A shaving device comprising a handle, a support member, a blade cartridge retention frame, and a replaceable blade assembly. The support member is disposed about a first end of the handle and includes at least one arm extending outward from a yoke. The blade cartridge retention frame includes a blade cartridge retention frame magnet and is coupled to the at least one arm and configured to pivot about a pivot axis. The replaceable blade assembly includes a blade assembly magnet and a blade assembly body having a face with a razor blade. The blade assembly magnet and the blade cartridge retention frame magnet are configured to create a repulsive magnetic force therebetween to releasably couple the replaceable blade assembly to the blade cartridge retention frame.

A two-sided back shaver handle has an elongated member. A blade attachment located on the inner side is at a blade end of the elongated member opposite a grip end. A sponge is wrapped around the elongated member on the outer side of the elongated member opposite a grip end. The sponge has a strap wrapped around the elongated member. An elongated sponge can be located in a direction along a length of the elongated member on an outer side, wherein the elongated sponge extends longer in a length between the grip and the blade end than a width between the left side and the right side. The elongated member can be s-shaped with a convex surface contour on the outer side between the grip and the blade end.

A skin engaging member suitable for use in a hair removal device, said skin engaging member comprising ethyl vinyl acetate having a low level of vinyl acetate and a water soluble polymer.

A safety razor shaves back hair of a user. An elongated back shaver handle has a grip and a blade end. A blade group has a sharp blade and a guard parallel thereto. A substrate structure is coupled to the blade end. The substrate structure is adapted to hold both the blade group and a support on a front surface with the blade group and the support spaced a distance. The blade group and the support each extend from the front surface of the substrate structure at a height sufficient to avoid loose skin of the user touching the front surface of the substrate structure. The support can be either a blunt protrusion or another blade group.

A liquid dispensing unit for a hair removal device with a reservoir and an applicator in liquid communication with the reservoir. A first and second connector are in liquid communication with the reservoir. The first and second connector each have a respective first and second valve. A resilient tube is disposed between the connectors. The resilient tube has a neutral position with both valves closed and a second position with one valve open and one valve closed.

A shaving razor having a cartridge containing a razor blade coupled to a monolithic yoke. The yoke is formed from a single piece of material possibly by injection molding. The yoke has a bridge and a pair of cross pieces each coupled to the bridge by a living hinge. The cartridge is coupled to the cross pieces and spans between the cross pieces.

The invention relates to a shaving device for skin hairs. The device comprises a skin-contacting surface structure (14, 15), a cutter (6) for cutting hairs in a hair-cutting area (16), a shape-changing smart material (7), and a controller for controlling activation of the shape-changing smart material during use of the shaving device. The shape-changing smart material is configured, arranged and effective to adapt the relative position and/or relative orientation between at least part of the skin-contacting surface structure (14) and at least part of the hair-cutting area (16).

Shaving razors and cartridges are featured which include one or more removably attachable shaving aid accessories.
