Abstract

A formulation delivery system for use with an outdoor cleaning device is provided. The formulation delivery system has a composition containing chlorine, wherein the composition is in a form of a solid chemistry and the outdoor cleaning device is a spray wand containing the composition. The chlorine is selected from the group consisting of calcium hypochlorite; 1,3,5-Triazine-2,4,6(1H,3H,5H)-trione, 1,3-dichloro-, sodium salt, dihydrate (dichlor); 1,3,5-Trichloro-1,3,5-triazinane-2,4,6-trione (trichlor), chloramine-T hydrate, and a combination thereof. A spray wand having a refill cartridge for containing the composition in solid form is also provided.

First claim

What is claimed is:

1. A formulation delivery system for use with an outdoor cleaning device, the formulation delivery system comprising:
a cleaning composition comprising chlorine, wherein the composition is in a form of a solid chemistry, and
the outdoor cleaning device is a spray wand having the cleaning composition positioned within a dispensing cartridge housed within the outdoor cleaning device, wherein:
the dispensing cartridge is axially aligned with a longitudinal axis of the outdoor cleaning device, and
the dispensing cartridge comprises a swirl chamber positioned therein that converts a single liquid stream flowing along the longitudinal axis of the outdoor cleaning device into a plurality of cyclonic liquid streams flowing along the longitudinal axis of the outdoor cleaning device that flow over and dilute the cleaning composition therein.

2. The formulation delivery system according to claim 1 , wherein chlorine is selected from the group consisting of calcium hypochlorite; 1,3,5-Triazine-2,4,6(1H,3H,5H)-trione, 1,3-dichloro-, sodium salt, dihydrate (dichlor); 1,3,5-Trichloro-1,3,5-triazinane-2,4,6-trione (trichlor), chloramine-T hydrate, and a combination thereof.

3. The formulation delivery system according to claim 2 , wherein the composition further comprises an ingredient selected from the group consisting of sodium sulfate, magnesium stearate, sodium metasilicate, sodium silicate, magnesium silicate, calcium chloride, calcium hydroxide, calcium carbonate, sodium chloride, water, and a combination thereof.

4. The formulation delivery system according to claim 1 , wherein the solid chemistry is in a shape of a tablet, bead, cylinder, circle with ridge, pellet, and a combination thereof.

5. The formulation delivery system according to claim 1 , wherein the chlorine-containing composition comprises calcium hypochlorite in a range of 40 weight % active to 75 weight % active, and an inert or other ingredient in a range of 25 weight % to 60 weight % based on the weight of the chlorine-containing composition.

6. The formulation delivery system according to claim 1 , wherein the chlorine-containing composition comprises dichlor mixed with sodium sulfate and magnesium stearate in an amount of 35% to 100% dichlor by weight.

7. The formulation delivery system according to claim 1 , wherein the chlorine-containing composition comprises dichlor in combination with a component selected from the group consisting of sodium sulfate, magnesium stearate, sodium chloride, calcium chloride, calcium carbonate, sodium silicate, magnesium silicate, sodium metasilicate, and a combinations thereof.

8. A spray wand comprising:
a spray wand body having a hollow tube with an adjustable wand spray end that varies dispensing flow patterns from the spray wand,
a refill cartridge having a swirl chamber configured to be housed within the spray wand body in which the refill cartridge is axially aligned with a longitudinal axis of the spray wand when the spray wand is fully assembled and the swirl chamber is spaced apart from the adjustable wand spray end when the spray wand is fully assembled,
a wand hose end having a handle connected to the spray wand body having the cartridge; and
a cleaning composition comprising chlorine in the refill cartridge assembly, wherein
the composition is in a form of a solid chemistry, and
the swirl chamber is configured to convert a single liquid stream flowing along the longitudinal axis of the spray wand into a plurality of cyclonic liquid streams flowing along the longitudinal axis of the spray wand that flows over and dilute the cleaning composition therein.

9. The spray wand according to claim 8 , wherein chlorine is selected from the group consisting of calcium hypochlorite; 1,3,5-Triazine-2,4,6(1H,3H,5H)-trione, 1,3-dichloro-, sodium salt, dihydrate (dichlor); 1,3,5-Trichloro-1,3,5-triazinane-2,4,6-trione (trichlor), chloramine-T hydrate, and a combination thereof.

10. The spray wand according to claim 9 , wherein the composition further comprises an ingredient selected from the group consisting of sodium sulfate, magnesium stearate, sodium metasilicate, sodium silicate, magnesium silicate, calcium chloride, calcium hydroxide, calcium carbonate, sodium chloride, water, and a combination thereof.

11. The spray wand according to claim 8 , wherein the chlorine-containing composition comprises calcium hypochlorite in a range of 40 weight % active to 75 weight % active, and an inert or other ingredient in a range of 25 weight % to 60 weight % based on the weight of the chlorine-containing composition.

12. The spray wand according to claim 8 , wherein the chlorine-containing composition comprises dichlor mixed with sodium sulfate and magnesium stearate in an amount of 35% to 100% dichlor by weight.

13. The spray wand according to claim 8 , wherein the chlorine-containing composition comprises dichlor in combination with a component selected from the group consisting of sodium sulfate, magnesium stearate, sodium chloride, calcium chloride, calcium carbonate, sodium silicate, magnesium silicate, sodium metasilicate, and a combinations thereof.

14. A refill cartridge assembly comprising:
a refill cartridge configured to be housed within and aligned with a longitudinal axis of a spray wand, the refill cartridge having a distal and proximal end, wherein the proximal end comprises a swirl chamber that converts a single liquid stream flowing along the longitudinal axis of the spray wand into a plurality of cyclonic liquid streams flowing along the longitudinal axis of the spray wand that flow over and dilute the cleaning composition therein, and
a composition comprising chlorine contained in the refill cartridge of the refill cartridge assembly, wherein the composition is in a form of a solid chemistry.

15. The refill cartridge assembly according to claim 14 , wherein chlorine is selected from the group consisting of calcium hypochlorite; 1,3,5-Triazine-2,4,6(1H,3H,5H)-trione, 1,3-dichloro-, sodium salt, dihydrate (dichlor); 1,3,5-Trichloro-1,3,5-triazinane-2,4,6-trione (trichlor), chloramine-T hydrate, and a combination thereof.
