摘要: A cartridge-type dispenser has a cartridge main body with a filling space, an extrusion nozzle on the front, and a piston slidably disposed in the filling space. The piston extrudes contents of the filling space from the extrusion nozzle by applying a push-in force. The piston includes a trunk portion having an outer circumferential wall running along an inner wall of the main body with a gap therebetween, a front wall on one end of the trunk portion directly contacting the contents of the filling space, and a rear wall on the other end whereon a rod of a push-in tool applies the push-in force on the piston. On the outer circumferential wall of the trunk portion, protrusions are provided, which contact the inner circumferential wall of the main body. The points of contact form sliding parts of the piston but do not seal the main body interior.
