Claims
- 1. A tamper proof apparatus for dispensing a plurality of diluted liquids comprising:
a locked cabinet comprising:
a supply line coupled to a solvent supply; and a plurality of containers wherein each container holds a liquid chemical; and a supply line coupled to each container of said plurality of containers; and a mixing unit wherein said mixing unit is coupled to said solvent supply line and said container supply lines.
- 2. The apparatus of claim 1 further comprising at least one nozzle coupled to said mixing unit for dispensing a diluted liquid.
- 3. The apparatus of claim 2 wherein said at least one nozzle is protected by a shield.
- 4. The apparatus of claim 2 wherein said at least one nozzle is located in a filling recess.
- 5. The apparatus of claim 1 further comprising at least one pushbutton coupled to said mixing unit for causing said diluted liquid to be dispensed.
- 6. The apparatus of claim 5 wherein said at least one pushbutton is enclosed by a cylindrical wall to prevent tampering.
- 7. The apparatus of claim 5 further comprising a locking plate that may be securely fitted over said at least one pushbutton.
- 8. The apparatus of claim 1 further comprising at least one knob coupled to said mixing unit for causing said diluted liquid to be dispensed.
- 9. The apparatus of claim 8 further comprising a locking plate that may be securely fitted over said at least one knob.
- 10. The apparatus of claim 1 further comprising at least one lever coupled to said mixing unit for causing said diluted liquid to be dispensed.
- 11. The apparatus of claim 10 further comprising a locking plate that may be securely fitted over said at least one lever.
- 12. A method of dispensing a diluted liquid chemical comprising the steps of:
drawing a liquid solvent under pressure through a first supply line; and drawing a liquid chemical from a container through a second supply line; and mixing selected proportions of said liquid solvent and said liquid chemical; and dispensing said diluted liquid chemical through at least one nozzle; and securing said first supply line, said second supply line, and said container in a locked cabinet having a hinged faceplate.
- 13. The method of claim 12 wherein said method is actuated by pressing a pushbutton.
- 14. The method of claim 13 wherein said pushbutton is enclosed by a cylindrical wall to prevent tampering.
- 15. The method of claim 12 wherein said method is actuated by turning a knob.
- 16. The method of claim 12 wherein said method is actuated by pulling a lever.
- 17. The method of claim 12 wherein said diluted liquid is dispensed through at least one nozzle.
- 18. The method of claim 17 wherein said at least one nozzle is protected by a shield.
- 19. The method of claim 17 wherein said at least one nozzle is located in a filling recess.
