    摘要: A dripless syringe for dispensing a material such as glue, caulking, cement, foods, cosmetics, paint, oil, pharmaceuticals; etc., and any other materials suitable for dispensing thereby. The syringe plunger includes a generally hemispherically-shaped piston portion for pushing the material out of the syringe. Except for the piston portion, the plunger slides easily within a barrel of the syringe. In operation, the hemispherical piston portion is deformed during dispensing, but returns to its original shape after dispensing is finished. Upon returning to its original shape, the piston portion stops further dispensing of the material from the syringe.
