Provided is a pneumatic dispenser cartridge (12) that is formed by fitting a plunger (10) into a cylinder (18). The plunger (10) has a main body part (80) and has a seal part (104) that, when the plunger (10) has been fitted into the cylinder (18), is formed between an outer circumferential surface (82) of the plunger (10) and an inner circumferential surface (84) of the cylinder (18). When the plunger (10) has been fitted into the cylinder (18), a substantial radial clearance exists between the inner circumferential surface (84) and the entire circumference of the outer circumferential surface (82), and as a result, a cylindrical clearance (106) that is continuous in both the axial direction and the circumferential direction is formed between the outer circumferential surface (82) and the inner circumferential surface (84). When a filling chamber (72) is filled from the outside with a viscous material, the clearance (106) is partially filled with the viscous material, and, as a result, the seal part (104) is formed. |
