The present invention relates to a dispensing adaptor for one-component polyurethane foam. The dispensing adaptor is coupled to a valve stem of a polyurethane-foam pressurised container. The dispensing adapter comprises: a tubular main adaptor body which is coupled to the valve stem and leads the polyurethane foam outside the pressurised container; a stem coupling part formed on one end of the main adaptor body and communicably coupled to the valve stem; a discharging tube part extending from the other end of the main adaptor body; a fixed lever part extending integrally from the outer wall surface of the main adaptor body; and an extended lever part which extends curvedly from the fixed lever part in the length direction of the pressurised container, and which causes the valve stem to open by tilting relative to the axial direction. Therefore, the present invention can be operated while holding the pressurised container and the extended lever part in one hand, by means of the fixed lever part extending integrally from the outer wall surface of the main adaptor body to the side relative to the axis of the pressurised container, and the extended lever part which extends curvedly from the fixed lever and curved in the length direction of the pressurised container, and hence the invention provides work efficiency and safety, and makes it possible to recycle a disposable dispensing adaptor by temporarily closing an end part of the dispelling tube when idle. |
