ABSTRACT:
A metering stopper for the neck of a bottle is described, with which a liquid medium is delivered in metered quantities. A tubular metering housing encloses a metering chamber which is provided with an outlet bore, the wall of which metering chamber has recesses for the admission of liquid into the inside of the metering chamber and in which a float is inserted which slides in sealing manner along the inner wall of the metering chamber. The float, the specific weight of which is in each case greater than the specific weight of the liquid to be delivered, has a cone, the tapered tip of which interacts with a valve seat in the outlet bore of the metering chamer. When the bottle is tilted, liquid enters through the recesses in the wall of the metering chamber and, as soon as the metering space of the latter is filled with liquid, the float, when the liquid is flowing out through the outlet bore, moves downwards towards this outlet, and the cone closes the valve seat as soon as the metered liquid quantity has flowed out. By varying the displacement of the float in the metering chamber, the liquid quantity to be delivered can be selected as desired.
