Abstract (en)

Device for rapidly obtaining coffee directly in a cup according to standards which are close to a leaching (percolation) of real ground coffee. The porous bag-filter device containing a mass of prepared ground coffee adapted to extraction by hot water circulating under force inside it, by virtue of successive external pressures and relaxations which are applied to the mass of coffee via its envelope acting as a filter for the mass of ground coffee (6) contained, is made globally and reversibly compressible by the addition of multiple particles which are themselves reversibly compressible, the said particles being uniformly distributed in the mass of ground coffee so that the hot liquid, sucked or forced back (4 and 5) through the pores (7) circulates under force through the greater part of the ground coffee (6). The device is intended particularly for rapidly obtaining coffee and/or plant-based beverages. <IMAGE>
