Abstract
This structure includes a resilient collar having a central boss with an opening which receives the discharge apparatus, such as a pump or valve. The collar fits over the flange of the container and has an outward protrusion in the form of fingers. A sleeve is sized to slide down over the side of the collar where it surrounds the flange and cams inwardly the protrusion to hold the collar on the container. The improvement relates to a re-entrant portion at the upper end of the sleeve which extends downward in an inner tube terminating at its lower end in a short inward annular flange which grips the sides of a central boss on the collar to keep the sleeve from being vertically displaced.
