Description

Technical Field

[0001] The present invention relates to razors, and more particularly to razor systems having a razor blade holder assembly releasably mounted to the handle. Background Technology

[0002] Shaving systems typically consist of a handle and a replaceable blade holder, in which one or more blades are mounted within a housing. Various types of blades are known in the art, including linear blades found in typical razors, as well as round blades. Once the blades in the blade holder become dull due to use, the blade holder is discarded and replaced with a new one, which is then mounted on the handle. These types of shaving systems have become common by utilizing various attachment schemes to attach the blade holder to the handle. This attachment scheme allows consumers to easily, repeatedly, efficiently, and intuitively load new blade holders from the handle and remove used blade holders, and provides the necessary holding force to maintain the integrity of the handle-to-blade holder attachment during shaving.

[0003] The attachment scheme must be robust enough to provide the necessary holding force to maintain the integrity of the shank-to-blade holder attachment during shaving. The attachment of the razor blade holder to the razor shank provides sufficient holding force to secure the razor blade holder to the razor shank under a wide range of shaving conditions. However, attachment mechanisms are often not intuitive and only allow for specific orientations that enable correct attachment. Furthermore, such systems often include pop-out mechanisms, which can increase cost and complexity.

[0004] There is a growing market for higher-end shaving heads, which are typically made of various metals, making them heavier. Heavier shaving heads provide a more comfortable feel in the hand during shaving. Some consumers believe that heavier shaving heads offer improved control during shaving. However, the increased weight of the shaving head increases the likelihood of damage to the attachment mechanism if it falls off. Therefore, there is a need for simpler, more robust, more intuitive, and more reliable shaving head-to-blade holder connections. Summary of the Invention

[0005] In one aspect, the invention is generally characterized by a shaving system having a handle with a distal end and a proximal end. A shaving blade holder assembly is mounted on the proximal end of the handle. The shaving blade holder assembly includes a shaving surface. A coupling interface exists between the shaving assembly and the handle. The coupling interface includes a first surface separable from a second surface. The first surface defines a rinsing cavity. An attachment extends from the second surface and enters the rinsing cavity. The first surface is magnetically coupled to the second surface.

[0006] In another aspect, the invention is generally characterized by a shaving system having a handle with a proximal end having a rounded and flat first surface. The first surface defines a rinsing cavity. A shaving blade holder assembly is mounted on the proximal end of the handle. The shaving blade holder assembly includes a shaving surface mounted to a housing. The shaving surface has a plurality of openings communicating with the rinsing cavity. The shaving blade holder assembly is removably secured to the handle by magnetic force between the first surface and a second surface on the housing of the shaving blade holder assembly.

[0007] In another aspect, the invention is generally characterized by a handle for a shaving system having a proximal end and a distal end. The proximal end has a rounded and flat first surface. A gripping portion is located between the proximal end and the distal end. The first surface includes at least one magnetic element.

[0008] On another front, the invention is generally characterized by a handle for a shaving system having a proximal end and a distal end. The proximal end has a first surface defining a rinsing cavity having a depth of approximately 100 mm. 2 Approximately 300mm 2 The area is defined by the gripping portion located between the proximal end and the distal end. The gripping portion defines an opening communicating with the flushing chamber.

[0009] In another aspect, the invention is generally characterized by a razor blade holder assembly having a housing with a circular attachment defining a cavity extending through the housing. A shaving surface is mounted to the housing. A gasket is mounted above the circular attachment and onto a flange of the housing. The gasket is made of a ferromagnetic metal.

[0010] In another aspect, the invention is generally characterized by a razor blade holder assembly having a housing with an attachment defining a cavity extending through the housing. A shaving surface is mounted to the housing. The shaving surface has a plurality of openings communicating with the cavity.

[0021] Figure 10 For from Figure 1 A perspective view of the handle. Detailed Implementation

[0022] refer to Figure 1 The diagram illustrates a perspective view of a shaving system 10. The shaving system 10 may include a shank 12 and a blade holder assembly 14. In some embodiments, the blade holder assembly 14 may be mounted to the top surface of the shank 12. The blade holder assembly 14 may be a replaced component of the shaving system 10. The shank 12 may be made of any suitable material. For example, the shank 12 may be made of various metals, polymers, elastomers, rubber, any other suitable material, or any combination thereof. It should be understood that using a higher-quality material, such as metal, may increase the weight of the shank 12. The shank may be made by molding, injection molding, insert molding, casting, extrusion, machining, or any combination thereof.

[0023] The razor blade holder assembly 14 can be releasably attached to the handle 12. For example, Figure 1A shaving system 10 is illustrated, wherein the razor blade holder assembly 14 is separate from the handle 12. Therefore, the razor blade holder assembly 14 can be replaced after the consumer has reached the desired number of uses. As will be described in more detail below, the razor system 10 may incorporate a coupling interface 16 between the handle 12 and the razor blade holder assembly 14 to allow for quick and intuitive attachment and removal of the razor blade holder assembly 14 from the handle 12. The coupling interface 16 may include a first surface 18 defining a flushing chamber 20 and an attachment 22 extending into the flushing chamber 20. The handle 12 may include a flange 25 positioned within the flushing chamber 20. The flushing chamber 20 may have a length of 100 mm, as measured at the first surface 18. 2 Or a larger area. For example, the flushing chamber 20 may have an area of ​​approximately 100 mm. 2 Approximately 300mm 2 Or more preferably about 125mm 2 Up to 175mm 2 The area is designed to allow for thorough rinsing of shaving debris, while also allowing the razor blade holder assembly 14 to be small enough to reach the area between the nose and mouth. In some embodiments, the distance from the flange 25 to the first surface can be from about 3 mm to about 6 mm. The attachment 22 may be spaced apart from the flange 25 to allow for proper placement of the razor blade holder assembly 14 on the first surface 18, for example, as... Figure 7 As shown.

[0024] The attachment 22 may extend from a second surface 24, which is magnetically coupled to the first surface 18. Therefore, the first surface 18 can be separated from the second surface 24 when the magnetic attraction is overcome. It should be understood that portions of the coupling interface 16 are interchangeable between the handle 12 and the razor blade holder assembly 14, allowing the razor blade holder assembly 14 to be releasably attached to the handle 12. The coupling interface 16 provides sufficient magnetic force to attract the razor blade holder assembly 14 to the handle 12 and to hold the razor blade holder assembly 14 on the handle 12 during shaving and when not shaving (e.g., between shaving strokes, during rinsing, and when the shaving system 10 is not in use). It is believed, without being bound by theory, that a force of about 2 Newtons to about 10 Newtons, and more preferably about 3 Newtons to about 7 Newtons, is sufficient to provide optimal attraction while also preventing the razor blade holder assembly 14 from rotating relative to the handle 12 during shaving strokes. For example, the attraction force may be greater than the weight of the razor blade holder assembly 14. In some embodiments, the attractive force can facilitate the razor blade holder assembly 14 jumping onto the handle 14. However, the attractive force can be low enough that the razor blade holder assembly 14 can be easily removed from the handle 12 by the consumer. Furthermore, the razor blade holder assembly 14 can be configured to rotate relative to the handle 12 before shaving. For example, a user may notice a wear pattern forming in a specific area of ​​the shaving surface 48 after repeated use in a particular orientation of the handle 12 to the razor blade holder assembly 14. Therefore, the user can easily adjust the orientation of the shaving surface 48 by rotating the razor blade holder assembly 14 (relative to the handle 12).

[0025] The handle 12 may have a proximal end 26, a distal end 28, and a gripping portion 30 located between the proximal end 26 and the distal end 28. The distal end 28 may include an enlarged spherical portion 32. The gripping portion 30 may taper gradually from the enlarged spherical portion 32 to a reduced intermediate portion 34. The gripping portion 30 may also taper gradually from the reduced intermediate portion 34 to the enlarged proximal end portion 36, thereby forming an hourglass shape. The enlarged proximal end portion 36 may define an opening 40. The opening 40 may be generally perpendicular to the flushing chamber 20. In some embodiments, the proximal end 26 of the handle may include a first surface (e.g., a top surface) 18. The first surface 18 may be flat (e.g., without any protrusions or walls extending therefrom that may restrict rotation of the razor blade holder assembly 14) and have a generally circular shape. As will be described in more detail below, the geometry of the first surface 18 may allow the razor blade holder assembly to rotate relative to the handle 12. The rinsing chamber 20 defined by the first surface 18 extends to the opening 40. Thus, the rinsing chamber 20 communicates with the opening 40 so that water and razor debris can be rinsed away from the handle 12 and the razor blade holder assembly 14.

[0026] The razor blade holder assembly 14 may include a housing 42 having a proximal end 44 and a distal end 46. A shaving surface 48 may be mounted to the housing 42 (e.g., at the proximal end 44). The shaving surface 48 can be used to remove hair or skin (e.g., exfoliation). In some embodiments, the shaving surface 48 may include a plurality of circular cutting edges 50, each circular cutting edge defining a corresponding opening 52 to facilitate the removal of shaving debris and water. The circular cutting edges 50 allow hair to be cut as it extends into the associated opening 52. Because the circular cutting edges 50 surround the opening 52, hair can be cut as the shaving surface 48 passes over hair in any direction, thus allowing multi-directional hair cutting. Cutting hair in multiple directions eliminates the need for a specific orientation of the shank 12 relative to the razor blade holder assembly 14, which simplifies attachment. In some embodiments, the housing 42 may include an attachment 22 located at the distal end of the housing 42. The attachment 22 may be configured to be received within a rinse chamber 20. The attachment 22 facilitates the attachment and alignment of the razor blade holder assembly 14 to the shank 12. For example, the user can align the attachment 22 with the flushing chamber 20. In some embodiments, the attachment 22 and the flushing chamber 20 may be circular. Therefore, no specific orientation or rotation is required to align the attachment 22 with the flushing chamber 20. The first surface 18 is rotatable relative to the second surface 24 to allow the razor blade holder assembly 14 to rotate relative to the shank 12. For example, the attachment 22 may be attached to the shank 12 at 360 degrees. Keyed designs can lead to consumer confusion and frustration because consumers need to align certain features on the shank with other features on the blade holder. The shaving surface 48 (and the circular cutting edge 50) may be made of various metals (such as stainless steel) or ceramic materials (such as silicon dioxide or crystals such as silicon, sapphire, or diamond).

[0027] refer to Figure 2 Examples Figure 1 Bottom perspective view of the razor blade holder assembly 14. The attachment 22 may be generally circular in shape and is defined with a circular cutting blade 50. Figure 1 The opening 52 communicates with the cavity 54. The attachment 22 may extend beyond the second surface 24 to reach the distal end 56. In some embodiments, the cavity 54 may be funnel-shaped, such that the cavity 54 gradually tapers from a larger area toward the shaving surface 48 to a smaller area toward the distal end 56. The cavity may have approximately 100 mm at the distal end. 2 Approximately 300mm 2 Or more preferably about 125mm 2 Up to 175mm 2The area is designed to facilitate water flow and rinsing of the razor blade holder assembly 14. The distal end 56 may optionally have a plurality of grooves 58 and ridges 60. However, it should be understood that the distal end 56 may be generally flat. In some embodiments, the housing 42 of the razor blade holder assembly 14 may comprise a ferromagnetic material (e.g., a second surface 24). For example, the second surface 24 may be a ferromagnetic material portion of the housing 42 or a washer 55 (having a ferromagnetic property) mounted above the attachment 22 and attached to the flange 65 of the housing 42. The attachment 22 may extend from the flange 65 about 2.5 mm to about 5.5 mm to the distal end 56 to allow for full engagement. Figure 1 The rinsing chamber 22 is located within the rinsing chamber. For example, if the attachment 22 is too short, the razor blade holder assembly 14 may easily be knocked off the shank 12. The washer 55 may have a thickness of about 0.25 mm to about 0.6 mm. The washer 55 may have an inner diameter of about 10 mm to about 18 mm. The washer 55 may have an outer diameter of about 16 mm to about 24 mm. The size of the washer 55 can provide more efficient magnetic attachment within a limited area.

[0028] The washer 55 may provide a second surface 24 extending continuously around the attachment 22. Therefore, alignment may not be required compared to one or more ferrite magnetic elements with gaps between them. The second surface 24 (e.g., washer 55) may exhibit magnetic properties or combinations of magnetic properties. For example, the second surface 24 (e.g., washer 55) may include a permanent magnet, a dipole magnet, an electromagnet, a ferromagnetic material, a magnetized ferromagnetic material, a positive pole, a negative pole, or any combination thereof. The second surface 24 (e.g., washer 55) may, for example, be a magnetic element that applies an attractive magnetic force. The second surface 24 (e.g., washer 55) may, for example, be a magnetic element that is attracted by a magnetic force. The second surface 24 (e.g., washer 55) may be any suitable material exhibiting at least one of the previously mentioned magnetic properties. The second surface 24 (e.g., gasket 55) may, for example, comprise at least one of iron, nickel, aluminum, cobalt, boron, AlNiCo alloy, ferrite, gadolinium, dysprosium, samarium, samarium cobalt, neodymium iron boron, any alloy thereof, any ceramic thereof, or any combination thereof. Furthermore, the second surface 24 (e.g., gasket 55) may be plated or coated (e.g., with plastic, rubber, or nickel) to resist corrosion caused by shaving environments.

[0029] refer to Figure 2 and Figure 3The attachment 22 may have a plurality of circumferentially extending tabs 62 (e.g., undercut surfaces). For example, the attachment 22 may include three equally spaced tabs 62 for attachment of the washer 55. The tabs 62 may bend during assembly to secure the washer 55 to the attachment 22 (e.g., flange 65). The washer 55 may slide over the attachment 22 during assembly and then snap over the tabs 62 to lock the washer 55 in place. The washer 55 may be secured between the flange 65 and the plurality of tabs 62. In some embodiments, one or more crush ribs 64 may be provided on the attachment 22 to provide an interference fit between the washer 58 and the attachment 22. The crush ribs 64 facilitate preventing the washer 55 from rotating relative to the attachment 22 during use. One or more of the crush ribs 64 may be provided between adjacent tabs 62. The tabs 62 may be spaced approximately 100 to 140 degrees along the periphery of the attachment. The crushing protrusions 64 may have a depth of approximately 0.1 mm to approximately 0.5 mm to provide an interference fit between the washer 58 and the attachment 22.

[0030] refer to Figure 4 This illustrates roughly along Figure 3 A cross-sectional view of the razor blade holder assembly 14, taken from line 4-4. The flange 65 provides a flat surface for mounting the washer 55. The flange 65 may have a width “w1” of about 1.0 mm to about 4.0 mm to accommodate the washer 55. For example, the washer 55 may have approximately the same width as the flange 65. Crushing rib 64 ( Figure 2 This design allows for better accommodation of the accumulated tolerances between the inner diameter of the washer 55 and the outer diameter of the attachment 22. Therefore, gaps may exist between various portions of the washer 58 and the attachment 22, such as in areas without the crush rib 64. Figure 2 For example, during assembly, washer 55 reaches crush rib 64 ( Figure 2 Previously, it could slide freely above attachment 22. By pressing washer 55 against crushing rib 64 ( Figure 2 Above, washer 55 can fully abut against flange 65, thereby deforming crushing rib 64. Furthermore, during assembly, washer 55 can deflect tab 62 inward. Once washer 55 has slid past tab 62, tab 62 can bend back into place to secure washer 55 in the axial direction. Washer 55 can be caught between tab 62 and flange 65. It should be understood that washer 55 (and second surface 24) for magnetic attraction coupling interface 16 Figure 1 The housing 42 and / or flange 65 may be incorporated as part of the housing 42. For example, the housing 42 and / or flange 65 may contain a ferromagnetic material. In some embodiments, multiple magnetic elements may be positioned along flange 65.

[0031] The shaving surface 48 can be mounted to the gasket 68. In some embodiments, the shaving surface 48 can be directly mounted to the gasket 68, and the gasket 68 can be directly mounted to the housing 42. The gasket 68 can be a separate component (such as an O-ring) mounted to the housing 42, or the gasket 68 can be co-injected as part of the housing 42. The gasket 68 can contain an elastomeric material, such as silicone or various rubbers. A clamp 70 secures the shaving surface 48 to the housing 42. The shaving surface 48 can be positioned between the gasket 68 and the clamp 70. The gasket 68 can facilitate preloading the shaving surface 48 to the underside of the frame 70. The gasket 68 can also act as a shock absorber to provide protection during accidental product drops, thereby minimizing damage to the shaving surface 48 and / or the circular cutting edge 50. This may be particularly important, for example, if the shaving surface 48 and / or the circular cutting edge 50 are made of a brittle material, such as ceramic.

[0032] The clamp 70 may have a first end 72 mounted above a portion of the shaving surface 48 and a second end 74 pressed against an edge 76 of the housing 42 and angled toward the first end 72 to abut against a pad 68 preloaded onto the shaving surface 48. A flange 65 may be located on the housing 42 between the edge 76 and the attachment 22. In some embodiments, the edge 76 may extend circumferentially around the housing 42. Similarly, the second end 74 may also extend circumferentially around the edge 76 to reduce sharp edges and provide a stronger fit.

[0033] like Figure 4 As shown, the attachment 22 may have an inner diameter "D1" of about 10 mm to about 17 mm. The diameter "D1" allows for quick and easy flushing of the cavity 54 and the opening 52 communicating with the cavity 54. The inner diameter D1 may extend from the distal end 56 ( Figure 2 The attachment 22 tapers gradually from a smaller size towards a larger diameter toward the shaving surface 48. The attachment 22 may also have an outer diameter "D2" of approximately 12 mm to approximately 18 mm, measured at the washer 55 (e.g., the second surface 24). The outer diameter "D2" facilitates insertion of the attachment 22 into the flushing chamber 20 of the handle 12. Figure 1 ).

[0034] refer to Figure 5 Examples Figure 1A perspective view of the handle 12 of the shaving system 10. In some embodiments, a first surface 18 may be located at the proximal end 26 of the handle 12. The first surface 18 may define one or more recesses 78a, 78b, 78c, and 78d, the dimensions of which are designed to receive corresponding magnetic elements 80a, 80b, 80c, and 80d. The magnetic elements 80a, 80b, 80c, and 80d may have a diameter of about 1 mm to about 2 mm to provide sufficient magnetic force, but also fit within the area of ​​the first surface 18. The first surface 18 may be large enough to achieve sufficient magnetic attraction, but small enough to accommodate the shaving blade holder assembly 16 and the shaving system 10. Figure 1 This provides appropriate ergonomics while maximizing the size of the flushing chamber 20. For example, the first surface 18 may have a width “w2” of about 1.5 mm to about 4 mm to accommodate the recesses 78a, 78b, 78c, and 78d, as well as the magnetic elements 80a, 80b, 80c, and 80d, without weakening the handle 12. If the recesses 78a, 78b, 78c, and 78d are too large and / or the width of the first surface 18 is too small, the handle 12 may break or fracture upon its drop. In some embodiments, the first surface 18 may have a width of 100 mm. 2 Or a larger area. For example, the first surface 18 may have an area of ​​approximately 100 mm. 2 Approximately 300mm 2 or more preferably about 125mm 2 Up to 175mm 2The area is designed to allow for adequate reception of magnetic elements 80a, 80b, 80c, and 80d, as well as support for the razor blade holder assembly 14. It has been determined that the size of magnetic elements 80a, 80b, 80c, and 80d (and therefore recesses 78a, 78b, 78c, and 78d) can be minimized by aligning the polarities of the magnetic elements 80a, 80b, 80c, and 80d relative to each other to increase magnetic force. For example, two adjacent magnetic elements 80a and 80b may have opposite polarities. For example, magnetic element 80a may have its negative pole positioned on the first surface 18 of the shank 12, and magnetic element 80b may have its positive pole positioned on the first surface of the shank 12. The positive pole of magnetic element 80a may be positioned within recess 78a, and the negative pole of magnetic element 80b may be positioned within recess 78b. Similarly, two adjacent magnetic elements 80c and 80d may also have opposite polarities. For example, magnetic element 80c may have its positive pole positioned on the first surface 18 of the handle 12, and magnetic element 80d may have its negative pole positioned on the first surface of the handle 12. The positive pole of magnetic element 80d may be positioned within a recess 78d, and the negative pole of magnetic element 80c may be positioned within a recess 78c. Magnetic elements 80c and 80b may also have opposite polarities, and magnetic elements 80d and 80a may also have opposite polarities. This orientation and polarity of the magnetic elements results in the generation of a stronger magnetic force, thereby reducing the size of the required magnetic elements. Although four magnetic elements 80a, 80b, 80c, and 80d are shown, it should be understood that more magnetic elements may be added if a greater attractive force is required. For example, six or more magnetic elements may be placed along the first surface 18 to provide even greater magnetic force.

[0035] refer to Figure 6 and Figure 7 The perspective view of the shaving system 10 and its approximate direction are shown respectively. Figure 6 A cross-sectional view of the shaving system 10 taken by line 7-7. In some embodiments, the diameter D3 of the razor blade holder assembly 14 may be approximately (e.g., within 10% to 15%) the diameter D4 of the first end 26 (e.g., the first surface 18) of the handle 12. If the razor blade holder assembly 14 extends too far above the proximal end 26 of the handle 12, the user may accidentally knock or remove the razor blade holder assembly 14 from the handle 12. In some embodiments, the outer wall 82 of the attachment 22 may be spaced apart from the inner wall 84 defining the flushing chamber 20 to provide a gap 86 between the attachment 22 and the handle 12. Thus, the attachment 22 may fit within the flushing chamber 20 without mechanically engaging with the inner wall 84 to allow easy insertion and removal of the razor blade holder assembly 14. However, it should be understood that the inner wall 84 may provide support and contact with the attachment 22 during use, as the razor blade holder assembly 14 may move slightly.

[0036] refer to Figure 8 The image shows a bottom view of an alternative embodiment of the razor blade holder assembly 100. Figure 8 The razor blade holder assembly 100 can be used with Figures 1 to 7 The razor blade holder assembly 14 is essentially the same, differing only in the improved clamp 102 and housing 104. The clamp 102 may have multiple tabs 106, 108, 110, 112, 114, and 116 to secure the shaving surface 48 to the housing 104. The tabs 106, 108, 110, 112, 114, and 116 provide secure attachment of the shaving surface 48 to the housing 104 without adversely affecting the aesthetics of the smooth, rounded outer surface 118 of the clamp 102. Single crimp type design (such as...) Figures 1 to 7 The fixture 70 may cause wrinkles on the outer surface of the fixture 70.

[0037] refer to Figure 9 It shows roughly along Figure 8 A cross-sectional view taken along line 9-9. The clamp 102 can be mounted above a portion of the shaving surface 48. Therefore, the shaving surface 48 can be positioned between the clamp 102 and the housing 104. Protrusions 106, 108, 110, 112, 114, and 116 ( Figure 9 The tabs 106 and 112 shown can be pressed against the corresponding lower surfaces 120 and 122 of the housing 104. The lower surfaces 120 and 122 can extend outward toward the outer surface 118 of the clamp 102 and downward and away from the shaving surface 48 to facilitate a more secure pressing of the tabs 106, 108, 110, 112, 114 and 116 against the housing 104.

[0038] refer to Figure 10 A perspective view of the handle 12 is illustrated. In some embodiments, a first surface 18 of the handle 12 may extend along a first plane P1. The central axis A1 of the handle 12 and the first plane P1 may define an angle of less than 90 degrees (e.g., about 30 degrees to about 80 degrees). The inclination of the first surface 18 relative to the central axis A1 of the handle 12 not only provides a more optimized angle for the consumer to hold the shaving system 10 ( Figure 1 ) is held against the skin surface (e.g., face and neck), and can also hold the razor blade holder assembly 12 ( Figure 1When attached to the handle 14, it provides improved visibility. In some embodiments, the central axis A1 of the handle 12 may be substantially aligned with the rinse chamber 20 (e.g., the central axis of the rinse chamber may be substantially aligned with the central axis A1 of the handle 12, which provides greater precision and control of the handle 12, especially around the mouth and nose area of ​​the face). In some embodiments, less pressure may be required during shaving, especially when shaving fine, short hairs. Female users' skin may be more sensitive to shaving pressure because they do not shave as frequently as men, so greater control over the pressure applied to the handle 12 may be important.

[0039] While shaving systems have been described above, it should be noted that the magnetic and / or mechanical couplings described herein can be used in any suitable consumer product system, including but not limited to consumer products, personal hygiene products (e.g., toothbrushes or hairbrushes), reusable shaving systems, interchangeable hair removal systems, and grooming systems. It should also be understood that... Figure 1 The shaving system 10 shown is for illustrative purposes only, and any other shaving system, hair removal system, or subsystem may be used in conjunction with or in place of this system. A preferred shaving system is a safety razor with a replaceable blade holder design.

[0040] 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 stated value and a range of functionally equivalent values ​​around that value. For example, a dimension disclosed as “40 mm” is intended to represent “about 40 mm”. Furthermore, dimensions should not be maintained to an impossibly high standard of metaphysical identity, which does not account for differences arising from typical manufacturing tolerances. Therefore, the term “about” should be understood as being within the range of typical manufacturing and measurement tolerances.
