Capsule holder for a beverage preparation machine

1. A capsule holder for holding a closed capsule in a beverage preparation machine, the capsule containing a beverage precursor ingredient, the beverage preparation machine being able to inject a fluid under pressure through a top membrane of the capsule to an inside of the capsule such that the fluid and the precursor ingredient mix to make a beverage, the capsule holder comprising:

a cup-shaped body adapted to retain and hold the capsule, the cup-shaped body comprises a dispensing hole through a bottom wall of the capsule holder opposite from and co-axial with an opening in the capsule holder through which the capsule is inserted into the capsule holder;

a rotationally movable handle;

a guide member for removably inserting the capsule holder within the beverage preparation machine; and

a pressure-releasing member for releasing fluid pressure inside the capsule, the pressure-releasing member comprising a piercer adapted to pierce at least one channel through a sidewall of the capsule, the piercer comprising a pin element movably linked to the rotationally movable handle through a cam element attached to or integrally formed with the rotationally movable handle, such that the pin element is slidable substantially perpendicular relative to a capsule sidewall surface when a rotation movement is applied to the rotationally movable handle, and the pin element movable through a first internal surface of the cup-shaped body between (i) a retracted position wherein the pin element does not protrude from the first internal surface of the cup-shaped body of the capsule holder and (ii) an extended position wherein the pin element protrudes from the first internal surface of the cup-shaped body to be able to perforate the at least one channel through the sidewall of the capsule, the pin element is perpendicular to the first internal surface, the cup-shaped body further comprises a second internal surface that together with the first internal surface defines part of a compartment in the cup-shaped body that receives the capsule, the dispensing hole opens into the compartment through the second internal surface, the first internal surface is located below a top of the capsule holder, the first internal surface is adjacent to the sidewall of the capsule in the retracted position and the extended position of the pin element, and the second internal surface is adjacent to a bottom end of the capsule in the retracted position and the extended position of the pin element.

2. The capsule holder of claim 1 , wherein the pressure-releasing member is automated and actuated by the beverage preparation machine.

3. The capsule holder of claim 1 , wherein the pressure-releasing member is manually operated by a user.

4. The capsule holder of claim 1 , wherein the cam element is spring-mounted, such that when no force is applied to the rotationally movable handle, the pin element is in the retracted position.

5. The capsule holder of claim 1 , wherein the piercer is located adjacent to the sidewall of the capsule.

6. The capsule holder of claim 1 , further comprising a spring that abuts an external surface of a side wall of the cup-shaped body and biases the pin element toward the retracted position.

7. The capsule holder of claim 1 , wherein the dispensing hole is configured to (a) open when the beverage preparation machine injects the fluid to the inside of the capsule and (b) close when the beverage preparation machine stops injecting the fluid.
