the barrier film (22, 32), such to cause, following an increase in the pressure of the fluid, formation of small apertures at said small areas free of the adhesive and the tearing of only said small areas free of the adhesive, preventing the tearing from propagating to areas where said plastic film (23,33) and said barrier film (22,32) of said membrane (20,30) are glued one to the other by the adhesive. 2. The cartridge (1) according to claim 1, wherein said areas free of the adhesive between the plastic film (23) and the barrier film (22) are provided on the membrane (20) positioned on the beverage output side. 3. The cartridge (1) according to claim 1, said areas free of the adhesive between the plastic film (23, 33) and the barrier film (22, 32) are provided on both membranes (20, 30). 4. The cartridge (1) according to claim 1, wherein said at least one incision (40) is a cut which involves the whole thickness of the plastic film (33, 23). 5. The cartridge (1) according to claim 1, wherein said incision (41) involves only part of the thickness of said plastic film (33, 23) causing a weakening thereof. 6. The cartridge (1) according to claim 1, wherein said membranes (30, 20) are respectively anchored to an inner annular flange (12) and an outer annular flange (11) provided at the respective opposite ends of said body (10). 7.

The cartridge (1) according to claim 7, wherein said filter (31) is placed externally or internally with respect to said inner annular flange (12). 9. The cartridge (1) according to claim 1, wherein said body (10) is in plastic material, and said membranes (30, 20) comprise the respective films (33, 23) in plastic material in contact with said body (10). 10. The cartridge (1) according to claim 1, wherein said body (10) is in aluminum and said membranes (30, 20) comprise said film (32, 22) in aluminum in contact with said body (10). 11. The cartridge (1) according to claim 1, wherein said at least one incision (40, 41) is obtained by means of laser. 12. The cartridge (1) according to claim 1 wherein said body (10) is cylindrical, truncated cone, truncated pyramid or another shape. 13. The cartridge (1) according to claim 1, wherein said plastic films (33, 23) are coupled to the respective aluminum films (32, 22) through lamination by means of a respective layer of adhesive. 14. The cartridge (1) according to claim 6, wherein respective filters (31, 21) in nonwoven fabric are provided inside said membranes (30, 20). 15. The cartridge (1) according to claim 1, wherein the non-elastic barrier film is aluminum. 16. The cartridge (1) according to claim 1, wherein each membrane respectively comprises only one elastic plastic film. 17. The cartridge (1) according to claim 9, wherein the plastic material is any of polypropylene, coextruded PP/EVOH/PP, PLA, or, PBT, and the plastic material is cast PP.
