Capsule for preparing beverages

A capsule, intended for the preparation of a beverage in a device for making the beverage, the capsule comprising a body which includes

• a bottom wall;
• a side wall extending around a longitudinal axis between a first annular edge, connected to the bottom wall, and a second annular edge, wherein the side wall has an inside surface, facing towards the longitudinal axis, and an outside surface, opposite to the inside surface;
• and
• an annular flange, extending from the second annular edge of the side wall, away from the longitudinal axis,
• wherein the outside surface of the side wall includes a first portion, which is proximal to the flange, and a second portion, which is distal from the flange;
• wherein the second annular edge has a diameter that is greater than or equal to 40 mm and wherein the capsule has a length that is greater than or equal to 35 mm along the longitudinal axis,
• wherein the body includes a plurality of protrusions disposed around the longitudinal axis and projecting from the first portion of the outside surface of the side wall, so each of the plurality of protrusions produces local thickening of the side wall,
• wherein the annular flange has a rear face, which is directed towards the bottom wall, and a front face opposite to the rear face, wherein the body includes a plurality of protuberances, disposed around the longitudinal axis and projecting from the rear face of the annular flange, so each protuberance of the plurality of protuberances produce local thickening of the annular flange, the number of protrusions of the plurality of protrusions being equal to the number of protuberances of the plurality of protuberances and each protuberance of the plurality of protuberances being joined to a corresponding protrusion of the plurality of protrusions, so that each protuberance constitutes an extension of the corresponding protrusion onto and along the rear face of the flange.
