Pre-filled applicator device

A device for delivering a medicated product or the like to a bodily cavity is provided. The device includes a barrel member having a distal end. The barrel member is sized to contain the medicated product. The device includes a plunger sized to extend into the barrel member. A cap is adapted to move between a sealing position, in which the cap is positioned adjacent to the barrel member and seals the distal end of the barrel member, and a dispensing position, in which the cap is moved in a direction away from the barrel member. The cap includes at least one opening sized to allow the medicated product to flow through the cap when the cap is in the dispensing position. A retainer mechanism is provided for retaining the cap on the barrel when the cap is in the dispensing position.
