The capsule according to claim 6, wherein the filtering body is coupled to the coupling portion by mechanical interference and/or the filtering body is in sealed contact with it. 9. The capsule according to claim 2, wherein the layer of flexible filtering material is applied at all of the openings made through the rigid or semi-rigid skeleton. 10. The capsule according to claim 9, wherein all of the openings made in the rigid or semi-rigid skeleton are of a size such that they act as a filter for the powdered food substance. 11. The capsule according to claim 9, wherein the filtering body is coupled to the coupling portion by mechanical interference and/or the filtering body is in sealed contact with it. 12. The capsule according to claim 2, wherein all of the openings made in the rigid or semi-rigid skeleton are of a size such that they act as a filter for the powdered food substance. 13. The capsule according to claim 2, wherein the second side wall is distanced from the first side wall at least for most of its extension and/or wherein the distance between the second side wall and the first side wall increases proceeding from the upper rim towards the bottom portion. 14. The capsule according to claim 2, wherein the filtering body is coupled to the coupling portion by mechanical interference and/or the filtering body is in sealed contact with it. 15. The capsule according to claim 2, wherein, close to the upper rim, the filtering body comprises a shoulder which is substantially annular about the axis of extension and which projects radially relative to the rest of the filtering body with reference to the axis of extension, and wherein the coupling portion comprises a counter-shoulder which is substantially annular about the axis of extension and also projects radially, with reference to the axis of extension, relative to the portion of the first side wall adjacent to it on the lower wall side, said shoulder resting on the counter-shoulder and said upper rim being coupled to an annular region of the coupling portion located between the counter-shoulder and the upper edge. 16. The capsule according to claim 2, wherein the bottom portion of the filtering body is at least partly spaced from the lower wall to allow, during use, insertion of a piercing element in the capsule, through the lower wall, without the bottom portion of the filtering body being damaged. 17.
