Abstract
Permanently or detachably mounted on a container (,) is a dosing and metering device that contains a pressure bellows (,), through which a valve-plate holder (,) passes. The valve-plate holder (,) essentially has the shape of a hollow cylinder and exhibits gaps or lateral openings (,), to enable communicating contact between pressure bellows (,) and container (,). The valve-plate holder (,) is arranged in a transition zone between pressure bellows (,) and container (,), in a fixed position relative to the container or container neck. The valve plate (,) attached to the end of the valve-plate holder (,) forms a valve seat (,) together with the constriction (,) between pressure bellows (,) and the metering chamber (,) that follows it. Axial pressure upon the metering chamber (,) allows the metering chamber to be entirely or partly filled or drained back into the container, as desired, in which case the contents of the metering chamber can be poured out when the cap is removed.
