A one-way valve positioned between the nozzle and container of a disposable douche, which is opened and closed by axial movement of the nozzle relative to the container, permitting discharge of the douche contents without permitting backflow. The neck of the container opening having an intermediate cap with axial discharge holes and a flexible valve disk overlying such holes all within the bore of the base of the nozzle. In the closed position, the inner shoulder of the nozzle base seat against the flexible valve disk presenting discharge of the contents through the discharge opening of the intermediate cap. With the axial displacement of the nozzle away from the main body of the container, the valve disk, freed of the internal restraining shoulders of the nozzle base, can flex to permit flow of the contents of the container into the nozzle. The nozzle base's bore and the intermediate container cap have slidable inner-fitting surfaces to prevent fluid discharge therebetween, such that all fluid is discharged out of appropriate nozzle openings in the free end of the nozzle.
