    [0001] [001] The present invention relates to shaving or shaving cartridges and apparatus and, more particularly, to shaving or shaving cartridges that provide safe and simple attachment and disengagement to a handle. BACKGROUND OF THE INVENTION
    [0002] [002] Recently, razors or shavers with numerous blades have been proposed in the literature and marketed, for example, US patent publication No. 2005/0039337 A1 published on February 24, 2005, which generally describes a type model that has been marketed globally as the FusionTM five-blade razor or razor by Gillette Company.
    [0003] [003] In emerging markets, such as China and India, the razor or shaver of choice is a standard double-edged razor or shaver, for example, in US Patent No. 3,274,683 issued on September 27 of 1966, which generally describes a model used in emerging markets. The standard double-edged razor or shaver can be economical, but the user tends to experience scratches, cuts and irritation. Most emerging market consumers do not have the means to purchase the razors or shavers that are widely popular in the United States. Some commercially available razors or shavers have pivot mechanisms that include a handle with a pin that fits into a pocket located on a cartridge. These pivot mechanisms do not provide optimal rinsing and often block water from reaching the blades.
    [0004] [004] Shaving or waxing consumers in emerging markets do shaving or waxing infrequently, sometimes just once or twice a week. There is also little or no availability of running water to rinse or clean a razor or shave, and the availability of skin cleansing creams and pre-shave or epilation and post-shave or epilation aids is limited. Pre-shaving or waxing aids may include shaving or waxing oils, gels and lotions, and after-shaving or waxing aids may include aftershave gels, lotions and humectants. A mug or bowl is typically filled with water and is used to rinse the razor or shave because running water is scarce. It is much more difficult to rinse a razor or shave in a mug or bowl compared to running water. The razors or shavers featured in the patent application mentioned above are quite sophisticated, having been developed for Western waxing habits, practices and environments, and therefore do not provide an ideal shaving or waxing experience for consumers in emerging markets. Shaving or waxing consumers in emerging countries have a very different shaving or waxing environment, as well as different shaving or waxing habits and practices, than shaving or waxing consumers in more developed countries, such as the United States. Shaving or waxing consumers in emerging countries want the benefits of various shaving or waxing technologies that provide a closer and more comfortable shaving or waxing, but are not willing to sacrifice the cost or rinse of the shaving or waxing cartridge. SUMMARY OF THE INVENTION
    [0005] [005] In one aspect, the invention features, in general, a razor or shaver with a housing sized to receive at least one blade. The housing has a pair of opposing parallel walls apart, each defining a completely closed opening that extends completely through the respective walls.
    [0006] [006] In another aspect, the invention generally presents a cable that has a body and a neck that extends from the body that has an inner surface and an outer surface. The neck has a pair of opposing flexible arms that taper outward to define a tapered slit and a pin member that extends outwardly from each of the respective arms. The pin members are movable from a first position to a second position. The pin members are closer to each other in the second position than in the first position.
    [0007] [007] In another aspect, the invention generally presents a razor or shaving apparatus with a housing that has a first wall that defines a first fully closed opening that extends through it and a second wall that defines a second opening fully closed that extends through it. A cable is attached to the housing in the first position and disengaged from the housing in a second position. The cable has a first arm with a pin member and a support member, each extending outwardly from the first arm, and a second arm with a pin member and a support member, each of which extends outward from the second arm. In the first position, the pin member of the first arm is positioned inside the first opening and the pin member of the second arm is positioned inside the second opening to define a rinse gap between the blade and the pin members.

    [0016] [016] The consumer needs of emerging markets require economical and intuitive shavers or shavers that include modern advantages, such as replaceable shaving or shaving cartridges that follow the contours of the face during shaving or waxing and do not intentionally disengage from the handle. When the shaving or shaving cartridge must be replaced, the shaving or shaving cartridge should be able to be removed from the handle in a simple and intuitive manner.
    [0017] [017] With reference to figure 1, a possible embodiment of the present invention is shown illustrating a shaving or shaving device 10 that has a shaving or shaving cartridge 11 mounted on a shaving or shaving handle 14 that has a body 26 and a neck 28. The body 26 of the handle 14 can provide an area for the user to comfortably grip the razor or shave 10. The neck 28 can have a geometry of the shape, in general, "V" that extends from body 26. As will be explained in more detail below, the shaving or shaving cartridge 11 can be pivotally engaged (that is, the rotation of the cartridge 11 around a geometric axis in relation to the razor handle or shave 14) and / or removable with a razor or shave handle 14. The shaving or shaving cartridge 11 can include a housing 12 sized to receive at least one blade 16. The housing 12 can have a guard 18 in front of the blade 16 and a cover 20 behind blade 16. Housing 12 may have a top surface 22 extending from guard 18 to cover 20. In certain embodiments, top surface 22 may define an arc 24 with a radius of about 2 mm, 3 mm, or 4 mm to about 6 mm, 8 mm, or 10 mm. The shaver or shaver 10 may not have a return mechanism, such as a spring plunger that tilts the housing 12 into a predetermined pivot position in relation to the shaver or shaver handle 14. The lack of a shaving mechanism return allows the arched top surface 22 to facilitate the proper positioning of the housing 12 against the skin surface during a shaving or waxing course. The housing 12 can rotate freely in relation to the razor or shaving handle 14 (for example, with little or no force except friction) as the top surface 22 of the housing 12 slides across the skin surface during a shaving or waxing course to give the user more control of the shaving or shaving cartridge 11. Return mechanisms have a tendency to fatigue and / or break with repeated use, which negatively influences shaving or hair removal performance (eg proximity and comfort) . The lack of a return mechanism can also decrease the complexity and costs of shaving or shaving 10 and improve rinseability by removing obstructions near the blade 16. The return mechanisms can also obstruct the passage of water to the blades, especially if the cartridge is rinsed in a mug or bowl of water instead of running water.
    [0018] [018] With reference to figure 2, a top view of the shaving or shaving cartridge 11 is shown. The housing 12 of the shaving or shaving cartridge 11 can be injection molded from a semi-rigid polymeric material. In certain embodiments, housing 12 can be molded from Noryl ™ (a blend of polyphenylene oxide (PPO) and polystyrene developed by General Electric Plastics, now SABIC Innovative Plastics). Housing 12 may be molded from other semi-rigid polymers that have a Shore A hardness of approximately 60 to 140, including, but not limited to, acetal, polypropylene, high impact polystyrene, or any combination thereof. Although only one blade 16 is shown, housing 12 can have two or more blades 16. Blades 16 can be mounted to the housing and secured by staking, ultrasonic welding, insert element molding, wire wrap, or any other assembly process known to those skilled in the art.
    [0019] [019] The bulkhead 18 may have a plurality of fingers 30 extending transversely to the blade 16. In certain embodiments, the fingers 30 may have a top surface 32 which defines the arch 24 of the top surface 22 (see figure 1 ) of the housing 12. The lid 20 may also have a top surface 34 that defines the arch 24 of the top surface 22 of the housing 12. In certain embodiments, the lid 20 may have an elongated band 36 that contains a shaving aid or epilation to provide lubrication to the skin surface during shaving or epilation. The housing 12 may have a pair of parallel parallel walls 40 and 42 that are transversal to the blade 16. The walls 40 and 42 can each define a fully enclosed opening 44 and 46 that extends completely through the respective walls 40 and 42 Fenced openings 44 and 46 can facilitate proper engagement of housing 12 with the razor or shaving handle 14 (not shown). Although walls 40 and 42 are shown as side walls located at opposite end ends of housing 12, walls 40 and 42 can be any wall of housing 12, as an interior wall. Walls 40 and 42 can be positioned at opposite termination ends of housing 12 to provide a more open space between walls 40 and 42 for an improved rinse of blade 16. For example, water can access blade 16 from no only from the top and / or bottom of the housing 12, but from the side of the housing 12 (i.e., through the openings 44 and 46 in the walls 40 and 42).
    [0020] [020] Referring to figure 3, an assembly view of the razor 10 is shown with the razor or epilator cartridge 11 separated from the razor or epilator handle 14. The walls 40 and 42 of the housing 12 can be moved apart by a distance d1 to receive the razor or epilating handle 14 in a releasable latch, as will be discussed in more detail below. In certain embodiments, the distance d1 can be about 10 mm, 20 mm, or 30 mm to about 35 mm, 40 mm, or 45 mm. Neck 28 may have a pair of opposite arms 50 and 52 that taper outward. The pair of opposing arms 50 and 52 can define a tapered slit 55 that extends to the neck 28 of the razor or shaving handle 14, so that the arms 50 and 52 taper closer to a base 57 of the tapered slot 55 where the arms 50 and 52 meet. Each arm has an end portion 54 and 56 with a pin member 60 and 62 extending outwardly from each of the respective end portions 54 and 56. As will be explained in more detail below, the tapered slot 55 can allow a small change in the distance between the arms 50 and 52 on the neck 28 to result in a much greater change in the distance between the pin members 60 and 62.
    [0021] [021] A user can engage and disengage the shaving or shaving cartridge 11 from the shaver or shaving handle 14 by tightening arms 50 and 52 (for example, neck 28) and pulling the shaving or shaving cartridge 11 and the razor or epilator handle 14 in opposite directions. The tapered slot 55 can provide the arms 50 and 52 with adequate flexibility and strength so that the razor or shaving handle 14 can be repeatedly engaged and disengaged with the shaving or shaving cartridge 11 without the arms 50 and 52 suffering fatigue or rupture. In certain embodiments, a axis of rotation 64 can extend through the center of the pin members 60 and 62. The openings 44 and 46 of the housing 12 can be dimensioned to receive the respective pin members 60 and 62 to facilitate movement (i.e. , rotation) of the shaving or shaving cartridge 11 around the axis of rotation 64.
    [0022] [022] A pair of support elements 66 and 68 can extend outwardly from the respective end portions 54 and 56. The pair of support elements 66 and 68 can facilitate the movement of the shaving or shaving cartridge 11 around axis of rotation 64 and can prevent unintentional disengagement of the shaving or shaving cartridge 11 from the shaving or shaving handle 14. The pin members 60 and 62 can be parallel to and away from the respective support element 66 and 68 to facilitate engagement with the respective walls 42 and 40. In certain embodiments, the support elements 66 and 68 and the pin members 60 and 62 can be perpendicular to the respective walls 40 and 42. The support elements 66 and 68 can act as load-bearing structures, so that forces can be transmitted to end portions 54 and 56, as well as to arms 50 and 52, thereby relieving tension on the smaller pin members 60 and 62 to avoid the break or f of pin members 60 and 62.
    [0023] [023] The arms 50 and 52 may have a first position to provide the appropriate engagement of the razor or epilating cartridge 11 to the razor or epilating handle 14 and a second position to provide the appropriate disengagement of the razor or epilating cartridge from the razor or shaving cord 14. In the first position, the pin members 60 and 62 can be arranged inside the respective openings 46 and 44. With additional reference to figure 4, the pin members 60 and 62 can be separated by a "d2" distance. In the first position, the distance "d2" can be greater than the distance "d1" (figure 3) by the length of the pin members 60 and 62 to provide the appropriate engagement of the pin members 60 and 62 within the respective openings 46 and 44. For example, if d1 is 40 mm and the length of each of the pin members 60 and 62 is 2 mm, then d2 can be 44 mm from the first portion d2. The engagement of the razor or shaving handle 14 to the shaving or shaving cartridge 11 is improved by extending the openings 44 and 46 completely through the respective walls 40 and 42. The openings 44 and 46 allow the length of the pin members be increased for a more robust hitch under both variations in dimensional tolerance and in use. For example, dimensional variations can cause a pin to reach the bottom prematurely in a pocket or blind hole, so the total length of the pin is not used for optimal engagement. The openings 44 and 46 which extend completely through the walls 40 and 42 can facilitate the pin members 60 and 62 which are completely positioned within the respective openings 46 and 44 for optimum engagement. In certain embodiments, pin members 60 and 62 can extend about 1 mm, 1.5 mm, or 2 mm to about 3 mm, 4 mm, or 5 mm from each respective end portion 54 and 56 of arms 50 and 52. Since openings 46 and 44 do not limit the length of pin members 60 and 62, pin members 60 and 62 can extend through openings 44 and 46 and beyond housing 12. In certain embodiments , the end portions 54 and 56 of the respective arms 50 and 52 can apply an outward force against the respective walls 40 and 42 for an increased engagement of the cartridge 11 with the razor or epilator handle 14.
    [0024] [024] A user can disengage the razor or shave handle 14 from the shaving cartridge or shave 11 by squeezing arms 50 and 52 together to decrease d2, resulting in the second position. Pin members 60 and 62 may be closer together in the second position than in the first position. For example, in the second position, d2 can be less than d1, so that cartridge 11 can be pulled away from the razor or epilator handle 14 with little or no force. Once the cartridge 11 is detached from the razor or epilator handle 14, the force applied to the razor or epilator handle 14 can be removed, resulting in the pin members 60 and 62 returning to the first position. In the first position, arms 50 and 52 can be fully extended (for example, arms 50 and 52 are not flexed because no external force is being applied to the cable).
    [0025] [025] A user can re-engage the razor or epilator handle 14 to the razor or epilate cartridge 11 by tightening arms 50 and 52, resulting in the second position, which allows pin members 60 and 62 to be inserted between walls 42 and 40. The force applied to arms 50 and 52 can then be released to allow pin members 60 and 62 to fit into respective openings 46 and 44. Openings 44 and 46 can extend completely through of walls 40 and 42 to facilitate visual indication that the shaving or shaving cartridge 11 is properly engaged with the shaving or shaving handle 14. For example, pin members 60 and 62 and walls 40 and 42 of the housing 12 may be of contrasting colors, to allow a user to quickly determine whether pin members 60 and 62 are properly positioned within openings 46 and 44.
    [0026] [026] The shaving or shaving handle 14 can be molded from polymeric material to facilitate the inward movement (for example, flexing) of the arms 50 and 52. The shaving or shaving handle 14 can be a one-piece molded construction to improve simplicity and reduce costs (for example, the body 26, the neck 28, the pair of opposing arms 50 and 52 and the pin members 60 and 62 are integral). The shaving or shaving handle 14 can be injection molded from a polymeric material that provides adequate strength and flexibility to allow repeated movement of the arms 50 and 52. The shaving or shaving handle 14 can be shaped by injection from semi-rigid polymeric materials, such as NorylTM (a mixture of polyphenylene oxide (PPO) and polystyrene developed by General Electric Plastics, now SABIC Innovative Plastics). The razor or shaving handle 14 can be molded from other semi-rigid polymers that have a Shore A hardness of approximately 60 to 140, including, but not limited to, acetal, polypropylene, high impact polystyrene (HIPS), acrylonitrile-butadiene-styrene (for example, Terluran® GP-22, BASF, The Chemical Company), or any combination thereof. Other materials or mechanisms can also be used to move the arms 50 and 52.
    [0027] [027] Pin members 60 and 62 may not necessarily return to the same third position after each disengagement of cartridge 11 from the razor or shaving cord 14 because of permanent deformation of the razor or shaving cord 14. For example, d2 in the third position may be lower with each successive disengagement of the cartridge 11 from the razor or shaving handle 14. In certain embodiments, the arms 50 and 52 may have an internal surface 70 that defines the slot 50. embodiments, the inner surface 70 may have a pair of opposing protrusions 72 and 74 apart. The pair of protrusions 72 and 74 may act as a pair of retaining surfaces to limit the deflection of the arms 50 and 52 during engagement and disengagement of the cartridge shaving or shaving 11 with the razor or shaving handle 14. The protrusions 72 and 74 can prevent premature failure or fatigue of the arms 50 and 52 by limiting the distance of the arms 50 and 52 are displaced. If the travel of arms 50 and 52 is not limited, flexion of arms 50 and 52 can result in stress levels that are greater than the cable material resistance limit 14. If the material resistance limit is exceeded, the permanent deformation of the razor or shaving handle may result. Permanent deformation can cause the cartridge 11 to engage the razor or shave handle 14 in each successive deflection of the arms 50 and 52, which may result in inadvertent disengagement of the cartridge 11 from the razor or shave handle 14. In certain embodiments, an adequate flexural strength of the material for the razor or shaving handle 14 to minimize permanent deformation can be about 35 MPa, 40 MPa, or 45 MPa to about 65 MPa, 75 MPa, or 85 MPa (ASTM D-790 at 23 ° C). Materials with adequate flexural strength are provided above. In certain embodiments, protrusions 72 and 74 can be separated by a distance "d3" of about 0.2 mm, 0.4 mm, or 0.6 mm to about 1.5 mm, 2.5 mm, or 3.5 mm to minimize permanent deformation or breakage of arms 50 and 52.
    [0028] [028] The tapered slit 55 can allow for a small change in the distance between arms 50 and 52 on the neck 28 to result in a much greater change in the distance between pin members 60 and 62. For example, arms 50 and 52 can be pressed from the first position to the second position so that the protrusions 72 and 74 travel about 1 mm before they come into contact with each other. Even though protuberances 72 and 74 travel only about 1 mm before coming into contact with each other, the change in d2 from the first position to the second position can be about 2 mm. In certain embodiments, the change in d2 from the first position to the second position can be about 50%, 75%, or 100% to about 150%, 200%, or 300% greater than the corresponding change in d3 .
    [0029] [029] In certain embodiments, the neck 28 of the razor or shaving cord 14 may have an outer surface 75 with one or more digital plates 76 and 78 to indicate the appropriate place to tighten the razor or shaving cord 14 to engage and disengage the shaving or shaving cartridge 11 with the shaver or shaving handle 14. Digital plates 76 and 78 can have a plurality of protuberances 80 and 82 to improve the user's grip when the arms 50 and 52 are tight together. Digital cards 76 and 78 can be particularly advantageous when a user has to squeeze arms 50 and 52 together in a wet environment. Other embodiments may include digital plates 76 and 78 with a smooth concave surface. Digital plates 76 and 78 can be molded from the same material as the razor or epilator handle 14 or can be molded from a softer material to provide cushioning for a more comfortable grip (for example, digital plates 76 and 78 can be molded from a polymeric material that has a Shore A hardness of about 20, 30, or 40 to about 50, 60, or 70).
    [0030] [030] With reference to figure 5, a partial right side view of the razor 10 is shown with the arm 50 of the razor or epilator handle 14 attached to the wall 42 of the housing. For the sake of clarity and brevity, only the wall 42 of the housing 12 and the arm 50 of the razor or shaver handle 14 will be described in detail, as it is understood that the right side view of the razor or shaver 10 is an image in mirror of the left side view of the shaver or shaver 10. The characteristics of the wall 42 of the housing 12 and the arm 50 of the shaver or hair removal handle 14 can be called complementary characteristics of the wall 40 of the housing 12 and arm 52 of the razor or shaving handle 14. The pin member 60 can be positioned inside the opening 46 of the wall 42. In certain embodiments, the pin member 60 can have a diameter of about 1.5 mm, 2, 0 mm, or 3.0 mm to about 3.5 mm, 4.0 mm or 4.5 mm. The diameter of the pin member 60 may be smaller than the opening 46 to provide a rinse gap 27 between the blade 16 and the pin member 60 to allow water to access the blade 16. In certain embodiments, the rinse gap 27 it can be about 0.10 mm, 0.125 mm, or 0.15 mm to about 0.3 mm, 0.4 mm, or 0.5 mm. The wall 42 may have a pair of opposing supporting surfaces 90 and 92 that define a pair of concentric arcs 94 and 96 (represented by dotted lines). The support surface 90 can define a "U" shaped slot 95 which communicates with the opening 46 to facilitate the removal of shaving debris or epilation of the blade 16 during rinsing. As shown in figure 5, the blade 16 can be accessed by the water from the sides of the housing 12 for an improved rinse.
    [0031] [031] A plane 98 can intersect the geometric axis of rotation 64 and extend through the center of concentric arcs 94 and 96. The plane 98 can also extend through the center of the top surface 22 of housing 12 to facilitate the balance of the shaving or shaving cartridge 11. Plan 98 can be about 0%, 2%, or 4% to about 6%, 8%, or 10% of the center of the top surface 22 of the housing 12. For For example, if the plane 98 is at 0% of the middle of the top surface 22 of the housing, the plane 98 bisects the top surface 22 in half, resulting in the balance of the shaving or shaving cartridge 11 around the axis of rotation 64. The arched top surface 22 of the housing 12 and the balance of the housing 12 allows the shaving or shaving cartridge 11 to rotate to the appropriate position against the skin surface without the use of force, or with the application of a small amount strength to provide a more comfortable shave or epilation l. In certain embodiments, a edge 25 of the blade 16 can also be positioned on the 98 plane.
    [0032] [032] The wall 42 of the housing 12 can be slidably engaged between the pin member 60 and the support element 66 to reduce the ancillary movements of the shaving or shaving cartridge 11. The pin member 60 and the support element 66 may limit the movement of the shaving or shaving cartridge 11 to rotation around the axis of rotation 64 to provide smooth rotational movement of the shaving or shaving cartridge 11 with respect to the shaver or shaving handle 14. The support 90 can slidably engage pin member 60, and support surface 92 can slidably engage support member 66. Support element 66 can contact support surface 92 to prevent the member pin 60 travel axially and contact the blade 16, which can damage the blade 16. The pin member 60 is not limited to completely circular or symmetrical cross sections, for example, the cross section salt of pin member 60 can be truncated resulting in the shape of semi-circular cross section. The pin member 60 can have various semi-circular shapes to allow the size of the rinse gap 27 to be increased to improve the cleanliness of the blades 16. A semi-circular cross-section shape can facilitate proper sliding of the pin member 60 against the support surface 94 during the desired amount of rotation of the shaving or shaving cartridge 11. In certain embodiments, the shaving or shaving cartridge 11 can move around the geometric axis of rotation by a total of about 10 degrees, 15 degrees, or 20 degrees to about 30 degrees, 40 degrees or 50 degrees. A semi-circular cross-section shape can facilitate the positioning of the pin member 60 closest to the blade 16 (without coming into contact with the blade 16), which results in the positioning of the axis of rotation 64 closest to the blade 16 for a improved control of the shaving or shaving cartridge 11 during shaving or waxing.
    [0033] [033] Referring to figure 6, a bottom view of an alternative embodiment of a shaving or shaving cartridge 111 having a housing 112 is shown. The shaving or shaving cartridge 111 and the housing 112 can be substantially the same as the shaving cartridge shaving or shaving 11 and the housing 12 previously described, however, the housing 112 may have a pair of internal walls 140 and 142 that define a pair of openings 144 and 146 completely surrounded by the walls and extending completely through the walls 140 and 142. Openings 144 and 146 can be sized to receive pin members, such as pin members 60 and 62 described above. The pair of spaced walls 140 and 142 can be positioned between a pair of end walls 102 and 104 of the housing 112. Each of the walls 140 and 142 can be arranged between one of the pin members 60 and 62 and one of the support elements 66 and 68 for proper engagement and rotation of the shaving or shaving cartridge 111 in relation to a handle, such as the shaving or shaving handle 14 (as previously described).
    [0034] [034] Referring to figures 7A and 7B, another possible embodiment of a razor or epilator 200 is shown. Figure 7A shows a right side view of the razor or epilator 200 that has a razor or epilator cartridge 211 with a housing 212 attached to a handle 214. Figure 7B is a partial bottom cross-sectional view of the razor or shaver 200 taken, generally, along line 7-7 of figure 7A. The razor or shaving cord 214 may be similar to the razor or shaving cord 214 as previously described, for example, housing 212 may have a wall 242 that defines an opening 242 fully surrounded by the wall extending through the the razor or shaver handle 214 may have a pin member 260 and a support member 266 that engages the housing 212. For clarity and brevity, only one side of the razor or epilator 200 is shown. The housing 212, the support element 266, and the pin member 260 will be described in detail, as it is understood that the right side view of the razor 200 is a mirror image of the left side view of the razor or shave 200. The shaver or shave 200 can be substantially the same as the shaver or shave 10, as previously shown and described, however, the pin member 260 can taper out towards the support element 266. The tapered pin member 260 can provide an improved engagement with housing 212. Housing 212 may have a wall 240 with a corresponding tapered surface 241 to further improve the engagement of the razor or shaving handle 214 to housing 212. The member tapered pin 260 and opening 246 can still provide a rinse gap 227 between pin member 260 and a blade 216.
