A sealed capsule contains a beverage ingredient in powder form, in particular, ground coffee. The capsule comprises a base body (4) and a foil member (5) tightly attached to the base body (4), the foil member (5) being made from a material allowing the production of a multitude of perforations in the foil member (5) when the foil member (5) is thrust, via the pressure caused by injecting a liquid or a liquid/gas mix into the capsule, against a relief plate of a beverage production machine, wherein the capsule is provided with a flow control porous member (80), the flow control porous member (80) being positioned between at least a portion of ingredients (3) and the foil member (5). The flow control porous member provides a faster and more consistent flow of the liquid extract through the capsule and significantly reduces the resurgence of non-soluble solids.

La présente invention concerne une capsule scellée contenant un ingrédient de boisson en poudre, en particulier du café moulu. La capsule comprend un corps de base (4) et un élément en feuille (5) étroitement solidaire du corps de base (4). Cet élément en feuille (5) est fait d'une matière permettant la production d'une multitude de perforations dans l'élément en feuille (5) quand la pression crée par l'injection d'un liquide ou d'un mélange liquide/gaz dans la capsule applique cet élément en feuille (5) contre une plaque à reliefs d'une machine de production de boissons. La capsule est pourvue d'un élément poreux régulateur de flux (80) disposé entre au moins une partie des ingrédients (3) et l'élément en feuille (5). L'élément poreux régulateur de flux assure un flux plus rapide et plus régulier de l'extrait liquide au travers de la capsule, tout en réduisant de façon importante la résurgence de solides insolubles.
