Abstract (en)
The cartridge, to be filled with a paste material, has a cylindrical body (1) and a two-part piston with air relief. The piston section (2) which is tightly against the inner wall of the cartridge has an air escape channel (5), and the piston head section (3) against the paste material filling (6) has a convex curvature with air vent opening(s) which can be closed, to allow air to pass through into the escape when the cartridge is being filled until it is full, when the paste covers the outlet opening(s).
