1. A disposable capsule for preparing a beverage from a food product housed therein, comprising: a plurality of walls,means for dispensing said beverage,means for supplying a fluid inside the capsule,a film for isolating said supplying means from an external environment to the capsule that is provided on an upper part of the capsule, the film being a first wall among the plurality of walls; andmeans for perforating said film, wherein said means for perforating said film are fixed with respect to the capsule and are positioned on a second wall among the plurality of walls of the capsule between said second wall and the film to perforate the film when the film is pressed down by incoming water, and at least a portion of the film is movable between a rest position in which the film isolates said supplying means and a position where said perforating means engage and perforate the film so that said supplying means supplies the fluid inside the capsule and said dispensing means dispenses said beverage. 2. The disposable capsule according to claim 1, wherein said film is deformable and said film perforates by said perforating means when deformed under a pressure exerted by pressurized hot water directed to said capsule and to said film to prepare said beverage. 3. The disposable capsule according to claim 1, wherein said film is secured to a deformable portion of the capsule that is on a lateral wall among the plurality of walls of the capsule. 4. The disposable capsule according to claim 1, wherein said means for perforating said film are inside the capsule. 5. The disposable capsule according to claim 1, wherein said means for perforating said film comprise one or more cutting projections, arranged on the second wall of the capsule, which underlies the film. 6. The disposable capsule according to claim 5, wherein said cutting projections are arranged in correspondence with through holes provided in said second wall of the capsule, which underlies the film. 7. The disposable capsule according to claim 6, wherein said through holes are oblique with respect to the vertical axis of the capsule. 8. The disposable capsule according to claim 5, wherein at least a part of an upper wall of said capsule includes said film and said projections are fixed to one or more internal walls of said capsule. 9. The disposable capsule according to claim 1, wherein said film is a multi-layer film comprising films including a plastic material, aluminium, and labels. 10. The disposable capsule according to claim 1, wherein said means for dispensing said beverage include on a bottom wall among the plurality of walls of the capsule one of a trap having a substantially square shape and being pierceable by a piercing element, external to the capsule, that has a substantially circular section a diameter of which is lower than, or equal to, the side of said trap, and an opening closed by a frangible film. 11. A disposable capsule according to claim 1, further comprising an element for partitioning the internal volume of the capsule. 12. A method for opening a capsule for the preparation of a beverage from a food product housed therein, the method comprising: providing said capsule including a plurality of walls,providing means for dispensing said beverage,providing means for feeding a fluid to the capsule,providing a film for isolating said feeding means from an external environment to the capsule, the film being a first wall among the plurality of walls, and with means positioned on a second wall among the plurality of walls of the capsule between the second wall and the film for perforating said film, andbringing said film in contact with at least a part of said perforation means to perforate the film when the film is pressed down by incoming water so that said feeding means feeds the fluid to the capsule and said dispensing means dispenses said beverage. 13. A method according to claim 12, further comprising applying a pressure to at least a portion of said film in order to deform the film and bring the film into contact with said means for perforating said film. 14. A method according to claim 12, wherein said bringing said film in contact with at least a part of said perforation means includes said perforation means perforating the film when the film deforms under a pressure exerted by pressurized hot water directed to said capsule and to said film to prepare said beverage. 15. A method according to claim 14, wherein said incoming water flows through two or more internal volumes of said capsule, each volume containing at least a product. 16. The disposable capsule according to claim 2, wherein said film is secured to a deformable portion of the capsule that is on a lateral wall among the plurality of walls of the capsule. 17. A disposable capsule for preparing a beverage from a food product housed therein, comprising: a plurality of walls,an opening that dispenses said beverage,at least one orifice that supplies a fluid inside the capsule,a film that isolates the at least one orifice from an external environment to the capsule, the film being a first wall among the plurality of walls; andprotrusions that penetrate said film, said protrusions being fixed with respect to the capsule and positioned on a second wall among the plurality of walls of the capsule between said second wall and the film to perforate the film when the film is pressed down by incoming water so that the at least one orifice supplies the fluid inside the capsule and the opening dispenses said beverage, at least a portion of the film being movable between a rest position and a position where the film engages said protrusions. 18. The disposable capsule according to claim 1, wherein said second wall is an upper wall among the plurality of walls of the capsule. 19. The disposable capsule according to claim 1, wherein said second wall is at least one of a lateral wall and a bottom wall among the plurality of walls of the capsule.
