ABSTRACT:
A device for separating coffee grounds from rinse water is disposed beneath a drain pipe of the coffee-making machine. This device comprises a tubular jacket having on the top side thereof an inlet opening for admitting rinse water containing coffee grounds. Detachably connected to one end of the jacket is a funnel-shaped, resilient end piece having a small aperture. On the underside of the jacket is a slot in which a strainer is inserted, through which rinse water but not coffee grounds can flow out of the jacket. Within the jacket there is a piston slidingly driven by a drive piston for pressing rinse water out of the coffee grounds. In order for the coffee grounds to leave the jacket, sufficient pressure must be exerted on the grounds to press part of them through the thus widened aperture in the resilient end piece. By separating the coffee grounds from the rinse water, the device keeps the grounds out of the sewer system.
