1. A capsule for containing beverage ingredients intended to produce a beverage in a beverage preparation device upon liquid injection into the capsule and by rotating the capsule around a central axis of the capsule in the beverage preparation device, the capsule comprising: a body comprising a side wall, a bottom wall and a flange-like rim; andan upper wall attached to the flange-like rim and/or the side wall of the capsule, the upper wall and the body enclosing an ingredient compartment for the beverage ingredients,the upper wall comprising a central liquid inlet, peripheral outlet apertures, and an outwardly protruding sealing member, the central liquid inlet forming a circular aperture that communicates with the ingredient compartment, the central liquid inlet configured to accommodate a liquid injection member therethrough,the outwardly protruding sealing member arranged at an annular portion of the upper wall between the central liquid inlet and the peripheral outlet apertures, and designed to at least significantly hinder liquid from flowing at an outside of the capsule from the central liquid inlet to the peripheral outlet apertures when the outwardly protruding sealing member is engaged by the beverage preparation device, the upper wall being free of apertures between the outwardly protruding sealing member and the central liquid inlet, the upper wall is in recess relative to the flange-like rim and the outwardly protruding sealing member, andthe outwardly protruding sealing member located radially distanced from the central liquid inlet. 2. The capsule according to claim 1, wherein the outwardly protruding sealing member is arranged to provide an annular space between an outer surface of an injection member of the beverage preparation device when being engaged through to the central liquid inlet and an inner surface of the outwardly protruding sealing member. 3. The capsule according to claim 1, wherein the outwardly protruding sealing member forms a wall portion protruding from the upper wall in a direction essentially parallel to a rotational axis of the capsule. 4. The capsule according to claim 1, wherein the outwardly protruding sealing member forms a wall portion arranged in a continuous manner about a circumference of the central liquid inlet. 5. The capsule according to claim 1, wherein the outwardly protruding sealing member comprises a tubular wall portion of an inner diameter which is greater than an outer diameter of the central liquid inlet. 6. The capsule according to claim 1, wherein the outwardly protruding sealing member forms several portions of a wall arranged in a discontinuous manner about a circumference of the central liquid inlet. 7. The capsule according to claim 6, wherein the outwardly protruding sealing member is arranged to form a labyrinth wall structure designed to cause the liquid to meander from the central liquid inlet to a peripheral portion of the upper wall. 8. The capsule according to claim 1, wherein the outwardly protruding sealing member is designed for being deflected and/or compressed upon engagement of the capsule within the beverage preparation device. 9. The capsule according to claim 1, wherein the outwardly protruding sealing member comprises at least two portions extending successively in an axial direction, respectively, a base portion and an engagement portion; and the engagement portion is arranged at an end or distal portion of the outwardly protruding sealing member and is softer and/or more flexible than the base portion. 10. The capsule according to claim 9, wherein the engagement portion of the outwardly protruding sealing member is of material designed to soften in presence of hot water to increase a liquid-tight sealing engagement between the central liquid inlet and the peripheral outlet apertures.
