The invention discloses a plunger-filter beverage-making machine with a lid which can be closed by a valve. The beverage-making machine has a vessel (2), a lid (3) and a filter piston (4) which can be vertically displaced in the vessel and has a piston rod (41). The lid (3) contains a pouring opening (37) which can be closed by means of an elongate lever (33) which extends transverse to the piston rod. To this end, the lever is mounted on the lid such that it can pivot about a horizontal axis. The lever has, in the region of its front end, a closure body (36) in order to close the pouring opening and, in the region of its rear end, an operating region (331) in order to pivot the lever by virtue of pressure exerted by a finger of a user.

The beverage-maker as claimed in claim 1, wherein the elongated lever is spring-loaded in the direction of its first position. 3. The beverage-maker as claimed in claim 2, having a compression spring which is disposed in a region of the lid, facing away from the spout, between the elongated lever and the top wall in order to subject the elongated lever to a spring force in the direction of its first position. 4. The beverage-maker as claimed in claim 3, wherein a cup-shaped depression, extending towards the vessel interior, is configured in the top wall, into which depression the compression spring extends. 5. A beverage-maker, comprising an upwardly open, substantially cylindrical vessel having a vessel bottom and a circumferential side wall;a filter piston vertically displaceable in the vessel, having a piston rod to whose upper end a grip element is attached, and to whose lower end a plunger-filter is attached, which plunger-filter is suitable for allowing the passage of liquid and, at the same time, for retaining solids; anda lid, which is passed through by the piston rod and has a top wall which at least partially covers the vessel in an upward direction and which, jointly with the vessel, delimits a vessel interior,wherein, on the lid or on the vessel, outside the vessel interior, a spout is configured, wherein the lid has a pouring opening, which is disposed between the piston rod and the spout in the top wall and which forms a connection between the vessel interior and the spout in order to pour liquid out of the vessel through the pouring opening by means of the spout, andwherein an elongated lever, extending transversely to the piston rod, is attached to the lid above the top wall pivotably about a horizontal axis, the elongated lever having a closure body in a region of its front end for closing the pouring opening, and the elongated lever having an actuating surface in a region of its rear end, facing away from the pouring opening, in order to pivot the elongated lever, by virtue of pressure exerted by a finger of a user, from a first position, in which the closure body closes the pouring opening, into a second position, in which the closure body frees the pouring opening,wherein the elongated lever has a through opening, through which the piston rod extends. 6. The beverage-maker as claimed in claim 1, wherein the lever has a bearing shaft extending transversely to the longitudinal direction of the elongated lever, or two coaxially arranged bearing journals extending transversely to the longitudinal direction of the elongated lever, wherein the lid has two mutually opposing, jaw-shaped bearing elements for the reception of the bearing shaft or bearing journals, and wherein the bearing shaft or bearing journals, in surmounting an elastic spring force, can be clicked into the bearing elements. 7. The beverage-maker as claimed in claim 1, wherein the closure body is made of a material which is softer than the material of the rest of the elongated lever. 8. The beverage-maker as claimed in claim 1, wherein the lid has a circumferential skirt, which extends vertically downward and extends into the vessel interior, and on whose outer side there is disposed a circumferential sealing element, which bears sealingly against the inner side of the side wall of the vessel. 9. The beverage-maker as claimed in claim 1, wherein the top wall of the lid is configured substantially flat, and in a region surrounding the pouring opening there is configured an upwardly protruding retaining web, which, starting from the spout, extends partially around the pouring opening in order to retain in the region of the pouring opening liquid running back from the spout. 10. The beverage-maker as claimed in claim 1, wherein the lid comprises a lid bottom part, which forms the top wall delimiting the vessel interior, and wherein the lid comprises a separately configured lid top part, which at least partially covers the lid bottom part and the elongated lever, and wherein on one of the lid parts, selected from lid bottom part and lid top part, there is configured a cylindrical guide sleeve for the piston rod, which is held in the other lid part such that the guide sleeve is secured against a lateral tilting motion. 11. The beverage-maker as claimed in claim 10, wherein the guide sleeve can be latched to the other lid part. 12.
