The interior wall of the cap contains a dispensing notch which is aligned straight across with a dispensing opening through the exterior wall. With rotation, the cap raises and lowers on threads relative to the container. When the cap is lowered, the container neck blocks the dispensing canal between the notch in the interior wall and the dispensing opening in the exterior wall of the cap. The top rim of the container neck abuts the interior cap ceiling between the two walls to form a seal. When the cap is raised, the container neck is in part below the notch in the interior wall and the dispensing opening, and thus the dispensing canal is open.

Abstract: A device is used for spraying and atomizing a liquid which is held in a container which can be emptied by air pressure. If in a device of this kind a liquid nozzle projects into a mixture nozzle disposed coaxially in front of it, so that an annular space provided for air around the liquid nozzle is open at the front towards the mixture nozzle, the feed paths for liquid and for air must not be transposed. Such transposition occurs if the container is held upside-down during spraying. In order to avoid this disadvantage two annular spaces are provided, from which passages lead to a mixture nozzle. The two annular spaces communicate with one another via throttle slots. Because of the two annular spaces the liquid can also be sprayed when the container is upsidedown.

Abstract: The dispensing device serves for discharging a free-flowing medium from a container. An insert arranged in the container neck and filling the clear cross-section of the latter has a design suitable for discharging the free-flowing medium. The insert resting on the container neck is held firm by a catch having a bead on the container neck and a groove on the insert. In the case of a container intended for refilling, this catch can be overcome and the insert can be pulled out from the container neck by a cam projecting radially on the inside of the screw cap and engaging behind the end flange. If reuse of the container is to be ruled out, the cam on the cap is absent. In the case of a modified embodiment, the bead extending into the groove and the groove itself are dimensioned to be of different sizes in the radial direction. If the bead is dimensioned to be larger, the catch cannot be overcome.
