Patent ID: 8919242

Claim:
A liquid food preparation system for preparing a liquid food from a food substance comprising a device and a capsule removably insertable in the device by passing water through the substance in the capsule, which system comprises: a closed capsule comprising a peripheral wall and having a central axis, a capsule holder for holding the capsule in the device, a water injection head for injecting water in the capsule comprising a rotary engaging member for engaging the capsule and forming a secure association between the capsule and the capsule holder, and a water injector in fluid association with the water injection head and arranged for introducing water into the capsule, opening members placed relatively offset to the central axis of the capsule holder and protruding from an interior surface of the device adjacent to an upper portion of the capsule, and a rotational driving assembly comprising a rotary motor driving the capsule in centrifugation, and wherein the opening members are elements; and are configured relative to the peripheral wall of the capsule in the device to create a plurality of liquid delivery outlets in the peripheral wall of the capsule when a liquid within the capsule exerts a pressure against the peripheral wall of the capsule that exceeds a threshold pressure and forces the peripheral wall to be penetrated by the opening members to form the delivery plurality of liquid outlets.
