Claims

[Scope of utility model registration request]

It is equipped with a cylinder having a hole in its head portion and a piston that reciprocates within the cylinder, the viscous material is introduced into the cylinder through the hole during the forward stroke of the piston, and the viscous material is introduced into the cylinder through the hole during the backward stroke of the piston. In an aseptic filling device for discharging a viscous material in a cylinder to the outside of the cylinder through the hole and reaching a filling nozzle, there is an annular space between the peripheral wall portion of the piston sandwiched between at least two seals and the inner peripheral surface of the cylinder. An aseptic filling device characterized in that the cylinder is provided with a sterile air injection pipe that opens toward the space.
