[001] An efficient spray applicator for universal usage

FIELD OF THE INVENTION

[002] The present invention relates to a spray applicator, and more particularly, to a spray applicator for efficient spraying of paint and/or coloring agents on non-round surfaces. The spray applicator has specific embodiments attached either on the outer frame of the round top of the container or inside the top for specific spraying.

BACKGROUND OF THE INVENTION

[003] Spray applicators are utilized for a variety of uses and purposes in real world. Most of these applicators embody adjustable spray applicators for varying or changing the direction from or location to which fluid from an attached nozzle needs to be sprayed.

[004] These spray applicators sprays various types of fluid, including paints, or different coloring agents in bursts of various geometric patterns.

[005] In spraying systems, nozzles determine the application volume at a given operating pressure, travel speeds, and spacing that break the liquid into droplets and form the spray pattern. It determines the amount of spray volume at a given operating pressure, travel speed, and spacing. Drift can be minimized by selecting nozzles that produce the largest droplet size while providing adequate coverage at the intended application rate and pressure. Selecting nozzles that produce the largest droplet size, while providing adequate coverage at the intended application rate and pressure, can minimize drift. The size of the spray particle is important because it affects both efficacy and spray drift of the application. All the spray applicators use conventional nozzles that entail inefficiency in their spray formation thus necessitating their modifications, which is attempted in the present invention.

[006] The present sprayer nozzles available in the market, are conical in shape and hence, cone nozzles yields complete spray coverage in a round or oval shape. This type of colouring is perfect, if the surface on which it is to be sprayed is round. But if the liquid or the color to be sprayed is on a non round surface, then the present applicators have specific disadvantages. In case of a non round surface, the application of colour becomes difficult since the sprayed colour may spill into the area which is either not required to be coloured or a different colouration is required. This can be applicable in case of colouring hair (non round surface) or any such surface which is not round in the edges. Particularly, in case of colouring hair, while spraying, the colours, usually gets spilled over to the scalp as well, which can be avoided by using the applicator of the present invention.

[007] To establish the uniqueness of the present innovation, a discrete survey of similar patents revealed the following:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[054] Referring to the drawings, wherein like reference numbers indicate like elements throughout the several figures, Figures 8 and 14 illustrates the isometric view of an applicator (10) for spray application having a flat panel body (12) having a proximal end (14) and a distal end (16). The said proximal end (14) of the said flat panel body (12) is structured as a connector in a circular shape forming a rim (22) having an inner surface (24) and an outer surface (26), wherein, the said inner surface (24) of the said rim (22) functions as a connector to be fitted perfectly with the lid of a universal sprayer (28). The said rim (22) of the connector is extended downwards to form a skirt (30) having a width of 10.30mm like the lid of a container without the top surface. The circular rimmed structure of the connector helps in mounting it with the outer surface of the lid of the sprayer as is depicted in Figure 8.

[055] The said circular rim along with the skirting can further be divided into a major arc portion (32), from where the said flat panel shaped applicator structure extends for spray application, whereas the minor arc portion (34) positioned diametrically opposite to the said applicator is left open, for easy adaptability with any sprayer bottle.

[056] The edge (20) of the distal end of the flat panel body is straight. The other two side edges (18), (18') of the panel are also straight and are devoid of any corrugations and design.

[057] The thickness of the flat panel body (12) is maintained at 0.76 mm. It will be known to those skilled in the art, that the width of the said flat panel, and the angle at which the spraying needs to be done are correlated. In the present embodiment the width is maintained at 36.70 mm.

[058] In an embodiment of the present invention, and referring to Figures 9 and 13, the radius of the inner surface (24) of the circular rim (22) of the proximal end of the panel is maintained at 15.02 mm and the radius of the outer surface (26) of the said circular rim (22) of the connector of the proximal end of the panel is maintained at 20.21mm.

[059] As depicted in figure 9, of the present embodiment, the opening of the said minor arc (34) of the said circular rim (22), which lies diametrically opposite to the said applicator (10), is maintained at 20mm. In this embodiment, the length of the said flat panel connector from the end of the nozzle at the distal end of the applicator till the centre of the circular rim (connector) of the applicator at the proximal end measures 86.80mm. The total length of the applicator measuring from the tip of the distal end of the applicator is maintained at 103.55mm as is illustrated in Figure 13.

[060] However, to those skilled in the art, it will be known that the length of the applicator will depend upon the object on which the liquid has to be sprayed, the type and purpose of spraying. Hence the length of the applicator can be varied accordingly.

[061] In another embodiment of the present invention, as illustrated in Figures 16 to 26, for mounting the spray applicator within the inner surface of the lid of the sprayer, the extended skirting of the said rim is provided with gaps (36) at intervals, which gives it broad tooth like structure (38) to be adapted to be fitted with the inner surface of the lid of the sprayer.

[062] In this embodiment of the present invention, the radius of the said inner surface (24) of the said circular rim of the said proximal end (14) of the panel is maintained at 10.10 mm and the radius of the outer surface (26) of the said circular rim of the connector of the proximal end of the panel is maintained at 13.95mm.

[063] Further, in the present embodiment, the opening of the minor arc (34) of the said circular rim (22), which lies diametrically opposite to the said applicator, is maintained at 10mm. In this embodiment, the length of the flat panel from the end of the nozzle at the distal end of the applicator till the centre of the circular rim of the connector of the applicator at the proximal end measures 86.80mm. The total length of the applicator measuring from the tip of the distal end of the applicator is maintained at 99.65mm.

[064] However, to those skilled in the art, it will be known that the length of the applicator will depend upon the object on which the liquid has to be sprayed, the type and purpose of spraying. Hence the length of the applicator can be varied accordingly.

[065] Further, the sprayer of the prior art applicators usually sprays the liquid in the form of an elliptical shape on the surface to be sprayed, which is perfect, if the surface on which it is to be sprayed is round. But if the liquid or the color to be sprayed is on a non round surface, then the applicator of the prior art has specific disadvantages. To obviate the disadvantages of the prior art, an angled applicator with edges of the applicator variously designed is proposed, which sprays the liquid as desired on the surface with a straight edge or edges shaped differently also prevents spilling of the sprayed material.

[066] Therefore, provided in this embodiment is an angled applicator. The flat panel applicator is designed to have an angle which is provided at a short distance from the proximal end of the applicator as shown in Figures 22-23 and Figure 24. The designing of the applicator at an angle from the circular rim of the applicator, prevents blocking of the sprayed material.

[067] Referring to Figure 27 through Figure 30, an embodiment of the present invention is shown, wherein the applicator can be folded at 90 degrees with respect to the nozzle of the sprayer or the connector of the applicator. The provision of an axle present at a short distance from the proximal end of the applicator helps the applicator to be folded.

[068] The edge of the distal end of the applicator is variable depending upon the texture or type of surface to which the spray is to be applied.

[069] Hence, in an embodiment of the present invention the edge of the distal end of the applicator is designed in a wavy form. This design is attained by an alternate concave (40) and convex (42) arrangement of the arcs, the radius of each arc being 1.20 mm. Each consecutive concave (40) or convex arc (42) is equidistant from each other. The distance from the centre of each concave or convex arc with respect to the next concave or convex arc is 3.40mm. Further the width between the crest and trough of the curves is maintained at 0.65 mm for optimized spraying function

[070] In another embodiment of the present invention, the edge of the distal end of the panel of the applicator is designed to form triangles, thereby providing it with pointed like structure.

[071] It is understood that the above description of the present invention is susceptible to considerable modification, change and adaptation by those skilled in the art, and that such modifications, changes and adaptations are intended to be considered within the scope of the present invention, which is set forth by the appended claims.
