Abstract

Valve syringes of the invention include a syringe barrel (12) and an applicator valve (30) adapted to rotate relative to the barrel (12) between closed and open positions. In the open position, one or more slots in the applicator valve (30) align with one or more holes (34) in a discharge end of the syringe barrel (12) in order to allow fluid material to flow therethrough. In a closed position, the contact surface of the applicator valve (30) occludes the holes (34) in the barrel in order to seal them and prevent flow of fluid material therethrough. The valve syringe may include structure that increases the sealing engagement between the syringe barrel (12) and applicator valve (30) when rotated toward at least one of the open or closed positions. The applicator valve (30) may include an applicator tip that is either integrally or detachably connected to the applicator valve (30). The valve syringe may also include a plunger (20) adapted to expel fluid material contained in the syringe barrel (20) through the discharge end and into the applicator valve (30).
