Capsule for the preparation of a beverage by centrifugation

Capsule for the preparation of a beverage from a substance contained in the capsule in a beverage production device by passing liquid through the substance using centrifugal forces for producing the beverage comprising an enclosure containing an amount of beverage substance, the enclosure comprising:

• a body comprising a side wall, a bottom wall, an opening and a flange-like rim,
• an upper wall attached to the flange-like rim of the body and covering the opening of the body;
• the upper wall comprises a central inlet portion and a peripheral outlet portion between the inlet portion and the flange-like rim, the peripheral outlet portion being opened or openable to allow beverage to leave the capsule under the centrifugal forces;
• the central inlet portion comprises a tightness-producing layer;
• and
• the peripheral outlet portion comprises an area without such tightness-producing layer.

• an upper wall attached to the flange-like rim of the body and covering the opening of the body;
• the upper wall comprises a central inlet portion and a peripheral outlet portion between the inlet portion and the flange-like rim;
• the upper wall comprises a membrane which can be perforated by a central needle of the device in the central portion and perforated by perforating members of the device in the peripheral portion;
• the upper wall comprises a tightness-producing layer extending both in the central and peripheral portions;
• the tightness-producing layer can be perforated by the central needle and is designed to provide a tightness between the needle and the central inlet perforated by the needle to prevent leakage of liquid from inside towards outside of the capsule around the needle;
• and
• the tightness-producing layer is designed to be perforable and/or porous to liquid to allow centrifuged liquid to exit the capsule through the outlet perforations created by the perforating members in the membrane.

Method for preparing a beverage, from a capsule containing a substance, received in a beverage production device, the capsule comprising an upper wall with a central inlet portion and a peripheral outlet portion;

• the method comprising:
• feeding water by an injection needle while creating liquid tightness between the central inlet portion and the surface of the needle;
• dispensing the beverage from the capsule by centrifugation through outlets in the peripheral outlet portion;
• and
• the capsule is designed in the central inlet portion to provide a liquid tightness between the liquid inlet and the surface of the needle to prevent liquid from leaking from inside toward outside of the capsule and the capsule is also designed to allow centrifuged liquid to traverse the upper wall in the peripheral outlet portion.
