## Abstract

The invention is directed toward a shaving razor system. The razor system has a handle and a razor cartridge. The handle has at least one skin interconnect member in pivotal relation to a proximal end portion of the handle. The razor cartridge has a housing, at least one blade, and at least one opening which extends through the housing. The razor cartridge is engaged with the skin interconnect member when the skin interconnect member is disposed within the opening securing the razor cartridge to the proximal end portion of the handle. The razor cartridge is in a pivotal relation with the handle, but not with the skin interconnect member. A pivot point of the razor system is desirably disposed near the front blade of the cartridge. Axes of movement in the razor system can be provided by different physical order of connections of razor components.

## Claims

### Claim 1

A shaving razor system comprising:
a razor cartridge, said razor cartridge comprising a housing having a front side, a back side opposing said front side, and a front blade mounted to said housing, said front blade is closer to said front side than said back side of said housing; and
a handle, said handle comprising a proximal end portion, a distal end portion, at least one interconnect member, a first A1 pivot mechanism that enables rotation of said at least one interconnect member about a first axis A1 relative to said handle, and at least one second pivot mechanism that enables rotation of said at least one interconnect member relative to said handle about axis A2, A3, A4, or A5;
wherein said axis A2, A3, A4, or A5 are not parallel to said axis A1;
wherein an order of physical connection of components comprises:
said razor cartridge removably connected to said at least one interconnect member, said at least one interconnect member connected to said at least one second pivot mechanism to enable rotation about said axis A5, A4, A3, or A2, said at least one second pivot mechanism to enable rotation about said axis A5, A4, A3, or A2 connected to said first A1 pivot mechanism to enable rotation about said axis A1, and said first A1 pivot mechanism connected to said handle;
wherein said axis A1 is (i) transverse to a longitudinal axis of said handle and (ii) parallel to a longitudinal axis of said front blade;
wherein said at least one interconnect member projects through an opening in said housing of said razor cartridge such that a skin interfacing surface of said at least one interconnect member interfaces with a user's skin during a shaving process; and
wherein said opening extends through said housing from a top surface to a bottom surface of said housing, and wherein a perimeter of said opening at said bottom surface is larger than a perimeter of said opening at said top surface.

### Claim 2 (depends on 1)

The shaving razor system of claim 1 wherein said at least one interconnect member in said opening of said housing provides a pivot point P for pivoting said razor cartridge about the first axis A1 relative to said handle.

### Claim 3 (depends on 1)

The shaving razor system of claim 1 wherein said at least one interconnect member is connected to said proximal end portion of said handle by said first A1 pivot mechanism, and wherein said first A1 pivot mechanism comprises one or more bearings.

### Claim 4 (depends on 1)

The shaving razor system of claim 1 wherein said skin interfacing surface comprises a fluid element, a thermal element, a skin scrubbing element, a hair trimmer, an epilator, or any combination thereof.

### Claim 5 (depends on 1)

The shaving razor system of claim 1 wherein said at least one interconnect member comprises a trapezoidal prism shape.

### Claim 6 (depends on 1)

The shaving razor system of claim 1 wherein said skin interfacing surface is not disposed on a shave plane formed by a guard and a cap of said razor cartridge.

### Claim 7 (depends on 1)

The shaving razor system of claim 1 wherein said handle comprises a mass of about 57 grams to about 150 grams.

### Claim 8 (depends on 1)

The shaving razor system of claim 1 wherein said opening of said housing of said razor cartridge is releasably engaged with said at least one interconnect member to replaceably secure said razor cartridge to said proximal end portion of said handle.

### Claim 9 (depends on 1)

The shaving razor system of claim 1 wherein said at least one interconnect member has a length from about 20 mm to about 40 mm, a width from about 1.5 mm to about 5 mm, a volume greater than about 300 mm3, and a skin interfacing surface area of about 40 mm2 to about 120 mm2.

### Claim 10 (depends on 1)

The shaving razor cartridge of claim 1 wherein one or more ports are disposed on said skin interfacing surface.

### Claim 11 (depends on 1)

The shaving razor system of claim 1 wherein said at least one interconnect member is connected to said proximal end portion of said handle by said first A1 pivot mechanism, wherein said first A1 pivot mechanism comprises one or more sliding contact bearings, rolling element bearings, or combination thereof.

### Claim 12 (depends on 1)

The shaving razor system of claim 1 wherein said handle comprises a handle neck area at said proximal end portion of said handle and a handle main body at an elongated gripping portion of said handle, and wherein a PL1-to-PL2 included angle between a shave plane S formed by a cap and a guard of said razor cartridge and a midplane PL2 formed by said handle main body is about −60 degrees to +90 degrees.

### Claim 13 (depends on 1)

The shaving razor system of claim 1 wherein said handle comprises a handle neck area at said proximal end portion of said handle and a handle main body at an elongated gripping portion of said handle, and wherein a PL2-to-PL3 included angle between a midplane PL2 formed by said handle main body and a midplane PL3 formed by said handle neck area is about −100 degrees to +100 degrees.

### Claim 14 (depends on 1)

The shaving razor system of claim 1 wherein said at least one interconnect member is not pivotal relative to said housing.
