- the present invention relates to a capsule for extracting a pressurized beverage, of the type comprising an axially extending side wall, a fluid inlet wall closing a first axial end of the side wall, and a wall fluid outlet closing a second axial end of the side wall, the side walls, inlet and outlet delimiting between them a receiving chamber of a substance for the preparation of a beverage, the inlet wall being provided for breaking under the effect of a fluid under pressure and comprising a concavity dome turned towards the inside of the capsule.
- capsules are known for the extraction of a drink under pressure. These capsules are intended to be inserted in beverage preparation machines, in which an extraction fluid, usually water, is injected into the capsule to extract the substance they contain. The extraction fluid enters the capsule through the inlet wall, and exits, mixed with the substance, through the outlet wall.
- an extraction fluid usually water
- a major problem for manufacturers of this type of capsule is to keep the substance safe from air and moisture.
- some capsules are marketed in a packaging providing the function of barrier to air and moisture. Once removed from their packaging, these capsules are ready to be used in beverage preparation machines. Other capsules are waterproof to protect the substance they contain. To allow the extraction of these capsules, some beverage preparation machines are equipped with means for drilling the inlet wall and the outlet wall of these capsule types.
- the sealed capsules are more satisfactory than the packaged capsules because they limit the volume of waste and the manipulations of the user.

- the membrane is provided to partially disengage from the body of the capsule under the effect of a fluid under pressure.
- the capsule is sealed during its introduction into the beverage preparation machine, and opens under the sole effect of the injected fluid pressure.
- the capsule disclosed in this document is not entirely satisfactory. Indeed, the pressure of separation of the membrane proves to be difficult to control. In addition, the capsule is of complex manufacture.
- An object of the invention is therefore to provide a capsule having an airtight and moisture-tight inlet wall adapted to rupture under the effect of a fluid under pressure and whose breaking pressure is easily controllable. Other objectives are to minimize the cost of the capsule and to optimize the extraction of the substance contained in the capsule.

- the dome 16 also includes a plurality of lines of weakness 30. These lines of weakness are at least three in number. As can be seen in FIG. 1, each of these lines of weakness 30 is formed by a zone of lesser thickness of the dome 16. With reference to FIG. 2, the lines of weakness 30 converge towards a point of convergence 32. This convergence point 32 is substantially at the center of the dome 16, that is to say that it is located in a disk centered on the center of the dome 16 and of radius equal to 20%, preferably equal to 10%, of the distance separating the center of the dome 16 from the periphery of the dome 16.

- the lines of weakness 30 delimit between them dome sectors 34.
- Each dome sector 34 has a thickness greater than that of the lines of weakness 30.
- a material bridge 36 located at the point of convergence 32, joins the dome sectors 34 each other. This material bridge 36 has a strength greater than that of the lines of weakness 30. It has a thickness greater than that of the dome sectors 34.
- the material bridge 36 is typically the injection point of the plastic material during manufacture of the body 4.
- the lines of weakness 30 are regularly distributed over the dome 16, that is to say they delimit dome sectors 34 of substantially the same dimensions.
- the lines of weakness 30 are four in number and form a cross substantially centered on the dome 16.
- the rupture pressure of the lines of weakness 30 can be easily controlled by adjusting their number and the thickness of the dome sectors 34.
- the openings formed in the inlet wall 8 by the rupture of the lines of weakness 30 remain narrow, which prevents a part of the substance contained in the capsule does not release these openings, which would require cleaning of the beverage preparation machine after each use.
- the dome 16 transmits a portion of the axial force to the zone of weakness 26, which is stressed in axial tension as illustrated by the arrows F1 in FIG. Since the dome 16 tends to collapse axially by expanding radially at its periphery, it also biases the zone of weakness 26 radially outwards as illustrated by the arrows F2 in FIG. The zone of least resistance 26 is thus axially biased in its direction of extension and in shear in its direction of lesser thickness. As a result, the zone of least resistance 26 easily breaks under controlled pressure.
