CAPSULE FOR THE PREPARATION OF A BEVERAGE BY CENTRIFUGATION WITH A SEALING FLANGE

摘要

A capsule (1) comprising •a side wall (2a), a bottom wall (2b), a mouth opening (2c) and a flange-like rim (2d) extending outwardly, and •an upper wall (3) attached to the flange-like rim (2d) and/or to the side wall (2a) and at least partially covering the mouth opening (2c) •the upper wall (3) comprising a central liquid inlet (6) for injection of liquid in the capsule and a peripheral portion of wall (3a) comprising outlet apertures (5) for beverage to leave the capsule and •an annular engagement portion (10) located at least between the peripheral portion (3a) and the inlet (6) and arranged to form an inwardly protruding inlet flange (7) by a predefined design or by deformation upon introduction of a dedicated injection member (20) of a beverage preparation device through the inlet (6); such inlet flange (7) providing a liquid-tight sealing interaction with the outer surface of the injection member (20).

主权项

1. A capsule for containing beverage ingredients for producing a beverage in a beverage preparation device upon liquid injection into the capsule and by rotating the capsule around its central axis in the device for forcing liquid through the beverage ingredients in the capsule causing beverage to leave the capsule at the periphery of the capsule, the capsule comprising:
a side wall, a bottom wall, a mouth opening and a flange-like rim extending outwardly; an upper wall attached to the flange-like rim and/or to the side wall and at least partially covering the mouth opening; the upper wall comprising a central liquid inlet for injection of liquid in the capsule and a peripheral portion of wall comprising outlet apertures for beverage to leave the capsule; and an annular engagement portion located at least between the peripheral portion and the inlet and arranged to form an inwardly protruding inlet flange by a predefined design or by deformation upon introduction of a dedicated injection member of a beverage preparation device through the inlet, the inlet flange providing a liquid-tight sealing interaction with the outer surface of the injection member.
