Description

Technical Field

[0001] This invention relates to personal care products, and more specifically to those products that include both skin treatments and / or hair removal.

[0002] Cross-references to related applications

[0003] This application relates to a co-pending application serial number (63 / 177,257) filed on the same date as this application and by the same assignee, which is not acknowledged as prior art to the invention by virtue of its reference in the cross-reference section. The full text of that co-pending application is incorporated herein by reference. Background Technology

[0004] Personal care products described in the prior art are used for skin treatment or hair removal. Some known prior art discloses razors for hair removal with perforated blades, wherein the perforations have sharp cutting edges. In other prior art, wet razors have linear blades or electric razors have a cutting system consisting of scissor blades that move under a perforated foil to cut hair. It is advantageous not only for hygiene reasons but also to allow the product to function effectively and continuously over extended periods, by removing debris (such as cut hair and shaving agents) that accumulates around the cutting edges of these products.

[0005] Existing technologies provide the removal of debris (such as hair and shaving formulation compositions) by allowing fluid (e.g., water) to flow between the blades. However, a drawback of many of these products is that the area provided for debris removal is insufficient. For example, in wet razors, the area for debris removal is provided within the razor blade holder, and specifically, the span between the blades is very small, and often not all debris can be removed by rinsing. The user taps the blades against a hard surface such as a sink. Debris stuck between the blades affects the subsequent shaving performance of the blade holder, which can lead to unwanted cuts and nicks. In prior art reference U.S. Patent 10,500,743, which discloses a dry razor, hair dust is collected in an encapsulated chamber, and when two rinsing openings are positioned below the chamber for water flow to remove hair dust, valves are installed in the encapsulated chamber covering these rinsing channels, thus restricting the flow direction and complicating the system, ultimately resulting in inefficiency in removing the collected hair dust.

[0006] Furthermore, many existing razors are designed specifically for hair removal and are therefore not typically optimized for effective skin treatment purposes.

[0007] Personal care products optimized for purposes such as skin exfoliation or dermaplaning, which include cutting blades, are typically made of a metal foil with cutting blades protruding onto a foil surface. These products usually do not include a system for rinsing off skin flakes and other debris, including hair.

[0008] Metal foils in this art are typically formed and shaped to provide convex or dome-shaped treatment surfaces for improving skin contact along curved skin surfaces. A disadvantage of this configuration is that the skin contact area is minimal on extended, flat body parts such as the legs or back, resulting in inefficient processing that takes a long time to complete.

[0009] The aim is to provide an optimized system for removing debris from personal care products, optimized for both skin treatment and hair removal.

[0010] It is desirable to provide a debris removal structure optimized for both skin treatment and hair removal in personal care products, the debris removal structure including structural features such as a flat treatment surface for good skin contact across extended flat body parts. Summary of the Invention

[0011] This invention relates to a personal care product, the personal care product comprising:

[0012] The upper part of the product; a housing at the upper part of the product, the housing including a top opening and an outer wall; a processing piece disposed on the top opening of the housing; and one or more windows disposed in the outer wall of the housing.

[0013] According to a novel aspect of the invention, fluid can flow through one or more windows or through a plurality of holes in the processing sheet, or any combination thereof. The fluid flows into or out of the one or more windows, or any combination thereof, in a direction parallel to the processing sheet. The fluid is water. The fluid flow removes debris from the lower surface of the processing sheet, the cavity of the housing, or both.

[0014] In other aspects of the invention, the one or more windows include the same shape as at least one other window among the one or more windows. The one or more windows include two or three windows. Further, at least one of the one or more windows includes a polygonal or circular shape.

[0015] According to another aspect, the one or more windows include two opposing windows. At least one of the one or more windows includes a rounded corner.

[0016] In other aspects of the invention, the outer wall extends along the outer surface of the upper end of the personal care product, and the treatment sheet is visible from the one or more windows. Further, the treatment sheet includes a plurality of holes.

[0017] On the other hand, the housing includes a floor surface. The floor surface is either flat or shaped. The shaped floor surface includes a dome or conical shape. The shape of the shaped floor surface does not obstruct the one or more windows.

[0018] In this invention, the housing at the upper end of the product can be released from the lower end of the personal care product.

[0019] Furthermore, the housing has a substantially cylindrical shape and includes a cavity.

[0036] Figure 11 Figure 5 depicts the personal care product of the present invention in use. Detailed Implementation

[0037] In this invention, the personal care product includes a treatment sheet with perforations disposed at an opening in the top of a housing located at the upper end of the product. The housing includes a cavity surrounded by walls, the walls including windows in the outer wall of the housing. The windows provide an inlet area for rinsing fluid (e.g., water) to remove or rinse away debris after use of the personal care product. The flow paths through the windows and perforations of the treatment sheet are multidirectional.

[0038] Additionally, the frame member holds the treatment sheet onto the housing portion of the personal care product. If a tab is present along the outer surface of the frame member, the tab can help secure the treatment sheet to the housing by inserting it into a notch on the upper flange of the housing window.

[0039] The treatment sheet at the top of the housing includes multiple holes. Each hole includes a non-linear portion along its inner periphery. The inner periphery of each hole is sharpened to provide a cutting edge. More durable cutting edges can be made of ceramic-like materials or crystals like silicon, sapphire, or diamond. These materials are not malleable like metals and are generally brittle, meaning they fracture with little elastic deformation and no significant plastic deformation, and therefore cannot be formed into, for example, dome or convex shapes, but rather as flat sheets. This type of flat treatment surface improves treatment effectiveness, such as the removal of hair or exfoliation of skin on extended, flat surfaces (e.g., legs, chest, and back).

[0040] As used herein, the term "product" includes an upper end and a lower end, wherein the upper and lower ends are permanently or releasably coupled together. The upper end of the product of the present invention typically includes, but is not limited to, a processing element, a housing, a sheet, and a frame member.

[0041] Ideally, the processed sheet should be flat. A "flat" material typically has a planar surface without protrusions or depressions. As used herein, "flat" and "planar" can be used interchangeably.

[0042] Ideally, the processing sheet should also be rigid. "Rigid" material means that the material is not flexible and cannot be easily bent.

[0043] The function of treatment sheets in personal care products is to both remove hair and treat the skin, which is achieved through the structure of the treatment sheets described above.

[0044] The treatment sheet of this invention is ideally made of a solid, non-corrosive material. The treatment sheet can be made of amorphous materials such as glass, crystalline materials such as silicon, diamond, sapphire, polycrystalline materials such as silicon, ceramics, or metals (e.g., steel), or any combination thereof. These materials can be shaped into rigid, planar treatment sheets with pores. Although they are rigid, these materials can be quite brittle. "Brittle" materials are those that typically fracture under load with little elastic or plastic deformation. Treatment sheets made of such materials, such as silicon and diamond, may break or shatter into pieces if a personal care product is dropped, if it comes into contact with force, or is subjected to a large impact. The treatment sheet substrate can be made of silicon, and the cutting edge can be made of diamond.

[0045] As used herein, the term "shell" may include, but is not limited to, structures located at the top of the product. The shell in this invention carries the processing sheet and preferably includes a cavity with a window defined by pillars or supports. The shell typically has a substantially cylindrical shape, although any feasible shape is contemplated in this invention.

[0046] As used in this invention, the term "debris" may include, but is not limited to, dead skin cells, hair (e.g., including terminal hair and vellus hair), treatment or shaving preparations, dirt, oil, and other substances removed from or applied to the surface of the skin before and during use.

[0047] As used herein, the term "cavity" refers to an open area or volume of the housing. The cavity is preferably a volume portion formed directly beneath the treatment sheet, in which debris from the use of the personal care product is collected and easily removed (e.g., by rinsing with water). Debris may adhere to the lower surface of the treatment sheet or fall into the cavity. Debris is removed from the lower surface of the treatment sheet in the cavity by circulating water, pressurized air, or by draining the debris through an opening in the housing wall, or by other feasible methods.

[0048] In this invention, such as Figure 4A and Figure 4B As shown, cavity 290 abuts against plane C1 defined by the lower surface 42 of the processing piece, and generally extends along plane C2 defined by the inner pillar wall 217 of housing 20 (e.g., pillar), extending to and above the floor surface 280 of housing 20. For clarity, the volume of cavity 290 is... Figure 4A and Figure 4B The middle is drawn with a shading line.

[0049] The height H2 of the cavity can be the height H1 of the total length of the personal care product (e.g., Figure 1A The cavity height H2 is at least approximately one-fifteenth of the height H3 of one of the plurality of pillars, or larger if feasible. Ideally, it is the height H3 of the tallest of the plurality of pillars. This large volume, adjacent to the treatment sheet and including a window in the housing wall, significantly improves the removal of debris from personal care products.

[0050] As used herein, the term "window" refers to an opening or hole in the housing wall. Ideally, the window is cut out from or integrally formed with the outer wall of the housing. The window may be shaped such that it does not extend too far into the interior of the lower end of the product (e.g., the handle) to provide the largest possible cavity. Ideally, the window is formed along a surface extending from the lower end of the personal care product. The sides of the window are pillars or supports formed in the outer wall of the housing. The terms "pillar" and "support" are used interchangeably herein and are generally located on the sides of the window.

[0051] The window communicates with a cavity inside the housing. In this way, for example, rinsing fluid can flow freely across one side of the window, through the cavity, to the other side of the window located outside the upper end of the product. Therefore, when personal care products are used and debris (e.g., cut hair, dead skin cells, etc.) is collected from the action of the treatment sheet, the debris will be collected near the treatment sheet (e.g., on the lower surface 42 of the treatment sheet), and the debris located inside the cavity can be easily removed through the window. Water or other cleaning fluids are preferably used to remove debris, although other techniques such as pressurized air can also be used for the window of the present invention. The size, shape, and location of the window will be described in detail herein.

[0052] This document describes polygonal and circular windows; however, any arrangement of the shape and size of the windows within the housing is contemplated in this invention. Therefore, the supports or pillars on the sides of the window can also have any shape, conformal to the window or otherwise. Furthermore, any feasible patterns and positions of the windows or supports within the housing are contemplated in this invention.

[0053] The term "frame member" refers to a component on a personal care product used to align and hold the treatment sheet and serve as a skin contact surface. The treatment sheet is aligned and positioned on the upper surface of the personal care product's casing. For ease of understanding, the frame member can be thought of as a "frame," such as those used for photographs, and the treatment sheet can be thought of as the "glass" behind the frame. Using this metaphor, the frame member is preferably shaped like the outer perimeter of the treatment sheet, but slightly larger.

[0054] This invention envisions an embodiment of the personal care product shown in Figures 1 to 4. (Reference) Figure 1A , Figure 1B and Figure 1C A perspective view, a top view, and a side view of a personal care product 10 are shown. The personal care product includes an upper end 11 and a lower end 12, the lower end including a handle 30. The upper end 11 includes a housing 20 having a carrier 230, a base 240, and sidewalls 210, the sidewalls having windows 260 separated by pillars or supports 220 or located on their sides. The carrier 230 has an uppermost surface 213 with a top opening 205. A treatment sheet 40 is disposed on the top opening of the housing 20, and a frame member 50 is disposed on the treatment sheet 40. The treatment sheet 40 has a generally circular shape, but any shape is contemplated in this invention. The treatment sheet includes a hole 430 in which a cutting blade 435 is formed. The cutting blade in the treatment sheet serves to remove hair and peel the user's skin.

[0055] Window 260 is an opening in the sidewall 210 of the housing of the present invention, which allows for the removal of debris such as cut hair, shaving agents, dead skin cells, etc., collected during the operation of the personal care product. These windows 260 will be described in detail below.

[0056] Figure 2 The upper part 11 of the personal care product 10 is depicted along... Figure 1A A perspective view of section AA in the diagram shows the personal care product comprising a housing 20 having a window 260 separated by pillars 220. Although in Figure 2 The illustration shows three windows 260 and two pillars or supports 220, but any number of windows 260 and any number of supports 220 are contemplated in this invention.

[0057] The housing also includes an upper surface 214 having an inner periphery 206 surrounding the top opening 205 and a housing wall 210.

[0058] The tab 550 (if present on the frame member 50) can also be bent to extend around or into the housing wall 210 and into the housing window 260. The tab 550 is shown in FIG. 5 (an alternative embodiment of the invention).

[0059] The housing window 260 is used to help flush out debris, such as dead skin cells, shaving agents, or hair (e.g., vellus hair), generated or accumulated during the use of personal care product 10. Several embodiments of the window shape, size, and location are described herein.

[0060] refer to Figure 3 The exploded cross-sectional view of the upper part of the personal care product 10 is depicted along... Figure 1C An exploded cross-sectional view taken from section BB shows the housing 20, window 260, strut 220, treatment panel 40, and frame member 50 disposed thereon. Figure 3 As shown, the carrier 230 of the retainer 20 includes an upper housing surface 214 configured to carry or hold the processing sheet 40 in place. As shown, at the periphery 45 of the processing sheet 40, the outer portion of the lower surface 42 of the processing sheet 40 contacts the uppermost surface 214 of the housing. The carrier 230 also has a lower flange 262 that forms the upper flange of the window 260.

[0061] Figure 3 The diagram also shows a base 240 according to a preferred embodiment of the invention, wherein a support post 220 is disposed between the support body 230 and the base. The outer surface of the housing wall 210 extends from the lower outer periphery 207 of the support body 230 to the upper outer periphery 208 of the base 240. The support body and the base are generally parallel, and the support post 220 is generally perpendicular to both the support body and the base; however, any orientation of these components is contemplated in the invention, for example, as shown in FIG. 5. Figure 3In the diagram, the support column 220 is shaded and shown as positioned between the floor surface 280 of the base 240 and the lower flange 262 of the window 260. The support column 220 has depth, width, and height. In this embodiment, the height of the support column 220 typically defines the height of the window 260.

[0062] Ideally, the window 260 formed between the pillars 220 has a rounded corner 268 at the interface between the pillar and the flange 262 or the floor surface 280. Since it is not a sharp (e.g., 90-degree) corner, the rounded corner 268 advantageously allows debris (e.g., collected under the treatment sheet 40 during use) to be easily removed from the window by not remaining stuck in a sharp corner.

[0063] Turning Figure 4A and Figure 4B They show an embodiment of the upper end 11 of a personal care product 10 having a housing window 260 and a support 220, respectively along... Figure 1C Cross-sectional views of AA and BB. Figure 4A The figure depicts the cavity 290 of the present invention formed within the housing, showing a cross-section along the window 260. Figure 4B The shell is depicted, and the figure shows a cross-section with strut 220.

[0064] Figure 4A and Figure 4B The cavity 290 is shown as adjacent to a plane C1 defined by the lower surface 42 of the entire processing sheet 40, extending downward along a plane C2 defined by the inner column wall 217 of the housing 20, and extending to and above the floor surface 280 of the housing 20. For clarity, the volume of the cavity 290 is... Figure 4A and Figure 4B The areas are all shaded. The cavity 290, located directly beneath the processing plate (e.g., where debris falls through the hole 430 of the processing plate 40), and the window positioned between the support pillars 220, allow debris to be easily removed, flushed away, or removed from the device. Regarding... Figures 9A-9F The debris removal process is shown and described in more detail.

[0065] Figure 5A A perspective view is shown, and Figure 5B An exploded perspective view depicting an alternative embodiment of the personal care product of the present invention is shown. In this embodiment, the treatment sheet 40 has a hexagonal shape and is disposed on the top opening 205 of the housing 20. The carrier 230 is disposed at an angle relative to the base 240. A support 220 is disposed between the carrier and the base; except that the support 220 of FIG. 5 has varying dimensions compared to FIGS. 1 through 4, as will be described in more detail below.

[0066] in addition, Figure 5Aand Figure 5B The frame member 50 of the embodiment includes a plurality of tabs 550. The frame member 50 facilitates the alignment, placement, retention, and protection of the treatment sheet. The frame member 50 also serves as a skin contact surface during use. The tabs 550 of the frame member 50 also help retain the treatment sheet on the personal care product. The housing window 260 shown in FIG. 5 can be used to help the tabs 550 of the frame member 50 retain the treatment sheet 40 on the housing 20, including but not limited to, by using a notch 215 formed in the upper flange 262 of the window 260.

[0067] Ideally, the number of windows equals the number of tabs, but any number of desired windows and tabs are contemplated in this invention. Several embodiments regarding window shape, size, and location are described below.

[0068] exist Figure 6 In the figure, a cross-sectional view taken along line CC in Figure 5 depicts a portion of the inner wall 217 of the housing of the cavity 290 and the support 220 of product 10 in Figure 5. Figure 6 In the personal care product, the support 220' at the front is shorter than the supports 220" in the rest of the casing (including those shown at the rear of the casing). This is due to the fact that the support 230 is angled relative to the base 240. Although in Figure 6 There is no window 260 at the front of the housing 20, but if feasible, a small window may be provided between the two pillars.

[0069] exist Figures 7A to 7C Figure 5 shows three views of a housing 20 with windows 260, representing an embodiment of the personal care product of the present invention. The housing 20 is shown detached from the lower end 12, the treatment piece 40, and the frame member 50, with a top opening 205 exposed. Three windows are depicted in the housing 20. Window 260a is on the left side, window 260b is on the rear side, and window 260c is on the right side of the housing 20. Figure 7A As shown in the rear view of the housing 20, window 260b comprises a rectangular shape, while Figure 7B The window 260a shown on the left and Figure 7C The windows 260c shown on the right side of the housing 20 all have the same triangular shape.

[0070] Note that windows 260a, 260b, and 260c ideally have rounded corners 268. By not having sharp edges, debris is more easily removed by the flushing fluid and does not remain stuck in the cavity 290 at the sharp edges of the window.

[0071] The housing 20 also has an upper surface 214, one or more pillars 220, and a floor surface 280. The pillars 220 are positioned between the support 230 and the base 240, forming windows 260a, 260b, and 260c within the housing, while also effectively forming part of a window “frame.” The floor surface 280 is shown as a flat, planar surface, much like a floor in a home. The advantage of having a flat housing floor surface 280 is that the window 260a on the left side of the housing has a “view” across the other windows 260b or 260c on the rear and right sides of the housing. This “view” allows flushing fluid (such as water) to flow unimpeded from one window to another to wash away debris when it accumulates in the cavity 290 (e.g., below the treatment piece 40). Furthermore, because the floor surface 280 is a flat, solid surface adjacent to the lower end 12 of the product, it prevents any debris from entering the handle interior. The present invention envisions that the floor surface 280 of the housing can be formed by any shaped surface opposite to a flat surface, and embodiments thereof will be described below.

[0072] Figures 8A to 8C Three perspective views are depicted of an alternative embodiment of a personal care product according to the invention, having a housing 20', the housing having a window and a support. Figures 8A to 8C There are three windows, 260a', 260b', and 260c', each with an annular or circular shape. While they are all the same shape, the difference lies in the size: the windows at the rear of the housing are larger than those on the left and right sides. As with Figures 5 through 7, there are no windows at the front of the housing. The circular windows facilitate easy debris removal.

[0073] Turn now Figures 9A to 9F These figures illustrate various flow paths for removing debris through the housing window and processing plate of the embodiments of the invention shown in Figures 5 to 7. For debris removal, a flushing agent is ideal, including but not limited to water, detergents (such as alcohol or surfactant solutions), or gases (such as air or pressurized gas). Regardless of the type of flushing agent, the flow path for debris removal is generally the same. Figure 9A In the diagram, flow path 901 is shown as starting from the external environment 900 and entering the top of the treatment sheet, passing through the holes 430 of the treatment sheet, entering the cavity 290, and exiting through the side window 260c. Therefore, flushing agent can be poured from or inserted from the top of the treatment sheet 40 to be delivered into the cavity 290 through the holes 430 to flush out debris collected below the treatment sheet 40 and discharged through the window 260c. Figure 9B middle, Figure 9A The flow path 901 is shown from the rear side of the product top 11, starting from the top of the processing piece 40, flowing through the hole 430, entering the cavity 290, and flowing out of any one or all of windows 260a, 260b and 260c.

[0074] exist Figure 9C The diagram illustrates a second flow path 902, in which the flushing agent begins at side window 260c and exits at side window 260a, which is directly opposite window 260c. The flow path can begin at any window and remove debris from beneath the processing sheet through any other window. For example, the flushing agent can begin at side window 260a and exit at side window 260c.

[0075] exist Figure 9D middle, Figure 9C The flow path is shown in the rear perspective view from the top 11 of the product. As shown, flow path 902 initiates the flow of flushing agent from side window 260c and exits from side window 260a, which is directly opposite window 260c and / or rear window 260b. Similarly, the flow can begin in side window 260a or rear window 260b and be removed from any remaining window.

[0076] exist Figure 9E In, it is shown Figure 9C The second flow path 902, in which the flushing agent begins at side window 260c and exits at side window 260a, which is directly opposite window 260c. The flow path can begin at any window and exit from any other window. For example, the flushing agent can begin at side window 260a and exit at side window 260c. Additionally, the third flow path 903 also begins at side window 260c and flows into cavity 290, then flows upward through orifice 430 and exits into the external environment 900. Figure 9F middle, Figure 9E The flow path is shown in the rear perspective view from the top of the product 11. As shown, the flow path 902 initiates the flow of flushing agent from the side window 260c and flows out of the side window 260a, which is directly opposite the window 260c or the rear window 260b. Figure 9E The flow path 903 is in Figure 9F As shown in the rear perspective view, the flushing agent begins at the side window 260c, flows into the cavity 290, and flows upward into the treatment plate through the orifice 430 to reach the external environment 900. Here, the flushing agent flow path can also begin at any window and then be removed through the orifice.

[0077] While floor surface 280 has been described to date as flat and solid (e.g., much like a floor in a home), the present invention contemplates floor surfaces with one or more curved surfaces. For example, several shapes can be combined into the floor surface of the personal care product housing of the present invention. [Turn] Figures 10A to 10F These illustrate three alternative embodiments for floor surfaces used in this invention. Figure 10A and Figure 10BIn the first alternative embodiment shown, the side and rear views of the housing have a floor surface 280, which includes a dome-shaped protrusion 282 projecting from a central region of the floor surface 280. The dome-shaped protrusion 282 ideally includes a portion of a spherical shape, such as a hemisphere. The dome-shaped protrusion 282 extends upward from the floor 280 into the cavity 290 such that the dome-shaped portion faces the processing piece 40, and the base of the dome is positioned on the floor surface 280. Figure 10B As can be seen, the dome-shaped protrusion 282 does not have the height or width to obstruct window 260b or any other window, which is ideal for maintaining effective debris removal. With the dome-shaped protrusion 282 formed in this way, when debris is flushed away from the underside of the treatment plate and from within the cavity, the flow path of the flushing agent and debris is guided downwards to slide over the dome-shaped protrusion and exit windows 260a, 260b, and 260c, just like a flat floor surface, but in this case, the dome-shaped protrusion further accelerates the drainage for fluid discharge and debris removal. Similarly, for flushing agent entering through any of windows 260a, 260b, and 260c, the flow path of the flushing agent and debris is guided upwards to remove debris from the treatment plate.

[0078] exist Figure 10C and Figure 10D In the second alternative embodiment shown, the side and rear views of the housing have a floor surface 280, which includes a funnel-shaped protrusion 284 projecting from a central region of the floor surface 280. The funnel-shaped protrusion 284 ideally has a conical apex or is part of a funnel. The funnel-shaped protrusion 284 extends upward from the floor 280 into the cavity 290 such that the apex faces the processing plate 40. Figure 10D As can be seen, the funnel-shaped protrusion 284 does not have the height or width to obstruct window 260b or any other window. This is ideal for maintaining effective debris removal. With the funnel-shaped protrusion 284 formed in this way, when debris is flushed away from the underside of the treatment plate and from within the cavity, the flow path of the flushing agent and debris is guided downward to slide over the outer surface of the funnel-shaped protrusion 284 and exit windows 260a, 260b, and 260c, just like a flat floor surface, but in this case, the funnel-shaped protrusion further accelerates the drainage for fluid discharge and debris removal.

[0079] exist Figure 10E and 10FIn the third alternative embodiment shown, the side and rear views of the housing have a floor surface 280, which includes a tapered protrusion 286 projecting from a central region of the floor surface 280. The tapered protrusion 286, having a apex 286a, ideally includes a tapered shape or part of a cone, such as the top portion of a cone including its apex. The tapered protrusion 286 extends upward from the floor 280 into the cavity 290 such that the apex faces the processing piece 40. Figure 10F As can be seen, the conical protrusion 286 does not have a height or width that would completely block or obstruct window 260b or any other window. This is ideal for maintaining effective debris removal. With the conical protrusion 286 formed in this way, when debris is flushed away from the underside of the treatment plate and from within the cavity, the flow path of the flushing agent and debris is guided downward to slide over the outer surface of the conical protrusion 286 and exit windows 260a, 260b, and 260c, just like a flat floor surface, but in this case, the conical protrusion further accelerates the drainage for fluid discharge and debris removal.

[0080] Figure 11 A personal care product 10 is shown for use on a user's skin. It can be seen that the user holds the handle 30 of the personal care product 10 of the present invention on a portion of their face. The treatment sheet 40 is held facing and pressed upward against the skin, such that hair removal and exfoliation of the dermis occur as the product moves upward, downward, and around the user's skin. Debris 950 is collected below the treatment sheet 40 and in the housing cavity 290. A rinse and, as... Figures 9A to 9F The flow path described herein is used to remove these debris.

[0081] The invention also envisions any other feasible arrangements of windows and other components in personal care products.

[0082] The examples presented herein are not intended to be actual views of any particular substrate, device (e.g., apparatus, system, etc.) or method, but are merely idealized and / or illustrative representations for describing and illustrating various embodiments of this disclosure.

[0083] The dimensions and values ​​disclosed herein should not be construed as strictly limited to the precise numerical values ​​cited. Rather, unless otherwise specified, each such dimension is intended to represent the value and a range around which it is functionally equivalent. For example, a dimension disclosed as “40 mm” is intended to represent “about 40 mm”. As used herein, the term “about” generally means approximately or around. As an example, when a range of values ​​is given, for example, if this document discloses “about 4 to about 40” or “4 to 40”, the invention considers the values ​​“4” and “40” and a range around which each of 4 and 40 is functionally equivalent, which can generally be added to or subtracted from each value by 10%. Thus, for clarity, if a reference is made to being described as “4 to 40”, this means that it can be a range functionally equivalent to 4 and a range functionally equivalent to 40, or “about 4 to about 40”. The latter refers to the range “3.6 to 44” included in the invention, since the range of 3.6 to 4.4 represents 4 plus or minus 10%, respectively, and the range of 36 to 44 represents 40 plus or minus 10%, respectively.

[0084] Unless expressly excluded or otherwise limited, every reference cited herein, including any cross-references or related patents or patent applications, and any patent application or patent claiming priority to or benefiting from it, is incorporated herein by reference in its entirety. Reference to any reference is not an endorsement of it as prior art to any disclosed or protected art herein, nor is it an endorsement of any such invention, either on its own or in combination with any one or more references. Furthermore, where any meaning or definition of a term in this invention conflicts with any meaning or definition of the same term in referenced documents, the meaning or definition given to that term in this invention shall prevail.

[0085] While specific embodiments of the invention have been illustrated and described, it will be apparent to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. Therefore, it is intended that all such changes and modifications falling within the scope of the invention be covered in the appended claims.
