PURPOSE: To provide a cartridge for an emission device capable of applying proper coating to a surface to be caulked different in width by the same discharging orifice and to obtain a smooth caulking surface without any trouble some work using the cartridge.

CONSTITUTION: This cartridge for a discharging device equipped with an almost conical nozzle 3 directing a filler in one direction and being oval in its cross-sectional shape vertical to the axial line of the hollow part in the vicinity of at least the apex of the nozzle 3 is obtained. The nozzle 3 of the cartridge 1 is obliquely cut with respect to the axial line of the hollow part to form an almost planar cut surface and the cut surface is used in opposed relation to the surface to be caulked.
