Method of making a beverage from powdered material in a sealed capsule
First Claim
1. A method of making a beverage from powdered material in a cup-shaped sealed capsule (2), the method comprising the steps of inserting a said sealed capsule (2) between pressurized-hot-water dispensing means (11) and a cup (42) aligned with the dispensing means (11) along a horizontal axis (9), the insertion step being carried out by feeding the sealed capsule (2) downwards along an inlet conduit (52) into a first seat (67) defined between two elastically deformable jaws (63), and applying downward thrust to the sealed capsule (2) inside the first seat (67) to part the two jaws (63) and transfer the sealed capsule (2) from the first seat (67) to a second seat (68) coaxial with said axis (9) and also defined by said two jaws (63);
- and the method further comprising the steps of piercing a sealing wall (6) fitted integrally to an outer annular flange (4) of the sealed capsule (2) by applying an axial force to said flange (4) and pushing the sealed capsule (2), still coaxial with said axis (9), axially against a first piercing device (21) carried by the dispensing means (11); and
piercing an end wall (5) of the sealed capsule (2) opposite to the sealing wall (6) by applying axial compression to the sealed capsule (2) to push the end wall (5) against a second piercing device (44) carried by the cup (42);
the axial compression being applied only after feeding pressurized hot water into the sealed capsule (2) through the pierced sealing wall (6).

Abstract
In a process employing a coffee machine, a sealed capsule is fed with a certain amount of axial clearance into a cup aligned along a horizontal axis with a pressurized-hot-water sprinkler, and is moved towards the sprinkler to press an annular flange of the sealed capsule in fluidtight manner against the sprinkler, to pierce a front sealing wall of the sealed capsule by means of a first piercing device, to feed pressurized hot water through the sealing wall to expand the sealed capsule axially and eliminate the axial clearance, and to bring an end wall of the sealed capsule into fluidtight contact with a second piercing device, and pierce the end wall against the second piercing device, so that coffee flows out through the second piercing device.
