The holder capable of being coupled to and decoupled from the support. Wherein the holder is rotatable about a first axis of the clamping mechanism between: i) a first position, in which the holder is able to be coupled to or decoupled from the support and the holder and clamp are relatively spaced apart in the direction of the first axis; and ii) a second position in which the holder is retained to the support and the holder and clamp are relatively close to one another in the direction of the first axis such that a beverage cartridge held in use in the holder is clamped between the holder and the clamp. Wherein the clamping mechanism further comprises an inlet piercer for forming an inlet in the beverage cartridge. Wherein the inlet piercer forms part of or is coupled to, the clamp and is able to rotate with the holder about the first axis. ## Claims ### Claim at position 1 1: A clamping mechanism for a beverage preparation machine comprising: a support; a holder for a beverage cartridge; and a clamp; the holder capable of being coupled to and decoupled from the support; wherein the holder is rotatable about a first axis of the clamping mechanism between: i) a first position, in which the holder is able to be coupled to or decoupled from the support and the holder and clamp are relatively spaced apart in the direction of the first axis; and ii) a second position in which the holder is retained to the support and the holder and clamp are relatively close to one another in the direction of the first axis such that a beverage cartridge held in use in the holder is clamped between the holder and the clamp; wherein the clamping mechanism further comprises an inlet piercer for forming an inlet in the beverage cartridge, wherein the inlet piercer forms part of, or is coupled to, the clamp and is able to rotate with the holder about the first axis. ### Claim at position 2 (depends on 1) 2: A clamping mechanism as claimed in claim 1 wherein the support comprises a fixed support part and a rotatable support part; the holder being able to be coupled to or decoupled from the rotatable support part. ### Claim at position 3 3: A clamping mechanism as claimed in claim.2 wherein: i) the clamp is coupled to the rotatable support part so as to be rotational fixed thereto but able to move relative thereto in the direction of the first axis; ii) the rotatable support part is rotatable relative to the fixed support part but fixed relative thereto in the direction of the first axis; and iii) the clamp is coupled to the fixed support part so as to be movable relative thereto both in the direction of the first axis and rotationally. ### Claim at position 4 (depends on 2) 4: A clamping mechanism as claimed in claim 2 wherein: i) the rotatable support part comprises one or more axial guide slots orientated in the direction of the first axis and the clamp comprises one or more pegs which are slidingly received in the one or more axial guide slots; ii) the fixed support part comprises one or more curved guide slots in which the one or more pegs of the clamp are slidingly received. ### Claim at position 5 (depends on 1) 5: A clamping mechanism as claimed in claim 1 wherein the holder is rotatable about the first axis in a plane substantially perpendicular to the first axis and wherein during rotation between the first and second positions the holder remains in said plane without moving along the first axis. ### Claim at position 6 (depends on 1) 6: A clamping mechanism as claimed in claim 1 wherein the holder and clamp are coupled to the support such that on rotation of the holder between the first and second positions the clamp is moved in the direction of the first axis. ### Claim at position 7 (depends on 1) 7: A clamping mechanism as claimed in claim 1 wherein the clamping mechanism further comprises a beverage cartridge support which forms a part of, or is coupled to, the holder; the beverage cartridge support being movable between: i) a loading position in which, with the holder coupled to the support in the first position, the beverage cartridge support is inclined relative to a plane substantially perpendicular to the first axis; and ii) a clamped position in which, with the holder coupled to the support in the second position, the beverage cartridge support is in the plane substantially perpendicular to the first axis. ### Claim at position 8 (depends on 1) 8: A clamping mechanism as claimed in claim 1 wherein the inlet piercer is off-set from the centre of the clamp such that the inlet piercer follows an arc path as the clamp rotates about the first axis. ### Claim at position 9 (depends on 1) 9: A clamping mechanism as claimed in claim 1 wherein, the clamping mechanism further comprises an outlet piercer for forming an outlet in the beverage cartridge, wherein the outlet piercer forms part of, or is coupled to, the holder so as to rotate with the holder between the first and second positions. ### Claim at position 10 10: A method of clamping a beverage cartridge in a beverage preparation machine comprising the steps of: inserting the beverage cartridge into a holder; coupling the holder to a support; rotating the holder and inlet piercer about a first axis; said rotation causing the holder and a clamp to move relatively closer to one another in the direction of the first axis so as to engage the beverage cartridge with the clamp and so clamp the cartridge between the clamp and the holder; and piercing an inlet in the cartridge using an inlet piercer which rotates with the clamp about the first axis. ### Claim at position 11 (depends on 10) 11: A method as claimed in claim 10 wherein the holder is rotated in a plane substantially perpendicular to the first axis and wherein during rotation the holder remains in said plane without moving along the first axis. ### Claim at position 12 (depends on 10) 12: A method as claimed in claim 10 wherein the beverage cartridge is initially supported in the holder in an inclined orientation such that with the holder coupled to the support the beverage cartridge is inclined relative to a plane substantially perpendicular to the first axis; wherein on rotation of the holder the clamp forces the beverage cartridge to rotate about a second axis perpendicular to the first axis so to lie in the plane substantially perpendicular to the first axis. ### Claim at position 13 (depends on 12) 13: A method as claimed in claim 12 wherein the holder further comprises an outlet piercer, the inlet piercer and outlet piercer piercing opposite sides of the beverage cartridge, the holder comprising an inlet piercer. ### Claim at position 14 14: A clamping mechanism for a beverage preparation machine comprising: a support; a holder for a beverage cartridge; and a clamp; the holder capable of being coupled to and decoupled from the support and comprising a beverage cartridge support; the holder being rotatable about a first axis of the clamping mechanism between: i) a loading position in which the holder and clamp are relatively spaced apart in the direction of the first axis wherein the beverage cartridge support of the holder is inclined relative to a plane substantially perpendicular to the first axis; and ii) a clamped position in which the holder and clamp are relatively close to one another in the direction of the first axis wherein the beverage cartridge support has been moved into the plane substantially perpendicular to the first axis. ### Claim at position 15 (depends on 14) 15: A clamping mechanism as claimed in claim 14 wherein: i) the holder comprises a body having a base and a side wall so as to define a cavity; and ii) the beverage cartridge support is located within the cavity. ### Claim at position 16 (depends on 15) 16: A clamping mechanism as claimed in claim 15 wherein the beverage cartridge support is pivotally coupled to the holder so as to be rotatable between the loading and clamped positions. ### Claim at position 17 (depends on 14) 17: A clamping mechanism as claimed in claim 14 wherein the beverage cartridge support ie biased into the position in which it is inclined relative to the plane substantially perpendicular to the first axis. ### Claim at position 18 (depends on 14) 18: A clamping mechanism as claimed in claim 14 wherein the holder further comprises an outlet piercer extending upwardly from the base. ### Claim at position 19 (depends on 1) 19: A beverage preparation system comprising a beverage preparation machine and a beverage cartridge, wherein the beverage preparation machine comprises a clamping mechanism as claimed in claim 1. ### Claim at position 20 (depends on 14) 20: A beverage preparation system comprising a beverage preparation machine and a beverage cartridge, wherein the beverage preparation machine comprises a clamping mechanism as claimed in claim 14.
