FIELD: food engineering. SUBSTANCE: holder has rigid body with portion of granular, powder or similar microparticle material for obtaining of beverage by filtering, solving or infusing with hot water under pressure. Rigid body is composed of cylindrical hollow part with continuous side wall, inlet end wall with perforated central portion and opposed perforated outlet walls. Perforated inlet wall has external peripheral circular bead encircling central perforated portion for joining with heated plate of machine under the action of mechanical force to provide for supplying into detachable holder under hydraulic pressure through perforated central portion of end wall of hot water for producing beverage and discharging it through perforated outlet wall. Circular bead of inlet end wall is made from plastic material, which softens at temperature of heated conveying plate of machine for extracting and distributing hot beverages. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 6 cl, 4 dwg
