The present invention is directed to a capsule (1) for use in a beverage preparation machine, said capsule comprising : (i) lateral walls (2), a pierceable injection wall (3) adapted to be pierced by fluid injection means (4) of the machine, and a dispensing wall (5) adapted to dispense said beverage, that delimit a closed internal volume, (ii) a flexible fluid distributor wall (7), that is located inside the closed volume of the capsule, at a distance below the pierceable wall (3) so as to separate: - a headspace compartment (8) between the pierceable wall (3) and said fluid distributor wall (7) which is able to accommodate the injection means during injection of the fluid, and - an ingredient compartment (9) located between said fluid distributor wall (7) and said dispensing wall (5), containing a bed of non-soluble beverage ingredient particles, characterized in that the headspace compartment (8) contains a superabsorbent polymer (10) able to absorb a quantity of the injected fluid, and swell so as to fill the headspace compartment (8) and exert a pressure force onto the surface of the fluid distributor wall (7) to prevent substantial movement of ingredient particles while said fluid traverses said ingredient. |
