ABSTRACT:
This invention discloses a syringe closure used with a nozzle and flexible bag in which fluid is initially flowed. This closure apparatus includes a retainer ring of generally tubular and tapered construction. This retainer ring has an outwardly disposed groove formed at its lower and smaller diameter end in which a bead end of the flexible bag is mounted. An outer safety ring also of generally tubular configuration is mounted on this retainer ring and insures retention of the bead end of the bag in the groove. A nozzle retainer member having an inner aperture in which the nozzle is removably mounted has an outwardly generally circular projecting lip sized and adapted to snap in and seat in an inwardly disposed recess formed in the retainer ring. Where and when the nozzle retainer member is displaced from the arcuate retaining recess in the retainer ring the secured flexible bag may be manipulated to pass through the large aperture in the retainer ring and into an inside out condition whereat the inside surface of the bag may be washed and/or dried and then again manipulated through said large aperture to again be arrayed in the conventional position whereby it may be filled with fluid and the nozzle retainer member again mounted in the arcuate recess in the retainer ring.
