Abstract:
A beverage maker including a cylindrical chamber having a closed end, a pouring spout and a separator piston disc which is slidable within the cylindrical chamber, the separator piston disc being permeable to water and the beverage whilst being impenetrable to solid raw material from which the beverage is made, the arrangement being such that the solid raw material is placed in the cylindrical chamber and the cylindrical chamber is filled with hot water which interacts with raw material to form the beverage, there being a screw which is coupled with the separator piston disc and which is supported substantially coaxially within the cylindrical chamber for rotation about its axis relative to the cylindrical chamber so that the separator piston disc moves within the cylindrical chamber with rotation of the screw and means operable to turn the screw whereby the separator piston disc is driven within the cylindrical chamber to separate the residue of the raw material from the resultant beverage, wherein the pouring spout is spaced from the closed end, the separator piston disc is slidable within the cylindrical chamber between the pouring spout and the closed end and is adapted to be driven towards the closed end, the solid raw material being placed in the cylindrical chamber between the closed end and the separator piston disc, and the screw has a multistart thread.
