Definitions
- the present disclosure relates to razors and more particularly to a dual sided razor.
- Dual sided razors incorporate switching of blade sides either by having a user to detach the cartridge from the handle, and or by rotating the cartridge about a vertical axis passing through the center of the handle. This poses the user with hassles in switching from the 1 st side of the cartridge to the 2 nd side of the cartridge and requiring a lot of time. Further, the blades are not flexible and hence do not comply or adjust to the user’s different skin surfaces and contours, thus compromising shaving performance. Still further, the design of the handles of such razors do not have symmetric profiles on the sides making it difficult to grasp and shave on both sides of the handle when the user shaves with the 1 st side of the cartridge and when the user shaves with the 2 nd side of the cartridge.

- the dual sided disposable razor and system razor 100 comprises a handle 10 which extends vertically with a first side 10a and a second side 10b.
- the first side 10a and the second side 10b have a symmetric profile about a vertical handle 10 axis X that passes through the centre of the handle 10. This allows the same level of comfort to the user while shaving with either 1st side of the cartridge of blades 41a, 41b, 41c, 41d of the cartridge 40 or the 2nd side of the cartridge of blades 41a, 41b, 41c, 41d of the cartridge 40.
- the dual sided disposable razor and system razor 100 has arms 20a, 20b integral with the handle 10 and projecting sideways from the top end of the handle 10 to allow grasping of a cartridge 40 that carries blades 41a, 41b, 41c, 41d on both sides of the cartridge.
- a first pivot 21a extends horizontally from an end of the first arm 20a.
- the blades 41a, 41b, 41c, 41d configured on both sides of said cartridge 40 are made of steel and the blade carrier and blades can flex and move over different contours of the user’s skin this will help to comply with the irregularities of the contour of a shaved surface.
- a second pivot 21b extends horizontally from an end of the second arm 20b.
- Both the first pivot 21a and the second pivot 21b facilitate rotation of the cartridge 40 along a common pivot axis Y, which biases the cartridge 40 either to the first side or the second side of the handle 10 depending if the 1st side cartridge is beiung used or the 2nd side of the cartridge is being used.
- This enables switching between the blades 41a, 41b, 41c, 41d disposed on the first side 10a and the blades on the second side 10b of cartridge 40 as desired by the user.
- This enables optimum usage of the dual sided disposable razor and system razor 100 as well as renders the dual sided disposable razor and system razor 100 affordable.
- the arms 20a, 20b and the cartridge are detachably attached to the handle 10 in a system razor version.
- a wide flexible barrier 30 is provided on the top end of the handle 10 so as to avoid inadvertent switching of sides by the user.
- the barrier 30 protrudes vertically from the top end of the handle 10.
- the barrier can be any shape or size and be stiff or flexible and can be made of any material.
- the barrier can have wide base or flange and narrow top or a wide top and narrow base and it can have holes in it and beany number of parts or materials.
- the flexible barrier 30 is a narrow barrier 30 as shown in the figure 2.
- the barrier 30 resiliently deforms under action of a swiveling force applied by the user.
- the barrier 30 has a smooth rounded profile for ease of switching.
- the barrier can be any shape or size and made of any material.
- a deflector 60 is provided at the center of the top end of the handle 10 on a disposable razor version and be on the top end and the middle of the swivel arms that are attached to the two sided razor cartridge for a system razor which the razor cartridge is removable from the handle.
- the deflector can be any shape or size and be made of any material and it helps to prevent inadvertent switching between the first side 10a and the second side 10b as the deflector 60 interacts with the barrier 30. However, when a preset force acts on the deflector 60, the deflector 60 resiliently deforms to allow biasing of the sides 10a, 10b of the dual sided disposable razor and system razor 100 as desired by the user, as shown in the Figures 1,2,4 and 5.
- the deflector 60 can be stiff and not move and not be able to resiliently deformed.
- the height difference from the deflector 60 and barrier 30 are at a longer distance from each other than if the deflector 60 and barrier 30 where directly above each other and vertical. This longer distance between deflector 60 and barrier 30 at the vertical point when the deflector 60 is above the barrier 30 creates a resistance. This way when the deflector 60 passes over the barrier 30 to switch the 1st side shaving side of the cartridge to the second shaving side of the cartridge the deflector 60 interacts with the barrier 30 while passing from the 1st shaving side to the 2nd shaving side.
- the barrier 30 acts like a barrier and it will keep the 1st shaving side on the 1st shaving side and or keep it on the second shaving side when the user wants to use the 1st or 2nd shaving side.
- a cavity 62 is defined into the inner surface of each of the arms 20 to engage with the deflector on the bottom of the cartridge 40.
- This cavity 62 and deflector 60 can be located anywhere on or in the razor cartridge 40 and on or in the arms 20 and be any shape size or design to function in the same manner.
- the cavity 62 acts like a barrier and it will keep the 1st shaving side on the 1st shaving side and or keep it on the second shaving side when the user wants to use the 1st or 2nd shaving side.
- This deflector 60 and cavity 62 can be used in conjunction with the deflector 60 on the bottom of the cartridge and the barrier 30 described in this application or one way can be used only or both ways.
- the deflector 60 and the cavity 62 can be located anywhere in or on the arms 20 or in or on the razor cartridge 40.
- the location of the deflector 60 and the cavity 62 can be have 2 or any number of deflectors 60 and 2 or any number of cavity 62. In one embodiment there could be 2 deflectors 60 and 1 cavity 62 and each deflector 60 can be located off center as compared the deflector 60 shown in Figure 14.
- the location of the deflector 60 off center can be any position and it allows the cartridge 40 to be in the right position, angle or degree relative to the handle so the user can start shaving the 1st shaving side of the cartridge.
- the user can move or tilt the cartridge in the opposite direction or position of the 1st shaving side cartridge 40 and 1st position of the deflector 60 will pass the cavity or barrier 62 and then while its still tilting in the opposite direction of shaving side 1 it will pass the 2nd position of the deflector 60 and now the razor cartridge will be in the perfect angle, position or degree relative to the handle so the 2nd side of shaving can be in the correct position and be used.
- These deflectors 60 and cavities 62 help keep the cartridge on the 1st shaving side or the 2nd shaving side and helps keep the razor cartridge 40 in the right position for shaving the 1st shaving side of the cartridge and for the 2nd shaving side of the cartridge 40.
- the deflector 60 and cavity or barrier 62 can be any shape or design or be any type of material.
- each of the arms 20 are configured without any cavity and can function and have all the features like described for Figures 14, 15 and 16 above.
- the swivel arm 20 and cartridge 40 are configured to be in a correct starting angle / position to begin shaving, which aides and allow easy handle 10 and cartridge 40 attachment for the consumer.
- the engagement between the cavity of each side of the cartridge 40 shown in Figure 17 and the swivel arm prong shown in Figure 18 can have many benefits to the two-sided razor and figure 11 and figure 14-18.
- the inside cavity can have prongs, protrusions or cavities that and can interact with prongs, ratchet, gears, protrusions or cavities on the prong of the swivel arm that goes insides the cavity on each end of the cartridge.
- prongs, ratchet, gears, protrusions or cavities can be at any degree on a 360-degree radius on the prong and the cavity and there can be one to any number. This will inhibit the swivel arm to swing freely from one side to the other and allow for an easier connection for the consumer.
- These prongs, ratchet, gears, cavities or protrusions on the swivel arm and end cavities on the cartridge for example would be at 8 o’clock position on one side and 4 o’clock on the other side when the cartridge 40 and swivel arm is in the upright position. So when the user gets the two sided razor cartridge the cartridge and swivel arm will be in the 4 o’clock position and ready to be attached The cartridge and swivel can flex back any amount and this is just for visual reference.

- the user would use the cartridge currently on the razor cartridge and when the 1st sides of the dual sided razor cartridge is dull, then the user would flip the cartridge back over to the other side. This means when the 1st side is being used the top part of the cartridge is angled back towards the back of 2nd sides of the cartridge and the 2nd handle side. When the 1st side if the razor cartridge is dull, then the user would toggle and flip the top of the razor cartridge opposite direction so now the top parts of the cartridge is angled toward the 1st side of the cartridge and the 1st handle side.
- the process of flipping the cartridge from the 1st side to the 2nd side can be done any way possible known now or developed or learned in the future.
- One way to flip from one side to other...the consumer can switch sides and move by using their fingers. Or they can turn the razor upside down and using the counter top and touch the top section to the counter top or flat surface and push the top of the razor cartridge until flips to the other side, this is a real fast and easy way without using your fingers.

- Flex Blades - Floating Blades- Moving Blades The two sided razor cartridge can have flexible blades, floating blades or moving blades on one side and or both sides of the two-sided razor cartridge. I will use the term Flex blades to mean Flex blades, floating blades or moving blades.
- the flex blades allow the razor blades to flex or move according to the contour of the user’s skin or the surfaces it shaves over. The flex blades move within the cartridge and any portion of the razor blade that is exposed from the razor cartridge. The flex blades make the shave more comfortable and the flex blades allow the blades to cut the hair as the cartridge and flexible blades go over the user’s skin.
- the Flex Blades - Floating Blades- Moving Blades can be designed any way known today.
- the Flex Blades - Floating Blades- Moving Blades can have one to any number of blades on each side of the cartridge.
- the Flex Blades - Floating Blades- Moving Blades can be attached to a fixed carrier or flexible carrier or axis or frame and the Flex Blades - Floating Blades- Moving Blades can be all connected or separate pieces.
- Each of the Flex Blades - Floating Blades- Moving Blades on one side of the razor cartridge can move at the same time or separately.
- the Flex Blades - Floating Blades- Moving Blades can be connected to the 2nd shaving side and or opposing sides of flexible blades or they can all move together or independently.
- the flexible blades move on one side that’s being used to shave with, then the opposite side not be used; the flexible blade can move as well allowing for improved flow through of hair and shave cream, gels etc.
- the rinse ability of the cartridge is better because of the movement of blades.
- the Flex Blades - Floating Blades- Moving Blades on both sides can work in unison or move independently.
- the blade carrier or blade frame where the blade is welded or attached to it can be one piece or several pieces and can have a hinge type, flex type or spring type mechanism that allows the blade to flex, and move and it can also move while on the blade carrier or blade frame and this allows the blade to flex in a more controlled way instead of relying on plastic or other components to flex the blade when in a cartridge like typical flex blade, floating blade razor cartridges.
- the hinge type, flex type or spring type mechanism that allows the blade to flex can be located anywhere on the razor cartridge, blade, blade carrier, blade frame, blade holder.
- Typical flex blade razor cartridges have plastic type tabs that the blades rest on and when it goes over different contours or surfaces the blades moves and so does the tabs that the blades rest on; giving it the flexibility to move up and down or any direction.
- the Flex Blades - Floating Blades- Moving Blades can rest on flexible and moving surfaces or tabs. These tabs and moving surfaces can be located in the cartridge, blade carrier or blade frame or any location and can hold both sides of the flexible blade, blades and or blade carrier or blade frame or just one side and they can move separately or together with the opposing 2nd shaving side Flex Blades - Floating Blades- Moving Blades.
- tabs and moving surfaces can be located in the cartridge or any location and can hold both sides of the flexible blade, blades and the flexible blades can move separately or together with the opposing 2nd shaving side Flex Blades - Floating Blades- Moving Blades.
- These tabs can be on the ends of the cartridge and can be any length and can run under the blade carrier or blade or blade frame or any location
- the blade carrier of a two-sided razor is typically flat and the angled on both sides where the blade is permanently attached to both sides by welding or other means or it can be one piece.
- the blade carrier or blade frame can flex or hinge allowing movement instead of being fixed. This can be done any way known today or developed ion the future. It can also be done be stamping holes in the blade carrier when it’s made to allow a hinge effect and allow the middle to move up and down when the user shave over the different shaving surfaces. This will also give more holes in the middle of the razor to allow more improved water flow and rinse ability.
- the ends of the blade carrier will allow the Flex Blades - Floating Blades- Moving Blades to be fixed in the razor cartridge.
- the cartridge will also be design to hold these the Flex Blades - Floating Blades- Moving Blades so they can move.
- the design of the cartridge holding the Flex Blades - Floating Blades- Moving Blades can be designed any way possible to accomplish this and allow for precise geometry of the razor cartridge.
- the angled surface on the blade carrier where the Flex Blades - Floating Blades- Moving Blades are attached to and where it’s connected to the flat horizontal surface can have a flex point or hinge point where it moves and flexes in an upward only movement or downward only movement or movement of upward and downward or any direction. This can be accomplished by any way known now or developed ion the future.
- One embodiment can have the holes and design holes that allow this joint to flex and spring and move up and down or just one direction.
- the blade carrier and or blade frame can be any shape size or design and made of any material.
- the blades on each side of the two-sided razor can be welded to a flat blade or blade carrier then the middle can be bent allowing the two sides to be angled downward to create the right angle for the two sided razor cartridge.
- the area being bent can be done by machine, laser welding to heat the surface to allow the material to bend.
- the bend point or hinge point can have holes to allow the flexibility to bend and allow for more water flow through and better rinse ability.
- the Flex Blades - Floating Blades- Moving Blades are attached to and where it’s connected to the flat horizontal surface can have a flex point where it moves and flexes in an upward only movement or downward only movement or movement of upward and downward or any direction.
- the Flex Blades - Floating Blades- Moving Blades can be bent blades, meaning a blade that is bent or a blade that is connected to a blade carrier and bent.
- the two-sided razor can hold these independent bent blades separately on each side or together and the two sided razor cartridge can be designed to hold these blades and allow for blade movement and flexing of blades on each side of the razor cartridge. So for example a 3 blade two-sided razor cartridge having 3 independently flex blade on one side and 3 independent flex blades on the other side.
- the blade carrier or blade frame can be flat at the top and angled downward on both sides where the Blades are permanently attached. On the opposite ends of the flat surface a portion can stick out and be shaped any way or size possible. These end points can be placed into the two-sided razor cartridge pockets or swivel pockets or cavities, in a blade frame, blade carrier or any location that will allow the blade to flex, float or move thus allowing the blades to cut the hair over different contour shaving surfaces. These cavities or swivel points can be any size or shape and be designed to allow the cartridge to only swivel within a certain range and angle in each direction or any direction.
- the blades on the opposite side can move as well but the opposite side is not being shaved with.
- side 1 blade being shaved with is moving upward then the 2nd shaving side opposite of side this blade is moving downward.
- the movement blades on the 1st shaving side can move the opposite direction the 2nd shaving side or they can move the same or any direction.
- the angled surface on the blade carrier where the Flex Blades - Floating Blades- Moving Blades are attached to and where it’s connected to the flat horizontal surface can have a flex point where it moves and flexes in an upward only movement or downward only movement or movement of upward and downward.
- the angles of the blade frame or blade carriers can have a flex point, hinge point and or spring point and it can be located anywhere.
- the angles of the blade or blade frame or blade carrier can flex or the flat surfaces.
- Any of the embodiments disclosed can have the Flex Blades - Floating Blades- Moving Blades that move upward only or downwardly only or it can move up and down or any direction.
- the Flex Blades - Floating Blades- Moving Blades can move separately and or independently and or simultaneously.
- the two-sided razor cartridge holding the Flex Blades - Floating Blades- Moving Blades can be one to any number of pieces, in one embodiment the razor cartridge can be one piece for example and the Flex Blades - Floating Blades- Moving Blades can be placed on both sides of the one-piece cartridge and an aluminum clip can hold the flexible blades in place or any other type of connection or end caps already disclosed in previous applications.
- the two-sided cartridge with flexible blades can be any shape size and be made of any material known now or a combination of materials and it could be assembled with one piece or a two-piece cartridge or any number pieces of cartridges.
- the Flex Blades - Floating Blades- Moving Blades & Blade Carrier and blade frame can be any shape size and be made of any material known now or a combination of materials and it could be assembled with one or any number pieces.
- the Flex Blades - Floating Blades- Moving Blades can be attached any way to permanently attach the blade to the Blade Carrier and blade frame.
- the blade carrier or frame can be made of the Flex Blades - Floating Blades- Moving Blades, it can be on the same surface.
- the blade can be the blade carrier or blade frame.
- the Flex Blades - Floating Blades- Moving Blades can be bent or made into a shape that allows the blade to angle downward like disclosed in this application, so the blade is the blade carrier in one.
- the blades can be welded to this frame and any location to give precise geometry and progressive geometry.
- a central access can connect all blade carriers, blades, blade frames individually or all of them.
- the central axis can be located in the center of Flex Blades - Floating Blades- Moving Blades and blade carriers or blade frame or be locates on the ends and the middle of the Flex Blades - Floating Blades- Moving Blades or any location.
- the blade central axis can be located anywhere and have one to any number of them.
- the central axis can have flex, spring or hinge areas and or points that allow all the blades to flex and move.
- the blades where this central Access can be located in anywhere on blade supports, or blade frame or even the blades and can run through all the Blades supports, blade carriers or blades or be connected to one or all the Blades supports, blade frame or blades and in between all the blade supports there can be breaking points, hinge points flex points or spring points which allows the blade to flex or move inward or outward or up and down or any direction each time the blade is cutting through hair and going over different shaving surfaces or contours.
- This access can be connected and be located anywhere on the flexible Blades or the blade carrier or any part of the blade connection areas or anywhere within the cartridge to where it can allow the blades to flex.
- the central axis can have areas on it where they have guides where the blade carrier and blade can move back and forth and in a precise and controlled way
- the blades on a two sided razor cartridge could be welded to a frame and this frame could hold one to any number of blades and this frame can be independent or connected to the other side of second side of the cartridge blade frame and blades.
- the frame would have areas where the blade could be angled or welded to a portion that’s already angled and the sections are attached to the frame and can move upward or downward and could possibly move in and out so the Blades can flex and move while the user shaves over the different services.
- this frame can be inserted into one side of the cartridge and the same thing with the other side of the cartridge and then assembled.
- the frame can include both sides of the blades, blade carrier or frame in one or any number of pieces and then place into the razor cartridge to be assembled.
- the blade carrier that is currently used in the market has flat at the top and angled on both sides where the blade is permanently attached.
- the blade carrier and frame can use a double edge blade and be bent to make the blade be angled on both sides of the blade so it’s one piece that has a blade carrier or frame and the blade and no welding required.
- the blade is the blade carrier.
- the blade carrier or blade frame of a two-sided razor is typically flat and the angled on both sides but can be any shape size or design. If it was flat and in order to have precise razor geometry and progressive geometry, the blade carrier or frame that cuts the hair first is lowest blade on the razor cartridge and this blade would not be exposed as much as the next blade above it and the blade after that. So the 1st blade carrier or blade frame flat section can be shorter so it allows the blade welded on both sides not to be exposed as much on both sides.
- the 2nd flat area of the blade carrier or frame can be slightly longer than the 1st flat portion of the blade carrier or frame, this allows the blade welded to it or attached to it on both sides are to be exposed a little further than blade 1 on both sides that below it.
- the 3rd flat area of the blade carrier or frame is a little longer than 2nd and 1st and the blade on both sides is exposed more than the 2 blades and 1 blades below the 3rd flat area, this way the blades have progressive geometry and can cut progressively.
- the 1st blade cuts the hair and the 2nd blade passes and cut more of the hair and the 3rd blade cuts the remainder of the hair.
- each stack can have a flex mechanism located anywhere on the blade carrier, blade frame, flex blade, main frame holding the blade, carrier or blade, blade ends or each end or middle or any location.
- Each stack of the Flex Blades - Floating Blades- Moving Blades and the blade carrier or blade frame can have a flex mechanism in between each stack and the lowest flex blade and or carrier section can have a mechanism that is below to touch another part of the frame or cartridge since there’ no blade below it.
- This flex, spring or hinge mechanism can be located anywhere on the razor cartridge, blade or frame or carrier.
- This flex mechanism can be made or any material and work any way possible to allow each blade to flex and move up and down or any direction so the blades glide over the different contours and surfaces of the user’s skin.
- These flex points or areas can allow 1st shaving side of the blade to move and the opposite side of the 1st side (the 2nd shaving side) to move in the same direction or opposing direction or any direction.
- the flex, floating and moving blade can move any direction. So while the user is shaving, the flex, floating and moving blade can move and allow the shave cream, shave gel or shave butter and hair being cut to move because the flexible blade on both sides are moving allowing a flow through to be constantly moving all the way to the 2nd side not being used and exiting the razor cartridge.
- the blade carrier or blade frame top flat surface can have holes and fit a control axis that goes through all the stacked Flex Blades - Floating Blades- Moving Blades.
- the control axis can be located anywhere and it can interact with each blade carrier or blade frame where the blade is permanently attached.
- the control axis point or points can interact with blade carrier opening and allow the Flex Blades - Floating Blades- Moving Blades to flex and move. It can be designed to control the movement of the blade precisely because it’s steel and not plastic. It would allow the blade to move within all tolerances for a close comfortable shave.
- the central axis interacts with the blade carrier opening the blade moves and as the blade moves the blade carrier moves using the axis as a guide.
- This axis point and axis guide can be located anywhere and even on each opposing end.
- the axis is guide for how much the flexible blade or blade carrier can move.
- the axis and blade carrier interaction point or points can be located anywhere and can work any way to achieve the same effect.
- the blade carrier or blade frame can be welded or attached together.
- the blade carrier or blade frame opposing ends can ride or rest on the ends of the cartridge.
- the ends of the cartridge can have pockets or cavities that the ends rest on and they can be tabs. When the user shave then the blades move on the tabs or these pocket or cavities hold the blade carrier ends.
- the blade carrier or blade frame ends or opposing ends can be stacked above each other and these ends can have spring or flexing technology or materials or features that allow the blade and the blade carrier to flex and or move.
- the blade carrier or blade frame ends that blade are welded or permanently attached to one another are placed in a razor cartridge.
- One way it is disclosed in previous application is the blade carrier sits in the razor cartridge halves; these cartridge halves (2 pieces) have grooves or teeth that the blade carrier opposing ends are placed in half of each cartridge.
- the teeth or grooves or pockets are typically flat to hold the blade carrier end and blade carrier and blade in a fixed position so it does not move.
- a new way for this design to have flexible and floating and moving blades is to change the design of the teeth and grooves and pocket. Instead of teeth, pocket or grooves that hold the opposing blade carrier ends being flat, the middle section can be narrower and the outer ends of the pocket, grooves or teeth can be wider.
- the blade carrier ends rest on the middle section of the groove or teeth or pocket in a fixed position (blade resting position) and when the user shaves over different contours and shaving surfaces the blade carrier ends move or tilt upward or downward depending on the surface being shaved.
- These outer ends of the teeth, pocket or grooves can have precise limits and measurements of rotation so it can only move a certain amount so it can be kept in precise tolerances.
- the blade carrier ends moving in a grove or teeth pocket area is more precise and accurate than typical flexible razors that depend on plastic tabs that the plastic rest on and move up and own. The plastic tabs can be off to due to mold injection in consistencies.
- the blade carrier ends rely on steel to move in a plastic pocket, teeth or groove area and the movement will be more precise.
- the pocket teeth or grooves can be flat shape but have more space above and below the blade carrier, blade frame to allow the blade to move.
- the blade carrier ends rest on the middle section of the groove or teeth or pocket in a fixed position (blade resting position) and when the user shaves over different contours and shaving surfaces the blade carrier ends move upward or downward depending on the surface being shaved.
- These outer ends of the teeth, pocket or grooves can have precise limits and measurements so the blade and blade carrier can only move up and down a certain amount for a comfortable shave using flexible technology.
- [00209] can be switched between its blade sides without dismantling of the cartridge
- [00210] is user friendly as flexible blades make it easy for the razor to shave irregular surfaces
