1. An applicator head for coupling to a reservoir for discharging liquid or paste-like medium from the reservoir, the applicator head comprising: a housing with a coupling device for coupling to the reservoir; an inlet opening facing the reservoir and an applicator opening for dispensing the medium into a surrounding atmosphere; a conveying device for conveying the medium from the inlet opening to the applicator opening; an actuating handle manually movable relative to the housing in order to actuate the conveying device; a one-piece seal and valve device including a ring seal region and a venting valve, the ring seal region being arranged on the applicator head in such a way that the ring seal region bears tightly against the reservoir once the reservoir has been coupled to the applicator head, the venting valve being formed by a curved surface of the one-piece seal and valve device, the curved surface having a slot-shaped aperture, wherein the slot-shaped aperture is closed by resilient deformation of the one-piece seal and valve device, and the slot-shaped aperture opens only with negative pressure on the side of the reservoir.
