Method for producing a capsule (1) 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 comprises a body (4) with a sealing member attached thereto. The method comprises providing a body (4) with a main cavity, injecting at least one sealing material by injection-moulding onto at least a portion of the external surface of the body (4) to mould a sealing member (8) sealingly attached to the body, filling the cavity with food ingredients and imperviously closing the cavity with a membrane (5) to provide a closed capsule containing the food ingredients.
