A capsule for the preparation of a nutritional product in a device adapted to supply liquid into the capsule. The capsule includes at least one compartment containing nutritional ingredients for the preparation of the nutritional product in combination with the supplied liquid, and a filter adapted for removing contaminants contained in the liquid. The capsule also has a selectively openable gas inlet which is placed on or in the capsule to allow gas introduction from outside the capsule into the compartment without passing through the filter.

1. A capsule for the preparation of a nutritional product in a device adapted to supply liquid into the capsule, the capsule comprising: a body comprising a side wall that delimits the body into a filter receiving seat and a compartment;the compartment containing nutritional ingredients for the preparation of the nutritional product in combination with the supplied liquid;a filter unit adapted for removing contaminants contained in the liquid, the filter unit comprising a microporous membrane encased in a rigid casing, the microporous membrane comprising a filtering surface, the casing comprising an inlet wall and an outlet wall, the casing is positioned in the filter receiving seat; andthe filter-receiving seat is positioned upstream of the compartment and is formed by an extension portion of the body that extends radially outward from the side wall of the body such that the seat is laterally offset from the compartment and at least 60% of the filtering surface of the microporous membrane does not overlap the compartment;a top membrane that closes and seals the compartment and seals the filter unit in the filter-receiving seat;a selectively openable gas inlet formed in the inlet wall to allow gas introduction from outside the capsule into the compartment containing the nutritional ingredients without passing through the microporous membrane;an outlet nozzle communicating with the compartment and formed in the outlet wall; anda liquid conduit in the filter unit and placed upstream of the outlet nozzle and downstream of the microporous membrane,wherein the gas inlet has a defined size, in open configuration, and is provided in a the inlet wall of the casing, and the gas inlet merges with the liquid conduit. 2. The capsule according to claim 1, wherein the gas inlet is sealed by a puncturable membrane or comprises a breakable closing portion. 3. The capsule according to claim 1, wherein the microporous membrane has a cross section, taken along a transversal plane of the capsule, which is smaller than the cross section, in the transversal plane, of the compartment containing the ingredients. 4. The capsule according to claim 1, wherein the inlet wall and the outlet wall of the casing form an inner compartment in which the microporous membrane is inserted, and the microporous membrane has a circumference at which the microporous membrane is liquid imperviously sealed to the casing to force liquid entering the inlet wall to traverse the microporous membrane before reaching the outlet wall. 5. The capsule according to claim 4, wherein the casing is formed of two half-casings which are connected or joined together and with the microporous membrane at its circumference. 6. A method of delivering a nutritional product using the capsule according to claim 1, the method comprises supplying a liquid to the compartment to form the nutritional product using the nutritional ingredients within the compartment, and releasing the nutritional product through the outlet nozzle of the capsule according to claim 1, wherein prior to the supplying step, filtering the liquid through the microporous membrane to remove contaminants contained in the liquid and subsequently supplying a gas into the compartment of the capsule to assist in the removal of liquid from the capsule. 7. The method according to claim 6, wherein the gas is supplied into the compartment from the exterior of the capsule through the gas inlet without passing through the microporous membrane. 8. The method according to claim 7, wherein the gas is supplied upstream of the outlet nozzle communicating with the compartment. 9. The method according to claim 6, wherein the supplying of the gas is carried out at least until the compartment of the capsule is emptied from liquid. 10. In combination, a capsule and a device for delivering a nutritional composition from a capsule, the combination comprising the capsule according to claim 1, and a device for supplying liquid to the capsule for preparation of the nutritional composition; the device comprising a liquid injector, and a gas injector for injecting gas into the capsule which is distinct and spatially distant from the liquid injector so that gas is supplied in the capsule through the gas inlet of the capsule which is spatially distant from a liquid inlet of the capsule to assist in the removal of liquid from the capsule. 11. The capsule of claim 1, wherein the microporous membrane has a pore size of less than 0.4 microns, a thickness of less than 500 microns, and is made of polyethersulfone, cellulose acetate, cellulose nitrate, polyamide or combinations thereof. 12. The capsule of claim 1, wherein the capsule comprises a bottom wall that includes a nutritional production outlet conduit opposite to the top membrane, and wherein the gas inlet comprises an opening through the inlet wall that intersects with the liquid conduit and is arranged so that gas entering the capsule body will bypass the microporous membrane, and further wherein both a liquid inlet and the gas inlet are closed by the top membrane. 13. The capsule of claim 12, wherein the liquid and gas inlets are selectively openable when the top membrane is perforated at the liquid and gas inlets, respectively, with the top membrane being sealed separately around the liquid inlet and gas inlet by seals. 14. The capsule of claim 1 wherein the casing is formed of two parts which are welded or clipped together while pinching the microporous membrane at a circumference of the microporous membrane, the compartment comprises a compartment opening, the filtering surface is smaller than the compartment opening, and the side wall of the body has a top edge that defines the compartment opening, the side wall including weakened lines oriented to promote compression of the body of the capsule in an axial direction. 15. The capsule according to claim 4, wherein the inlet wall of the casing comprises a liquid inlet and the gas inlet at different positions on the inlet wall relative to each other, the liquid inlet emerges into a first side of the inner compartment in which the microporous membrane is inserted, the liquid conduit extends from a second side of the inner compartment to the outlet nozzle, and the microporous membrane is located between the first and second sides of the inner compartment. 16. The capsule according to claim 15, wherein the gas inlet merges with the liquid conduit at a point between where the liquid conduit begins at the second side of the inner compartment of the casing and where the liquid conduit ends at the outlet nozzle.
