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.

1. A capsule for use in a beverage production machine, the beverage production machine comprising a member that perforates an inlet side of a body of the capsule opposed to a foil member and a flange-like rim and injects a liquid or a liquid/gas mix into the capsule; and a relief plate having a mult
1. A capsule for use in a beverage production machine, the beverage production machine comprising a member that perforates an inlet side of a body of the capsule opposed to a foil member and a flange-like rim and injects a liquid or a liquid/gas mix into the capsule; and a relief plate having a multitude of relief elements, the relief plate is positioned in the machine such that injection pressure urges the foil member against the relief plate; and the capsule comprising: a base body sealed off by the foil member tightly attached to the flange-like rim of the base body, the foil member (i) having a thickness between 15 and 45 microns, (ii) being constructed from a material selected from the group consisting of aluminum, aluminum alloy, a laminate of aluminum and a polymer, a laminate of aluminum alloy and a polymer, and combinations thereof, and (iii) when perforated by the relief plate, forms a multitude of openings when the pressure of the injected liquid or liquid/gas mixture reaches a value of at least 4 bar, wherein the base body contains ground coffee having a particle size between 190 and 400 microns; anda flow control porous member positioned between at least a portion of ingredients in the capsule and the foil member, the flow control porous member having a pore size of between 0.4 and 2 microns,wherein the porous member is made of at least one thin polymeric membrane having a thickness between 0.4 microns and 1.0 mm, and is made of a material selected from the group consisting of polypropylene, polyethylene, PBT, Nylon, polycarbonate, poly(4-methyl pentene-), polyurethane, PET, polyethersulfone, polyamide, resin bonded-glass fibers and combinations thereof. 2. The capsule of claim 1, wherein a thickness ratio of the flow control porous member to the foil member is between 5:1 and 20:1. 3. The capsule of claim 1, wherein the flow control porous member is thicker than the foil member. 4. The capsule of claim 1, wherein the flow control porous member comprises essentially polymeric fiber-containing material and is made from a woven and/or non-woven material. 5. The capsule of claim 1, wherein the flow control porous member is adjacent to the foil member. 6. The capsule of claim 5, wherein the foil member and the flow control porous member form a multilayer laminate. 7. The capsule of claim 1, wherein the flow control porous member has a shape selected from the group consisting of square and rectangular. 8. The capsule of claim 1, wherein the flow control porous member comprises microfibres of a diameter less than 20 microns. 9. The capsule of claim 1, wherein the base body is made from a material selected from the group consisting of aluminum, aluminum alloy, a laminate of aluminum and a polymer, a laminate of aluminum alloy and a polymer, and combinations thereof.
