Patent ID: 7442179

Claim:
A pre-fill vaginal applicator, comprising: a tubular barrel having a dispensing end provided with at least one opening formed therein and an open end; said barrel having an inner surface; a selectively removable closure closing said dispensing end of said barrel; a resilient piston having first and second ends, selectively slidably positioned in said barrel; said piston having an outer surface which is in sealing contact with said inner surface of said barrel to define a medication reservoir between said first end of said piston and said dispensing end of said barrel; said second end of said piston having an opening extending thereinto which terminates between said first and second ends of said piston; an elongated plunger having first and second ends adapted to be inserted into said open end of said barrel whereby said first end thereof may be inserted into said opening in said second end of said piston to detachably connect said plunger to said piston; said piston, prior to insertion into said barrel, having a larger outside diameter than the inside diameter of said barrel whereby said piston is in a compressed state against said inner surface of said barrel when said piston is inserted into said barrel; said plunger, when connected to said piston and being moved towards said dispensing end of said barrel, causing said resilient piston to longitudinally stretch to permit said piston to slide towards said dispensing end thereby forcing medication in said medication reservoir to be ejected from said opening in said dispensing end of said barrel; said first end of said plunger being detachably connected to said piston whereby movement of said plunger away from said piston will cause said first end of said plunger to disconnect from said piston so that said piston remains in said barrel thereby ensuring that the applicator may not be reused.
