Abstract

Methods, apparatuses, and systems for dispensing an off-gassing liquid product mixed with a diluting product are provided. A liquid product or product solution is moved through an unprimed product line and towards a dispenser. The liquid product is combined with the diluting product to create a solution. The solution is dispensed. The product line is cleared of unused liquid product to unprime the product line after the dispensement of the solution. The unused product may be directed back into a product container from which it was held.

First claim

What is claimed is:

1. A method of dispensing an off-gassing liquid product from a product container, comprising:
moving the liquid product through a product line and towards a dispenser, said product line extending from the product container to the dispenser;
combining the liquid product with a diluting liquid product to create a solution;
dispensing the solution; and
clearing substantially all of the product line of unused liquid product to unprime the product line after each dispensement by draining the unused liquid product by gravity;
said clearing the product line of unused liquid product comprises at least some of the unused liquid product being drained into the product container via the same product line but in an opposite direct than when the liquid product is moved towards the dispenser.

2. The method of claim 1 wherein the liquid product and diluting product are combined to create a solution having a desired concentration.

3. The method of claim 2 further comprising dispensing the solution for a predetermined amount of time such that the solution comprises a desired concentration.

4. The method of claim 2 further comprising dispensing the solution to a predetermined volume to create a desired concentration.

5. The method of claim 1 further comprising draining the unused liquid product from the product line after each dispensement.

6. The method of claim 5 wherein the unused liquid product is drained into both the product container and a secondary container.

7. The method of claim 1 further comprising venting the product container to reduce displacement of the product.

8. The method of claim 1 further comprising coloring the liquid product prior to moving the product to ensure that the product is being moved.

9. The method of claim 1 wherein the step of moving the liquid product comprises aspirating the product.

10. The method of claim 1 wherein the step of moving the liquid product comprises pumping the product.

11. A dispensing system for dispensing an off-gassing liquid product mixed with a diluting, product, comprising:
a dispenser including a dispenser outlet;
a product container containing the liquid product;
an unprimed product line extending from the product container to the dispenser; and
a diluter line operatively connected to the product line to combine the liquid product and the diluting product proximate the dispenser outlet;
said unprimed product line configured to allow substantially all of an unused amount of the liquid product to drain, via gravity, from the dispenser and into the product container after use of the dispenser to prevent expansion of the product caused by the product chemistry;
said unprimed product line being the passage for removal and return of the liquid product.

12. The dispensing system of claim 11 wherein the unprimed product line having no valves within the line.

13. The dispensing system of claim 11 further comprising a venting fitment operatively connected to the product container to vent gas and/or pressure produced by the liquid product.

14. The dispensing system of claim 11 further comprising a mixing chamber attached to the dispenser outlet.

15. The dispensing system of claim 14 wherein the product line and diluter line are attached to the mixing chamber.

16. The dispensing system of claim 15 further comprising a bottle coupler positioned between the product container and the product line.

17. The dispensing system of claim 16 wherein the bottle coupler and product container include a valve for sealing each when not connected to one another.

18. The dispensing system of claim 16 further comprising a product enclosure at least partially surrounding the product container, the bottle coupler, and at least a portion of the product line.

19. The dispensing system of claim 18 further comprising a dispenser enclosure at least partially surrounding the dispenser, mixing chamber, and at least a portion of the product line and diluter line.

20. The dispensing system of claim 11 further comprising a pump operatively connected to the product line and configured to draw the liquid product from the product container and towards the dispenser outlet.

21. The dispensing system of claim 20 wherein the pump is also configured to move any unused liquid product towards the product container.

22. The dispensing system of claim 11 wherein the unprimed product line allows fluid flow in either direction for the entire length of the line.

23. The dispensing system of claim 11 wherein the unprimed product line comprises polyvinylidene difluoride (PVDF).
