A lock-out mechanism for use with a dispenser having a back plate and a cover hingedly attached thereto for receipt of a refill container with an attached pump. The cover carries a pressure member in the form of a push bar having a pump activating projection which normally activates the pump by engaging a collapsible portion thereof when the push bar is activated and the refill cartridge and pump are properly seated within the dispenser. The push bar also carries an interference rib on the push bar which projects therefrom and engages a non collapsible portion of the pump and prevents the pump activating projection from engaging the collapsible portion of the pump when the pump is misseated in the dispenser.
