ABSTRACT:
A water vending machine is provided of the type having a water purification system for producing a supply of relatively purified water for dispensing into a customer-supplied container such as a water bottle. The vending machine includes an open dispense chamber for receiving and supporting the water bottle beneath a dispense nozzle through which water is delivered in response to coin-initiated operation of a machine control panel. A trap door normally conceals and thereby prevents unauthorized access to the dispense nozzle, wherein the trap door is retracted upon operation of the control panel to expose the dispense nozzle and permit water dispensing to the bottle. In addition, the vending machine includes an improved door lock assembly including a square-shaped and rotatable main lock cartridge seated in a locked condition within a matingly shaped lock case, wherein this door lock assembly provides improved security locking of a machine access door.
