Syringe closure assembly with attachable nozzle

Claim 1

A syringe closure assembly with retaining means for an attachable nozzle, the nozzle having sufficient resiliency for comfort by the user and having a fluid passageway therein and compatible attaching means to the closure assembly, said closure assembly including: (a) a retainer ring of a generally tubular configuration and having an aperture therethrough and a lower end of said ring having an outwardly directed annular groove portion formed thereon and at the other end of said retainer ring there is formed an inwardly disposed annular arcuate retaining recess; (b) a nozzle retainer member having an inner aperture formed to provide detachable mounting and retaining means for a syringe nozzle, said nozzle retainer having an outwardly generally circular and planar projecting lip sized and adapted to snap into and thereby seat in a fluid tight manner with the inwardly disposed arcuate retaining recess in the retainer ring; (c) a hinge connection having one end attached to an edge portion of the retainer ring and the other end attached to an outer extreme portion of the nozzle retainer, said hinge being of molding material that is slightly resilient and being integral with the retainer ring and nozzle retainer member so that substantially simultaneous molding may be performed, said hinge canted upwardly so as to avoid obstruction to inserting and seating the projecting lip of the nozzle retainer in the inwardly disposed arcuate retaining recess in the retainer ring when said projecting lip and said retaining recess are attachably mounted; (d) a flexible bag of material generally impervious to fluid contained therein and having a resilient neck portion which includes a bead or band which is mountable in the outwardly directed annular groove portion of the retainer ring; and (e) an outer safety retainer ring of a generally tubular configuration and having at least one retaining means formed thereon and disposed to engage and to be secured onto the retainer ring by engagement with the outer surface of said retainer ring thereby to retain the mounted bead or band of said flexible bag in said groove of the retainer ring, whereby when the nozzle retainer member is displaced from the arcuate retaining recess in the retainer ring, the secured flexible bag may be manipulated pass through the aperture in the retainer ring and into an inside-out condition whereby the inside surfaces of the bag may be washed and/or dried and then again manipulated through said aperture to be arrayed in a conventional position whereby it may be filled with fluid and the nozzle retainer membe snapped into place to provide mounted retention in the arcuate recess in the retainer ring.
