Capsule for preparing a beverage or liquid food and system using brewing centrifugal force

摘要

A capsule for preparing a beverage or liquid food from a substance, in a centrifugal brewing unit, by passing water through the substance contained in the capsule by using brewing centrifugal forces. The capsule includes an enclosure containing a predetermined dose of substance, an opening member which opens the capsule under the centrifugal effect to allow the brewed liquid to leave the capsule. The capsule may also include externally driving the capsule in a centrifugal brewing device wherein the capsule includes a structure configured to offer resistance to torque during rotation of the capsule for maintaining the capsule in a reference rotational position.

主权项

1. A capsule for preparing a beverage or liquid food in a centrifugal brewing device from a food substance contained in the capsule by passing water through the substance using centrifugal brewing forces, the capsule comprising:
an enclosure containing a predetermined dose of substance, the enclosure comprising a body for holding the food substance, the body having an upper rim, and a lid or membrane for closing the body at the upper rim, and means for engaging the capsule to external rotational driving means of a centrifugal brewing device, the engaging means comprising a gripping structure of a toothed structure or a series of protrusions or recessed elements on an outer surface of the enclosure, with the gripping structure having a shape that is complementary to an engaging structure of the driving means so that the capsule gripping structure locks into the engaging structure of the driving means to fulfil both a gearing function for driving the capsule at high speeds in rotation and a safety function for ensuring that only capsules with the gripping structure can be used and brewed successfully in the centrifugal brewing device, wherein the engaging means also offers resistance to torque during rotation of the capsule for maintaining the capsule in a reference rotational position.
