## Background
FIELD OF THE INVENTION
The present invention relates to demonstration apparatuses and methods for illustrating different benefits of razors in general, and more particularly, to apparatuses and methods for illustrating lubrication and/or moisturization performance and/or other performance differences of shaving razors.
BACKGROUND OF THE INVENTION
Consumers of disposable and system shaving razors (i.e., razor handles having a replaceable razor cartridge) continue to demand improved product performance. As a result, razor manufacturers continually try to improve upon various shaving razor performance attributes that are desired by consumers. However, even when a better shaving razor is designed and manufactured, razor manufacturing companies, advertisers and retailers face difficulty in communicating to the consumers, especially in a meaningful, clear and visual manner, that a particular shaving razor product demonstrates improved or more effective performance, for example closeness, fewer missed hairs or comfort, increased glide (i.e., lubrication), moisturization, or other benefits compared to other shaving razor products.
Accordingly, there is a need for an apparatus and/or a method for demonstrating to consumers particular advantages of using certain shaving razors. There is also a need for a method to demonstrate performance differences between shaving razors (such as increased lubrication or moisturization and/or components that release lubrication and/or moisturization in front of the blades) and to clearly communicate these differences to consumers.
SUMMARY OF THE INVENTION
In one aspect, the invention features, in general, a simple, efficient shaving demonstration method for communicating to a consumer particular advantages of using a certain shaving razor. The shaving demonstration method may include providing a first shaving razor having a shaving surface with at least one blade having a cutting edge. A transparent first surface may be provided and may be contacted by the shaving surface of the first shaving razor. The shaving demonstration method may include a step of illustrating the shaving surface of the first shaving razor against the transparent first surface through a transparent second surface opposite the first surface. In addition, a step of moving the razor along the transparent first surface may be included to illustrate a consumer benefit.
If, desired, particular embodiments may optionally include releasing a first substance from a first component of the first shaving razor in front of the at least one blade and onto the transparent first surface. The shaving demonstration method may optionally include the first substance covering the at least one blade.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1A and 1B, perspective views of a first shaving razor 10 and a second shaving razor 30 are shown, respectively. The first shaving razor 10 may include a handle 12 having a blade cartridge unit 14. The blade cartridge unit 14 may be mounted to an end of the handle 12. The blade cartridge unit 14 may have a shaving surface 16 with at least one blade 18 for shaving hair and a first lubricating component 20 positioned in front of the at least one blade 18 for delivering a liquid to the skin. For example, the liquid may cover or be deposited onto the at least one blade 18 during a shaving stroke. The shaving surface 16 of the first shaving razor 10 may also have a second component 22 positioned behind the at least one blade 18 for delivering a liquid to the skin. The structure of the first component 20 and the second component 22 may be the same or different. In certain embodiments, the first lubricating component 20 and/or the second lubricating component 22 may be a molded or extruded lubricating bar, a gel reservoir and/or liquid dispensing member. The liquid may provide consumers one or more skin benefits such as moisturization, less irritation during shaving, cooling, heat, anti-acne, or sun protection. The liquid of the first component 20 and the liquid of the second component 22 may be the same or different. It is understood that blade 18 may be any type of cutting member. For example, the blade 18 may include a cutting member of an electric razor or trimmer
The second shaving razor 30 may include a handle 32 having a blade cartridge unit 34. The blade cartridge unit 34 may be mounted to an end of the handle 32. The blade cartridge unit 34 may have a shaving surface 36 with at least one blade 38 for shaving hair and a first lubricating component 40 positioned in behind the at least one blade 38 for delivering a substance (e.g., liquid) to the skin. The structure of the first component 20 of the first shaving razor 10 and the first component 40 of the second shaving razor 30 may be the same or different. In certain embodiments, the first lubricating component 40 may be a molded or extruded lubricating bar, a gel reservoir and/or liquid dispensing member. The substance delivered by the first component 20 of the first shaving razor 10 and the substance delivered by the first lubricating component 40 of the second shaving razor 30 may be the same or different.
Referring to FIGS. 2A and 2B, perspective rear views of the first shaving razor 10 and the second shaving razor 30 are shown. The first shaving razor 10 may contact a transparent first surface 42a and the second shaving razor 30 may contact a transparent first surface 42b. It is understood that the transparent shaving surfaces 42a and 42b may be illustrated as separate surfaces or the same surface depending on the particular demonstration method. For example, the transparent shaving surfaces 42a and 42b may be the same surface for a side by side comparison of the first shaving razor 10 and the second shaving razor 30. The transparent first surfaces 42a, 42b represent a surface of the skin to be shaved (i.e., a demonstration surface). The transparent first surfaces 42a, 42b may comprise glass, plastic or any other transparent material. The transparent first surfaces 42a, 42b may also be tinted. In certain embodiments, the transparent first surfaces 42a, 42b may comprise a grid 44a, 44b. The grid 44a, 44b may allow a consumer to better follow movements of the first and second shaving razors 10 and 30 against the transparent first surface 42. The grid 44a, 44b is illustrated as squares, but any geometry may be used for the grid to illustrate a surface and the relative position in space of the first and second shaving razors 10 and 30. It is also understood that all or a portion of the demonstration method may be digitally created or animated. For example, the grid 44a, 44b may be part of a plane of glass or may be digitally created. The transparent first surfaces 42a, 42b may optionally include hairs to mimic the surface of skin. The hairs may be physically attached to the transparent first surface 42a, 42b or digitally added to the transparent first surface 42a, 42b. 
Typical shaving demonstrations are not able to illustrate shaving surfaces of razors during a shaving stroke because skin (natural or artificial) is not transparent. The consumer is able to see a before image (e.g., hair on the skin) and after image (hair removed from skin), but not an image during a shaving stroke. For example, such shaving demonstrations may illustrate a man shaving, but the shaving surface of the razor is pressed against the skin, thus hiding the blades and other components. As shown in FIGS. 2A and 2B, the shaving surfaces 16 and 36 are hidden from view. Accordingly, previous demonstration methods could only demonstrate components (such as lubrication bars or gel reservoirs) that release substances onto the skin behind one of the blades, but not in front of the blades. Accordingly, the consumer may not have a clear understanding of the various components of the shaving razor, how they work, or the benefits they provide.
Referring to FIGS. 3A and 3B perspective side views of the first shaving razor 10 and the second shaving razor 30 are illustrated against the transparent first surfaces 42a,42b, respectively. The first shaving razor 10 and the second shaving razor 30 are illustrated rotating along with the transparent first surface 42a,42b to guide the consumer from the rear view of first shaving razor 10 and the second shaving razor 30 shown in FIGS. 2A and 2B towards a left side view of the first shaving razor 10 and the second shaving razor 30 in FIGS. 3A and 3B. As shown in FIGS. 3A and 3B, the shaving surface 16 and 36 are still hidden from view. The first shaving razor 10 and the second shaving razor 30 may continue to rotate along with the respective transparent first surface 42a,42b, as shown in FIG. 4A and 4B. FIGS. 4A and 4B are perspective front-side views of the first shaving razor 10 and the second shaving razor 30 against the respective transparent first surface 42a,42b. In FIGS. 4A and 4B the shaving surface 16 of the first shaving razor 10 and the shaving surface 36 of the second shaving razor 30 are visible from viewing through a second transparent surface 46a,46b that is opposite the respective transparent first surface 42a,42b (e.g., 180 degrees). The transparent first surface 42a,42b and the transparent second surface 46a,46b allow the shaving surface 16 of the first shaving razor 10 and the shaving surface 36 of the second shaving razor 30 to be seen by a consumer. For example, in FIGS. 4A and 4B, the at least one blade 18 of the first shaving razor 10 and the at least one blade 38 of the second shaving razor 30 become visible. The first and second components 20 and 22 of the first shaving razor 10 and the first component 40 of the second shaving razor 30 also become visible in FIGS. 4A and 4B. The rotation may continue until the entire shaving surface of the first shaving razor and the entire shaving surface of the second shaving razor become visible, as illustrated in FIGS. 5A and 5B.
FIGS. 5A and 5B illustrate the first shaving razor 10 and the second shaving razor 30 (respectively) continuing to rotate along with the transparent first surface 42a,42b until a front view of the first shaving razor 10 and the second shaving razor 30 against the transparent first surface 40 are shown through the respective transparent second surface 46a,46b. In certain embodiments, the first shaving razor 10 and the second shaving razor 30 along with the respective transparent first surface 42a,42b may be illustrated as rotating a total of about 20 degrees to about 200 degrees. For example, FIGS. 2A and 2B may illustrate the first and second shaving razors 10 and 30 rotated to an initial 15-40 degree rotated view, FIGS. 3A and 3B may be rotated an additional 40-70 degrees, FIGS. 4A and 4B may be rotated an additional 20-40 degrees, and FIGS. 5A and 5B may be rotated an additional 50-70 degrees.
In FIGS. 5A and 5B the first shaving razor 10 and the second shaving razor 30 are shown in a first position against the transparent first surface 42a,42b. The grid 44a,44b may facilitate illustrating the position of the first and second shaving razors 10, 30 against the respective transparent first surface 42a,42b. As shown in FIGS. 6A and 6B, the first shaving razor and/or the second shaving razor 10, 30 may move relative to the transparent first surface 42a,42b to illustrate a consumer benefit, such as lubrication or moisturization. As the first shaving razor 10 move relative to the transparent first surface 42a (e.g., slide down in the direction of the arrows of FIG. 5A), the first component 20 of the first shaving razor 10 may release a first substance 50 against the transparent first surface 42a and the second component 22 of the first shaving razor 10 may release a second 52 substance against the transparent first surface 42a. Similarly, the first component 40 of the second shaving razor 30 may release a substance 54 against the transparent first surface 42b. Accordingly, the first component 20 of the first shaving razor 10, the second component 22 of the first shaving razor 10 and the first component 40 of the second shaving razor 30 are illustrated as releasing respective substances 50, 52 and 54 against the respective transparent first surface 42a,42b as viewed through the second transparent surface 46a,46b (respectively). In certain embodiments, the first substance 50 released by the first component 20 of the first shaving razor 10 may be deposited (e.g., cover) the at least one blade 18. The deposit of the first substance 50 such as a lubricant or moisturizer (e.g., an oil or Polyox) onto the at least one blade 18 may help reduce shaving irritation caused by nicks and cuts or provide other benefits. The substances 50, 52 and 54 may be the same or different and may have similar or different benefits. In certain embodiments, the substances 50 and 52 (and/or the components 20 and 22) may be represented by the same color or different colors. For example the substance 50 may be yellow and the substance 52 may be blue. Accordingly, the color behind the second component 22 may be green (e.g., the resulting combinations of the color of the substances 50 and 52).
It is understood that the first component 20 and/or the second component 22 of the first shaving razor 10, as well as any substances released may be generated digitally (e.g., using animation). A non-limiting example may include a shaving demonstration method with a substance released by the first and second components 20 and 22 of the first shaving razor 10 are images of a liquid or a path of liquid. Digital animation may allow special effects to be added such adding additional light or sparkles to any substances released. In certain embodiments, the first shaving razor 10 and the second shaving razor 30 may be black and white, but the first component 20 and the second component 22 of the first shaving razor 10 and the first component of the second shaving razor may be colored to further emphasize a benefit to consumers. For example, the first component, the second component may be shown in the color blue. The at least one blade may also be shown as blue to illustrate the substance deposited on the at least one blade 18.
Referring to FIG. 7, a schematic representation of a possible example of a shaving demonstration method 100 is illustrated. The shaving demonstration method may comprise a first step 110 of providing a first shaving razor having a shaving surface with at least one blade, such as the first shaving razor 10 with shaving surface 16, as previously described. In a second step 112, a transparent first surface may be provided, such as the transparent first surface 42a previously described. A third step 114 may include contacting the shaving surface of the first shaving razor 10 with the transparent first surface. In a fourth step 116 the shaving surface of the first shaving razor against the transparent first surface may be illustrated through a transparent second surface that is opposite the first surface (e.g., looking at the shaving surface through a plane of glass). The first shaving razor may be moved along the transparent surface (step 118) to illustrate the release of a first substance from a first component of the first shaving razor through the transparent surfaces 42a and 46a (step 120).
The shaving demonstration method 100 illustrates shaving performance for a single shaving razor. However, it may be more desirable to provide a shaving demonstration method that compares two different razors. Referring to FIG. 8, a schematic representation of a second shaving demonstration method 130 is illustrated. The second shaving demonstration method 130 may comprise a first step 132 of providing a first shaving razor having a shaving surface with at least one blade, such as the first shaving razor 10 as previously described. A second shaving razor having a shaving surface with at least one blade (such as the first shaving razor 30 as previously described) may be provided in step 134. In step 136, a transparent first surface may be provided, such as the transparent first surface 42a,42b as previously described. Step 138 may include contacting the transparent first surface with the shaving surface of the first shaving razor 10 and the shaving surface of the second shaving razor 30. In step 140 the shaving surface of the first shaving razor and the shaving surface of the second shaving razor 30 may be illustrated against the transparent first surface through a transparent second surface that is opposite the first surface (e.g., looking at the shaving surfaces through a plane of glass). The first shaving razor and the second shaving razors may be moved along the transparent surface (step 142) to illustrate the release of a first substance from a first component of the first shaving razor through the transparent surfaces 42a,42b and 46a, 46b (step 144). In certain embodiments, the second shaving razor may not release any substance or may release a substance from a different component or a component in a different position than the first shaving razor.
It is understood that the various steps of the shaving demonstration method 100 and the second shaving demonstration method 130 may include live demonstrations, video filming, animations, illustrations, computer simulated models, or any combination thereof. It is also understood that any of the steps may be performed in any order.
