DETAILED DESCRIPTION

(10) One example of a funnel-bottomed bucket in accordance with the present invention is illustrated in FIG. 1. A paint bucket 110 may comprise an interior 112 that holds a certain volume of paint, for example, a bucket may provide an interior that holds five gallons of paint or other liquid. However, bucket 110 may comprise any size or volume of bucket, whether designed specifically to hold paint or for general use. The bucket 110 may have a top diameter 160 and a bottom diameter 150. If the bucket walls are straight, the top diameter 160 and the bottom diameter 150 may be the same, while if the bucket 110 is flare sided the top diameter 160 may be greater than the bottom diameter 150. A bucket 110 may have a first paint level 114 when full but a second paint level 116 after most of the paint within bucket 110 is consumed by power painting system 180 (described further below). Of course, paint levels other than first paint level 114 and second paint level 116 will exist when buckets in accordance with the present invention are used, and the level may eventually be lower than exemplary second paint level 116, even to the point of being at a level within the recess provided at the bottom of the exemplary bucket 110, which shall be described further below.

(11) Because a relatively small amount of paint may fill the recess containing the nozzle of a sprayer system 180, almost every bit of paint contained within bucket 110 may be used without having to reposition bucket 110 or the nozzle of power painting system 180. A recess, shown in the example of FIG. 1 as cylindrical, may have a diameter of 120 that corresponds to the diameter of a nozzle used by the power painting system 180 to extract paint from the bucket 110. The angled sides of the funnel bottom, which shall be described more fully below, may slope at an angle 140 to cause paint to flow into the recess as the level of paint within the bucket 110 lowers. The top of the recess may correspond with the bottommost edge of the angled side of the funnel bottom. The recess may have a height 130 sufficient to retain the nozzle of a power painting system 180 within the recess.

(12) FIG. 2 illustrates one example of a power painting system 180 having a nozzle 210 that may be used in conjunction with buckets in accordance with the present invention. At least one aperture 220 within nozzle 210 may permit paint to be drawn into nozzle 210 for application by a painter. Screens and/or filters may be provided as part of or in conjunction with nozzle 210 to protect the painting system 180 from debris that may be contained in paint. A rigid pipe 250 may deliver paint to a hose that ultimately delivers paint to a sprayer, roller, or other paint application tool under the control of a powered pump system (not shown). The pipe 250 may be coupled to nozzle 210 using a coupling 240 that affixes pipe 250 to the head 230 of nozzle 210. Nozzle 210 may have a diameter of 222 that is smaller than the diameter 232 of head 230. Diameter 222 of nozzle may be the basis of selecting the diameter of a recess used in a funnel-bottomed bucket in accordance with the present invention.

(13) FIG. 3 illustrates an example of a nozzle 210 inserted into a recess within a funnel-bottomed bucket 110. As can be seen in the example of FIG. 3, the diameter of nozzle 210 is slightly less than the diameter of the recess, permitting nozzle 210 to be snugly but removably inserted into the recess without blocking the flow of paint down the inclined walls of the funnel bottom and into the recess. In some examples, the diameter of the recess may be sufficiently larger than the diameter of nozzle 210 to permit nozzle 210 and pipe 250 to be oriented at an angle other than substantially vertical.

(14) FIGS. 4A and 4B illustrate additional properties of an exemplary recess 410 within a bucket 110. Recess 410 may be defined by a sidewall 412 that extends circularly defining the perimeter of recess 410. Recess 410 may have a bottom 420, with bottom 420 corresponding to the lowest level to which paint within bucket 110 may flow when the bucket 110 is in an upright orientation. Recess 410 may have a cylindrical shape (as depicted in the example of FIG. 4A), a truncated conical shape (as depicted in the example of FIG. 6), or other geometric shapes.

(15) An angled funnel wall 414 may define a funnel having a desired angle to cause paint within bucket 110 to flow into a recess, such as recess 410, as the paint level within bucket 110 reduces. Funnel wall 414 may be configured with an incline of a few degrees to several degrees relative to horizontal, such as between three and forty-five degrees or between five and thirty degrees. A space 460 beneath the angled funnel wall may be solid or hollow, but will not contain paint while the bucket 110 is in use. In some examples, funnel wall(s) and/or recesses may be created within a pre-existing bucket using an insert that may be engaged in the bottom of a bucket having a flat bottom.

(16) Referring now to FIG. 5, further aspects of an exemplary funnel-bottomed bucket 510 that may hold paint within its interior 505 in accordance with the present invention is illustrated. A recess 515 at the bottom of a funnel shape may be cylindrical in shape. By being cylindrical in shape, recess 515 may possess a top diameter 520 equal to its bottom diameter 530.

(17) Meanwhile, FIG. 6 illustrates an example of a bucket 610 having an interior 605 to retain a volume of paint wherein the recess 615 has a partially conical shape, i.e. a truncated cone. Recess 615 has a conical shape in the sense that top diameter 620 is smaller than bottom diameter 630 of recess 615. In examples, top diameter 620 may be slightly greater than the anticipated diameter of an intake nozzle of a power painting system. By flaring out at the bottom, recess 615 may receive a nozzle inserted past the top of the recess 615 and permit the nozzle assembly to tilt or lean within recess 615 while the power painter is in use. By leaning the nozzle and pipe of a power painting system, the bucket and/or power painting system may be less likely to tip due to the pulls or tugs that may naturally occur during the painting process.

(18) FIG. 7 illustrates one example of a nozzle 210 inserted into a recess with the pipe 250 of the power painting system leaned against a sidewall of bucket 710. By selecting appropriate dimensions for a recess, a cylindrical recess may be sufficiently larger than the diameter of nozzle 210 to permit the power painting system to lean while nozzle 210 remains within recess. In other examples of a conically shaped recess, the upper diameter of the recess may hold a nozzle securely but removably while the wider diameter of the bottom of the recess may permit the nozzle to lean and, along with the nozzle, the pipe 250 and other components of the power painting system.

(19) While funnel-bottomed paint buckets in accordance with the present invention may be constructed with a funnel portion integral to the bucket, in other examples a funnel-shaped bottom in accordance with the present invention may be inserted into pre-existing paint buckets (or other types of buckets) and, optionally, withdrawn and reused after painting with that bucket has been concluded. For example, as depicted in FIG. 8 a bucket 810 may receive a funnel-shaped assembly 820 having a seal 830 around a perimeter edge of the funnel-shaped bottom 820 to create a tight seal between the interior walls of bucket 820 and the funnel-shaped bottom 820. A seal 830 may comprise a silicone or rubber flange, a gasket, or any other structure that firmly contacts the interior sidewall of a bucket to prevent paint from leaking between the funnel-shaped bottom 820 and the sidewall of the bucket 810. In some examples, a seal 830 may be omitted entirely As shown in phantom, in manners similar to those described above, a funnel-shaped insertable bottom 820 may provide a recess and angled funnel sidewalls that direct paint to the recess when the funnel-shaped bottom 820 is installed within a bucket 810.

(20) Systems and methods in accordance the present invention are not limited to any particular size or type of bucket or other paint container, nor are they limited to any given type of power painting system or nozzle assembly. Exemplary diameters for a top and/or bottom of a recess within a funnel bottom in accordance with the present invention may range from about 1.5 inches and 2.5 inches, although other dimensions may be used. In many examples, a power painter nozzle may have standardized dimensions and a funnel bottom for a paint bucket in accordance with the present invention may provide a recess having dimensions adapted to receive and retain standardized nozzles. In other examples, nozzles and recesses may be formed to more effectively mate during use. In some examples, polygon shaped recesses rather than circular recesses may be used, particularly if a polygon shaped nozzle is used. Further, the angle of the funnel wall may vary. The viscosity of different types of paint may differ and, accordingly, the angle of the funnel walls of a bottom in accordance with the present invention may be selected in order to encourage a wide range of viscosities of paint to flow into a provided recess for uptake by a power painter nozzle.

(21) Whether formed as discrete funnel bottom for insertion into pre-existing paint buckets or formed as an integral paint bucket having a funnel-shaped bottom, the present invention may be formed using various types of materials using various fabrication techniques. In many examples, a plastic may be injection molded to form a bucket and/or funnel bottom for a bucket. In other examples, metals, nylons, resins, and other materials may be used to form systems in accordance with the present invention through molding, casting, machining, or any other technique.
