Method for producing a capsule containing beverage ingredients designed for insertion in a beverage production device in which a liquid under pressure enters the capsule in order to interact with the ingredients in the capsule and to drain a beverage from the capsule, wherein the capsule includes a body with a sealing member attached thereto. The method includes providing the body with a main cavity, injecting at least one sealing material by injection-molding onto at least a portion of the external surface of the body to mold a sealing member sealingly attached to the body, filling the cavity with food ingredients and imperviously closing the cavity with a membrane to provide a closed capsule containing the food ingredients.

1. In a method for providing a capsule containing beverage ingredients designed for insertion in a beverage production device in which a liquid under pressure enters the capsule in order to interact with the ingredients in the capsule and to drain a beverage from the capsule, the improvement which comprises providing a body for the capsule and injecting at least one sealing material by injection-molding onto at least a portion of an external surface of the body to mold a sealing member sealingly attached thereto; wherein the sealing member is geometrically arranged to be in sealing engagement with at least a matching surface of the beverage production device. 2. The method according to claim 1, wherein the injected material for the sealing member is different from the material forming the body of the capsule. 3. The method according to claim 1, wherein the injected material for the sealing member is softer than the material forming the body. 4. The method according to claim 1, wherein the body is formed with a flange-like rim and the injection step comprises injecting the sealing member onto the flange-like rim. 5. The method according to claim 4, wherein the flange-like rim comprises an anchoring portion and a support portion; wherein the injection step comprises injecting the sealing member both in the anchoring portion and the support portion. 6. The method according to claim 5, wherein the anchoring portion is formed of a partially curled portion that serves as an opening for plastic to flow therein during injection. 7. The method according to claim 1, wherein the injection is made in injection dies under a pressure of about 500 to 2000 bar and during less than or about a second, and wherein, after injection, the body with its injected sealing member is allowed to cool down during a few seconds in the injection dies. 8. The method according to claim 1, wherein the injected material is a thermoplastic elastomer and the capsule body comprises aluminum. 9. The method according to claim 1, which further comprises pre-forming the capsule body by deep drawing of a metal or metal-plastic sheet. 10. The method according to claim 9, which further comprises providing at least one localized deformation in a sidewall of the capsule body to create anchoring means for the sealing member, wherein the at least one localized deformation is provided by the deep drawing operation. 11. The method according to claim 1, which further comprises providing at least one localized deformation in a sidewall of the capsule body to create anchoring means for the sealing member, wherein the at least one localized deformation is provided during injection or cooling down of the injection-molded sealing member. 12. The method according to claim 1, wherein the capsule body is made of an injection molded material and which further comprises co-injection molding of the capsule body and the sealing member to produce a unitary structure. 13. The method according to claim 1, which further comprises filling the body with food ingredients and imperviously closing the body by welding a membrane to the body to hermetically close it. 14. A capsule for containing beverage ingredients, the capsule being designed for insertion in a beverage production device in which a liquid under pressure enters the capsule in order to interact with the ingredients in the capsule and to drain a beverage from the capsule, with the capsule including a sealing member on an outer surface of the capsule body member, wherein the sealing member is geometrically arranged to be in sealing engagement with at least a matching pressing surface of a beverage production device, wherein the capsule comprises a body for holding the beverage ingredients with the body having a flange-like rim with the sealing member attached thereto; and further wherein the sealing member is made of injection-molded material and is affixed to the external surface of the flange-like rim. 15. The capsule according to claim 14, wherein the sealing member is made of a material that is softer than the material of the body. 16. In a method for providing a capsule containing beverage ingredients designed for insertion in a beverage production device in which a liquid under pressure enters the capsule in order to interact with the ingredients in the capsule and to drain a beverage from the capsule, the improvement which comprises providing for the capsule a body that includes a flange extending from a sidewall, and injecting at least one sealing material by injection-molding onto at least a portion of the flange that is adjacent an external surface of the body to mold a sealing member sealingly attached thereto, such that the sealing member of the capsule is geometrically arranged to be in sealing engagement with a pressing surface of the beverage production device to provide liquid-tightness during brewing of the beverage ingredients. 17. The method according to claim 16, wherein the flange-like rim comprises an anchoring portion and the injection step includes further injecting the sealing member into the anchoring portion. 18. The method according to claim 16, wherein the injection step includes further injecting the sealing member onto a portion of the sidewall of the capsule. 19. A capsule for containing beverage ingredients, the capsule being designed for insertion in a beverage production device in which a liquid under pressure enters the capsule in order to interact with the ingredients in the capsule and to drain a beverage from the capsule, with the capsule having a body that includes a flange extending from a sidewall and that has a sealing member provided on at least a portion of the flange that is adjacent an external surface of the body, wherein the capsule body holds the beverage ingredients therein, and the sealing member is made of injection-molded material and is geometrically arranged to be in sealing engagement with a pressing surface of a beverage production device to provide liquid-tightness during brewing of the beverage ingredients. 20. The capsule according to claim 19, wherein the flange-like rim comprises an anchoring portion and the sealing member extends into the anchoring portion. 21. The capsule according to claim 19, wherein the sealing member extends onto a portion of the sidewall of the capsule.
