Abstract:
1. 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; and 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 capsule is designed so that the central inlet portion to provides a liquid tightness between the liquid inlet and the surface of an injection needle of the beverage production device preventing liquid from leaking from inside toward outside of the capsule; the capsule is designed to allow centrifuged liquid to traverse the upper wall in the peripheral outlet portion; wherein the central inlet portion comprises a tightness-producing layer and, the peripheral outlet portion presents at least an area without such tightness-producing layer; and wherein the tightness-producing layer is obtained by using a structure selected from the group consisting of a resilient or soft material comparatively thicker than the same material in the peripheral outlet portion, a more resilient or softer thickness of material than the material thickness in the peripheral outlet portion and a fibrous or foam material localized in the central inlet portion, to create in the central inlet portion a liquid tightness by contact of such material with the outer surface of an injection needle of the device when introduced through the upper wall in the central inlet portion.
