Abstract
The present invention can be characterized as a tamper proof apparatus for dispensing liquid or cleaning product for use in a environment where abuse or vandalism may occur and a method of operating the apparatus. The apparatus includes a first chamber, a second chamber coupled to the first chamber, a first lockable door recessed within one of the first chamber and the second chamber such that a first hinge pin is not removable, a mixing unit within the first chamber. An output hose in one of the first chamber and the second chamber is coupled to the mixing unit and to a feed-through such that the output hose is not exposed outside the chambers. A faceplate with an indentation within the first chamber prevents filling large containers with liquid while also preventing damage to the mixing unit.
