Abstract

There is illustrated in the drawings a discharge tube mounting a nozzle which is releasably closed at its outer, terminal end by a plug. A spaced distance above the base of the nozzle there is mounted a flange ring arranged to extend around the nozzle circumference, the flange ring being cut at one point. A rotatable and removable closing cap is fitted over the nozzle and includes at its lower rim an inwardly projecting nib configured to be captured between the flange ring and the upper rim of the tube to secure the cap to the tube, and to pass through the cut portion of the flange ring when aligned with it, to allow removal of the cap. The lower rim of the closing cap or the upper rim of the discharge tube mounts a separate background ring, preferably of a different color than the closing cap and discharge tube, and the ring is disposed behind a downwardly extending arrow-shaped indicator on the cap and behind an upwardly extending arrow-shaped indicator on the upper rim of the discharge tube. When the cap is rotated to align the opposing indicators, the nib is positioned in alignment with the cut portion of the flange and the cap may then be pulled upwardly and removed, thereby exposing the nozzle for use.
