Definitions
- the present invention relates to shaving razors and more particularly to shaving razor cartridges having docking mechanisms that removably and/or pivotably couple a shaving razor handle to a shaving cartridge.
- the shaving razor of choice is a standard double edge style razor, e.g., in United States Patent 3,274,683 issued September 27, 1966 , generally describes a typical design used in emerging markets. Consumers in these markets typically do not have the means to purchase the shaving razors that are widely popular in the United States.
- the standard double edge style razor designs may be economical, but they do not offer the benefits of the designs typically used in more industrial countries.
- Shaving consumers in emerging markets typically shave infrequently, sometimes only once or twice a week. There is also little or no availability of running water to rinse or clean a shaving razor and the availability of skin cleansers and pre-shaving and post-shaving shaving aids are limited.
- Pre-shaving aids may include shaving oils, gels and lotions and post-shaving aids may include after shave gels, lotions and moisturizers.
- a cup or bowl is typically filled with water and is used to rinse the shaving razor.
- the shaving razors disclosed in the above mentioned patent application are quite sophisticated having have been designed for Western shaving habits, practices and environments, and thus do not deliver an ideal shaving experience for consumers in emerging markets.
- the shaving consumer in emerging countries have a much different shaving environment as well as different shaving habits and practices than the typical shaving consumer in more developed countries, such as the United States. Even if a less sophisticated version of the popular five bladed FusionTM shaving razor was available for these consumers, it would still not provide the optimal shaving experience because of their unique shaving environment, habits, practices and shaving environment.
- the invention features, in general, a shaving razor according to claim 1 for wet shaving including a handle, a cartridge and an interconnect member.
- the handle includes a distal gripping portion and an integral proximal end portion.
- the cartridge has at least one blade for shaving and is pivotably joined to the interconnect member.
- the interconnect member is detachably mounted to the integral proximal end portion of the handle.
- a shaving razor 10 having a handle 12 and a cartridge 14 having at least one blade 11 for shaving.
- the handle 12 may have a distal gripping portion 24 and a proximal end portion 26.
- the cartridge 14 may be detachably and pivotably mounted to the handle 12.
- the cartridge 14 may be detachably and fixedly mounted to the handle 12.
- the cartridge 14 may be removed from the handle 12 and replaced with a new cartridge 14 as needed by a user.
- An interconnect member 16 may detachably join the cartridge 14 to the proximal end portion 26 of the handle 12.
- the proximal end portion 26 that mounts to the interconnect member 16 may be of an integral, one piece construction which may be molded and/or ultrasonic welded together to form a single component.
- the proximal end portion 26 that is operatively connected to the interconnect member 16 may not have any moving parts.
- integrated unless specified otherwise, is defined as being deficient of or lacking any moving components. Moving components are more prone to failure or breaking and may interfere with the proper function of the handle 12 and the interconnect member 16. Cost is also a significant factor in the purchasing decision of consumers in emerging markets. Many shaving razors offer detachable cartridges that pivot, however these designs often require numerous components which increase the complexity and cost of the shaving razor.
- Detachment mechanisms with numerous moving parts can also trap water, shaving aids and debris, which may interfere with or corrode various components of the detachment mechanism, such as springs.
- the detachment mechanism may also be difficult clean and wash out, which may lead to the growth of microorganisms.
- the interconnect member 16 may be permanently and pivotably joined to the cartridge 14, which may provide several advantages.
- the interconnect member 16, rather than the handle 12, may have moving components which can fatigue and fail with prolonged use, which happens with all shaving razors with attachment mechanisms. Since the cartridge 14 is replaced when the blade 11 become dull, the cartridge 14 and thus the interconnect member 16 are replaced before the interconnect member 16 is exposed to a number of fatigue cycles which may result in failure of the connection between the cartridge 14 and the handle 12. By having the moving components that are susceptible to wear or breakage located on the cartridge 14 (for example, the interconnect member 16) the user may never need to purchase a replacement handle 12.
- a custom handle 12 with no moving components is that after market handle manufactures' are more likely to manufacture custom replacement handles, since the complexity of the handle is greatly reduced and little or no additional assembly work is necessary.
- a custom handle can be molded, machined or cast using high end materials, such a chrome and various precious metals or plating, for a fraction of the cost of a custom handle requiring various connection mechanisms with moving and/or fragile components.
- the interconnect member 16 may provide for single point docking of the handle 12 to the cartridge 14. Single point docking requires only a single area for connection, for example, one area or component on the handle 12 and one component or area on the interconnect member 16. Single point docking simplifies the attachment and detachment of the handle 12 from the cartridge 14 because multiple areas or components on the handle 12 and multiple areas or components on the cartridge 14 do not need to all accurately align and engage for proper attachment and detachment. As will be described in greater detail below, the interconnect member 16 may be provided with a release tab 22 to facilitate the disengagement of the cartridge 14 from the handle 12.
- the release tab 22 may allow the user to remove the cartridge 14 from the handle 12 with a single digit and/or a single action without the complexity or extra components such as an ejector or release button, which typically requires a spring plus additional components.
- the release tab 22 may eject or project the interconnect member 16 and cartridge 14 from the handle 12. The ability of the release tab 22 to eject or project the cartridge from the handle allows the user to remove and dispose of the cartridge 14 with a single hand.
- the interconnect member 16 may have a pair of arms 18 and 20 that securely and pivotably connect to the cartridge 14.
- the opposing arms 18 and 20 may be relatively long and with a smaller wall thickness, and thus may be more prone to fatigue or failure. By locating the arms 18 and 20 on the cartridge 14 (which is disposed after a limited number of uses) the handle 12 may never need to be replaced due to components failing.
- the opposing arms 18 and 20 may allow for an open space or window below the cartridge 14, which may improve the ability for water to rinse out the cartridge 14 after shaving.
- the interconnect member 16 may be a single integral component which is capable of detachably and pivotably coupling the cartridge 14 to the handle 12, without the need of separate components assembled to the handle 12 or the cartridge 14.
- the handle 12, the cartridge 14 and the interconnect member 16 may be molded from polymers such as high impact polystyrene (HIPS), but other semi-rigid polymers such as polypropylene (PP) and acrylonitrile butadiene styrene (ABS) may also be used.
- the handle 12 may be composed of more durable materials such as metals, composites, more rigid plastics or any combination thereof.
- the handle 12 may include a distal gripping portion 24 and a proximal end portion 26.
- the proximal end portion 26 of the handle 12 may be of generally solid construction.
- a generally solid proximal end portion 26 may have no moving components or features such as, apertures or holes, which may trap shaving aids or debris. Trapped shaving aids or debris may adversely affect the proper function of a release mechanism, making it difficult to eject a razor cartridge from a handle.
- the proximal end portion 26 may include a protrusion 28 with an enlarged latch member 30 having a tapered leading end portion 32 and a tapered trailing end portion 34.
- the tapered trailing end portion 34 of the enlarged latch member 30 may be spaced apart from a front wall 36 of the proximal end portion 26 of the handle 12.
- the interconnect member 16 may include a housing 38 having a latch 40 with a free end 42 that engages the protrusion 28.
- a tab member 22 having a first position and a second position may extend from the free end 42.
- a tab member 22 is shown, other release mechanisms such as buttons, knobs, pins, levers or dials may be used.
- the housing 38 may define an opening 45 dimensioned to receive the protrusion 28 of the handle 12.
- the tapered leading end portion 32 may aid in guiding and inserting the protrusion 28 into the housing 38.
- FIG. 3 an enlarged perspective view of the cartridge 14 and the proximal end portion 26 of the handle 12 is illustrated.
- the proximal end portion 26 of the handle 12 may allow for a "one way” with the interconnect member 16, thus the cartridge 14 is prevented from being attached incorrectly (for example, upside down).
- One way loading creates a predetermined loading configuration, thus the user can not incorrectly attach the handle 12 to the cartridge 14.
- the "one way” loading of the cartridge 14 may be facilitated by housing 38 and/or the proximal end portion 26 of the handle 12 having an asymmetrical geometry.
- cartridges have a tendency to disengage from a handle if the user does not assemble them properly, which may result in injury to the user during shaving.
- the housing 38 may include the latch 40, a first wall 44 and a pair of side walls 60 and 62 that define an opening 45. Although the latch 40 is shown with a pair of slits 41 and 43, slits 41 and 43 are not required for the function of latch 40.
- the housing 38 may include a first wall 44 having a tapered guide member 46 which may aid in the alignment and securing of the handle 12 to the housing 38.
- the first wall 44 and the guide member 46 may define a pair of slots 48 and 50 that are dimensioned to receive at least a portion of the protrusion 28 of the handle 12.
- the protrusion 28 of the handle 12 may have a first wall 52 that defines a tapered slot 54 that is dimensioned to receive the tapered guide member 46 of the housing 38.
- the tapered slot 54 and the tapered guide member 46 may facilitate "one way” loading of the cartridge 14 to the handle 12.
- the assembly of the tapered slot 54 of the handle 12 and the tapered guide member 46 of the housing 38 may result in a tapered interlock which secures the protrusion 28 of the handle 12 within the housing 38 of the interconnect member 16.
- the taper angle of the tapered slot 54 and the tapered guide member 46 may be about 1/8 of a degree per side to about 10 degrees per side, or even about 1 degree per side to about 5 degrees per side.
- the taper angle of the tapered slot 54 and the tapered guide member 46 may also facilitate the proper alignment and assembly of the handle 12 to the cartridge 14.
- the protrusion 28 of the handle 12 may have a first and second lateral projections 56 and 58 that engage the corresponding pair of side walls 60 and 62 of the housing 38.
- the first and second lateral projections 56 and 58 and the corresponding side walls 60 and 62 of the housing 38 may also be tapered to create a tapered interlock, as previously described.
- the first and second lateral projections 56 and 58 and the tapered slot 54 of the protrusion 28 may aid in rigidly securing the protrusion 28 within the housing 38 and prevent the cartridge 14 from unintentionally disengaging from the handle 12 during shaving.
- FIG. 4 an enlarged cross section view of the shaving razor 10 is shown, taken generally on the line IV-IV of Fig. 1 .
- the cartridge 14 is secured to the handle 12 by use of the interconnect member 16.
- the enlarged latch member 30 may have dimension, for example "w 1 ", that is greater than the width of the housing 38 in a neutral position, such that inserting the enlarged latch member 30 into the housing 38 causes the free end 42 to deflect from its original or neutral position.
- the free end 42 may have a flange member 64 that rides along the leading end portion 32 of the enlarged latch member 30.
- the leading end portion 32 may act as a ramp to facilitate the deflection of the free end 42.
- the flange member 64 may clear the leading end portion 32 and the trailing end portion 34 of the enlarged latch member 30 and engage the protrusion 28 of the handle 12.
- the flange member 64 may become securely positioned between the trailing end portion 34 of the enlarged latch member 30 and a front wall 66 of the distal end portion 26 of the handle 12.
- the trailing end portion 34 of the enlarged latch member 30 may have a steeper incline or taper than the leading end portion 32 to prevent the free end 42 and flange member 64 from disengaging with the protrusion 28.
- the release tab 22 may be joined to the free end 42 of the interconnect member 16 to facilitate the disengagement of the cartridge 14 from the proximal end portion of the handle 12.
- the user may lift or push the release tab 22 to the second position to disengage the flange member 64 from the protrusion 28.
- the flange member 64 may flex to an extended position as the flange member rides along the tapered trailing portion. Once the flange member 64 clears the tapered trailing portion, the free end 42 may flex back to its original position, thus ejecting the cartridge from the protrusion 30 of the handle 12.
- the tapered or ramp geometry of the leading end portion 32 may facilitate the ejecting of the cartridge 14 from the handle 12.
- the release tab 22 may also facilitate mounting the protrusion 28 on the housing 38 by opening up (increasing the width) the housing to aid in the insertion of the protrusion 28.
- FIG. 5 another embodiment of the present disclosure, which does not fall within the scope of the claims, is shown illustrating a shaving razor 100 having a handle 112 and a cartridge 114.
- the handle 112 may include a distal gripping portion 124 and a proximal end portion 126.
- the cartridge 114 may be detachably and pivotably mounted to the proximal end portion 126 of the handle 112.
- the cartridge 114 may be detachably and fixedly mounted to the handle 112.
- the cartridge 114 may be removed from the proximal end portion 126 of the handle 112 and replaced with a new cartridge 114 as needed by a user.
- An interconnect member 116 may be provided to detachably join the cartridge 114 to the proximal end portion 126 of the handle 112.
- the proximal end portion 126 of the handle 112 may include a pair of flexible arms 102 and 104 that facilitate the engagement and disengagement of the interconnect member 116 and the cartridge 114 from the handle 112.
- the pair of flexible arms 102 and 104 may define a generally key hole shaped slot 122 that provides for increased strength, durability and flexibility of the arms 102 and 104.
- the pair of arms 102 and 104 may each be provided with an enlarged finger pad 106 and 108.
- the enlarged finger pads 106 and 108 may have a generally oval geometry with a contoured or concave profile.
- the enlarged finger pads 106 and 108 may allow more force to be applied to the pair of flexible arms 102 and 104, while dispersing the force applied to the user's fingers, which may result in less discomfort during the attachment and removal of the cartridge 114 from the handle 112.
- the interconnect member 116 may have a pair of arms 118 and 120 that securely and pivotably connect to the cartridge 114.
- the opposing arms 118 and 120 may allow for an open space or window below the cartridge 114, which may improve the ability for water to rinse out the cartridge 114 after shaving.
- the interconnect member 116 may be a single integral component which is capable of detachably and pivotably coupling the cartridge 114 to the handle 112, without the need of separate components assembled to the handle 112 or the cartridge 114.
- the handle 112, the cartridge 114 and the interconnect member 116 may be molded from polymers such as high impact polystyrene (HIPS), but other semi-rigid polymers such as polypropylene (PP) and acrylonitrile butadiene styrene (ABS) may also be used.
- HIPS high impact polystyrene
- PP polypropylene
- ABS acrylonitrile butadiene styrene
- the handle 112 may be composed of more durable materials such as metals, composites, more rigid plastics or any combination thereof.
- FIG. 6 an exploded perspective view of the shaving razor 100 is shown illustrating the assembly/disassembly of the cartridge 114 and the handle 112.
- the pair of flexible arms 102 and 104 of the proximal end portion 126 of the handle 112 may each have a latch member 128 and 130 with a catch portion 132 and 134, respectively.
- the latch members 128 and 130 may be non parallel to each other and extend from the pair of flexible arms 102 and 104 at an acute angle projecting toward each other.
- the flexible arms 102 and 104 may each have an inner stop surface 142 and 144 which may contact each other as the flexible arms 102 and 104 are compressed together.
- the finger pads 106 and 108 may allow a user to apply more force to the flexible arms 102 and 104, thus it is possible to over compress the flexible arms 102 and 104 either instantaneously or over many repeated uses.
- the flexible arms 102 and 104 may fatigue and loose their plastic memory. If the arms 102 and 104 loose their plastic memory they will not return to their original positions which may result in a loose and unsecure attachment of the cartridge 114 to the handle 112.
- the inner surfaces 142 and 144 may act as a stop to prevent over compression of the pair of flexible arms 102 and 104, thus preventing premature failure of the arms 102 and 104.
- the inner surfaces 142 and 144 may contact each other when the arms 102 and 104 are sufficiently compressed to allow assembly of the handle 112 to the interconnect member 116.
- the cartridge 114 may be pivotably connected to the interconnector member 116 via the pair of opposing arms 118 and 120.
- the pair of opposing arms 118 and 120 may extend arcuately from the cartridge 114 to a housing 138.
- the housing 138 may define a tapered opening 140 that is dimensioned to receive the latch members 128 and 130 and cause them to deflect.
- the latch members 128 and 130 may each have a free end which acts as cantilever beam to facilitate the deflection of the latch members 128 and 130 as they are inserted into the housing 138.
- FIG. 7B illustrates an enlarged cross section view of a portion of the shaving razor 100, taken generally on the line VII-VII of Fig. 5 .
- the latch members 128 and 130 are fully inserted into the housing 138 and the cartridge 114 is secured to the handle 112.
- the flexible arms 102 and 104 may be compressed towards each other to insert the latch members 128 and 130 into the tapered opening 140 of the housing 138.
- the user may press against the finger pads 106 and 108 as the latch members 128 and 130 are inserted into the tapered opening 140 of the housing 138.
- the tapered opening 140 of the housing 138 may have a width dimension between a pair of opposing inner walls 150 and 152, that is smaller than a width dimension between the pair of catch portions 132 and 134, such that inserting the catch portions 132 and 134 into the housing 138 causes them (and/or the latch members 128 and 130) to deflect.
- the catch portions 132 and 134 of the latch members 128 and 130 may ride along the inner walls 150 and 152 of the housing 138 and engage one or more undercut sections 154 and 156 of the inner wall 150 and 152.

- the rear wall 160 may effect or interfere with the engagement or disengagement of the latch members 128 and 130 if they are inserted too far into the housing 138.
- the undercuts 154 and 156 may engage the respective catch portions 132 and 134 of the latch members 128 and 130 and prevent the latch members 128 and 130 from pulling out of the housing 138.
- the user may release the finger pads 106 and 108.
- the flexible arms 102 and 104 and the latch members 128 and 130 will attempt to return or spring back to their respective original positions.
- the housing 138 may be dimensioned to prevent the latch members 128 and 130 (and thus the flexible arms 102 and 104) from returning to their full respective original positions, thus causing the latch members 128 and 130 to exert a force against the inner walls 150 and 152 of the housing.
- the catch portions 132 and 134 may also exert a force against the undercut sections 154 and 156 of the housing 138.
- the force exerted against the housing 138 may be increased by increasing the width between the latch members 128 and 130 or decreasing the width between the inner walls 150 and 152 (which may also include the undercut sections 154 and 156).
- the interconnect member 116 may be secured more rigidly to the handle 112 by increasing the interference between the latch members 128 and 130 and the housing 138.
- the inner walls 150 and 152 and the latch members 128 and 130 may be tapered such as a tapered interlock is created when they are assembled to ensure proper alignment and attachment of the housing 138 to the handle 112.

- the tab member 230 of the handle 212 and the bottom surface 260 of the button 222 may have a key fit, such as a "T" shaped geometry.
- the tab member 230 may act as a support member and also as a return of spring element which biases the button 222 in a non actuated position.
- the distal end portion 240 of the button 222 may be supported by the recessed surface 228 and the tab member 230.
- the proximal end portion 242 of the button 222 may be supported by the free end 254 of the interconnect member 216.
- the tab member 230 and the free end 254 may apply a biasing force against the button 222.
- the latch members 244 may engage a respective undercut section 262 of the enlarged proximal end portion 226 of the handle 212 to secure the button 222 to the handle 212.
- the undercut section 266 may guide the latch member 244 as it travels in a downward direction when the button 222 is actuated.
- the undercut section 266 may also prevent the latch member 244 from disengaging from the handle 212 when the button 222 moves in an upward direction.
- the distal end portion 240 of the button 222 may contact the recessed surface 228 of the handle to prevent disengagement of the button 222.
- the latch member 246 and a corresponding undercut section 264 of the enlarged proximal end portion 226 are not shown, but function substantially the same way.
- the cartridge 214 may be mounted to the handle 212 by inserting the interconnect member 216 into the slot 250 of the enlarged proximal end portion 226 such that the guide members 202 and 204 are received by the respective slotted projections 232 and 234 (232 and 202 not shown for purposes of clarity).
- the free end 254 may deflect and engage an undercut 266 of the front wall 238 to secure the cartridge 214 to the handle 212.
- the free end 254 may contact a bottom surface 268 of the button 222, causing the proximal end portion 242 of the button 222 to toggle into a first position.
- the free end portion 254 acting on the bottom surface 268 of the button 222 may bias the button 222 in the first toggle position and may also act as a spring member to provide the user with feedback as the button 222 is actuated.
- the distal end portion 240 of the button may contact the recessed surface 228 of the handle 212 at an angle, as shown in Fig. 10 .
