Magnetic attachment for shaving cartridge
Shaving systems are disclosed that include a replaceable shaving assembly and a cartridge connecting structure for connecting the shaving assembly to a handle. In preferred implementations, the cartridge connecting structure has a magnetic portion configured to help draw the cartridge onto the handle and retain the cartridge in place when the razor is not in contact with the skin, and a mechanical engagement that provides the necessary retention forces required to keep the system intact during shaving.
1. A method of shaving comprising:
providing a handle including a distal end having an appendage protruding therefrom, and upper and lower gripping surfaces, and a shaving assembly mounted on the handle, the shaving assembly including:
an interface element having a receiving portion in form of a hollow, central cavity configured to receive the appendage, and
a blade unit pivotably mounted on an interface element and including a plurality of blades having cutting edges, and
a magnetic portion configured to provide a magnetic force between the handle and shaving assembly, the magnetic portion comprising at least one magnet disposed in a recess at an end of the appendage, and a ferrous material disposed in the hollow, central cavity of the receiving portion;
inserting the appendage into the receiving portion such that the magnetic force retains the shaving assembly on the handle; and
contacting a skin surface with the cutting edges to shave the skin surface.
2. The method of shaving of claim 1 , further including drawing the cutting edges of the blades across the skin surface.
3. The method of shaving of claim 2 , wherein the receiving portion and the distal end of the handle are configured to provide a mechanical engagement that retains the shaving assembly on the handle when the shaving assembly is drawn across the skin.
4. The method of shaving of claim 1 , further comprising rotating the handle between approximately 15 to 105 degrees from a reference skin plane during shaving.
5. The method of shaving of claim 1 , further comprising removing the shaving assembly from the handle.
