DUAL SIDED RAZOR
CROSS REFERENCE TO RELATED APPLICATIONS
100011 This application claims the benefit of U.S. Provisional
Application No.
62/943,438, filed December 4, 2019, the contents of which are incorporated by
reference
herein.
FIELD OF THE INVENTION
100021 The present disclosure relates to razors and more
particularly to a dual
sided razor.
BACKGROUND
100031 The background information herein below relates to the
present disclosure
but is not necessarily prior art.
100041 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"`I 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 1st side of the cartridge and when the user shaves with the
2nd side of the
cartridge.
100051 There is, therefore, felt a need of a dual sided razor
which overcomes the
aforementioned problems.
SUMMARY

1001011 Referring to figures 1-28 a dual sided disposable razor or a system
razor
100 will now be described, in accordance with an embodiment of the present
disclosure.
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.
1001021 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.
Similarly, 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,

WO 2021/113315
PCT/US2020/062824
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 In another embodiment, the arms 20a,20b and the cartridge are
detachably attached to the handle 10 in a system razor version.
[00103] 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. In another embodiment, 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. In another embodiment, 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.
[00104] 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
- 11 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
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. In another embodiment, as shown in the figures 14-16 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. This way when the deflector 60 passes over the
cavity 62 to
switch the 1st side shaving side of the cartridge to the second shaving side
of the
cartridge the deflector 60 interacts with the cavity 62 while passing from the
1st shaving
side to the 2nd shaving side. 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. It can be any shape or design to serve the same function. 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. When the blades are
dull and the
user wants to start using the 2nd 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
- 12 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
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. In still another embodiment, as shown in the figures 17 and 18, 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.
1001051 In another embodiment, 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. These 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.
1001061 When the first side is dull the user can disconnect the cartridge and
move
the swivel arm in the opposite direction toward 8 o'clock and then it will
click past the
- 13 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
prongs, protrusions or cavities on the swivel arm and the cartridge end cavity
and the
cartridge will now be in the right position and starting angle to use the
second side of the
cartridge. Now the cartridge can continue be flexible and swivel from the 8
o'clock
position and upward toward 10 or 11 o'clock The cartridge and swivel can flex
back any
amount and this is just for visual reference. This is embodiment can be used
for the
cartridge that has a deflector to pass to switch shaving sides and this can
aide the
deflector and keep the cartridge in the correct starting angle / position to
begin shaving
for the 1st shaving side of the cartridge and the 2nd shaving side of the
cartridge. This
embodiment can be used for any cartridge mentioned in this application or
previous
applications.
[00107] The floating / flexible blade cartridges 40 is
configured to be constructed
in regular as well as irregular shapes. If the blade can move or be flexible
within a
cartridge on both sides of a two sided razor to allow a close and comfortable
shave, then
it can be done with any combination described and or with any modifications.
[00108] The dual sided disposable razor and system razor 100 further comprises
cushions 24 provided on an operative end of each of the first arm 20a and the
second arm
20b. The cushions 24a,24b provide shock absorption during shaving by a user,
as the
cartridge 40 sides contact the surface of the arms 20a,20b, as shown in the
Figures 6-8.
(Figure 6-8 does not show the cartridge 40 in contact with the arms)
[00109] The rubber on the swivel arm 20a or 20 b can be any size shape or any
material that is soft and gives the cushion. A type of rubber material can be
chosen
depending on the density that is required. The whole idea with rubber on the
swivel arm
20a and 20b will be able to give the cartridge 40 support when it's in contact
with the end
caps 50. Disclosed in previous applications that the end caps have arms or
legs 24 c, 24 d,
24 e, 24 f on both ends where it is in contact on two parts of the swivel arm
Figure 6 24
an and 24 b that touch the end caps as one side is used, then when the user
flips or tilts
the cartridge 40 so you can use the second side of shaving then the other set
of rubber on
the swivel arm 24 an and 24 b is in contact with the end caps 50. This gives
support while
- 14 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
shaving so as the cartridge 40 can glide over different surfaces on the
consumers face or
skin or body but the cartridge 40 will be able to flex and move back-and-forth
with
comfort. The rubber can cover the entire swivel arm like in Figure 8 or just
be in sections
like in Figure 7 or any part of the swivel arm 20 and the swivel arm can be
made of
plastic with rubber sections or it could be any type of material or
combination of
materials. The endcaps 20 and end caps 50 can be any shape, size or design.
The cushion
areas can be one to any number of cushion areas and located anywhere on the
arms 20 or
end caps 50.
1001101
Similarly, cushions 24c,24d,24e,24f are provided at the bottom of the end
caps to enhance shock absorption, as shown in figures 9 and 10. The use of the
end caps
50 and the swivel arm areas 24a and 24b eliminates reliance on dedicated
tracks like 24g
that need to be provided if used with a pushpin. The rubber or cushion areas
on the caps
50 can be any size shape, design or any material that is soft and gives the
cushion. A type
of rubber material can be chosen depending on the density that is required.
The whole
idea with rubber on the end caps will be able to give the cartridge support
when it's in
contact with the swivel arm 20. The end caps 50 can have rubber or cushion
material the
swivel arms 20 can have rubber or cushion areas or one can have the rubber or
cushion
material and the other parts can be solid and have no cushion materials. In
one
embodiment the end caps 50 have arms 20 on both ends where 24a and 24b rubber
and
rubber and cushion areas are in contact with two parts of the end caps 50, 24c
or 24e
which can have been solid material or have cushion material. When the 1st
shaving side
is dull and used then the user can flip the cartridge 40 in the opposite
direction so you can
use the second shaving side of the cartridge 40. When this happens then the
other set of
rubber or cushion areas 24a and 24 b that are opposite sides of 24a and 24b
are in contact
with two parts of the end caps 50, 24d or 24f of the end caps 50. This gives
support while
shaving so as the cartridge glides over different surfaces on the consumers
face or skin or
body but the cartridge will be able to flex and move back-and-forth with
comfort. The
rubber can cover the entire area of the end cap 50 like shown in Figure 10 or
just be in

sections like shown in Figure 9. or be in any part of the end cap 50. The end
cap 50 can
be made of plastic with rubber sections or it could be any type of material or
combination
of materials. The end cap 50 could be any shape or size
1001111 End caps 50 are attached on the ends of said cartridge 40 A first
groove
52a and a second groove 52b are configured on the bottom portion of each of
the end
caps 50 to restrict the cartridge 40 to either the first side 10a or the
second side 10b,
thereby preventing inadvertent switching by the user, as well as switching
when desired
by deliberate application of force or pressure as shown in the Figures 19 and
20.
1001121 Figure 20 shows that a top portion of the swivel arm 20 is pointed and
that
the end cap 50 or the portion that holds the cartridge together on the ends
and this could
be part of the cartridge it might not be an end cap 50 it could be part of the
cartridge
design that it has the shapes that it has pockets 52a and 52b and has a
deflector in
between those two and then you have the top portion of the swivel arm 20 and
when you
shave with the first side the top of the swivel arm 20 is in cavity 52a and
when the user
switches sides the top portion of the swivel arm 20 is in cavity 52b.
1001131 When the user shaves the cartridge 40 end caps 50 and the portion 24c,
24d, 24e and 24f rest against the swivel arm 24a and 24b portions to give the
cartridge 40
support while shaving and the 52a and 52b pockets or cavities can keep the
cartridge 40
on the 1st shaving and prevent it from switching to the 2nd shaving side of
the cartridge
40 until the user wants to switch shaving sides The rubber or cushion material
on the end
caps 5 or swivel arm 20 gives support while shaving so as the cartridge glides
over
different surfaces on the consumers face or skin or body but the cartridge
will be able to
flex and move back-and-forth with comfort. Regarding Figure 19 and Figure 20
the
design of the end caps 50 pockets & legs and swivel arm 20 can be any shape,
any design
and be made of any material and be any number of pieces. The end caps 50 in
Fig 19 and
Fig 20 can have no end caps and be clips or parts or any design to hold any
number of
cartridge 40 together.

1001141 Arm prongs 22 having a toothed profile as shown in the figure 11 are
attached to each of said first arm 20a and said second arm 20b. This
facilitates provision
for mounting a ratchet while the arm prongs enact the pinion. Such a ratchet
and a pinion
arrangement allows for switching from the 1st shaving side and the 2nd shaving
side so
the cartridge 40 does not move freely and can be controlled by the gears in
the prong 22
and the pinion inside the cartridge 40 (we need to show the hole in the
cartridge 40). The
holes in the cartridge 40 can have one to any number of gears as well or
deflectors,
barriers or cavities that interact with the prong 22. The prong can have one
to any number
of gears, cavities, deflectors or barriers. The prongs 22 and the cartridge 40
prong holes
the area where the prongs go inside of can be any shape, any design, any
function and
any material. The prong 22 and cartridge 40 prong holes can have deflectors,
barriers or
cavities and be in the right position so the cartridge 40 is in the ideal 1st
shaving side
position relative to the handle. When the user moves the cartridge from the
1st shaving
side position to the 2nd shaving side position, then the prong 22 and
cartridge 40 prong
holes can have deflectors, barriers or cavities and be in the right 2nd
shaving side position
so the cartridge 40 is in the ideal 2nd shaving side position relative to the
handle The
prong 22 in Fig. 11 shows a ratchet design so the cartridge 40 can be rotated
at any angle
or direction relative to the handle.
1001151 In an embodiment, the dual sided razor 100 is a disposable type.
1001161 In one embodiment the dual sided razor 100 is a system razor type
where
the cartridge can be removed and replaced from the handle with a new two sided
razor
cartridge.
1001171 In another embodiment, the handle is as shown in Fig 3;
1001181 The dual sided razor has floating or flexible blades
(41a,41b,41c,41d,41e
as shown in various embodiments shown in the figures 24-27. which can be any
number
of blades on each shaving side of the two sided razor cartridge. The flexible
blades are
pivotable about a blade pivot axis (44) in either sense of rotation along the
blade pivot
axis 44. This results in upward or downward deflecting of the pivotable
surfaces of
- 17 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
blades. The blade pivot axis (44) location is variable with in the cartridge
and designed to
cater the needs of the user. In another embodiment, the flex blades
41a,41b,41c,41d,41e
are floating blades axis can swivel either way possible and/or flex any way
possible
within the cartridge The flex or floating blades attached to a blade carrier
can use tabs
(plastic or any material) on the cartridge on one side or both sides to aid in
the movement
of the blades and keep the blades in the proper blade exposure and correct
razor
geometry. The flex or floating blades 41a,41b,41c,41d,41e attached to a blade
carrier can
use the end caps to keep the blades in the proper blade exposure and correct
razor
geometry. The blade pivot axis (44) is provided on a blade carrier (45) as
shown in
Figure 22. The blade carrier 45 as variable geometry with respect to design,
shape, size,
form, angle, thickness. The blade carrier 45 is made of a stiff material.
Figure 23 shows
cartridge 40 having blades (41a,41b,41c,41d,41e) assembled into blade pockets
(46). The
blade pockets 46 are located at a variable location either inside the dual
sided razor
cartridge and or the end caps. These pockets 46 facilitate movement of the
blades and
maintain the blades in an optimum exposure configuration and razor geometry.
The
dimensions of the blade pockets (46) are such that during the rotation of the
blades, can
be any number of blades (41a,41b,41c,41d,41e), a clearance is provided so as
to facilitate
free rotation of blades while a user shaves. The blade pockets 46 in the
cartridge or the
end caps can areas where it keeps the blade in perfect blade exposure position
and allows
the blade to float and move over different skin contours or skin surfaces The
dimensions
of each of said blades (41a,41b,41c,41d) are variable. In an embodiment as
shown in the
figure 27, the blades have bent profile along the width of the blades. In
another
embodiment as shown in the figure 27, the bent blades have extended edges
1001191 The dual sided razor (100) is configured with retention bumps (12)
that are
provided on the handle (10). The retention bumps (12) are configured to be
inserted into

1001201 The switching of the handle between the first shaving side 10a or the
second shaving side 10b is achieved by the user without detaching the
cartridge 40 from
the handle 10. To switch sides of the holding position of the handle from 10a
to 10b, the
user simply grasps the handle 10 in the 10a position and rotates it until the
handle 10b is
in the user hand ready for using the 2nd shaving side. To switch the cartridge
40 shaving
sides from the 1st shaving side to the 2nd shaving side the user simply holds
the handle
and applies pressure in the direction at the top end of the cartridge 40 rests
on a surface
and pushes so the cartridge 40 tilts from the 1st shaving side of the
cartridge 40 position
relative to the handle to the 2nd shaving side of the cartridge 40 position
relative to the
handle. Now the handle 10b and the cartridge 40 is the correct position to
begin shaving
the 2nd shaving side of the cartridge 40. This facilitates rotation of the
cartridge 40 about
the axis Y of the first pivot 21a and the second pivot 21b. As a result of
this rotation the
barrier 30 comes in contact with the deflector 60, and as the intensity of
pressure applied
the user increases further, a snapping action takes place which results in
switching
between the first side 10a and the second side 10b of the cartridge 40.
1001211 In another embodiment to switch the cartridge 40 shaving sides from
the
1st shaving side to the 2nd shaving side the user simply holds the handle with
one hand
and can hold the cartridge 40 ends or end caps 50 and manually apply pressure
in the
opposite direction the cartridge 40 is angled or tilted (1st shaving side
position) until the
cartridge 40 is tilted and angled in the opposite direction of the 1st shaving
sided position
so it can be in the 2nd shaving side position relative to the handle. Now the
handle 10b
and the cartridge 40 is the correct position to begin shaving the 2nd shaving
side of the
cartridge 40. This facilitates rotation of the cartridge 40 about the axis Y
of the first pivot
21a and the second pivot 21b. As a result of this rotation the barrier 30
comes in contact
with the deflector 60, and as the intensity of pressure applied the user
increases further, a
snapping action takes place which results in switching between the first side
10a and the
second side 10b of the cartridge 40. The way the user switches from the 1st
shaving side
to the 2nd shaving side can be done any way possible to achieve the same
effect.

1001221 In another embodiment as shown in the figures 32A - 39, blade fingers
47
are provided on each of the rear portion of the blades 41a,41b,41c,41d. The
blade fingers
47 offers a cushioned support to the blades 41a,41b,41c,41d to facilitate
accurate
traversing of curved surfaces of the face of the user The blade fingers 47
allow the blade
41a,41b,41c,41d to rest on the blade fingers 47 on both ends of the cartridge
40 and when
the user shaves, the blades 41a,41b,41c,41d are able to move as it goes over
different
contours and surfaces thus allowing for less irritation and add more comfort
while
shaving. Blade fingers 47 are known in the market, but this invention allows a
single
cartridge 40 to have two sides of shaving and both sides of the cartridge 40
has blade
fingers 47, which is currently not used in the market. In another embodiment
as shown in

Currently, the razors available in the market have the blades inserted
from
the front side. So there are many advantages to this new two sided razor
design to be able
to adapt to current razor cartridge 40 assembly machines Having two assembly
lines like
the standard single sided razor cartridge assembly lines that hold one side or
half of the
two-sided razor cartridge and then join them together at the end of the
cartridge
automation assembly line. This way of assembly is more practical which
utilizes the
current assembly line equipment without having to be modified, thus will be
easier to be
manufactured instead of designing a new manufacturing equipment. In an
embodiment,
the dual-sided razor cartridge 40 is configured to constructed so the blades
are inserted
and assembled from the backside of each two-sided cartridge 40 instead of the
front side.

to allow the consumer to use the 1st side of the razor and when dull switch to
the second
side faster and easier. This makes using this dual sided disposable razor more
convenient
for consumers and to allow them to have 2 sides of fresh blades every time
they buy and
use a disposable razor. To offer twice the shave with every disposable razor
they buy is a
huge value proposition for the consumer. Consumers always love a new set of
blades and
when they buy this dual sided disposable razor it allows consumers to have 2
sets of fresh
blades to use during each use There's 1 disposable razor but it offers many
benefits like
twice the shave and the opportunity to use 2 sets of blades during the entire
life of using a
disposable razor The disposable razor handles currently used in the market,
the handles
are used one time, and so this dual sided disposable razor allows consumers to
use the
handle twice. It allows for a longer life handles and less thrown away
prematurely. The
most important feature is the consumers can get twice the life out of their
disposable
razor which is never been offered before until now. Consumers would benefit
from
having two shaving cycles or uses every time they buy this new dual sided
disposable
razor. The consumer will also have two sets of fresh blades to use every time
they use
and buy disposable razor cartridges. This creates a better value proposition
for the

consumer when they get twice the life out of every disposable razors instead
having only
1 shaving use.
1001551 Handle
1001561 The dual sided disposable razor handle is symmetric handles that can
be
held have two separate uses on both sides. Old safety razors usually have a
round handle
that can be held on both sides while shaving, however this new handle is used
differently
which is disclosed. Old safety razors have 2 edges where the user shaves back
and forth
across their skin while shaving. Both edges are used at the same time until
the blades are
dull and the double edge razorblade needs to be replaced. This new symmetric
handle is
used differently than old safety razors; the user would hold a razor handle
(1st handle
side) that is comfortable to grasp and hold while shaving with the 1st shaving
side. When
the user is done using the 1st side and the blades are dull, then the user
would flip the
cartridge to the 2nd shaving side and the user would turn and rotate the
handle to the
second handle side which is opposite the St handle side and continue to shave.
The 2nd
side of handle is usually an identical and mirror image of the 1st handle side
and is
comfortable to grasp and hold and to shave with. After the 2nd side is dull
the user would
throw away this dual sided disposable razor and buy another dual sided
disposable razor
and repeat these steps. No other razor handle in the market works this way.
1001571 The handle can be ergonomically shaped on both sides so it's very
comfortable to hold the razor handle on both sides There can be finger grooves
or areas
that are inset or raised that can allow the finger to rest comfortable and
easily and allow
the consumers to hold the handle comfortable and shave conveniently with a
convenient
and comfortable feel while holding the razor on both the 1st handle side and
the 2nd
handle side.
1001581 The dual sided disposable razor handle can be any shape, size, design
know now or developed in the future. The dual sided disposable razor handle
can be
made of steel, plastic, rubber or any material or combination of materials.
The handle can
be solid, hollow and bored out from the bottom of the handle. One side can be
solid and
- 32 -

WO 2021/113315
PCT/US2020/062824
the side has hollow areas. The dual sided disposable razor handle can be made
of any
material or combination of materials. It can be made of steel, or any heavy
material,
plastic, rubber, or any soft type of materials and any combination of
materials and can be
made of any type of materials The handle can be one to any number of pieces
1001591 The top of the handles can have any type of connectors or any kind of
attachment mechanisms to connect to a dual sides razor head that's known now
or
developed in the future. The handle & dual sided razor head can be one piece
or several
pieces or can all molded together. These areas can have hinge areas to allow
the cartridge
to flex back and forth while shaving.
1001601 Attachment
1001611 The dual sided disposable razor cartridge can be attached to any kind
of
razor handle know now or developed in the future. The dual sided cartridge
that has
parallel shaving surfaces and the cartridge can have any type of attachment or
connection.
It can be made of plastic rubber, steel or any type of material known now or
developed in
the future. The attachment can be like any razor attachment in the market
known now or
brought to market in the future. The attachment can be permanent or removable.
The
attachment could have no attachment and be molded as part of the handle. The
dual sided
disposable razor cartridge can be attached directly to the handle or to
handle, swivel
arms, arms or prongs or any part of the razor, handle or cartridge or any part
of the razor.
The dual sided disposable razor cartridge can be molded into the handle and
part of the
handle or the razor and be one unit or separate pieces or units.
1001621 2) New Faster & Easier Dual Sided System Razor & New Handles
1001631 This new faster and easier dual sided system razor works similar to
the
dual sided disposable razor except the cartridge is replaceable when both
sides have been
used and are dull, then a new cartridge can be replaced and put on the handle.
1001641 When consumer buy a typical system razor they use the razor cartridge
until the blades are dull, then the consumer throws it away and puts another
cartridge on
the handle. The new system razor has improvements to allow the consumer to use
the 1st
- 33 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
side of the razor and when dull switch to the second side faster and easier.
This makes
using this dual sided system razor more convenient for consumers and to allow
them to
have 2 sides of fresh blades every time they buy and use system razor
cartridges. To offer
twice the shave with every system razor they buy is a huge value proposition
for the
consumer. Consumers always love a new set of blades and when they buy this
dual sided
system razor it allows consumers to have 2 sets of fresh blades to use during
each use of
every razor cartridge. The new system razor offers many benefits like twice
the shave and
the opportunity to use 2 sets of blades during the entire life of using every
razor cartridge.
1001651 The method of using this faster and easier dual sided system razor;
1001661 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.
1001671 When the system razor flips to the other side the cartridge goes over
a
built-in deflector on the top of the swivel arm cartridge or handle. When the
consumer
uses the 2nd side completely and the blades are dull then the consumer can
disconnect the
cartridge by pulling the cartridge away from the handle or by a button and
throw away
Then the consumer would put another new dual sided razor cartridge on the new
system
razor and continue using like described above, it can be used any way possible
not just
what is explained above.
1001681 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

WO 2021/113315
PCT/US2020/062824
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.
1001691 Handle
1001701 The dual sided system razor handle is symmetric handles that can be
held
have two separate uses on both sides. Old safety razors usually have a round
handle that
can be held on both sides while shaving, however this new handle is used
differently
which is disclosed. Old safety razors have 2 edges where the user shaves back
and forth
across their skin while shaving. Both edges are used at the same time until
the blades are

(1st handle
side) that is comfortable to grasp and hold while shaving with the 1st shaving
side. When
the user is done using the 1st side and the blades are dull, then the user
would flip the
cartridge to the 2nd shaving side and the user would turn and rotate the
handle to the
second handle side which is opposite the St handle side and continue to shave.
The 2nd
side of handle is usually an identical and mirror image of the 1st handle side
and is
comfortable to grasp and hold and to shave with. After the 2nd side is dull
the user would
throw away the dual sided razor cartridge and replace with another two sided
razor
cartridge and repeat these steps mentioned. No other razor handle in the
market works
this way.
1001711 The handle can be ergonomically shaped on both sides so
it's very
comfortable to hold the razor handle on both sides. There can be finger
grooves or areas
that are inset or raised that can allow the finger to rest comfortable and
easily and allow
the consumers to hold the handle comfortable and shave conveniently with a
convenient
and comfortable feel while holding the razor on both the 1st handle side and
the 2nd
handle side.
1001721 The dual sided system razor handle can be any shape, size, design know
now or developed in the future. The dual sided system razor handle can be made
of steel,
plastic, rubber or any material or combination of materials. The handle can be
solid,

hollow and bored out from the bottom of the handle. One side can be solid and
the side
has hollow areas. The dual sided system razor handle can be made of any
material or
combination of materials. It can be made of steel, or any heavy material,
plastic, rubber,
or any soft type of materials and any combination of materials and can be made
of any
type of materials. The handle can be one to any number of pieces.
1001731 The top of the handles can have any type of connectors or any kind of
attachment mechanisms to connect to a dual sides razor head that's known now
or
developed in the future. The handle & dual sided razor head can be one piece
or several
pieces or can all molded together. These areas can have hinge areas to allow
the cartridge
to flex back and forth while shaving
1001741 The dual sided system razor cartridge can be attached to any kind of
razor
handle know now or developed in the future. The dual sided cartridge that has
parallel
shaving surfaces and the cartridge can have any type of attachment or
connection. It can
be made of plastic rubber, steel or any type of material known now or
developed in the
future. The attachment can be like any razor attachment in the market known
now or
brought to market in the future. The attachment can be permanent or removable.
The
attachment could have no attachment and be molded as part of the handle. The
dual sided
system razor cartridge can be attached directly to the handle or to handle,
swivel arms,
arms or prongs or any part of the razor, handle or cartridge or any part of
the razor. The
dual sided system razor cartridge can be molded into the handle and part of
the handle or
the razor and be one unit or separate pieces or units.
1001751 13) 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
- 36 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
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.
1001761 With Razor cartridges that don't have flexible blades,
floating blades or
moving blades, the blades are in a fixed position and they do not move, so
when these
type of razor cartridges and razors shave over the user skin the razor blades
do not move.
When the razor cartridge glides over a user's skin in different contours, the
blades are
fixed and there's no leeway or give.
1001771 The advantage of a two sided razor having flexible blades is the user
can
use one side of the razor with a comfortable shave that flex blades technology
offers and
when the blades are dull then switch to the other side and continues shaving.
This give
the consumer twice the shave, the convenience of having another fresh blades
to use and
saves them money.
1001781 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. So when 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.
1001791 The Flex Blades ¨ Floating Blades- Moving Blades on both sides can
work in unison or move independently.

1001801 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.
1001811 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. With a two-sided razor cartridge, 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. These 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
1001821 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.
1001831 In one embodiment 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
- 38 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
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 fl ow 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.
1001841 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.
1001851 In one embodiment 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. 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 or any
direction.
1001861 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
- 39 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
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.
1001871 In one embodiment 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. This way the movements of the blades are
calculated and can
be within strict tolerances and precise progressive blade exposures on each
side of the
razor cartridge. The blades on the opposite side can move as well but the
opposite side is
not being shaved with. When 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
1001881 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.

1001891 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.
1001901 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.
1001911 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. Or 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.
1001921 There could be a center structure that connects the blade, blade
supports /
blade frame or blade carriers. This can be part of the frame and can be one to
any number
of pieces. 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
1001931 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
1001941 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. When
the Blades are welded to the frame 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.
Then 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. Like described 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.
1001951 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. In one
embodiment in the
- 42 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
middle of the section there can be areas split to where the blade can flex or
move. This
area can be designed to have protrusions or holes or designed to be made into
hinge and
flex in the middle or any location.
1001961 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.
1001971 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. Then 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
1001981 This progressive geometry and blade exposed with progressive geometry
can be done with any means possible and any way that has been disclosed in
this
application.
1001991 In one embodiment, when the Flex Blades ¨ Floating Blades- Moving
Blades including the blade carrier or blade frame are stacked above each other
in a razor
cartridge, 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-

CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
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.
1002001 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.
1002011 This same when the user rinses their razor with water to clean the
hair and
shave gels and cream and shave better etc. through the razor cartridge. When
the water is
being applied its usually in the shower or sink and the there's movement of
the water and
this allows the flexible blade on both sides to moving allowing a water flow
through to be
constantly moving all the way to the 2nd side not being used and exiting the
razor
cartridge. With single sided razors, the flex, floating and moving blade
usually has plastic
or cartridge materials or parts on the back side and does not have as much of
a water flow
through.
1002021 In one embodiment, 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. Where 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 that goes through each blade
carrier,
blade frame or blade... can have smaller or narrower sections. This skinny or
narrower
section is where the top or flat area of the blade carrier goes through and
these narrower
sections are precise measurements so the blade can move upward or any
direction with
more precise tolerances. 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.
1002031 In one embodiment, the blade carrier or blade frame can be welded or
attached together. In one embodiment, 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.
1002041 In one embodiment, 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.
1002051 In one embodiment 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
- 45 -
CA 03160373 2022- 6- 1

WO 2021/113315
PCT/US2020/062824
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. This can be
any shape or
be in any location but for example like a peanut shape 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.
[00206] In another embodiment 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.
