Dilution dispensing system with product lock-out

摘要

An apparatus and method for dispensing a dilute liquid concentrate with a diluent to form a dilute use solution for dispensing into a bottle. The dispensing apparatus includes an aspirator 60 and a controller 50. The controller 50 includes an activation switch that is operable by being depressed in a first direction. A slide actuator 80 is mounted relative to the controller for movement in a second direction. The dispensing apparatus also includes a lock-out member (300, figure 8) to prevent the inadvertent use of an incorrect bottle while dispensing the use solution by means of cooperating shaped parts on the bottle 41' and the dispenser (100, figure 5).
