US Patent 7694873 Installation of germicidal lights in vending machines

A vending machine for dispensing products includes a germicidal light for disinfecting a product dispensed by the vending machine. The germicidal light is positioned adjacent an exit chute of the vending machine such that it exposes the product to a sterilizing frequency of light when the product is dispensed. Alternatively, the products may be intermittently exposed to the sterilizing light while the products are on display in accordance with a predetermined exposure schedule. The invention is particularly effective when it is used in connection with a canned drink machine.
