Shaving system comprising a razor handle
A shaving system including a bifurcated razor handle ( 1,90 ) having a unitary, two-shot plastics molding having a pair of hinges ( 4 ) with elastomeric springs ( 11 ) joined by a cartridge mounting portion ( 30,91 ) which receives the bottom side of a generally flat, multi-blade cartridge ( 60 ) in fixed, snap-fit relation. The cartridge is retained in a dispenser ( 80 ) beneath a resilient leaf ( 84 ) and pressed onto the mounting portion along an engagement axis E normal to the shaving plane, the leaf being received in a recess ( 48 ) between the mounting portion and the cartridge. The cartridge is then retracted from the dispenser along a retraction axis R generally parallel with the shaving plane. The mounting portion includes digit-receiving regions 40 for pressing the mounting portion onto the cartridge, an ejection element ( 41,141 ) for disengaging the cartridge from the handle, and an elastomeric skin-engaging platform ( 51 ) arranged in advance of the shaving plane.
1. A razor handle for use with an associated disposable shaving cartridge, the associated cartridge having at least one cutting edge lying in a shaving plane and being arranged to exert a cutting action when the shaving plane is moved across a user's skin in a shaving direction, the razor handle comprising:
a mounting portion; and
a handgrip portion;
the mounting portion being adapted to releasably retain the cartridge in an installed position in fixed relation to the mounting portion, the mounting portion being pivotable relative to the handgrip portion about a pivot axis comprising at least one hinge, the hinge providing a return force that urges the mounting portion resiliently to a rest position with respect to the handgrip portion;
wherein the mounting portion includes a fixed skin engaging structure having at least one skin engaging surface;
the skin engaging surface being arranged in the shaving plane in fixed relation to the mounting portion;
and in front of the at least one cutting edge when considered in the shaving direction in the installed position of the cartridge;
such that the skin engaging surface frictionally engages the user's skin in advance of the at least one cutting edge as the shaving plane travels across the user's skin in use;
wherein the skin engaging surface comprises a surface of a body of elastomeric material;
wherein the body of elastomeric material is moulded integrally with the handle; and
wherein:
the hinge of the mounting portion includes an elastic portion of the said body of elastomeric material, and
said elastic portion providing a return force that urges the mounting portion resiliently to a rest position with respect to the handgrip portion.
2. A razor handle according to claim 1 , wherein the said body of elastomeric material extends to provide a gripping surface of the handgrip portion.
3. A razor handle according to claim 1 , wherein the pivot axis defines the intersection of first and second orthogonal planes,
the first plane lying parallel with the shaving plane such that the shaving plane lies between the first plane and the user's skin in use, the second plane lying in advance of the or each cutting edge when considered in the shaving direction.
4. A razor handle according to claim 1 , wherein the pivot axis is substantially parallel with the cutting edge, and the mounting portion is not free to pivot about any other axis.
5. A razor handle for use with an associated disposable shaving cartridge, the associated cartridge having at least one cutting edge lying in a shaving plane and being arranged to exert a cutting action when the shaving plane is moved across a user's skin in a shaving direction, the razor handle comprising:
a mounting portion; and
a handgrip portion;
the mounting portion being adapted to releasably retain the cartridge in an installed position in fixed relation to the mounting portion, the mounting portion being pivotable relative to the handgrip portion about a pivot axis comprising at least one hinge, the hinge providing a return force that urges the mounting portion resiliently to a rest position with respect to the handgrip portion;
wherein the mounting portion includes a fixed skin engaging structure having at least one skin engaging surface;
the skin engaging surface being arranged in the shaving plane in fixed relation to the mounting portion;
and in front of the at least one cutting edge when considered in the shaving direction in the installed position of the cartridge;
such that the skin engaging surface frictionally engages the user's skin in advance of the at least one cutting edge as the shaving plane travels across the user's skin in use;
wherein the skin engaging structure comprises a flexible cantilever structure formed from a body of elastomeric material;
wherein the body of elastomeric material is moulded integrally with the handle; and
wherein:
the hinge of the mounting portion includes an elastic portion of the said body of elastomeric material, and
said elastic portion providing a return force that urges the mounting portion resiliently to a rest position with respect to the handgrip portion.
6. A razor handle according to claim 5 , wherein the said body of elastomeric material extends to provide a gripping surface of the handgrip portion.
7. A razor handle according to claim 5 , wherein the pivot axis defines the intersection of first and second orthogonal planes,
the first plane lying parallel with the shaving plane such that the shaving plane lies between the first plane and the user's skin in use,
the second plane lying in advance of the or each cutting edge when considered in the shaving direction.
8. A razor handle according to claim 5 , wherein the pivot axis is substantially parallel with the cutting edge, and the mounting portion is not free to pivot about any other axis.
