Abstract:
Disclosed is a two liquid type cartridge syringe having an improved exhaust structure, and more particularly, a two liquid type cartridge syringe having an improved exhaust structure, in which an exhaust structure for discharging air remaining in a cartridge to the outside is improved, in order to ensure that the air remaining in the cartridge is completely exhausted in the process of assembling a piston with the cartridge, thereby preventing the remaining air from suppressing forward movement of the piston inside the cartridge.

Claim (Index 1):
A two liquid type cartridge syringe comprising:\n a main body comprising a pair of cylinders, each formed in a tip end thereof with a discharge hole; and a piston configured to be introduced into a corresponding one of the cylinders so as to pressurize a filler stored in the cylinder and discharge the filler through the discharge hole, wherein the piston comprises a compressive rim portion and a sealing rim portion configured respectively so as to be brought into close contact with an inner wall of the cylinder and a connecting portion configured to interconnect the rim portions with a space therebetween, and the piston is configured so that the compressive rim portion, the connecting portion, and the sealing rim portion are sequentially introduced into the cylinder through an opened rear end of the cylinder, wherein at least one exhaust path is formed in the compressive rim portion and the connecting portion to discharge air remaining in the cylinder filled with the filler to an outer wall of the connecting portion, and wherein the piston sequentially performs an exhaust process of discharging the air remaining in the cylinder through the exhaust path while introducing the compressive rim portion into the cylinder and a sealing process of sealing a rear portion of the cylinder, from which the remaining air has been exhausted, via the sealing rim portion, so as to seal the cylinder in a state in which the air remaining in the cylinder has been discharged.
