A filter-holder includes a cylindrical cup (1), a filtering chamber (4) defined by the inner side wall (5) of the cup and a perforated base (6) provided with a grille (7), a vessel (9) collecting the infusion placed underneath the grille (7) and provided with elements for evacuating the infusion (11
A filter-holder includes a cylindrical cup (1), a filtering chamber (4) defined by the inner side wall (5) of the cup and a perforated base (6) provided with a grille (7), a vessel (9) collecting the infusion placed underneath the grille (7) and provided with elements for evacuating the infusion (11), and at least two infusion, outlet pipes (15, 16). The filter-holder includes an infusion dispensing trough (10) placed beneath the vessel (9) which includes elements channelling (13, 35) the infusion flow towards the filter-holder outlet pipes. A selecting member (S1, S2) generates a relative rotational motion between the vessel (9) and the trough (10) to obtain an infusion flow either through one outlet pipes only (15), or through both outlet pipes (15, 16).

1. Filter-holder to be mounted on a coffee machine, comprising:a cylindrical cup provided with a sleeve; a filtration chamber delimited by an internal sidewall of the cup and a perforated bottom provided with a grille; a bowl to collect an infusion disposed below the grille of the perforated bottom
1. Filter-holder to be mounted on a coffee machine, comprising:a cylindrical cup provided with a sleeve; a filtration chamber delimited by an internal sidewall of the cup and a perforated bottom provided with a grille; a bowl to collect an infusion disposed below the grille of the perforated bottom and provided with infusion evacuation means and at least two outlet pipes for the infusion; a distribution pan for distributing the infusion disposed below the collection bowl and comprising channeling means for channeling the flow of the infusion toward the outlet pipes; and a selection member adapted to cause relative rotational movement between the bowl and the distribution pan between two positions: a two-cup position permitting selecting the channeling means which direct the flow of the infusion toward all the outlet pipes; and a one-cup position permitting selecting the channeling means which direct the flow toward a single outlet pipe. 2. The filter-holder according to claim 1, wherein the evacuation means comprise a tube located on the bottom of the bowl eccentrically, and the channeling means comprise a first zone located between the outlet pipes and delimited by a partition having two calibrated passages toward the outlet pipes, a second zone defined by the inlet opening of an outlet pipe, the selection member comprising a peripheral ring which drives an rotation the collection bowl via a disk between the two positions:the two-cup position, in which the tube of the bowl is located above the first zone of the distribution pan; and the one-cup position, in which the tube of the bowl is located above the second zone of the distribution pan. 3. The filter-holder according to claim 1, wherein the evacuation means comprise two openings located on opposite sides of a diagonal of the bowl, and the channeling means comprise two inclined planes whose intersection forms a summit ridge along a diagonal of the distribution pan, each inclined plane being provided in its lower portion with an opening which communicates with an outlet pipe, and the selection member drives in rotation the collection bowl via a shaft between the two positions:the two-cup position, in which each opening of the bowl is disposed above an inclined plane; and the one-cup position, in which the two openings of the bowl are located above a single inclined plane. 4. The filter-holder according to claim 1, wherein the perforated bottom is movable as to height; and the bowl comprises between its lower portion and the perforated bottom a stack of a crown and a counter crown that are coaxial and provided on their facing surfaces with an alternate series of ramps and staged regions such that the rotation of the selection member gives rise to a relative rotational movement between the crown to vary the height of the perforated bottom in the cup.5. The filter-holder according to claim 4, wherein the crown forms a portion of the lower surface of the perforated bottom, and the counter crown forms a portion of the upper surface of the distribution pan.6. The filter-holder according to claim 1, wherein the perforated bottom is movable as to height, and the bottom of the cup comprises a tubular element provided with an upper region and a lower region, the selection member fixed to the perforated bottom comprises a cam adapted to be held bearing against said tubular element via a resilient means in two positions:a first position in which the cam bears against the lower region of the tubular element; and a second position in which the cam bears against the upper region of the tubular element. 7. The filter-holder according to claim 4, wherein the selection member places the perforated bottom in the two positions:the two-cup position, in which the perforated bottom occupies a lower position; and the one-cup position, in which the perforated bottom occupies an upper position. 8. The filter-holder according to claim 1, wherein the perforated bottom is movable as to height; the filter-holder further comprising an ejection member connected to the perforated bottom via a shaft and held in a rest position by a resilient return means; said ejection member being movable along the vertical axis of the cup such that pressure on the latter raises the perforated bottom to facilitate ejection of grounds.9. The filter-holder according to claim 3, wherein the perforated bottom is movable as to height, and the bottom of the cup comprises a tubular element provided with an upper region and a lower region, the selection member fixed to the perforated bottom comprises a cam adapted to be held bearing against said tubular element via a resilient means in two positions:a first position in which the cam bears against the lower region of the tubular element; and a second position in which the cam bears against the upper region of the tubular element. 10. The filter-holder according to claim 5, wherein the selection member places the perforated bottom in the two positions:the two-cup position, in which the perforated bottom occupies a lower position; and the one-cup position, in which the perforated bottom occupies an upper position. 11. The filter-holder according to claim 6, wherein the selection member places the perforated bottom in the two positions:the two-cup position, in which the perforated bottom occupies a lower position; and the one-cup position, in which the perforated bottom occupies an upper position.
