A dispenser includes a housing that holds first and second refill units, each including a product container and a valve assembly that receives prod-uct from the product container. An actuator mechanism associates with the first re-fill unit and is actuated to force air into the associated valve assembly and dispense product from the valve assembly until such time as the product container associat-ed with that valve assembly is empty. When empty, a float valve of the valve as-sembly prevents the actuation of the actuator mechanism and forces the actuator mechanism to associate with the second refill unit. While so associated, the first re-fill unit can be replaced, thus, helping to ensure that the dispenser does not run out of product. |
