Abstract

A dispenser includes a housing that holds first and second refill units, each including a product container and a valve assembly that receives product from the product container. An actuator mechanism associates with the first refill 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 associated with that valve assembly is empty. When empty, a float valve of the valve assembly prevents the actuation of the actuator mechanism and forces the actuator mechanism to associate with the second refill unit. While so associated, the first refill unit can be replaced, thus, helping to ensure that the dispenser does not run out of product.
