Abstract
A coffee machine wherein a pressurized hot water sprinkler faces a dispenser cup housing a rigid sealed capsule closed by a deformable end wall; and wherein the dispenser cup has a piercing device for piercing the end wall of the sealed capsule, when the end wall is permanently deformed outwards, by means of a number of conical needles facing the sprinkler and housed inside the dispenser cup; each needle having a conical outer surface, an inner conduit, and at least one axial slit formed in the conical outer surface to connect the relative inner conduit, in use, to the inside of the sealed capsule through the relative end wall.

1) A coffee machine comprising a pressurized hot water sprinkler (4);
- a dispenser cup (7) facing said sprinkler (4) and movable with respect to the sprinkler (4) to and from an infusion position in which the dispenser cup (7) is fitted to said sprinkler (4), said dispenser cup (7) having a percolator spout (19), and a cavity (16) communicating with said percolator spout (19) and for housing a rigid sealed capsule (10) for a measure of ground coffee, the sealed capsule (10) being closed, at one end, by a sealing film (15) facing the sprinkler (4) in use, and, at the other end, by an end wall (12);
- a first piercing device (46) carried by said sprinkler (4) to pierce, in use, said sealing film (15);
- and a second piercing device (26) carried by said dispenser cup (7) to pierce, in use, said end wall (12) when the end wall (12) is permanently deformed outwards;
- characterized in that said second piercing device (26) comprises a plate (27) housed in a fixed position inside said cavity (16) to divide the cavity (16) into a first portion (28) for housing said sealed capsule, and a second portion (29) communicating with said percolator spout (19), and a number of conical needles (30) projecting from said plate (27) towards said sprinkler (4);
- each said needle (30) having a conical outer surface (31), an inner conduit (32) extending through said plate (27) to communicate with said second portion (29), and at least one opening formed through said conical outer surface (31) to connect said inner conduit (32) to said first portion (28).
