Abstract
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.
