Abstract: A dispenser for liquid, gel, granular or powdered media, comprising an outer container of rigid material in which a suction pump is operated by a trigger mechanism. A pump outlet is connected via a flexible tube to a spray nozzle, and via a suction tube to a connector tube. A refill packing is provided within the outer container and includes an integrally manufactured connector that can be pressed onto the connector tube. The connector tube opens the connector upon insertion thereinto. A special plug, including guide arms, ensures that the connector opens upon insertion of the connector tube, and closes again upon withdrawal of the connector tube from the connector. The connector/connector tube assembly provides leak-free connection of the refill packing within the outer container.
