BACKGROUND OF THE INVENTION
The present invention is directed to methods and apparatus for dispensing liquids. More specifically, but without limitation thereto, the present invention is directed to dispensing cleaning products from a tamper proof container suitable for use in a jail, a correctional facility, a school, a public facility, or any other location where an apparatus for dispensing liquids may be subject to abuse and vandalism.
Liquid and soap dispensers have been used for many years. These dispensers are used in a number of applications, including: soap dispensers in restrooms, beverage dispensers, liquid dispensers at gas stations, etc. However, these devices are limited in their ability to prevent dispensing potentially dangerous and expensive liquids to unauthorized personnel.
SUMMARY OF THE INVENTION
In one embodiment, the present invention may be characterized as a tamper proof liquid dispenser that includes a cabinet enclosure having an open front for accessing interior components; a hinged faceplate covering the open front of the cabinet enclosure; a mixing unit fastened to an inside surface of the hinged faceplate for dispensing the selected liquid; a filling recess formed in the hinged faceplate for limiting a dimension of a container placed inside the filling recess; a filling nozzle coupled to the mixing unit for dispensing the selected liquid into the container placed inside the filling recess; a pushbutton coupled to the mixing unit through the hinged faceplate for causing the selected liquid to be dispensed through the filling nozzle; and a locking plate that may be detachably coupled to the hinged faceplate for restricting access to the pushbutton individually.
In another embodiment, the present invention may be characterized as a tamper proof liquid dispenser that is mounted on a wall to allow limited clearance for dispensing liquid into a container placed underneath, such as a mop bucket, while preventing filling of a larger container such as a garbage can.
In a further embodiment, the present invention may be characterized as a tamper proof liquid dispenser that includes a triple basin sink mounted underneath a tamper proof apparatus for dispensing a first liquid mixture, such as a soap mixture, into a first basin and a second liquid mixture, such as a sterilizer mixture, into a third basin of the triple basin sink.
