Abstract

Disclosed here are shaving razor systems and methods including razor handles that dock with razor cartridges. In some embodiments, a handle is configured to dock with a razor cartridge using a single hook configured to mate with a cartridge tab. In some embodiments, a central pushrod is mounted with a spring into the handle, and is configured to exert a pushing force on the mounted cartridge. In some embodiments, to eject the cartridge, the single hook may be pushed to pivot to the side of the cartridge tab, and thereby release the cartridge by ejecting it with a spring loaded pushrod.

wherein the docking structure includes a single receiver section, the single receiver section including a central tab for docking to a handle, wherein the central tab includes a fulcrum point near the guard at which a handle docking system may hook, and about which a force would be imparted on the cartridge from the handle when in use,

wherein a closest distance between the fulcrum point of the central tab and the shaving plane is less than 1 mm for a better shave with less skipping and less torque twist on the razor cartridge and a better pull across the target skin and hair; and

7. The system of claim 1 wherein the receiver section also includes elastomeric coating.

8. The system of claim 1 wherein the guard includes the guard bar made of a material, and wherein the receiver section is coated in the same material that the guard bar is made of.
