A pressurized applicator and concentrate carriage system provides a concentrate container support having a spout guide and lock structure which permits a pump dispenser unit to operate when a spout is over a central opening and disenables pump dispenser unit operation when the spout is swung away from the main opening. The concentrate container support has several methods of installation and includes an opening with a specialized groove to provide non-vertical slip stabilization to the concentrate container. A collar adapter carries a circumferentially outwardly projecting land for interfitting with the specialized groove.
