A press-out device for plastic substances comprises a cartridge (10) including a cylindrical container (11) in which a piston (35) can be displaced for pressing a substance, e.g. a sealing substance or adhesive substance, out of a discharge connector (14). The cartridge (10) is provided with an application nozzle (25) for use in extension of the discharge connector (14). The application nozzle (25) belongs to a reclosable closure assembly. The application nozzle (25) further comprises a hood (27) being movable relative to a nozzle body (26) and having a closure orifice. The closure orifice is followed by a discharge channel (51) delimited by straight side walls. The invention makes it possible to open the cartridge (10) without the need for a tool and to adjust and close the application nozzle (25) without the need for a tool.
