1. A capsule for containing beverage ingredients, for the preparation of a beverage by injection of a liquid into the capsule, comprising: a sealed ingredient compartment containing beverage ingredients;an inlet face having outer and inner sides and dedicated for injection of liquid into the capsule to form a beverage from the beverage ingredients;an outlet face dedicated for the delivery of the beverage;an aperture in the inlet face of the capsule;a membrane attached to a portion of the inner side of inlet face which surrounds the aperture, wherein the membrane is attached to the inlet face portion by a first circumferential section in detachable sealing engagement therewith; anda second circumferential section, radially offset from the first circumferential section, for attaching the membrane to the inner side of the inlet face of the capsule in a manner that presents channels between the second circumferential section and the inlet face when deflecting the membrane, wherein the channels guide liquid injected into the aperture to the ingredients compartment of the capsule. 2. The capsule according to claim 1, wherein the aperture in the inlet face of the capsule is circular. 3. The capsule according to claim 2, wherein the first circumferential section forms a continuous ring-shaped closing portion surrounding the circular aperture. 4. The capsule according to claim 1, wherein the first circumferential section is delaminable from the membrane or the inner side of the portion of the inlet face surrounding the aperture. 5. The capsule according to claim 1, wherein the second circumferential section comprises a plurality of non-delaminable segments which are fixedly connecting the membrane to the inner side of the portion of the inlet face surrounding the aperture. 6. The capsule according to claim 5, wherein the non-delaminable segments radially extend from the first circumferential section. 7. The capsule according to claim 1, wherein the channels are formed by radially recesses extending from the second circumferential section toward the first circumferential section. 8. The capsule according to claim 1, wherein the first circumferential section is a relatively soft or weak adhesive that has sufficient strength to form a gas tight seal. 9. The capsule according to claim 8, which further comprises a second, circumferential section, radially offset from the first circumferential section, for attaching the membrane to the inner side of the inlet face of the capsule, wherein the second circumferential section is formed by a relatively stronger adhesive or sealing material than the first circumferential section. 10. The capsule according to claim 1, which further comprises a filter within the channels. 11. A capsule for containing beverage ingredients, for the preparation of a beverage by injection of a liquid into the capsule, comprising: a sealed ingredient compartment containing beverage ingredients:an inlet face having outer and inner sides and dedicated for injection of liquid into the capsule to form a beverage from the beverage ingredients;an outlet face dedicated for the delivery of the beverage:an aperture in the inlet face of the capsule; anda membrane attached to a portion of the inner side of inlet face which surrounds the aperture wherein the membrane is attached to the inlet face portion by a first circumferential section in detachable sealing engagement therewith;wherein the membrane and an inner side of the inlet face of the capsule body are superposed and designed to form a non-return valve in the area of the liquid injection passages. 12. The capsule according to claim 11, wherein the ingredients compartment of the capsule and the membrane attached to the inlet face of the capsule are made of plastics or aluminum. 13. The capsule according to claim 11, wherein the first circumferential section is delaminable from the membrane or the inner side of the portion of the inlet face surrounding the aperture. 14. A system for preparing a beverage from a food substance contained in the ingredients compartment of a capsule by injection of a liquid therein, the capsule comprising: a sealed ingredient compartment containing beverage ingredients;an inlet face having outer and inner sides and dedicated for injection of liquid into the capsule to form a beverage from the beverage ingredients;an outlet face dedicated for the delivery of the beverage;an aperture in the inlet face of the capsule;a membrane attached to a portion of the inner side of inlet face which surrounds the aperture, wherein the membrane is attached to the inlet face portion by a first circumferential section in detachable sealing engagement therewith, andthe system comprising:a device which has at least one enclosing member connected to a closing mechanism for selectively enclosing the capsule in a receiving chamber of the device,a pump for supplying liquid to the capsule, andliquid injection means for providing a liquid under pressure to the membrane covering the capsule aperture at an inlet face thereof,wherein the detachable sealing engagement is designed to be disengaged from the capsule body or the membrane by deflection of the membrane due to the effect of a pressure being provided to the inlet side of the capsule. 15. The system according to claim 14, wherein the first circumferential section of the capsule is delaminable from the membrane or the inner side of the portion of the inlet face surrounding the aperture. 16. The system according to claim 14, wherein the capsule further comprises a second circumferential section, radially offset from the first circumferential section, for attaching the membrane to the inner side of the inlet face of the capsule in a manner that presents channels between the second circumferential section and the inlet face when deflecting the membrane, wherein the channels guide liquid injected into the aperture to the ingredients compartment of the capsule. 17. The system according to claim 16, wherein the second circumferential section of the capsule comprises a plurality of non-delaminable segments which are fixedly connecting the membrane to the inner side of the portion of the inlet face surrounding the aperture. 18. A system for preparing a beverage from a food substance contained in a ingredients compartment of a rigid capsule by injection of a liquid into the capsule, the system comprising: a device which has at least one enclosing member connected to a closing mechanism for selectively enclosing the capsule in a receiving chamber of the device,a pump for supplying liquid to the capsule, andliquid injection means for providing a liquid under pressure to a membrane covering an aperture provided at an inlet face of the capsule,wherein the membrane of the capsule is connected to an inner surface of the inlet face of the capsule by at least one circumferential section that is in detachable sealing engagement,wherein the detachable sealing engagement is designed to be disengaged from the capsule body or the membrane by deflection of the membrane due to the effect of a pressure being provided to the inlet side of the capsule. 19. A method for connecting a capsule comprising at least a rigid body having a circular aperture and a membrane for covering the aperture by means of a sealing engagement, which method comprises: applying sealing means to an outer rim portion of the membrane, wherein the sealing means comprise a first circumferential portion and a second circumferential portion being arranged radially offset to each other and wherein the second circumferential portion comprises recesses extending radially from the first circumferential portion, andconnecting the membrane to the inner side of the portion of the inlet face surrounding the aperture by the sealing means.
