DETAILED DESCRIPTION OF THE DISCLOSURE

The present invention solves the problems described above by combining multiple specific functions into one tool for cleaning fingers. As used herein, the term “finger” includes all types of fingers including the thumb, index, middle, ring and pinkie fingers. The term “finger” also includes the skin, nail, nail bed and cuticle.

Functions of the present invention may include filing, scrubbing, and/or cleaning and may be combined in any number of ways. Referring to FIG. 1, a first function may be accomplished by providing a center aperture 100 rimmed with bristles to form bristle component 110. The bristles preferably extend radially inwardly into the aperture 100 and have innermost ends that define a finger-hole preferably sized to be smaller than an average adult male's smallest finger. This feature may be designed such that a finger may be inserted through the aperture to scrub the circumference of the finger by rotating or twisting the finger within the aperture.

Different bristle materials or shapes may be used in the present invention to create bristles for specific cleaning environments. In one embodiment of the present invention, the bristles are made from a highly durable polypropylene resin. Examples of appropriate resins include, but are not limited to, TPE, TPU, Santoprene, natural latex rubber, polyethylene, polypropylene or nylon. In an alternative embodiment, tufted natural bristles may also be used, such as boar hair. A preferred resin may be a blend of PE and EVA. The shape of the bristle is also important to the present invention because it also helps to control the amount of tension the bristle places upon the finger. In a preferred embodiment, the bristle may be triangular when viewed in a cross-sectional view. Additionally, the bristles should be of a comfortable texture and tension to the user. In one embodiment of the present invention, the bristles are tapered such that the constrained end of the bristle is thicker than the free end of the bristle. In another embodiment of the present invention, the bristle may have a rounded or flat tip.

In a preferred embodiment, shown in FIG. 1, multiple rows of bristles may be aligned parallel to one another or spaced in various patterns such that a maximum scrubbing efficiency may be achieved. In a particular embodiment, the bristles are preferably positioned in an alternating pattern between each bristle row to allow bristles to be placed in the open areas of the adjoining row of bristles. Each bristle may be spaced about 3 mm from center to center. The next row may also have similar placement, but be positioned such that they are placed in the approximate 3 mm gap of the adjoining bristle row such that the spacing between rows of bristles is about 1.5 mm as shown in FIGS. 1 and 8. Referring to FIG. 8, the bristles may be constructed in an assembly such that three separate rings of bristles 120, 130 and 140 are placed on top of each other to provide multiple rows of bristles. In this assembly, the rings of bristles 120130 and 140 may be notched or tabbed to snap together, forming a single 3-row bristle component 110. The length of the bristles may also be varied to provide a different scrubbing experience.

A second function provided by the present invention may be accomplished by providing shorter scrubbing bristles, as shown in FIG. 2. Such bristles are preferably located along one or more of the outer edges of the multi-tool. Outer bristles 200 may be designed to scrub dirt and grime from underneath the fingernail or for more detailed, local scrubbing of the finger nail or cuticle area. Outer bristles 200 are preferably made from similar materials as bristle component 110. In additional embodiments, the bristles may be made of an alternate material than used in bristle component 110. The bristle density of shorter bristles 200 may also be designed in parallel rows, as shown in FIG. 4 In an alternative embodiment, outer bristles 200 may be arranged in an alternating pattern such that they are positioned approximately 1.5 mm from center to center.

A third function provided by the present invention is a sharp or pointed tip component 300 that may be used to remove dirt from under the fingernail or to push the cuticle back. Tip component 300 may also be used to scrape paint or other similar substances off of the finger, fingernail surface, or around the cuticle area. The tip is preferably located at a junction of two sides of the tool and is made of the same material as the tool for simpler manufacture.

A fourth function provided by the present invention may be a nail file component 400, which is preferably located around part of or the entire perimeter of the tool. The nail file surface is preferably designed to file a finger nail edge to soften or contour the finger nail edge. The material used for nail file component 400 may be of any material with a sufficient grit to file fingernails, such as an etched metal or a plastic resin with embedded grit. A preferable grit surface texture ranges from about 100 sand paper grit to about 200 sand paper grit.

The finger cleaning multi-tool of the present invention may be of any shape and size that is appropriate for the aforementioned uses. The tool may be formed from any material that is durable and capable of being molded. In one embodiment of the present invention, many of the components may be made from metal. Outer nail file components or plates (shown in FIGS. 5, 6, and 7) may be stamped out of metal such as stainless steel, chrome treated carbon steel, or painted carbon steel. Upper plate 500 and lower plate 600 preferably sandwich the nail file component 400, bristle component 110 and outer bristles 200 located along the tool face. In such an embodiment, tip component 300 may be integral to upper plate 500 with a more polished, sharpened finish. The bristle and nail file components may be locked in the appropriate position by spot welding the upper plate 500 and lower plate 600 together to trap the other components. Additionally, a metal wedge locking mechanism or a snap feature stamped within the metal components may be used. Bristle component 110 may be constructed from a TPE or polypropylene material in a circular arrangement adapted to be snapped over a ridge in either side of the metal plates that form the larger surfaces of the tool.

In another embodiment of the present invention, upper plate 500 and lower plate 600 may be made of a polycarbonate resin material. In this embodiment, bristle component 110 and outer bristles 200 may be manufactured in a polyethylene resin. File component 400 may be made with Acrylonitrile Butadiene Styrene (ABS) resin that may be subsequently coated with a translucent sandy grit, preferably suspended in an adhesive resin that allows secure attachment to the ABS substrate. Tip component 300 may also be made of a polycarbonate resin material that may be polished or buffered for a different finish than that of the multi-tool from the flash line to the end of the tip. In another embodiment of the present invention, the surface of the tool may be textured to improve grip and/or control of the tool. Exemplary surface treatments may include finger concavities for finger placement, stamped surface textures to improve grip, or soft surface textures to enhance grip. Santoprene or TPE resins may be over-molded onto the tool or attached through the use of adhesives.

In a preferred embodiment, the polycarbonate (PC) plates 500 and 600 sandwich file component 400 and bristle component 110 and may be injection molded. In this embodiment, tip component 300 may be integral and formed as part of upper plate 500. Upper plate 500 and lower plate 600 may be molded with attachment features that utilize friction or sonic welding to secure the assembled components together. In an alternative embodiment, an adhesive may be used to secure the assembled components together. In a specific embodiment shown in FIG. 8, upper plate 500 may be manufactured such that it has multiple circular protrusions 550 that are adapted to connect to multiple opposing circular indentations 650 to secure plates 500 and 600 together via a friction fit. These indentations and protrusions may be of any shape and number to secure plates 500 and 600 together. In other embodiments, the components may be welded together by a process appropriate for plastics. Bristle rings 120, 130 and 140 may include tabs 150 to align the components together and align assembled bristle component 110 into the adjoining upper and lower plates 500 and 600.

Nail file component 400 may also contain features that allow for alignment within the assembled tool. For example, nail file component 400 may have indentations 450 that are adapted to surround circular protrusions 550 and circular indentations 650.

Although the present invention has been described with reference to specific examples, which are intended to be illustrative only and not to be limiting of the invention, it will be apparent to those of ordinary skill in the art that changes, additions or deletions may be made to the disclosed embodiments without departing from the spirit and scope of the invention. For example, although center aperture 100 is described in one embodiment as being circular, it may be of any shape. Any components such as bristle rings, for example, may then be of any shape to conform to the additional aperture shapes and the like.
