Claim 20:
21. The system according to claim 20, wherein the sealing member is deformable such that said projection fluid sealingly contacts at least a portion of the free contact end of the annular element if, during brewing, said free contact end of the annular element exerts a force F2 on the sealing member of the capsule, wherein F2 is in the range of 500-1500 N preferably in the range of 750-1250 N when the fluid pressure P2 in said enclosing member outside the capsule is in the range of 6-20 bar, preferably between 12 and 18 bar; and
wherein, in use, when the closing member of the beverage preparation device closes the enclosing member of the beverage preparation device at least the free contact end of the enclosing member of the beverage preparation device moves relative to the closing member of the beverage preparation device under the effect of the pressure of the fluid in the enclosing member of the beverage preparation device towards the closing member of the beverage preparation device for applying the maximum force between the flange of the capsule and the free contact end of the enclosing member of the beverage preparation device, wherein optionally the enclosing member comprises a first part and a second part wherein the second part comprises the free contact end of the enclosing member wherein the second part moves relative to the first part between a first and second position wherein the second part moves from the first position towards the second position in the direction of the closing member under the influence of fluid pressure in the enclosing member wherein optionally the force F1 is reached if the second part is in the first position with the fluid pressure P1 in the enclosing member and wherein optionally the force F2 is reached if the second part is moved towards the second position under the influence of the fluid pressure P2 in the enclosing member.
