ABSTRACT:
Valve syringes of the invention include a barrel, a plunger and an applicator valve. The applicator valve, which controls the flow of the fluid material contained within the barrel, can rotate at the end of the barrel between an open position and a closed position. In the open position, slots in the applicator valve align with holes in the barrel and allow the fluid material to flow therethrough. In the closed position, a contact surface seals the holes in the barrel closed to prevent the flow of the fluid material therethrough. The applicator valve includes an applicator tip that is either integrally connected to or detachably connected with the applicator valve. The valve syringe also includes means for releasably securing the applicator valve in the closed position to prevent undesired leaking and evaporation during periods of nonuse.
