A capsule for making beverages, containing a powdered food substance which can be extracted by passing hot water through it, the capsule (1) comprising a cup-shaped containment body (3) which inside it forms a chamber (2) for housing (16) the powdered food substance, and which comprises a bottom portion (7) through which, in use, hot water can be fed into the capsule (1), and a lateral wall (4) connected to the bottom portion (7) and forming an access opening for accessing the chamber (2), and a closing element (9) fixed to the lateral wall (4) at the access opening for closing it, and through which, in use, the beverage can come out of the chamber (2). The capsule (1) also comprises a filter element (10) which is permeable to water and positioned inside the chamber (2) between the powdered food substance and the bottom portion (7), the filter element (10) resting on the bottom portion (7) and being free to move away from the latter towards the inside of the chamber (2) except for the resistance applied by the powdered food substance. The invention also relates to a system for making beverages which comprises the capsule (1).

1. A system for making beverages comprising an extraction device (14) and a capsule (1) for making beverages, the capsule being intended to be used in the extraction device by making a flow of hot water pass through the capsule, wherein the capsule (1) comprises: a cup-shaped containment body (3) which inside it forms a chamber (2), the containment body (3) comprising a bottom portion (7) and a lateral wall (4), the lateral wall (4) being connected to the bottom portion (7) and forming an access opening for accessing the chamber (2);a powdered food substance, contained in the capsule and housed in the chamber (2), the powdered food substance allowing a beverage to be made by passing hot water through it;a closing element (9) fixed to the lateral wall (4) at the access opening for closing it;a filter element (10) which is permeable to water and is positioned inside the chamber (2) between the powdered food substance and the bottom portion (7), the filter element (10) resting on the bottom portion (7) and being free to move away from the latter towards the inside of the chamber (2), except for the resistance applied by the powdered food substance, in such a way that the whole filter element (10) is movable between a first position, in which the filter element (10) rests on the bottom portion (7), and a second position, in which the whole filter element (10) is spaced apart from said bottom portion (7); the bottom portion (7) of the capsule (1) constituting, in use, an infeed section for feeding hot water into the capsule (1) and the closing element (9) of the capsule (1) constituting, in use, an outfeed section through which the beverage can come out of the chamber (2); wherein the extraction device (14) comprises: a first part (15) comprising a housing (16) for the capsule (1), and a second part (17), the first part (15) and the second part (17) being mobile one relative to the other between an operating position in which they clamp between them the capsule (1) inserted in the housing (16), and a home position in which they allow the insertion and removal of the capsule (1) respectively in and from the housing (16);one or more piercing elements (20) associated with the housing (16) for piercing the bottom portion (7) of the capsule (1) inserted in the housing (16) at least when the first part (15) and the second part (17) are in the operating position;water feeding means operatively associated with the housing (16) for in use supplying water into the capsule (1) through the bottom portion (7) pierced by the one or more piercing elements (20);piercing means designed to pierce the closing element (9) at least when the capsule (1) is inserted in the housing (16), the first part (15) and the second part (17) are in the operating position and the pressure in the chamber (2) exceeds a predetermined value; wherein, when the capsule (1) is inserted in the housing (16) and the first part (15) and the second part (17) are in the operating position, the one or more piercing elements (20) hold the whole filter element (10) in the second position in which the whole filter element (10) is spaced apart from the bottom portion (7). 2. The system according to claim 1, characterised in that the powdered food substance housed in the chamber (2) is partly compressible, the powdered food substance being partly compressed when the filter element (10) is spaced apart from said bottom portion (7). 3. The system according to claim 1, characterised in that the filter element (10) is sized and made of materials such that, in use, said one or more piercing elements (20) of the extraction device cause the filter element (10) to move into the second position without completely piercing the filter element (10), the one or more piercing elements (20) being only partly inserted in the filter element (10) without completely passing through it. 4. The system according to claim 1, characterised in that the filter element (10) comprises at least one layer of material which is permeable to water. 5. The system according to claim 4, characterised in that the layer of material permeable to water is made of non-woven fabric or of compacted fine synthetic fibres. 6. The system according to claim 4, characterised in that the layer of material permeable to water has a thickness equal to at least five times the average thickness of the bottom portion (7). 7. The system according to claim 4, characterised in that the layer of material permeable to water is a rigid or semi-rigid pierced body and is made of plastic material. 8. The system according to claim 1, characterised in that the bottom portion (7) comprises at least a first sheet (11) of a material having a resistance to piercing and tearing which is less than that of the material constituting the lateral wall (4). 9. The system according to claim 8, characterised in that the bottom portion (7) also comprises a rigid or semi-rigid annular zone (12) forming a single piece with the lateral wall (4) and to which said at least one first sheet (11) is fixed. 10.
