Capsule and method for preparing a food liquid by centrifugation

A single-use capsule for preparing a food liquid in a beverage production device from a food substance contained in the capsule by introducing water in the capsule and passing water through the substance using the centrifugal forces for producing the food liquid which is centrifuged peripherally in the capsule relatively to a central axis of the capsule corresponding to an axis of rotation during the centrifugation in the device, the capsule comprising:

• an upper wall comprising a top membrane and an internal rigid lid, with the internal lid comprising or forming at least part of a continuous annular collecting recess, with the collecting recess being closed by the top membrane to form a first annular peripheral outlet region in which the top membrane is perforable and dedicated for providing outlets for the release of the liquid with the internal lid comprising a central opening closed by the top membrane to form a second region which is a central region dedicated for being pierced by a water injector of a liquid food preparation device, and with the upper wall comprising the internal lid placed below the top membrane to reinforce the top membrane between the first and second region so that the upper wall is non-perforable between the first and second regions;
• a lower wall;
• and
• a widening side wall connecting the upper and lower walls,
• wherein the lower wall, widening side wall and the internal lid define an enclosure having a rim onto which the top membrane is mounted and the enclosure contains a predetermined amount of food substance;
• and
• wherein the widening side wall and lower wall form a cup-shaped body with a flange-like rim onto which the top membrane is sealed.

A single-use capsule configured for preparing a food liquid in a beverage production device from a food substance contained in the capsule by introducing water into the capsule along a central axis thereof and passing water through the substance using the centrifugal forces generated by rotating the capsule about the central axis in the device, the capsule comprising:

• an upper wall comprising a top membrane and an internal rigid lid, with the internal lid comprising or forming at least part of a continuous annular collecting recess, with the collecting recess being closed by the top membrane to form a first annular peripheral outlet region in which the top membrane is perforable to provide outlets for the release of the liquid with the internal lid comprising a central opening closed by the top membrane to form a second region which is a central region that is pierceable to provide an inlet for the introduction of water;
• the upper wall comprising the internal lid placed below the top membrane to reinforce the top membrane between the first and second region so that the upper wall is non-perforable between the first and second regions;
• a lower wall;
• and
• a side wall connecting the upper and lower walls,
• wherein the lower wall, side wall and the internal lid define an enclosure having a rim onto which the top membrane is mounted and the enclosure contains a predetermined amount of food substance.
