PREPARING A BEVERAGE BY CENTRIFUGATION

Use of a receptacle for a device configured to prepare a beverage from a beverage ingredient contained in the receptacle (17) by driving the receptacle in centrifugation comprising:- a holding part (16) arranged for holding the receptacle in a position enabling it to be driven in rotation along a longitudinal axis of rotation (I),- a liquid interfacing part (8) arranged for supplying water in the receptacle and/or extracting the beverage from the receptacle,- a collecting part (44) for collecting the beverage obtained by the interaction between the ingredient and water in the receptacle,wherein the holding part and liquid interfacing part (8, 16) are connected together by connection means in such a manner that these parts (8, 16) rotate together with the receptacle during centrifugation,wherein the connection means comprise at least a first engaging surface (48; 86) of the holding part (16) and a second engaging surface (23; 87) of the liquid interfacing part (8) engaged in contact together during connection in a manner preventing the holding part (16) and the liquid interfacing part (8) from moving away from each other, at least in the axial direction of rotation (I), and the connection means further comprising at least one mass of inertia (20, 21, 31; 80) arranged to be moveably connected to at least one of the parts (8, 16) with at least one degree of freedom in a least one radial direction for enabling the engagement forces to increase between the two engaging surfaces as a result of the increase of the centrifugal forces.
