A coffee filter holder includes a funnel wall, a substantially flat bottom wall having an outer edge and a coffee brew outlet, a drip-stop valve assembly that can be brought in an opened and a closed condition. The drip-stop valve assembly includes a valve member mounted on a blade spring connected to the bottom wall, and an actuator lever slideably connected to the bottom wall. The actuator lever includes an integral piece of sheet material with a first end that extends beyond the outer edge of the bottom wall so as to be engageable by hand and having a second end positioned under the substantially flat bottom wall to engage the valve member carrier to bring valve member from the opened position to the closed position and vice versa.

A coffee filter holder including: a funnel wall defining an upper edge bounding an inlet opening and defining a lower edge;a bottom wall having an outer edge, the bottom wall connected to the lower edge of the funnel wall and having a coffee brew outlet; anda drip-stop valve assembly that can be brought in an opened and a closed condition, the drip-stop valve assembly including: a valve member that, in the closed condition of the drip-stop valve assembly, is in a closed position wherein the valve member closes off the coffee brew outlet, wherein the valve member, in the opened condition of the drip-stop valve assembly, is in an opened position that allows coffee extract to be discharged from the coffee brew outlet;a blade spring having a first end and a second end opposite the first end, the blade spring being connected to the bottom wall adjacent the first end of the blade spring and the valve member connected to the blade spring adjacent the second end of the blade spring; andan actuator lever slideably connected to the bottom wall and being in sliding engagement with the blade spring and configured to bring valve member from the opened position to the closed position and vice versa, the actuator lever comprising an integral piece of sheet material including a first flat part extending parallel to the bottom wall, the first flat part having a first end that extends beyond the outer edge of the bottom wall so as to be engageable by hand and having a second end that is positioned under the substantially flat bottom wall. 2. The coffee filter holder according to claim 1, wherein the integral piece of sheet material of the actuator lever includes: a second flat part connected to the second end of the first part via a sharp bend; anda slit in the piece of sheet material at the bend and parallel to the bend;wherein the blade spring extends through the slit. 3. The coffee filter holder according to claim 1, wherein the bottom wall includes: a first rim extending downwardly from the bottom wall;a first guiding slit being provided in the first rim and extending parallel to the bottom wall;wherein the actuator lever extends through the first guiding slit so that it is slideable through the first guiding slit. 4. The coffee filter holder according to claim 1, including: a bracket that is connected with the bottom wall so that between the bracket and the bottom wall a second guiding slit is formed;wherein the integral piece of sheet material of the actuator lever extends through the second guiding slit so that it is slideable through the second guiding slit. 5. The coffee filter holder according to claim 1, wherein the bottom wall includes: a brew outlet rim surrounding the brew outlet and extending downwardly from the bottom wall, the brew outlet rim having a free end that forms a seat for the valve member;wherein the piece of sheet material of the actuator lever includes a slotted hole having a width that is equal to or slightly larger than the external diameter of the brew outlet rim;a length that defines the end positions of the sliding movement of the actuator leverwherein the brew outlet rim extends through the slotted hole. 6. The coffee filter holder according to claim 1, wherein the piece of sheet material of the actuator lever is a piece of sheet metal. 7. The coffee filter holder according to claim 1, wherein the blade spring includes a bend so that the valve member is biased into the open position. 8. A coffee maker including: a housing;a filter holder support bracket connected to the housing; anda filter holder according to claim 1. 9. A coffee maker including: a housing;a filter holder support bracket connected to the housing; anda filter holder according to claim 2. 10. A coffee maker including: a housing;a filter holder support bracket connected to the housing; anda filter holder according to claim 3. 11. A coffee maker including: a housing;a filter holder support bracket connected to the housing; anda filter holder according to claim 4. 12. A coffee maker including: a housing;a filter holder support bracket connected to the housing; anda filter holder according to claim 5. 13. A coffee maker including: a housing;a filter holder support bracket connected to the housing; anda filter holder according to claim 6. 14. A coffee maker including: a housing;a filter holder support bracket connected to the housing; anda filter holder according to claim 7. 15. A coffee filter holder including: a funnel wall defining an upper edge bounding an inlet opening and defining a lower edge;a bottom wall having an outer edge, the bottom wall connected to the lower edge of the funnel wall and having a coffee brew outlet; anda drip-stop valve assembly that can be brought in an opened and a closed condition, the drip-stop valve assembly including: a valve member that, in the closed condition of the drip-stop valve assembly, is in a closed position wherein the valve member closes off the coffee brew outlet, wherein the valve member, in the opened condition of the drip-stop valve assembly, is in an opened position that allows coffee extract to be discharged from the coffee brew outlet;a blade spring having a first end and a second end opposite the first end, the blade spring being connected to the bottom wall adjacent the first end of the blade spring and the valve member connected to the blade spring adjacent the second end of the blade spring, the blade spring having a bent configuration for biasing the valve member in the opened position in which the valve member is spaced apart from the coffee brew outlet; andan actuator lever slideably connected to the bottom wall and being in sliding engagement with the blade spring, the actuator lever comprising an integral piece of sheet material including a first flat part extending parallel to the bottom wall, the first flat part having a first end that extends beyond the outer edge of the bottom wall so as to be engageable by hand and having a second end that is positioned under the substantially flat bottom wall, the actuator lever including a slit in the piece of sheet material, the blade spring extending through the slit thereby forming an engagement between the actuator lever and the blade spring,wherein a sliding movement of the actuator lever along the bottom wall displaces the slit relative to the blade spring thereby moving the second end of the blade spring towards and away from the coffee brew outlet so as to bring valve member between an opened and closed position.
