  • Patent number: 7320418
    Abstract: Controlled sanitizing by dispensing a germicide, such as a disinfectant, antibacterial solution or cleansing agent at intervals. A system can include a housing sized to seat an aerosol can and a control circuit that operates to momentarily open a valve on the aerosol can through action of a gear system upon an aerosol delivery tube. A sensor responds to displacement of the delivery tube to deliver state signals to the control circuit. The control circuit prevents action of the gear system in the event that the state signals fail at least one prescribed condition. A method registers at least the displacement of the delivery tube via the sensor and prevents subsequent displacements and hence subsequent sanitizing in the event that the sensor has not registered at least the displacement of the delivery tube. The method ensures that a suitable aerosol can has been properly loaded in the dispenser.
