ABSTRACT:
A discharge apparatus provided as a single spray has in the interior of the discharge connection as an evaporation barrier for the medium a rotary closure, which can be opened and closed by a mutual rotation of the casing and the head or the body and the medium reservoir. For this purpose a shaft part in the form of a filler is formed from two longitudinally, interconnected bar parts, which rotatably engage in one another and form closure parts of the closure located within a cover sleeve. This allows very long storage times of the filled discharge apparatus.
