A dispensing spout and cap assembly (1) having a dispensing spout, which is mountable on a container for a liquid product or is integral with the container. The spout (2) has a dispensing channel (4) with an inlet opening (5) and a dispensing opening (6) for the product to be dispensed from the container. In the dispensing channel a self-closing valve (10) is arranged for closing the dispensing channel. The self-closing valve and the dispensing spout are manufactured by co-injection of a first thermoplastic material for the valve and a second thermoplastic material for the spout, wherein the second material is more rigid than the first material. The assembly further comprises a movable cap (15) for closing the dispensing channel near the dispensing opening, which cap has an annular sealing surface (20) that co-operates with an associated annular sealing surface (13) of the spout. The spout is provided with an annular sealing element made from the first thermoplastic material and formed during the co-injection, which sealing element forms the sealing surface of the spout co-operating with the cap.
