CAPSULE FOR PREPARING BEVERAGE Russian patent published in 2016 - IPC B65D85/804 

FIELD: food industry.

SUBSTANCE: capsule comprises cup-shaped body (2) closed on upper side by lid (3). Capsule has a plurality of infusion chambers (7, 8), each provided with an area for inlet of a water flow and an area for outlet of infusion. Brewing chambers are concentric and are fluidically sealed from each other. Housing (2) has at least one intermediate wall (6), dividing inner part of housing into brewing chambers (7, 8), located inside housing and is made integral with wall (5) of base, from which it extends parallel with side wall (4). Wall of base has a plurality of first through holes (13, 14). Plurality of annular protrusions (15, 16), protruding from outer surface of base and extending downward, separates some of said first holes (13) from other of said first holes (14) so that they form a plurality of regions for discharge of infusions for each one of brewing chambers. Cover has a plurality of second through holes (25, 26) and a plurality of bulges (18 and 21), separating second holes (25) from other second holes (26) so as to form a plurality of areas for inlet of water flow into brewing chamber. Annular bulge (18) is made along peripheral edge of cover so that with cover it adjoins annular protrusion (24) on inner surface of side wall (4) near its top end. Bulge (21) is a concentric annular thickening (18) so that with cover (3) it ends near upper end of intermediate wall (6).

EFFECT: invention provides reliable tight connection between chambers.
