Реферат: 1. A method for supplying the reservoir (7) of a soap solution metering device with an extraction device (16, 17, 17') disposed downstream, characterized in that the reservoir (7) is supplied with the soap solution from at least two outlet openings (6, 6') which are arranged stepped behind one another at different levels by operating the extraction device (16, 17,17'), each outlet opening (6, 6') is supplied with soap via a separate container (3, 3'), that at each respective higher level of the soap solution at least one outlet opening (6') disposed lower down is kept closet until the level of the soap solution reaches the next lowest outlet opening (6') and due to the level of the soap solution dropping further permits the entry of outside air into the next lowest outlet opening (6') thus causing an outflow, these steps being repeated until the level of soap solution is reduced below the lowest outlet opening (6') by operating the extraction device (16, 17, 17').
