First Claim
Patent Images
1. A chamber for a cartridge containing a beverage extract, said chamber comprising:
- a 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 the cartridge with the cartridge mounted for movement in unison with said ejection arm;
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; and
means for manipulating said lid between a ready position spaced above said housing, and a beverage brewing position where said lid applies a positioning force urging the cartridge and said platform downwardly, causing said downwardly and upwardly projecting apertured probes to pierce the cartridge and place said liquid inlet in communication with said liquid outlet via the interior of the cartridge.

Abstract
A cup shaped holder is internally provided with an ejection mechanism which serves to automatically dislodge a spent beverage cartridge from an upwardly extending piercing member when the lid is opened at the end of a brewing cycle. In addition, the holder is mounted on externally protruding trunnions for pivotal movement between an upright brewing position and a partially inverted position to eject the dislodged cartridge from the holder into an underlying receptacle. The lid has a dependency arm that coacts with a pawl on the holder trunnions to automatically manipulate the holder to eject the cartridge.

A) said housing sidewall comprises: i) an exterior surface that includes a pair of radially outwardly extending trunnions that pivotally support said chamber;
ii) a first pawl attached to said housing sidewall, wherein said first pawl is engaged to cause said housing to pivot about said pair of radially outwardly extending trunnions and discharge the cartridge from said chamber;
iii) a second pawl attached to said sidewall, wherein said second pawl is engaged to limit the rotational travel of said chamber about said trunnions; and
B) said lid further comprises means for engaging said first and second pawls to pivot said chamber in order to discharge the cartridge from said chamber.

5. A beverage filter cartridge holder that receives a beverage filter cartridge containing a beverage extract, and positions and pierces the cartridge establishing a liquid flow path through the extract to provide a brewed beverage, said beverage filter cartridge holder comprising:
-
a base surface that includes a base opening coaxial with an upwardly extending hollow piercing member secured to said base surface;
a slidable cartridge platform having a bore formed therein coaxial with said hollow piercing member to allow said hollow piercing member to pass through said slidable cartridge platform;
a spring located between said base surface and said slidable cartridge platform;
a cartridge ejection arm having a first axial end connected with said slidable cartridge platform and a second axial end; and
a sidewall extending axially from said base surface and including an interior surface that defines a chamber sized to receive the beverage filter cartridge, wherein said interior surface includes a channeled axial passage that engages said cartridge ejection arm allowing said slidable cartridge platform to axially move deeper into said holder in response to a positioning force, wherein when the beverage filter cartridge is placed into said beverage filter cartridge holder, a radially outwardly protruding lip of the beverage filter cartridge rests on said second axial end of said cartridge ejection arm extending axially outside said beverage filter cartridge holder, and when the positioning force is applied to the radially outwardly protruding lip against said spring, said slidable cartridge platform moves downward causing said hollow piercing member to extend through said bore and pierce a bottom surface of the beverage filter cartridge to provide an exit flow path for the brewed beverage through said base opening. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A cartridge holder that receives a cartridge containing a beverage extract, and positions and pierces the cartridge to establish a liquid flow path through the beverage extract to provide a brewed beverage, said cartridge holder comprising:
-
a base surface that includes a base opening coaxial with an upwardly extending hollow piercing member secured to said base surface;
a slidable cartridge platform having a bore formed therein coaxial with said upwardly extending piercing member to allow said hollow piercing member to extend through said slidable cartridge platform;
a cartridge ejection arm having a first axial end connected with said slidable cartridge platform and a second axial end extending outside a chamber;
a sidewall extending axially from said base surface and including an interior surface that defines said chamber sized to receive the cartridge, wherein said interior surface includes a channeled passage that engages said cartridge ejection arm allowing said slidable cartridge platform to axially move within said chamber; and
a resilient member located between said base surface and said slidable cartridge platform;
wherein when the cartridge is placed into said cartridge holder, a radially outwardly protruding lip of the cartridge rests on said second axial end of said cartridge ejection arm. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
