摘要：
A dispensing device includes an actuating device that actuates first and second containers, respectively, and a sensor for detecting an environmental condition. In a first period the actuating device is inactive, in a second period the actuating device actuates the first container at a first frequency, and in a third period the actuating device actuates the second container at a second frequency. If the sensor has detected the environmental condition, the actuating device actuates the first and/or second containers, respectively, during a fourth period at a third frequency.
