ABSTRACT:
An improved dispensing syringe for a fluid glue, which comprises a syringe stem, a syringe seat, a syringe cap, a guide sleeve and a sealing pad; the syringe seat has a conic cylindrical opening at one end, and a contact surface and a guide hole on the other end thereof; one end of the syringe stem has a bevel opening, being mounted in the center of the conic cylinder opening while the other end thereof is a flat opening, being set out of the syringe seat. There is a given length between the flat opening and the syringe seat. The syringe stem and the syringe seat are connected together by glue. The dispensing syringe is mounted to the conic cylinder on the container with a stinging through method so as to draw the glue to flow out. The inside of the syringe cap is mounted with a guide sleeve and sealing pad; the syringe cap is used for closing the syringe stem after dispensing the glue each time; the guide sleeve is used for guiding the front end of the syringe stem to move in the center of the sealing pad, i.e., to have the flat opening isolated from the atmosphere by means of a blind hole in the sealing pad so as to prevent the cyanoacrylate from contact the atmosphere. The glue in the container can be used again upon the syringe cap being removed. In case of the sealing pad being out of order or missing, a polymerizing curved surface in the front end of the syringe stem will cause the glue to be polymerized as a sealing of the container.
