A cartridge (1) for coffee and for soluble products is described, which comprises a container (2) designed to contain the coffee or the soluble product, a lid (6) placed on the top of the container so as to define an upper wall designed to allow hot water under pressure to enter the container (2) in order to produce the beverage, a filter (4) designed to be positioned inside the container (2) above a bottom wall (20) of the container. The bottom wall (20) of the container has at least one breakable portion (28) designed to break when the liquid inside the cartridge reaches a pre-set pressure, so as to form at least one aperture (130) to allow the beverage to be extracted from the cartridge (1)a.

The invention claimed is: 1. A cartridge (1; 200) for coffee or soluble products for the production of a beverage, comprising: a container (2) designed to contain coffee or soluble product, a lid (6) set on the top of the container so as to define an upper wall through which hot water under pressur
The invention claimed is: 1. A cartridge (1; 200) for coffee or soluble products for the production of a beverage, comprising: a container (2) designed to contain coffee or soluble product, a lid (6) set on the top of the container so as to define an upper wall through which hot water under pressure enters the container (2) in order to produce the beverage, and a filter (4) designed to be positioned inside said container (2) above a bottom wall (20) of the container through which the beverage leaves, wherein said bottom wall (20) of the container has at least one breakable portion (28) designed to break when the liquid inside the cartridge reaches a pre-set pressure, so as to form at least one aperture (130) to allow the beverage to be extracted from the cartridge (1), said at least one breakable portion (28) being obtained by means of grooves (27) formed in a weakened portion (22) of the bottom wall (20) of the cartridge (1) so that at least one breakable portion (28) is thinner than the weakened portion (22). 2. A cartridge (1; 200) of claim 1, wherein said weakened portion (22) is thinner than the bottom wall (20) of the cartridge (1). 3. A cartridge (1; 200) of claim 1, wherein said weakened portion (22) is substantially circular in shape and is set in a central portion of said bottom wall (20). 4. A cartridge (1; 200) of claim 1, comprising two breakable portions (28) arranged in a cross shape. 5. A cartridge (1; 200) of claim 1, wherein in the inner surface of the bottom wall (20) there are provided ribs (24, 24', 24") designed to support said filter (4) so as to define a chamber between said filter (4) and said bottom wall (20) to flow the filtered beverage out. 6. A cartridge (1; 200) of claim 1, wherein said lid (6) is made through one or more layers of micro-perforated material to allow the passage of hot water under pressure into the cartridge (1). 7. A cartridge (1; 200) of claim 1, wherein said container (2) is made by injection moulding of plastic material, such as polypropylene and the like. 8. An apparatus (300) for extraction of a beverage comprising: a top plate (102) provided with at least one hole (121) through which the pressurised hot water passes, and a filter-holding container (301) into which is inserted a filter, which can be coupled beneath said top plate (102) and is provided with at least one outlet hole (110) through which the beverage is extracted, wherein on the top rim (303) of said filter holder there is formed a substantially knurled surface (305) designed to cooperate with the matching knurled bottom surface (232) of the top rim (30) of a cartridge (200), according to claim 7, designed to be inserted in said filter holder (301), to avoid relative rotation of the cartridge (200) with respect to the filter holder (301), wherein said top plate (102) has a plurality of blades (320) projecting downward to pierce the lid (6) of the cartridge (200), inserted in said filter holder (301). 9. A method of producing a beverage from a cartridge (1; 200), containing coffee or a soluble product, comprising: introduction of hot water under pressure into the cartridge, through the lid (6) of said cartridge, maintaining the pressure inside the cartridge for an optimal pre-set time, so that the aromas of the coffee or of the soluble product dissolve in the hot water under pressure, and breakage of at least one breakable portion (28) obtained by means of grooves (27) formed in a weakened portion (22) of the bottom wall (20) of said cartridge, due to the pressure of the hot water under pressure inside it, so as to allow the beverage to be extracted from said cartridge through at least one aperture (130) obtained by breaking said at least one breakable portion (28).
