Description

Technical Field

[0001] The present disclosure relates generally to displays of razors, and more particularly to displays of lubrication components of razors. Background Art

[0002] Consumers of disposable and system razors (i.e., razor handles with replaceable razor cartridges) continue to demand improved product performance. As a result, razor manufacturers are constantly trying to improve various razor performance attributes that consumers desire. However, even when better razors are designed and manufactured, razor manufacturing companies, advertisers, and retailers face the following difficulties: especially in a meaningful, clear and visual way to convey to consumers that a particular razor product exhibits improved or more effective performance compared to other razor products, such as closeness, less missed hair or comfort, increased glide (i.e., lubricity), moisturization or other benefits.

[0003] Therefore, there is a need for an apparatus and / or method for demonstrating to consumers the specific advantages of using certain razors. There is also a need for a method to demonstrate the performance differences between razors (such as increased lubricity or moisturizing and / or components that release lubricity and / or moisturizing in front of the blade) and clearly communicate these differences to consumers.

[0004] The discussion of shortcomings and needs existing in the art prior to the present disclosure is in no way an admission that one skilled in the art recognized such shortcomings and needs prior to the present disclosure. Summary of the invention

[0005] Various embodiments are directed to a shaving demonstration method that may include providing at least a first razor having a first shaving surface with a first lubricating member. The method may then include exposing the first lubricating member to a composition of water and a fluorescent dye. Next, the method may include engaging at least a first paper with at least the first lubricating member and causing relative movement between the first lubricating member and the first paper. Finally, the method may include exposing the first paper to a light source, which may cause the lubricating pattern to fluoresce to provide a clear visual demonstration of the effectiveness of the first lubricating member in smoothly and continuously applying shaving aids. A single razor may be demonstrated, or multiple razors may be demonstrated simultaneously. For example, according to various embodiments, the method may also include providing a second razor having a second shaving surface with a second lubricating member, and exposing the second lubricating member to the composition. The method may then include engaging the first paper with the second lubricating member and causing relative movement between the second lubricating member and the first paper.

[0006] Other embodiments relate to a shaving demonstration device, which includes a first paper, a liquid composition, a first razor having a first shaving surface with a first lubricating member, and a light source that transmits ultraviolet light to the first paper. The first razor may have: a first position, wherein the first lubricating member deposits the liquid composition onto the first paper; and a second position, wherein the first lubricating member is positioned in a first tank containing the liquid composition. The shaving demonstration device may also include a second razor having a second shaving surface with a second lubricating member. The second razor may have a first position, wherein the second lubricating member deposits the liquid composition onto the first paper. Alternatively, the shaving demonstration device may include a second paper and a second razor having a second shaving surface with a second lubricating member. The second razor may have: a first position, wherein the second lubricating member deposits the liquid composition onto the second paper; and a second position, wherein the second lubricating member is positioned in a second tank. The second razor may also have a second position, wherein the second lubricating member is positioned in the first tank.

[0027] All numerical values ​​herein are assumed to be modified by the term "about", whether or not explicitly stated. The term "about" generally refers to a numerical range that one skilled in the art considers equivalent to the stated value (e.g., having the same function or result). In many cases, the term "about" may include numerical values ​​that are rounded to the nearest significant figure.

[0028] In everyday usage, indefinite articles (such as "a") precede countable nouns, and uncountable nouns almost never take indefinite articles. Thus, it must be noted that, as used in this specification and the claims that follow, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a carrier" includes a plurality of carriers. In particular, when a singular countable noun is listed as an element in a claim, this specification will generally use phrases such as "single." For example, "a single carrier."

[0029] Throughout this specification and the claims that follow, reference will be made to a number of terms that are defined to have the following meanings, unless a contrary intention is apparent.

[0030] As used herein, the term "standard temperature and pressure" generally refers to 25°C and 1 atmosphere. Standard temperature and pressure may also be referred to as "ambient conditions". Unless otherwise indicated, parts are by weight, temperatures are in °C, and pressures are at or near atmospheric pressure. The term "elevated temperature" or "high temperature" generally refers to a temperature of at least 100°C.

[0031] Unless otherwise indicated, all percentages indicating the amount of a component in a composition represent the percentage by weight of the component based on the total weight of the composition. The term "mole percent" generally refers to the percentage of the number of moles of a particular component to the total number of moles in a mixture. The sum of the mole fractions of each component in a solution is equal to 1.

[0032] Where a numerical range is provided, it is understood that each intervening value (to the tenth of the unit of the lower limit unless the context clearly dictates otherwise) between the upper and lower limits of that range, as well as any other stated or intervening value in the stated range, is encompassed within the disclosure. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges, and are also encompassed within the disclosure, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding one or both of those included limits are also encompassed within the disclosure.

[0033] As used herein, the term "mixing" refers to a unit operation in industrial process engineering that involves manipulating a heterogeneous physical system with the goal of making it more homogeneous. Mixing is performed to allow heat and / or mass transfer between one or more streams, components, or phases.

[0034] As used herein, the term "disposed on" refers to a positional state indicating that one object or material is arranged in a position adjacent to that of another object or material. The term does not require or exclude the presence of intermediate objects, materials, or layers.

[0035] Figure 1A 1 is an example according to various embodiments, which shows a perspective front view of a first razor 10. Various embodiments relate to shaving demonstration methods or shaving lubrication demonstrations. These methods may include providing a first razor 10 having a first shaving surface 16 with a first lubricating member 22, such as Figure 1A As shown. The first razor 10 may also include a first handle 12 having a first blade holder unit 14. The first blade holder unit 14 may include a first shaving surface 16 and at least one blade 18 for shaving hair and a first lubricating member 22 positioned behind the at least one blade 18. Figure 1A As shown, the first cartridge unit 14 may further include a supplemental lubrication member 20 positioned in front of at least one blade 18. The supplemental lubrication member 20 is optional, and the first razor 10 need not include the supplemental lubrication member 20. The first lubrication member 22 may have a first leading edge 30 and a first trailing edge 32.

[0036] Figure 1B4 is an example according to various embodiments, which shows a perspective front view of the second razor 40. Some embodiments of the shaving demonstration method can facilitate the comparison of the first razor 10 and the second razor 40. The second razor 40 can be similar in structure to the first razor 10. Therefore, the method can also include providing the second razor 40 having a second shaving surface 46 with a second lubricating member 52, such as Figure 1B As shown. The second razor 40 may also include a second handle 42 having a second blade cartridge unit 44. The second blade cartridge unit 44 may include a second shaving surface 46 and at least one blade 48 for shaving hair, and a second lubricating member 42 positioned behind the at least one blade 48. Although Figure 1B The second razor 40 shown does not include a supplemental lubrication member 20, but it should be understood that the second razor 40 may include a lubrication member 20. Figure 1B The supplemental lubrication member 20 is shown. The second lubrication member 52 may have a second leading edge 60 and a second trailing edge 62 .

[0037] Still refer to Figure 1A and Figure 1B It will be appreciated that blade 18 or blade 48 may be any type of cutting member. For example, blade 18 or blade 48 may comprise a cutting member of an electric razor or trimmer. Variations in the location and number of blades are contemplated. The lubricating member may have any suitable shape. As shown, lubricating members 22, 52 are rectangular strips, but other shapes, such as cylinders or prisms, are also contemplated. Each lubricating member 22, 52 need not be unitary, but may be formed of multiple subunits, such as a series of smaller lubricating members.

[0038] Reference Figure 2A and Figure 2B Various embodiments involve engaging a markable substrate such as paper 26, 56 with a lubricating member 22, 52 of a razor. To ensure good contact between the lubricating member 22, 52 and the paper 26, 56, a contact angle 34, 64 between the lubricating member 22, 52 and the paper 26, 56 may be maintained. Figure 2A and Figure 2B 2 is an example according to various embodiments, which shows a perspective side view of a first razor 10 engaging a first paper 26 at a first contact angle 34 or a second razor 40 engaging a second paper 56 at a second contact angle 64. For example, when the first paper 26 is engaged with the first lubricating member 22, the first lubricating member 22 and the first paper 26 can define a first contact angle 34 having a first leading edge 30 (e.g., Figure 2A as shown) or on the first trailing edge 32 (as shown Figure 2B24). The first contact angle 34 may be in the range of about 0 to about 5 degrees, or about 0.5 to about 4.5 degrees, or about 1 to about 4 degrees, or about 2 to about 3 degrees. Similarly, when the first paper 26 or the second paper 56 is engaged with the second lubricating member 52 after exposing the second lubricating member 52 to the composition 24, the second lubricating member 52 and the first paper 26 or the second paper 56 may define a second contact angle 64 having a second vertex 66 on the second leading edge 60 or on the second trailing edge 62. The second contact angle 64 may be in the range of about 0 to about 5 degrees, or about 0.5 to about 4.5 degrees, or about 1 to about 4 degrees, or about 2 to about 3 degrees.

[0039] like Figure 2A As shown, the paper 26, 56 can be placed on a support structure 80 having a top surface 87 on which the paper rests. An optional spacer 89 can be placed on the top surface 87 to help ensure the desired contact angle 34, 64. The spacer 89 can be permanent or removable. For example, the spacer 89 can be a rectangular plastic piece about 1 inch (about 25.4 mm) wide by about 2 inches (about 50.8 mm) long and about 0.25 inches (about 6.35 mm) high, which can be placed or bonded to the surface 87 of the support structure 80. The paper 26, 56 and subsequently the razor 10, 40 can rest on the spacer 89 to ensure complete and even surface contact across the length of the lubrication member 22, 52. Although only Figure 2A 8, 56. The top surface 87 or any spacers 89 disposed thereon may have a coefficient of friction suitable for allowing the paper 26, 56 to slide without excessive resistance. The top surface 87 or any spacers 89 disposed thereon may include any suitable material, such as a plastic material or a metal. ® The relative movement should be such that the height of the paper 26, 56 relative to the top surface 87 remains substantially constant throughout the display, thereby ensuring that the contact angle between the razor 10, 40 and the paper 26, 56 does not change, which could result in less than the entire surface of the lubricating member 26, 56 engaging the paper 26.

[0040] It should be understood that some shaving cartridges 14, 44 may have a rounded or curved profile. In such cases, it may not be possible to test any supplemental lubrication member 20 simultaneously with the primary lubrication member 22, 52 due to the manner in which the shaving cartridge 14, 44 may contact the surface. Therefore, the method may include selecting a contact angle 34, 64 that provides good contact with a particular lubrication member 22, 52, such as the primary lubrication member 22, 52 as opposed to any supplemental lubrication member 20. It may be beneficial to select the lubrication member 22, 52 that releases the most shaving aid.

[0041] A method of displaying a first razor 10 or comparing the first razor 10 to one or more other razors, such as a second razor 40, may provide a visual display of the effectiveness of the lubrication member 20, 22, 52 of each razor. The lubrication member 20, 22, 52 may deliver a shaving aid to the user's skin. The shaving aid may provide one or more skin benefits to the consumer, such as moisturizing, reducing irritation during shaving, cooling, warming, anti-acne, or sun protection. According to various embodiments, the shaving aid from the replenishing lubrication member 20 may be coated or deposited onto the skin and onto at least one blade 18, 48 during a shaving stroke. The shaving aid from the first lubrication member 22 or the second lubrication member 52 may be primarily delivered or deposited onto the skin at the end of a shaving stroke, but may also deposit shaving aid onto at least one blade 18, 48 during subsequent or overlapping shaving strokes. The shaving aid of any of the lubrication members 20, 22, 52 may be the same or different. According to various embodiments, any or all of the lubricating members 20, 22, 52 may be molded or extruded lubricating components, gel reservoirs, and / or shaving aid dispensing members. Various methods may provide a visual display of how the lubricating members 20, 22, 52 of the razor 10, 40 deposit a liquid composition onto a surface, such as paper 26, 56, which may be similar to how the razor 10, 40 deposits shaving aid onto the surface of a user's skin.

[0042] In addition to providing a first razor 10 having a first shaving surface 16 with a first lubricating member 22, the shaving demonstration method according to various embodiments may further include exposing the first lubricating member 22 to a composition 24 comprising water and an indicator composition. The composition 24 may be prepared by mixing its components. The composition 24 may include water in an amount of about 95% by weight to about 99% by weight, or about 96% by weight to about 98% by weight. The remainder of the composition 24 may include an indicator composition.

[0043] Typically, the indicator composition of composition 24 should be water-soluble. The indicator composition of composition 24 may include a fluorescent dye, or more specifically an ultraviolet fluorescent dye. Fluorescent dyes show fluorescence. As used herein, "fluorescence" is the emission of light by a substance that has absorbed light or other electromagnetic radiation. For example, a fluorescent dye can absorb light of a specific color and emit light of a different color, usually with a longer wavelength. When exposed to ultraviolet radiation, the ultraviolet fluorescent dye becomes fluorescent, emitting visible light. The indicator composition of composition 24 may include pyranine, such as a pyrene dye, such as solvent green 7, which is commonly used in yellow highlighters. Pyranine is a hydrophilic, pH-sensitive fluorescent dye that comes from a group of chemicals known as aryl sulfonates. The indicator composition of composition 24 may include triarylmethane dyes. For example, the indicator composition of composition 24 may include triphenylmethane dyes, such as acid blue 9, which is commonly used in blue highlighters. Triphenylmethane dyes include any member of a group of synthetic organic water-soluble dyes having a molecular structure based on the hydrocarbon triphenylmethane. Another example of triarylmethane dyes is rhodamine dyes. The indicator may include rhodamine dyes, such as solvent red 49, which is commonly used in pink highlighters. Rhodamine refers to a family of related dyes, i.e., a subset of triarylmethane dyes. Rhodamine may be a derivative of xanthene. The indicator composition of composition 24 may include xanthene dyes, such as Basonyl red 485. Xanthene dyes refer to all dyes containing xanthene nuclei, including fluorescein, eosin, and rhodamine. Xanthene dyes are often fluorescent, yellow to pink to blue-red bright color dyes. The indicator composition of composition 24 may include coumarin dyes, such as basic yellow 40. Coumarin dyes include any water-soluble dyes with a molecular structure based on coumarin. A combination of Basonyl red 485 and basic yellow 40 is often used in orange highlighter markers. The specific examples given are not intended to be limiting. Any suitable indicator composition may be used in composition 24. The indicator composition of composition 24 may include any combination of the above examples as well as any other suitable dye or indicator. The indicator composition of composition 24 need not always be fluorescent or include a fluorescent compound. For example, the indicator composition of composition 24 may include food coloring or other compounds as long as it helps to visualize the liquid deposited therefrom. It should be understood that different compositions 24 may be used to distinguish each razor shown. For example, Fig. 7A As shown, a first composition 24a and a second composition 24b can be used. The first composition 24a can have a different composition than the second composition 24b. For example, a unique dye having a different color for each razor 10, 40 can be used to easily distinguish between different cartridges.

[0044] Reference FIG. 3A to FIG. 3D, methods according to various embodiments may include exposing the first lubricating member 22 to the composition 24 and then contacting the first paper 26 with the first lubricating member 22 (at FIG. 3A to FIG. 3D After engaging the first paper 26 with the first lubricating member 22, the method may include causing relative movement between the first lubricating member 22 and the first paper 26. Finally, the method may include exposing the first paper 26 to a light source 28. It should be understood that the step of exposing the first paper 26 to the light source 28 may be performed during or after causing relative movement between the first lubricating member 22 and the first paper 26. The light source 28 may substantially emit light 29 having a wavelength in the ultraviolet spectrum range, for example, from about 100 nm to about 400 nm, or more specifically in the range of about 320 nm to about 400 nm.

[0045] Still refer to Figure 3B , the first lubricating member 22 of the first razor 10 can deposit a liquid of a composition 24 including water and an indicator composition on the first paper 26 in a first lubricating pattern 100. Since the water causes the shaving aid to leach out of the lubricating member 22, 52, the deposited liquid can include not only the composition 24 but also the shaving aid. The first lubricating pattern 100 can fluoresce in response to exposure to light 29 from the light source 28. As used herein, "fluoresce" means to glow or emit light brightly due to fluorescence. As discussed, the light 29 can be ultraviolet light. According to various embodiments, it may be beneficial to reduce or eliminate other lights, such as by performing the demonstration method in a dark room except for the light 29.

[0046] The step of causing relative movement between the first lubricating member 22 and the first paper 26 after the first paper 26 is engaged with the first lubricating member 22 of the first razor 10 is shown in FIG. Figure 3B The relative motion may be caused by moving the first paper 26, the first razor 10, or both. The motion may be along an approximately linear path in an approximately single direction. For example, Figure 3B As shown, the first paper 26 can be rolled from the first feed roller 76 across the paper support structure 80 and along the longitudinal direction MD to the first receiving roller 78. The first receiving roller 78 can be wound around an axis, for example, by a conveying mechanism. The conveying mechanism can be, for example, Figure 3A The hand crank 79a shown or Figure 3B Motor 79b is shown. It should be understood that the take-up roller 78 is optional. The paper 26 may alternatively be pulled by hand without wrapping around the take-up roller 78. In either case, the relative movement between the first lubrication member 22 and the first paper 26 should occur stably and at a predetermined rate.

[0047] For embodiments in which multiple razors 10, 40 are displayed, the speed of the relative movement between the razors 10, 40 and the paper 26, 56 to which they are engaged should be approximately the same to ensure uniform distribution of the composition 24 across the paper 26, 56. The rate can be selected to ensure that the display provides the observer with enough time to understand the differences between the tested razors 10, 40 and / or to understand the quality of the lubrication pattern deposited by a given razor 10, 40. If the relative movement is too fast, the paper 26, 56 may not show a uniform distribution of the composition 24. On the other hand, if the relative movement is too slow, the composition 24 has more time to be absorbed into the paper 26, 56 and may cause tearing. According to various embodiments, the relative movement between the first lubricating member 22 and the first paper 26 can occur at a rate of about 1 inch (about 25.4 mm) / second to about 5 inches (about 127 mm) / second, or about 2 inches (about 50.8 mm) / second to about 4 inches (about 101.6 mm) / second. For example, the first sheet 26 may be wrapped around the first receiving roller 78 or otherwise pulled through the support structure 80 in the machine direction MD at this rate.

[0048] A single razor 10 may be shown, or a plurality of razors 10, 40 may be shown simultaneously. For example, according to various embodiments, the method may further include providing a second lubricating member 52 to a second razor 40 having a second shaving surface 46; exposing the second lubricating member 52 to the composition 24; engaging the first paper 26 with the second lubricating member 52 after exposing the second lubricating member 52 to the composition 24; and causing relative movement between the second lubricating member 52 and the first paper 26 after engaging the first paper 26 with the second lubricating member 52. The step of exposing the second lubricating member 52 to the composition 24 is shown in Figure 3A The steps of causing relative movement between the second lubricating member 52 and the first paper 26 are shown in Figure 3B Like the first lubricating member 22 of the first razor 10, the second lubricating member 52 of the second razor 40 can deposit a liquid of the composition 24 comprising water and the indicator composition on the first paper 26 in a second lubricating pattern 102. The second lubricating pattern 102 can fluoresce in response to exposure to light 29 from the light source 28. The relative movement between the second lubricating member 52 and the first paper 26 can occur at the same rate as the relative movement between the first lubricating member 22 and the first paper 26.

[0049] Any number of razors 10, 40 and any number of papers 26, 56 may be used simultaneously. The relative motion between the razors 10, 40 and their respective papers 26, 56 may be the same or different. FIG. 3C to FIG. 3DAn embodiment employing multiple sheets 26, 56 is shown. As shown, the method may include providing a second razor 40 having a second shaving surface 46 with a second lubricating member 52; exposing the second lubricating member 52 to the composition 24; engaging the second sheet 56 with the second lubricating member 52 after exposing the second lubricating member 52 to the composition 24; causing relative movement between the second lubricating member 52 and the second sheet 56 after engaging the second sheet 56 with the second lubricating member 52; and exposing the second sheet 56 to the light source 28. As in other embodiments, the second lubricating pattern 102 may fluoresce in response to exposure to light 29 from the light source 28. The relative movement between the second lubricating member 52 and the second sheet 56 may occur at a rate of about 1 inch (about 25.4 mm) / second to about 5 inches (about 127 mm) / second, or about 2 inches (about 50.8 mm) / second to about 4 inches (about 101.6 mm) / second.

[0050] According to various embodiments, exposing the first lubricating member 22 and / or the second lubricating member 52 to the composition 24 may include immersing the first lubricating member 22 and / or the second lubricating member 52 in the composition 24. The composition 24 may be stored in one or more tanks 72, 74. For example, both the first lubricating member 22 and the second lubricating member 52 may be immersed in the first tank 72 containing the composition 24. Alternatively, the first lubricating member 22 may be immersed in the first tank 72 containing the first part of the composition 24, and the second lubricating member 52 may be immersed in the second tank 74 containing the second part of the composition 24. The lubricating members 22, 52 may be immersed in the composition 24 for a certain time interval. The time interval may be the same or different for each lubricating member 22, 52. The time interval may be from about 1 minute to about 3 minutes, or from 90 seconds to about 2 minutes. The time interval may represent a typical consumer shaving habit of running the razor 10, 40 under a faucet or shower head before performing the first shaving stroke. If the time interval is too long, the lubricant from the lubricating member 22, 52 may leach into the water and change the state of the lubricating member 22, 52, which may not provide a good display of the lubricating member 22, 52 under a normal use environment. It should be understood that several time intervals can be tried before finding the optimal time interval. According to various embodiments, the method may include dipping the first lubricating member 22 and / or the second lubricating member 52 into the composition 24 multiple times. Multiple immersions of the lubricating member 22, 52 may allow each lubricating member 22, 52 to have more time to absorb the composition 24 to which it is exposed. The absorption of the composition 24 by the lubricating member 22, 52 may be performed as a concentration gradient, wherein the composition 24 moves from the outer surface or layer of the lubricating member 22, 52 toward the inner core or layer over time. Continuously exposing only the outermost surface or layer of the lubricating member 22, 52 may cause the surface or layer to be excessively degraded. A series of immersions may make the composition 24 more evenly distributed in the lubricating member 22, 52. According to various embodiments, the method may include immersing the lubricating member 22, 52 in the composition 24 for a first time interval, removing the lubricating member 22, 52 from the composition 24 for a second time interval, and immersing the lubricating member 22, 52 in the composition 24 for a third time interval. The first time interval, the second time interval, and the third time interval may each be about 1 minute to about 3 minutes, or 90 seconds to about 2 minutes. According to various embodiments, the third time interval may be less than the first time interval.

[0051] The method according to various embodiments can be repeated multiple times using the same razor 10 or multiple razors 10, 40, so that the step of providing the razor 10, 40 can be omitted in subsequent presentations. When the razor 10 or razors 10, 40 are repeatedly used, the step of exposing the lubricating member 22, 52 to the composition 24 can be performed for a time interval of about 10 seconds to about 60 seconds, or 20 seconds to about 50 seconds, or about 30 to about 40 seconds.

[0052] According to various embodiments, the method may include dulling, moving or removing one or more blades 18, 48 from the first razor 10 and / or the second razor 40. This step may ensure that the blades 18, 48 engage the paper 26, 56, which engagement may result in cutting the paper and / or distorting the lubrication pattern 100, 102.

[0053] The first paper 26 and / or the second paper 56 may be thermal paper. Thermal paper is a paper that is typically coated with a material that is formulated to change color when exposed to heat. It is used in thermal printers, particularly in inexpensive or lightweight devices, such as adding machines, cash registers, and credit card terminals for printing receipts. Thermal paper is advantageous because it does not absorb water as quickly as uncoated paper, thereby providing improved spreading of the composition 24 along the paper 26, 56 to produce a clear lubricating pattern 100, 102. Any suitable paper may be used. The paper 26, 56 must be able to absorb at least some of the composition, but like thermal paper, may have one or more coatings applied thereto. A completely water-impermeable coating (such as a plastic sheet) will also not show the distribution of the composition 24 from the lubricating member 22, 52.

[0054] Figure 4 FIG. 1 is an example of an enlarged perspective side view of a razor display apparatus 70 and method 700 in a first configuration according to various embodiments. The apparatus 70 may also include a support structure 80 on which the paper 26, 56 may be disposed. The support structure 80 may include a first side wall 82 and a second side wall 84, such as Figure 4 As shown. The first side wall 82 and the second side wall 84 may support a crossbar 86. The crossbar 86 may be permanently or removably mounted. The crossbar 86 may be adjustable so that it can be tightened or loosened, for example, via a hexagonal pin or a screw. When the crossbar 86 is tightened, it may be substantially fixed so that it does not rotate. The first arm 88 may be pivotally mounted on the crossbar 86 via a first pivot 90. The first pivot 90 may be adjustable so that it can be tightened or loosened, for example, via a hexagonal pin or a screw. When the first pivot 90 is tightened, it may be substantially fixed so that it does not rotate around the crossbar 86. The first arm 88 may include a first adjustable razor grip 92 for gripping the first razor 10 by the first handle 12. The second arm 94 may be pivotally mounted on the crossbar 86 via a second pivot 96. The second pivot 96 may be adjustable so that it can be tightened or loosened, for example, via a hexagonal pin or a screw. When the second pivot 96 is tightened, it can be substantially fixed so that it does not rotate about the crossbar 86. The second arm 94 can include a second adjustable razor grip 98 for gripping the second razor 40 by the second handle 42.

[0055] Figure 5 and Figure 61 shows results that can be exhibited by methods according to various embodiments. The first lubricating pattern 100 deposited by the first lubricating member 22 of the first razor 10 is smooth and consistent, uniformly fluorescing under the light 29 from the light source 28. On the other hand, the second lubricating pattern 102 deposited by the second lubricating member 52 of the second razor 40 is not smooth and consistent, but has a plurality of spots 102a (e.g., Figure 5 ) and / or stripes 102b (as shown Figure 6 ). Spots 102a and stripes 102b are portions of the second paper 56 where the composition 24 is not applied due to poor performance of the second lubricating member 52. Thus, the method can provide a clear, visible demonstration of how different lubricating members 22, 52 will effectively deliver liquid to the user's skin, which can be similar to how different lubricating members 22, 52 will effectively deliver shaving aid to the user's skin. The demonstration illustrates that some lubricating members 22, 52 may not deposit a smooth, consistent layer of shaving aid to provide one or more skin benefits to the consumer, such as moisturizing, reducing irritation during shaving, cooling, heating, anti-acne, or sun protection. Such differences between the razors 10, 40 may not be visible or may only be poorly visible when the razors 10, 40 are used to shave hair.

[0056] Various embodiments may also include quantifying the area of ​​each lubricating pattern 100, 102 that is not smoothly and uniformly covered by the composition 24. For example, the total area of ​​each lubricating pattern 100, 102 can be compared with the total area occupied by the spots 102a and / or stripes 102b. Such quantification can provide a degree of coverage, which can be specified as a percentage. For example, the first lubricating pattern 100 may have a first degree of coverage of about 90% to about 100%, which means that the composition 24 covers about 90% to about 100% of the total area passed by the first lubricating member 22 during the test. On the other hand, the second lubricating pattern 102 may have a second degree of coverage of about 50% to about 90%, which means that the composition 24 only covers about 50% to about 90% of the total area passed by the second lubricating member 52. Fig. 7A , 7B 7C are examples showing a perspective side view of a razor display device 70, according to various embodiments.

[0057] Fig. 7A , 7B 7C are perspective side views showing a razor display device 70 in a first configuration, a second configuration, and a third configuration, respectively, according to examples of various embodiments. Fig. 7A, the first razor 10 is shown fully flipped into position P7 so that it is rotated as far away from the first canister 72 as possible. Similarly, the second razor 40 is shown fully flipped into position P8 so that it is rotated as far away from the second canister 74 as possible. The first paper 26 and the second paper 56 are shown in a relaxed state. These positions can be advantageous in allowing easier access to the canisters 72, 74. Figure 7B , the first razor 10 is shown in its second position P2, wherein it is rotated into the first can 72. The second razor 40 is shown in its second position P4, wherein it is rotated into the second can 74. Finally, in Figure 7C , the first razor 10 is shown in its first position P1, engaging the first paper 26. The second razor 40 is shown in its first position P5, engaging the second paper 56. Likewise, the first paper 26 and the second paper 56 are shown in a relaxed state. When the papers 26 and 56 are pulled to cause relative movement between the razors 10, 40 in the machine direction MD, the papers 26, 56 may first be raised at an angle 106 and pulled along a path 104 that is substantially aligned with the positions of the first razor 10 and the second razor 40. As previously described, according to various embodiments and when testing various razors 10, 40, it is beneficial to ensure that the height of the papers 26, 56 relative to the top surface 87 of the support 80 remains substantially constant throughout the display process to ensure that the contact angle between the razors 10, 40 and the papers 26, 56 does not change, which may result in less than the entire surface of the lubrication member 22, 52 engaging the paper 26, 56.

[0058] Figure 8700 is an example according to various embodiments, which shows a process flow chart of a razor demonstration method or a shaving lubrication demonstration method 700.

[0062] The following examples are presented to provide those of ordinary skill in the art with a complete disclosure and description of how to implement the methods, how to prepare and how to use the compositions and compounds disclosed and claimed herein. Efforts have been made to ensure accuracy with respect to numbers (e.g., amounts, temperatures, etc.), but some errors and deviations should be considered. The purpose of the following examples is not to limit the scope of the various embodiments, but rather to provide examples that illustrate specific embodiments only.

[0063] Resources used

[0064] Use the following items: YELLOW SHARPIE ® Highlighter, 32oz plastic beaker, multiple 3" thermal paper rolls, hex wrench set, toothpicks or small files, a pair of needle nose pliers, two 21" black lights, measuring tape, a pair of scissors, permanent markers, and one or more razors.

[0065] Step 1: Prepare the Blade Holder

[0066] For some razors, no adjustment is required. For other razors, only the metal side clips need to be removed from each cartridge using needle nose pliers and then the blades are removed. For still other razors, the blades are not removed because the blades are molded into the cartridge and cannot be removed. In order to keep the product variability the same for all products, a toothpick or file may be used to dull the blades from one end to the other to ensure that they do not touch the paper during display.

[0067] Step 2: Prepare the shaving demonstration equipment

[0068] The hex wrench can be used to loosen any element of the shaving display apparatus that needs adjustment. For example, it may be necessary to loosen any side clamps that hold the crossbar to the support structure. Insert the metal mandrel into the holes on the 2 thermal paper rollers. Place the 2 thermal paper rollers inside the apparatus and align with the holes for the metal rod. Insert the metal rod through the two thermal paper rollers, replace the metal clamps, and tighten with the hex wrench.

[0069] After installing the 2 thermal paper rollers, use the hex wrench to attach the test product to the 2 pivot arms located on the top of the unit. Do not tighten. Once the test product is attached to the pivot arms, place them face down on the square Plexiglas strip on the test surface. For best surface contact, adjust the handle until the blade holder lies flat and centered on the square Plexiglas strip. After adjusting for best surface contact, use the hex wrench and pliers to tighten the hex bolts attaching the test product. Make sure the handle is now locked in place and does not move.

[0070] Prior to testing, place the shaving demonstration apparatus on a flat surface and aim one black light above and perpendicular to the system. A second black light was aimed above the path where the paper would be pulled for best visibility.

[0071] Step 3: Prepare UV solution

[0072] Fill a 32oz beaker with room temperature (warm) water. Use tongs to remove 3 yellow SHARPIE ® Remove the end cap from the highlighter and drop the cotton insert into the water. Allow the insert to soak for approximately 10 minutes. Before removing, squeeze each cotton insert by hand to remove any remaining liquid. After removing the cotton insert, divide the UV solution into 2 separate 8oz containers.

[0073] Step 4: Testing

[0074] Begin by unrolling the thermal paper on top of the support structure, which may include a plexiglass surface for the test razor to rest on. Extend the paper past the front of the support structure. Optionally attach the paper to a receiving roller. Next, place a container containing the UV solution on the top back side of the support structure and on top of the thermal paper. Turn the test razors over and immerse them in the solution, not allowing the lubricating member to contact the surface / side of the container. Soak the test razors for approximately 3 minutes. A 3 minute soak is required only for the first run, all subsequent runs require a 10 second soak before repeating. After the required soaking time is complete, carefully lift the test razors and remove the UV solution container. Carefully rotate the test razors to their starting position with the blade holder facing down on the thermal paper. Make sure the black light is on and the white light is off. Carefully grasp the ends of the two pieces of thermal paper and slowly pull the thermal paper through the system at a steady and consistent rate.

[0075] Once the saturated lubrication member stops dispensing UV visible ink, stop pulling the thermal paper roller. Use scissors to cut the paper after the last indication of visible UV ink. Place the paper on a flat surface and measure the length of visible UV ink left on the paper. First measure where the razor starts on the paper and stops where there is a visible break in the lubrication distribution. Record the data. Repeat the above steps for a minimum of 10 runs per product. If the first two pulls are interrupted at 10 inches to 15 inches (about 254mm to about 381mm), check the blade holder to ensure optimal surface contact. Short breaks may indicate the need for adjustment.

[0076] The dimensions and values ​​disclosed herein should not be understood as being strictly limited to the exact numerical values ​​cited. Instead, unless otherwise indicated, each such dimension is intended to represent the stated value and a functionally equivalent range around that value. For example, a dimension disclosed as "40 mm" is intended to mean "about 40 mm".
