Abstract
A discharge apparatus for flowable media, comprising: a basic body, at least partly receiving a pump unit; the pump unit having a pump chamber connectable to a discharge opening via a discharge channel; a pump cylinder and a pump piston bounding the pump chamber; the pump cylinder forming a medium reservoir; the pump piston being displaceably guided in the pump cylinder for discharging all the medium contained in the medium reservoir by a single pump stroke in a pump stroke direction; and, at least one breakable material bridge between the pump unit and the basic body which can be destroyed by an actuating force exerted in the pump stroke direction, whereby the medium is discharged from the apparatus with a predetermined discharging pressure by a predetermined actuating force level and the apparatus is provided with a destroyable tamper-evident closure.
