ABSTRACT:
A pre-fill vaginal applicator comprising a tubular barrel having an open end and a dispensing end provided with at least one dispensing opening formed therein. A selectively removable closure, such as a snap cap or threaded cap, closes the dispensing end of the barrel. A resilient piston is selectively slidably positioned in the barrel and has an outer surface which is in sealing contact with the inner surface of the barrel to define a medication reservoir between the piston and dispensing end of the barrel. An elongated plunger is adapted to be inserted into the open end of the barrel so that the inner end thereof may be detachably connected to the piston. After the plunger has been connected to the piston, inward movement of the plunger causes the piston to force medication from the medication reservoir outwardly through the dispensing opening. Outward movement of the plunger with respect to the piston causes the plunger to disconnect from the piston.
