An applicator head for discharging a pasty medium from a container, including a metering chamber, a first housing part bounding the metering chamber in sections, with an actuating element, and a second housing part. The first housing part and the second housing part form a constructional unit connectable to a container storing the medium and closing the container. By actuating the actuating element, the medium is conveyed out of the container into the metering chamber and/or is discharged from the metering chamber. A sealing element of a plastically or elastically deformable plastic is provided, and is arranged such that the container is closable in a sealing manner by the constructional unit. The sealing element is manufactured as a common component with at least one further element of the applicator head.
