    FIELD OF THE INVENTION
    [001] The apparatus refers, in general, to razor blades or shaving, and more particularly, to innovative coatings on the edges of razor blades or shaving. BACKGROUND OF THE INVENTION
    [002] Current razor or shaving blades include a sharp substrate, such as stainless steel, one or more rigid coatings to optimize edge strength, tip shape, wear resistance, etc. layered on stainless steel and a soft coating, usually of polymeric material, such as telomer, layered on the rigid coating to provide lubricity.
    [003] It is well known that the combination of a sharp blade profile and rigid and slippery coatings generally define the performance of the blade element. Coating options that can improve the hard coating performance of a blade element and / or increase blade lubricity are generally of interest.
    [004] It would be desirable to optimize the blade coatings and / or steps required in the production of the blade, while maintaining or improving the performance of the blade. SUMMARY OF THE INVENTION
    [005] According to the invention, a razor or shaving apparatus includes a sharp substrate having at least one layer of BAM material disposed thereon. In a preferred construction of the present invention, at least one layer of BAM material is directly disposed on the sharp substrate. One or more intermediate layers can be disposed between the BAM layer and the sharp substrate and one or more layers of outer coating can be disposed on the BAM layer. The intermediate layer and the outer coating layer include an adhesion layer that can be composed of niobium, chromium, platinum, titanium, or any combination or alloys thereof.
    [006] In one embodiment of the present invention, at least one polymeric material is disposed on at least one layer of BAM, on said one or more intermediate layer, or on said one or more layer of external coating, or any combination of the same. The polymeric material includes polytetrafluoroethylene (PTFE) or a material with a higher or lower friction coefficient than that of polytetrafluoroethylene (PTFE).
    [007] The outer coating layer of the present invention can include a BAM composite and a second component. The second component could be a polymeric material.
    [008] In another aspect of the present invention, the outer coating layer includes an increasing concentration of the second component (for example, the polymeric material) towards an external surface of the substrate or a decreasing concentration of the second component (for example, polymeric material ) towards an external surface of the substrate.
    [009] The at least one BAM layer of the present invention is disposed on the sharp substrate by physical vapor deposition, such as magnetron ion bombardment, chemical vapor deposition, or any combination thereof.
    [0010] The sharp substrate can include stainless steel, metal, ceramic, composite, plastic, glass, or any combination thereof.
    [0011] In a preferred aspect of the present invention, the sharp substrate is on a razor blade or shaving edge. The edge of the blade could be linear, non-linear, or any combination thereof.
    [0012] In another aspect of the present invention, the BAM layer provides antimicrobial properties.
    [0013] In an alternative embodiment of the present invention, a razor or shaver includes a component having at least one layer of BAM material disposed on it. The component can be a non-cutting element, a cutting element. The non-cutting elements contemplated by the present invention include a cartridge or cable component, such as a clip on a wet shaver or shaver, or an external or internal surface of a metal foil disposed on a dry electric shaver or epilator. The cutting element could be a cutting element on a dry electric shaver or shaver or a razor blade or shaving edge on a wet shaver or shaver.
    [0014] A method of making a razor or shaving blade includes providing a sharp substrate and depositing at least one layer of BAM material on an external surface of the substrate.

    [0022] This invention relates to an innovative application of ceramic coatings based on magnesium borate and aluminum (AlMgB14, also known as BAM) for surfaces of shaving or shaving components and in particular for razor blade edges. shave or shave, as described here. Applicants are not aware of BAM materials being used or suggested for use with razors or shaving blades. The high or low friction properties of the BAM coating can provide significant benefits in shaving or shaving blade edges, as these coatings can increase blade performance and / or simplify the manufacturing process.
    [0023] The basic BAM material usually contains elemental aluminum, magnesium and boron. The terms "BAM" or "BAM material" or "BAM layer" or "AlMgB14" or "BAM based" or "BAM alloy" or "BAM-type" will generally be used interchangeably here and may mean the material based on AlMgB14 itself, a derivative of the material such as metal boride XYB14, where X and Y are metal atoms, or the composite material of AlMgB14, base or XYB14, combined with a variety of additives, alloys, or uni agents or multi elements that can have an impact on their properties. BAM without additive components is sometimes called a base or baseline level material to distinguish it from a BAM material containing second phase or solid solution additives or other elements. Additives can generally include, but would not be limited to, components such as silicon, carbon, titanium diboride (TiB2), aluminum nitride (AlN), boron nitride (BN), and / or alloying agents.
    [0024] BAM (AlMgB14) is a chemical product of aluminum, magnesium and boron, and is a ceramic alloy that is generally highly resistant to wear with a low coefficient of friction. It should be noted that the BAM material can generally become more rigid when certain elements or compounds are added to the basal level BAM material. For example, basal-level BAM material can typically exhibit micro-stiffness from about 32 GPa to about 35 GPa, but additions such as titanium diboride (TiB2) can increase the micro-stiffness to about 45 GPa producing one of the most mass-produced materials known hard drives. BAM materials demonstrated some of the lowest friction coefficients of solids currently known (for example, less than 0.05 and as low as about 0.02) as revealed in Eaton Corporation's Final Technical Report entitled Nanocoatings for High-Efficiency Industrial Hydraulic and Tooling Systems , Award No. DE-FG36-06GO16054, dated December 31, 2010, while the known friction coefficient for Teflon (eg PTFE) widely used in razor blades or hair removal as coatings to provide lubricity is generally known to be in the range of about 0.05 to about 0.10.
    [0025] Consequently, a coating on a razor or shaving blade comprising BAM has the potential to exceed the functionality of current discrete rigid & slippery coatings (eg low friction) applied to razor blade edges in a single coating application. . Since BAM coatings will generally be both rigid and low-friction (for example, slippery), they can desirably provide a single coating solution for blade edges. The need for a smooth, slippery outer coating layer and / or other intermediate layers such as adhesion layers or the like, may or may not be desired, depending on the desired blade edge attributes and characteristics of the applied BAM coating. Having no additional layers potentially eliminates the processing steps required for these layers (eg, spray & sintering, telomere thinning), resulting in simplified manufacturing while potentially producing a product with improved performance.
    [0026] Furthermore, the very rigid nature of BAM coatings could result in several improvements to the blade. BAM coatings applied to standard sharp blade substrates or geometries can perform better than today's rigid coatings providing improved edge strength and wear resistance. BAM coatings can also be applied to different blade profiles, which can result in further optimized blade performance.
    [0027] The apparatus for processing slides with BAM material desirably includes processes that are currently used, that is, physical vapor deposition (PVD), such as ion bombardment by magnetron, however other feasible methods known in the art as chemical deposition of steam (CVD) are also contemplated as processing techniques applicable in the present invention. While stainless steel is the desired substrate of the present invention, as is the common substrate for razor blades or razor blades, blade substrates composed of another metal or metals, ceramic, composite, plastic, glass, or any other combination thereof, are also contemplated in the present invention. Coatings of BAM material, when applied to other razor or shaving cartridge components, can improve wear and / or slip resistance during shaving or waxing, particularly if arranged in clips or other skin management components and / or hair.
    [0028] The term "shaving or shaving blade" in the present invention desirably means a "substrate" composed of stainless steel that includes a blade body and at least one flank. Desirably, a razor or shaving blade includes two flanks forming a blade edge and a blade body. The two flanks intersect at one point or end, or what is often called the definitive end. Each flank can have one, two or more chamfers. The blade body is usually the remaining area of the razor or shave below the flanks or chamfers. As shown in a quote box in Figure 1, blade 14 includes blade body 29, two chamfers 28 for each two flanks 27 that intersect at end 23 forming a blade edge 14a. A "substrate" means the substance or material modified in the present invention. Illustrative modalities here relate to a stainless steel substrate commonly used for shaving.
    [0029] Moving now to Figure 1, a razor or shaver 10 generally includes a shaving or shaving unit or cartridge 16 attached to a handle 18 with the shaving or shaving unit 16 having one or more blades 14 (for example , 3 blades shown) each with a sharp edge 14a according to the present invention. A cap 12 and a guard 13 can also be included in the shaving or shaving unit 16, the cap 12 preferably including a shaving aid or shaving composite 12a attached to it. The shaving or shaving unit 16 can be adapted for coupling and uncoupling the handle of the shaver or shaving 18 so that a new cartridge unit 16 can be attached to the handle when the blades become blunt or can be integral with a handle 18 so that the complete shaver or epilator 10 is discarded when the blades become blind. It is observed that one or more of the blades 14 in Figure 1 have a BAM material disposed on them, preferably in the region of the blade edge.
    [0030] A diagrammatic view of a blade or sharp substrate, and in particular the edge region of blade 20 of the edge of blade 14a of Figure 1, is shown in Figure 2 of the present invention. The blade includes a stainless steel substrate 22 with a sharp edge formed in a sequence of sharpening operations that form a portion of the end 23 with a radius typically less than 500 angstroms and end flanks 27 that may or may not include one or more chamfers 28 as shown in the quotation box of Figure 1. Deposited at the end 23 and flanks 27 of the substrate 22 is at least one layer of BAM material 24 according to a preferred embodiment of the present invention. The thickness of the BAM material 24 may desirably range from about 300 angstroms to about 5000 angstroms and preferably in the range of about 500 angstroms to about 1800 angstroms, and may or may not be deposited uniformly across the edge and flanks. It should be noted that the BAM material can be deposited regardless of any variation in flank lengths 27, angles, and aspect ratios (for example, the ratio of the distance from the end portion of the blade 23 to the end BAM 26 and the coating width of BAM material 24 at the end portion 23).
    [0031] The BAM coating can extend from the definitive end to any length along the flanks of the blade 27 edge and may or may not extend to the blade body 29.
    [0032] As noted above, the apparatus for processing blades of this type may desirably include magnetron ion bombardment while other methods feasible in the art are also contemplated as processing techniques applicable in the present invention.
    [0033] In addition, due to the presence of boric acid molecules on the outer surface 24a of the BAM layer 24, the BAM layer 24 can inherently provide antimicrobial properties ostensibly acting as a barrier to the growth of bacteria, fungi, and other microorganisms on the razors or shavers themselves, which in turn provide a clean blade for a user's skin.
    [0034] In a first alternative embodiment of the present invention, Figure 3 shows a cutting edge region of the blade 30 having one or more intermediate layers 36 arranged between a coating of BAM material or layer 34 and a stainless steel substrate 32. A intermediate layer 36 may desirably include an adhesion layer which may include niobium, chromium, platinum, titanium, or alloys of the above and / or any combination thereof. The intermediate layer 36 can have a thickness of about 200 to about 400 angstroms. The intermediate layer 36 can be desirably arranged between the substrate 32 and the coating of BAM material 34 to assist in the adhesion of the BAM coating 34 to the substrate 32.
    [0035] In a second alternative embodiment of the present invention, Figure 4 shows a region of blade edge 40 with one or more layers of outer coating 49 disposed on the layer of BAM material 44 which is disposed on the stainless steel substrate 42 In the present invention, the outer coating layer 49 (and other polymeric layers described here) may desirably be comprised of a polymeric material that is generally highly slippery, such as a fluoropolymer (for example, polytetrafluoroethylene telomer, often called PTFE) or it can be comprised of a polymeric material or other materials that are generally more or less lubricating (for example, having a lower or greater friction coefficient than that of PTFE, respectively). Providing a telomer (eg, PTFE) on the outermost edge of the blade provides a user's skin with contact lubricity. The slippery outer covering layer 49 of Figure 4 and other similar layers described here may have a thickness of about 200 angstroms or more.
    Thus, in the present invention, even while the BAM 44 layer can innately generally provide both rigidity and lubricity properties, increased lubricity may be desired to provide suitable or improved shaving or waxing attributes (e.g., sliding , less tugging and pulling), and as such a slippery material such as PTFE can be added to the edge 40 area on top of the BAM 44 layer. Similarly, if even with the BAM 44 layer, less lubricity is desired to provide suitable or improved shaving or waxing attributes, a non-slip material such as polypropylene can be added to the edge 40 region on the BAM 44 layer. Different blade edge properties may be desirable in a blade unit.
    [0037] As shown in a third alternative embodiment of the present invention in Figure 5, the embodiment of Figure 4 can include a stainless steel substrate 52 and one or more adhesion layers 58 which may comprise niobium, chromium, platinum, titanium or alloys of the above and / or any combination thereof. The adhesion layer 58 can have a thickness of about 200 to about 400 angstroms. The adhesion layer 58 may be desirable to assist in the adhesion of the polymeric layer or PTFE layer 59 to the layer of BAM material 54, which is arranged on the substrate 52 or to provide additional stiffness to the edge region 50.
    [0038] In a fourth alternative embodiment of the present invention shown in Figure 6, the embodiment of Figure 4 is modified showing a cutting edge region of blade 60 with one or more layers of polymeric outer coating 69 arranged over the layer of BAM material 64 and one or more intermediate layers 66 disposed between the BAM layer 64 and the substrate 62. As above, the outer coating layer 69 may desirably be composed of a polymeric material such as a PTFE telomer, while the intermediate layer 66 may desirably be a adhesion layer comprising niobium, chromium, platinum, titanium or alloys of the above and / or any combination thereof. Layer 66 may have a thickness in the range of about 200 to about 400 angstroms. Due to its location, the interlayer 66 can desirably assist in the adhesion of the BAM material 64 to the substrate 62 can provide additional stiffness or hardness for the edge region 60. The outer polymeric coating layer 69 can desirably provide lubricity to the outermost surface that it touches the skin of a user thus providing a more comfortable shave or epilation.
    [0039] The fifth embodiment shown in Figure 7 is a modification of Figure 6 and includes the edge region of blade 70 that is substantially identical to the edge region of blade 60 having a substrate 72, a layer of BAM 74, an intermediate layer 76, and a polymeric outer coating layer 79 with the only difference in Figure 6 being the addition of an adhesion layer 78. The newly added adhesion layer 78 is of the type previously described together with adhesion layer 58 of Figure 5 .
    [0040] The outer coating layer of the polymeric material of the present invention can be partially removed if desired to provide a thinner and more uniform layer using any known methods and for example, the process described in US Patent No. 5,985,459, entitled Method of Treating Razor Blade Cutting Edges, granted on November 16, 1999, attributed to the assignee of the present invention, and incorporated herein in full, by way of reference.
    [0041] Now with reference to Figure 8, yet another embodiment of the present invention the region of edge 80 is shown where at least one layer of BAM 84 is disposed on substrate 82 (as in Figure 2), but in Figure 8, at the at least one outer layer of BAM 85 is additionally disposed over the layer of BAM 84. The outer layer of BAM 85 comprises a composite including the BAM material and at least one other element or compound, the latter being desirably composed of PTFE or other polymeric material. In this way, the outer coating layer BAM 85 has an outer surface 85a which may be more or less slippery than the surface 84a would have been if the outer coating layer 85 had not been disposed thereon.
    [0042] In Figure 9, according to the present invention, a modification of the embodiment of Figure 8 is shown indicating a region of the blade edge 90 having a composite layer of outer coating BAM 95 in which the component materials are combined within the layer in gradient concentration. With an outer covering layer 95 comprising a composite of BAM material and at least one other element or compound desirably comprising PTFE, the gradient is desirably formed so that the PTFE compound of the outer covering layer 95 increases in concentration towards the surface of the BAM layer 94 towards the outer surface 95a of the blade edge. Consequently, the BAM material itself decreases in concentration towards the outer surface of the BAM layer 94 towards the outer surface 95a. Thus, if the BAM 94 layer is not, by itself, lubricious enough, it increases the concentration of PTFE towards surface 95a in the form shown in Figure 9 (inside the outer coating layer BAM 95) could theoretically improve the shaving and waxing attributes resulting in better gliding, less pulling, improved overall comfort as well as fewer cuts and cuts.
    [0043] If desired, the concentration gradient mentioned above can be reversed, so that the outer coating layer BAM 95 would have increasing concentrations of the BAM material in the direction from the outer surface of the BAM layer 94 to the outer surface 95a and the PTFE compound of the outer coating layer BAM 95 decreases in concentration in the direction from the outer surface of the BAM layer 94 to the outer surface 95a.
    [0044] It should be noted that the presence of a concentration gradient as described in Figures 8 and 9 in the present invention is contemplated for the BAM layers as well, with or without the presence of an external BAM coating layer.
    [0045] With the modalities described as having an external coating layer (for example, layers 58 and 78 in Figures 5 and 7), the present invention additionally contemplates that an external coating layer of BAM 95 can be arranged on any layer of outer coating (for example, layers 58 and 78 in Figures 5 and 7) instead of directly arranged on the BAM layer 94.
    [0046] In addition, the outer coating layer of BAM 95 can be a composite composed of a BAM material and various other elements or compounds, instead of or in addition to the PTFE mentioned here offering lubricity benefits for example.
    [0047] It is further contemplated in the present invention that the BAM 94 material layer itself is formed having a concentration gradient.
    [0048] The modalities described here generally described linear blades with end regions and chamfers generally planar or straight. However, the present invention additionally contemplates the BAM material 104 disposed on the upper surfaces 107 of the ends of non-linear blade units (shown as circular) 107a of a substrate (not shown) in a cutting edge region of the blade 100 as shown in Figure 10. BAM material can be deposited using any of the processes described here. It occurs as in any of the alternating modalities shown in Figures 2-9 together with linear blades, they can be similarly extended to the modality in Figure 10. For example, in conjunction with Figures 3 and 6, the end of the non-linear sheet of Figure 10 can first be coated with an intermediate layer (not shown in Figure 10) on which the layer of BAM 104 material is deposited.
    [0049] The non-linear blade edges of the present invention can be of the types described in US Patent No. 4,807,360 entitled Shaving Device, issued February 28, 1989, and / or US Patent No. 4,875,228 entitled Shaving Device , granted on October 24, 1989, both attributed to the assignee of the same, and incorporated herein by reference, in its entirety.
    [0050] The present invention additionally contemplates the BAM material in addition to be deposited on blade edges, being deposited on any other blade components, such as those designated in Figure 1. BAM material coatings, if applied to others cartridge components of the razor and epilator, can theoretically improve resistance to wear and / or slip during shaving or epilation, particularly if arranged in clips or other hair and / or skin management components.
    [0051] Now with reference to Figure 11, an example of a BAM 114 material disposed in cartridge components of the razor or shaver, the two blade retaining clips 11 of Figure 1 are shown according to another embodiment of the present invention. The benefits of gliding and comfort along the way of shaving or waxing can be enhanced by adding the BAM material (e.g. a rigid and lubricious material) to the upper surface 11a of the clips 11 which are generally arranged on the left and right sides of the cartridge. BAM 114 material can be deposited by means of magnetron ion bombardment, as described above, or other feasible methods.
    [0052] With reference to Figure 12, an example of BAM 124 material arranged in dry electric shaving or shaving components, such as on the external and / or internal surfaces of a sheet metal component 120 or appliance cutter elements shaving or dry shaving 122 is shown according to another embodiment of the present invention. An electric or dry razor or epilator usually consists of a set of blades or cutters oscillating or rotating 122, which are held behind a perforated metal sheet 120 that prevents them from coming into contact with the skin and behaves like the second blade in a pair of scissors. When the blade is held against the skin, the hairs pass through the holes 121 in the metal sheet 120 and are cut by the moving cutters 122. Typically there is no lubricant applied in shaving or dry shaving. The addition of BAM coating, for example, on the outer surface of the metal sheet, can improve the slip on the skin. In addition, an advantage of having a BAM coating on the inner surface of a metal sheet (not shown) can generally include reduced friction between the metal sheet and the cutters, which can provide a fresher shave or epilation, longer life extended battery and / or extended metal sheet longevity. A BAM coating 124 disposed on the outer surface of the cutting elements 122 as shown in Figure 12, may also desirably provide improved cutter rigidity and reduced friction.
    [0053] Thus, as described above, with a BAM material being used in blade edges, there is a potential to provide a single coating solution (providing both rigidity and lubricity benefits) to provide improved blade performance and simplified fabrication . In addition, as also described above, the BAM material can be applied to other components of the razor or epilator such as the cartridge and / or components of the razor or dry epilator such as metal sheets and cutting elements and in return provide improved shaving or waxing benefits like wear resistance and lubricity.

Instead, unless otherwise specified, each of these dimensions is intended to mean both the mentioned value and a range of functionally equivalent values around that value. For example, a dimension shown as "40 mm" is intended to mean "about 40 mm".
