Abstract:
A chamber for a cartridge containing a beverage extract and including a bottom, sidewall and top sealed to the sidewall along a peripheral rim, said chamber comprising:a cup shaped housing having a sidewall and a bottom wall with an upwardly projecting apertured probe defining a liquid outlet;a platform overlying said bottom wall, said platform having an opening aligned with said apertured probe and being provided with an upwardly extending ejection arm, said platform being movable between a raised position at which said platform wall is above said probe and said ejection arm projects above said housing, and a lowered position at which said probe projects through said opening in said platform and said ejection arm is retracted into said housing, said housing being configured and dimensioned to receive said cartridge with said peripheral rim overlying said ejection arm;spring means for resiliently urging said platform into said raised position;a lid overlaying said housing, said lid having a downwardly projecting apertured probe defining a liquid inlet; andmeans for manipulating said lid between a ready position spaced above said housing, and a beverage brewing position where said lid applies an axial positioning force to the peripheral rim that urges the cartridge and said platform downwardly, thereby causing said downwardly and upwardly apertured probes to pierce the cartridge and thereby place said liquid inlet in communication with said liquid outlet via the interior of said cartridge.
