The top side of the dispenser has a valve disk (13) with an in particular round opening in which a valve body (1) provided with a valve stem (4) is secured. The valve stem (4) may be pressed against the force of a spring and co-operates with sealing elements to open the valve. The sealing elements have a sealing body with in particular plane or conical sealing surfaces that lie on plane or conical sealing surfaces of the valve body (1) in the closed position of the valve. The valve body (1) is a plastic composite body that consists of a hard inner part (2) and a soft outer part (3). The hard inner part (2) and the soft outer part (3) are intimately joined at their common contact surfaces into a non-detachable composite material by an injection moulding process.
