[0003] The present invention relates to a formulation delivery system for use with an outdoor cleaning device, and more particularly, to a formulation delivery system having a solid chemical composition. Background Art

[0004] Outdoor cleaning devices use a hose end attachment that sucks a liquid formulation through a kettle - shaped container and discharges it outwardly from a sprayer device. The liquid formulation is sucked into the device, and then the liquid is diluted to a desired concentration and then applied to the exterior of a house, for example, to remove dirt and stains such as those caused by mold, algae, bacteria, and fungi. Most outdoor cleaning devices sold on the market for dirt and stains from mold, algae, bacteria, or fungi use liquid bleach - based products to apply the formulation. Some of the main drawbacks of such devices are the limitations of using only liquid formulations, the pressure loss in the water pressure caused by the suction and dilution required for liquid chemical compositions, and the fact that the containers are usually heavy and difficult to hold (1 gallon is nearly 10 pounds) to accommodate the volume of the container required to hold the liquid formulation. To address and solve these problems of consumers, alternative outdoor cleaning devices and formulation delivery systems are needed. Summary of the Invention

[0021] The following description of embodiments of the present invention is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. The following description is provided only by way of example with the aim of providing a disclosure enabling the implementation of the invention, but without limiting the scope or essence of the invention.

[0022] The present invention is a formulation delivery system for use with an outdoor cleaning device. The formulation delivery system includes a chemical composition in solid form. The composition of the solid chemical components of the present application has the ability to kill and clean mold, algae, bacteria, and fungi, for example.

[0023] In an embodiment of the present invention, the solid chemical component includes chlorine. Examples of chlorine-containing solid chemical components include, but are not limited to: calcium hypochlorite; 1,3,5-triazine-2,4,6(1H,3H,5H)-trione; 1,3-dichloro-; sodium salt; dihydrate (dichloroisocyanuric acid); 1,3,5-trichloro-1,3,5-triazinan-2,4,6-trione (trichloroisocyanuric acid); chloramine-T hydrate; and combinations thereof.

[0024] The solid chemical components of the present invention can be used in combination with other active and / or inert components, including but not limited to sodium sulfate, magnesium stearate, sodium bicarbonate, sodium metasilicate, sodium silicate, magnesium silicate, sodium carbonate, calcium chloride, calcium hydroxide, calcium carbonate, sodium chloride, water, and combinations thereof.

[0025] The use of the solid chemical components of the present invention eliminates the need for liquid chemical formulations. By eliminating the liquid formulations, the weight of the product is reduced, greater water pressure can be obtained from the consumer's home, and there is no restricted water flow as in other outdoor cleaning devices.

[0026] In an embodiment of the present invention, the solid chemical composition of the formulation of the present invention has a consistent and effective amount of chlorine to provide a killing and cleaning effect against molds, algae, bacteria, and fungi. By having the chemical composition in a solid form such as a tablet, it is possible to regulate the rate of dissolution of the solid and thus deliver a suitable amount of chlorine. The tablets are suitable for use in outdoor cleaning devices or in rods having a cartridge capable of accommodating the solid chemical composition.

[0027] The solid chemical composition of the present invention can be in any shape or form, including but not limited to round tablets, beads, cylindrical shapes, lollipop shapes (ridged circles), pellets, and combinations thereof. Figure 1A and Figure 1B Illustrated is the solid chemical composition of the present invention in the form of a solid tablet having a lollipop shape (ridged circle). The tablets can have different weights. For example, the tablets can have a weight in the range of 375 mg to 100 g. Preferably, the tablets have a weight in the range of 0.25 g to 3 g. However, tablets having weights outside of this weight range can still be contemplated for use in the present invention. For example, the total weight of the tablets used in a cylindrical cartridge is preferably in the range of 100 g to 500 g of the total weight of the solid tablets. The tablets can also vary in diameter. For example, the tablets can have a tablet diameter in the range of 0.125 inches to 2.75 inches. Figure 1C Illustrated is a variation in tablet diameter from 0.3125 inches to 2.75 inches and a variation in tablet weight from 375 mg to 100 g.

[0028] It is contemplated and within the scope of the present invention that the source of chlorine can be varied to obtain different levels of chlorine and different availability rates over time.

[0029] In an embodiment of the present invention, the solid tablets comprise calcium hypochlorite in the range of 40 wt% active to 75 wt% active and inert or other ingredients in the range of 25 wt% to 60 wt%. For example, inert and other ingredients such as sodium sulfate, magnesium stearate, sodium carbonate, sodium bicarbonate, sodium metasilicate, sodium silicate, magnesium silicate, calcium chloride, calcium hydroxide, calcium carbonate, sodium chloride, and water work well together to make solid tablets from 0.5 grams to 3 grams.

[0030] In an embodiment of the present invention, the solid tablet contains dichloroisocyanuric acid mixed with sodium sulfate and magnesium stearate in the range of 35% to 100% by weight of dichloroisocyanuric acid. Different ratios of dichloroisocyanuric acid and sodium sulfate change the dissolution rate of the tablet. To obtain optimal dilution from an outdoor spraying device or rod, the solid chemical composition can be used in parallel with a vortex generating device. Other combinations that can be used with dichloroisocyanuric acid can include, but are not limited to, sodium chloride, calcium chloride, sodium carbonate, sodium bicarbonate, calcium carbonate, sodium silicate, magnesium silicate, sodium metasilicate, and combinations thereof.

[0031] The solid chemical composition of the present invention is suitable for use with a spraying device or rod as shown in Figure 2 . Figure 2 is an isometric view of a spraying rod with a refill cartridge assembly according to the present invention. As shown in Figure 2 , the spraying rod 100 includes a spray nozzle 10, a spray body 12 shown in the shape of a tube, and a replaceable refill cartridge assembly 14 inside the spray body 12. The spraying rod 100 includes a non-disposable spray body 12 and a replaceable refill cartridge assembly 14, which has a refill cartridge for accommodating chemicals or chemical agents in solid form (also referred to herein as solid chemical composition). At the cut-off end or hose end of the spraying rod 100, the user connects a rubber hose with a rotating or swiveling hose nut to the hose nut 18 at the hose end. The user can open and close the fluid flow with a cut-off valve 20. The cut-off valve 20 is located on the handle 22 of the spraying rod 100. For example, the valve allows the user to turn off the water at the handle 22 during use and remove the spray body to replace the solid chemical composition or cartridge.

[0032] Water passes through the refill cartridge assembly 14 in a tangential swirling manner, surging or flowing through the solid chemical composition, maximizing exposure to the solid chemical composition, resulting in a higher concentration of the applied chemical composition. The chemical composition fluid mixture is dispensed at the distal nozzle 10. The user can rotate the nozzle 10 to select the desired spraying setting. Although two settings are shown, additional spraying settings can also exist and are within the scope of the present invention. The nozzle 10 preferably has one or more stop positions, more preferably four stop positions.

[0033] Figure 3 is a side view of a spraying rod with a Figure 2 refill cartridge assembly. In Figure 3 , optional molded gripping features 24 are shown on the spray body 12. By positioning the grip 24 on the spray body 12 rather than further down past the cut-off end, the torque on the user's arm is minimized, thereby reducing user fatigue. Figure 3The figure shows that the spray rod 100 includes a spray body 12. The spray body 12 is composed of a hollow tube, preferably transparent, which has an angled rod spray end 26 attached to a spray end selector or nozzle 10. Figure 3 Also shown are a shut-off valve 20 for controlling the water flow from the hose and a hose nut 18 for connecting to the hose. The spray rod 100 is particularly suitable for cleaning outdoor hard surfaces.

[0034] Figure 4 is a cross-sectional view of the spray rod 100 with a refill cartridge assembly 14. As Figure 4 shown, the external threads on the refill cartridge are screwed into the internal threads 32 of the handle at the cut-off end of the spray rod. Once the refill cartridge is fixed, the user screws the refill cartridge / cut-off assembly into the threads 34 of the spray body. At this point, the user rotates the shut-off valve 20 from the closed position to the open position and dispenses the product.

[0035] Figure 5 The figure shows the refill cartridge assembly 14. The refill cartridge assembly consists of a preferably transparent tubular refill cartridge 40 and a swirl chamber 42, which is snapped or otherwise attached or connected to the proximal end of the tubular refill cartridge 40. The refill cartridge 40 is hollow but is to be filled to accommodate a solid chemical composition. Preferably, the tubular refill cartridge 40 is pre-filled with a solid chemical composition. Water enters the proximal end, travels through the swirl chamber 42, the water surges tangentially or flows through the existing solid chemical composition, and exits through the orifice 44 at the distal end of the refill cartridge 40.

[0036] Figure 6 is a cross-sectional view of the refill cartridge assembly 14. Figure 6 The figure shows how the swirl chamber 42 is positioned within the refill cartridge. The swirl chamber 42 is inserted or pushed into the refill cartridge 40 until the swirl chamber 42 bottoms out on the shoulder(s) 46 of the refill cartridge 40. A fork or tab 48 extending as part of the swirl chamber 42 provides a one-way snap feature to engage with the refill cartridge 40 to prevent removal. It is also conceivable that the swirl chamber can be adhered to the cartridge using ratchet threads or other child-proof features.

[0037] The spray rod 100 generates a turbulent flow and / or a cyclone effect together with the water flow within the tubular body by using the swirl chamber 42 and redirects the water flow onto the solid chemical composition, so that the solid chemical composition is not diluted too quickly and the chemical concentration required for effectiveness is achieved. Changing the refill cartridge is used to meter the water flow rate to achieve proper dilution of the solid chemical composition. This is important for certain chemical products (such as products used to kill mold).

[0038] The benefits that the transparent refill cartridge offers to the user are that visibility allows the user to see the solid chemical composition dissolve and also know when to replace the solid chemical composition and / or the refill cartridge. The top of the refill cartridge has holes that are small enough to prevent beads from clogging the outlet orifice, but the water passing through the outlet orifice is uninterrupted. Another benefit is that the user does not need to come into contact with the solid chemical composition, which may be toxic or in a concentrated solid form. The screw / thread connection of the refill cartridge assembly to the handle of the spray bar allows water to pass through the refill cartridge to appropriately dilute the solid chemical composition.

[0039] Figure 7 The swirl chamber 42 is illustrated. The swirl chamber 42, having a front side 44 and a rear side 46, creates fluid turbulence within the refill cartridge. In the absence of swirl and turbulence of the water, the water would pass directly through the refill cartridge and result in a lower concentration of the chemical. The water enters in a linear fashion onto the rear side 46 of the swirl chamber 42. The swirl chamber causes a change in direction and the fluid exits in a tangential manner. Potential swirl chamber configurations can include one or more tangential channels 48, preferably two or more tangential channels 48. The channels 48 can have various geometries, such as rectangular or helical. Providing spacing between the channels results in greater tangential forces; however, it may or may not result in a greater concentration. The swirl chamber has one or more raised protrusions 50 having fluid outlet windows 52, and the fluid outlet windows can be rectangular, square, circular, or another shape. As illustrated, a rectangle is shown. The swirl chamber can have various configurations. Considerations in selecting the configuration include, but are not limited to, suitability for the injection molding process and a cross-sectional flow area that does not restrict fluid flow.

[0040] During use, water passes through the swirl chamber and creates a swirl or vortex. The swirl chamber helps prevent the chemical from being released too quickly or depleted too rapidly. It is used to mix the water and the dissolved chemical (preferably in a uniform ratio).

[0041] As noted above, the swirl chamber 42 can have alternative configurations and still be within the scope of the present invention as long as the configuration creates a swirl or vortex of the water as it passes through the swirl chamber. For example, the water enters as a stream and creates several streams in one direction to create a swirl or cyclone effect.

[0042] Figure 8 is an illustration of a spray bar device according to the present invention adapted to receive a solid chemical composition within a refill cartridge assembly. Figure 8 illustrates the solid chemical composition housed within the refill cartridge of the spray bar device.

[0043] The use of solid chemical components enables the design of lighter products for the end - consumer and reduces the use of water restrictors required in existing outdoor cleaning devices. Since water restrictors are not needed, the device can shoot farther and has greater power. With these benefits, consumers can clean or treat a wider range of outdoor surfaces, such as high windows, second - story surfaces, gutters, etc. The solid chemical components also allow consumers to have some control over the dilution and thus the strength of the substance coming out of the device. If consumers allow the solid chemical components to dissolve in the system for a longer time, they will have a more concentrated or “super - charged” amount of chlorine to remove their heavier stains.

[0044] The formulation delivery system of the present invention can be used with hydantoins to provide cleaning and bleaching efficacy. Hydantoins are organic compounds that release halogen bleaches when dissolved in water. Examples of such compounds that can be used in combination with a refill cartridge and / or a spray wand include, but are not limited to, bromo - 1 - chloro - 5,5 - dimethylhydantoin, dichlorodimethylhydantoin, dichloroethylmethylhydantoin, and combinations thereof. It is contemplated and within the scope of the present invention that these compounds can be used in the formulation delivery system to achieve external cleaning of mold, algae, bacteria, fungi, and, when combined with other ingredients, can provide benefits in outdoor cleaning. Some combinations of hydantoins used with other ingredients include the use of sodium citrate, anionic surfactants such as alkylbenzene sulfonate and sodium dodecyl sulfate, sodium carbonate, hydrated silica, sodium chloride, etc.

[0045] The refill cartridge assembly can include a refill cartridge and a composition of a hydantoin compound housed in the refill cartridge of the refill cartridge assembly, wherein the composition is in the form of a solid chemical component.
