Multiple pigment application pencil column and pencil slice

A pigment application pencil includes a pencil column or a pencil plate of pigment material having a composition which readily rubs onto a contacting surface and being divided into several discrete color regions of differing pigment color, the column having at least one longitudinal flat side including portions of at least two of the color regions; so that sliding contact of two color regions on the flat side permits even and uniform parallel application of contrasting pigments along a well defined straight or curving line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. Reference is now made to the drawings, wherein like characteristics and features of the present invention shown in the various FIGURES are designated by the same reference numerals. First Preferred Embodiment Referring to FIGS. 1 - 10 , a pigment application pencil 10 is disclosed, including a column 20 of pigment material having a composition which readily rubs onto a moving, contacting surface S such as of human tissue and is divided into discrete color regions 22 of differing pigment color, the column 20 having a column side wall formed of at least one longitudinal flat column side wall segment 24 including portions of at least two of the regions 22 , and an optional outer layer 40 of pencil cover material. The discrete color regions 22 are preferably, although not necessarily, divided from each other along radial column 20 lines. Exposure of two or more color regions 22 on a single flat column side wall segment 24 permit even and uniform parallel application of contrasting pigments along a well defined straight or curving line L. The column is preferably unified and singular, but alternatively may be a bundle of pigment material sticks of differing colors. The pigment material is preferably eyeliner or lipliner, but may be any of many other pigment materials such as crayon material. The pencil cover material is preferably wound paper or plastic which is progressively unwound by hand at intervals in which the pigment material is worn flush with the cover material. The unwinding cover material at the distal end of the pencil leaves a substantially conical outer layer shape, as is known in conventional wax pencil design. The circumference of unified column 20 preferably consists entirely of such flat column side wall segments 24 intersecting at sharp corners 26 , the preferred column 20 cross-sectional shapes including but not limited to triangular, square, pentagonal and hexagonal. A single narrow line of pigment material can be applied by dragging a corner 26 over a surface to be marked. These general geometric shapes are still preferably truncated at longitudinal corners 26 to provide alternating long flat column side wall segments 24 which can be dragged over a surface to be marked to produce pigment lines of full width and short flat sides 32 , which can be dragged over a surface to be marked to produce pigment lines of medium width. Thus a triangular cross-section becomes a triangle truncated at each corner 26 so that each corner 26 ends in a longitudinal short flat side 32 . See FIGS. 1 and 9 . Second Preferred Embodiment A second embodiment is provided in the form of a pencil plate 100 , also referred to as a pencil slice, which essentially is a cross-sectionally cut and diametrically enlarged segment of a pencil column 20 of the first embodiment, omitting outer layer 40 of cover material. See FIGS. 11 - 23 . Each pencil slice 100 preferably is large enough to be gripped between user fingers while protruding outwardly from between the user fingers for rubbing, and is formed of pigment material and has a first slice face 102 and a second slice face 104 and a circumferential or parametric plate side wall 110 following any one of many possible geometric shapes. See FIGS. 15 - 23 , which illustrate examples of such circumferential side wall 110 geometric shapes. As in the first embodiment, the pigment material preferably has a composition which readily rubs onto a contacting surface S such as of human tissue, or paper or other materials and is divided into discrete color regions 22 of differing pigment color, the circumferential side wall 110 has at least one longitudinal flat side wall segment 24 including portions of at least two of the regions 22 . A selected flat plate side wall segment 24 or, curved side wall segments 28 of circumferential side wall 110 are rubbed against a contacting surface S to leave a trail of color matching that of the pigment of the corresponding region or regions 22 . Alternatively, first slice face 102 or second slice face 104 may be rubbed against a contact surface S for a broad, mixed or multiple pigment trail of color. And once again, as in the first embodiment, the discrete color regions 22 are preferably, although not necessarily, divided from each other along radial lines. Exposure of two or more color regions 22 on a single flat plate side wall segment 24 permit even and uniform parallel application of contrasting pigments along a well defined straight or curving line L. The pencil plate 100 is preferably unified and singular, but alternatively may be a bundle of pigment material fragments of differing colors. The pigment material is preferably eyeliner or lipliner for cosmetic use, but may be any of many other pigment materials such as crayon material for cosmetic or for school or play use by children. The pencil plate 100 is well suited to child use because the corners, even sharp corners, are safe because the pigment material selected normally is soft. The circumference of unified pencil plate 100 optionally consists entirely of such flat plate side wall segments 24 intersecting at sharp corners 26 , the preferred pencil plate 100 cross-sectional shapes including but not limited to triangular, square, pentagonal, star and hexagonal or includes curved plate side wall segments 28 , including but not limited to circular, heart and flower shapes. A single narrow line of pigment material can be applied by dragging a corner 26 or curved plate side wall segment 28 over a surface to be marked. Flat plate side wall segment 24 geometric shapes once again are preferably truncated at longitudinal corners 26 to provide alternating long flat plate side wall segments 24 which can be dragged over a surface to be marked to produce pigment lines of full width and short flat sides 32 , which can be dragged over a surface to be marked to produce pigment lines of thin, wide or medium width. Thus a triangular cross-section becomes a triangle truncated at each corner 26 so that each corner 26 ends in a longitudinal short flat side 32 . While the invention has been described, disclosed, illustrated and shown in various terms or certain embodiments or modifications which it has assumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
