Capsule for preparing a beverage with enhanced sealing means

摘要

The present invention relates to a capsule (1) for containing beverage ingredients intended to produce a beverage in a beverage preparation device (20) upon liquid injection into the capsule and by rotating the capsule around its central axis in the device (20), the capsule (1) comprising: a side wall (2a), a bottom wall (2b) and a flange-like rim (2c), an upper wall (3) attached to the flange-like rim (2c) and/or the side wall (2b) of the capsule (1), the upper wall (3) comprising a central liquid inlet (4) and peripheral outlet apertures (5), wherein the upper wall (3) further comprises an outwardly protruding sealing member (6) which is arranged at an annular portion (3a) of the upper wall (3) between the central liquid inlet (4) and the peripheral outlet apertures (5), and which is designed to at least significantly hinder, preferably prevent liquid from flowing at the outside of the capsule (1) from the liquid inlet (4) to the outlet apertures (5) when the sealing member is engaged by the beverage preparation device (20) and, wherein the sealing member (6) is located radially distanced from the liquid inlet (4).

主权项

1. A capsule for containing beverage ingredients intended to produce a beverage in a beverage preparation device upon liquid injection into the capsule and by rotating the capsule around a central axis of the capsule in the beverage preparation device, the capsule comprising:
a body comprising a side wall, a bottom wall and a flange-like rim; and an upper wall attached to the flange-like rim and/or the side wall of the capsule, the upper wall and the body enclosing an ingredient compartment for the beverage ingredients, the upper wall comprising a central liquid inlet, peripheral outlet apertures, and an outwardly protruding sealing member, the central liquid inlet forming a circular aperture that communicates with the ingredient compartment, the central liquid inlet configured to accommodate a liquid injection member therethrough, the outwardly protruding sealing member arranged at an annular portion of the upper wall between the central liquid inlet and the peripheral outlet apertures, and designed to at least significantly hinder liquid from flowing at an outside of the capsule from the central liquid inlet to the peripheral outlet apertures when the outwardly protruding sealing member is engaged by the beverage preparation device, the upper wall being free of apertures between the outwardly protruding sealing member and the central liquid inlet, the upper wall is in recess relative to the flange-like rim and the outwardly protruding sealing member, and the outwardly protruding sealing member located radially distanced from the central liquid inlet.
